Pixel 5 multiple sensors and software issues - Google Pixel 5 Questions & Answers

Hello everyone,
Since a few weeks I have several issues with my Pixel 5, mostly sensors issues (compass, gyroscope, proximity, etc.) but also some weird system software behaviors.
It began mid November when I woke up and realized my phone restarted on its own during the night.
Since then I have these issues :
- Compass not working
- Proximity sensor not working
- Gyroscope working only for a few seconds at start, and then completely stop.
- Phone freezes almost every time I unlock it. It freezes for like 3 to 5 seconds, the colors of the screen are dimmed, and then it finally unlocks.
- When the phone is playing audio content (songs, ring, alarms, etc.) the sound cuts out every 10 seconds (exactly) for like one second and then come back.
- In random moments, the phone will display an error "Process is not responding".
- The small proximity sensor LED is always blinking if I enable "Always on Display" feature.
- Finally, I can't install any Google Play System updates. I perform the installation, reboot the device, but a few minutes after this restart the phone will restart on its own and the Google Play System update will not be not applied (I can perform it again, and again, and again, etc.)
I tried several things : safe mode, factory reset, but I also reinstalled the whole Android 13 image with adb and fastboot. The issues still continue.
I sent the phone to be repaired by Google but they were "unable to reproduce these issues".
They also told me the phone has been damaged by water, which seems weird because the phone didn't had any incident with water that I can remember. I think I had one time the message "Liquid or debris in USB port" about six months ago, I don't understand why the problems would suddenly appear now.
They sent it back without any repair.
I don't know what to try anymore, I was convinced it was only a software issue (and that all the issues were related) but even reinstalling the whole android image didn't solve it. So is it a hardware issue after all ?
Any recommendation on how to process with these issues would be much appreciated. Or maybe I need to give up and buy a new phone ?
Thank you.

It's either water damaged or it's not. Google saw the moisture sensitive indicator(s) showed water exposure. So somehow this happened. If it's been exposed to water the first thing to do is disconnect the battery and allow it to dry out completely then see what you got.
At this late stage the damage may be permanent.
If it was salt water it's already dead. Sweat is salt water... keep 'em in a good case and keep it clean.

Thank you for your response.
But what I don't understand is why the issues would suddenly appear months after its contact with water, which was only rain by the way.
I am 100% sure it did not had any water incident at the time the issues appeared.

Water damage is insidious which is why manufacturers won't warranty it. Damage can be delayed sometimes taking weeks or months to become apparent.

buying used P5 now due to water damage :-(
Almost went for P7, great device, but I think I'll be fine until the P8 and hopeful Google will have a good trade in value like this year.
$200 for mint P5
$540 + shipping taces etc I believe if you have one od those.
but I think I'll save the $300 for now.. If i had the cash I'd go P7, but P5 is a wonderful device,

Dead

Hello,
Yesterday my Diamond had died I think
It was frozen and I did a soft reset, screen stays black and nothing happend anymore.
Pulled out the battery, put it back in, and try to turn it back on. It vibrates after a few seconds but the screen stays black.
every help would be great!
Greetings!
Michiel
It might be low on battery so have you tried recharging it?
when i connect it to the power cable nothing happens, the enter button isn't lighting up.
when i connect it to my pc I can browse to the internal storage normally, but it won't charge the battery.
now I'm really confused...
Take out your battery and sim card and leave it out for about 20 minutes and then put it back. During this time, also have your device plugged in (without the battery).
Reflash Everthing
I've pulled out the battery + sim for more than 30 minutes, reloaded the official HTC rom and still the screen is black.
It starts up, vibrates, makes the start sound but the screen remans black.
Now I want to put the orginal HTC SPL back on it, but it doesn't completes the procedure.
Anyone? thnx again!
I got exactly same problem
this has happened to me twice during the past year. the screen was black, although it did vibrate when I turned it on. both times it fixed by itself overnight, very strange.
what I saw is that both times it happened after a long ride with the car, I suspected that due to the prolonged exposure to air conditioning, when I took it out it condensed on the warm motherboard (it was used as a GPS) and some shortcircuit occured.
Unfortunately, 3 weeks ago, again after a long trip with the car, when I took it out it 'died' in 5 minutes (with 100% battery), did not even vibrate anymore when powered on, and never woke up eversince. It is now in service since the 15th of August, with a status on the website of the official HTC service company in Romania (Cirma Electronics) of: "waiting for spare parts" for 5 days...
My guess is that either the MB or the screen fried because of a design issue which caused the condensed vapors to form on some contacts inside...
It sounds as if the device is 100% operational with the exception that the LCD is out. Correct? Or, have you experienced other problems? Try powering up you Diam, then shine a flashlight directly at the screen. If you can see your interface then you have a dead backlight & need a new LCD. If you do not see the image then the LCD itself is defective {Apparently a common problem} & you'll need a new LCD. Either way you should contact HTC service as you have a 2 YR warranty.
@ cocomic: Where is Your Diam on these trips, A windscreen mount or a console mount? If it's a console mount, most likely you have an air vent blowing directly at it & that's just asking for moisture build up. But, if it was a "moisture" issue as you stated, then HTC would not be fixing it for free. They would see the oxidation from the moisture & say that it's your fault for getting it wet, & charge you out the ass for that part. {That's why ALL devices have LDIs} If you use a windscreen mount, then you have your device sitting in the sun for a long time! Sunlight KILLS LCDs!!! It may be more likely that you burned your screen by having it exposed for long periods. But it's probably just the issue that many people have. If you go to HTCforums you will see a lot of people have LCD issues.
If you have warranty return it to the store.

I have a windscreen mount, the air vent doesn't blow directly on the device. furthermore, the sun couldn't have burnt the LCD as the last time it died (for good), it was 11 PM.
the phone is in service and has the online status on their website: "the phone is in the lab, waiting for spare part". this means that whatever the issue is, hopefully it's gonna be fixed under warranty.
nevertheless, I find it appalling that a device built in 2008 has huge design and construction faults causing it to malfunction whenever used in a car with the AC turned on...
I'll keep you posted on the outcome
later edit: update: I've just got off the phone with a secretary at the htc service. apparently the motherboard fried and they ordered a new one. from what she said only the case will remain the same, it may be that the lcd display was caught in the chain reaction . the bad thing is that I will probably have to wait for another week, the good thing is that I will get an almost new phone...
as they didn't say anything about the LDI, it's either that the condensed vapors didn't touch it, only the circuits, or the fault did not come from the humidity... one can only guess...
It may not have been condensation that caused the problem. It could be that your Mainboard had a problem that was amplified by your trips in the car. Either way, you get a factory refurbished Diamond, & that's jus' sweet. I have to call them this week about my Diam because my front cam isn't working. I never really use it, but if it's covered, I might as well make them flip the bill while I can.
no, really, do that... i remember that a few weeks before the 'incident' my rear camera stopped working, too... i never payed too much attention as i considered it to be just a spb mobile shell software issue which would have eventually gone away after a hard reset or something...
you are probably right, my MB was slowly dying, organs failing (i have just watched a house md rerun, sorry )... if you have the possibility to have it checked while it's still in warranty and have the camera fixed while at it, why not?
I'm moving this, as it has no pertinece to the original topic. This link; http://forum.xda-developers.com/showthread.php?p=4476473#post4476473 is a post I started to see if anyone else had these issues. Read the update on the first post

HOW TO: fix Droid/Milestone touchscreen lack of responsiveness and Ghost Touch issues

NOTE: THIS SOLUTION IS POTENTIALLY DAMAGING AND MAY NOT WORK FOR EVERYONE
PROBLEM: touch screen acts erratic, notification bar keeps opening, screen appears to be touched by someone else continuously (Ghost Touch), and parts of the screen DO NOT RESPOND TO TOUCH.
MY OWN SPECIFIC CASE: I had the Ghost Touch issue for 3 days suddenly without intro, which often used to go away after a reboot or two, then phone worked normally after I removed the battery and left it in a dry area (in a closed drawer between books, no air entering, very dry atmosphere), however the RIGHT SIDE of the screen (Search button, rightmost letters [L and Delete and sometimes ENTER] do not work. If the phone is in normal landscape, you cannot open the notification bar by dragging it normally.
DIAGNOSIS: for some people, the problem is more severe. The Digitiser itself could be malfunctioning and has to be fixed, while for others it could be a true problem with the screen itself. However, for MANY OF US, it is a problem of HUMIDITY. The humidity sensors are causing the phone to act like that. Some say part of this problem happens because the way the keypad affects the phone internally as you open and close it a lot.
SOLUTIONS:
1- To be safe: send the phone to the shop. Ask them to open the phone and apply an extra layer of insulation, in case the digitiser and the screen are okay.
2- If something is faulty, replace it at the shop.
3- MY OWN SOLUTION: based on something I read many times, the solution was to apply DRY HEAT for at least 45 mins. What I did, based on averaging out many experiences I read online, was to remove the SD Card and SIM, remove battery, I heated up a toaster oven for 10 minutes, waited until the temperature was at about 60-70 degrees Celsius, SHUT DOWN THE HEAT, put the phone on its screen on a plate, screen facing down and covered by a cloth to protect it from direct contact with metal, then all inside the oven. The oven is a relatively big one, so phone was AWAY FROM A SOURCE OF DIRECT HEAT. I closed the lid, then every while 15 minutes I would heat the oven for 40 seconds to maintain the temp. This is LIKE (ALTERNATIVE SOLUTION) leaving your phone in the glove compartment of your car while its parked in a sunny spot, to find it really hot in the morning and tough to touch for a while. TO CONTINUE, after the phone was out of the oven (I can't believe I am saying this), I left the phone overnight in a dry area for 8 hours (could need less time). Then, I put everything back in, plugged it, and THE PHONE IS WORKING PERFECTLY NOW!
NOTE that solution number 3 could affect your keyboard buttons if heat is too much. It may cause the glue holding the keys to melt a bit. Be delicate with your keyboard after you restore your phone.
Again, I only did this YESTERDAY. With the exception of some keypad stickiness, the phone is working perfectly now.
I hope this was useful

EDIT: Today is the First of May, phone is still working without a glitch
N.B. Press the Thank you button if you wanna congratulate me on daring to toast my milestone in the name of scientific inquiry
SECOND EDIT: Phone did it again for 2 days. Applied the same method, and it worked again. I think partially it happened because I was in a very humid location.
That didn't work for me, I had no option but to replace the touchscreen/gorila glass.
I love the idea of toasting a milestone
Thought with all my aggression against Moto, I think I just might leave it in there
Luckily I dont have these problems so I wont get tempted

I have to admit, I cared litte whether or not this actually worked. I just wanted to toast it But it did work, so
Pretty tempted to try this out, I think I will when I have free time.
My phone had the dead zone problem for 2 months now, but in some very rare cases, like when it's a very hot day, the screen will work normally for a minute or something. Then it goes back to dead part. I assume this would fix it?

If it DOES indeed work on hot days, then it means the phone is not entirely dead. But I would suggest you do something less drastic first, such as the Glove Compartment method. No responsibility though
If you're trying to remove moisture, you could also try putting it in a baggie of crystaline cat litter (NOT the clay kind!) - this stuff is sold at a MUCH higher price as a way to save a phone from water damage, but it's the exact same substance. Does a great job removing moisture. It's the same sort of silica gel that's in those packets in medicine/vitamins that says "Dessicant - do not eat".
Or you could just put it in a sealed bowl with raw rice for a couple of days... this is the best and cheapest way (and then you have the silicon "grains", the ones that you find in shoe boxes or computer parts boxes).

Pretty sure that rice doesn't do anything, I don't know how that started as a suggestion, but its not better than anything else; its not known to be absorbant, but the silicon is.
I've tried the method but the right segment of the digitizer still doesn't work.
My biggest issue with regards to "lack of responsiveness" are the 4 capacitive buttons. Pressing the Home key is always hit and miss. I know I hit it all the time because I can feel the vibration feedback but it only goes to homescreen 50% of the time.
Will also be testing this out as soon as I have the spare time. My screen started acting up after I accidentally put my milestone in a small beer spill at a party Hopefully this will work out for me too!

Luckily for me, I was still under warranty, heh. Cause I had insurance. This is my second Droid this has happened to. Hopefully my replacement won't do the same thing.
How many times did you reheat the oven? I tried just once and it didn't help. My phone has been having this problem since January.

Well, depends on your over. Mainly I was trying to maintain a temp varying between 50-60 c. Mostly 50, but sometimes 60 to up the ante a bit and make sure things stay warm. 30 minutes at least. However, I have to say that I did this twice in 6 weeks, and after that the phone just died again, and I found my warranty card and sent it there to be fixed, and they fixed it, but ruined something else.
If you have the warranty card, take your phone and send it to them Someone told me the method worked and the phone has been good for quite a while, but most of us seem to re-experience the issue after a while.
I've been having these issues for a few days now too, and I think I know why. I've been using this Milestone for 4 months now, and I never had this problem until a few days ago. What I noticed yesterday was that after some acting up, the phone started working properly again. So I ran Touch Test. And I noticed that if I pressed really hard on the top side of the phone(where the logo and the ear piece are located) it started acting up again. My first impression was that the glue holding down the gorilla glass was loose. So I left the phone as usual on my night stand and then I tried the same thing with the pressing on the same area. Guess what? It didn't happen again. Now there seems to be no problem. So I tried to remember what happened yesterday before the screen started acting up, and I remember talking to my wife for a while when I was in my car. Yesterday was a pretty hot day and I was a little sweaty when I talked to her. Now since only that specific part with the earpiece was causing this issue(I tried pressing equally hard on other areas without any problem my guess is that the insulation between the earpiece and the touchscreen has been breached. Maybe because of all the sweat that went in there in time. You know the salt and acids in the swear are known to melt things, and poor quality glue is among them.
How to fix this? I do not know yet, but I do have a good idea that I'd like to share. I want to buy a screen protector foil, and put just a little band around the ear piece. That would probably lower my in-call volume, but since the Milestone is very loud anyway I hope it the quality of the calls won't be too much affected. After that I'll use it in normal conditions again and see if the ghosting happens again.
try completely formatting your SD CARD/PARTITION.
& then reinstalling using (FAT 32/EXT 2, 3, or 4)
sometimes traces from the previous ROM might interfare with touch codecs (maybe)
just trying to help. had similar issue & this is what i did.

Thank you for that Solution.
It fixed the Issue of my friends MS without other problems
I'll have to try and the oven methode again. My phone has started to really act up again.
I've tried to install new roms, wipe ect. and it doesn't help with the screen.
Have anyone tried to replace the digiziter? They are pretty cheap on ebay
My milestone started freaking out just an hour ago. No more warranty here but I'm not brave enough to do the oven method. Had anybody tried the Rice alternative?

'Moisture detected' followed by reboot

Hi all,
I've been having some reboot issues on my phone after I installed XEF Oreo.
From what I recall it was fine on BTU but whenever I get a 'moisture is detected' message it'll reboot itself displaying the Samsung logo. It will continue to do this a few times randomly every few minutes then stop, occasionally a few hours later throughout the day I'll get a random reboot.
I'm pretty sure there is no water in the device as it's not warm at all, battery life is fine (suggesting there is no short circuit inside) and the reboots are software controlled reboots, not hard 'crash/ black screen restarts'.
Has anyone else experienced this at all? I'm a bit reluctant to take it to Samsung as I recall they just charge you if they find out their product has failed due to crap water sealing.
Thanks
Additional info:
- Model # SM-N950F
- Never been rooted
- Phone has been in water maybe twice since it was released and I got it, only submerged in a sink, no high pressure stuff
- I've not restored from any backups
- I've not disabled anything
- Oreo was a clean flash, wipe, start from scratch install
- Phone has never been in a case but I look after my devices, few tiny scratches on the back as to be expected, never been dropped, no damage etc
the moisture detected problem is a known issue ans nothing to do with Oreo, it also happens on phones that have never been near water (happened on my first Note 8)
best option is to do a backup first and then re-flash the phone using Odin

Is the restart problem known as well? I know the moisture is relatively known on the S8/S8+ etc but that's just a moisture message displaying all the time, I couldn't find anything on reboots?
Same thing for me every time I wash my phone.
Reboot on moisture detection.
IMHO that's just a bug, let's wait for a fix.

I have seen some reports on random reboot but not a lot, I would just do... backup-factory reset-reflash then it can't really be done cleaner, it's an annoying thing to have to do but sometimes it is just the way to go
I got it too after Oreo update. Phone has never been in water. Just used a hairdryer for 30 sec and it dissappeared.

It's such an annoying bug. I hope it's fixed soon.
Another fix is to plug in phone then power off while still charging....wait for the phone off charging animation and then reboot the phone (still plugged in).
Message should be gone now.

Just complete April's update ...CRD2
"Moisture reboot" still exist.
Try cleaning the port with alcohol & a brush, then blow out with compressed air. Also check for signs of corrosion. It probably detects a short or resistance for the moisture error. Even just dust can cause a change of resistance across pins.
I've never had this moisture error & reboot on my Note 8. I have encountered the moisture error but it was due to a specific usb-c to micro usb adapter & using a micro usb card reader. My Note 5 started to get corrosion/oxidation on the usb port to the point where it wouldn't charge anymore. Had to scrape off the corrosion with a dental pick & it started working fine again. On my Note 8 I now have plugs on my usb-c & headphone jack, I rarely use them anyway.
Moisture can be collected by condensation, if the enviroment is cold, as in air conditioned enviroments, and you take the device outside, condensation forms on all surfaces, including the usb port
I did a factory reset and Its been about a week, Haven't had any reboots since
Update:
I've since factory formatted, gone into recovery, cleared cache, wiped device, no change.
Flashed latest XEU (for my region) and the same issue persists. It's fine in water then moisture detected pops on the screen, followed by a reboot.
Device behaves fine apart from that, pins on charger look fine, no loss of battery, nothing has stopped working, just this stupid motion detected + reboots.
This is really annoying me now!
I lied in the above statement. Things were fine for about a week and then I'm getting random reboots again. What a pain
My problems started after the oreo update. When the phone gets wet and the " moisture detected" notification comes up the phone starts to reboot randomly.
Last week i did a factory reset and the problem is still here.
I hope there is a solution for this problem because it's starts to annoy me.
Samsung know about the issue
My galaxy note 8 kept saying moisture detected and would not turn on once it ran out of battery as it would not charge due to moisture detected. Took 2 days of continually reseting and then trying to insert charger. Which eventually worked.
Samsung UK said it was 2 different issues and sent phone off to have mother board replaced. That was about 3 months ago.
I now have moisture detected followed by reboot issue.
I will be going back to the store and be demanding a brand new replacement handset.
A near £1000 phone should not have these issues and it does not give me confidence in Samsung going forward

My Note8 was moistured many times in the swimming pool.
There was NO reboot issue when it was on Android Nougat (7). Just warning and "drop" icon?. When the usb port dryed, ? just disappears.
After it was updated to Android Oreo (8) and water ? detected, warning shown and phone restarts by itsef. The phone works perfect and no issues even in the swimming pool. After I dry it, so no more moisture, the phone reboots itself once again. Also no issues after that.
It was new firmware update (April) and reboots still happens when ? detected and dryed.
So I truly believe that it is software bug ? and hope it will be fixed in May's update.
P. P.
For people with moistured usb port and low battery - wireless charging works always even when phone is off/empty!
Same problem here but I've noticed that it only happens using the Samsung white fast charge socket, when I plug it into an old generic USB plug, it's fine. So I'm thinking it could be an issue with the fast charging adapter? I've tried disabling the option in the settings menu to no avail.
Update:
If the phone is in "Ultra Power Save" mode, the moisture detection do NOT restart the phone.
So it is SOFTWARE BUG for sure!
I get this exact issue with certain custom roms.
Weta rom was the only one not causing it.

Reboots & Shutdowns w/ Fingerprint Scanner

Hello,
Recently I have been having issues where my Note 9 would randomly restart every 5-10 when left on standby. It never happens when the screen is on. I've tried safe mode and a factory reset to no avail. Finally, I switched my screen lock type to pin, and poof. Problem gone. Tested multiple times and the fingerprint sensor is definitely the culprit. Any reason why this is happening? So odd...
Faulty hardware possibly. Factory reset to exclude software as the cause and if not return to Samsung for repair

xda members should be getting a portion of Samsung support employees' salary for doing part of their job for them.
I had the same issue this last week. Safe mode testing and restarts. Cache wipe and restarts again. Factory reset and good for two days. Put fingerprint back and 2 hours later I'm back on the reboot loop and after a day of Google I came across this post. Disabling stopped me from throwing the phone across the room today. This is weird, but disabling fingerprint unlock fixed my problem.
note 9 bootloop because of fingerprint scanner
I was constantly in a bootloop when screen would shut down. I tried every suggestion from, wiping cache, hard reset, safe mode, etc.... I diabled my fingerprint scanner and have not had any rebooting at all, my phone is under warranty and they are sending me a new one. Kind of upset about getting a new phone, but i will get over it. I contacted at&t and informed them of the problem and the resolution and the fellow on the line was very happy that i brought this to their attention. I hope i can help someone with the same problem.

The fingerprint scanner on the Note9's and S9's do seem to not like moisture. I powered my Note9 off, and rested it on it's screen on a flat surface.
I then took 99% rubbing alcohol and a Q-Tip and poured drip-sized amounts of alchohol on the Fingerprint sensor. I wanted to make sure the fingerprint sensor was neatly dressed in the alchohol and allow the alchohol to dry there.
Waited about 15 to 20 minutes and then powered the phone on. Set the fingerprint scanner to unlock the phone, and tested this 3 days before posting here. I no longer get random reboots.
Issue fixed.
If you try this yourself, make sure you use 99% alchohol. 70% has water mixed in which the sensor may clearly not like if the issue is really moisture getting in the sensor.
I tried this after seeing another user in another forum claim that he used rice to fix his sensor rebooting issue. Rice works but it takes longer.
Do this at your own risk. Good luck.
I am having the EXACT issue here. Random reboots/power off when the phone is on Standby. I disabled the fingerprint unlock and the problem is gone. That's the culprit for sure. Safemode, nothing works. I types *#0*# in phone dialer and tested the fingerprint sensor. Everything passes except for a test item called RESET and the test shows FAIL. So this is definitely a hardware problem. I am trying the alcohol fix now to see if it works. I have never submerged the phone but I have wiped it with a very damp towel for quite a few times because it is supposed to be IP67 water proof. This should be Samsung's problem. If this does not work I guess I will have to send it in for warranty repair.

SO I tried the alcohol solution. It did not work right away. The test still showed a FAIL and the phone would still reboot randomly while on standby. BUT IT WORKED THE MORNING AFTER! I am not sure if it just took it's time to dry. But I had cleaned the sensor with damp cloth before and it never had this rebooting issue. Well I guess this solution works. Definitely worth a try.
Thanks!
I had to eventually get my fingerprint sensor replaced for mine to work. They're only $15 on amazon. I recommend looking into repairing it yourself if you can. You would need an embossing heat gun, a ring suction cup, and some nylon picks to help hold it open. You can usually buy a decent kit for <$10 (- the heat gun). Also be prepared to ruin a deck of cards or purchase a metal phone opening tool. I like using cards because they're thin enough to get underneath the back plate, but thick enough to leave a gap to get my nylon picks in place. They also don't damage the shell like the metal opening tools can. The fingerprint sensor is probably one of the easiest repairs you can do, and the worst that could happen is that you break the back plate of your phone, which buying a new backplate+sensor is still cheaper than sending it in for repairs. You can buy some B7000 adhesive to put the backplate back on. Or just reheat the old adhesive that's already on there. Just be careful with it around water once you do this. Repairing your phone breaks the seal that was on there, so it's not as waterproof as it once was.

My Pixel 5 malfunctions after getting wet

Everything start failing after getting wet in a heavy rain, so it's not water resistant.
It seems are software errors. I did a factory reset and still the same, so maybe is about the hardware, but I don't understand why or how. Sorry for my English, I need some advise, those are all the errors I have:
- The music cut every 5-6 seconds in videos and music.
- Many apps crash and need to close like System, or any other app I'm using like Chrome, etc...
- Slow when turn on the screen with the button.
- Slow when unblock with the fingerprint.
- Slow when rotate the screen.
- Slow when I open the camera app.
- It doesn't recognize double tap in the screen anymore.
- I can't use calls, the app closes all the time.
Yeah, I think so, actually I went to the most recommended phone repair shop in Bangkok and they told me they don't fix Google Pixel, they told me that is not very popular in Thailand. So I'm thinking to go to another shop, but I think is not easy to fix a Pixel in this country. Thank you for the advise.

That's weird man... did your phone have cracks/been dropped many times before? Cuz I have literally swam with it (not intentionally , I'd just forget that it was in my pocket) at my building's pool many times and have kept it inside the pool for a few minutes and it's still working fine. I have the impression the phone is sealed pretty good. And it's still working fine after a few months.
The only error or malfunction I ever got was that the USB port has debris/water in it. But once I let it dry for a day or so, the phone continued working fine

Thank you for the reply.
Actually no, I didn't have any cracks/been dropped many times. I don't use any phone case, and looks good, it has almost two years already and the phone looks really good, some little scratches and nothing more. I mean, it was working very well until this heavy rain, and since I thought it was waterproof I recorded a video of the heavy rain, I was going in a motorbike. And after that is not the same anymore. I thought maybe with the factory reset but no, still the same. Maybe is the memory, or motherboard, or I don't know, I'm not expert about this technical things, but yeah, I think is quite weird.

Reason I ask regarding big scratches/cracks/or being dropped - it affects the sealing of the phone and things could get out of place and if not sealed properly then water flows in. Hopefully you get it fixed
