Question Proximity sensor not working - Xiaomi Mi 11 Ultra

Hi Everyone,
I was testing device underwater for 2nd time, first time it went alright with 0 damage and stunning videos. this time I went a little deeper and now phone is foggy and with dead proximity sensor.
After taking sample video for underwater for 15 seconds, I took out the device and dried it straight away, but water of course got inside, and after a few hours I started noticing fog on all lenses, front and back.
first thing I did is put it in plastic bag, device was on with no issues, I started to see slow performance like device went back to 60hz or lower, but was good. while the device was in the rice bag, I started heating the device on a very low temperature to enhance evaporation of moisture in device, and helps rice to absorb faster. which went alright, or as I thought. and I had no more moisture on the lenses.
later, I had to use the phone, so I had a phone call and phone screen was blinking all the time like it was working and not at the same time. then it worked fine. another phone call the device blinked green and turned off, and when I try to test camera app same happens (not all the time, once of 3 tries phone freez for 3 sec's then blink green and turns off). so I put it all night long in rice bag, in the morning I woke up to find more moisture on the lenses, and when I have a phone call, proximity sensor not working.
using CT test, proximity sensor is stuck at 5.0 and doesn't go to 0.0 at all, tried in safe mode, restart, phone calls, nothing helped out. now I got moisture absorber and will leave device in it for days, and see what will happen. hopefully it works back again.
in order to increase process, I am thinking to put device and moisture absorber in oven in a closed container at temperature of 60-70C for a few minutes to help absorbing and speed up process, I am not worried about 70C up to 90C of temperature to damage anything in the phone as long as it is turned off, and turned on after cool down. what do you think?
Any advise would be greatly appreciated, please help me with this stupid mistake.
for the people who want to make fun of me and blaming me for trusting IP rating, thanks in advance and much appreciate not commenting here. because I am frustrated enough and do not want any more stress.

IP68
Unlike the Mi 11, the Ultra model has an IP rating for dust and water resistance: IP68 signifies that it is 'dust tight' and can handle immersion in up to 1.5m of water for up to 30 minutes

Time to go to repair center

I've put the device in moisture absorber (calcium chloride) in a plastic bag with nearly vacuumed and opened Sim tray to give a decent air leak. And I put it in the oven at defrost temperature ( that I can leave my hand under without any damage to my self and not feeling burnt) for 15mins, then I turn it off for an hour but I leave the device in the oven, then again and again, and left it in the oven (oven turned off of course, but to hold temperature as long as possible) all night long, woke up with a very dry device (even underwater videos are now without water ) . Proximity sensor still not working. I used device for 3 hours and then suddenly I got a phone call (do you believe it?! ) And violaaaa sensor is working again
Device is working like brand you again, no issues at all, no water marks or dust on camera lenses, no faulty sensors, nothing at all.
Thanks god it went alright, I was losing hope and even contacted dealer and a few repair centres.
Lesson learnt, NEVER TAKE VIDEO SHOOTS UNDERWATER AT DEPTH OF 1.5M,,, JUST 0.5M,,,,,
Kidding!! Above water photos are amazing enough to enjoy with, no more underwater shooting.
Glad that I can smile and give some jokes again

[Q] Samsung Captivate out of washing machine

Hi Guys,
My Samsung Captivate got washed in washing machine and then in dryer for 1 hr. I turned it on and luckily, everything seems working except wi-fi and bluetooth are not turning on. It says "unable to start wi-fi".
Does anyone have any suggestions? Thanks a lot in advance!
That's pretty crazy... Extremely surprised it works at all. Pull the battery and open it up as much as you can and sit it in a bowl of rice for a couple days in hopes that the rice will absorb any moisture that might still be inside.
You probably should have waited awhile before turning the phone on. Take the advise of the guy above and try to continue to dry the phone out. It's going to take a few days, but it's your only real option at this point.
Also consider you might have did some damage already by turning the phone on with it still being wet...
You would have been fine with just the washing machine, but the dryer most definitely caused heat damage - which in my opinion is worse than getting the phone wet.

[Q] Another Water Damage Thread

Howdy,
Long version:
I left my galaxy note on the counter in my kitchen which is apparently not quite level. Overnight water pooled under it(never submerged, even partially). I did not notice until my alarm went off the following morning. As of this time it was still functioning properly. I moved it, wiped off the water. Took the protective case off and wiped the water off it was well, hooked it up to the charger and went back to sleep. 15 minutes later the vibration function went nuts while it popped up complaints about low battery. I say the vibration went nuts, because it wasn't the sustained vibration like you normally get it. It would cycle on and off about every half a second. I panicked, turned off the device and removed the battery where I noticed that the battery was wet, and under the battery as well.
So I wipe it off, put in a bag of rice and go back to sleep. Approximately 15(yes, way too soon) hours later I pull it out, put the battery in and turn it on. Works fine. few hours later I hook it up the charger and it immediately complains about the battery temperature.
Short version:
Phone at in a pool of water for 5+ hours, never fully submerged. Basically if you poured water on a level surface and sat your phone in it, thats what happened.. Anyways Water worked its way inside the phone(based on disasemble that occured later), and started vibrating randomly. took out batteyr and left in rice for 15 hours. Put it back together attempted to charge, phone complains battery is too hot immedately.
Observations:
I take out the battery and disasemble the device down to the point where the circuit board is separate from the display.
The far right ( +) connector that touches the battery appears to be slightly corrodeded. I rub it with a cotton swab to clean it. From watermarks it doesn't look like anything else got wet and by now its completely dry. I don't see any 'red' spots or stickers, but I'm unfamiliar with the water damage indicators, and the information i found from searches was innacurate(no white dot on top of battery, no red marks anywhere on it)
Panic
I put it back together try again, same deal. The phone doesn't seem to have a way to view the battery temperature reading(*#0*#), so I downloaded an app called 'Doms diagnostic tool' which indicates that the battery temperature is pegged at 80 degrees C and it does not fluctuate. I don't know if this app is actually reading anything though.
Can someone who has a working phone try this out? App is free.
Is it worth putting it back in rice even though its dry even on thorough dissemble?
Any idea how to get legit data from the sensor to verify if its shorted out etc?
Would a replacement battery with out the sensor resolve this issue?
Anyone have pictures of where water damage indicators are?
I searched thoroughly and found no answers besides taking it to a service center. Since I'm in America, and this is an international phone, I don't believe the manufacturer will honor the warranty even if the phone shows negative for water damage. My service is ATT, but I bought the phone at expansys( i think).
best at this point is to check your insurance, if its covered. In some countries I read this is covered as it was accidental.
I would recommend goong to samsung and let them check it, with the true story ofc. Now if they find whats wrong, they might be lenient, or not. Anyhow then you know whats broke, and you can decide to fix it for yourself or have it fixed. At this point it sounds like corrosion on one of the boards, or shorts somewhere.

[Q] Water damage. Droplets inside camera lens and flahs

Hi, I have owned a ZR for about 8 months now, Today I took it in the pool for the first time (after checking the flaps and back cover) for 5 minutes (not continously). It worked fine after I took it out of pool (cleaned it with fresh water after getting out of pool as well). However, after 3 hours the phone didnt turn on. I removed the back cover and there were water droplets inside (all three LDIs had turned red). After closer inspection, I also noticed that there were droplets inside the camera lens and flash
- I dont have access to rice right now (will have it in 12 hours)
- I have put my phone (battery, SIM removed; all flaps opened) under a light to 'dry'
What are the chances of the phone being able to recover? What should be my next steps ( After drowning it in a bowl of rice of course)

It has been submerged in a bowl of rice for about 12 hours. How long should I give it before trying to turn it on again? What could be any signs that it is not fully dried yet...?

You need to keep the phone 3 days there.I hope its not too late.Than take it out,put the battery and try.
OMG You saved me from thinking that the flaps are the only reason for water leakage in the phone
If you want something more effective than rice order some calcium chloride flakes (you can get it on ebay). It's the same principle as rice but is far better at absorbing moisture.
Currently have the same issue, I contacted Sony and they told me to go the the nearest service center. Mine started when I accidentally dropped my phone around 4ft high
this same thing happened to me, droplets on the front cam and back, even the sensors has droplets, but to my suprise my phone runs perfectly. i dont know what happened. took it for a swim, after an hour droplets showed. i just opened the flaps and in minutes the droplets was dry.

[Q] Can re-soaking fix water damage?

I know it seems like a stupid question but I've got nothing to loose at the moment so I'll explain my situation.
About 3 months ago I took my Xperia Z1 for a swim in the pool to see how the camera performed underwater. The screen started to go black when I took it out and then it completely shut off. I took it inside and turned it on again. It lasted a minute before shutting off so I plugged it in to the charger and got the boot logo before shutting off again with nothing: Screen was off, no led, no vibrations, nothing.
I opened the flaps and they were still white and still are today and there was no moisture or anything. I tried plugging the phone in a few days ago to see if it still works and the led turned on and it just stays like that with no action. Left it for a few hours but still nothing.
I don't really need this phone anymore because I have a Z5 now but a second handset is always nice to have. The pool water would have had a very small amount of salt in it and I think that might be causing issues. Either that or there is still water in there (unlikely) or parts have rusted or even the phone might have got shocked when I plugged it in to charge. What I was thinking was opening the ports and soaking it in water for a minute or less and then taking it out and putting it in a bag of dry rice to drain the water out of it. I'm not sure if it will work but I haven't got anything to loose so I was wondering if it is even worth giving a shot or even some tips would be nice.

Resoaking your phone will help as much as trying to jump from a cruise ship in the middle of the ocean for the second time and you can't swim...

To clarify, the Xperia Z1 relies on closed ports to ensure waterproofing. So soaking it a second time would destroy it further.
there is a easy way you can try.
buy some electrical contact cleaner from a computer shop or maplins etc, spray that all over the circuitry and contacts and scrub it off with a paint brush, there is a good chance it will work again as it will remove any corrosion casued by water, ive repaired hundreds of water damaged phones this way and it doesnt need any special things.....

My Note 5's screen stopped working after water damage , can hear sounds , any help ?

Just a few hours ago while riding bike Suddenly rain started and My note 5 in a pocked soaked little bit, when I stopped I cleaned it with cloth it was working fine till half hour but when I came home the screen flickered and went Black. Notification LED and sounds are still working, I tried to shut down the phone by pressing and holding power button but it couldn't for some time, it restarted twice in between that, I can tell by sounds but I think it's off for now. I have kept the phone in a rice bowl . Is is possible to my phone and phones screen work properly ? is there any other way ? I saw in one video that we can put it in isopropyl alcohol 99% for half hour but I am unable to get it . Please suggest me if there is any solution ?

1)Power Off Your Device And Use Hair Dryer To Dry Off Possible Water Gathered at sides of Edges And Display Corners
(Dont Hold Hair Dryer Much Closer To Device As It Will Probably Damage Internal Circuits, Just Hold It At About Secure Distance From Device)
2)You Can Also Try To Put Your Device Below lightening Electricity Bulb To Dry Off Water
(Especially Orthodox Bulbs Which Lights Yellowish In Colour Which Produces Much Heat After Lightened For Long Duration, Here also Hold/Keep Your Device at secure distance to avoid internal damage to device)
Note :-
Be sure to keep your device turned off and don't try to charge it more as it will cause internal circuits damage due to water reactions with electricity

Unfortunately you got water into the charging port and it caused a short circuit breaking the screen/LCD.. You're pretty much going to have to replace the entire screen/LCD.. Right now your best bet is to put it back in the rice for at least 2 days and put it in the plastic baggys that you can buy so it sucks the moisture out of the device.. Seems to me like your screen is done for though..

my device started successfully- screen, touch was working but it was flickering a bit in the top side, I immediately power offed device and put it in rice. so I am positive it will work, i have ordered isopropyl alcohol 99.9%, I am goin to put phone for half and hour and then put again in rice for 2 days , what you suggest ? isopropyl alcohol won't damage right? ive seen video on youtube thats why I am thinking about it .
I saw in this video what you think should i do it ?https://www.youtube.com/watch?v=sqolv4Ofsrc&t=609s

No like I said leave it alone I've done many of these repairs and if you keep powering it on before the water is fully sucked out by the rice you run the chance of poping a capacitor and then it will not be able to even charge and about the alcohol I don't recommend that unless you can find 99% rubbing alcohol because if you buy 50% rubbing alcohol you are going to be adding 50% water in again with the other 50% alcohol.. 99% means 99% alcohol and dry super quickly but there's still that 1% percent water in there! The bag in the rice trick can do the trick if you didn't short circuit nothing on the motherboard but once you short circuit the board it's not easy to fix at that point without proper tools.. Leave the bag of rice like in the sun for a little while too like inside of a car because that will help evaporate the water and the rice will suck it in..

new update - took phone out of the rice again , it booted up well and worked without any issue for a while but again screen went to black . after few attempts , phone started working normally , but this time I powerd off device and kept in rice again. when display was on it didnt flickr , touch was working good.so when its on everything is working perfect but display getting back to black in sometime. what u think , there is still water ? isopropyn alcohol i got is 99% pure , but I am afraid of doing it as my display is working atleast for sometime ,so I dont want to risk anything . my bet is on Rice , and its raining heavyly here , so no sunheat . I thought of drying it by hair dryer but its hot air dryer .
*how long should I keep it in a rice ?its already 36 hours.
Phone is working fine now.Thanks for replies. Rice did the work.
