Z3C temporary dead?

So I got my Z3C about a month now. 6 weeks ago I thoughed my phone broke, suddenly it was dead. It looked like it was bricked, but I didn't do anything with it. There was no charging light, no fibrating on a hard reset, nothing. There was not even a connection with the adb.
So I send it to a repair point and they fixed it for me. I had no idea what that do, but I was happy with it.
Yesterday it happend again and I was pretty angry. A 3 month phone broke twice! I contacted the store, because I want a new one and not another repair, because i have no faith in another repair.
Now here comes the thing. Today I tried my phone again and suddenly it was working again.
You might think I should be happy, but I'm absolulty not, because now it is hard to prove there is something wrong with my device.
I suspect the repairpoint didn't fix anything, because it was working again at that point. So they just did a factoryreset
Has anyone experienced something like this or has any clue what the problem is?
Thanking in advance.

first of all you should make it clear If it s software problem (which level of software) or hardware
to get this u can Repair Xperia firmware by PCC to install fresh firmware
after that if problem remains u can be sure that problem is in hardware and ask for replace
in repair center they may just install new rom and return it so just ask for replacement
:good:

I k now this post is a little old but I have the same problem. After 6 weeks of flawless use my Z3C suddenly died. Nothing would bring it back to life. I spent several hours on the phone to sony support to no avail. We tried numerous manual and computer related fixes to no avail (including flashing a new stock rom which didn't work because no phone could be detected). Finally the tech gave up and said to return to return it to where I bought it. I was in the process of doing that when suddenly the phone worked again when I pressed the power button. battery charge was showing as 74%. Unfortunately I didn't do a factory reset while I had the chance.
This afternoon I didn't use the phone for 3 hours and now it's dead again. Nothing will wake it up again.
To me it sounds like a hardware fault, not software. This is a near new phone. This shouldn't be happening. I've searched the net and found numerous others having the same problem and in every case it has resulted in a replacement phone. Unfortunately my phone seller is a long way away. I guess that will teach me to buy local and pay and bit more.
Any suggestions please as I'm desperate.

I'm also in the same boat where my g/f Xperia Z3C just died and unfortunately the phone is out of warranty as it was a grey import and not local Aussie stock.
I have tried everything to get it working. When it does switch on it doesn't last more than a few hours before it goes back to a permanent coma.
I've wiped the rom and started from scratch when it was working with the Sony Xperia Repair centre but with little success.
I was left with little choice but to take it to a repair centre to find any faults with the hardware but I'm not feeling that confident they can fix the phone without replacing the whole board which isn't worth it.

Same thing.
Hello,
Today my phone shut downs itself and i realized it after 2-3 hours.Can't force reboot with volume up + power or the yellow button near the sim slot.Also no leds working to confirm if it takes electricity or not.My phones screen changed about a month ago due to having volume changes in 3.5 mm jack while listening music.Funny thing is i gave my phone for that same reason 8 months ago and they did not changed the screen and when i asked why you changed the screen, the lady said because 3.5mm jack is together with the screen(which i do not believe).I am hoping for device to wake up like jesus...
Edit: Does android have a log that reports every incident like windows does?If so how can i access it to see why my phone decided to die and ressurected by itself?I can't get this device to technical service cause it is fine now but i want to make sure it does not happen again.

[Q] I have replaced my screen twice but the touch screen stops working after 24h

Hi friends,
A week ago I decided to finally replace the cracked screen of my phone. The phone was perfectly working, with the exception of the annoying lines everywhere around the broken glass.
I went to a repair service (not official) to have it changed for a new one (glass+lcd) and got it back repaired after few days.
During the first hours the phone was working just fine, but I noticed that the touch screen was slowly getting erratic. After few hours it was just a bit erratic but ok. 10 hours later it was almost impossible to use already. 24 later it didn't respond anymore to the touch.
I went back to the repair service and asked for a new screen that I got for free because we assumed it was a problem of the new screen. Problem is, it happened exactly the same with the second one!! And now, 24 hours later, it doesn't work anymore.
I have done a factory reset. I have flashed new ROMs, I have flashed back to the stock ROM, updated it, nothing has changed so it totally looks like a hardware issue.
My question is:
What may be causing my new screens to go mad after working perfectly fine during the first hours?
Summary:
My Moto G 2014 works perfectly, but it has a crack in the screen
Decide to go to a non official repair service to have it changed for a new one (LCD + Glass)
First hours with the new screen: All works fine
Slowly, the touch screen becomes more and more erratic
24 hours later the touch screen is useless (it still reacts to touch but totally mad and weak)
Decide to have it replaced again (this time for free)
With the second new screen, we test that works fine, and to confirm that is not the phone, we install back again the first new screen, verifying that it doesn't work.
Finally install the second new screen. All seems to be perfect!
Experience again all the previous points
What should I do lads? Did the repair service **** my phone? ;^(

It could be that water somehow got in (speaking from experience).

How would that explain that the newly replaced screens work fine for the first hours and then gradually stop working?. Also , I can't imagine how water got in the phone for the last weeks, besides, it works perfectly, is just the touch screen.Water would most likely **** more things. no?
Has anyone experienced the same problem as me?
thanks!

Is it genuine?

The screen? I don't actually know. But after changing twice the LCD seems unlikely that the LCD was defective. It may be more related to my phone (although I can't understand what) and something the guy of the repair service ****ed.
Any thoughts?
thanks for the help

Main camera replacement problem

Hello, i have following problem with P10 camera:
Model VTR-L29, Firmware VTR-L29C10B120.
The focus in the main camera ceased to work. There was no way for me to apply the guarantee, so I have disassembled the phone and tried out three new replacement cameras from Ebay (Index Sunny B1730 and Sunny B1737). All do not work: the camera App immediately closes, other photo apps says that the camera is not found or is busy, AIDA64 does not find the camera too. Factory reset and cache delete has already been done several times. Several times I tried the original camera again and it worked (except the focus), but after I tried B1737 it stopped to work and now shows the same symptoms. Before the original camera stopped to work the camera App worked even without a camera and showed a gray screen, now it also turns off immediately. Maybe someone has an advise for me, thanks and sorry for my bad English.

hello;
first excuse my english i know its bad; please replace your original cam and for repair the focus juste tape on the frontal cam with your finger joint between 5 to 10 times not so hardley
i tray this it work 100/100
please share with others personne hou have the same problem

Another user had the same problem with the focus on his phone after he dropped it. He fixed it very simple.
Pick a place in your house where you have carpet on your floor. Now put the phone on the floor standing on the usb-connector. Push the phone over so it falls on it's back. Use you finger to keep it from bouncing back.
He said the focus worked after this procedure.
Good luck!

It's really works. Thank you. But this is just a temporary solution. I wonder if we replace with the original part (at authorized service centre) it will guarantee the problem will not occuring again?

I had the same problem a month back after my phone fallen on the floor from my pocket. The camera could not focus and blurry picture quality. I tried everything I found in YouTube or any other forums but all are temporary solutions.
I then contacted Huawei Customer care and they changed the camera and delivered the phone same day. My phone was in under warranty period.
Its fixed now and working fine.
I think you need to send the phone to Huawei Customer care

Problems with water for my MI8

So just to make the story short.I was running 3 days ago with my phone in my pocket and i noticed some sweat in both front and back cameras. Phone restarted.I closed the phone , when i got home i left the device close to a heat source +some periods in rice . Today in the morning phone managed to load OS for the first time . The problem now is that the display does not respond to commands. Other things seem ok , just that screen is not reading the touches. Can i save the touchscreen or should i forget about the phone ?

This is usually an indicator of corrosion that has developed sonewhere (usually in the contacts of where the displau's flex cable connects to the motherboard). You can try letting it dry for more time, but usually it's the end of the road I'm afraid.
There are 3rd party shops that can offer to repair it (pro shops use an ultrasonic cleaner), but this is always a 50 - 50 thing; the phone may or may not work, and if it does, it may work for weeks, months, a year, etc. Nobody knows. If you're just going to put or throw it away, consider trying to take it apart yourself, grab a tooth brush and some 99% isopropyl alcohol and cleaning away any corrosion you may find.

Pixel 5 multiple sensors and software issues

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,
