Hello,
A week after I purchased my Galaxy Note 2, the back camera has stopped working. Now, each time I start the Camera app, it says " Camera failed " and FC.
Is there anything I could try to do to try and fix this issue?... as I do not want to send it back for servicing. Same thing happened to my Galaxy S a while back, but a restart fixed it. Now it does not do anything.

You might try a data/factory reset in settings, backup and restore. Backup files first as your internal memory will be wiped in the procedure. If that doesn`t work reflash your rom with Odin, see here for how to http://forum.xda-developers.com/showthread.php?t=1896696, DO NOT USE A PIT FILE WITH ODIN

Sadly, I'm going to have to send it back for repairs as nothing managed to fix the issue.
It just sucks that after just 2-3 weeks it breaks. Oh well...
What do you solve with camera? I have now the same problem with my galaxy note 2.

I too have the same problem and local service center won't accept it since purchased overseas. Anyone found a solution? How can I check if the camera firmware is ok? Whenever I try to go into the camera secret menu by dialling *#34971539#, I get an error that the application Factory Test has crashed unexpectedly and it FC. Does this point to the software issue? Using stock firmware "XXDMA6_N7100OLBDMA4" and non rooted. I have even tried opening the phone and checking for loose connection for the rear camera module flex cable and re-seating it but problem still persists. Front camera and all other functions work fine. When start the camera application, it FC. Other 3rd part camera applications also come up with an error.

No, I am still looking for a solution. Do you have any files in the 'system/etc/firmware' folder of the phone? I believe that is where the camera firmware resides but it is the phone firmware and not the camera firmware. The camera firmware will be updated with the phone firmware if you select the 'phone to cam fw write' function. There should be a firmware residing on the phone module itself I believe and this is what is reported as the camera firmware version.

I fixed my problem by buying a new camera module from the service center and installing to my phone. After checking the boot logs for my phone, I noticed that the camera module was not initializing and figured it was a hardware problem. That is also the reason why the cam fw could not be read. Cost me ~ USD30 to buy a new camera module with self installation for my note 2.

Though it is pretty late, I need your help in reading the boot log to understand if the camera is failing to initialized while booting? I've dropped my note 2 yesterday and since morning the primary camera is not working.
Kind Regards,

A battery pull made the camera work again!
Hi,
I apologise with you for my English xD. I bought this product one month ago and I have seen that the phone, when switch to the edge mode, have the soft touch back key that stuck and make the phone unusable. I've tried to switch firmware from base (portougal) to German without any result. Also randomly the network cut off or go in emergency mode (I've changed two micro sim). How can I do to resolve these issues? The new France firmware can resolve? It's a good decision to send the phone in guarantee or can I install a cooked rom to try?
Thanks at all

Hi bro... I think you need to perform Factory reset .
Setting> Backup and reset> Factory reset.
It seems to me pure Software issue..
Hipe it solves your problem.

My problem is that i was running stock 4.1.2 and IMEI and everything was working well until i flashed a custom android 4.3 rom and lost IMEI.. i tried to flash some modems and then got it back but still had the problem of not registered on network.. i tried to get back on stock and i also had "not registered on network" but IMEI is good... so my question is why installing a custom rom causes this ?

Hello everyone,
I bought a few weeks ago from amazon this phone: LG G4 H815 5.5-Inch Factory Unlocked Smartphone (Metallic Gold) - International Stock (No Warranty)
I know it says no warranty but I have to try. The thing is that yesterday, out of nowhere, the camera stopped working. Whenever I open the app it shows the buttons but the screen remains black. After a couple of minutes it shows the message "Cannot connect to camera".
I tried the following without success:
-Stopping the app and clearing the cache and data
-Rebooting in safe mode
-Disabling Nuplayer in the developer options
-Factory reset
Please help.
Thank you!!
Hi sorry for your problem . I have the same one . Have you resolved it and what was the problem ?

Hello,
I've bought my Xiaomi 12X in May 2022 and for a couple of months I was able to use it without any issues.. After a while I started to get random restarts , in different apps , in different periods of the day in different conditions ( wifi , 4g , bluetooth , etc.).
I've contacted Xiaomi they told me to perform a factory reset. I've done it without sucess.
I've tried already different ROMS ( MIUI 13 and MIUI14 dev) and the problem is still persisting.
Does anyone have a clue of what could be happening ? Any troubleshoot that I can perform ?
Thanks in advance for your help this is driving my crazy!

If after doing all this and it's the same, surely a hardware problem, send it back under warranty.
Ok thanks for the quick response.
Before I send it back to warranty do you think I shall lock it again ( I've done a MI Unlock in order to install a custom rom...) . I'm afraid they won't accept my phone back because i've installed a custom Rom. What do you think ?

Normally this is not a problem but doing it, with the latest stock rom, it will erase your data.

Anyway before I send it back to Xiaomi , I was thinking checking the dump logs , do you know how to do it ? Or analyse the logs with logcat ? Do you have a procedure to do it ? I used to be programmer so I still have good technical knowledge

Especially for a software problem.
How to enable logging using ADB?
1) Settings -> My device -> All specs -> quick-tap "MIUI version" 7 times, until you see a toast notification that "you are a developer".
2) Settings -> Additional settings -> Developer options -> enable "USB debugging".
How to generate a log?
1) Download "adb.zip" and extract it anywhere you want.
2) Connect your device to your PC via USB.
3) Run "StartLog.bat" in the extracted folder.
* If an authorization dialog shows up on your device, click "Allow".
4) Reproduce the issue you're facing, i.e. if the issue is a crash in an app, open the app and let it crash.
5) Stop logging by closing the window that was opened by "StartLog.bat".
I use xiaomi.eu, so far I've experienced random restart two times. It was during phone calls. No idea why...

I think this random restart is related to hardware problem... Previously i owned a Poco x3 Pro, That phone also has this random reboot issue... I tried resetting & even flash Android from Service center..but it didn't solve the issue. So i raised complaint in service center and they replaced my phone with a brand new redmi note 10 pro and a MI band.
So i recommend to visit service center and claim your warranty...
Hi Guys, please help me here.. because i'm getting really upset with Xiaomi and I don't know what to do anymore. I've just spend 1 month sending back and forth my phone to Xiaomi service and the phone sent back with the same issue , they didn't even bothered looking into the phone. They just said : "Cannot reproduce issue". Well actually they just updated it to MIUI14 , but after a while the phone keeps crashing and reboot. Can you guys help me ? Is there a way to get access to the crash logs , I want to proove to Xiaomi Service that my customer is constantly rebooting ? Alternatively Is there any possibility to perform overclock (or underclock) i've seen some post claiming that decreasing the CPU frequency was helping with reboots . Any other ideas ?
Finding a workaround is not a definitive solution, tell them that you still have the problem, possibly make a video proving your statements.
Thanks for the reply , but any idea how to make a video of a random reboot ? I've thought about this several times but I just cannot find the right timing.. since I don't know when the phone is going to crash ... it's just crazy.. other than filming my phone ( with another phone ) for 24 hours I cannot find another solution...
How else to prove this problem?
The phone is guaranteed and may have a motherboard problem, it is not up to you to prove the problem but to them to find the fault.
I don't know what country you are from, but I know that the after-sales service for Europe is deplorable (under-contracted).
If you bought the phone somewhere other than Xiaomi, you should contact the seller and not Xiaomi directly.
I confirm that the after-sales service for Europe is deplorable , i'm in France and i've sent the phone to the after sales in France. They have done nothing with the phone ! They just sent the phone back to me saying 'issue cannot be reproduced'. I really neeed to give them evidence of my issue... do you know where are the crash logs stored in the phone ?
Surely this company, look at the notes:
ceat-electronique.fr est noté « Bas » avec 2,1 / 5 sur Trustpilot
Êtes-vous d'accord avec le TrustScore de ceat-electronique.fr ? Exprimez-vous dès aujourd'hui et lisez ce que 127 clients ont déjà écrit.
fr.trustpilot.com
Regarding the logs on the stock roms, I don't know, not sure that they are accessible by the user.
The problem is that in the event of an app crash you can send a report but in the event of an intensive reboot this is not possible.
Yes, that's the service center in France and I've also checked their reputation in trustpilot and also on google reviews , they are really really bad. Moreover that company is almost bankrupted. But... what can I do ? Do you know any way to escalate this at an higher level at Xiaomi ? I'm always stuck with Xiaomi support center...
By the way ,i was able to get these logs from the stock ROM ( powerinfoFile).

Who is the seller?Important
Send them these logs saying that the problem is still present, but given their reputation the task is difficult.
Even by contacting Xiaomi directly, they will refer you to this repair center.
Try an approved repairer or change the motherboard yourself, but it will pay off.
What follows engages only me.
What I would do if no reaction from them:
Short circuit via the USB port to burn out the motherboard, then say that the phone no longer works..
Whereas having a phone that works randomly is the same as no phone.
Straight or double.
A big risk given the reputation of the subcontractor.

Hi Guys,
I NEED YOUR HELP , my nightmare is not over.
I’ve sent my phone again ( this is already the 2nd time) for official repairing, this time in switzerland. ( i've attached all the logs prooving that my phone has an hardware issue , showing all the kernel panics , all the fault errors , etc.).
They have sent back the phone saying : ‘Issue cannot be reproduced’.
I don’t know what to do anymore, any ideas ?
Cheers.
