Ascend Mate 2 rear camera and flash not working - Huawei Ascend Mate 2

Model Number: MT2L03
Build: MT2-L03C00B322
Android version: 5.1
EMUI 3.1
Not rooted.
Not sure exactly what the issue is. I think it needs a new battery. Because when it gets down to 10% left it will randomly go down to 2% all of the sudden, then I will get that message saying "phone powering off" then the phone is difficult to ever get back on... which is why I try to never let the battery go completely dead.
Anyways the other night it went completely dead..... I charged it for forever it seemed, I noticed it was a little warmer than usual.
I ignored it and left it plugged in.
The next day I took it apart (I have taken it apart before, and put it back together with everything working fine)
Reason I've taken it apart in the past is because I had to replace the lcd screen because the other one got sat on and it shattered.
So I have an originally white phone with a black lcd screen....
Anyways I took the phone apart again, looked at the battery to make sure it wasn't bloated or warm anymore. It was fine.
I turned it back on and I noticed when I open the stock camera app it kept saying "can't connect to camera" or something similar.
So I took it apart again, unplugged the camera and plugged it back in, tried rebooting the phone, and when I opened camera again the phone then rebooted itself a few times.
Now instead of getting the message of "unable to connect to camera" it's as if the phone doesn't see the rear camera at all anymore.
The flash for the rear camera doesn't work anymore either.
I got it to turn on for a while, when it couldn't connect to the rear camera, but then it didn't want to turn off, then the phone rebooted itself, and now I can't get the rear camera or the flash to work.
The front camera works fine. But as for the rear camera there are no options to switch to it like there used to be.
On the top of the camera app there used to be a sort of "refresh" icon that would switch between the two cameras, that's gone though.
I also tried downloading apps that tell you about android hardware... and they say for secondary camera something like "not detected"
I made sure though.... the rear camera is plugged in all the way.
I even tried the backup and reset thing....
I don't know how to boot this model of phone into safe mode. I tried holding the power button, but I'm not sure if you hold the physical button, or long press the power icon on the screen???
I opened the camera app and went to settings and restored defaults.
I also tried opening app info for camera and clicking clear data. Neither helped.
How do I get android to see that there is a camera there?
Would downgrading the phone to the original build it was on help?
I think it was originally android 4.3.
Edit: So my main questions are... how do I boot into safe mode?
Would rooting it and clearing the dalvik cache work maybe? Isn't that what causes android to say "optimizing app X of X" when booting up?
How do I root this phone? After I root it would there be anything I can do to troubleshoot the rear camera or flash?
It just seems weird to me that one minute it says it can't connect, but the flash was working. Then the phone rebooted itself, and now it doesn't even seem to realize that there is a rear camera plugged in. And now the flash for camera isn't working either. Even did a backup and reset.

Touch screen not working.

Hi guys. I'm totally new to the android/smart phone world btw. Anyways, I recently got my Samsung Galaxy S2... first thing I noticed, my touch screen wasn't working. I popped the battery in and out and then it started working as it should.
My phone was working fine this morning, then all of a sudden out of no where, the touch screen stopped working again. I've tried turning on/off the phone multiple times. I've taken out the battery and even my SIM card nothing... i'm worried.
Has this happened to anyone else? Is there a fix? Do i have to go through Samsung? I hope not. Incase anyone asks, I did not root my phone.
Any help/feedback would be appreciated.
When the touchscreen stops working... were you charging the phone at that time?
The first time i turned on my phone, was actually by accident and it was charging.
However, just earlier now, it was not. it was just sitting on my computer desk. The home button, lock button and touch capacitive buttons work.... but i can't get past the lock screen
you could try a factory reset to see if its software related, but it sounds like hardware. I would definitely Return the phone .
I guess I can't do a factory reset, since I can't get into any of the menus... man this sucks. I spent $900 *gulp*
To do a factory reset,
1. Turn the POWER OFF, pull the battery out and put it back again.
2. Simultaneously press and hold the Volume Up, Home and Power button
3. If the Samsung Symbol appears, release the Power button
4. A Boot Menu will then show, Use the volume up/down to choose wipe data/factory reset.
touch screen not needed this way.
oo that's interesting... I tried it. and it didn't get to a boot menu. maybe I was doing it wrong. I tried a few different ways, but no success. It turns out I have warranty with the store. They're going to replace it for me Thanks for the feedback guys. Awesome forums.
Something similar happened to me yesterday. When I had the in-box USB cable attached to a BoxWave VersaCharger (combined AC/DC charger), and the VersaCharger was plugged into 120V AC, the touchscreen would stop working. As soon as I unplugged the USB cable from the SGS2, or plugged the VersaCharger into a 12V DC lighter socket, the touchscreen would work fine.
I've got the same problem as the OP... I had my phone charging overnight and this morning when I first went to use the phone I could not unlock the screen. I could wake the screen via the home button, and see I had a missed call etc but it just wasn't responding to touch. BTW I can't remember if when I first tried to unlock the phone if it was charging or not but really this shouldn't matter.... oh and btw, I'm not rooted or anything either! Naturally I rebooted the phone but still the same problem....so I tried a battery pull and still the same problem. Just now I did a factory reset but the touch screen still isn't working! I guess this is a hardware problem so I'm going to get it fixed under warranty by Samsung! Gutted that I will likely be without my phone for a week or 2!
EDIT, UPDATE...
Well, I was just on my way to the repair shop Samsung warranty had told me to take it too, and I took my sim card out to put in my old Hero (the only thing I hadn't tried!) and I couldn't believe it but the touch screen started working fine again! Weird, but that is now my advice if anyone else has a problem with their touch screen not working - oh and I took the sim out whilst the phone was still turned on. Crisis averted!
UPDATE 2
Sadly this has happened about 4 times to me now and I'm just waiting for the inevitable next time. Each time doing a factory reset then taking the sim card out seems to bring the screen back to life (though last time not immediately) but I shouldn't have to put up with this. Problem is, I don't want to send off a seemingly perfectly working phone to get repaired as I fear they will struggle to notice the problem, never mind fix it! I'm hoping a new firmware comes out soon, in the hope that it may resolve my issues...
Me as well ...
I have had this happen to me twice now (Touchscreen not responding).
The first time I had just installed a game and thought it must have been related to that. Pulled the battery and no joy, left it for a while and it came back to life...
Second time I was surfing the web and it stopped responding, pulled the battery and left it for maybe a minute but no joy .... pulled the battery again and left it for probably 20min and it came back to life. When it came back up I noticed the livewallpaper had been turned off and my widgets were gone from the homescreen.
What I did notice when it wasn't working was it had "safe mode" displayed at the bottom left of the screen
Have the Same Problem
Have the same problem i Mine and was super exicedat first it worked fine and after charging the touchscreen stopped working i pulled the battery out and put it back in but no luckso im gonna return mine to the shop hope they replace it
Moral:AT FIRST SUPER EXICTED BUT NOW SUPER ANGRY
Same issue - Is there ANY way to save my data before I send it in for repair/replace?
Hi all,
As of this morning, I have exactly the same issue as the OP. Screen doesn't react to touch, with the exception of the capacitive buttons. I found a dude on YouTube that had the same issue: youtu.be/0oIdllWiV4I
The last thing I did with the phone before it started misbehaving was to answer a call. The phone was on the charger when the call came in - I can't recall whether I unplugged it before answering, or after, or at all during the call. Not sure it has any relevance anyway, only mention it because I've seen reports of people's screens no longer reacting to touch when the phone is plugged in to a charger (apparently it even states in the manual that this may happen).
Anyway, whilst all my contacts, SMS, photos etc are backed up to the cloud, the same can't be said for my app data. Before I lose hours and hours of progress in various games, or all my settings in numerous other apps, etc, can anyone think of any way to get access to the memory of the phone, bearing in mind the following:
I can't connect to Kies to pull a back-up because bluetooth is currently enabled on the phone and when one connects the USB cable, it says "Activating USB mode will deactivate Bluetooth. Continue?" but I can't click the Yes button
I can't connect in USB mass storage mode because I can't navigate to the settings menu entry to enable it
I can't turn Bluetooth off in order to get Kies working, becuase I can't get to the settings menu or pull down the notification bar to reach the power control.
I can't use Voice input to control the device (on the off chance there was a "bluetooth off" voice command) because (presumably with the most recent firmware I flashed via Kies a few weeks back) for some reason Vlingo is no longer the app on the double-home button action. Instead it calls Samsung Voice and wants to walk me through a first use tutorial, but I can't click the next/skip buttons
I installed via Android Market push the app belonging to www_remoteaccessphone_com as it promises to be able to remotely switch bluetooth off, but the website says I haven't installed the app yet, presumably because alrhough I was able to install it without touching the phone, it probably needs to be run at least once to set it up, and I obviously can't do that
I can't start Kies Air to try and get my data that way (starting it would require using the touch screen)
Kies via bluetooth isn't supported on Android
Needless to say, the data I'm trying to retrieve is on the internal memory, not the SD card. As you can see I've been trying all sorts of creative things, but I'm fairly sure I'm screwed. Any bright ideas I haven't thought of?

flash it with CF-root, boot into CWM recovery, do a nandroid backup after that, use CWM recovery again to mount USB storage, connect to your PC and pull everything off.

Thanks for the quick advice. I guess I'll need to use my girlfriend's phone to download CF-root and then transfer the SD card to my device. Quick question before I proceed though - is it possible to remove all traces of such tampering, since I've already made out with Samsung that I'm sending it in for repair, and I'm not sure they will honour the warranty if they see it has been rooted etc.

get a USB jig off ebay or amazon to reset the flash counter. should not cost more than 5 or 6 euros, shipped.
anyways you need to flash CF-root through ODIN if you are coming from stock. instructions are all in chainfire's cf-root thread.
Nandroid Restore
So I successfully rooted, used CWM to do a Nandroid backup, mounted the sd_card and saved the contents (including the nandroid backup) to my PC, reflashed the stock rom & kernel, usb-jigged it to get the counter back to zero/original and sent the phone in for repair. My efforts paid off as they repaired it without question under warranty. I just received the phone back and today set about restoring my backup:
Copied the sd_card contents I'd saved to my HDD back onto the phone
Re-roooted it with Cf-mod.
Used CWM to restore the backup I took before sending it in
It restored boot/system/data/cache successfully
selected reboot now in CWM
The result is that it is still missing all my apps. It only seems to have the "data" like my camera shots and SMS messages, system settings like whether bluetooth is on or off, the volume level, Wifi networks etc. So something was restored. But there is no Google Account configured, the lock screen picture is the default not the one I had beforehand, and as I said, all the apps - the main reason I did this whole thing as my personal data is all backed up to the cloud on a regular basis anyway - have not been restored. Am I confused? I thought a nandroid backup took a complete snapshot of everything, apps included.
Finding out the list of Apps I had in order to reinstall them is not an issue - I have a list of everything I had installed saved on AppBrain. But if I reinstall the apps, all the settings (or progress in the games) within those freshly installed apps will be back to square one, not where I left them, right? Or should I reinstall the apps and then restore the data partition over the top again?
Are you guys using any type of screen protectors, cause if you are, that may be the issue s their have been reports that the screen becomes unresponsive with certain screen protectors when connected to a charger.
However, if you are not using a screen protector, then I would suggest getting the unit replaced as you should not have to do anything, root or otherwise, to get the touchscreen working on a touchscreen phone

Nope, no screen protector or any kind of case for that matter. Anyway, that isn't my issue anymore. The touch-sensitive unit was defective, the phone was repaired under warranty. My issue now is getting my apps & settings back. I have meanwhile read elsewhere that Nandroid doesn't back up the apps - pretty deceptive "backs up everything!" "it is like time travel" etc comments around here then.
Anyway, I reinstalled all the apps I had previously, and thought by reapplying the data partition from the nandroid backup it might then bring back the settings for the reinstalled apps. Instead all it did was remove all those apps again - now I am really confused. How come the restore DOESN'T bring back the apps I used to have, but DOES remove the ones I subsequently install. Does Nandroid touch the apps or doesn't it?
Touch screen not working
So i am having a very peculiar problem related to the GT-I9100 Touch Screen.
I bought the phone from Saudi Arabia and I live in Bangladesh at the moment. So for now I don't have warranty.
I bought it on 4th of this month. It had 2.3.3. So I updated it to 2.3.5. I did not use the phone much before that so I don't know if this problem was there before.
So here is the problem.
First time I noticed it when i pulled the phone from my pocket and could not unlock the pattern. First I thought I forgot the pattern. After sometime I noticed that i could not touch the buttons. I was dragging my finger over the points but there was no connecting line. I restarted the set. But it still did not work. After sometime I took the battery out. And after that it started normally and unlocked. And the touchscreen is totally fine.
I tested it using *#0*#. And every single point in the screen registers touch.
After that this happened couple of times. First couple of days I thought it was a pattern unlock problem. But i tried PIN and Password even using no unlock. It happened in every case.
So after couple of days it totally stopped happening.
But from yesterday it is happening again. And today it happened 3 times.
So today as I had no unlock protocol i tried tapping Home twice. As this brings on the voice command menu. And for the first time i was in the phone without touching the screen.And first i noticed the Menu and Back Soft keys works.And the touchscreen still does not work. And i noticed some thing weird. Always some thing in the screen is Selected. In Menu the + Icon is selected. In first screen the Map icon is selected. Also in Recent Apps the first App is selected. So after a lot of reboots it is back to normal again. Now i see something interesting. In the Battery Usage Graph i can see some really sharp drops. 3 times. Looks like when this happens phones charge takes a nose dive.
So here is the Gist.
Info related the Problem:
1. Usually happens when the phone is my pant pocket for sometime. It does not happen if it is sitting on the table.
2. Touchscreen gets totally disabled.
3. I have no idea why this happens.The exact reason behind it.
4. Battery Charge takes a nose dive when this happens. See the attached images.
5. I still don't know how to bring it back. Sometimes a simple reboot works. Sometimes I have to pull the battery. And sometimes it works on its own.
6. Every other function of the phone works. Like music playback using my UE 200vi music keys using PowerAMP, Siri(Android version), Call can be received using headset.
Battery nose Dive:

Also the selection
dl.dropbox.com/u/30943431/SC20111116-202146.png
So this is the thing. My biggest problem right now is, I don't know why it happens and I don't know how to bring it back from this situation. If I knew I could make sure I don't get it again or I would just fix it every-time. As when this happens I cant make calls or anything which requires the touchscreen.
So guys help me if you can by giving ideas. As i will not go back to KSA in 6 months. So buying a $550 phone unlocked was a total waste. As i cant use it here.
Thanks a million in advance.

Having the same problem while charging touch screen doesn't work

I will write more observations

Camera isn't working CM11

Hello,
My camera suddenly stopped working :[
I have cm11, and when I try to launch the app, it says "can't connect to the camera".
I tried rebooting, tried to factory restore, tried different apps, still nothing :|
Is there way to check that the camera is connected? maybe for some reason it disconnected
from the motherboard?
Flash stock firmware and factory reset, if still the same then reconnect/replace the camera module. I replaced mine recently, it took me 10 minutes and cost £5.
So after everything else didn't work,
decided to take apart the phone.
Turned out that the camera was disconnected as I thought,
Have no Idea how that happened, the phone did fall few days ago,
not that hard though...
Anyway works now, just the resolution settings for the back cam are the same
as for the front one... max resolution is 1.9mp :\
Will try to flash again...

Phone shuts down when taking a picture with flash enable [weird problem]

Hello All!
I'm quite new to this forum and not sure if anyone else had this problem before, but I think it's worth a thread anyway. I always solved my android problems on my own, though I haven't got the slightest of clues of what's going on with my phone right now.
So the problem is what's the title of the thread. Whenever I take a picture with the camera with flash enabled, the phone shuts down or freezes. Not sure which, because the screen goes black immediately after taking the picture, and it will not come back by touching the screen or pushing the power button or pushing it for a long time to switch it on or restart it. The phone only comes back to life if I remove the battery and put it back.
Some testing I did so far:
- The flash is working on it's own, it doesn't cause any problem. I tried it with a flashlight app.
- the camera works well without flash enabled, no shut down/freeze there.
- tried 2 camera apps, Camera Zoom FX, and the stock camera app for Samsung S3. Both caused the shut down / freeze thing with flash enabled when I took the picture, and both worked well without flash enabled.
- The only modification I did recently is replacing the battery, which works pretty well without any issues or strange behaviour.
Some other info's that might be needed:
Model : GT-I9300
The phone is rooted.
Android version : 4.3 - Stock (no modification, not flashed, no cyanogenmod)
Any suggestions?
Hello and welcome on XDA,
I would like to know which battery you are using.
After that I would suggest you doing a factory reset.
Kind regards

Camera drivers have probably borked.. It has happened to my old s3 a while ago.
Backup, reset, flash stock twice and go from there. It's the only real fix that i know of.

Front Camera Disappeared?

Today I noticed that my phone wasn't recognizing my face ( I usually use Smart Lock trusted face) and I opened the camera app to see what's up. What I found was that the button to change to the front cam was completely gone. I then tried snapchat, which also couldn't open the front cam. I even tried going through the service menu -> service tests -> front camera but once again, nothing happened. No amount of reboots seems to help, so yeah... any suggestions?
possibly a hardware issue/malfunction > try a factory reset after a backup to rule out software problems.
Your phone must be physically broken. Is its charge port looser or tighter than before?

Back, Front camera and Flash stopped after apps transfer to sd card

Hi,
Something strange happened with my z5c E5823 running stock 7.1.1. Here is the riddle
I got a message the other day, saying space on internal memory is decreasing and the option to transfer stuff to SD card. Since there were almost no pictures and music on the phone, I keep them on SD card, there was the option to transfer about 2GB of Apps. I choose that (big mistake when I think of it now) .
I continued using the phone while the transfer was in progress and @ some point , the phone crashed. That never happened before. Screen froze and stayed like that for around 10 min, completely inactive, and the phone restarted itself alone. After this it all seemed fine until I tried to start the Camera app. It just gave me black screen and some seconds later the message - Camera has stopped/ Restart app.
The front camera and flashlight don't work either.
Another weather app - AcuWeather didn't want to start too, but after reinstalling it it was alright.
There is no such option for the camera app and clearing data and restarting didn't help.
Decided I will do a Factory reset for the first time since I use the device and tried a manual back up of all the info to the SD card. Contacts , personal info and settings backed up successfully , but the process hanged up at 50% when transferring apps. It crashed and stooped. Tried it 2 times !
Since back up wasn't possible I proceeded with the factory reset and after that the phone successfully restored my personal data, without the apps , but the camera didn't work. I did a Software repair with xperia companion with the same result.
Another bug appeared. When I pull down the full notification bar, and want to edit/rearrange the icons/shortcuts and press the little pencil next to the settings(gear) icon, the phone freezes for a few seconds and than the screen turns black. The phone is unusable at that point, thought it works, and receives calls which i can not answer. I only can restart it, because the power button gets me to the window for power off and restart.
Than I read some camera sensors might get disconnected from the board so I opened the phone , but it was alright inside. nothing changed.
Now I got an open phone and no answer or clue whatsoever of how to proceed.
Any ideas are very welcome!
I there a way to reset the phone to an earlier version of android?
Thanks inadvance!
