Sounds like a hardware problem if flashing stock and factory resetting doesn't solve it.
My power button had a problem that causes the phone to reboot infinitelly sometimes, it gets stuck inside even if I can still press it.
Well, pressing it a couple times normally works for me. But to be sure I stopped using it, double tap status bar to screen off and home button to screen on.
It's really bad when it stucks...
No its not a sort of that problem coz I already checked that, but now I think I am able to get this problem solved but now no sim card is working its keeps displaying Emergency calls only..

Go to about phone, status and check they match what is on the box or under the battery on the sticker.
Yes just checked its same. Now the set is again restarting but the time increased even if I switched off the phone it will turned on itself, is it like a hardware problem? I tried different versions of firmwares. Also few days back mother boards EMMC chip get repaired , is this belongs to that issue?
It can be a hardware problem
One more thing I noticed. I switched off the phone after few time it automatically switched on
Your power button is faulty.
hi, i have the same pb? i checked the power button is ok, i try a lot of rom (official & custom) no solution?
Nand memory is damaged, go read the the emmc freezing thread.
Is this hardware issue?

It doesn't sound that great to me. If a reflash didn't work, why don't you try an different rom. Just to rule out a rom error.

Hello,
I bought recently the new SGS3 and after a week or two of using I noticed the phone loses all the sounds despite all of them are turned on and not being on minimum. After a while the sounds get back and everything works fine. At first I thought it might be from the settings because I set up silent mode for all notifications and I thought it may turn all the sounds off, despite it normally shouldn't. After playing for a while with the phone I realized the issue appears randomly without any reasons while I was playing game or simply navigating through the phone. If anyone had experienced the same issue or have an idea what could be the problem (software, hardware, settings, OS, etc) or how it can be solved, please respond. Any answer is appreciated as the problem is quite annoying as I'm missing calls because of it.
Thank you.
Phone details:
Samsung Galaxy S III
Android version - 4.0.4
Baseband version - I9300BOLF1
Kernel version - 3.0.15-782020
Build number - IMM76D.I9300XXBLFB
P.S. Restart of the phone doesn't help as I already tried it. The issues is related to all the sounds not to the vibration, the last works fine.
Backup data and factory reset.

Thank you for your advise JJEgan, unfortunately it didn't help neither. Yesterday I did the factory reset and left it as it is, didn't restore any of my previous settings or apps, didn't install anything additional, just wanted to see if the problem will appear again, and unfortunately it did.
Anything else I can try or I should take it to a service?
Thank you
I have the same problem with notification sounds. The problem appears when i turn off notifications on apk like im+ or Yahoo messenger. Is there any other solution rather than factory rest?

maybe there is some loose..should send back to samsung
It happened to last night. I restored the phone using CWM and now is back to normal.
I have a samsung Galaxy S3 GT-19300.I got it from Italy.I Used It for sometime and then the update 4.1.2 came out.So I Installed It.Then Minor Wifi Problems Came.I somehow Fixed It,using Methods I Found From The Internet.Then I Didnt Use Wifi For Sometime As My ROuter Was Broken,And When I Got A New One ,I Tryed connecting To WIFI ,But It wouldnt turn on.
In The Notification Panel when I Press the wifi button ,it turns light green and then becomes normal again.In settings when I Go to Wifi and turn it on,it keeps on saying turning on for sometime and becomes Off again.
I almost Tried Every Solution On The Web.I Tried Dialling *0011* and turning power save off.I Flashed New Firmware around 4 times.(now im currently running 4.3,got it from Cnet)And In All Of Them ,Wifi Doesnt Turn On.Then I Went To Desperate Measures I Rooted My Phone,and tried many Fixes But It Still Didnt Work.
Right now im thinking,something must be wrong with the phone`s wifi adapter.(Physically)AND HOW I WISH THAT IS WRONG.
So i Really REALLY APRECIATE It If U can Help Me.Now That my warranty is void as well,U People are My Only hope.Im Running Very Low On Money so im hoping For A Free Fix.I still even have the Idea Of reverting it Back To 4.1.1.But that Would Make My Phone Lose A Lot Of Features,i Dont Like That.But Anyway If Thats My Only Choice Ill Take It.
Also I Live In Sri Lanka,I Tried Another Reigon update and then My Mobile carrier Didnt work,also wifi didnt work as well.
This Is My First Post Any Help would be appreciated.
Thank You.
P.S - I Would Rather Prefer A Fix In 4.3 or 4.2.2 Other Than The Link To 4.1.1.

Hi All,
I have A116, which behaving bit weird. 6 months back, while on charging, it started operating on its own, when I removed it from charging, it stopped. While on charging with that particular charger, issue was there. I changed the charger, everything was OK. Recently, on a ugly morning, I answered a call at 5 am and around 6 am I tried to make a call and found that screen is absolutely irresponsive. Sometime later it unlocked on its own, started operating on its own, like opening any random app or web or anything and does some random operation. Tried to power reset the phone half a dozen time no go, removed both SIM and memory card. still the same. This has completely wiped out my phone data (phone book, all SMS, photo, mp3's video's), factory reset in other words (on its own). I was told its battery issue, changed that too. no go. . This is happening not always, it happens for a while and then behaves normal and after 5 minutes old story repeats.
The best part it had wiped out avast anti-virus too....
Any one heard of this..? Any solution without going to service center..?
thanks,
Narendra

Thats a big problem i think you have installed some malicious app with root permission or this is the problem with your TP. I think there might have been a problem while your TP would have been updated.
Solution:-
1. Go to micromax service center and tell them ur problem.
2. Try to flash stock rom again with sp flash tools.
3. If you are already on 4.1 than update to 4.2 else do vice versa.
Important:-TP means Touch Panel
My solution will definately help you :good:

the problem you are reporting is common in most canvas phones with older firmware. update the firmware

it's easy. check this out.
http://forum.xda-developers.com/showthread.php?t=2292971
use factory reset to flash the new firmware. (you can root and install recovery if you want)
I faced a similar problem some time back.
I visited the service center in Azadpur(or nearby Azadpur Metro station, do not remember the exact address) and they fixed it in 30 minutes of wait time. Try visiting their service center..I had stock ROM back then though..!!
High Voltage
when u get high voltage in your supply....

no need to flash again......

you got the same old stock firmware alright. but it's the newer one. Micromax has updated their stock rom many times since android 4.1
v1 - Android 4.1.2 Initial version. Lots of bugs. You could install Flipboard app and see the entire device bricked.
v2 - Android 4.1.2 Update. Flipboard bug fixed. Yet there was another issue, which caused the touch pad to malfunction while charging. other bugs include the app storage issue. you can't install apps in external sd card and storage space was very small.
v3 - Android 4.2.1. TouchPad issue was fixed. Apps can be installed on external sd card. OTA firmware update support was added but it doesn't work.
v4 - Android 4.2.1 Update - New Camera App. OTA issue was never fixed.
v5 - the newest firmware from micromax which was launched with Micromax A116i. No bugs so far.
Micromax service center must have updated your firmware to Android 4.2.1. version 3
Ur problem was because of charging...
Voltage problem not a software problem...
Use ur own charger without any extension or any external supply...
U will not face any issue like this...

Hi guys,
This is my first post.
I just got a Sony Z2, and yesterday I updated it to latest firmware 17.1.1.A.0.402 using flashtool. After that, everytime when I switch off my phone and turn it on, the message of "...android.process.acore has stopped" appeared.
I tried to flashed the phone again using PC Companion to re-update the same firmware. I though the error message has gone but than it is still there.
I have tried several ways as mentioned in this forum but the problem seem to be there. I don't see any problem/error caused by this error message yet.
Any idea/solution to completely remove the message?
Go into settings > apps > all apps, clear all data for anything relating to contacts then all will be fine, make sure contacts are backed up tho of course

I also have the same issue as the OP. It particularly happened after I upgraded to .402 using PC companion.The message will appear always after restarting. My devices has not been rooted. Tried to clear data and cache for contact apps, but after restarting, the message appeared again. I am still lazy to do a re-install because aside from the message appearing only after a restart, there are no other major effect to my Z2's performance. but clearing it will be nice though.
I have the same thing when i touch the phone immediatly when it just restarted, but when i restart and leave it untill screen goes off i don't get the message.

Hi guys,
Thank you for your info.
I tried to disable contact sync of Viber and I think the message has temporarily gone. Sometimes it still pop up but not as often as before I disabled the contact sync of Viber.
Apparently, this problem is caused by contact synchronisation between Viber, Facebook, Messenger, Whatsapp, etc. Other users, such as Samsung phone users, reported that they have the same issue but when they turned off contact sync of the above-mentioned apps, the error message somehow has gone.
To be honest, I have just recently switched to android from iPhone, and I have been usings iOS for years and never seen any kind of issue/error like this on iOS. However, Sony Z2 is one of the greatest phone I ever owned and I am so happy with it, specially its crazy battery life.
Hope you guys will share your solution here if someone can fix it permanently.
Cheers,

i had this problem, amongst others stopping my phone. i pulled the sim card out, then rebooted the phone. the phone then showed it was updating all apps i let it boot up and it seemed to work. pulled battery and put sim card back in. and all ok so far. i have sent my phone 3 times away to vodafone for this repair, with android.clock stopping, android.phone stopped working and the phone actually crashing on the samsung screen and not even booting up. each time all they do is a factory reset. like duhhhh, i have never thought of that (sarcasm). i am hoping that doing this, will give my phone some sort of permanency in it's repair. i have not rooted the phone, it is stock.
Vodofone refused to replace the handset even though it had been in so many times for repair. word of advice. steer clear of vodafone. i am cancelling all my contracts with them.
sorry that went off topic, but i want a phone that works and vodafone will not help you in that matter.

Xperia's have unremovable batteries, maybe you should steer clear of Samsungs
Is that a good thing or a bad thing though? Cos sometimes taking a battery out is what could be needed to fix a problem.
But point taken. Perhaps a change of manufacturer would help

I know people who advocated pulling the battery from devices as the only answer but I've yet to come across a situation on any device which couldn't be handled with >adb reboot or a three finger reset.
There's actually a method on Xperia devices, to disconnect the battery and plug it back. It's called "Hard Reset". Yeah you don't take the battery out in reality, but this method does it in Matrix dimension. So, the consequences are the same.
