[Galaxy S III General] juddaeng:
Ok, let me post experiences that I had.

What happened:

Symptom 1: suddent death of the phone and stuck at booting after rebooting. (I had to reflash the Rom to make it work)

Symptom 2: delays in response. (I have to push at least two times for it to respond)

Symptom 3: dimming of front camera.

Symptom 4: 'No service' error message on status bar

What ROM/Firmware: Stock JB roms (Poland, France, UK, Indian)

What kernel: Stock

OC or UV: No

Where phone was made: I bought it in South Africa (Vodacom)

Where battery was made: Made in Korea and assembled in Vietnam

It is a very long story :silly:

Ok, the problem started after I flashing different stock JB roms that were released.

I have three official SGS3 batteries, one that came with my phone, the other one came with my wife's phone and the last one from South Korea that I bought from Samsung.

I bought my phone in August, I think :confused: and I bought my wife's phone in October.

My wife was using the battery from South Korea and I was using my original battery that came with my phone.

One day, my battery was flat so I used the battery that came with my wife's phone.

Somehow I felt the phone became bit slow. A little while later I found out that my phone was completely 'dead'.

I tried to reboot but the phone was frozen at the boot logo. I removed battery and put it back on and reboot again, still stuck at the boot logo.

I factory reseted the phone by recovery mode, still stuck at the boot logo.

I reflashed with the same rom (I think I was using French JB rom at that time) still stuck at the boot logo.

Then I flashed the phone with different JB rom (Polish) then it was actually booting properly.

I was quite freaked out at the time :eek: This happened to me few times when I was using the battery that came with my wife's phone.

So I after few flashing I decided not to use that battery.

Then few days earlier, my front camera was acting weird. It was very dim, rather very dark. I compared it with my wife's phone and it was definitely darker than my wife's phone. I freaked out again. I tried rebooting, factory reset, camera reset.... nothing fixed the dark fron camera.

So I reflashed the phone (I was using latest UK JB rom), it was working properly after the reflash.

But the camera became very dark again... So I flashed the phone with different JB roms and still the same story... Worked fine at the beginning but it became dark later.

So I decided to take it to the repair centre (Vodacom repair shop) and told them my camera was acting weird. (I downgraded the phone to stock ICS before I took it in for repair and the front camera was working normal:eek::eek:)

Next day they told me that the phone is ready for collection. They told me that it was software problem and they have upgraded the Firmware (it was still ICS though....)

I switched on the phone and everything was looking alright so I flashed the phone with Indian JB rom to test if the camera problem was gone.

But........ the problem was still there.... so I thought I will just give up and just use it as it is and flashed back to ICS again...

Everything was fine again...

The third story begins now :laugh:

I was curious, what would that problem battery that I mentioned above would do to my phone.

So I replaced the battery and switched the phone on.

The phone was fine :cyclops:

But the only problem was.... the phone could not connect to the network and it gave me 'no service' error message on the status bar...:eek:

I replaced the battery to my original battery and there was signal....:eek:

How weird is that?:eek::eek::eek::eek::eek::eek:

So I took it back to the repair centre and showed them the problem and they also freaked out :cyclops:

Now it is in for repair and they will let me know as soon as the fault is found....

I will let you know as soon as hear from them...:fingers-crossed:

Thanks for reading my long boring story...:p
