I recently lost my samsung guru on my way to office and then I had to switch back the old galaxy i7500 lying around for months. It was still alive and had recently been services(the touchscreen) by the authorized service centre.
I am comfortable with recovery/rom and before sending it to service I had galaxo 1.6(the latest stable back then) on my phone. I even had some(3 to be exact) nandroid backups on my phone. After it returned from the service centre it started acting strange. Now the problem begins.
It looks & works completely fine until I call somebody. Then something just starts running in the background, random keypresses, some random application starts, and I see the volume bar all the time as some continuous volume up command is given, I presume. It just goes on like this during the entire call and even a few seconds after the call. Another problem is it silents my phone every time someone calls me, so no matter what I set in the settings I never ever hear a ring when someone calls me, even the vibration gets off.
Solutions I tried: Obviously I tried formatting the storage(it doesn't have any external storage). Flashing the ROM, changing the ROM, drakaz 2.1, recovery 6.6 etc. Nothing helped, I even tried(with some workaround) and got the old nandroid backup restored . .. but to no avail. I have currently Kaspersky installed on my phone but even it can not detect anything. I have not given odin a try yet as I am on Mac and currently not very comfortable with heimdall.
I must thank you for reading this long post of mine & appreciate any little help any of you can offer, even some sympathy will do.
Thanks in advance,
