Hi, I would like to understand better some strange behaviour that began with M3S.

The bad symptoms are:

a) in the morning 3 or 4 long vibration tones of unknown origin

b) the Home button works sometimes during the day, but sometimes not,
I have to use Smart Touch to compensate.

c) 3 or 4 times a day, the phone turns off from standby state.
I must long press to turn it on again....like Soft Reset (very bad).

I scanned the phone with some antiviruses, but they found nothing noticeable.
The symptoms could be hardware related, but they are so different one from other.

Someone could help me to understand more? Thanks.
