Since i updated my S7500 from JB to CM 10.2,
my phone is not turning on by the power button, all what is happened when i press it, is that the screen goes on for 2 or 3 sec. with a vibration, then it goes off again.
i have to go to recovery mode and choose " reboot system now "
and this is the only way to turn on my phone
i updated the OS from CM 10.2 to CM11 SpeedMode_KK 2.2 to CM11_SM_kk 2.2.1, but the same problem
i use CWM 220.127.116.11
