Sometimes when i unlock the phone by pressing the power button the screen doesn't respond when i want to unlock it...it's seems to be frozen and i have to lock the phone again and again and after that i can unlock the phone...this happens once a day sometimes...sometimes twice or more and sometimes don't happen...i have the 4.3 android jelly bean version...who encounter this bug ? what should i do?
hello just asking if i will try to repair my firmware using pc companion in this step (Accept data removal) will all my data and apps installed will be gone and lost?
