iphone 6 jammed and blue screen
hi guys out there, i have a problem here. i just got my 64gb iphone6 back from warranty.
im using ios8.3 and i did a restore to this phone. i have been testing it for 5 days.
day1- after using phone suddenly jammed and stuck at apple logo. ( i did a restore again)
day2- phone suddenly off itself, i did home + power button reset to on it back.
day3- phone auto off itself so i thought something wrong with my backup, so i installed fresh ios without restoring.
day4- problem still same. suddenly off when it was on standby.
day5- everything seems ok until i was using safari app. it just "blue screen" and just restarted.
Since i was using a fresh install, do u guys think its a hardware problem or ios?
thinking to downgrade to 8.2 to see if problem still exist.
