[freemizuivy]

so i just got my iPhone 6s yesterday and i swear it hasn't completed 24 hours and it randomly shuts down/ restarts itself for more than 8 TIMES now especially when i open safari, whatsapp, instagram etc .. it shows this ugly looking grey scratched screen for a second and restarts itself or just shuts down and i have to hold the power button so it would work again.. i just got it and i was super happy but now I'm frustrated and just disappointed

iPhone 6s ,64GB ,running IOS 9.0.2
HELP plz!

Try restarting the phone yourself. If that doesn't help, try resetting all settings. If that doesn't do it try restoring the phone as new. And if that doesn't work or if you don't want to try some of those things then you might need to contact Apple to see what they might have to say about it.
