iphone7+
my iphone 7+ is facing many problems, my whatsapp history partially was deleted, i cannot take any pictures without them turning grey, i cannot take snapshots either. i proceeded to reset all settings but now i cant even log in to icloud, i also cannot open any apps without it crashing
most apps takes 5+ minutes to open. i have no idea what to do, ive tried to power off my phone/powering on again, it doesnt work
Also, it does not download ios11 so i cannot update my phone either wirelessly, its on ios10.2 right now
