Hi i'm in university and have been revising my finals for the past 3 weeks at home. (meaning my phone has been perfectly safe within my room for the past 3 weeks, no water, no drops, nothing dangerous). I charged my phone, used it yesterday morning, took my exam, and as soon as it finished, my phone suddenly wouldn't turn on AT ALL (it had only been 2 hours!). i have tried every single method listed online (holding down volume + power button, charging, safe mode, connecting via itunes, holding down power button, etc), and nothing works! what do you think is wrong with it? i have a lot of important information on my phone, will i lose all my data? how the hell does an iphone randomly stop working out of nowhere??
