Friend accidentally fell asleep while charging her phone and this screen appeared when my friend woke up
My friend was charging her phone late at night and accidentally fell asleep. When she woke up, the following image popped up on her phone's screen (pictured below). She tried emptying and refilling the battery to no avail. How do we fix it without restoring/removing the files within her phone? If it's unfixable, is it possible to save the files/data/pictures/apps from her phone to another device? If so, how?
Bits of Info:
- Battery tended to drain very fast recently
- From 100% to 50% in one hour when used
- Started approx. last week
- The screen shattered before from a fall (but replaced with a new lcd)
