Late last night, as my wife was using her z1 to surf the web and noticed her phone was low on battery, she went upstairs to plug it in. When she did that, her phone started acting really strange, not responding to her touch inputs and randomly selecting things she didn't press. Out of nowhere, we notice that there are two long cracks in the screen! We are still dumbfounded how she was using it perfectly fine 5 minutes earlier, plugs it in and two huge cracks come out of nowhere! What I am wondering now and i'm hoping someone can help me, is if we can't get the screen fixed (mostly if its just too much to fix), is there a way to factory reset it without being able to use the screen to go into settings? Will i be able to back up her phone from the computer? (mostly text messages, i know i can get pictures and most data off of it, but she wants to keep her texts). Any help would be extremely appreciated. Thank you guys!
