Never really had any problems, besides the occasional freezing, until a few days ago. It was on the charger and worked fine before I went to sleep, but when I woke up, it was shut off and would only turn on every once in a while. When it did, it shut off after a bit. It started working fine for a day or two, but repeated this problem, and started working again. Now it won't turn on at all. The battery worked on someone else's KIN, so it shouldn't be that. I tried taking out the battery for a bit and I've kept in on the charger to no avail. It has been three days since it shut off and still isn't turning on. Any ideas on how to fix this problem would be appreciated, for I don't want to lose my pictures and whatnot. Thank you.
