Katy vor 6 Monaten 0

I was animating on my phone then all of a sudden my screen whent black and then it showed me that my phone reseted so I said”ok this ok this is kinda normal”. So when it was done resetting I when to FlipaClip to continue my animation,but everything was gone,except for the ones I saved on my device,I don’t know what to do,my friend had this happened to her but she’s doesn’t know how it got  fixed and she has a new tablet that doesn’t do that. What do I do?
