I have same problems and I can't figure out why does this the cellphone. I checked the file explorer on my PC and a didn't find anything, I tried to delete the temp files and it didn't work. Once it worked, but another time not. I would like to update asphalt and I can't because media files fill the remaining free. I got a suggestion, reset your phone, but It is not the best solution. Acconts set up again, app downloding etc.
