I bought on the market the Android7AVIPlayer. I copy on the phone the movies i want to watch, in avi format, the program see the movie but doesn't start them. The weight of these files are about 750 mb each one and on the sd card there is a lot of free space. There is also a lot of free spece on the main memory of the phone. Is there someone that has the same problem? Is there a freeware to convert the files to a different format so to have an easylier access to them??
