I bought a leader international 7" Android tablet versiion 2.2 and since i got it it was able to download programs then all of a sudden something happens and leader tells me to restore it to factory settings. Then after i hang up my memory is messed up and whenever i try to download an app or a picture from facebook it says download unsucessful or there is not enough free space available when the memory is full and there is like none used. Also even if i ignore that and put either a 2 gb or 16 gb flash drive it installs it then says its ready for removal. Same when i enter a micro-sd card it has the same problem. What in the world do i do? thanks in advance.
