Receiver changes channel by itself

[caboclipper]

Hello: I have a few Direct Stream receivers, they are the osprey android version. The problem I am having is that it changes its channel number by itself... nobody touching the remote or anything.... it happens with all of them at different times
any ideas?
best regards
