I have some problems with my touchpad. Firstly, when i want to put some files on int, i drag and drop these files on device correctly probably, but after ejection touchpad doesn't see them. This includes pdfs and mp4 movies.
Next, facebook app. I opened it one after first activation and after that it doesn't work.
Someone help?

PS, sorry for grammar mistakes. English isn't my native language. I hope I descipted everything clearly.
