Hi, since a couple of weeks I have some problems with the playback of my movies and TV shows using my Lenovo Tab 4. Every couple of minutes the playback is jumping around 30 seconds ahead and then behaves weird while trying to go back. (It only goes back 2 instead of 10 seconds) Last time I tried it happened seven times in 4 minutes. I don’t have any problems using my pc, mac or iPad. Right now I’m out of any ideas what I can do and I’m glad if someone could help.
