Crazy player
 

bought 3 2" mp4 players... 2 of them were alright, but another that i just received is doing some strange things... Usually i even can't turn it on, but then i succeed it just turns off again after few seconds... sometimes I manage to get to music section, but it turns off again... firmware is 9.0.48. Any suggestions?

Neoner , just before it turns off, is there any low battery indicator or does it show the "Bye Bye" screen?

no, battery was fully charged, and I found out problem... Contacts with battery were faulty, I repaired them and everything is fine now :)
