My Samsung Galaxy J2 is hanging very badly.it is not working properly the battery level reduces automatically, without using the phone.its takes too much time while game loading.whenever I play game the game software goes crashed.The sound quality is cheap and low quality.its touch does not works properly with thumb.The design is not so good but fine.the mobile looks likes old age phone.at the same price I can purchase good mobile but I was don’t know about it and wasted money by buying Samsung Galaxy J2
