Bad Problems	Samsung Galaxy S II (GT-I9100) problems review by end-users Users commented on the charging issues. When the phone is completely dead out of battery. By charging it to restore battery won't work. Some others charging the phone and showing the charging icon bleeping but actually the battery never charge at all after many hours. The screen brightness adjustment is not giving significant contrast. When user set the brightness to the lowest minimum the screen still as brightest as ever. The Samsung Galaxy S II auto-shut down issue is quite serious as some users are complaining about it. Wi-Fi issue - some users commented on poor Wi-Fi connection speed.
