Hi! I wanted to see if someone has the same problem and if someone can help me out! I bought samsung galaxy ace plus last month and pattern lock was working totally ok, but a few days ago, when I tried to unlock my phone it looked like I'm not touching dots (there is no white line that connects them and they don't get green when I touch them). Till now, the problem is still there. If you draw a right pattern the phone will unlock, and if you don't, dots turn red as they should. This isn't a big problem because I'am able to unlock it, but I was wondering why is it like that and I was thinking if it can be a virus that is effecting that.
