When i'm charging my phone I try to unlock it with the pattern and as soon as i start to slide it just says incorrect pattern it is like the screen doesn't recognize my fingers and wont follow my finger as i try to input my pattern. I know this isn't a hardware error as i purchased this phone 5 days ago and my brother got the same phone. We both have this problem. If any of you got any solutions let me know. It only happens when i'm charging my phone.
