has anyone been having problems with the pattern lock? sometimes when i go to do my pattern its really really sensitive and will give me the red mistake circle when I'm doing the right pattern. i then do it supper slow with perfect lines and it won't work. it took me almost 2 min to unlock my phone before, its just to sensitive and faulty. i turn the screen off and back on it just won't work and then suddenly it will work again and be easier to unlock.. very mysterious. am i the only one getting this problem? is my phone being worked to hard...could it be getting slow already!? i really don't think i have much going on on the phone.
