Whenever im using the eris it seems to be messing up 80% percent of the it freezes up completely on me, it scrolls by itself, and when im texting it loves to just stop working...I use this eris as my work phone i have to text my boss alot and with my phone screwing up sometimes it takes me 10 min. just to send a text..also i performed a factory reset and my phones still doing the same exact thing..what should i do???
