LG Lotus

Coming from an ic902 phone I really appreciate the qwerty keyboard. I like the phone, but two things; second day I had it a line showed up across my screen that won't go away, and sometimes the phone never receives the call when people call me. I tested it myself and got mixed results. Did anyone else encounter these things? Maybe it's an isolated incident. I plan to replace it this weekend. This phone is really nice other than that.
