so with my 8530 ill be texting my friend and then ill go to type my message and when i enter it sometimes it doesnt show up, and then sometimes if i try to scroll up to see the earlier messages and then try to scroll back down, it wont let me scroll all the way back down, so then i click back and then try to go into that chat with the person and it wont even let me in, and if it does it takes forever. tried a battery pull, but it didnt help.
