so ive been a touch pro user since may 09 and i love the phone i think its freakin sweet. however ive had to replace it 3 times already due to the keyboard. now after getting my latest replacement less than a month ago and FINALLY finding a rom i love (calkulins) and getting all the apps and a sweet panoramic bkgrnd my phones started tweakin out in a new way. my phone rapidly blinks back and forth between landscape and portrait mode, has long and annoying screen black outs when exiting texts and my battery life has gone waaay downhill. i can make due with the last one, the messaging one im working on but im clueless as to the first issue. what should i do? id hate to have to buy a different phone cause i love the tf3d and the pro but i cant keep getting replacements every other month
