My samsung katalyst screen is reversed. it's fine

I'm told this can happen if your memory is too full or the cable between the computer and the screen is dying. I don't know how to fix it. You might have to take it to a cell phone repair place or T-mobile if you still have your warranty. My Katalyst had the same problem for a couple weeks. Today the screen went completely white and restarting it hasn't fixed the problem. Hopefully I'll be able to hold out another 3 months until I can get a deal on a new phone.

IM not seeing an answer here but am having the same problem,

any suggestions anyone
