    hi
    have multiple times a day black screen and need to pull the batery to get it going again
    also sometimes the screen goes all funny

    now i noticed sometimes it gets really hot on front and behind just under where the camera is
    for example i factory reset and its getting really hot then

    could this be the mainboard failing? and is it worth trying to replace the mainboard?

    When this happens, see if you can check your battery stats after a battery pull to see if any particular app was using excessive battery.

    If you have an SD card, try Unmounting it (in Settings>Storage), in case the card or a file on it is corrupt. This can case overheating and other various issues.

    Also try wiping the cache partition: https://support.t-mobile.com/docs/DOC-11017

    It may very well be a motherboard failure. The only other thing I can think of trying is reinstalling the firmware, either using Kies, Smart Switch, or Odin:

    I'm afraid I don't know anything about switching out motherboards, sorry!
