ok well could be a few things, but i reckon your processor is having issues we had a samsung with a similar issue a few years back TV repair man said that firmware had corrupted itself, however we never got it fixed as new years eve we got burgled and some nicked it!
trouble is spesh have lowered the camber top tube height to mirror a 26″ wheeled bike & done some geometry tweeks again to make it feel like a 26″ bike…..whats the point.
