This 6 month multimeter have strange behavior. It change to current measurement mode itself. When teardown the meter i didnt see any damage. After covering trace below current mode button with a isolation tape(black tape) i havent encounter this problem again.

UT60S has detection of correct probe connection. Perhaps the two separated halves of the uA connector are shorting each other. When they close, they command the multimeter to turn on the current measurement mode.
The contact plates themselves can short out, or something metal could get in there.
