I noticed that after updating my samsung tab 4, my external bluetooth keyboard start malforming and the keys are not aligned and after reading updates on people's having similar challenges I thought of reverting to the old software but it was not possible.
Please how can I make my external keyboard functional with this latest update.
Software version: T835XXU3BSF4/T835OXM3BSF4/T835XXUBSF4

Just to confirm, no change in the behavior of the keyboard if you load the tablet into safe mode?
If the factory reset Jamess467 suggested doesn't help, repairs would be my next recommendation.
