Tomtom Go professional 620/520 screen go crazy after firmware update

hi, i bought a used Tomtom Go proffesional 620 and after i did a update of speadcameras and firmware update (is a must) screen started to be crazy, it switch (tap) icons by it self etc. when typing a word "leicester" i am getting leiccelostter" or so, the strange is that it putting the letters that my finger is not even close to, its hard to swipe coz the screen most likely do a tap instead of swipe.

I decided to give a sat nav back as i was not sure it was like that before update coz i use it only few minutes before i procced to do an update.

i bought another unit, new one but go 520 professional and all the same happend, WHY ??? idid all updates now and still can't write the word i want.

    Hi
    @adamvfr

    Be VERY careful with some the the latest USB Charges
    Always check the OUTPUT specs of the Power adapter
    The Power adapter for a friends Microsoft Windows Tablet uses High-speed USB charging 19Volts yes Nineteen volts... Not the usual 5Volts
