Kugoo Kirin S4 repair, thumb throttle repair and change

I received a Kugoo e scooter for repair which did not respond at all to the accelerator. All the indications were to check the throttle and the cause of the fault was found.
Since I re-soldered the Hall sensor with the broken leg, it could not get into the magnetic field between the two magnets perfectly. So the test was successful but I ended up replacing the throttle with a new one.

Hi. Tap display error. What could be the problem?

Hi, I only had the scooter for a short time for repairs. On the motherboard, I would check whether there is a cracked solder, and I would check the connectors of the cable ribbons of the display (touch screen).
