Hi, this video shows 3 faults that I believe will become very common as the Nintendo Switch ages.
The first fault is a loose kickstand which is easy to fix.
The second fault is a joycon which could be not syncing/charging or the fault shown in the video is not making the connection click, these faults are easy to fix.
The third fault is a Joy-Con which keeps unlatching from the Switch, this fault cannot be easily fixed but I give a couple of preventative ideas to stop it from happening.
Many thanks Vince
