May I ask what phone you are using? I've only seen such issues myself with very cheap phones.
I've tried Samsung top of the line phones, Iphones, Ipads, Sony flagship phones (my family loves their over expensive phones).
I hae a Xiaomi phone, excellent phone and normally hasn't any problems with finger detection.
I think that my skin is so thick that it somehow prevents the screen from detecting my fingers. Nose works everytime.
EDIT. About Ninty taking the Switch back, there is clearly a lot other things going on there so I wouldn't blame Nintendo solely for this... I love it how Gaf always jumps straight for throat if there's is a chance to bash Nintendo. The guy himself said that there is other things to consider. Ofc it looks bad for Nintendo if someone holds the information about everything else and just says that Nintendo took his toy away and didn't give any money back...
