I am thinking of buy Sonic & Shovel knight just wondering how it plays with the d-pad on the joycon? Also can anyone else recommend any other 2D games that work well in handheld mode.

I'm very addicted to Switch news and outside of that mentioned Reddit thread I have barely seen that Screen issue mentioned. I think some people got unlucky but wouldn't say it's a common issue like say the joy con problem.
Aside from that, contact Nintendo and get it sent off and sorted. Mine went from Nintendo PT to Nintendo in Spain and it was repaired and returned in exactly one week. Allowing for a couple of days postage either side and the weekend that's literally 1 or 2 days actual repair time from arrival.
They are both fine as diagonals are not needed.

Thanks i brought Sonic and its great fun works well on the pro controller and handheld, time to buy shove knight any other eshop titles you can recommend?
For single player those are the best. Slime San is brilliant if you like meat boy too.
.. never again...I best stay away from Slime San, I don't want to end up throwing my switch in rage moment.Super meat boy....... never again...I best stay away from Slime San, I don't want to end up throwing my switch in rage moment.
