mine started "sticking" a few months ago. maybe september, i'm not sure, which is total garbage since i bought my lite brand new in march. holding the left stick down didn't register fully and my character would stutter in her walking cycle, between slow and fast. re-calibrating the stick worked for a little while but stopped having an effect these past few weeks. now i have to blow into/under the stick before i play and that's been working so far.
this morning, my ac character finally moved on her own. stick was working fine for a good five minutes and then, out of nowhere, the character started slowly walking right on her own. blowing didn't work and i had to somewhat aggressively rotate the stick a couple of times before it stopped. fortunately it hasn't been an issue again so far today but i don't doubt it will resurface again which sucks.
since it's a lite, i can't just send in the controller and i don't really want to send in my device for repair (if i even can for free) because turnover time is said to be like 2-3 weeks, during which i obviously wouldn't be able to play, and i don't want to go third party in case they accidentally break my device or wipe my data. (which is also why i don't want to send it to nintendo themselves tbh.) £200 for a console they know is defective and barely lasted half a year is such trash.
