Hi, I don’t think the Nothing Phone (2) is outdated and don’t really know why people are getting this idea. In terms of performance, it still is the best phone Nothing has to offer, it also is the only one which has an optional 512 gigs of memory. It also features wireless charging, something the other models are lacking.
In terms of updates, it just got Android 15 with Nothing OS 3.0 a week before christmas, so that major update isn’t even three months old by now and it got another small update back in January. Nothing only does bimonthly security updates with all their phones and isn’t on a fixed schedule, so the next update should arrive sometime this month. That’s the case with all of their phones. The only time they are (much) more frequent with updates is for new phones, which usually get multiple updates within the first few months.
Of course it is lacking a telephoto camera, but that was known right from the start. It’s also lacking eSIM support, something which the 3a Pro introduces as the first Nothing Phone with this feature and I’m pretty sure the Phone (3) will also have eSIM.
