That's not too significant yet but I'm expecting the amounts to increase
The camera is of course the biggest drawback but apart from that, everything is fine.
The Galaxy S5 was one of the most popular phones and I especially bought it some years ago, because LineageOS support was supposed to be good. And it did run kind of ok, but certainly not "as snappy as a modern device just bought from the store".
And no, it does run as snappy as a modern device with the latest Android flashed to it, I can make a video if you don't believe me. Ironically it's even faster now in Android 13 than it ever was during its prime era.
You definitely would have much less luck with a random huawei.
You can have a look here on how it looks like for me, I do consider it snappy
How does browsing works?
Apps are opening quickly, animations are fast, typing doesn't lag, yeah I do consider that snappy.
Sure if you start a game, it will just destroy the poor gpu and the camera is garbage by today's standards but that's expected.
Ultimately, it's easy and reliable enough for someone who's interested in tech and likes to tinker, but I cannot recommend it for (to use the canonical example) my mother.
on a laughably small subset of devices
>and install LineageOS or something to keep getting community updates indefinitely.
false and only partially true for an even smaller subset of devices
For the lineageos support, you usually need to wait a bit but that's not really an issue since it's likely the manufacturer is still making updates while the device is pending support.
