Moi? I use currently a NOTE 20 ultra 5g. Probably my second best phone, I only hate the fact it’s so massive (I miss being able to use just one hand for my phone) and the mediocre battery life for someone like me that watches a lot of videos. But the S pen is so handy those few times you need it.
I’m currently using a Samsung s21 ultra, and it’s kinda meh. The compass is not bad, it’s horrendous. It used to be offset by say 90 degrees, but nowadays it seems more likely that it’s a random number generator from 0 to 360 degrees, making any maps app bacically unusable unless you look at road markings, and other buildings to guess which way you’re facing. The main camera has over time developed a hardware issue that makes all pictures always out of focus, unless you hit the phone on a hard surface to dislodge the focusing mechanism. From a software standpoint it’s a good device. No major bugs, and it’s pretty stabile.
My favorite phone was a used Samsung s6 as it felt kinda “flawless”. Battery was good, camera was great (for the time), and hardware was pretty awesome. It was a great phone while it was still getting updates.
