Hey, I edited my comment, thanks. I checked my phone specs and I actually have the 7 pro, not the T. I've had it for over 3.5 years so I rounded up.

I have the same phone too! It’s still going strong even after 4ish years.

I feel the same way. Plus the quality of the phones seem to have gone down. I have a OnePlus 7T and it feels solid. The OS still runs smoothly, I drop it all the time and it doesn’t break, although I have it in a silicon case which I’m sure helps. I got my Mum an 8T and it feels less sturdy. Her screen has some significant scratches, and she is far more careful than I. Given this and the increasing price, I’m also unlikely to get another OnePlus phone.

I’ve had the 7 pro for like four years and I’ve never had any software issues.
