I put my Pinephone back in its box about 6 months ago. Have they fixed the massive lag between touching the screen and it responding yet? That was the main reason it wasn’t usable for me.
In 6 months there have been tons of progress yes. Though I didn't have any issue with the touchscreen 6 months ago so your issue might lies elsewhere. You should try reflashing completely yours with Mobian or another well-supported OS.
