I've found several apps that stutter when scrolling. I even set force peak refresh in developer options, and things still stutter. There's lots of issues with this phone. I'm almost ready to RMA mine. Seems like it's hitting everyone on reddit.
Just a follow up. I installed the QPR1 beta last night which I knew worked fine on my P7P. This morning during my regular wordle time, the phone froze and rebooted. It's also depleting battery life like crazy this morning. Something is amuck.
