Pixel 3A. Constant bugs, camera would stop working or had a long delay starting up, system would randomly stop responding, constant crashes, lock screen would bug out preventing you from unlocking the phone. Dialer would bug out preventing you from answering the phone. Random reboots. Screen scratched really easily.
Phone crapped out about a month before warranty expired, wouldn’t boot any more. Luckily, it was still in warranty and they returned the full price.
