I’ve had my phone since 2021 and never had any issues. I accidentally let my phone update to 16 last week but hadn’t had any issues until last night when I was using my phone like normal and it suddenly crashed. A bar of pixels appeared at the bottom of the screen , it freezes and turns off. I was then stuck in a loop of crashes and could never use the phone for more than a minute or so, even in safe mode. If I let it sit on a crash on boot, the phone got so hot I feared it would damage hardware so I sat it on an ice pack. Suspecting the update was the fault as I hear Google take after Apple these days, I flashed 15 back onto the phone (which wasn’t easy for someone who doesn’t know what they’re doing) , but it crashed 5-10 times on the initial setup. After persevering, I eventually made it to the Home Screen and could start to get my apps back but it still crashes basically every other time I use it. I have no idea if this is still a software issue or not. I spoke to Google support and they just told me to take it to icracked and they may charge me as much as I pay in rent or more to fix it as I don’t have warranty anymore. I’m considering a replacement but now I don’t know if I even want a new pixel phone. Is anyone else having the same problem or can anyone offer some advice? Thank you in advance.

Did the update brick my phone or is the hardware finally dead?
