Spark has been working without issue and I don't mind the app at all. I like the unified inbox for all my email accounts but I'm looking forward to receiving my pixel 6 pro in another few days and finally being able to use the Gmail app reliably again!
I hope that you enjoy your new phone.
The issue seems to be related to the oneplus 9. I had the 7T before and Gmail worked fine but with the OP9 Gmail has issues no matter which rom you use which is weird.
So maybe a kernel issue or something from google itself trying to promote their phones.... or create problems to oneplus.
You use the boot img from whatever build your on,if your gonna flash it. Patch in the magisk app.And you can always use any oos A11 boot.img and fastboot boot magisk_patched.img. This allows su access on boot. Then go into the magisk app and install root permanently. This process backs up stock boot img for next time as well. Many ways
Android 11 yes stock oos A11. Yes flash with the evo or fastboot boot that same image from Evo not stock if your on Evo . Then gain permanent root in the magisk app. This backs up untouched Evo boot.img
I had this happen randomly after rooting, doing a manual restart worked for me.So just a heads up everyone, I follow the OP instructions extremely carefully everything installed without a hitch but I have randomly encountered reboots into Qualcomm crash dump mode completely at random I wasn't doing the same thing either time and nothing I was doing was root or you know f'ing with the rom at all so idk what up but better bewareish
otherwise absolutely FABULOUS rom, I mean on the go mode etc it's just awesome other than crash dump mode....
