Camera is very unusable. Open Camera didn't worked for me, with footej taking one picture at a time is working (then you need to restart the app and some times your phone). Surprisingly is the whatsapp inbuilt camera the most stable.
With all due respect - are you a masochist or what? Why on earth don't you put this info in the OP?? It will save you tons of noob whining! About one of hundred will find this hereNo......... You should NEVER install gapps afater booting.......... This is what causes the issue the dude is having... Flash rom, Flash magisk, Flash gapps, boot. thats it. i dont have any idea on where you guys saw that you need to boot before flashing gapps.
If you are flashing a GSI, chances are the system partition isnt the full size, and then, AND ONLY THEN, you need to flash rom, boot (This resizes the partition), go to twrp, wipe data,cache and dalvik, then flash gapps and magisk and then you are ready to use the rom.
