I am happy to share that I found a relatively reliable gcam version for the Redmi Note 7.
What seems to be working reliably: Back Camera Photo, Front/Back Camera Video
With some other modes, e.g. Front camera photo, it freezes sometimes, but you can still tap on other modes and unfreeze the app.
The ROM itself works quite well. It's fast and battery life seems good. So thanks!
I'm currently on march build and I use only this phone since then. (april OTA updates ruined system - google play services didn't work anymore. It's my only phone, can't play with testing, because I need it every day. )
I practice as always clean install + smallest gapps package (currently Nikgapps core).
To the point: Camera related issuesSuggested fix to use certenly camera app and custom config I don't see this as a appropriate solution! I encounter camera related problems on every step, doesn't matter which app I used. Tested with open camera, proCam X and furthermore Viber, Noteblock (pdf scaner like app), ... always the same.
Camera freezes or is lagging. You never know, if picture will be captured and later saved. Roughly say it fails on 50% or more of shoots. Absolutely unreliable and from my point of view a critical bug.
Suprisingly even after a fresh reboot is not always reliable. When it fails, I just press home button and close the app - wipe it from last opened apps. Then I repeat task. Maybe then works, maybe not. It's extremely annoying try 5 times or more for succesful saved image (doesn't matter in which app). You miss important moments...
