Tested on Pure Nexus w/ Pure Nexus dynamic gapps. This should also work with Open GApps. (And I guess Fake Nexus, though I think the camera works well out-of-the-box on that one...?)
On (most?) current Nexus 5 Nougat ROMs, attempting to take a photo via Google Camera with HDR+ will just take a regular photo. (The included stock camera doesn't even have an HDR+ option!) The "fix" is to downgrade to an older version (2.8) of Google Camera.
Problem is, that's kind of annoying. In addition, the Play Store will keep trying to update it to the newest version unless you re-sign. Not good!
So I made a flashable zip! Just pop it onto your SD card, flash in TWRP, and the proper Google Camera will be installed, signed with a custom key to prevent the Play Store from updating it.
NOTE: This does not fix the video recording issues, only the HDR+ not working. You still need to use stock camera for videos.
