Google Camera With (Potrait Mode) + Setting [Tested on lg v20]
XDA Senior Member Arnova8G2, best known for his work on porting a Snapdragon-optimized version of Google Camera app, has modified Charles_l’s Camera NX 7.3 app to work on non-Google devices. his app brings a functioning Portrait Mode feature to devices such as the Xiaomi Mi 5/5s on LineageOS 15, OnePlus 3 & 3T on OxygenOS 5, Moto G5s Plus, and reportedly even the Samsung Galaxy Note 8 running the leaked Oreo beta ROM.
Portrait only works if you have a human face on the frame. It wont work on inanimate objects
Both BSG and Arnova apks, only Arnova has a higher likelihood of crashing than BSG in my experience
And my phone is LG V20 (H990DS)
some devices maybe not support with this app.
system req : Android 7.0, snapy 820 and higher
