How is everything? I hope everything is fine. We all know Google Camera/Gcam is cool. It can take a picture better than stock/default camera. If you want to use Gcam/Google Camera then this tutorial is only for you.
You can enable camera 2api from adb command but that isn't the permanent way and every time you need pc/laptop. Magisk module sometimes doesn't work always & custom recovery way isn't safe. So, I think build prop way is cool. If your device is Mi 8, Mi Mix 2, Mi Mix 3, Poco F1 then you don't need to enable this. Because camera 2api was enabled by default. You can check your device manual camera enabled by default or not. Download "Manual Camera Compatibility" app and check. If it isn't enabled by default then read this thread and enable. Before starting this tutorial we should know about Gcam. For Redmi Note 5 Ai/Pro (Pie) follow this tutorial: Here
❒ What is Gcam?
Google Camera is a camera application developed by Google for Android. It was initially supported on all devices running Android 4.4 KitKat and higher but is now only officially supported on Google's Nexus and Pixel devices. It was publicly released for Android 4.4+ on the Google Play Store on April 16, 2014, and removed from public view on Feb 17, 2016.
❒ Why Gcam is very popular?
When any device can't get portrait mode then Gcam/Google Camera giving us lance blur. After realizing the pixel device giving us accurate portrait mode better than other dual camera device portrait mode. Now Google released Google cam 6.1 only for Pixel device. It's portrait, night feature also cool. Google improve their Gcam day by day.
❒ Who ports Gcam for our device?
Gcam is ported by many developers but you should know about popular developers.
BSG: BSG, or B-S-G, is the main developer working on this port and shares his apks on 4PDA, a Russian forum for mobile stuff. Most apps from other devs are based on his work. BSG's apks usually work well on Xiaomi phones, but some of the settings/features included are not compatible with other phones.
Arnova8G2: Arnova8G2 owns the Xiaomi Mi 5, OP5T, and OP6. On top of porting new features and trying different things to improve photo quality, he makes BSG's work compatible with more phones (other Xiaomi devices, OnePlus, Samsung, etc). His versions usually come with better/easier to understand settings/menus and work better on phones that need extra fixes (eg: OP3/3T/5/5T).
❒ Install Google Camera/Gcam for our device:
(You can download any Gcam. If an app isn't working then download another app and install)
