The POCO F1 from Xiaomi has been the surprise release of the year, as it shocked the Indian market through its insane value factor. The device has grown to be immensely popular among users who want a strong performer but do not want to spend too much on a phone. As an additional plus point, Xiaomi has generally been supportive of the third-party custom development community, allowing the POCO F1 to become the enthusiast's choice as an affordable flagship.
At the end of the day though, the Xiaomi POCO F1 runs on MIUI, Xiaomi's custom UX skin on top of Android. While MIUI sees regular updates for features and stability, some users would prefer getting rid of it and running AOSP on the phone instead. If you are among those users, but you still want the MIUI 10 camera, you can now use the MIUI Camera Port by XDA Member AEonAX. This port brings the MIUI 10 Camera app in the form of a Magisk zip for Android Pie-based AOSP ROMs. Do keep in mind that the app is considered to be in beta, and there are a few documented bugs at least, so you may want to install it alongside another camera app.
