Today, we will show you the steps to install Lineage OS 18.1 onto your Xiaomi Poco F1 (beryllium) device.
The Xiaomi Poco F1 has a 6.18 inch Full HD Display. The design of the Smartphone might be liked by some, but to others, it might be disappointing. This is primarily due to the plastic build. Anyways, the Xiaomi Poco F1 is powered by a Qualcomm Snapdragon 845 chip coupled up with the Adreno 630 GPU and with massive 8 GB of RAM. Coming to the Cameras, the device has a dual-camera setup at the rear. This consists of a 12 MP and a 5 MP camera sensors. The Poco F1 has a 20-megapixel front-facing camera. The device runs on the MIUI. This MIUI is specially designed for the POCO F1. At last, there is a 4000 mAh capacity battery powering this device.
Lineage OS 18.1 with Android 11 Features
Among all the custom ROMs available for our device, Lineage has been among the oldest player. In its early days, it was known as CyanogenMod and now this ‘lineage’ seems to have been rightly carried forward. Based on the Android Open Source Project, you will be able to welcome a few handy customization options to your device. The ROM isn’t known to offer a plethora of features, rather it maintains an equilibrium with the stability front.
As far as the latest LineageOS 18.1 is concerned, it is based on the latest Android 11 that has just been released. This in turn translates to the user getting blessed with some noteworthy features. These include a separate Conversation section, OneTime Permissions, and the new Notification History. Likewise, there has been the introduction of Chat Bubbles and a native Screen Recorder. The Media Player has now also been moved to the Quick Settings with some handy Media Controls options.
