About LineageOS

LineageOS is the most used and most trusted Custom ROM out there. It was started as CyanogenMod and known to be the first custom ROM or firmware which was able to make its way to some smartphone as pre-installed default firmware.

LineageOS is based on AOSP code and you will hardly feel a difference from stock Android. There are some third-party apps like Trebuchet, AudioFX, Clock, Dialer. Jelly, Eleven Music Player, Recorder, Snap Camera. All the apps are useful and there are no Ads in them. LineageOS comes without Google app or GApps, you have to install them after flashing the ROM.

Due to its stability and performance, many other custom ROMs use LineageOS code as their base, some of them are Resurrection Remix and crDroid.

If you want a daily driver with good battery life and performance, then LineageOS is one the best option for you.

About the Android 10

Android 10 is the latest version released by Google with a lot of new improvements in much-needed areas. With an increased focus on Privacy, the new Dark Mode and the improved Gestures, Android 10 brings a lot of long-awaited features.

Dark Mode

Dark Mode was a very requested feature and Google gave Dark mode in some of its Apps before. System-wide Dark Mode is finally here in the Android 10. It can save a lot of battery life especially if you are using an AMOLED screen. It also goes on your eyes.

Privacy Features

A more powerful set of Privacy features is not just necessary for the user but for the big companies too because of the hefty fines they are getting by Government.

The Permissions are now very strict and will ask if an app can use a particular thing like GPS or a Sensor every time, only when the app is open or it can’t use the Sensor at all. You can find the new Permissions manager in the Setting which will list all the apps using a specific sensor or service.

New Gestures

Android 10 finally brings a New Gestures system that can replace the traditional Three-button navigation system and Android Pie’s navigation bar.

Although the Gestures are inspired by iOS’s gesture (It is the same), the Gestures are now usable and are easy to use.

New Theming options

Theming options were found on Beta 2 version of Android 10 and are expected to come with the release of the Pixel 4 launch.

Focus Mode

Focus Mode Android 10

Focus Mode is a feature introduced to curb your Phone addiction. The main point of this feature is that you can select a bunch of apps that are distracting and you can stop them all for a duration of time. At that time, there will be no notifications and you won’t be able to use the app.

New Share menu

The New share menu is now ordered alphabetically and the suggested apps appear on top of the list. It is a big relief as the previous Share menu was a complete mess.

Live Captions

Live caption is a feature that will display captions on a video played offline or with the Video player. It looks like a very good feature for Deaf and people with difficulty in hearing. Also, it can come in handy at night when you don’t want to wake the person sleeping next to you.
