LiveBoot is boot animation application that shows you the output of both logcat and dmesg while the device is booting up. Not only do people see it as a better boot animation than an OEM's logo, but it can also be useful as it can show you errors from these logs as they happen. The application is from XDA Moderator Emeritus and Senior Recognized Developer Chainfire and it has just received a couple of big updates for some of you who are running the latest software.
The big updates that were recently released are mainly for those on Android Q or Samsung devices which are running One UI. Version 1.81 was released a little more than a week ago and it brought with it some bug fixes with Magisk, the script it uses, the test button not working, and the new Samsung One UI Pie update. Then, a few days ago a test version of LiveBoot was released that adds support for the first Android Q beta.
Those who are looking for the stable update with various bug fixes can look in the XDA thread below or the Play Store for the update. If you're wanting to use the app on the Android Q beta then you'll want to grab the test APK from the linked post above.
