Released in 2018 and built on the Exynos 7885 platform, the Samsung Galaxy A7, A8 and A8 + smartphones have already left the two-year window of mandatory Android OS updates, but thanks to the efforts of an enthusiast, these “oldies” received the latest version of the One UI proprietary interface – One UI 3.1. With Android 11 included, of course.
An unofficial assembly of One UI 3.1 for these models was ported from the Galaxy M31 by a member of the famous XDA-Developers forum under the nickname VDavid003. It is called TreeUI and is installed on models with an unlocked bootloader and third-party Recovery.
As with many unofficial builds, TreeUI has some bugs. For example, the standard camera application does not work (but any other similar third-party programs from the Google Play catalog do work), face unlock and flashlight dimming do not work. But otherwise everything works, and the shortcomings are gradually being corrected. So, for example, in the version 0.9.4 beta, the NFC inoperability in the Galaxy A7 has been fixed. The update size is relatively small – about 2 GB.
