If you are looking for the best Android 7.1 Nougat for LG G3, you may want to try the latest CrDroid ROM, which is one of the few Nougat ROMs available for the LG G3. Fortunately, this ROM is available for most of the LG G3 models including T-Mobile D851, Canadian D852, Korean F400, Sprint LS-990, and Verizon VS-985.
Upon trying this ROM, I am pretty satisfied with its performance and battery life. The only thing NOT WORKING on this ROM is video recording but still photos work great and this is something all Android 7.1 Nougat ROMs have a problem with until it is fixed in the near future. Otherwise, this ROM is definitely recommended as a daily driver with a working data, voice, bluetooth, etc…etc…
And yes, you will be able to enjoy Android 7.1’s faster performance and enhanced battery optimization. I was able to get my top score on Antutu of 55,000, which is about 5% higher than what I got with Android 6.0.1 Marshmallow. In real life testing, games also run very fast along with fast UI.
Not only that, CrDroid ROM comes with its own CrDroid Settings that allow you to fully tweak your status bar, navigation bar (like add PIE Controls), and a slew of customization that actually makes it better than a real Pixel phone. Better yet, add Google Assistant along with Pixel Launcher to make it identical to a Pixel phone.
This ROM will definitely renew the life of your LG G3 for at least another year as you will be able to enjoy Google latest and best. If video recording not working doesn’t bother you, definitely give it a test drive this week(end) and do let me know what you think!
