The LG Optimus L90 is one of the top Android smartphones right now, especially when it comes to battery life.So, there is no surprise that a lot of users on that great piece of hardware want to install some of the best custom ROMs for LG Optimus L90.
Viper ROM is based on the latest Lineage OS 14. The Android 7.1.2 build came with a lot of features and the ROM uses the Nougat kernel source update as well. There are a lot of different mods and tweaks baked into the ROM as well.
Though installing custom ROM improves the device’s performance and UI experiences, it makes the company warranty void and they will no longer be liable to provide updates in future [users can restore warranty by flashing the device with stock-ROM]. Make sure the device is rooted before going forward for custom ROM installation.
