A custom ROM could be the most important part of your aftermarket device when wanting to be away from the stock ROM that your device comes with when it’s pumped out of the factory. Custom ROMs require you to install a custom recovery. Once you boot your T-Mobile Samsung Galaxy S6 smartphone into that same recovery, you can choose to upload your ROM zip file.

Once flashed, it will replace your stock ROM for a custom ROM of your choice from the list. You can expect the custom ROM to be on the smartphone up until you flash the stock ROM back over the top. That means each time you turn the T-Mobile Samsung Galaxy S6 smartphone off and on, it will display your custom ROM.

Some common reasons people choose to flash a new ROM on the Galaxy S6 include to increase the privacy, update the firmware, remove the stock apps and make it faster, extend the life of the device, walk away from the factory skins, using open source software for the fun of it, and personalizing your ROM to have the look you want it to have.

Here are some of the best custom ROMs that are available for the Samsung Galaxy S6 smartphone.
