Why You Need a Custom ROM

Custom ROMS are extremely unique and can take your Android experience to a whole new level.

First of all, ROMs like these will optimize your phone’s battery as well as its performance. Smartphone users often complain about their battery running out before long, and this is one way to rectify this situation. Plus, you get complete administrative control over your device, allowing you to run several programs that you may not have been able to otherwise.

With the control you’ve achieved, you can install the latest updates, hibernate annoying or time-consuming apps, and much more! The level of customization with these ROMs is also unprecedented; you get the ability to do things like enable and disable the navigation bar, customize and bars, overclock and underclock the CPU/GPU, and gaining access to third-party themes.

What You Should Know Before Buying a Custom ROM

Custom ROMs do give Android users an immensely unique and more useful experience according to their needs. Still, it must be remembered that they’re not officially provided by mobile vendors. Such ROMs are created, developed, and updated by the Android community.

The above fact means that if anything goes wrong with a phone after installing a custom ROM, there’s no one you can blame. There’s no guarantee or refund available, so you’re stuck with your decisions. This could also greatly affect the resale value of your phone, even making it impossible to sell off at any decent price. But it’s worth installing a custom ROM for the benefits they offer.
