So you want to install custom ROM on Realme X smartphone? Then we got you covered. No more searching around because we’re going to list all the best Custom ROMs currently available for the Realme X. This phone was first announced in May 2019 by Realme and released in July 2019 with Android 9.0.(Pie) which was later upgraded to Android 10. (Q). Custom ROMs followed soon after and the community of developers continues to release many more for this model.  

Custom ROMs have been around for a while now and are very popular. That’s because of the open-source nature of the Android OS. This means any developer can modify the code, recompile it, and re-release for a wide variety of devices. Such as the Realme X and others. Interested users can install Custom ROMs but first, let’s explore the pros and cons of custom ROMs.

Pros of Custom ROM

  • Install custom themes, wallpapers or widgets which might include modified colors and icons, startup screens.
  • Be able to root devices of course (check our post on Android rooting).
  • Less bloatware e.g., removal of manufacturers’ pre-installed features.
  • A mishmash of modems and kernels, selected for best battery life or performance. 
  • Options in menus ie reboot to recovery or fast boot mode instead of just rebooting the device normally.
  • UI tweaks i.e place on/off controls in the status bar instead of using a widget.
  • Extra system-level features i.e. in-built tethering 
  • Upgrade to a version of Android that hasn’t been or won’t be released for your device. 

Cons of Custom ROM

  • Non-Stock Android-based custom ROMs are often a bit experimental thus might lack driver support.
  • Custom ROM can include any apps from the creator wanted and that’s bloatware.
  • Custom wallpapers and themes may not be what you want; most ROM developers aren’t designers.

There’s always the possibility of bricking your device when installing a custom ROM. Make sure you know what you’re doing when you flash a custom ROM. Also never use a ROM designed for a different device and that’s why we’ve prepared a list for you. Flashing a custom ROM just like rooting will almost certainly void your device warranty. So be sure to check before you proceed.

The artern97 kernel features a host of enhancements to the device that include, better memory management, UFS optimizations, WireGuard support, and many more. It’s worth mentioning that the artern97 kernel has been tested together with LineageOS 16 and it does not support OPPO’s stock ColorOS, despite that, it’s likely to work with other AOSP-style ROMs.
