MIUI is customised Android operating system for Xiaomi’s phones. Earlier in the year of 2017, Xiaomi banned to install third-party themes on devices running MIUI. The company took this step to promote their own themes so that they can showcase the talent of their designers and developers. They only allow downloading and installing themes from the official website designer.xiaomi.com. And I guess that’s the good option for us, as we only get those themes which are tested and bug-free.
However, a few users won’t find those theme attractive, and they want to install a third-party theme on their Xiaomi devices. But while installing it, they may face problem and device will show “Themes from third-party sources not supported” error on MIUI.
