Looking for Alternatives to Android OS? Here are the Best Mobile Smartphone OS other than Android and its Forked versions

Mobile OS is very important when it comes to smooth operation, features, and task-handling capabilities. The Huawei controversy, where Google barred the Chinese-giant from some updates to the Android operating system due to a clash between the Trump’s administration and China, made it very clear that every major smartphone manufacturer must start developing its Android alternative operating systems.

Also, where more than 86% of the mobile OS market is occupied by Google’s Android, it is essential for smartphone manufactures to have their own operating system. Well, where there’s nothing wrong in having a device tailored OS, as it allows maximum flexibility and control. In this article, we are providing you the important reasons why we should look for Android alternatives and a list of best mobile operating systems.
