The Stock ROM (Mobile OS) is the Most Stable ROM released by the device manufacturers depending on the device model and Android version. However, the Stock ROM don’t offer many customizations or features for the device.

In this case, you may experience battery issues, network issues, camera issues, missing features, lags, overheating, slow performance, and many more. But whenever you switch to Stock ROM, you can quickly fix them all.
