New OS updates for your Android phones are supposed to bring new features and bug fixes. But this is not always the case. Sometimes an update can lead to more bugs than the previous version. Or worse, the update might even break features that worked great in previous versions of Android on your device.
These are some of the times when you might decide to downgrade your device to an older version of the OS, especially when that older version worked great on your device.
Unlike iOS devices, it is quite possible to revert an Android device to an older OS version. Many manufacturers have their own tools to help you with this.

If you have a Samsung Android phone that you want to downgrade, you’re in luck. Samsung phones are one of the few phones that can easily run an older version of the operating system.

Downgrade from other Android devices
As you can see in the methods above, downgrading to an older version of Android usually requires you to download a stock ROM and a tool to flash the ROM on your device. And when the ROM is flashed, you will completely revert to the Android version of your choice.
For phones that we have not listed above, you can easily get the standard firmware files and flashing tools from Google. Then just load the ROM file into the tool and you are ready to install it on your phone.
Downgrading your Android phone means that your device has an older version of Android OS. Once it is up and running, you can launch apps that don’t work in newer versions, as well as use anything else that is out of order and no longer works in new Android builds.
