Helpful if you encounter new problems
Newer OS upgrades for your Android phones are supposed to bring new features and bug-fixes. But that isn’t always the case. Sometimes, an update may bring in more bugs than the previous version had. Or worse, the update may even break the features that worked just fine in the previous Android versions on your device.
These are some of the occasions where you may decide to downgrade your device to an older version of the OS, especially when that older version worked perfectly fine on your device.
Unlike iOS devices, it’s totally possible to get an Android device back to an older version of the OS. Many of the manufacturers have their own tools to help you do it.
