How to Downgrade Your Android OS Version
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.

If you have a Samsung Android phone that you wish to downgrade, you’re in luck. Samsung phones are some of the few phones that can be easily flashed with an older version of the operating system.

Download an older version of the stock firmware for your device and save it to your computer. A simple Google search will help you find it. Also download the Odin flash tool to your computer.
Extract files from both stock firmware and Odin and launch the Odin tool. Click on the PDA button in the tool and select your extracted firmware file.
Deselect the Repartition option in the tool. Checkmark both Auto Reboot and F. Reset Time options in the tool.
Power off your device. Press and hold down Volume Down, Home, and Power buttons together for a few seconds. When asked, press Volume Up and your phone will reboot into the download mode.
