Hi, basically you can not downgrade your Lenovo S820 using OTA like you have done for upgrade. if your phone already have Android Kitkat but some problems happen, then please try to do hard reset, because maybe some installed applications are not compatible with new operating system version. If you do hard reset, all data and installed applications will be removed and you can download new version of that applications which may compatible with Kitkat from Google Play Store.
I have lenovos820 what is the solution if the home key is not functioning?
Hi, have you ever to install any 3th party home launcher? If yes, please uninstall it first. Sometime wrong setting with additional home launcher will can make navigation button not work properly. You also uninstall some other 3th party tweak applications. If you home button still can not work, then you have to do hard reset or reformat, but this steps will make your important data and installed applications wipe or remove. After hard reset your Lenovo S820, you have to re-setup again from beginning including install important applications that you need to use.
