Hi, sometime doing upgrade also will make our important data wiped or removed from our phone. Therefore we suggest to do backup before doing upgrade or hard reset, also at Lenovo S820. Unfortunately data at internal memory will not easily recover once they has gone. Although you can try to use some recovery applications from Google Play Store, but sometime they can not help to recover it.

Hi, you should download important applications at your Lenovo S820, but please remember, Lenovo S820 only have 4GB internal memory, some memory will use to save the source file of operating system and also same space to save cache. You will get warning or trouble to download if your free memory left is around 150-200MB. The update process from Google Play Store will be trouble and sometime the icon at status bar above display will show always download and not finish. Please try to remove or uninstall not important applications, then make sure the internal memory free space is more that 400MB, it will make your phone work normally.

Hi, Saya sudah berhasil Upgrade ke KitKat dan bisa menggunakannya, TETAPI saya merasa RAM yang berjalan kok semakin besar dan kinerjanya semakin LAMBAT & Loading LAMA jika membuka beberapa menu ringan.
Bagaimana Cara Mengembalikan / Downgrade ke JellyBean sperti Awal beli ?
Mohon jawabannya, saya sangat memerlukan. terima kasih ^_^.
Hi, sorry reply in English. Lenovo S820 have 4GB internal memory and also have 1GB RAM. Basically this is fine for running several applications for multitasking, but if you have many applications run together which some of them as background process then, the RAM will be limited as well, and will run more slowly because your Lenovo S820 need to make sure which applications can automatically stop to serve new other application for run as foreground. Please also consider for performing hard reset after upgrade Lenovo S820 to Kitkat operating system.
