I have been having this problem from quite some time now (And frankly I don't remember since when).. Whenever my apps are getting updates from the Google Play Store, my mobile becomes painfully slow and lags majorly. It like as if you are using Jellybean on a device meant for Android Eclairs! My system is neither rooted not modified. I had the same problem even on 4.1.2 so it is not the firmware issue. My Note II has Kaspersky antivirus installed which checks every new and updated app. I thought it may be because of this so I uninstalled the app but still no effect Toggling Power Saving Mode On/Off does not make any difference either
I have no idea what is causing it and it is really troublesome.. I have A LOTT of apps and sometimes it updates almost 10 12 apps in a go which is really irritating with the lag!!
Have have chosen any option that is causing this?? Or any app??
Please help me with this
