After the update I haven't been able to properly store more data into my data file because the privacy apps assume it's a virus trying to get in. I just want the old update back without the security update so that way I can add more data to my data file.
Turn phone off
Hold the volume up and power buttons simultaneously.
Once you see the Samsung logo, release the power button, but KEEP HOLDING THE VOLUME UP button until your phone is in recovery mode. Clear the cache partition, run the repair apps option (if available), then reboot your device. Test it out. LMK if this helps! GL!
