I had this a while ago on one of my Android devices: an error 926 while downloading apps from the Play Store.
After searching, the only relevant solution I could find is in the below youtube video. These are the steps to resolve the problem:
Reset the “Download Manager”
Go to “Settings”
Click “Apps”
Click “All” (it will often not show up under “Running”)
Click “Download Manager”
Click “Clear cache”
Click “Clear data”
Reboot your phone
Reset the “Google Services Framework”
Go to “Settings”
Click “Apps”
Click “All” (it will often not show up under “Running”)
Click “Google Services Framework”
Click “Clear cache”
Click “Clear data”
Reboot your phone
For some users, just resetting the “Download Manager” might fix the 926 problem. I had to reset “Google Services Framework” as well. Others had to reset the “Google Play Store” app.
These were the circumstances I encountered the 926 problem:
Brand new device
Added Google account
Performed the first firmware updates
Added some apps from the web based Google Play Store
After successfully installing some apps, the device would show error 926
After fixing the 926 error, I installed all apps using the Google Play app which then went fine.
Esc: Back button; F1: Menu button; Home: Home button.
Really really cool!
