LG X Charge: Unable to install all contents. 1 code: 400

Hi there Turlagh. This issue is caused when trying to update or download app on a slow internet connection (Mobile Data or Wi-Fi). So make sure you have a working internet connection. The error is very frequent in slow networks so try to connect to a different Wi-Fi or use Mobile Data LTE/3G. After connecting to the new network try to install/update your app.

Is 31 Mbps slow?

[Victor21]

Hi there. No that is pretty good. 

Go to Settings >> Apps >> All >> Select "Download manager 

Clear Cache and Data 

[Turlagh]

Didn't work.

[Victor21]

Understood. Please try the following. 

• Go to Settings >> Apps>>All >> Scroll down and Select "Google Play Store"
• Select "Uninstall Updates"
• Open Google Play Store and try to update or download the app
