You can remove a language pack to free some storage space. Follow the steps below :
- On the tablet's homescreen, from the right edge of the screen, slide your finger left and select
Settings > Modify the PC settings
- Select Time & language > Region & language
- In the Languages section, select the language you want to delete then press Remove.
When a language is set as main language of the device, you can't delete it straight off. First of all you should define another language as main language so that it becomes a secondary language. Once you have done this, you will be able to delete it.
