No space left for updating windows 10 mobile

[peter mathiasen]

My device is a Lumia 735 with Windows 10 installed.
When I try to install the newest version I get asked to delete 1.1 Gb - which I have done exept 0,01 Gb. Deleted all non Microsoft apps - cannot delete any Microsoft apps!

Tried to delete Groove, Maps and Weather, but I am not allowed to do that - and I still need 0,01 Gb. One Drive takes up 666 MB although the data is on One Drive!
Also I have deleted not used favorites in Edge, several pages in One Note etc.

Saved texts and e-mails will affect memory along with contacts.

I can't remember if the 735 has an SD card slot, yet sometimes taking the card out before updating helps.

Worst case, you will need to perform a hard reset of the phone.
This then free's up space from System.
