Welcome to Vodafone Community
How do I erase device history on my Vodafone Broadband App? It lists all devices no matter how long ago they used the WiFi. I want to delete them?
On Android, you can do this from the Applications section of Settings. This is not going to be foolproof, because those settings are configured differently by the device manufacturers.
Settings> Device|Apps>Vodafone Broadband>Storage>Clear Cache + Clear Data
Some of the above will just look like text, but you can still click and it will drill down!
I have found this pevious thread. https://forum.vodafone.co.uk/t5/Other-broadband-queries/Router-factory-reset-doesn-t-erase-devices-h...
If you cannot delete the devices follow the last reply for Vodafone to take a look at this problem for you.
