Remove incongnito from chrome

 

[webworkings]

The only way I know of to disable Incognito from the phones Chrome browser is to ...

1. Go into "Settings".
2. Tap "Apps".
3. Locate and select "Chrome".
4. Hit the "Disable" button.

However, as far as I know, this only works 'sometimes'. Different manufacturers, different OS versions, etc., play a part.

Your only other option would be to not use the Chrome browser and install a different one. Possibly even uninstalling the Chrome one. Personally I prefer FireFox.
