# Common problems

## Copy of hosts file failed on Android 9+

Latest versions of Android use read-only `/system` partition.
If you are using Magisk as root solution, ensure you enable the systemless hosts module then reboot.

## Nun hai espaciu abondo na patición

Try changing the target hosts file in preferences to `/data/data/hosts` (or `/data/hosts`) and apply AdAway again.

## Nun furrula n'Android 4.4+

Try changing the target hosts file in preferences from `/data/data/hosts` to `/data/hosts` or `/system/etc/hosts` and apply AdAway again.

## ¡Nun bloquia los anuncios na aplicación XYZ!

Some hostnames may be missing in the provided hosts files from the Hosts Sources or the application has bundled the images to provide ads without accessing the internet.
You can log DNS requests (Menu->Log DNS Requests) from AdAway to find out which additional hostnames have to be blocked.
Add the suspicious hostnames to your own Blacklist by long pressing the entries in the Log and report these hostnames when you have verified them in the Forum Hosts Inbox of hosts-file.net.

See https://github.com/AdAway/AdAway/wiki/ProblematicApps to get a list of known applications that have problems. Otherwise, find out which hostnames are needed and add them to your Whitelist under Your Lists and report them to the bug tracker of AdAway.
