There was text in the title bar but this has been removed.
I've saved changes, looked at it in B4A Designer on the device and that's okay but when running the compiled program on the device, a grey title bar always shows (no text) and also not in full screen.
Any ideas how to hide the title bar programmatically or otherwise?
You need to also change these settings in the Project menu of the main code window. Those options in the designer are to help make sure you are working with the expected layout when the app is run. In other words, ideally they should match.
I want to have an app where you can stll see your battery and network etc. , but i just want the activity bar gone. The title is alreay gone, but the icon stays.
