This definitely sounds like a case of getting the wrong file or a corrupted download. I’d recommend using
download 1xbet apk for android which gives you the correct version for Ghana and is updated frequently. Make sure you enable “Install from unknown sources” in your device settings before trying again. Also, clear any old versions or remnants of failed installs first—it can mess with new attempts. Once I did all that and used the link above, it worked like a charm. App performance has been solid, and the betting experience is smooth without lag. Hope this solves it for you too!
