Recently I've had some problems with my Galaxy S3 Neo.. I semm to cannot change the language of my keyboard after allowing a useful app to be Service enabled on the Accesability tab. It seems that my phone doesn't want to allow switching keyboard language when I turn some app's Service of Accesability on. Why's that?! Someone help!
Can you let us know exactly what settings you're changing on the phone when it doesn't allow you to change the language of the keyboard? If possible, please provide a screenshot of the settings you're adjusting.
