Well using it now for a week on a 7+. Does pretty awesome job and doesn't seem to be glitchy or buggy. But there is a problem using my G Home app which doesn't allow me to use it and won't enable WI-FI to setup my G Home Mini again. Also some of the apps does seem to be not fully supported on it but anyways it's okay. But I would anyways go back to 12.3 since this is my only device available and I can't just left my G Home not seted up. Will try different option 'cause the OS itself is okay.
Good to hear. Sounds like the experience in general of some apps not working for various users. It’s a matter of being able to live without the apps if not critical to everyday use.
