Be carefull what animation theme background you use, it can lockup your screen, unless you remove and reinstall your cellphone's battery. Other than that the Google voice app is pretty neat with a alot of features, but I'm not using the app, my old Samsung Galaxy Note 3 has enough features I can handle. Some Play Store apps can hijack your phone settings and very difficult to reset after hours of trying, but it can be done. Anyway, I don't do alot of adding new apps to my cellphone anymore, because I have so many apps on my phone already. I actually uninstall alot of apps I really don't use on a daily basis, plus apps contains popup nuisance commercials. Downsizing my apps helps to keep the clutter down and save storage space for more important stuff. Eventually I want a new, bigger and faster phone.
