Build me an Android app for Samsung phones that lets me control refresh rate and a few power saving tweaks from one place.

I want a simple app where I can switch between normal, adaptive, and high refresh modes, set different refresh limits for battery saving, and choose separate settings for the main and outer screens on foldables. It should also show a live refresh rate monitor, let me set per app refresh behavior, and include screen off options like turning on power saving, disabling autosync, and using a quick doze style mode to improve standby battery life.

Please also add a few extra tools like battery protection controls, animation speed and scale adjustment, quick resolution switching, and a status bar network speed toggle. Make it feel like a real phone utility app, not a developer tool. Support Tasker and app shortcuts too. If you need to check current Android or Samsung details, look up the latest docs online first.
