Mi Remote Controller
Another option is the Mi Remote Controller. This app was made by Xiaomi for its Mi smartphones and tablets and works pretty good. However, it'll work with any other phone or tablet with an Infrared Blaster, not just Xiaomi devices.
That instantly makes it a decent option for those looking for a universal remote control for Android. According to the company, most devices with an IR blaster work great. If you don't have one, the WiFi protocol kicks in. Just make sure your phone and the device you want to control are o the same WiFi, scan for devices, connect, and you're all set.
It even works with TV Scheduling and other advanced controls. Give it a try today.
