Simple unofficial (this app is not in any way affiliated with the Apple Inc.) Apple TV IR remote control for Android phones and tablets with built-in IR blaster (Samsung Galaxy, HTC ONE, LG G2 etc). It's also compatible with other Apple devices with an infrared receiver (some MacBook Pro, iMac, iPod dock etc). The purpose is not to replace the original remote, but it is handy in emergency situations (original remote is lost, empty batteries etc).
★ Works with Samsung phones and tablets with built-in IR-blaster ★ Works with some phones with Android compatible built-in IR-blaster and Android 4.4 KitKat (like HTC ONE). ★ You must point your phone’s IR blaster directly at the TV. Usual working range is 5-10 (max ~15) ft. ★ No additional hardware is needed. ★ No need to jailbreak your Apple TV. ★ No full screen ads, no push notification ads or any kind of similar pop-up ads!
With some phones in power saving mode or with almost empty battery the IR blaster might not work or range is less then 5 ft.
If this app doesn't work with your phone then feel free to e-mail me (your exact phone model and Android version). Then I can try to add support for your phone/tablet.
