I tried kdeconnect and really liked it while I used it. Had a weird issue where my Google TV kept turning off. Every time I woke my phone screen up, my TV would turn off. Couldn’t figure out how to fix it so I deleted the app and the TV worked perfectly again. Only had kdeconnect on my Linux mint laptop and pixel phone.
Was a boost user until I heard about Voyager from another one of these post. Boost is good but Voyager is so much better.
