On few Galaxy A12 you can’t install Smart View and Screen mirroring on a12.
The opposite app you can install for that is “Smart Things” on the galaxy store. I wondered why a12 doesn’t have those features (Smart View & Screen Mirroring) but a10 and a11 has it. I hope Samsung will release those features for a12 on One UI 4.
Any method that requires wifi isn’t a work around for the Smart View service built in to older phones. It does not need wifi to work. Instead of using Chromecast , Smart Things does the same thing the key distinction is you must have wifi.
It’s also silly about Samsung A12, you can use my A12 as a wifi Hotspot to give TV access to the internet, but not share my phones screen with the same TV without “extra” “**bleep**” it seems like Samsung got complaints from the cell providers because we could use OUR phones to watch app content on a TV instead of burning up tethering or Hotspot data allotment.
