If I found out a TV required internet access to function, I’d return it to wherever I bought it next day.
Luckily I have a old-ish flatscreen that doesn’t require internet but does have a netflix and other channels I can setup if I want. The Netflix client is so old it won’t connect to their servers any more. That’s OK. My Roku still works.
A long time ago, Google stopped doing updates on rooted phones. It’s why I stopped rooting my phone. Doing Android updates by reinstalling the latest release every couple months was a PITA. Also, Google finally got the Restore from last Backup working to the point that I didn’t have to rely on a backup utility that required rooting my phone. Ah, the early days of Android.
Not being able to rely on RCS from rooted phones makes sense security-wise. You can’t trust what’s attached to that message. It could be a code injection hack.
