All of my random trolling aside, I do use my phone for quite a bit more than I care to admit.
I rely on not only my banking app and such, but I also require the Microsoft Authenticator app for my Azure AD MFA stuff at work. If I can’t log into my email and such for work, that’s a huge problem. Most MFA solutions have some kind of SMS option as well, so that could be a workaround there.
I watch a lot of YouTube on my phone and the web app is nowhere near as usable as the dedicated app. Same goes for Twitch, Mixer, and others that I watch. I also enjoy watching some Disney+ before bed on my phone and that’s not even available in the browser on Linux at the moment.
Chromecast. Good ol’ Chromecast. I use this all the time. I have a Google Home Hub (the one with the display) on my nightstand that plays movies or YouTube while I sleep. This is essential as I have a hard time sleeping on many nights and this helps to center me and fall asleep. Without that functionality built into the apps I use, I’d be much less well off.
Cloud storage integration is also a very important feature. Knowing that my Android or iOS device is backed up is really helpful. Also, using things like Google Photos, OneDrive, iCloud, etc. ensures that when I take a picture, it’s saved in many places and I don’t have to worry about losing that awesome profile pic of McGee.
One last thing, CarPlay and Android Auto. These are 100% essential for me as I spend a lot of time commuting and having maps, podcasts, music, audiobooks, phone, messages, etc available to me while I drive is not only a luxury, but a requirement of any smartphone platform.
Those are just a few, but I’m sure there are more than that. I’d love to hear if anyone has solutions for these. Also, no, I don’t care about privacy, so that argument is kinda wasted on me.
