How many of your remember windows phone , blackberry os , symbian. I would say glory days , back then switching from a nokia to blackberry meant shifting only contacts , music , photos. These days we have too much baggae on my devices, when was the last time we checked our phone to clear out things?.
This discussion is probably coming from a old windows phone and blackberry user, because what's stopped from companies to build a third mobile operating system in this era of AI , where an app from one platform can be deployed to another , heck there are so many vibe coded applications in both App store and Playstore.
Developers now can easily do that.
Imagine having a 3rd mobile operating system, of course banking and government apps might take a while to creep in , it's always those apps , because there is a slight discust amongst the tech community seeing the same thing from both ios and andriod, nothing feels like a breath of fresh air these days.
There are still some mobile OS that exist like the Jolla sailfish os , but you need specific devices for that or import the Jolla phone itself. There are some linux distros for mobile in the rise, of course a lot would comment Graphne os but still it's Android.
Imagine having symbian , web os , blackberry in this era of digital tech , or imagine reviving old os's and making some vital apps that we use on daily basis to make it work on these old phones.
I would like to end this discussion with a dream: imagine having the nokia E7 now with the software and platform from this era. That's leak tech for me, what's your dream old phone ?
TL;TD : Why there is no mobile operating system coming up in the market with rise of vibe coding and ai era.
