Still, I prefer 2 physical slots. Some phones also have Dual SIM + eSIM, where 2 of them can be active at a time.
My current phone has Dual SIM + SD. I have all three populated, on of them with 9esim adapter. Removable eSIM. Easy to replace, and stores multiple profiles.
As for the second thing: https://www.androidheadlines.com/2016/01/hands-on-with-the-saygus-v2-smartphone.html
dual sim slot phones were very common in some markets where you needed to have multiple carriers. It’s a lot less common now that eSIM exists, but before then it was a common thing for the EU version of a phone to have dual sim slots when the NA versions were only single sim.
I currently have four eSIMs on my phone. I would love nothing more than to get rid of the last remaining physical SIM.
Ideally, also get rid of the whole slot to improve water resistance.
I would MUCH rather they focus on optimisation and power efficiency. My work iPhone can easily last two days on a single charge, three if I’m not really using it that much, all the while giving me all the processing power I’d need to run high-quality games on it. No Android phones comes anywhere near this and it grinds my gears.
All I’m saying is: different people, different needs.
