What is special about this? Does it cost $20? Is it a cheap smart phone (why do they call it a hybrid phone?) targetting India (mentioning of cricket)?
Apparently some other HMD devices (HMD 105, HMD 110) use "RTOS". Most likely their proprietary feature phone OS, don't expect it will provide an option for user-installable apps.
And it is indeed smaller than most smartphones. Apple never made a small smartphone, presumably because they need the big screen for their vending-machine-in-your-pocket to sell more content.
Apple struggles to sell budget models of their phones, everyone wants at least the standard version. Why would they try to sell an even tinier phone than the SE? No one will buy it. The Apple Watch is a tiny device with its own SIM but that's not a phone, it's a smartwatch so its really an accessory to your phone.
I mean, depending on what you mean by "small smartphone", the early models definitely count (3.5"-4" diagonal). They were huge screens for their time, but nowadays everything's a phablet so they look tiny by comparison.
Conversely, I am counting 6 persons (7 when including myself) in my direct close circle that do not upgrade because there is no Mini on the Apple lineup.
I'm not counting people that did upgrade but are spiteful of the forced size increase.
I'd have got one myself but iOS doesn't work for me.. I have several things I need on a mobile phone that are not available on iOS.
For me a phone is really an outside the house thing only. I don't use it at home to poke around on the internet etc, like most people do these days. I still have a real computer with a massive screen and keyboard. So a mini size is great for me.
On Android there's the ones from Unihertz but they take the "small" factor a little bit too far, and also their software support is absolutely terrible. And people often mention the zenPhone, I'm not sure why because it was never smaller than the Samsung S-series. It wasn't really a small phone anyway.
Reminds me a bit of HMD's KaiOS feature phones but this is apparently Android?
