Reminds me a bit of HMD's KaiOS feature phones but this is apparently Android?
I think that was made obvious by the big thing on the marketing website scroll about checking cricket scores.
They're not even the only country in Asia where cricket's big.
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.
I couldn't find specs for this thing but from the picture it looks to be about the same size as the original iPhone.
Touch 4G: 102 x 62 x 11
iPhone: 115 x 61 x 12
The Samsung Z Flip is probably your best bet if small size is the most important factor - though, er, slightly more expensive than the HMD!
Z Flip 7: 86 x 75 x 13
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.
I go to places where there is very little, to no, risk of being robbed. This is good.
