Are there any small Android phones comparable to the size of an iPhone 12 mini?

You can try searching by dimensions with gsmarena's phone finder. Looks like there's not a ton of options, mainly the smallest galaxy s phones and some other fringe options.

The smallest Android phones around would be the Jelly series from Unihertz.

Depending on your stat requirements and if your carrier supports one, it might work out for you.

I went deep down this rabbit hole late last year, trying to find a decent Android smallphone.

All the options available are fringe. The least fringe option is Unihertz which someone else has already mentioned. I've never had one of their phones, a friend who had once told me that the build and software quality is what you'd expect given the price - you'll probably be looking for another phone in a year. Also I'm not sure who the aesthetics of the Jelly phones are for, but it's not me.

Someone else mentioned the Ikko Mind One, when I was looking that hadn't released yet but was supposed to come out in January. The emphasis on AI is off-putting, but the form factor is fascinating. I worry that flip camera wouldn't be durable. Props to them for trying something different.

The one I nearly pulled the trigger on was the Bluefox NX1. It might be ok, there was very little info at the time, might be some more out there now a few months later. https://aiphor.com/

^ that Aiphor site has a bunch of other smallphones that are basically NIB e-waste. Most are quite old, and these things will never get an Android version beyond what is on them now, so you should probably avoid them unless you're somehow ok being stuck on an Android version so old it had a food-based codename. Also a lot of these phones have fake cameras - one of the camera apertures on the back is real, but the rest are just plastic doodads mimicking the arrays you'd find on a decent phone. I'm guessing maybe this can be a selling point for teenagers in third world markets?

There's also the Palm Phone. No relation to the Palm Pilot. I so, so wish this thing didn't suck, it looks amazing. But the battery life is supposed to be hilariously bad, the Android is super old, yadda yadda.

Then if you go back 3-4 or more years there were some Nokia "throwback" models released, but they were way low volume so you aren't likely to find any left in decent shape.

I kept the p9p I had gotten a few months earlier, and then the free pro access to Gemini kicked in, so now I'm probably locked in to Pixels for a while to keep that going.

There are other phones from a few generations back that might get you close - I had a few Sonys and always really liked them. Xperia I ii and Xperia 5 iv, IIRC. At various times it's looked like Sony would finally throw in the towel on the US phone market, but sure if they have or not. But the phones had been getting bigger, and losing the unique throwback features like the notification LED 😢

Sorry I don't have anything better to report. If someone finds a legit smallphone let me know! I had been thinking maybe the smallboye would be my at-home lightweight wifi unit, and then take the pixel on the road.

Do you mean the 12 mini? The 12 was a fairly standard sized phone.

There should be some fringe options you can get, as @cdb mentions, the GSM Phone Finder is really good at this. I recently learned about a real odd option called the iKKO Mind One but its less like an iPhone 12 mini and more a normal iPhone 12 with the top third chopped off.

I've hunted a lot for this over the years. You can look at unihertz phones, or one-off phones like the upcoming Clicks Communicator, but camera quality and security updates (let alone full Android updates) are always going to be a problem coming from anyone but the largest OEMs.

You can also look at running a custom ROM on older small phones like the Xperia Compact series (now quite old). Hardware and software support are even more of an issue here, and depending on your carrier, you might not even be able to connect a custom ROM to voice-over-LTE or 5G. Band support is also an issue, since a lot of custom ROMs don't have great modem drivers.

The iPhone SE1/SE2/SE3 all still get security updates, and you can pretty easily buy replacement parts for each. The 1 won't run a fair amount of modern apps due to the iOS version, but the 2 and 3 are cheap and still run the latest iOS. For me, the 2 and 3 are slightly bigger than I'd like, but it's at least close to usable.

Flip-style folding phones might be worth it if you actually want the giant unfolded screen. But price, brittleness (they often develop gaps or cracks along the fold within 1-2 years), and camera quality are massive issues. Not to mention the fact that a giant unfolded screen defeats 50% of the attraction of a small phone for me; I want a phone that fits into my pocket comfortably, yes, but I also want a phone that I can fit into my hand comfortably when I'm using it!

In case you want to cheat off of my own personal answer: Eventually I got an iPhone 13 mini. When this thing kicks, maybe I'll just give up smartphones entirely.

Bought the Zenphone 10 with the same intent of looking for a smaller Android couple years ago.

Its a pretty average phone, but I stopped caring about specs and more about useabililty. Been satisfied with it so far.

How do you feel about the Clicks Communicator phone that's coming out later this year? I pre ordered myself one.

But I also have a small phone (pixel 5) which I've been using since 2019 and have no plans to get a bigger phone. Maybe Galaxy s25 since that is the smallest current phone but I'll try the Clicks Communicator when it comes out.

You might try the phone selectors at versus.

A quick Google tells me the iPhone 12 has a 6.1" screen, and measures 146.7 mm tall, 71.5 mm wide, and 7.4 mm deep.

The Samsung Galaxy S26 comes in close, with a 6.2" screen, and measuring 147.0 mm tall, 70.6 mm wide, and 7.6 mm deep.

Alternatively, the Google Pixel 9a also has a 6.1" screen, and comes in 152.1 mm deep, 72.7 mm wide, 8.9 mm deep.
