I went through my late teens as the initial smart phone boom was happening. I had a Motorola q that could get TV channels and had a keyboard. I had the enV that flipped open. And many androids/blackberries that I loved for their unique form factor and functionality.
I have never balked at spending money on a phone and for a long time i felt locked into generic flagship devices. With the debut of folding screens I feel like my appetite for unique devices rekindled. I think the power of android lies in its diversity of implementation.
So what features and functionalities would you choose over the next flagship release?
Apparently most of my requirements/desires fit this. I require an unlocked bootloader, because I need root to not throw my phone through a window. An amazing camera would be needed as well.
I REALLY, REALLY would like a removable battery, IR blaster, small form function, a headphone jack, and a rear fingerprint reader.
I'd like a phone with no camera facing me, and physical hardware switches to completely disable the mic, camera, battery, and entire modem. Not some software interrupt and lock. I mean, the switch is circuit ground for these circuit blocks. When I select OFF, it means real world "this thing does not exist any more ever" until I turn it back on.
It would be interesting to have a modular rear camera with a removable lens, removable IR filter, along with public documentation and the full API for the sensor. This would open up an enormous range of applications. I would mostly mess with astrophotography more.
I know some phones had already did this, but I always liked the idea of support for using your phone as a TV remote. The phone has replaced so many pieces of hardware that it feels silly that TV remotes haven't been replaced yet.
I also specifically wish Chrome supported extensions on mobile. Firefox does it. Why can't the biggest browser do it?
There are some niche phones with a thermal camera, would love to see more of that. Thermal modules are getting smaller, cheaper and better all the time and the main producers like infiray or guide are offering modules that seem to be clearly targeted at the smartphone market.
I'm still discovering new uses for my thermal camera and I wish I could have it in my pocket all the time. The obvious uses are finding gaps in your house's thermal insulation or finding devices that draw a lot of standby energy. But you can also use it to find studs in your walls, find things that have recently been used, like cars in a parking lot or chairs in an office.
I was looking into smaller form factor phones awhile back, and an interesting feature I noticed some of them had was a programmable button.
I don't know that programmable buttons on phones are that niche, but it's certainly not common either so far as I'm aware, so this super simple feature would be wicked imo. I'd also really like if more phones just stole Motorola's gesture interactions (e.g. quick twist for camera, firm double-shake for flashlight, etc.).
Also, uh...Speaking of small form factor phones, I don't know if that counts as a feature, but it's one detail I'd like to see come back, or flip phones with separate screens (clunky, sure, but better than the screen eventually creasing imo).
E-Ink would be nice, whether integrated as part of an OLED/LCD screen, or a separate module that goes over the top.
Most of the things that I use my phone for don't generally need the full colour display (text isn't that expensive to display), and I wouldn't mind trading that for vastly better battery life that you can get from e-ink, but having the option to use both is probably the best way to go.
An IR transceiver wouldn't go poorly either. It's not something I use much, but it was handy to have when I did, whether to send things around, or to just use my phone as a remote for televisions and things.
Late to the thread but here's my thoughts on everything I'd like in a phone. Having just a few of these would make a huge difference in how much I'd want the phone.
Hardware:
Standard features like a 3.5mm jack and MicroSD slot.
Multiple USB ports (especially on tablets)
Thunderbolt port
Here's a simple idea: Instead of making a thin phone with a massive camera bump, you make a thick phone with the camera flush with the back, and use the extra space for a bigger battery?
User-replacable battery
Modules like the modo mods
Battery passthrough when charging
Upgradable SoC, RAM, internal storage???
Software (here lies my hopes and dreams that will never be manifested):
Starting off simple, a feature that lets you manually limit how much you charge your battery.
Manual over/underclocking controls for the CPU
Separate WiFi/data toggles
More control over how big or small icons and text is
Easy root access with app makers not getting all "you sus" over the fact that your device is rooted
Niche or not, I want an SD card slot that actually fucking works. Like, yes, I can move files to it, but I can't actually install apps to it. There's the "move to SD, but that doesn't matter when the app files are still stored on the internal storage.
I want a Galaxy Fold style phone, but the external screen is eInk. Have it set to always show the book I am reading. This will let me read in bite sized pieces.
Slide out physical keyboard, notification LEDs or some form of cool lights, a dedicated camera shutter button, and a scroll wheel / touch pad like what used to be on the blackberry or like the LG KE970 I really liked that.
I really miss notification LED's though, always on display is good, but a little light is going to use far less battery and be immediately apparent from across the room by the colour what app the notification came from is.
I miss the IR blaster. Being able to control my TV and other set-top boxes was amazing. Now that functionality has been replaced by each manufacturer having their own control app that needs an internet connection and all your information. Bring back the IR blaster!
Max 4 inch screen, IR blaster, physical keyboard with speed dial settings for buttons, form factor like the Xperia x10 mini pro, headphone jack, cameraless, LED with customisable lights for different notifications, bonus - built in projector, satellite phone capability,
Then also, FM radios. Most Android phones had them up until a few years ago, when Apple stopped shipping iphones with the feature, to push more people onto iTunes.
I'm not a huge radio listener. But having the functionality during an emergency is invaluable. There was a really bad storm in my country a few years ago. Me and my family had no power and no internet for nearly a week. I would listen to my battery powered radio to get weather updates and to find out what the situation was like elsewhere. I don't understand why that same functionality can't be implemented in phones.
Besides that, removable batteries, sim card and SD card slots.
Whenever I buy a phone there's two function I look for that is getting phased out: LED indicator and a 3.5mm audio jack. It's why I have a Sony Xperia. The thing is there's no user configuration for the LED indicator. You either need to pay for a third party app or unlock the bootloader and install a custom firmware. I would love if a flagship phone had an LED Indicstor that was customizable. i.e. Blue for a text, Red for an email, Green for battery at 80%+, etc.
Native Bluetooth GPS support. I do mapping for OpenStreetMap a lot and the built in GPS modules are just too bad for that. Currently I have to use an app to get my Bluetooth GPS connected. But sometimes this app fails and the built in GPS takes over and ruins my logs.
An OEM FM/AM transmitter. I would love to be able to playback music directly to any old ass car. Or even use it as a very short range walkie talkie with the right program.
A swappable battery. I could buy a few batteries and never be out of power. I could replace the battery on an older phone without pretty much having to replace the phone itself.
This is going to be such a stretch and I doubt this would ever happen, but if you could get a decently sized camera sensor on the back of a phone and a mirror less style lens mount...I would sell my DLSR in a heartbeat.
I loved the IR Blaster on my old Galaxy S4, was really fun to mess with the TV's in public places with it sometimes and was also pretty useful at home as well!
Basically an Asus Zenfone 9 with a removable battery and an Sd card. Also, make the front like Sony phones - larger bezels on the top and the bottom of the display and house stereo speakers and front camera there instead of a cutout.
Phone upgrades.

Solar panel in screen. Sapphire glass. Smudge and germ
Plastic back and a removable/user replaceable battery.
Yeah yeah I know it "feels cheap" but honestly I LIKED when phones were made of more plastic. Now they're heavier and both sides are breakable. Like, the metal backs were fine, but apparently metal backs suck for NFC and wireless charging so instead of giving us some classy Nokia Lumia style plastic they went with glass backs.
Also I keep my phone in a case because otherwise the back is so smooth it shoots off the couch if someone walks across my apartment. It's legit only in the case to add some friction.
By Android's standards IR blaster. Had them in my last 2 phone and man is it nice to turn the volume down on a TV which is too loud in a public place like a Hotel Lobby or a Restaurant
Slide out controller, like the Xperia Play. I've gotten super into (at least the idea of) SBC handheld gaming, and there's just nothing quite like the Xperia Play now. Sure, there's bluetooth controllers, but I'm not a big fan of bluetooth, and the majority of the bluetooth controllers make portability a pain rather than it being a sleek package.
A full physical QWERTY keypad on my 3rd hand Blackberry Bold (in 2013) was the best thing I had seen on a cell phone. I wish full physical QWERTY keyboards would make a comeback.
Headphone jack. I've used multiple LG phones before, currently using the LG V60 and seems like Sony is the only way to go in the future, unfortunately.
A phone built somewhat like a desktop PC. All parts replaceable or even upgradable. Choose the components for your needs and budget, or buy a pre-built.
But let's get to more standard smartphone concept.
On software side, no bootloader locks, or easily unlockable bootloader (not requiring internet) and root access that could be enabled in developer settings.
On hardware side:
IR blaster - Control your AC, TV, etc.
Front-facing stereo speakers - could give a better stereo sound. And bezels aren't a big problem. Actually they can be positive as you can hold your phone better with them.
Headphone jack - Obvious. Would be cool if it had mode for composite output, but that's quite extra.
Dedicated fingerprint scanner on front - I had this on Moto G5s Plus. It allowed awesome gesture navigation, much better than using whatever on-screen.
Trackpoint - Early Androids used to have that. Would definitely be useful with large screens.
FM, HD Radio, DAB, DAB+, DVB-T2 Lite receiver - Radio is pretty useful. AM would also be nice, though you would need external antenna better than cable from earphones. I think FM radio is the minimum here.
TV Receiver - Just like with radio, except now you're saving much more on mobile data.
Camera with optical zoom - We've been there with Samsung in the past. But I understand it makes things too large and heavy.
Projector - We've been there with Samsung in the past, again. I think it was done pretty nicely on the projector part with Beam 2. It didn't even add much thickness. Just the rest of the phone was meh.
3D Screen
Pico Projector
HDMI out
Notification LED
Removable battery
The first smartphone I owned was the Lobster 700TV, Which as the name suggests had a digital TV receiver built in. The screen was too small to be practical, but I've always liked quirky features like that
Not really a feature of the phone, but a design theory. I want my small phone back. Not this "zenfone 9" size small. Like HTC One size small.
Make it bifold wallet sized, and ~1/2"thick.
These hugely tall phones where you can't reach the top third if the screen without dropping the thing are just annoyingly huge.
Then they make them so thin they can't fit a big enough battery for a full day use.
Beyond that would like an under display fingerprint sensor. Rear and side mounted always have issues with cases for me, and make it more annoying when using the device while it's on a desk.
I got a Samsung flagship mostly for DeX, even tho I'm enjoying the whole thing, I really wish desktop mode on Android was more easily accessible. Like 99% of the market doesn't even use the required USB C version for it.
As well as better app compatibility when going on a big screen, a lot of android apps just don't scale well.
The literal only thing keeping me on iOS/MacOS is the system wide glass transparency, continuity, and the battery life. I wish to Christ that Android/Windows/Linux would get their shit together.
My ideal system would be Android + Ubuntu with full glass UI and continuity between them.
