Android

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 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.

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!

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.

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.

Larger, swappable battery. Squeeze for assistant

• Removable battery
• Ambidextrous button placement
• Screws instead of glue where possible
• USB4 + desktop mode

IR blaster

I enjoyed the squeeze to activate assistant on Pixel 2 XL..just felt right. I even configured it to activate flashlight when I needed a quick light.

One without a damn camera, I swear to God most of the price goes into having "quality cameras" I never end up using.

This list was created a few years ago.

Some things have been implemented but not all.

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.

true background process management and battery

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,

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.

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.

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.

Really would love a dedicated camera button that acts as a soft shutter release. Or a button in that position that's programmable.

Ability to use the screen as a display through the USB port so I can debug a lot of my systems at home without needing to carry a monitor around.

I'm on a Fold 4 now and I do love the novelty/oddity aspect of having a folding tablet.

But I would love to see the return of IR blasters on most phones and sliding phones for physical keyboards.

Foldable display - They are still way too expensive!

Metal case - I just loved the heavy Samsung Omnia metal case. It made it unbreakable and grippy!

Today my wish is for an internal pihole instance running on the device.

Better system font/typeface selection and a way to install new ones. I know it's a petty gripe, but the default android options are few and terrible.

Headphone jack. 5in or less screen size.

Hackability

A Silent/Vibrate/Ring switch like on the OnePlus phones, headphone jack and a easily swappable battery.

Does the alert slider counts as a niche feature? Very few brands provides this.

I just want a new Droid with a slide-out keyboard

I've had every one of them until the Droid 4 and they never released a new one
