It's too darn big. I'd love another Nexus 4-sized phone.

Software updates. They are disguised as security and feature updates while slowing down your phone to make you buy the newer versions.

Under screen fingerprint sensors. Doesn't matter how old/new your phone is, they all suck. The one on my phone works... whenever it feels like it. That and OneUI sucks, but yk, custom ROMs ftw.

Under screen fingerprint reader (pixel 7 pro) . It's a downgrade from reader on the back of the phone (pixel 5). It's slower, less accurate, and worst of all, at night it often results in being flashed with a bright light.

I thought it'd be more convenient having the reader on the front, so i can unlock the phone without lifting it, but most of the time it's a nuisance because i doesn't work as well.

Can’t listen to music while watching a video or listening to a podcast.

its bootloader isn't unlockable, and custom roms don't exist for it anyway

In iOS how hard it is to glance the time and date while watching a full screen video.

The screen protector is peeling just a little bit around the edges, but it's put on really well, and I don't want to use the replacement just yet, but it's slowly ever encroaching and leaving more and more of a dead zone in an area I don't touch all that often, but when I need to I question whether or not it's time to put the new one on.

It's been like this for almost a year now.

Also no ir blaster, so I can't subtly mute the commercials when I'm at the in laws.

With the phone itself I miss a headphone jack (using an adapter USB c to 3.5"), no hardware keyboard, and no replaceable battery.

In general I don't turn my phone off often enough, usually only once or twice a week I should turn it off more often.

I wish I had customizable buttons for like... Flashlight, or you know... Whatever I want.

non-unlockable bootloader :(

(Samsung S10e, switching to Sony Xperia 6 soon...)

Lack of physical keyboard.

Being a flimsy piece of shit comes in second.

I'm aware how that applies to basically every smartphone from 2013 - today. Currently rocking a used Galaxy S8

Have had my S8 galaxy since release, and now various apps won't work on the OS. I'm being forced into buying a new phone at this point.

Not being able to install Graphene OS

i want a physical qwerty keyboard like the pro1x

It's not completely foss

After close to 6 years of use it’s reaching the end of its useful life. Unless there’s a catastrophic failure or something I plan to use it until it no longer gets updates, which should be some time next year.

About 2.5 years ago I left behind Android and went to the Dark Side. Bought an iPhone. It was frustrating to use at first because changing OS is a pain in the ass, but I got used to it and actually really like it now.

But I still have two big complaints:

There ought to be some kind of icon in the toolbar to show me I have unread notifications. I miss this very much from Android, which would show icons for the apps that have notifications. The Apple Watch solves this by having a notification icon, but I shouldn’t need to buy a separate device for that functionality.

I cannot stand that I can only go back by swiping from the left side of the screen. On Android the swipe in gesture from either left or right side could be set up to be the “back” action. I understand why this is, Android developed with a dedicated back button and thus has an OS-level back command, whereas iOS is highly contextual and you flow through apps and menus differently than Android, and it has no dedicated universal “back,” so swiping in from the left is back and swiping in from the right is forward. It makes using a large screen one-handed unnecessarily difficult.

My S20FE checks a lot of boxes but I miss a few features from my s8+, mainly the status LED and the heaphone jack. I also am not a huge fan of the fingerprint scanner, but it works well enough so meh. Removable battery, obviously everyone wanta that. I also wish the operating system could could install custom OS.

Generally: That I can't mount my network samba shares into local folders without rooting the whole damn thing.

That I can't force my device to stay in wifi if no internet connection is available (to access local network only).

Device specific: That sometimes volume control is very buggy while putting in a headphone jack and I have to navigate into sub-sub settings hell to set everything back.

Even though I turned it off, my phone will sometimes pop open the AI assistant after hearing something not even close to the "hey Google" phrase.

I also hate that the new AI system for the assistant can't even do half of the shit I used the old assistant for. Which is why I turned it off.

I dislike most of it, everything but paying contactless, making calls or SMS. I have a 2020 SE because it is small but I want a tiny dumb phone, being able to store my bank card on it to pay anywhere, and phone or SMS someone. The rest to me is useless, I very dislike it when I am somewhere and everyone is on their phone (mostly with the volume on 10 too), I don't even bring mine when I visit someone just to make a point how disrespectful it is when I am invited to your home and whipping out a smartphone.
