Well, the limitation aspect depends so much on what you intend to do with your phone. If you want to experiment with your device, consider Android. If you want a phone that simply does the job as described by the manufacturer, consider a new iPhone.
Three years ago, I wouldn't switch to iOS even if you gave me all the iPhones produced since 2010. Now that my life has changed a bit, and that I don't have much time to customise and do experiments with my device, I won't switch to Android even if you give me all the latest flagship android phones on the market. I highly praise the person who invented the roter concept as well as the braille screen input on the iPhone. These two are truly life saviours.

For turning on the speaker, I've used an app called Auto speaker. It detects your ear like on iPhone, when you hold the speaker near your ear, it will turn off the phone's speaker. But when you put the speaker away from your ear, it will automatically switches to phone's speaker for you again. I don't use it right now, since I know where to touch to turn on the speaker when calling.

Hello to all. Anyone here have experiences with the one plus line of phones? I had Samsung phones but hated how slow they were with updating.  I have been somewhat curious on how the OnePlus 6 t is. Really enjoyed voice assistant on the samsung S8 I had but would not personally buy another Samsung phone until they get their crap straight about updating.

I've never had any problems with my Android phone. The numbers aren't too small here, and I have a phone with a pretty small screen. As for speaker phone, I don't know what that is, tbh. I just use headphones, or put the phone close to my ear, not sure what else there could be.
I've never used an iPhone, so I perhaps just don't know what I'm missing, but I'm perfectly happy with Talkback. That braille typing feature seems like it could be useful for some, but I live just fine without it. Honestly not sure why you find Talkback so bad. It does its job.
I have no real desire to ever try an iPhone. I like customization far too much to choose something so closed, no matter how perfect you claim the screenreader is. I'll probably get some rugged phone next, like Cat, or one of the phones supported by Lineage OS. We'll see. Either way, I bet I'll have more fun with it than I ever could with an iPhone. To each their own, of course!

Thanks for the responses.
One of the main reasons I use iOS is because of their iMessage and FaceTime apps. Android does not seem to have anything like that, so I will be out of luck. However, I’m starting to not care about their apps too much.  I don’t like how locked down the operating system is, and I want to be able to customize my phone.  On android all even be able to install different voices on to it. Because of this, I think I’m done buying iPhones. The next phone I’m getting will be an android, which will hopefully be in the near future. When that happens, I’ll let you guys know how it turns out.

Just to add to the conversation: I'm currently running android 8.1 on a galaxe j7 prime, sansung. The keyboard here is different, because you can, and need to, double tap on each letter or number before they appear on the editbox of whatever app you're writing on, personaly i find this a lot better than dragging fingers.

hi
the good thing about Android phones is, when you get root access You're unstoppable. From adding the functionality similar to stereo mix on windows, to giving your cheep old phone the benefit of having stereo speakers.
personally, I've never had a single problem with the phone app. I'm not sure about all the phones available but mine has Large buttons for Dialing.
if you're looking for a powerful phone with a reasonable price Try Nokia Devices. I think all of them are part of Android one. Some of them have this surround audio recording which is called ozo audio And it's awesome

I'm happy with my pixel 2 xl and i got it about 4 months ago. I used to use an IPHone and i get peole criticizing me for swithcing but i like the flexibility android offers as opposed to IPhone.

@Austingrace: Since you were asking about OnePlus, my OnePlus 5T is a fairly good phone, which was a bit frustrating when I got it first because of many unlabeled buttons and Talkback 6 wasn't deployed yet on Android Nougat, but I learned to deal with it and things have goten better since I got it.
The one thing that didn't evolve in a good way with Oreo is that the OnePlus dialpad became really hard to use with Talkback, and it is still the case today. So you may likely want to replace the dialler if you get a OnePlus, and the cammera app if you intend on using it.
Otherwise the phone goes smoothly as you would expect, though I feel Talkback may lack a bit in smoothness  by itself compared to VoiceOver, but that's probably due to the way it handles inputs. Nothing too annoying though, but you will feel it if you come from an IPhone.
I can't talk much about the 6T and it's under-screen fingerprint reader, but I have read some reviews saying it quickly becomes easy to find even with closed eyes.

18, on huawei and honor devices, you need hold volume up and volume down buttons to turn on and turn off talkback
