using android with IOS, will it add more accessibility?

I don't think so, no.

You might find different apps but I don't think anything drastic has come out on android where it's a game changer blind accessibility wise.

I think both platforms are now equally as good for phone usage, the only thing I'd warn you about is that if you get a basic android phone it might be hard to start talkback, but then again with android 12, I think it was, talkback should be startable by holding down both volume buttons.

Also, why do you need 2 phones? Is it just because you want to try Android?

If you're gonna get a budget Android phone and ya want the best when it comes to speed & power (along with spoken camera support), your best options are to either grab a Pixel A series phone or a Samsung A series phone (primarily an A36 or A56). Speed when it comes to the A16 & A26 may not be up to par.

Moto phones also work (as they use a stock interface) and also use Talkback via the Playstore unlike Samsung's version. If ya do by a Motorola phone, best to grab the Seeing AI appp from the play store or sideload a port of Google's Camera app (if the device ya get has a port for it), since the stock camera on Moto phones does not speak the distance of faces.

Just a thought, but a tablet might serve you better than a second phone, and would still let you play around with Android. I have used both, and would say they are pretty much both on equal footing, but can't say that there is anything on Android that is a game changer blindness wise, and I've found that switching between platforms is a bit of a headache as far as muscle memory, because I would be going to do Talkback gestures on my iPhone, and Voiceover gestures on the Android device, and obviously that is just annoying. Can you switch between the two? Sure. But is it entirely worth it? For me, no, not really.

I would recommend Pixel Pro, over anything else. I know a lot of people swear by Samsung, but for your first Android, plus coming from iOS, you will not be happy with a Samsung as your first Android device. If you want something that feels close to the way iOS works, but is different enough for you to experience Android, without such a high learning curve, Pixel is the way to go.
Pixel Pro would be best, because you get a more powerful device, with more features, a better refresh rate, and snappier UI. However, if you are on a budget, a Pixel standard, or a Pixel 'A' device – as mentioned above – should meet your needs.

I use my laptop with headphones for that kind of thing but if two phones works for you, why not.

Hello Ramy!
I don't recommend to get a low budget android manufacture.
if you really want to try and get the best android experience
get a google Pixel
I recommend go for the
Google Pixel 8 or
google Pixel 9A
that will be some price around $550
I do not recommend to get the Pixel 9 pro because basically its a flagship device to use as secondary device.

Android has come a long way over the years. The reason I, and others, recommend the Pixel to you is because Pixel is considered the iPhone of the Android lineup.
Does this mean that Pixel is identical to iPhone? Absolutely not. However, there are enough similarities, that transitioning between iOS and Android (on Pixel) is a lot easier than would be on other Android devices.
Some of the things that are similar are:
• touch typing
• magic tap*
• a multifunctional rotor**
• Customizable touch gestures
• many accessible apps that are also on iOS, such as Be My Eyes, Seeing AI, PiccyBot, etc.
*I do not know if magic tap is systemwide, or if it is application specific.
**Rotor is accessed a little differently on Android.

There are actually a lot more similarities, but I just wanted to list a few here.
Likely one of the biggest things you will have to get used to on Android, would be the angled gestures. These are really interesting, and I personally wish they were on iOS as well. This is where you would do a gesture like up then left to go home, or down and left to go back, for example.

Good luck with your purchase, and your journey into the Darkside, a.k.a. Android. 😆

I can confirm that my experience with an old s20 ultra isn't the best. Go for a pixel, the tactile design alone in my opinion is worth it (saw the pixel 8).
For me I honestly think that a setup mac android for a blind is definitely worth the try as google does most if not everything on the web with google messages and etc and adb and even android studio works on the mac.

I believe another user on here had a similar situation, within S20Ish device. They found that they liked Google's TalkBack over Samsung's TalkBack, and then had to go through the painstaking process of getting Google talkback installed on their Samsung.
Not trying to put down Samsung at all, but definitely do not think it is a good starter device for somebody coming to Android from iOS.

This might fit better in the old discussion about iOS vs. Android apps, but personally, using two phones has been a huge help for me. In my country, some apps—like a banking app and a travel/food delivery app—are simply more accessible on Android. The interface is nearly identical across both platforms, but on iOS, certain elements, like food menus, are clumped together in one continuous list.
For example, instead of displaying separate items, VoiceOver reads something like:
"Promotion! Salted egg fried chicken, 30k. Order favorite fish and chips, 20k. Order favorite."
To select an item, I either have to use screen recognition, or memorize its position and turn off VoiceOver, and tap—hoping I hit the right spot. I can’t entirely blame the app, though. As far as I know, VoiceOver's core codebase hasn’t been updated to properly handle modern UI elements. Sure, new features are added, but it’s like building extra floors on a crumbling foundation. That said, VO still runs smoothly in most cases, and I prefer certain apps—like WhatsApp and blind navigation tools—on iOS.
However, when testing newly discovered apps, I often find that the Android versions are more accessible, which likely ties back to the codebase issue.
Now, for a major hot take: I actually find the Rotor easier to use on Android. That said, the action rotor on iOS is way more reliable.
So, does having both phones improve accessibility? The answer is both yes and no—it really depends on the apps you use. But honestly, I’d still recommend having both if you can. After all, if we can afford iPhones, why not check out the other side's midranges, which is cheaper in comparison? That way, we can end the over-the-top Apple fanaticism that’s all too common in Blindy, LOL. I get it, this is applevis where blind apple users reign supreme, but misconception of android is way too much, it kind of fall into false information catagory. I once talked to someone who literally said that "I heard you can't even make a phone call accessibly on android", like what? LOL, I wonder who been spreading this information.

My first smart phone post blindness wasn't LG Optimus, running Android 2.2 "FroYo", or Frozen Yogurt. This was in 2010. I am happy to report that I was able to make phone calls quite well on that old device.
TalkBack was pretty much in its infancy at the time as well. 🙂

I don't know, I'm still nostalgic about the old talkback sounds and yes I loove these angled gestures as well, especially that talkback has a real passthrough gesture while ios has a 75% ish version of it.

Like the younger talkback had this prettyness that it's seemingly lost while chromevox still retains it. Okay, I know I'm weird there. But really, I generally love chromevox and would love to be in the complete ecosystem with these new chromebooks plus and a pixel. Like I can unlock my phone with my chromeos flex which macos still lacks for whatever reason and windows phone link got iphone notifications before macos which is... very apple in fact because they were Oh you have your watch for that. Of course now we have IM.

I think these are quite old nowadays, but they were some of the best designed Chromebook ever manufactured.
