All modern wallets work like that to preserve some privacy with good address management.
One seed phrase can generate almost unlimited number of addresses, but you can still use previous address for receiving coins if you are getting regular payments from same source.
btw Ledger Live is bad piece software and I wouldn't use it anymore.

This is outdated model that is not used today, except maybe with paper wallets.

Realistic chances of this scenario happening in real world is minimal, but smartphones are generally a privacy nightmare so it's best not to use them when you want to maintain privacy.
Good old mobile phones still work fine if you want to call someone, receive calls and send/receive sms messages.
If you want more than you can use some of the mobile OS options you mentioned.

GrapheneOS is best you can get for privacy & security if you want OpenSource software on your smartphone that is updated frequently and it follows Android updates.
Note that GrapheneOS works only with Pixel phones, they can be found very cheap and they have several years for receiving updates.

PS
Don't expect to find perfect working solution.
There is pros and cons with everything.

Ma daj, budimo realni, ide se u programirano samouništenje, sa ili bez bitcoina  
a u u zadnjih nekoliko godina sam naučio sam da su SVI političari lažljivci, trojanski konji i lažni spasitelji.

Yeah I see now you currently have around 2% of bitcoin hashrate, that gives it a bit more credibility so I decided to test your app.
What I found is that you and your pool are probably based in Russia because all offers I can see in P2P tab are in RUB currency and only Russian banks are available in payment methods.
This can be problematic for users in rest of the world... I also didn't see any option to trade with with cash (maybe I missed it).

You are wasting time on Trustpilot and you wont achieve anything like this...
I don't know why you keep ignoring my question about creating flag (type 2 or 3) against pst.net, but I went ahead created my own type1 flag so anyone can support it:
https://bitcointalk.org/index.php?action=trust;flag=3198

Don't worry, Sandy Bridge has it's own bugs and flaws, and if you apply all fixes they slow down processor speed a lot  

Sorry but you are wrong about this.
Do better research what TRUE RNG is and how it can be generated, I won't go offtopic with that anymore.

It's not that vague or hard at all... just roll casino dices enough time and you have it, and something similar can be done with hardware devices.
If something can easily be repeated and reproduced than it's not really random.

I know, and they are doing it on purpose (probably)  

Prototypes of new devices?
That sounds interesting and I know people who would be interested in participating some kind of beta testing program.
Even sharing .stl files for 3d printing and option to assemble our own devices would be a good idea, something like DIY Passport

Nice.
I see lot of people having a problem to find good open source mobile wallet for Bitcoin, so I will download and test how Envoy works.
In general I can count on fingers all Android Bitcoin wallets, and most of them are not good.
Good mobile wallet should be open source, with option to run full node and option to connect with multiple brand of hardware wallets, or to work standalone.

But you won't use that sd-card all the time, not even near like you would use it in camera, phones or other devices, so chances of getting it corrupted in next few years is minimal to none (unless you operate centralized exchange cold storage).

Choice of Android Bitcoin wallets is very limited but I think that Blockstream Green wallet ticks most of the boxes, it is open source, it has ledger support and I think that taproot is supported, but better check that yourself.
Ledger is bad hardware wallet choice in so many ways so I would just ditch it and replace with better open source alternative device.

I know this coinjoin implementation is controversial, but It's amazing to see what Trezor has been able to do with this ancient old device 
This is first ever hardware wallet in the world and it's still kicking in 2023, almost ten years old.

Can people test and report bugs only for Envoy app even if they don't own a Passport device?

I think they are using industrial grade micro sd card that are like night & day compared to regular consumer garbage sd cards.
Anyway, you shouldn't really only on sd cards, you should always have backup phrase in multiple places, written on paper or even better on stainless steel plates or washers.

If it's not a secret, can you say what font are you using?
I think you might want to think about slightly changing font type (or spacing) when using bold parameter (if that is even possible).
It's fine for most numbers but letters are merging for me and it's not easy to read all of them, that can be a problem when someone want's to verify BTC address.
I think I have a solid eyesight, but other people could have even bigger problem reading than me  

Another strange unreadable result from previous post after I refreshed page:

I appreciate your efforts, but from my quick testing I see that I can enter anything I want in email field, so this is acting more like additional passphrase.
I don't see any real benefit of adding real email address, and it can only hurt newbies who (by mistake) could generate keys while being online.

Any random generation and mixing several sources is not really creating true randomness (based on my research).
Using something like good old casino dices and calculating last word is much better option in my opinion, but one downside is much slower process.

I wouldn't recommend anyone using this tool until we see code review or audits from security experts, but it should be fine for experimental purposes.

Why don't you add option to choose different countries without opening world map?
I had small issue and I didn't know how to return to main page, and then I found and clicked ₿ symbol in bottom right angle.

All-in-one platform and mixing everything together doesn't sound like a good idea to me.
I guess there are no many offers for trading right now, so temporary no-kyc during beta test period doesn't mean much either.
btw you should add link for google play store in first post, bith links are redirecting only to apple store.

I am sure you don't have real mining farms and ASIC devices, so can you name the mining pool you are affiliated with?

What do you mean? Did you received ledger wallet from betnomi in some of  their giveaway or you got it from some other source?
I saw them changing PCB's all the time, and to be honest I don't trust their integrity check process very much, as well as their closed source devices.

I meni je stiglo, ali Bitcoin može lako biti i još jeftiniji ako onaj prevarant Musk nastavi sa prodajom i ako ga ostali nastave pratiti.
Jedno je sigurno, nikad nije dosadno kad ste u crypto cirkusu

You can always encrypt all messages on your own and send them to other members, but they would need to have decrypting keys to read them.
If you want to share private confidential information you shouldn't use anything without encryption, but for casual talk it's fine to use forum messages and you shouldn't be concerned about that.
Note that not all encryption is made equal, and I don't consider telegram encryption is good.

New patch already?
What happened with previous one you worked on for adding 2FA functionality in forum?
If this one is done in your free time than I don't mind, but better look for other more serious issues to fix

I know, but I was a bit lazy to replace this and all my other images after imgur incident, even if I know there is nice tool to do everything much faster.
Anyway, image is replace now, but it's nothing special just random chip that is not really important for the context.

I don't really care about EAL numbers so much since nobody can verify this for closed source secure elements.
Hardware wallet can have highest possible EAL rating and it can still be total crap.

I can create my own trust rating but it means nothing, similar like difference between EAL7, EAL6 or EAL5.

Sounds like a scam to me, all this money just to get some ''certificate'' of security, and there is no guarantee someone wont exploit it, only guarantee is signed NDA aka silence.
