"failure_singnature_not_verifiable" is displayed on iPhone X

Anyway, do I have to wait to see the version up of the NEM wallet app?

Same thing happened to me on my IPhone 6. I reported the problem months ago and no solutions have came my way. I even had the private key, but it doesnt back up to that wallet.

There are similar symptoms, do not you think?
If that is the case, I’d like a note that “Please use after testing with a small amount” when using.
I am in trouble if I intended to transfer it to a safe wallet, the most dangerous.
Since then, I am afraid to use other wallets as well.
I quit recommending it to the acquaintance until this matter is resolved.
I am waiting for an answer.

After that, while I was fiddling with various things, it became the following state.
1, I turned off “Touch ID” in APP setting screen.
2, even face authentication ceased to work at startup, it was only possible to enter the password.
3, At that time enter the password and press confirmation, the application drops as well.
4, I could not even log in and I was discouraged.
5, after 2 days from then casually start up the application, if you try typing the password, the application will not fall and login successful!
6, I thought well, Account name - Menu - Export When I push the confirmation, I had a 2 - dimensional barcode this time though I had fallen before!
7, I showed the public key and private key for the time being, and immediately pasted it to the notepad!
8, I thought that I can retrieve NEM now, I tried remittance, but it did not change that I got out “failure_singnat ure_not_verifiable” at remittance.

Those who have wishes, please.
What will I be able to save here?

In point 7. you paste your private key.
Could you confirm it’s 64 length or 66 length with leading 00?

The private key is 96 characters.
At the beginning “9f” the end is “1d”

The public key is 64 characters.
At the beginning “d8” the end is 30

is. Does this mean you can not?

This mean private key is corrupted and can’t be used.
Should be 64 or 66 length with leading 00.

I think that it is a problem when it is impossible to recover though secret key could be acquired.
I’d like you to fix it quickly with version upgrade.

I’m trying to reproduce the issue on a new device. If more information on the exact circumstances in your case come to your mind, please let me know.

@thomasoehri
There was nothing special.
I will explain the flow again.

  1. IPHONE X is 11.2.1 (15C153).
  2. I installed Wallet(1.1.4b5) on my mobile
  3. The password was made with 8 alphanumeric characters.
    (At this stage I was logged in by face authentication
  4. In account creation, I made it as “Mimi” with Japanese hiragana.
  5. It was my first time to use Wallet.
  6. 1 NEM was remitted on the same day from the exchange and reflected.
  7. Since it was relieved, 500 NEM was transferred completely and reflected.
  8. I also thought about taking a backup because the move came without any problems.
  9. When you select “Export Account”, the application terminated.
  10. I tried many times but the application has ended.
  11. I was giving up for a while and was looking for information.
  12. I got here the other day.
  13. I removed the face authentication and I proceeded to the export screen.
  14. I got my private key.
  15. There is still an error when sending money.

I will reply if there is a question.

If I say that you can not use that secret key even though I got a secret key
I think that there is no meaning of the secret key system itself.

Also, you can not remit money due to key error of backup purpose
I can not accept it.

I think that it is just a black hole that you can deposit money and you can not send money.

Improvement and correction, as well as key acquisition, we strongly hope to be able to recover.

There is a problem that the application rarely crashes in cooperation with face authentication. I think that there is a possibility that the secret key will be broken at the time of the crash.

@thomasoehri
Should I give up and remove Wallet and regroup it?
Or maybe you should continue to have it upgraded as it is?
I am bothering the storage method because I purchase NEM again.

@mimi
Leave IOS wallet as is. Maybe @thomasoehri will find solution for this.

New funds send to new desktop nanowallet https://nem.io/downloads/ and do wlt file + password and private key backup before you send it there.

understood.
Leave the application as it is until there is contact.
The current NEM moves to the wallet of the PC and uses it.
I sincerely hope to recover quickly.
For developers. I think that I am busy but thank you

The last answer tomasa 06/10/2017 after that he ignores me! he will not answer !!!

As far as I know Thomas is working for new IOS wallet version with some improvements.

Just to make sure, after 2) where you installed the wallet, were you first asked to create a password before being able to do anything else, or were you asked to enter an existing password?

@thomasoehri

What is the matter of the problem with IPHONE X?
There is no contact at all after that.
How long should I wait for Wallet to stay like that?

It is a small amount, but it is an important asset for me.

I am waiting for a reply.
