Re: Remove 2FA in Electrum and use Standard Wallet instead.
I was unable to recover the 2FA on Android just as Text posted. The error I got was different but it was an error. I tried it the first and second time with the same error. Test is using a mobile phone for it.
I also tried to import a 2FA seed phrase into the android version of electrum to see how it works and got the following error. 
I cleated electrum's cache to see if it solves the problem. It didn't and I got the same error again.
After that, I cleared all electrum's data from my device and then imported a 2FA wallet. It worked.
It seems that once you create your first wallet in electrum, it no longer allows you to import a 2FA wallet.
