My wallet is indeed a bitcoin-core but not the concept that you have fixed on it, for your clarity mine is a "Bitcoin-core wallet app" as I mentioned from the beginning.
No, it doesn't look like your image. Mine looks completely different.
I downloaded it from "https://bitcoin.org" ... wallet ... mobile

This image is exactly the wallet from which I have been asking for help;
it is simply a ~~Bitcoin-core wallet app~~ that works on smartphone with android operating system.

Then you do NOT have a "Bitcoin Core" wallet... "Bitcoin Core" refers specifically to ONE wallet... it is a full node client and it does NOT run on mobile phones.

What you have downloaded is a mobile wallet application for your phone, created by an independent application developer and most likely has no relationship with the "Bitcoin Core" project... Available here: https://bitcoin.org/en/wallets/mobile/android/bitcoinwallet/

This particular wallet is also known as "Bitcoin Wallet for Android": https://play.google.com/store/apps/details?id=de.schildbach.wallet

It's been 23 days without having my BTC, please can you certainly help in solving the problem? or do you know anyone who wants to help? Thank you very much for everything.

Ok... knowing it is Bitcoin Wallet for Android, we can try some things... have you tried refreshing the wallet using: "Settings -> Diagnostics -> Reset block chain"

Also, have you made a backup of your wallet file using: "Safety -> Backup wallet"? Huh

Edit: note that you can always import your bitcoin wallet seed (a list of 12 words you're given when you install the app) to another bitcoin wallet so you don't have to use that particular one.

That won't work with Bitcoin Wallet for Android... it uses (encrypted) wallet file back-ups... not 12 word seed mnemonics. However, if you have the encrypted backup file and know the encryption password, there are scripts which will decrypt the wallet file and show you the seed mnemonic contained in it.
