crypto wallet ledger

I was wondering if all Crypto Wallets have a backup phrase typically 12 to 24 randum words the system generate and which you use to restore your wallet. For instant NanonLedger S has 24 words while Exodus has 12 words / Backup Phrases. Is this a crypto standard for wallets?

Hello, Does anyone know how I can get my legder nanon s to work with an smart phone as huawei p9 lite ? I bought the cable kit Ledger offers for an extra €15 but nothing works, the device is total dead. If I plug it into a PC it Works just great.
