Then your coins can be retrieved even if you loose your phone. Furthermore, this puts the user in total control of their funds at any given time.

Electrum-grs Android implementations:

• Exchange rates for various national currencies
• Manual receiving address management (enable in settings)
• Wallet only needs to be backed up once, on initial creation.
• Wallet backup consists of simple list of 12 common words (BIP-0039).
• Empty the wallet with 1 click
• Automatic connectivity management with fast reconnects and detection of network change
• Password protect your recovery phrase
