Upon installing Koala Wallet, open it and select "Restore Wallet" on the first screen. If there is already a wallet set up, you can wipe it following the instructions here.
Read and accept the prompts, then select "Confirm".
On the next screen, enter all 24 words of your Recovery Phrase. Using the secure keyboard that is included in the app, enter the first few letters of the first word, then select the correct word suggestion that will appear above the keyboard. Repeat this for all 24 words in order and press "Restore Wallet" to confirm. It is unsafe to copy-paste Recovery Phrases, since the clipboard contents may be stolen by other apps in the system.
Set up a PIN to protect that device, then enter the PIN again to make sure you memorized it. Done! Now press the "+" button and re-enable the assets you had previously. If you restored correctly, they will load all the balances and transaction history. If you are having problems restoring, please read our troubleshooting article here.

Restoring on new devices
If you successfully restored your wallet on a new phone, for your security we recommend wiping the wallet from the old phone afterwards. Devices will continue with full access to funds for as long as the wallet is set up. It's possible to keep using the same wallet in both devices at the same time. Any transactions made in one will automatically sync to the other. Note that passwords are local and independent to each device. Setting a password on one device doesn't change it in the other.
