How can I change wallet's password on AndroidO3 Wallet?

Hi,
If I delete wallet from Android and reinstall using private key for NEO and seed for BTC will I be able to set a new password?
Is there an easier way?

Yes
when you import the private key or seed, you need to set a new password.
In the Android version, currently only NEO can change the password by clicking ‘Key’ and ‘Edit’
For BTC, you can ‘quit’ the wallet and then reimport it.
