You using rooted phone is not really advisable, when a mobile phone have been rooted the security of the phone is no more strong, your phone is at risk of any attack, you have to be very careful with whatever you are doing with the phone because it can easily be hacked, all your funds can be accessed, whenever it comes to wallet security, always make sure you use a new device to avoid unnecessary story, the rooted phone you bought is not safe when it comes to security, so to be at a safer side is better you don't import you wallet address on the phone, or just look for money and get a new phone which I believe is the best and your mind will be at rest that your phone is safe from hack.
It's not just rooted phone that is at risk but also non-rooted phone and that is why it is not recommended or advisable to use your phone as a wallet like installing a crypto wallet that have mobile version of the wallet that can be installed on mobile phones though rooted mobile phone have much higher risk compared to non-rooted in terms of the security your phone have. I don't think newer version of Android can't be rooted since I don't see any sites that share some guide to root the phone. If you have old phone and rooted then better not use the phone like importing wallet for example and for browsing using the rooted phone won't be a problem.
