I lost my phone days ago and now I got a used phone, the problem is this phone is rooted, I hope this doesn't carry any danger to crypto related security? Either wallets or stuff? I am careful not to import my recovery seed on the phone first, not before having a answer, I've also reformatted the phone through recovery mode but root is still present. Any Danger?.
It’s not dangerous if you knew what you are doing especially on installing mod software because that’s what rooted software main purpose. It bypasses the system restrictions which means you can do anything to your mobile phone software including installation of malicious software that can steal your credentials. Much better if you will not login your wallet on that phone if you are not sure on what software previously installed there.
