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?.
You can unroot the phone you bought, then do a factory reset of the device and then install the antivirus application and install wallet applications from its official sites or from Google Play Make sure that they are official applications and not fake applications and you should not download any cracked applications on your new phone from unknown sites and sources, And always activate two-factor authentication for any exchange application or any of the personal accounts through the Google Authenticator application.
