Some people only have one computer and that must suck. Fortunately I have multiple so I can use some of my alt-miners to do this safely.
Yes also me i have one phone, how can i do this safety?Smartphones do not have good security. If you must use them for for holding Bitcoin I would back up your entire wallet to an external drive. Then i would do a factory reset. Restore you wallet. Do not download any 3rd party software. Do not connect to public wifi.
The most reliable way is PaperWallet. delete everything in the computer and on the phone. Print as PaperWallet.
