Without a computer, this is probably the best he can realistically achieve.
What software is he planning to use to generate his wallet? Probably the simplest method would be to use Electrum.
I would then start by putting tape over any cameras on the phone, and doing the rest of the process is an empty room with no other electronic devices and curtains closed. Format an SD card in advance. Then, format the phone, let it boot up, connect to your WiFi, download and verify the Electrum .apk, and transfer it to the SD card and remove the SD card. Then, format the phone again. This time, as soon as possible after the phone has restarted ensure everything is turned off - WiFi, mobile data, Bluetooth, NFC, etc. Turn on airplane mode. Bonus points if he can make some kind of Faraday box to put the phone in while he is doing all this. Install Electrum from the SD card. Use it to generate a wallet, and then write down by hand the seed phrase and a couple of receiving addresses. Then create a new wallet on Electrum, enter the seed phrase from the hand written back up he just made and double check it generates the same addresses as he has written down. Format the SD card and then the phone.
Topic: Paper wallet on Android phone - page 3. (Read 572 times)
I have a friend that wants to buy bitcoin, he wants to hold it for a very long time, he has no device he can use for it and only what I can think about now is for him to go for a paper wallet and he accepted after I explained about it to him, but the problem is that he does not have a computer at all. What I think he should do is to create a paper wallet, but he does not have the device which he can use.
He has an Android phone and he is ready to format it to make the phone look like new, install a bitcoin wallet on it offline and use it to create a paper wallet. The problem is that he can not remove the bluetooth and wifi, he can just only not enable them and make the phone to be offline. Is that not enough to create a paper wallet?
After he use that to create a paper wallet, he will format the phone again.
