I'm looking to get a new android phone, but many seem to have fingerprint scanners, often as part of the main button.
I don't want a fingerprint scanner, because I don't want to have to worry about the possible ("I hope they've done this right") security implications (where it's stored and if the memory is secured correctly, or whether it can read my fingerprint even when I've not set it up to...). Therefore I'm wondering if there's a way to prevent my fingerprint from being scanned even when I need to use that button (so the button still needs to work!). Would a piece of insulation tape that covers the button suffice? I've seen conflicting information about it, and none from any official source; I don't know where to start looking!
I don't know if how the scanner is implemented varies by phone, which might mean I need to make the question more specific.
I am surprised that this doesn't seem to have been asked already, but I couldn't find it ("fingerprint" is used in too many contexts!), so apologies if it is a duplicate or I'm in the wrong place!
