I have a Galaxy S10 running Android 10, and this has happened to me several times in the past few weeks. I'll make an outgoing phone call to some business, get an auto attendant that prompts me to enter an option, e.g. 1. When I instinctively and immediately press the spot on the screen where the "1" is on my phone keypad, LastPass pops up right then, right over that area (the top left corner of my phone screen where the numbers "1" and "2" are). So I end up pressing LastPass by mistake. When pressed, LastPass prompts me, full-screen, for my fingerprint to log in to the app. Even if I quickly try to cancel it a couple of times, I just get prompted to enter my Master password to log in instead, because I haven't entered my fingerprint successfully. This ends up resulting in LastPass being in my way, full-screen, for several seconds at best. By the time I either do get my fingerprint to take, or enter my Master password, and then click off of LastPass, I've usually missed the chance to enter the option I need to have my call go to the person or department I need to speak to, and that often results in me having to hang up in frustration and call the business back. This has happened enough for me to start just using my office phone instead to make a lot of my calls, and that's super annoying to say the least.
