Or better yet use GrapheneOS 2FA biometric + PIN + duress PIN + auto reboot:

• If someone spies on you unlocking your phone, they don't get your encryption password
• If they figure out your PIN, they can't unlock your phone without you physically being there, and your phone may reboot to the password unlock before they get it to you
• If they compel you to use biometrics, they can't legally compel you to give them your PIN
• If they decide to start trying out common PINs and you set your duress PIN to one of them, then it wipes your phone

I don’t know what it is on android, but five quick presses of the primary button on iOS will put the phone into a mode where you must enter your password to unlock it.

Why? Apple and Google will just unlock it for them later.

Just also stop saving critical stuff on your phone you’ll never use nor open again. A good mailbox is an empty mailbox, empty signal chat and so on. With AI it is leaking any away possibly out your phone

For my apps, I use biometric unlocks. To get in passed the lock screen to get onto my phone's home screen, I have to enter a pattern. I figure that if they're already passed the pattern, more pattern won't stop any unauthorized user. So, it really isn't worth the inconvenience to enter the pattern for all my apps (like banking, cc, investments, etc.) over and over. But, if they can't figure out my pattern after so many tries, my phone auto-erases.

Or just use lockdown mode.

Jokes on the cops, my finger barely works half the time and I have to end up doing my doodle.

i guess another way is to use those shitty privacy screen protectors that do not work with fingerprints at all. They can try all they want, its not gonna work.
