It rarely happens right when locking the phone, mosty because I already developed the habit to press the power button not with the tip of my thumb but lower down, where the joint is. But when shoving it back in my pocket it still happens on a regular basis, even when I try to avoid it. The button is just located in such a way that it's very hard to avoid touching it while doing so. Then I pull it out a while later to find I changed 20 settings and made a dozen in-app purchases. ;)

Can you use double tap to wake when you just need to check the screen? This will also reduce the mechanical stress on the physical unlock button.

that also never happened on any of the string of cheap chinese phones I installed lineageos on before deciding the world was sketchy enough to mean grapheneos was the minimum viable level of hardening for my phone. I miss the power button fingerprint scanner dearly.

No, one of the new "nokia" that run stock android.
