Android's own Gmail app is a prime example of shitty use of checkboxes in Material Design (or Material You or Material 3 or whatever the hell it's called now): There's a list of emails with a checkbox for each email on the left. If you want to quickly select a bunch of emails---for instance, to label or sort them---you quickly press all the checkboxes. If you just barely miss a checkbox, you will open the email because you press the larger selectable region (which is, btw, invisible until selected---a nod toward your "prior use" statement) for one email where a checkbox happens to be fully enclosed. Now, if you are trying to label or sort some messages that have been opened and also some that are unread, you now have one extra task of going back after labeling/sorting and marking the one that you accidentally opened as unread---if you actually noticed in the first place whether it was already opened before you opened it! On my phone, Gmail checkboxes are about 3 by 3 millimeters. If I dip my finger in coffee and lightly tap the paper on my desk, it creates a circle about 5 to 6 mm in diameter. I've opened countless emails just trying to do routine sorting and labeling via checkbox. I know there are larger fingertips, smaller screens, and people with less stable coordination than mine. Google's nested, tiny checkboxes are a waste of time and a needless security flaw, as emails often contain info you'd like protected, and cameras are commonplace and usually legal, so it doesn't matter if you are quick to close the message you suddenly opened outside of your home. The alternative? Hold each message until the checkbox populates, which is noticeably slower but lowers the likelihood you accidentally open a message. I don't understand why the Gmail "open this message" region isn't a full 5+ mm right of the checkboxes (except maybe at smartwatch resolutions). They shouldn't be enclosed or nested AT ALL! Nobody reasonable is opening messages by clicking the little blank space to the left or top of the checkboxes. (...at least they weren't until they saw my statement and decided to do it from now on out of spite or curiosity.) I also don't know why Android Studio shouldn't/doesn't harass developers with "Attention! You are committing BAD DESIGN!" alert messages when they try to put small selectable elements on top of other selectable elements that perform an unrelated task.
