When it comes to Android, updates. Especially for some of the cheaper phones where they don’t support updates past the next version of Android.
Which really only matters to people that actually give a shit about updates. A lot of people in Android spaces online seem absolutely flummoxed by this but many people simply do not care or actively dislike “the latest and greatest” updates. They tend to change things people liked, they increasingly break functionality in the name of “security”, and they often come with UI changes people find frustrating.
If the user is comfortable with their device, many would like it to stay that way. And that’s not an invalid feeling.
I used to anticipate Android updates, but ever since 10, I’ve had zero desire to upgrade further. I’m not buying a new phone for the benefit of having my file explorer broken.
Some people will call you stupid for this, because it leaves you vulnerable to exploits that don’t get patched, but whatever.
