No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

I don't think of it as a selfie camera, I think of it as a camera for video calls.
For me it's a giant hole in my screen that doesn't serve any purpose.
look, if you cant figure out what to do with holes thats your problem
Instructions unclear, dick stuck in charging port
It has purpose. The billionaires use it to spy on you
It's often also used to detect if you're holding it to your ear, which allows the phone to switch off the screen when you're in a call.
@Hyperreality @stebo02 no, there are extra proximity sensors for that feature.
~~Not always. More and more phones in the budget range utilize a "virtual" proximity sensor which actually uses the camera for the same function.~~
Painting a small black dot over the front facing camera caused me issues on my previous phone, so I suspect some cameras cheap out on the proximity sensor and use the camera instead.
i thought that was just the gravity sensor (holding the phone vertically vs slightly tilted)
You're thinking of the gyroscope, but no. Some phones have a dedicated proximity sensor for things like detecting if you're in a call and have the phone up to your ear, but more and more phones (especially the budget ones) these days use a "virtual" proximity sensor which utilizes the front camera to perform the same function.
that's interesting... wouldn't that kind of sensor consume a lot of battery? turning the camera on and off every time you use it, and to determine the distance I assume it's autofocus?
