Does anyone know how the phone "knows" that the screen has been flipped open? Is there an extra sensor somewhere? For that matter, how does any android phone with a sliding keyboard know that it's open as opposed to just in landscape mode?
(This might sound like a dumb question to some, but I'm honestly curious.)
It's magic

I think those "legs" have some sensor in them, cause the screen is flipping and the keyboard lights are on after the smallest movement.
Im not sure, I think its the legs

Nope. Its a magnet and a magnetic sensor. The magnet is on the backside of the screen. Open the screen partially and you can stick a paper clip behind where the phone ear speaker is. I think you might be able to turn the screen on, and rotate to landscape waving a magnet at the right spot. But I'm not sure (don't have a strong enough magnet right now). On other HTC phones you can do this, to the point that cases/holsters with magnetic closures would accidentally (and annoyingly) turn the screen on.
g1 is the same way, magnet

So, i am getting this weird issues. The phone keep rotating itself (as if i slide out the keyboard. I know this because i activate the keyboard slide out sound) at close position.
It does this randomly. anyone have this issues? seem like the switch that activate the slide out keyboard have issues.
It's a magnetic switch which is responsible for the screen rotation at keyboard slide out. Check if any magnetic objects, maybe in your pocket, could cause this.
oh.. i just use an strong magnet and the rotation switch is located on the back of the screen.
This most happen when i take my phone out of the factory case. now .. even if i leave it on the table, it does that once a while.
maybe the magnet in the unit itself is not strong enough or i have a issue with the magnet switch.
Thanks for your input.

The magnet on the case may have affected the magnet in the phone. Like when you hold a nail up to a magnet, the nail becomes magnetic after removed from the magnet. Perhaps the internal magnet has become to strong, or the polarity is messed up somehow.
Magnets are a critical thing in the world. Indeed, maybe the MOST critical. There would be no electricity without magnets, and the domino effect of that alone. No magnetic storage, jeez, the list goes on forever. But wrongly placed, they can screw things up too.
Oh, and wearing them on your wrist for health benefits in in the domain of voodoo. They do nothing for you in that area
I was having issues with the magnet in my phone case actually turning on the screen, and taking off the keylock! Pretty crazy, but it was happening. In order to fix this I had to disable the phone from waking up when the keyboard is slid out...not a big deal, I never slid the keyboard out unless the screen was on anyway. The problem is solved.
My question is will this have any negative effect on the phone? Will the magnet in the case mess with the accelerometer or g-sensor? I would hate for the case to cause future issues.
Thanks.
Anybody have any ideas?
I don't know about the accelerometer, but in my phone it seems to mess with the stylus sensor, and turn the phone on and unlock it.
The stylus sensor on the TP2 is not magnetic, but the keyboard slide sensor is. That is why magnets turn the phone on.

Not on mine - I have the universal one and that one has no magnetic unlock mechanism.
As far as I know the G-sensor has nothing to do with magnets and cannot be interfered by magnets. (Have a magnetic button on my shield)
Anytime I turn on the phone after taking it out of the case it thinks it's in lanscape mode. I had to turn off the option of having the phone turn on when the keyboard is slid out.
What I'm wondering is if the magnet in my case will effect this sensor or anything else in the phone?
Thanks.
In short the answer is no. It is in landscape mode because you take the phone out past the magnets to get it out of the holder. There is a magnet in the keyboard sliding mechanism that is used to trigger landscape mode when you slide it out. When you pull it out of the holder the phone thinks you have opened keyboard and goes into landscape mode. In a few seconds when it realizes that you havent opened the keyboard, it goes back to regular mode.
Hope this helps clarify things. Bottom line is that the holder will not do anything negative to phone or degrade its performance in any way. I have two factory HTC cases that both have magnets in them from my Kaisers. Even HTC wouldnt ship somthing that was bad for the phone with them.

Sounds good, thanks for the explanation. I knew it was the magnet playing w/ the KB sensor, but I just wasn't sure if it would have any negative effect on the phone itself. It looks as though it will not!
Thanks.
What's the best way to stop the phone answering calls when I open my case (it has a magnetic catch)? I went to add SlideWakeup = 0 in the registry, but it's already there.
I'm running S2U2, latest version if that makes a difference.
Thanks
I run s2u2 also, no issues when I pull it out...other than the screen is on, which is no big deal, but the screen is still locked.
I ran into this issue at work today. On our Vostro 3550 laptops, if the Incredible touches the right front side of the laptop right below its camera lens, the computer hibernates and won't wake up. I saw one other person ask this same question but no one replied, does anyone have any information?
That same phone doesn't do it to any other laptop that I've tried, and my Droid X2 doesn't shut the laptop in question off. Neither does an iPhone or Original Droid.
i have never heard of this. anyway you can shoot a video when it does it. that would be interesting to see.
He's a little tired of it happening today, but maybe I can take a video of it tomorrow
Well now that is strange. Does it still do this if you turn off things like wifi and bluetooth?
Wonder if it uses magnets to sense a lid close action and the Inc throws it off. If you go into the power options and change the lid close action to do nothing. It may not happen.
The speaker in the Inc is quite magnetic. I periodically have to take a little magnet to my speaker to pull off all the metal shavings that attach to it.

Good idea, it's one of those that doesn't have the latch so maybe that's what's doing it.
As for wifi and BT, both are turned off on the laptop and the phone itself. That was the first thing I looked into.

Just replaced the flex cable on my Desire and found this small rubber part on the desk afterwards. Anyone know where it should fit, I can't see anywhere obvious!

Upps
I've never seen it before!
That might be the small plastic/rubber shield that separates the proximity sensor's emitter/receiver (as depicted in this picture). Without it, the proximity sensor might function incorrectly.

God save the Queen!
Further to the image above, that proximity sensor rubber is shown at 5:00 in this video:

Thanks for the responses - proximity sensor sounds like the culprit to me, particularly as I've had a few problems with it not working lately! Time to take my phone to bits again I think, thanks for your assistance
Looks like the piece that goes on the inside of the back cover which sits over the speaker? Could be wrong though...
Hi I know exactly what it is I had the same problem I did a massive fix on my desire a few months back.
It's the Mic or the rubber bit that protects it and helps the sound travel to the Mic look at the bottom of your phone. There are 2 boards I think the top and the bottom top having camera etc and the bottom having the processer sim.card etc. When you took those out it must have fell out if I remember correctly its just 2 bumps at the bottom next to the micro USB port on the right
Hope this helps

Thanks for your replies, it wad indeed the proximity sensor piece as suggested. The video and picture above were spot on, my phone is fully operational again

Does anyone know what the sensor switch is near the bottom of the Google pixel phone/near the charging point which when activated by a magnet turns the phone off?
It doesn't seem to be the normal magnet sensor which is actually located behind the finger print sensor on the Google pixel xl
I never noticed that. have you tested it? I'd have to find a magnet to check it out.

Yeh I have a magnetic mount in the car for my phone.
And when I hold the magnet next to the finger print sensor where the magnetic sensor is, the screen doesn't turn off and the magnetic field strength is over like 5000.
When I put the magnet at the bottom of my phone, say near the speaker or behind the G logo on back of the phone, the magnetic field strength is no more than 130 but the screen turns off by whatever switch at the bottom behind the G logo that is detecting the magnet.
Really wanna find out what sensor is picking this up.

I also have a magnet mount in my car. I haven't encountered this. I'll have to test it out later to see if it happens to me as well. I'll let you know.

Oh that's odd. If you can't reproduce what is happening with me and il make a video on my old phone to show you what's happening with mine. I assume yours is a pixel xl too?
This has been mentioned before and is reproducible. HTC puts that sensor on some of their phones, it used for smart cases and such. Use a small magnet in the area of the home button and it will always sleep.

Yeh that's exactly what I'm talking about, but I'm trying to find out what it's called.
I use an app called automate, and I'm wanting to utilise this sensor in automate, and if it can utilise it in the current version I wanna let them know what this sensor is so they can look at adding it it.
just throwing it out there, not sure what good it will do, but i exclusively use magic mounts (ridiculously strong magnet, and i would reccomend and of there products to anybody). Anyways, it never fails, when i attach my device to the magic mount, the device wakes up. Ambient display and all Gestures stay off, so its not the feature that does this. its kinda weird, and i use to be worried about the magnet messing with my device, but i just ignore it.
Bosch Sensortec BMI160 low power IMU according to iFixiit, this chip is on the motherboard. I believe it can be hooked up to detect magnets for wake states (if I read the data sheet correctly, I am not an engineer). So, that's probably the name of the sensor.

I see that on their site but don't believe this is the one causing the sleep in my previous descriptions in this post as it is near the G logo /towards the power socket on the phone, not at the top where the motherboard is
I just wonder if the chip is controlling the sensor, the daughter board is pretty sparse.

Guess no one else has any idea on this then
I have the same issue, magnetic car mount, I turn the phone on, in portrait mode, I open a YouTube video, and when I turn the phone in landscape mode the screen turns off. Without the magnet, the phone acts normal.
Strange.
