orientation sensor - XPERIA X1 Q&A, Help & Troubleshooting

Hi All,
My xperia doesnot respond quick enough or doesnt response to the orientation of the phone at all(switching between the potrait and landscape view of screen).
I manually checked by putting magnet near to the phone,this time xperia quickly changes the screen mode(from potrait to landscape or viceversa).
Is there any configuration that i need to do??any sw upgrade??
Thanks & Regards

xperia dont have G-sensor, sooo dont waste time

But its responding to the magnets.How dat is possible without the gsensor??

G-sensor is affected by gravity.
Magnet sensor is affected by magnetic field.
Accelerometers are G-sensors except they are also affected by movement of the phone such as shaking, or hand gestures.
G-sensor works when the sensor detects which way the sensor is facing
Magnet sensor is like a "trap alarm" every time the sensor notices a magnetic object passing by it's "door" it will trigger the "alarm". The alarm will tell the screen to change into landscape. When the magnetic object is not present, it will trigger instructions for the screen to revert back to portrait.
Basically on your Xperia is a magnet and a sensor. The sensor is what you call the keyhole. The magnet is what you call the key. Every time these two correspond to each other, it will trigger an "unlock", and every time these two disconnect from each other, they trigger will a "lock".

"G-sensor is affected by gravity.
Magnet sensor is affected by magnetic field."
I dnt understand the difference between the two,as earth act as a magnet.
According to my understanding a magnet should align itself according the earth's magnetic filed.Incase of of xperia detection of the change in magnetic filed should trigger changing the xperia view mode. Is there anyother usecase of putting the magnetic sensor apart from changing the view mode?

And that's why magnets stick to plastic.
But really, no.
Gravity and magnetism are two different things. We don't understand gravity proplerly yet, we are able to measure it, and predict it's effects, but as of yet, we don't know what causes it.
In short. No, your phone's magnetic sensor can not detect gravity, nor can it detect motion unless there's a mgnet nearby.

No he is right
earth has a magnetic field as well ... which is very weak and is used for the compasses and digital compasses. so i guess the right answer is that the magnetic field of the earth is so weak that it doesnt intefere the magnetic trigger of xperia which is instead triggered by the opening of the slider (magnetically). well of course than Gsensor is based on gravity which is different from magnetism.

Gravity and magnetic fields are different indeed. Yes, earth does have a magnetic field, probably caused by the many metals inside the planet.
Gravity a force inherent to all mass. The bigger the mass, the bigger the pull. Earth is big --> enough gravity to pull everything on it towards it (atmosphere, animals, rocks, plants etc.). It's also what keeps the earth orbiting around the sun (sun's gravity). Had gravity not existed, the centrifugal forces would have flung us into space. We indeed don't exactly know why gravity exists - yet.
Magnetics are based on poles, electrons etc. Positive and negative - a whole different principle, with - although with a different origin - similar properties to gravity.
Though, lets face it, if people have to tell you why and how gravity differs from magnetics, I doubt you should be on this site, or on the internet in the first place.
(school would be a nice place to start, they teach this in physics)

this thread is hilarious

yes that is what actually wat i wanted to ask.I think because of the weak earth's magnetic field xperia isnt able to change the screen view.
Is there any tweak that the sensivity of xperia((towards magnetic field) can be increased?

No!
There is only to way to change screen view on X1:
1- open the hardware keyboard
2- set a hardware button to screen rotation

or magnets.

The X1 has no G-sensor or accelerometer. The reason why you're able to change screen orientation using magnets is that the magnets are in someway triggering the hardware keyboard's rotation switch.

Yes, go to the North pole and X1 will automatically go to landscape. Go to Antarctica and X1 will automatically go to portrait. Go anywhere in between and you have to use the keyboard or softkey to switch orientation.

Guys,
I smell a toke jopic.
TC, why don't you just wear a magnetic band on your wrist? Then you can wave your wrist over the phone and it'll switch its orientation.
Cheers.

water wave produced when press on the screen

HI all, I dont know if anyone has this situation...
Everytime I press on the screen, the screen generates a bit like a water wave and the situation is just like pressing on a LCD monitor.
My old M3100 doesnt have this situation...how about u guyz? do you have water wave when u press on your tytn ii?
thanks
Hmmm, maybe it's because you ARE pressing on a LCD screen... I never press hard enough to see it, but I'm sure it would.
Yea seriously, how hard are you pressing? I don't think you need to be pressing nearly as hard as you are. I can see the ripple if I press really hard, but that much force isn't necessary for your taps to be recognized (and its probably not good for the screen).
I was going to post about this earlier. I too have this problem. I owned an 8525 before, and it never rippled unless you were exerting massive force.
My current Tilt you barley tap it (like say, you are touching the dial pad to call someone) and it has two large ripples happening.
Is this normal for everyone? I called ATT about this, and they just sent me a new one. I just haven't opened the new one yet.
I found this out cos I am using my finger to use the Touchflo...I didnt apply a very aggressive pressure on it...I even see the ripple when I slide the keyboard out. Is it normal?
no its not normal if you are pressing softly and having wave like that. Please do the warranty exchange.

Hi
It depends on the LCD panel, there are different types of panel, some will ripple when pressed or distorted even very slightly others don't.
The problem with asking others is there are at least two different types of LCD panel used in the Kaiser. One we know to be transreflective that works in direct sunlight and looks kind of green rather than black when off, and one that's not transreflective that is black when off and doesn't work too well in direct sunlight. These panels may well be using different LCD technologies in other ways meaning not everyone will see the same as you.
Mine isn't transreflective and doesn't do this, so perhaps you have a transreflective type that also ripples under pressure. It isn't a fault with the LCD display, rather HTC sourcing whatever types of panel they can get at the time for the cheapest price. You wouldn't normally use a panel that ripples when pressed on a touch screen for obvious reasons, but HTC have. Maybe it was a shortage in supply and there are not many that use this type?

Phil
It shouldn't happen. Exchange it.

They sent my second one out to me at no charge. They forgot to include the shipping labels...again... so they will probably just end up letting me keep the device.
Anyhow, my Tilt ripples exactly in the same place that the video showed, and in the same way.

We don't know this at all, there apparently are at least two screen types but neither was transreflective, both blew out in direct sun.
The ripple is a function of the thickness of the glass screen. Since liquid crystal displays work by electrostatic twisting of a liquid suspension of quartz crystals thereby bending the light to allow it to pass thru polarizing filters, any physical movement of this suspension will also cause visible light artifacts. So if the front panel is lighter weight material, it will show more "ripples" if pressed firmly.

There are different technologies used in the production of LCD panels and how the glass is spaced to give room to create the pockets for the liquid crystal.
Some displays "water" when you press them, others don't, it depends on what the type of LCD display it is. My monitor at work can be pressed and nothing happens, my one at home is the opposite. It's not hard to find this explained on the internet.
The Kaiser is using different types of display using different technologies. Typically for touch screen applications (unless the display as a touch glass front) would not be of the type to ripple when pressed for the reason it will be pressed and flexed, but obviously HTC is supplying anything they can get.

Keyboard Slide Magnetic Sensor -- Where is it?

Folks,
I have an AT&T Tilt that works great except the screen will not rotate when the keyboard slides open. I'm pretty sure it's the magnetic pickup since I can wave a magnet around and nothing happens. My question is: Where is the sensor located? I would be happy to replace the sensor if I knew where it was located and/or what board/component it is a part of? Please???
Did you disable the wakeup on slide??
No I didn't. Trust me it's broke.
Please??? Someone has to know where the sensor is.

A tip for improving watch face activation...

I prefer to leave my watch face off until I look at it. The problem is that the accelerometer on this watch isn't always as sensitive as you might like (probably to prevent accidental activations). Unfortunately this means that if you have your wrist on the desk and then look at the watch, sometimes the face will not activate.
What I have found though is that if you give your wrist a slight rotational flick towards yourself as you raise your arm, the screen activates much more reliably.

You can switch the screen on by pressing the button or touching the screen but raising your arm doesn't do it.

I agree - it is neat.
I had expected mute to stop alerts and cards popping up but hadn't realised that it would stop activation as described and when I first noticed it, I thought that my watch was faulty. Posting details here in case anyone else thinks the same!

I have the exact same observations as well .. in fact, if the watch has been idle for some time,even with the slight rotational flick, I find that the screen will not be activated.
I found some custom watchfaces were *much* slower and often took two wrist-flicks to get the watch to wake up.
I found stock faces and also better 3rd party faces avoided that problem.
YMMV
Ahh .. i AM using Facer and Custom watchfaces ... perhaps the graphics are slowing down the watch ..

Two red dots?

I never noticed it before, but two tiny red dots appeared on each of the bottom corners in the capacitative button area. It looked like some kind of led, but they were very dim. I tested it and it looks like they appear when the micro-usb is partially in. Has anyone else seem them or know what they are?
I noticed them too. I thought they were sensors for the active display so when you reach for the phone it senses your movement and lights up the display. Not sure though, just a guess.

Yeah, your guess is spot on.
I do believe they are infrared sensors (hence why you can slightly see them in the dark as red-colored dots), and they are pulsing constantly to detect any reflection that would indicate an approaching hand.
You are correct, there are actually 3 of them, two on the bottom and one on the upper right corner.

Not in each corner actually. The bottom two and upper right. The 4th one is next to the proximity sensor and FFC. I saw it in a video posted on here before. Regarding the sensors that is.
Interesting.
Did not realize that feature was driven by IR sensors.
How do they tell the difference between an approaching hand, and being pressed up against your leg in your pocket?
The software is able to detect whether or not it is in your pocket based off of either the light sensor, IR sensors or possibly a combination of the two.
Sent from my XT1254 using XDA Free mobile app
Wouldn't the motion sensor come into play in determining if it's your pocket?
I believe "Pocket mode" is determined principally by the "proximity sensor" - the same sensor that determines when the phone is against your cheek during a phone call and turns the screen off. When pocket mode is enabled, the "active display" is disabled, so it doesn't display notifications when it is in your pocket. I believe the pocket mode also disables the ir sensors, so it isn't trying to determine if you are reaching for your phone.

Correct. Cover the proximity sensor and give it a try. Shake the phone and wave your other hand, it won't turn on.

OK, still, what do the 3 red lights do, if you cover the proximity sensor, yes the screen won't turn on. But, the lights still light up and wont activate. They obviously aren't there to activate the screen, so what are they?

[Q] Magnet keeps activating screen, drains battery

I found out that whenever a magnet is close to the screen (like the ones to be found in auto wake/sleep smart covers ) the screen will go off, as it should, but wakes up again after 10 seconds.
It will keep doing that forever: wake up, sleep due to inactivity, wake up, sleep, etc etc. It is obvious that the magnet is somehow triggering the screen to wake up.
You can easily reproduce this by placing a white board magnet on the device (place it between the hours and minutes of the lockscreen clock). Just wait and see what happens.
This means that you are certain to drain your battery when your phone is idle, sitting in a smart cover like the official one from Casemate.
I would love to use the smart wake, it worked flawlessly on the Nexus 5 but works only as a battery drainer on the N6
Is there anything that can be done about it? or is it a hardware issue?

The magnet sensor of the N6 is under the M logo at the back.
When there is a magnet on the M or there above on the display the screen is switched off. And stays off, but . . . a weak magnet that moves a bit away may cause the problem you described.
The magnet sensor cannot be disabled (could not find an app). The solution is to remove the magnet from the cover.
BTW this may occur also with a (belt) case that has a magnet closure. That closure must be about 1 cm from the M logo.

Thats interesting, i didnt know the sensor as at the back. When i place the magnet there, the behavior is different. It does not go on entirely, instead it goes to ambient display. But not consistently... Weird.
Anyway i purchased some cheap neodyium magnets from eBay that are supposed to be quite strong, maybe that will have the desired effect. I plan to attach them to my spigen cover.

I've observed this too. I wrote a Tasker app to sound a notification everytime the screen turned on (since my casemate flip case was closed) just to prove I wasn't crazy. mine turns on with every magnet (auto sleep) case I've tried. this is with stock software.
after posting about this issue in one of the case threads in the nexus 6 accessories forum, it turned out not everyone experienced this issue. or at least they didn't know they did.
I just wanna know how Google can even sell the casemate case in the play store when this issue exists (at least for some)...
Xposed has a module that turns off the magnetic sensor. I have no idea if it works or not so look at the thread for it. My phone is naked so I don't have this problem.

On the hard cover I mounted a small round metal plate (glue) at the same height as the M-logo at the back.
I did choose that place, because it is above the coil for wireless charging.
But. . . . the problem is that exactly there the magnet sensor is located.
So when the N6 was mounted at the neodymium magnet, the screen becomes black.
The first thing I tried is to disable the magnetic sensor with the xposed-module. Unfortunately is does not work on the N6 with Lollipop.
Xposed need to be updated.
My hardware solution is to glue the metal plate on the cover, about 1 cm below the M-logo. And then wireless charging is not possible (metal becomes hot).
I am using at the moment two ultra thin covers for the N6. One with metal for car use and another original to allow wireless charging.
Same problem with the official case mate cover, it is useless. I pulled mine from a shelf this week wondering why I wasn't using it, two days later "ahh, now I remember...". One of the many reasons I don't like this phone. Generally, Motorola does a nice job but when they don't, the phones are real duds. At least this problem is better than those with the screen protectors keeping the screen off when you make a call.
Someone mentioned a fix using gravity box for the ambient display activating in a pocket and causing phone calls and texts inadvertently; I think it was setting to keep the screen off if the proximity sensor was active, like in a pocket. It would probably work for this problem too.

When a magnet stays close enough to the M-logo there is no problem. But most leather cases are flexible. Little movings will continuously activate and deactivate the magnet sensor. So the screen is frequently tuned on.
We need a software solution that turns the magnet sensor completely off.
In the meantime you need to remove the magnet from the case/cover and replace it with Velcro.
In some types of cases the magnet is not in the center. Put the N6 in the case with the M-logo turned away from the magnet.
When the magnet is about 1 cm away from the M-logo, the magnet sensor is not activated.

The update really didn't make a difference for this but I did notice that for the official cover, either I received a defective one or the magnet is extremely weak. Velcro won't help as it doesn't have a flap to keep it closed. I guess the prosimity sensor only works with a phone call.
