How to fix magnetometer/compass in S4? - Galaxy S 4 Q&A, Help & Troubleshooting

Hello!
I've got identical problem as in this topic for this other phone http://forum.xda-developers.com/showthread.php?t=1204845. I guess S4 has a different sensor's vendor, so my question is what file should be deleted?
At present, I'm not in possession of S4, so I anyone would be so kind and check it on their rooted device that would be nice.
1. Doest it still work when the phone is:
- touched with a little magnet like in a standard vertical flip-case (with little magnet) or
- travelling by car/bus/train or
- plugged in headphones
In the one I had (I don't have it any more) while plugging in headphones, or travelling by car/bus/train, or putting it in an flip-case with a little magnet the arrow In Google Maps pointing the direction which a device is currently facing simply freezes. Compass app also freezes at the same time. The app called Android Sensor Box in the scale for magnetometer reaches its maximum level. While moving the little magnet, from mentioned before filp-case, around a phone the arrow travels with it. Move it away and it freezes. It simply won't move. While sticking S4 to the metal part of laptop table the arrow immediately points opposite direction. Only making 8s in the air helps but only for a bit. Neither S3 9305 nor S5 have this problem. Even when stuck with a magnet their arrows in GM works just fine.
2. Does deleting the file fixes the GM's arrow issue also permanently even when a phone is in the flip-case with a little magnet?

Any hardware experts here??

Hi,
I am still trying to resolve an on going screen problem.:-((
When I have my Universal opened up on my desk the volume and phone dialogs and occasionally the anolog/digital clock dialog keep on appearing and disappearing.
Some times it hardly happens at all and other times it is contant, to the point that the touchscreen won't respond to other input.
When in PDA mode I get a similar situation from the same edge of the screen, but this time the scroll bars go mad.
Previous posts here have suggested either grit in the edge of the screen or dirty contacts. I have pulled the screen apart and cleaned all the contacts as well as cleaned the edge of the screen and the case around the 'affected' area.
Since the problem seems to be down to one particular area of the screen - is it more likely to be pressure from the case or a connection issue.
I'm inclined to think it is pressure from the case, but don't know much about how the touch screen matrix works.
Any help with this would be appreciated - at the moment the screen problems are rending the device pretty unusable.
Surely someone here mush have some ideas, this is driving me mad.
Currently running with the back of the screen off and prodding and pocking at connections to see if it makes any difference, but doesn't seem to.
Next stop is to strip down the base to see if there are any issues with the connection of the screen cable on the main board.
The frustrating thing is that the problem seem to appear and disappear - sometimes it if fine and then other times the dialogs are appearing.
When I have the dialogs appearing I try opening and flipping the phone back and forth and sometimes it goes back to normal but more often than not it doesn't.
The first thing that I want to establish is what is likely to be causing the icon area screen to appear as though it is being pressed?
Cheers,
Julian
I'm definitely no hardware expert but my Universal showed a similar behaviour a few days ago and I'm quite sure it has something to do with the case and/or the cable(s) between the screen part and the main body of the device.
In my case, only a small part of the touchscreen (lower left corner) remains working and the speaker on the display side also refused to work anymore. I've applied some pressure on the edges of the display and the speaker "slowly" began to work again... and so the touchscreen did.
Good luck :?

Is your phone now working properly?
I have had the screen apart, but do major change. Next stop strip the whole thing down.
I'm starting to suspect the cable, but cannot see any obvious problem with it.
Yes, currently my phone works perfectly.
Did you check the connectors "inside" the display part of the phone (e.g. receiver, ...)?

Hi,
I have opened up the back of the screen and checked the connections of the ribon cable to either side of the screen and also checked the connection of the actual screen to the circuit board.
It would be useful to know a bit more about how the touch screen side of things work bearing in mind that only one corner of the touch screen is being affected.
I'm going to try to strip down the whole phone and check the connections on both ends of the cable between the screen and the main unit to see if that makes any difference.
Well, I have stripped down the phone and cleaned the connections on both ends of the cable between the screen and the main board and at first for a day or so the problem appeared to have gone away, but now it is back.
I am starting to suspect that it is a problem with the actual cable, possibly a loose connection in the wires - the connectors appear OK and problem appears and disappears when the screen is flipped.
I read here that you cannot buy the cables seperately - is this true?
The next option is to take the cable out and either check all the connections and repair it, however it is a random fault so difficult the trace.
The other option I have considered is to bind the cable tightly with PTFE pumbers tape which is thin enough not to cause any problems, the PTFE will bit will help when flipping the screen and binding it might (hopefully) ensure any loose connections don't remain loose.
Any other ideas from here?

Keypad + screen issues (after reassembling)

I took apart my tytn, including the screen part.
After reassembling it, I've had random issues related to the keypad and screen.
By keypad, I mean all the keys on the screen part of the phone (D-pad, call/hangup,soft left/right, Internet Explorer & Email).
They will randomly cease working and randomly restart working (usually after turn on/off the screen with the power button)
The screen will also randomly turn white and come back on only if I turn off the screen and then back on.
Im thinking it has to do with a loose connection somewhere in the screen section of the phone, however, Ive taken it apart 2 more times to check everything out and the problem persists.
I wonder if anyone experienced the same thing and found which specific internal is the issue.
i would like to know too cause my buttons just stopped working. so the talk, end, message, Internet explorer, ect. but the left down up right and center button work.
I have the exact same issue.
All the keys (not keybord keys) randomly stops working. I am so used to it now, that I dont even try to answer the phone with the green key button.
The screen fades to white, sometimes (maybe 1-3 times a day).
The screen is white when awakening from "sleep mode", turning on and off the screen fixes that after a while (50% of the time white screen when from sleep mode).
I have found out that putting a finger nail between the keyboard and the screen, on the right hand side, when in closed position, and then putting the screen back on, gives me a 99% chance of funktional display.
The problem also accurs in the "full keyboard position", But putting the finger nail in the same spot helps.
So I think the problem of the connection is in the keyboard part of the phone, since those slide contact always are on the right hand side, and the display contact shift side.
I would lite to know if any body have a permanent solution for this.
(I have now opend my phone yet, and I have tryed the putting thin plastic between the display and the cover, with minimal success)
thanks for your time

These are the exact symptoms of the "SCREEN FADING INTO WHITE" problem. See this thread for more info: http://forum.xda-developers.com/showthread.php?t=303872
The common causes for this are a bad connection to the D-PAD controller PCB (in the technical manual they mention it should be carefully checked and the really small screews with same torque making a 90 degree with the PCB), a bad controller (that was my case, had to order a new one) or not enough pressure on the square black chip on controller (some people seem to have fixed it by putting a plastic sheet in between the chip and the case, to apply constant pressure).
I suggest you try to re-open your phone and reconnect the D-PAD PCB as carefully as you can, double checking the connection and the screws there.
I did fix my problem, by ordering a new PCB and replacing the old (probably bad) one. It started to happen after I dropped my phone and it's the only thing that worked. Now my phone is as good as new.
Hope this helps!
Similar Issues with screen
I have similar issues;
Anything thats on the foreground gets closed by the 'x' button and if I slide it open the start button gets continually pressed!
Seems to be the top right corner of my TS thats at fault
sometimes it's fine....most of the time its not!
Andy.
I have the same! I have a huge dead spot in the middle of my (Tytn) screen, and if you tap there it actually activates the "ok" in the top right corner. The rest of the screen works ok. Whilst drawing in notes any drawing near the center dead spot results in a streak to the top right hand corner...
Bad screen?
Bad rom?
Bad motherboard?

You can rule out the ROM and M/board in my view for this specific problem. Your issue is very similar (and I think has the same cause) as those who find programs close randomly when in portrait mode and when they open the keyboard the start menu often pops up untapped.
I think this is just a case of a bit of pressure being put on the screen top right corner. Some folks have tried the business card run around under the bezel fix and had some success others have had to return for replacement/repair.
Some have taken the device apart and removed the gasket around the screen under the bezel, but this is not guaranteed to work.
Others have replaced the screen and for this particular problem it is very rarely successful as the screen is not normally damaged.
If you have a warranty use it - all of the above "fixes" are warranty voiding.

Hi Mike
It's an interesting problem as when performing a click and drag in Notes (drawing mode) the center section of the screen seems to work normally - a square box can select an area right through the middle of the screen - suggesting that the screen (as you say) is OK. So what is causing the a tap in the middle of the screen to register in the top right hand corner, when we now know that the center of the screen can work and respond in the correct manner. The size of the affected area is about the size of a thumb print EXACTLY in the middle. Personally I would like to believe that performing screen alignment 4 - 5 times a day for the past year has worn out the center dot and that is affecting the surrounding area. The trouble is that this fault has been reported on this site a few times now, and everyone says it's caused by something else! What did I do immediately before this happen I hear you ask? I flashed a new radio rom and was fiddling with a piece of card I have wedged down the RHS side of the screen to try and help stabilise the screen alignment. Since this problem arouse, I have removed the gasket - but that hasn't fixed it. I'm going to try and boot up the phone out of the casing to see what "zero" pressure applied to the screen does.
I'll report back...

It will be interesting to see what results you get. You'll need the old rubber band technique to hold the battery in place while you do it!

Well it's not due to the case squishing the sides of the screen as I just dismantled my hermes, wired it all up in bits on my desk, powered it up and still the screen has a dead spot in the middle and phantom taps in the top right. Temperature is normal room temp, approx 22deg c today.
I'm not sure the exact mechanisms of how these touch screens work out where you are tapping (resistance, voltage), but it looks like there are 3 separate strips running around the screen. 1 goes straight across the bottom, two goes up the LHS and across the top and 3 goes up the RHS. Therefore there is a gap between strips 2 and 3 in the top RH corner. Coincidence? hmmm It seems to me for it to register a tap in the top RH corner, strips 2 and 3 would register low voltages (or high resistance) and bottom wouldn't register at all. Thus suggesting a fault with the PSU that powers the touchscreen. Taps near the edges work because they are near the edges and therefore the resistance is not too great and can be detected, taps in the middle and worse off because they are far from all the detecting edge strips.
Does anyone think that there might a registry tweak for boasting power to the touchscreen?
Hermes Whie Screen Problem
To fix the "white screen" problem, you have to take your unit apart, and reconnect the ribbon cable.
I have a new 8525 and it started happeneing to me, so I took it apart this week, and reseated the ribbon connector.
Fixed the problem.
Has anyone here read and understood all that is said here:
http://msdn2.microsoft.com/en-US/library/aa919680.aspx
Perhaps someone could compare the touch.dll in Black Majik to WM5 - should be the same right?
How come that HKLM/hardware/devicemap/touch doesn't show the touch.dll driver as drivername? Keyboard has it's driver...microsoft says it should say drivername = touch.dll
Do you all have that in your registry?

Unresponsive screen when in car dock?

Basically, the phone screen is unresponsive when your not holding it or any time it's not grounded. If I put it in the car holder and then touch the screen, its very sporadic. I have compared it with the droid eris and the Moto Droid under the same conditions at the same time, and it performs flawlessly. I have tried the incredible with the screen protector and without. If I take it out of the dock and hold the phone in my hand, it works great again. It's not just the car dock either. If I set it on certain surfaces and just touch it with one finger it does the same thing.
The car dock itself has nothing to do with it. I've narrowed it down to a grounding issue. I've also tested 3 Incredibles and ALL of them do it. I am going to post another video showing it on top of a piece of styrofoam which also creates the problem. It's definitely more widespread then just a few phones. Basically, If the phone has very little ground it is unresponsive. If you ground it, either by holding it or placing it on a surface that is grounded then it solves the problem. If you plug anything into it that is grounded it solves the problem.
Here is a new video on different surfaces. It's not a car dock issue. If it is some static issue as some are saying, it works great on a eris, or a moto droid so it's not capacitive screen in general.

My goal for this thread, (now that I see it is happening to a lot of phones) is too get enough info out there so that other people can effectively recreate this problem on their phones. With enough people, I am hoping HTC or Verizon can offer a fix not just a work around.
UPDATE 5-17-10
I received 2 replacement Incredibles from Verizon. Both phones respond in the same way as the original. I called verizon, and they said "they are compiling a list of problems to send to HTC and they will add this one to the list". Hopefully the rep that I spoke with wasn't just trying to shut me up. I don't know... Anyway, Here is the last video I am going to do on the topic. In this I wanted to clearly show the following:
- It is not a "Capacitive" screen issue in general (MOTO Droid, and Eris are fine)
- It is a MASS DEFECT of this phone. (I am not saying ALL phones)
I am going to forward this message and the video to HTC. I will post the response. Here is the link to the new video.

not the same as yours but i have a similar issue. i ordered a few usb wall plugs from monoprice. whenever i use one of the usb wall plugs to charge, the touch screen is unresponsive. The volume rocker and power buttons, but the screen and bottom row of buttons dont work. Using the factory usb wall plugs everything works fine.

I have searched for someone having this problem and haven't found anything yet. So I apologize if I missed it somewhere. It's one of those problems that is difficult to recreate ALL the time so that's not making it any easier.

My wife has the incredible also, and it's doing the same thing in her car. Did we just get a bad batch of phones? Is this screen just crappy under those conditions? It would make this a totally useless phone if i can't use it in the car.

I've never had a capacitive touchscreen phone, so I don't know for sure; but maybe it has something to do with the relative capacitance. When you have one hand on the back and then touch the screen, maybe it senses a greater variance in the capacitance. If it's on the table or in your car cradle, maybe the variance in capacitance isn't great enough to register a touch. I'm not familiar with Android either, but maybe you can adjust the sensitivity? Just like those touch lamps, capacitive sensors are triggered by a relative change in capacitance and if it's not greater than the preset threshold, it doesn't register that you touched it.
Just an idea... again, I'm not really sure. I'm only lurking around in these forums because I have an Incredible on order. I'm just throwing some odd ideas out there. Good luck!
It is the type of charger/how you are using it! I had this issue. I could plug in via the provided charger and it would work. But I went on a trip and hadn't purchased a car charger yet so I grabbed my laptop ac/dc converter and plugged in the provided charger through it and my phone became unresponsive. If I plug it in the wall presto it works. The new car charger works as well!
I am sure it has something to do with the voltage being released through the charger.
Here are a couple of video's I did on the topic.
http://www.youtube.com/watch?v=bsKc1_wG0zg
http://www.youtube.com/watch?v=pXB1MjYM5Ks
Me too
I'm also having the same issue and I am using the Verizon OEM Holster Mount Combo (Perfect fit for Incredible, no power).
I'll post over at PPCGeeks, and AndroidForums to see if we can find a fix.

You have to use original charger ... it has voltage regulator and earth pin on the other end ... static should not travel on the screen otherwise it will do the same ..
Workarounds
I did find out that it is pretty easy to do the following:
1. Plug in either the charger or headphone jack. Either of those seems to ground it out enough... I also tried just clipping the headphone jack (metal part) into the clip part of the belt clip, and that worked, so there just needs to be SOMETHING else attached to the phone or mount that gives it more of a ground.
2. Just hold the sides (or just one side) with your thumb and ring finger while navigating with your index finger. That seems to do the trick.
Hope it helps.

I'm not seeing this issue, but this can't be the real dock for the incr... which one are you using?
Capacitive screens become less responsive in the cold.... if it's in front of an A/C vent with it blaring, that could be the root cause.

Updated the 1st post with a new video.
Same issues plus some new ones
I seem to have the same issues that were reported in the youtube videos because I have a similar car dock. I am also having the same issues as hoop762 as I also purchased the wall charger from monoprice. When I have it plugged in the touch screen does not work, the OEM charger works perfect. I also purchased the car charger from monoprice but that does not cause the same issues.
I have had another similar issue when I have it plugged into my car stereo via the audio jack and a male to male 3.5 cable. When it is plugged in and I try to listen to music withe the stock audio player it starts fast forwarding and skipping songs. If I pause the music then start it again it sometimes plays for a while but will then act a fool again. I had the same issue using pandora when it skipped songs until it I ran out of skips but i have not seen the issue in other programs. I have had this issue in and out of the car dock. I will add a video later if I can.
I replied to one of your videos (as tjowatonna)
"I have never noticed this issue on my Incredible and I just tested on a variety of surfaces using the Etherial Dialpad app (it's neat, check it out if you're a music nerd) to test and had no issues regardless of if it was placed on glass, plastic, cardboard, pillows. I didn't have any styrofoam to test."
Have you had anyone else try these tests on your phone? I'm just wondering if it's not something about your body that it doesn't like as much or that it likes more for people like me that can't reproduce this.
Again, there is no car dock specifically for the DI yet.
It looks like the edges of that generic dock have a big foamy area that might be very close to the screen.
It also looks like the phone/dock is touching the dash in the video.
I put mine on an anti-static bag on my workstation and tried to only use a finger. Everything worked just fine. I know you said you tried other areas with the same result. Do you have a screen protector on?
I'm just scratching my head here.
I can confirm this issue on my Incredible as well. For what it's worth, I have a Zagg shield on the screen, and I did *not* peel it off for testing.
In *any* situation where the phone is completely isolated from ground it seems to happen. I can reproduce the symptoms by setting the phone on a huge variety of surfaces or by placing it in my (plastic) car mount, and then trying to use it with just a single finger.
As has already been posted, touching the phone body even lightly with an additional finger while it is in this state (even one from same hand) will allow full responsiveness, as will any other sort of ground such as many cable connections. Also, the silicone case from Verizon can be installed or removed, and there is no difference either way.
I also just booted my old Hero (also has Zagg shield) to check its behavior and was unable to reproduce this, even with it sitting on a double folded rubber mat on top of a big pillow. It is 100% reproducible on my Incredible though.
So be it.
EDIT: In addition to the role that grounding clearly plays, static might be a factor too (as others have mentioned).
I tried my hardest to reproduce this affect and i was unable to. I have a new zagg screen protector i have not yet put on. I will add it and re-test again and post my results
** Update
I added on the Zagg Screen Protector and tested it again. I lost some responsiveness in general nothing still like has been demonstrated.

Thanks for testing your phone and also trying it against another capacitive screen phone.
I talked to Verizon and they are sending 2 new Incredibles as both my phone and my wife's phone have the problem. I will report my results on tuesday...

Now that I have my Incredible, I have the same issues. Fortunately, I don't use it in a car-dock very often but I do plan on occasionally using it that way. If Verizon or HTC doesn't come out with a fix, I may just see if I could find a soft rubber-like material that also conducts electricity to make a grounding pad with a wire connected to the vehicle's ground on the cradle/dock so the phone's back can make contact when docked.
Update in first post...
I ordered my device on launch day, and this thing has had none of the issues you have shown, I even put it on styrofoam just to try it all out, works flawlessly.
sorry for your bad luck.

Magnetic mount affecting phone

I have two magnetic mounts and a metal plate stuck on the back of a third party case. The one in the car does not appear to cause any issues but then I don't generally touch it while on the mount. I have a cheap magnetic mount next to my computer monitor I rest it on during charging. Sometimes the buttons becomes unresponsive although I can scroll etc (I am using Nova Launcher BTW). If I lift the phone off the mount the buttons work again and if I put it back on the mount the buttons continue to work. It seems fairly random. I thought magnets should not interfere too much with smartphones other than perhaps the compass.
It's a bit baffling.
EDIT: After further experimentation it would appear the X Force/Turbo 2 is susceptible strong magnetic fields. If the phone is placed too close to a strong magnet in a certain position then the bottom half of the display becomes unresponsive. I can reproduce it every time. If I place it slightly off center on the phone the magnet does not affect it. Has anyone else experienced this issue using a magnetic car holder?
EDIT 2: I seem to have made a workaround. It seems the plate that comes with my more expensive magnetic phone holder in the car is a bit more affected by the cheaper holder I am now using indoors. I put the plate for the cheaper model in between temporarily and the problem almost went away. So I have put that inside the phone cover as a barrier and now don't get the issue as much. There seems to be some variance in the magnetic properties on each of the holders/plates which does or does not affect the phone.
Very peculiar.
The phone uses magnetic force to function with the use of Motorola's flip cover case. I have one, what you describe is almost like what happens when the cover is closed.
I had a magnetic mount that was too strong cause the motion sensor to "stick" on a different phone. Once I figured out what was causing the problem (because it wasn't obvious to me right away on that phone), I returned the magnetic mount / case and got a refund. On my other phone, I'd have to remove the magnetic case AND reboot the phone for the motion sensor to start working again. It took me quite a while to figure it out, but now I'll stay away from magnetic mounts as much as I wish they would work. It's not worth the damage it can cause to a couple sensitive components in these phones.

Problem: Video slowly moves to the right in 360ºV or cardboard apps.

Hi. I recently acquired some cardboard like glasses (blitzwolf) and wanted to give them a try. I really liked the experience, considering they're much cheaper than Oculus, and there's a nice offer of videos and apps already.
But after a few minutes I realized about a problem. You can move the video to the left or right just rotating your head. Mine moves slightly to the right or the left, depending on my phone's position (horizontal with the speakers on the left and home button on the right, or vice versa.) I guess the solution is to configure my phone's sensors, but I don't know how.
I recorded a of it, to make things clearer. I'm not moving my phone, so the entrance to the cave should always be up front, but you can see it rotates to the right.
I know this is my phone's problem, and not the device, but I consider this section to be the most appropriate to post it.
Appreciate it

Hi. I recently acquired some cardboard like glasses (blitzwolf) and wanted to give them a try. I really liked the experience, considering they're much cheaper than Oculus, and there's a nice offer of videos and apps already.
But after a few minutes I realized about a problem. You can move the video to the left or right just rotating your head. Mine moves slightly to the right or the left, depending on my phone's position (horizontal with the speakers on the left and home button on the right, or vice versa.) I guess the solution is to configure my phone's sensors, but I don't know how.
I recorded a of it, to make things clearer. I'm not moving my phone, so the entrance to the cave should always be up front, but you can see it rotates to the right.
I know this is my phone's problem, and not the device, but I consider this section to be the most appropriate to post it.
Appreciate it

I'm also having this problem in all VR apps, you can try GPS Status & Toolbox from PlayStore to calibrate your sensors, it works for many people.
For me it seems, nothing works. All my sensors are working properly, i tested them and have no erratic readings whatsoever, compass works well too, but in Cardboard... major sensor drift. The only thing i can do for now is watching 3D movies in VR Theater with the screen locked in center.
That's a classic VR problem for mobile devices. You could try an xposed module named, 'Gyroscope Noise Filter'. On my device there wasn't much drift, so couldn't notice any large differences, but you can give it a shot.
When it occurs, I try to stabilize my phone on a table for 10 secs and it stops, also it happened when I mess with dpi... My sensors should be good though, it have better range that a friend's phone. I guees it's a more serious issue for you.
Hey, Folks!
I had the same problem with every vr app on my G2 and I solved it!
The problem is the damn button "bulge" (0,2mm) on the backside. The phone never ever laid flat so theres was no way to calibrate the gyro correctly.
So I placed it on a 0,5 mm creditcard so the button doesn't touch the ground and calibrated the damn thing. BINGO! No movment.
I think this is adaptable to every phone. Think of the "flatness" of your phones backside. If theres a button or camera bulging out, the picture will move (probably) to the right.
Please excuse my bad english.
On an s5, dial *#0*#, then tap sensors, then gyroscope self test. Cured it for me.
The same

ve solved the problem. You're using an VR application like a video, for example, what you're running and hitting the phone in the other hand or something soft on all corners. As you rotate it constantly.

This also worked for my Samsung S7 stock. Looks like the "test" is actually a calibration/reset, not just a test.
