[HOWTO]Fix Stuck Compass on RAZR - Motorola Droid RAZR

Hey Guys,
First time Razr Maxx user here, after all of your input i've made the jump, thanks guys
I want to contribute a simple fix to you all, I've read that some people have their compass sensor stuck on one direction continuously, no calibration can solve it. I myself had this problem today, but it turns out it is fixable easily.
The cause:
The Phone (especially on the top right, right after the front cam part, where the sensor is located) gets too close with a magnetic object for a long period of time
The Tools needed:
Phone Tester app on Google Play Store
Small Fridge Magnet (Magnet doesn't have to be powerful, at least it will stick to fridge door or your PC case)
The steps:
Install and Open Phone Tester app, go to Sensor menu,
you'll find one of the axis is stuck at one value, mine was stuck at Axis X value at 1159.1 uT
Place the phone lying on the table, screen is upside
Place the magnet around the top right part of the phone (it is Maxx version but CMIIW on the standard one), right after the front camera part. You should see the stuck sensor axis fluctuates.
After 2-3 seconds, Remove the magnet, review the axis value again with moving around the phone.
Repeat step 4-5 until the axis value fluctuates continuously with your phone movement.
You're done
If the problem persists, please consult to the dealer, but the above fix was 100% successful for me so you should try it. Below is the attachment to describe which part should be attached with magnet for a while. Hope it helps
G'day!

Thank you, thank you very much.
It works.

In my case, most probably I got the 'stucked compass' syndrome, when I put the phone and earphones in my shirt's pocket. Since the earphones also have magnets, it may magnetized the metal in the phone's component, and affected the compass.
Actually I am almost going to send it to the Motorola service center for the repair, but, not need to. Thanks for the tip.

Nice to know it works well for you mate

Confirmed! This works. In my case it's undoubtedly caused by the magnetic lock of the pouch. You saved mi peace of mind, I was starting to think my Razr was defective. Thank you! (button pressed)

Excellent, it worked!

Thanks so much for this, I thought my compass had crapped out and now it's working perfectly.

Thanks!
Beautiful!! Easy solution that worked on both my wife's and my phones. Both were stuck and both now work. I have a geocaching app and we each have Google Sky Map, neither of which were working properly-until we used this extremely simple fix. One suggestion that I remember from my days in radio; rather than just set the magnet on the phone, move it around in circles for a few seconds as we used to do to degauze tapes for reuse.

Not certain but this didn't seem to work until I got the magnet to around the center right side of my RAZR (non Maxx) near the volume rocker. That seemed to unstick it!
:good:

Multitouch doesn't work if you don't hold the hero with both hands.

Ok, probably not. There's gotta be a perfectly valid explanation, but I just noticed this:
When I open Albums on my Hero and look at a single photograph, I can zoom in and out by pinching. Same goes for web pages. We all know this.
But the thing is: if I put my phone down on the table and try to pinch with just one hand (thumb+index finger), it doesn't work!
I only need to touch the phone with one finger on my left hand and it starts working. I have to touch the back or the frame. The chin doesn't react.
I tried it on an iPhone and it works with only one hand. It must be some conductivity issue and the Hero simply has a touch screen that works differently from iPhones.
It isn't really a problem for me: I can hold the phone in both hands while pinching. I just found it slightly interesting...
Yeah I have noticed that as well. Although if you try to calibrate using the g-sensor calibration tool it sometime fixes the issue...
Clue is in the technology? Capacitative touch screen....hit the physics books guys
A good capacitive screen doesn't require the user to complete a circuit with the phone using another hand to hold it, or by touching the bezel with a finger. The problem is either in the circuitry driving the touchscreen or possibly with the algorithms used to establish finger gestures and position.
It's even feasible that the metal bezel interferes with the electrostatic field introduced when your finger is in proximity with the screen. This would explain why the sensitivity is reduced around the edges of the screen.
Spose you need to form a complete circuit for it to work. Interesting point though, I didn't know that capacitive screens needed a second 'plate' to work (i.e. more than just the screen alone).
Makes sense though if you think about it.
Q.I indeed

The metal bezel actually acts like a ground point between the capacitive circuitry and your finger. When you are touching at the very edges of the capacitive area there simply isn't enough room to get a good grounding point so the driver/controller gets a hard time of locating what points are actually grounded. The bezel helps in this regard.

...perhaps not then lol
Yeah, well I hate to be the one to ask, but why does it work on the iPhone then? I realize it's a grounding / closed circuit issue, but if another similar phone can do it, then there's obviously a way around it.
And another question: Why doesn't pinching work, but normal one-fingered touching does?
Only place where I could see this becoming a problem is when you dock your device to some plastic holder in a car and want to pinch to zoom in some navigator software. Letting go of the steering wheel to use two hands on your phone isn't necessarily the safest thing in the world. One would assume though, that the interface in any navigator software wouldn't require complex gestures while operating it...
i confrim, using hero without touch the metal edge result in less responsivity and difficult on multitouch operation
hope new firmware can solve this, too many errors using it like a normal keyboard on a table!

How to remove "moisture under screen"

Hi all,
I had a big spot (3'') at the middle of my tab. It seems it is related to case warping and NOT related to temperature, etc. What I am describing worked for me and my tab now has a perfect screen (this is the 7th day).
I solved it by doing the following:
1) put the tab on a flat table. The screen should face upwards.
2) with two fingers push down at the top left and top right corner at the same time. You should try to "bend" the top corners towards the table. This will pull the screen away from the digitiser.
While you do this you should see the spot shrinking. If it does put some more pressure until it completely disappears. Don't put too much pressure to break anything
If, while you push, the spot doesn't shrink then stop and try the bottom left/right, perhaps your tab is bent there...
Hope it helps.
DISC:
I am describing here what worked for me... it might not work for everyone... don't blame me if it doesn't work or if it makes the situation worse.
Putting in the fridge less than 10 minutes works for me
Sending mine back to Samsung to have the LCD replaced worked for me. It's obviously a flaw in the design and the rush to get it to market without thoroughly testing it is the root of the problem.
Why on earth would you try to fix something like this yourself? You won't fix it, and its likely you will make it worse (battery damage etc)
This is why manufacturer gives you warranty, with gtab you have 2 yrs of it... I just send it few weeks without won't kill you but at least you will have fully functional device...

Mmmm Sure this helps?
I'm kinda scratching my head over all these fridge repairs for the Newton's rings problems. There shouldn't be a single 10.1 Tab anywhere on the planet that isn't in warranty. Just get it repaired/replaced.
None of the published fixes worked for mine anyway. Tried refrigerator, freezer, blowing, pushing, twisting, etc.
Verizon is replacing it. Just get it fixed right.
My biggest concern is the couple of reports of folks getting it back from Samsung and having the exact same problem reappear after 2 months. I am not sure anyone has conclusively confirmed an "improved" screen being installed during warranty service.
Could indicate the hardware is just fatally flawed for being subjected to heat >80F and any kind of pressure on the screen.
Keeping my fingers crossed that I get mine back with some sort of new and improved screen.
Works Like Charm
Tried this myself and it worked perfect!!! Thanks so much!!!

[Q] Screen turns off when i dial someone

After I updated my Nokia Lumia 920. the screen turns off when im dialing someone, and the only way to get it back is to restart it or if the person on the other end hangs up.
Could it be the light sensor? or is it just the phone update that messed it up?
http://discussions.nokia.com/t5/Nok...n-t-switch-off-Lumia-920/td-p/1606440/page/10
Thanks!
I will return it tomorrow, since im not ready to open it after 20 days of use
now its REALLY FIXED but need to open the phone (only two screws )
Symptoms:
Experience screen and touch sensor switch off during a call, Notifications (the screen stays off, like if it was in a pocket) which doesn't turn on as usual.
Try:
If during a call you press and hold the upper left corner of the glass -just between the speaker and the upper left corner- you will notice that the sensor works as expected.
I think :
Because of the layered nature of the phone internals design and the heavy use of ribbon connectors it had to be tight to connect the board with the sensor.
My Solution:
I just added a peace of sponge (W:4mm/H:5mm/L:15mm) (all weather door and window sealant) -that comes self adheasive from one side- and sticked a small peace on the board on the opposite side of the phonejack/secondary mic connectors (Pictures attached) this will add pressure on the board to be more tight tried it and working as normal.

Mine is suffering the same issue. In the Nokia forums one user recommended to "blow air" across the top of the phone where the display meets the case right above the Nokia logo. I did this and now my proximity sensor is working. It's got to be dust getting on the sensor. I'm going to take mine apart and see if I can come up with a seal for the FFC and proximity sensor.

Lg G2 gps [fix] easy 100% no risk except warranty

Hardware Fix:
Hi guys so i was tired and fed up with the long time it takes to get a lock with my G2. So at this point since my warranty period was over i was willing to try anything, so i was searching online for a solution at that time i stumbled on this youtube video:
" Réparer en 5 minutes le GPS LG g2"
http://youtu.be/UdDJqFxpRy8
So i had to share it with u guys i am writing this literally after doing the fix and i got a lock inside my room where before i couldn't.
Software fix:
There is also a software fix u can do to get a faster lock which was posted by our beloved xda community here, it really helped the device even before applying the hardware fix so try this first before doing the hardware one:
"How to Make Your GPS Lock Faster"
http://youtu.be/oU67XHD0kj4
My great appreciation to both video creators for the great help you guys have contributed. Ty again
P.s: Proceed at your own risk!

It will not work in all g2..there is some revisions of the device that is defected from factory and some hardware component needs to be replaced.
But yes this method will improve your gps to the usable level at least outside.
Works for me, side and bottom pins were already risen from factory with some plastic, so I have only put paper under top pins.
Sadly I have broken bottom part of back cover when usb conector is, but it holds for now.

Also the side and bottom pins were risen in mine too but i lifted the top and side pins and left the bottom part because i think it was a little bit difficult to lift and i was afraid i will break it. It's definetly worth trying to do. Ty for the feedback.

Compass not working with my Mi 10

Hello together,
i'm quite unhappy because my compass isn't working for a while now, it's just being really retarded. I tried to calibrate it within the google maps app a few times by swinging around my phone like an idiot and by using "Live View".
It always strays away from the true direction in a few minutes and in some apps like Kommot or Locus Map i can't even use it (its not turning to the correct direction in the apps the direction indicator is just pointing like it's nailed to the top of the phone.
Edit:
I tried out the CIT-menu too (tapping kernel-number 5 times) but can't get a stable compass direction there.
Try in Cit, you can find it pressing on "kernel version" in settings. You can test and calibrate your compass directly from engineering mode
Hello, thx for your answer, i tried that out too but i don't know how to calibrate the compass there. Most of the times i dont even get a direction indication there and when, it's very unstable.
When i go to "more tools" - the 3 dots in the top right corner of the screen - i can calibrate a few things like accelerometer, or gyro but i can't figure out how to do that for the magnetometer.
Remove it from its case, reboot and it should work. The problem is magnetic cases interfering with the compass through poor case design. You need a case with a magnetic STRAP.

Damnit...
You're completely right i've been so stupid not to notice that. I tried taking it out of the case and recalibrating the compass before but the reboot does the fix.
That's the solution for my problem so this thread can be closed.
I was in exactly the same situation a few weeks ago. It took me a while to figure it out. I was convinced the xiaomi had sent me a broke phone but then I realised if it was broke then there'd be no output at all. Stripped the case, same. Rebooted without case and it worked. Put the case back on and borked again. Bought a new case with a strap and no more problems at all.
Its a shame because the case I had was expensive at £30 for cheap plastic but it looked really nice on the phone. I reckon you had the same case from amazon..
I bought a new case just
