H918 Compass Problems - LG V20 Questions & Answers

I am relatively new to this device, coming from Samsung. So different hardware, newer Android. Trying to work through everything. The phone is rooted and I have been making some mods including Xposed.
My latest problem is that the compass seems to be stuck pointing North (at least on some apps). This affects GPS Status and HereWeGo, both of which I have used for years now without problems. Interestingly, this does not seem to affect GPS Test app which I have also used for years.
I have seen a few posting elsewhere mentioning this same problem. Those were for Verizon models, if I recall. But even those posting said it happened before rooting, etc.
Anyone have any suggestions? Thanks!

Try this?:
Another method I've used is to lay the phone on a flat surface face up and rotate it slowly 3-5 times clockwise and counterclockwise. Then do the same with it face down (on a cloth to avoid scratching).
I've only had to do this when I noticed my magnetic sensor picking up a false reading (I use a sensor reading to launch a Tasker profile when it reaches a certain level).
Good luck.

Sorry, should have mentioned that I did all the calibration stuff. It is as if the nav apps do not see there is a compass available. On my old phone, for example, Here Navigation shows a compass icon. On the LG V20 it does not. Cheers

I know this sounds stupidly simple and you have prolly already done it but there seems to be a bug in my H918 where sometimes my phone doesn't detect certain sensors like proximity and accelerometer hence no compass and screen won't turn off during a call also can't use phone in landscape since it can't detect when phone is sideways but basically the only solution I've found is to just reboot phone and it solves it. It does it very rarely but figured I'd suggest it just in case.
Also can't remember if you said in OP but does this happen without Xposed? Xposed had quite a few bugs still and it's suggested to remove entirely when troubleshooting issues.

Hi and thanks. I am not sure of other sensors but if true, that makes things even worse. I do notice, however, that after several reboots, the compass is back and working again. Obviously, rebooting is NOT a solution for most folks. I am in the process of removing xposed to see if that has any impact. Cheers!

When it happens test to see if you can rotate your phone into landscape mode. Mine rarely happens for me and it only happens upon rebooting. It won't just happen while the phone is on

How To: Froyo Compass fix

Credit to: abrognlie for pointing this out here: http://forum.xda-developers.com/showpost.php?p=11552644&postcount=163
Figured this would be easier to find in searchs.
Problem: Your compass is backwards and overly erractic and inaccurate.
Solution: Upside down horizontal calibration
How: Plant the phone on a flat surface upside down. A low ceiling, top of a door frame etc. Make sure it's flat and facing upside down. Go to: Settings, Display, Horizontal calibration and calibrate it upside down.
Bingo bango, your broken compass should be fixed. This also cures slow auto rotation
Just tried that. Still as erratic and jumpy as ever.

Hardware problem?
The first time I used Google Maps with EB13 it told me that the compass needed to be calibrated and to move the phone several times in a figure 8 manner. I did it, and the compass has been fine. I'd never seen that before. I hadn't used the compass at all before this, so I don't know if it "fixed" a problem or if I just didn't have a problem, but I thought I'd throw it out there for people who are having problems.

Same for me but it was still broken. X-Plane was unplayable, auto rotation was slow and sometimes unresponsive because the compass was backwards and jumping direction erratically. (download a compass app and check yours) North was south, etc.
The upside down trick 100% cured the issue. Not the figure 8 or the right side up calibration.
*shrug*
Wow! Best find ever! The upsides down calibration worked for my slow gsensor lanscape bug! All this time, rooted was needed for the
"system/bin/sensorcalibutil_yamaha" code to work! Very nice!
I wish I could claim credit for this (the member who deserves all the credit is styles420), and I wish it worked for everyone, but someone found this back when DK28 first leaked. It seems to help with a group of us with sensor data that gets mapped backwards during the flash. It shows up in the compass or google sky maps, but it seems to be a problem with the g-sensors that affects how the compass works.

try downloading GPS Status from the market. Open it and do the calibration tools. Should fix this. Also may improve your GPS (if it isn't doing well)
Possible, but it was the same on my previous epic. I haven't put too much effort into it since I don't really need a compass very often, but it would be nice to have it work for once.

I already have GPS Status. I did that calibration from that again, and it is still messed up. It jumps a little less, but I can turn the phone 90 degrees and the compass rotates 180. Then I turn the compass 90 degrees the same direction, and the compass jumps backwards 90 degrees. I'm having a really hard time figuring out a reason for the pattern. I might have to sit down and draw some compass diagrams.
Worked for me. Fixed slow auto rotate as well

Another issue, maybe?
I wonder if there might be an underlying issue here...
Was doing some research on why my battery life is garbage after EB13.
I hit on this thread because it looks like the compass sensor is consuming a ridiculous amount of CPU... I mean, foregrounded using 7% CPU when nothing else is going on.. like, no compass app or maps being used.
With my Epic pretty much quiescent, top consistently reports it (/system/bin/sensorserver_yamaha) as the highest user. Under DI18, it never even cracked the top ten.

[Q] Proximity/light sensor turns of my screen

Hi!
Ive had a problem with the screen turning of, during calls only, for a couple of months. I think it happend somewhere in July/August.
Now, this question have been asked but there has been no answer that solves this.
There is a solution for Desire HD http://forum.xda-developers.com/showthread.php?t=951858.
I have tried the Proximity screen off http://forum.xda-developers.com/showthread.php?t=624206 for the HD2 but that does not deal with my problem, it did not work for me.
The problem only occurs during calls, the screen shuts of no matter if Iam close to it or not.
The screen does not shut off if I plug in the headset before/in the call and also if there is very very much light before I answer/make a call to the time where I hang up/the other person hangs up.
The screen does not wake up for along time after the call has been ended, unless I put it very very close to a light source ( LED does not work so good, light bulb would do the trick),or the usb charger. If I plug in the headset after the call has ended, the screen is till turned off.
I only have this problem when Iam in android. I have been using AmeriCanAndroid ever since I got the phone in May.
Regarding the Proximity sensor off, I made about 90 different setting combination, Screenoff triggered/not triggered with lockscreen delay immediately/several minutes (CM7 settings) with different values when the screen is covered/uncovered with Advanced task killer on/off.
No matter what I tried the result was either the same or worse.
The interesting thing I found out was the screen (at least for the first seconds) turned off each other time, i.e did not shut off for the first ~10 sec, the next call it shut off immediately.
Is there someone who could create an app/setting for the HD2 so that whatever reaction the phone gives when plugged to charger/headset, regarding the sensor(s), but without actually connecting it, would be a life saver.
This problem is very annoying when Iam in a call and want e.g use the dial/check messages/check the time.
Thank you
Go to your settings, and look for something dealing with your proximity sensor

Thanks for trying to help me, but I have checked everything on the phone.
Anyways, I think this problem is with the proximity sensor because the light sensor seems to work just fine (automatic brightness/backlight settings is responding to the amount of light)
Thanks!
Default settings on CM7 WITH TYPHOONS roms does not have this problem. Perhaps re-create system since it is same since may. Fresh install and all should be well.
Otherwise check for dirt or finger grease smudging over the proximity sensor.
Used to have this problem too on typhoon. Task29 and starting from scratch solved the problems.
Thanks for your reply!
But I dont know anything about TYPHOON roms, and I dont have a reason to change from americanandroid except for the proximity sensor problem.
Iam writing this in hope somebody can include an app or a setting for the HD2 so one can shut off the proximity sensor, I think that would be the best an easiest solution.
Still suggesting you might wipe everything. When I had issues appearing, I started fresh and it fixed it 99% of the time.
Backup your stuff first if needed, then install the newest American Droid and start from scratch.
You might do a nandroid backup before, then if a fresh install doesn't work, you can restore back right before you backed up.
I have the same problem & I couldn't fix it!
using all the sensor monitors in the Market I can't ge any readings from the light & proximity sensors!
in "Phone tester" the sensors read:
Proximity = Near
Light = 10.0 lx
This for covered & uncovered phone - near or far - dark or light!
I'm using: AmeriCanAndroid 110711(sd)
Radio: 2.15.50.14
I think the file /system/lib/hw/sensors.htcleo.so is the problem.

The reason why removing that file, fix the problem, is because you basically tell the system that there are no sensors at all.
Now that would be a good enough solution for me, only downside is that the sensor wich tells the phone to go in landscape mode also stop working.
I think if somebody could edit the script to tell the phone to stop using the proximity/lightsensor then the problem would be solved.
I saw a post where archagel got scripts from HyperDroid
Here
I checked the files, but the names did not match with my files, perhaps someone knows more about this?
archagel said:
I had the same problem, so I got libsensors source from HyperDroid, commented out lines that do proximity sensor initialization and got sensors.leo.so that shows to phone that there are no proximity sensor.
There are 3 identical files in the attachment - simply copy them over into /system/lib/hw on the device.
But, actually, repairing sensor would be better solution...

[Q] Gingerbread Horizontal Calibration

So I used to run /system/bin/sensorcalibutil_yamaha as root to get a more precise horizontal calibration (the option in setting seemed to do nothing). However after upgrading to GB it seems like this executable has been removed and the option is settings still didn't seem to solve my issue. Is there another alternative on a stock GB rom? Maybe they renamed the app?
Download GPS Status from the Market. When you open the app, go to settings. There is an option to calibrate compass. Worked great from mine. Mine is spot on now.
Is there really no longer a built-in calibration app in system settings? Mine worked fine although the phone had to be upside-down like many other people's while using it.

No the built-in Settings -> Display -> Horizontal Calibration still exists. My statement was that it never really worked for me and still doesn't. The only reliable way I had to calibrate was by running the aforementioned yamaha application while running as root.
I've tried the upside down trick and I still get jitters. For instance Words with Friends randomly shakes the tiles, even if my phone is sitting on a table. It's not so bad w/ GB as it was when I got the phone originally but I was able to solve it under Froyo with the yamaha tool and don't seem to have that option in GB :-(

Yeah, I used to use /system/bin/sensorcalibutil_yamaha as well, and it worked very well for increasing the speed/sensitivity of rotation, but seems to be gone in CM7 (Which is built upon AOSP GB 2.3.5). I brought it up in another topic & one of the devs (I forget who) said that there is no known fix right now.
I'll try offtohavasu's tip, but I'm not gonna hold my breath! I've used it before with no success, but I haven't tried it with CM7 yet. Cross your fingers that this is the fix we need!
EDIT: no luck. I tried both the "Compass calibration" (which I didn't expect would do anything for rotation speed/sensitivity, but I tried anyway) and "Calibrate Pitch and Roll," and neither one had any impact.
not working for me either.
My rotation lag is terrible as well, and the upside down / display calibration option has not fixed it. I thought it was just me as this popped up on the last two GB leaks for me. I would love to be able to rotate my phone properly again.
Hate to tease but if I had a computer I could probably whip up a possible fix if I had my computer:/

This certainly seems to be somewhat hardware related (as in, variations in production quality). I had issues back on Eclair or one of the first froyo leaks, including the bacwards compass that initially lead me to the upside-down calibration discovery, but my rotation speed has been fine since sometime around the release of EC05.
But how long of a delay do we each define as lag? When I had issues, I actually had to shake the phone to get the rotation to register... now, it still hesitates for about a second, but I see that at as a check to make sure it was an actual rotation instead of an incidental, momentary tilt of the phone - I would be annoyed if my screen rotated every time the motion sensor detected the slightest movement
Edit: a full second is an exaggeration, I'm seeing more like half a second of hesitation... Just trying to remain accurate

[Q] Auto Rotation Glitch

I'm on a rooted Note 3 (Verizon), running 4.3
Recently I began experiencing the annoying auto rotation glitch. Seems to be completely random too. Restarting the phone removes the glitch - but it eventually comes back. I've tried pretty much everything but nothing gets rid of this glitch other than restarting the phone.
I did find this thread here: http://forum.xda-developers.com/showthread.php?p=53138619
...I'm new to rooting, I see that this solution is for 4.4 so I'm hesitant to try it.
Anyone run into this glitch and found a cure? Will the solution found in that thread work under 4.3? Is it worth a shot to try it (I haven't tried it 'cause I don't know if it'll cause problems since I'm on 4.3)?
You may want to let us know exactly what the glitch is. Does it not rotate? I know on my current build which is stock, it almost always rotates once when I open the browser no matter what orientation the phone is in.

The Note 3 will stop automatically rotating the screen. The thing is, it's totally random. Sometimes it'll stop right away, sometimes it might be fine 'til the end of the day and then it stops.
I've been closely monitoring what apps I'm running when it happens, can't seem to find a culprit.
Restarting the phone fixes the glitch, but it's just annoying to have to restart the phone to get auto rotation back.
I've poured through what seems like hundreds of threads trying to find a fix. I've turned auto rotation on then off of course along with so many other tips and tricks that folks have suggested.
EDIT: But that thread I linked to above was the first one to suggest modifying a file to restore auto rotation. I'm a noob so I just don't want to immediately do that without askin' if it should work for me or not though.

Solution to GPS won't Lock

I've been struggling for months with problems getting a lock with the GPS. It started with Lollipop 5.0.1 but gradually. Then when I installed a 5.1.1 rom, I could no longer get a lock at all. I tried all the fixes I could find. I even Odin'd back to ANJ7 so I could reset the GPS NV with the hidden menu.
Finally I came across a post that was a variation on the advice to tighten the screws on the back of the phone here: https://www.reddit.com/r/galaxynote...e_4_gps_problems_possible_solution_helped_me/. His situation was almost identical to mine so I tried it and it worked - instant GPS Lock! Hope this helps someone. Here is his post (thanks whoever you are!) for convenience:
[–]the_fixit_guy 0 points 3 months ago
I solved this problem on my Note 4 after months of trying nearly everything. The solution is below, but first let me show you what happened and what I tried:
-I had Kit Kat on my ATT Note 4 and no GPS Issues -I upgraded to Lollipop and then eventually started to notice GPS issues, but not right away -I tried all of these in various permutations with some success, but eventually the problem came back: --Rebooting --Deleting cache partition --Removing SD card --Removing SIM
Using GPS Status (free from Chartcross Limited), I would get 0 for satellites 'In Use' and all bars were at 0 signal strength.
I thought either to exchange my phone, but others have tried that to no avail, so I thought it might be Lollipop, but my issues started some time after the upgrade.
Finally, I came across a suggestion to tighten the screws of the phone, but I did it a bit differently because the screws were already tight. Here's what I did to fix it:
-Power off -Remove back cover -Remove battery -Remove SIM -Remove SD card -Remove all screws -Hold top of phone in left-hand and bottom of phone in right-hand and counter-rotate hands in a wringing motion to gently flex the phone. Not too much, but just enough to get things moving slightly. Do this a few times. -Replace SD card -Replace SIM -Place phone face down on a clean soft surface and gently press down with thumbs on every surface except the SIM, SD and battery area. Use firm pressure, but don't overdo it - just enough to reseat whatever is underneath. Also do this on the exposed areas where the metal contacts show through plastic cutouts. -Gently press down on the SIM and SD areas, but do not crush the metal covers - just enough pressure to flex the metal without bending them, and you will hear the SIM contacts make a few sounds - this is ok. -Replace all screws -Replace battery -Replace cover -Power on the phone -If you don't already have GPS Test from Chartcross Limited, install it (you can use any GPS app you like, but this one is free and will show you the signal strengths). -Run GPS Test and wait for a GPS FIX. You should see the satellites on a bar chart with colors, which should be at least yellow or green. Then the status should change to 3D Fix.
Ever since I did this, Google Maps now works (as opposed to location indicator blinking all or most of the time and chewing through my battery). I can drive again!

As have been previously discussed in this forum in very technical detail, changing NTP servers has 0 affect on GPS. What you observed was a placebo effect.

No but no need. Once I did the above my phone's GPS was like it was when the phone was new. It locks instantly. I've since used Maps again and it doesn't miss a turn. I'd almost forgot how good it was. It's made my phone feel brand new again. In retrospect I think I had an intermittent connection that finally failed. Maybe it started when I dropped it. Flexing and pushing down on the back reseated something.

Wow..Who's wound up? What pecker waving? Did you see me show you any kind of attitude? Wow... What crawled up your ass and died?
Yeah sometimes it worked normally. As I said it gradually went bad - working sometimes normally but more and more refusing to work at all. This wasn't a problem of weak signal. The GPS just wouldn't work at all - no update of position for long periods though I'd moved. When I installed the 5.1.1 rom it packed up entirely. Perhaps the heat of the backups and installs in reality finished the tenuous connection I still had. I can see now that it was never a software problem.

I was having problems with the GPS also and after doing research this solution kept popping up being a little skeptical I decided to send the phone to Samsung and was informed the repair would be expensive so finally decided to bite the bullet and try tightening the screws,for the last two months the GPS has worked flawlessly so I can confirm this is a viable solution and before replacing paying for repair it should be tried.
I tried this repair, and gave it thorough testing. My gps has been flawless since.
Thank you!

I just tried this and it didn't work for me.
Removed all the screws, twisted my phone a bunch of times, pushed down everywhere, reassembled it and No change in GPS quality.
I'm not surprised. It won't work for every gps problem, plus you need a bit of luck! I will say that I pressed pretty hard; as hard as I thought I could do without breaking the screen's glass underneath.
