[Q] Phantom Taps, Bad Screens?

Does anyone have a solution for phantom taps on your NC?
I'm on my 3rd Nook Color when I pick up the replacement unit this afternoon.
My general issues are phantom taps - or the NC doing things I don't want it to. So far a very poor experience when typing, turning a page in a book, or even just navigating the ui. The whole issue may be me, it happens regardless if I am plugged in or not. I keep a very clean screen so there is very to little gunk.
I do have sweaty palms on occasion but not out of the ordinary. I have other touch devices that have never given me this issue. If anything I think the screen is overly sensitive - hardware or software issue?

Nope it's not just you. Mine has a multitude of issues with the touchscreen...
Essentially I cannot use the touchscreen when the device is plugged into stock charger/cable as wherever I put my finger, a random touch appears somewhere on the x-axis near my finger.
It seems that the device does not like changes in temperature or humidity either when it is unplugged. Using my tablet while cold was impossible, and likewise while it had been warm.
I'm on my second tablet from Best Buy-- the first one had dead pixels galore (enough to make the best buy rep say "dang!"), and now this one has a bad touchscreen and hard to press power button.
However: I purchased one of these for my mother a few days before mine at Barnes and Noble, and it has no issues whatsoever... at least not yet.
I've come to the conclusion that this hardware is quite beta, but I'm willing to give them a chance since it is the best bang for the buck, even if I have to go through a couple of returns... it's honestly almost worth the time for me since a tablet is so valuable for schoolwork.

Fortunately mine does not do this. I think maybe for those that are having this issue it may be able to be fixed in a firmware update.
My EVO had extremely similar problems when it first came out with the touchscreen and not being able to use the dropdown menu while the device wasn't grounded. After a firmware update the phone was great with touch sensitivity.

my first one did this also. so far the second is doing fine, but the first didn't have any problems till the 13th day of owning it.
i'm hoping it's just an issue that can be fixed via software - maybe someone put an incorrect voltage input somewhere.

I was having the same issues. I bought a screen protector and that seemed to solve it. So far, it's been working fine.

I noticed the screen protector stabilized the touchscreen a lot. Before I seem to have a problem finding the sweet spot for a touch. Now it seems better.
However, my phantom pinky is always touching something while I am trying to navigate. As long I only get one finger near the screen, it's fine.
Mine came from B&N.
The only other issue I have is the magnetic clasp in the cover seems to throw the internal compass/magnetometer off a lot.

Considering the Nook has neither I think you are okay.

Then how is it managing to correctly position the screen with Google Sky? Is it just spooky smart?

Mine only has problem when screen gets dirty. Try a screen protector or use gloves.

is there really a compass in this thing? I just assumed there wasn't. if there is I'm buying another tomorrow!

Screen protector helps to solve my problem.

Are you seeing more issues right after cleaning the screen? I see issues then and I think it is because I an using some moisture on the cloth. If I just dust it lightly with a dry cloth and live with a few finger prints there seem to be less of an issue.

Oh well, it could be worse although I don't see how Google data can tell which direction I am facing.

Nor can your Nook Colour.. Using something like TetherGPS would have some heading information, but the NC itself without help would not.
It might show 0, dunno there. Maps for me just shows a dot, if yours is showing different, that'd be... interesting.
For S&G I tried "Compass", it of course FC's immediately like almost all apps that try to use the GPS. Enabled TetherGPS (with no server, just the client) and it ran, but of course no data, no heading, etc.

Is this occuring when the nook is plugged in? sometimes the charger can cause phatom touches with the touchscreen. Cleaning the screen and being on a stable ROM usually gets rid of that problem.

If only I weren't so stupid ...

LOL! Ok, I sat down with it and played for a bit. It appears some tilt sensor is handling the up and down tilt. If you raise the screen over your head, it shows those stars and if you tilt it down, I see what is below the horizon. That is pretty consistent. But it's also "simulating" a compass inadvertently.
By that I mean that if I happen to turn it on facing north, it appears to track as you turn in a circle but it's really just me tilting it and it's rotating he view. If you do it enough it has no clue the direction it's facing.
I'm just glad I figured this out before I got lost in the Amazon.

Just got mine plugged it in and unplugged and within stew minutes phantom touches couldn't even reboot it im on cyanogen mod 7

[Q] Note 3, Google Maps, & Arrow Pointer

All
I've been having a really annoying issue with my Note 3 and Google Maps: the dot-arrow that shows my position is pointing in the wrong direction. Yes it does track me per the gps location but the issue is that as I am driving instead of the screen moving from up to down, usually along the length-wise direction, it moves at an angle or across. The only option I have is to hit the location button so that I can always have the top be North. That's not as good as having the heading pointing to the location of travel. Now, I calibrated and recalibrated the compass with GPS Status App (turns around the axes and figure eights) which seems to have worked for some, I have restarted numerous times even after turning on/off location-based services. I have cleared the cache and the google maps data. I have reinstalled it. I have even checked the compass versus real settings - seems to be pointing in the right direction. I still have the same issue. This is very frustrating and disorienting when driving. Looks like a crab moving angled to sideways across the screen.
I am on the latest Stock KitKat 4.4.2 version and Maps 7.7.0.
So, does everyone have this issue? Does anyone think is is a unique configuration issue? Is this a google maps issue? Any thoughts on how to fix?
PS...other Map Apps seem work fine (but like to use Google Maps due to the excellent traffic option)

If other apps seem fine, it might be Google maps. I don't have that issue, but I use Google maps version 6.14 (the old style with location arrow). The note 3 is notorious for all of its gps issues, but if you have good signal and it doesn't cut out then all I can think of is that GMaps is the culprit.

I noticed this issue too! I believe it has to do with being inside a vehicle. The metal may be interfering with the gps signal. If I sit in my car and hold my phone so it points north, the arrow points south. If I open the door and step out (while still pointing north) the arrow magically flips! I can fix it by doing figure 8's in the car, but what a pain!!

Well, I do agree it is a google maps issue. I wonder if I can install older version to check. It only recently happened to me. I do not think it is an in-car issue because I never had the issue before when I was navigating in the car. Will come back if I can side load an older version of gmaps.
By the way, this issue is all over the internet but none of the foxes suggested seem to work for me.

No luck in getting it fixed. Did back down to earlier version of 7 but still had the same issue. Driving me nuts.

navfree... can preload maps but just uses google search for most things. some things arent great but its getting better. ive had the same issue with google maps. its been super sporadic. not a deal breaker...

So excited when I started reading this thread, figured someone would have a solution...lol Had this problem ever since my GSII Skyrocket, the gps works great but the direction is always off in my car... Can't understand what the problem is. Done the calibration to no effect... Hopefully someone who knows how to fix will pop in and steer us in the right direction...lol

I'm also waiting for a fix for this..
Ever since 7.0 "update" its been like this. I tried everything but no luck.
I'm using Exynos Note 3.
I was using an HTC EVO 3D when I recieved thr 7.0 update. Before it was fine but after the update even my HTC started doing the arrow pointer bug, and its still happening on my Note 3 even after the yesterdays maps 8.0 update. So I'm thinking this is all Google's fault but nobody is admitting anything.

Hit *#0*# , then select sensor, little black compus will have red line in middle on bottom left of screen. Shake phone vigorously, line will turn green..... This will fix that issue;however, if you reboot phone, you will have to do this again.
Hope this helps someone.

Any solution that needs to be applied again after a reboot is not a solution at all (nothing against you, just frustrated at no solution).
I have the same issue as the OP, and GPS status app fixed it, but I lose the fix after a reboot. This is unacceptable and I don't think it's just a few of us experiencing this issue.
Could more people post and say whether they have this issue and if not, how they fixed it?

The issue seems to be resolved by this. I only have to rotate the phone horizontally a couple of times after a reboot and pointers works just fine.

[Q] GPS Issue

Anyone else have issues with their GPS?
Mine seems to get confused about where I am even though I have high accuracy enabled for location.
If I just go by the voice prompts it would get me lost.
It tells me to keep going on a street I've already turned off of.
The map seems right but is as if the gps needs to be calibrated or something.

Mine did this for like 5 minutes and then locked on and was perfect every time since.

Mine is finnicky as well for GPS games like Ingress. It's a noticeable lock on lag difference compared to the HTC One M8 which was pretty much spot on every time without much drift. I hope it'll get patched in the future :]

Sometimes the solid circle inside my GPS icon flashes rapidly and other times the whole icon appears and disappears several times a second. Any idea what's going on with that?

When using Waze to navigate, I often lose GPS lock if the phone is resting on my leg. Returns when I lift the phone.

I downloaded GPS status and did the compass calibration thing.
We'll see if that makes any difference next time I use it.

Compass issues

I picked up the nexus 6 from AT&T a couple days ago and love it but I have one issue. The compass is off by 90 to 180 degrees. If I spin it around enough it usually calibrated itself but only lasts until the next time I start maps.
I've seen a couple of comments indicating similar issues but I'm not sure if it is a hardware issue and should be replaced.
Does the compass work correctly for everyone else?

Same issue here
I have the same issue with my Nexus 6 64Gb blue, bought in Germany from Amazon.de.
Calibration helps but it decalibrates soon, and then the compass is off by 90° or 180°.

That would NOT be a hardware issue. That is entirely software.

Exactly, except that in case of Nexus 6 the calibration only helps for about half an hour. It corrects the compass sensor and it starts behaving as it should, only to start showing random direction when you open Google Maps the next time. I've been testing it for several days, both inside and outside, in different places, running calibration several times a day. In no less than a couple of hours (usually even faster) it goes nuts again.
If you own a Nexus 6 as well, and do NOT have this issue, please let us know where you bought the device and which exact model it was (white or blue? memory size?)
Thank you very much in advance!

Calibration *IS* a software function. You feed corrections into the compass driver to compensate for the magnetic fields generated by the phone itself. If it is losing calibration, it CAN ONLY be a software issue. The data generated by the compass HARDWARE is not affected by calibration. The calibration adjustments are applied to values after they have been received from the hardware by the driver, and before being passed on to userland.

Are you totally certain that this is a function of losing calibration and not of needing a NEW calibration? The problem is that a compass reads magnetic fields. Nearly EVERYTHING generates magnetic fields, ABSOLUTELY EVERYTHING that uses electricity will generate magnetic fields. Everything with IRON in it will generate magnetic fields, typically in line with earth's magnetic field so it won't interfere (much), but if that thing with iron in it is MOVED, it will DEFINITELY interfere for quite a long time until it resets.
What the calibration does, is it tries to sort out all the competing magnetic fields in order to lock in to the true earth magnetic field. If you keep switching the compass on at different locations, then absolutely YES, it will spit out various incorrect values. In fact, if you go get yourself a regular old fashioned magnetic compass (with a needle on a pin in an oil bath) and you move it around, it WILL react to all the different things that produce a magnetic field.
Maybe try going into a forest, calibrating it, sitting around for a few hours (maybe a camp fire?), and then checking if it keeps its calibration.

No, I'm not. Well, here are some possibilities to consider:
1. External magnetic fields affecting the phone in a way the compass goes nuts.
Before Nexus 6, I had Nexus 5 for 1 year and its compass worked perfectly in the same locations where Nexus 6 compass fails: same apartment, same office, same places around the city. Moreover, I don't even remember calibrating my Nexus 5, the compass just worked. Now I have Moto G as a temporary phone as I've sent my N6 back to Amazon, and Moto G compass works excellently as well -- again, no calibration required. So we have at least two devices with compasses working fine in the same environment.
2. Software bug that causes calibration data to be dropped.
I had the compass problem both on stock Lollipop and on CM. I also have a friend who did NOT have any compass issues while running exactly the same setup (first stock, then the same builds of CM) on the same Nexus 6 model. In Android, apps typically can't work with drivers on such a low level that could affect the calibration, and I don't run any special apps (except Google Maps) that do something with the compass. So it CAN be a software bug, but then it has to be very picky. Running a phone on pure CM without Google Maps for several days could be a good test as Maps is the only app that had something to do with a compass on my phone.
3. Some magnetic interference inside the device itself, or the sensor being too sensitive and/or having a hardware problem of its own.
This one seems the most likely to me, as it fits a pattern: the problem happens consistently on one device while never happening on other devices with identical configuration, several users have this problem (there are threads on reddit and other places, too) while the majority seems to be unaffected, and other devices with a compass work just fine in same locations.
Anyway, there obviously ARE devices around which can have a compass working just fine, and be it either a software or a hardware issue with Nexus 6, it's good if more people report a similar issue (or a lack thereof).

I have the same issue. I have calibrated from home and on the road in several states. I does not hold calibration.
I'm road warrior, and this is a real problem when traveling.

Question 90 degree GPS Issue

Hey all,
I moved recently and now rely a lot on google maps (and other location apps) to go to places.
Whine the location of the device fave been spot on, I have an issue with positioning and vector... What I mean is the device reports direction with a 90-degree error. If I am on the crosswalk facing one of its directions, the phone shows me that I'm perpendicular to the crosswalk and when I move up or down the crosswalk, it shows me moving sideways... not sure how to explain it better...
If I'm in a car and moving, the dot moves correctly on the map but I'm being shown as moving sideways on that map...
After doing a Google search on the issue, it seems that other people are also having this problem.
I've tried recalibrating, using the live view to calibrate (which works for a moment and then breaks again) Also tried clearing the cache of google maps, (but other GPS apps are also affected)...
Does anyone know how to deal with this problem?

Try turning off improved accuracy or vice versa...
Clear system cache.

All of this has been tried. even board replacements does not fix it...
it seems to be some kind of a software issue...

Screen rotation is set to manual or automatic? Try switching your settings.
Google Play System Update is up to date? Should at least be from 1st March 2022.

we have a crab in disguise among us... 'transformers~~ shell fish in deguise~~'
jokes aside, the GPS is known to be very unstable. I have the issue come and go... and from what I've heard it's due to signal disturbances.
You'll want to report the issue to Google if you are using Google Maps

Use common sense (or develop it) to navigate.
Constantly being led by a smartphone on the streets is a lousy and dangerous way to live.
Develop a mental picture with critical way points of where you are going and then concentrate on navigating the real world by memory. With practice it becomes 2nd nature.
If it's a complex navigation effort break it down into manageable blocks with start/end way points.
For the car a dedicated GPS is more practical and reliable, but you still need to use common sense for when it glitches... and it will.
GPS is just an aid to navigation... like a map.

Do you have a permanent magnet somewhere inside your phone case, or other source of magnetism that would confuse the on-board magnetic compass?

KingFatty came up with my initial thought. Might be some magnetic interference.
I do know the exact issue you are talking about though. I knew I was facing south (I have an actual compass) but my phone said I was facing east. But I solved it with a simple recalibration. I have to recalibrate at least weekly.
You say you have had board replacements to rule out a hardware issue but if it was a software issue then surely everyone would have it? I can confirm that right now, the orientation is correct on my phone. It could be a firmware issue for your specific device but this requires the manufacturer to fix it.
That leads me to think its some kind of outside interference like a magnet in a case.

Samsung's don't like magnets, truth
It may be the earth's magnetic field in your location. It isn't uniform.
It's actually began a cyclical pole shift which will take hundreds of year to complete. Magnetic anomalies with become more common as the reversal draws closer. I doubt the latter could be the cause but the former could.

I think magnets may indeed be the issue. My bag's phone pocket has a magnet on its latch so it might be the thing confusing the phone. The problem is that from more than 20 different phones I had over the years, the S21 Ultra is the first one to exhibit such side effects from magnets...

I use a car mount with wireless charger, and the mount itself creates a magnetic field that confuses the phone's compass so the phone re-calibrates the compass based on the navigation driving etc. When out of the charger, the phone is still interpreting the compass as though it's in the mount with the magnetic influence, so you just need to recalibrate the compass and it will fix the issue until next time it automatically recalibrates while under the influence of a magnetic field.
That's just how compasses work, they sense existing magnetic fields, and the closer a magnet is to the phone, the stronger the field. If only there was a way to tell the phone you are putting it next to a magnetic field so it knew not to recalibrate itself at that time.
