Wondering how many of you have a compass that is accurate through its entire travel? Mine heads in the right direction for about 270 degrees (rotating the phone) and the other 90 it is off by about 30 degrees. I have checked out 4 or 5 others in stores since launch day and they behave exactly the same. I also see this behavior using street view.

I need to build compass for my application.
From reading the documentation it seems there are two reasonable ways of doing this:
Sensor.TYPE_ORIENTATION method: This is the easy way of doing it. The problem with this is it is not accurate. When I compare my reading with Snaptic Compass it is about 10-15 degress off which for my purposes is unacceptable.
Sensor.TYPE_ACCELEROMETER, Sensor.TYPE_MAGNETIC_FIELD and getRotationMatrix() in conjunction with remapCoordinateSystem() and getOrientation() method: The documentation says this "is usually more accurate". The problem is regardless of the delay I register with listener the compass goes crazy even when the device is stationary on flat surface.
I'm not sure if this is the problem - but it could be...sorry for the long post, but could REALLY use your help - and this is the best place to find it! Last night I hooked up my Droid to charge on this charger: Amazon.com: Lenmar ACUSB4 AC Travel Adapter for up to 4 USB Powered Devices (Black): Electronics.I went and checked on it later and it was turned off. This was after about 2 hours. The power button wouldn't work and I had to pull the battery to get it to turn on.
So I was thinking that maybe the charger wasn't good enough. Granted, it's not rated all that high but reviews have people charging an iPod, iPhone, Blackberry, and Kindle all at once with it.
It has the 5V output but a lower MA rating (I think 300ma input is what it says). I have another single port charger that only has 500ma (before people come in and say you NEED 800ma or whatever) and it works fine. Anyhow, I tried to replicate the problem by plugging it back into the charger (I wanted to see if it was the charger, or something I did, like set it down too hard...as I have the business card under the battery trick for the back case, thought maybe I dislodged it and was covering the leads or something), and after 8.5 hours, no problems. Fully charged, it was on this morning when I woke.I would REALLY prefer to have a multiple USB charger (even if it costs 50 bucks or more) because I travel a TON and have a bunch of USB devices (6+) that need charged.
What should I have my GPS settings on to get best location? I think I changed them and now it shows me like 10 blocks from where I am?

View 12 Replies View RelatedThe battery status is horrible. Why does it look like it's at 50% when at 30%? I downloaded an app that puts the percentage in the status bar, but it's at the top left in notifications. Is there an app that replaces the current icon with one with a percentage or, at least, is more accurate? I doubt there is. I didn't find anything on Marketplace or through search.

View 7 Replies View RelatedI've never been able to calibrate my compass since day one for some reason, but the easily rotating screens were driving me nuts and getting annoying. I was messing around yesterday, and tried hitting the Calibrate button like 50 times FAST AS HELL and I got the compass to appear! Doing it the normal way didn't do anything, as the phone would just repaint the screen with the fake phone showing you how to rotate it.After a few rotations, it turned green. I was like, wow, that was easy...until I tested it. My phone now refused to go to landscape at all!! So I tried it again. After another 50 taps, I went throught the same motions, got the red compass folks were complaining about in another thread and tried the solution that worked for some by deleting the market Compass app I got months ago. I went back to settings and...nope, still needs 50 taps and still got a red compass. I did a reboot and a battery pull, and same result. I can no longer get into landscape mode, EVER!!! The only way to get into landscape is if I am playing a game or something, but rotating the phone for web surfing or texting just doesn't work.
View 9 Replies View Relatedi've been a (mostly) happy user of the milestone, as it is called over here, but in the past few days i noticed a problem.the compass in the phone is not only off, but virtually broken. it detects a constant reading "to the upper left", which simply overrides the earth's magnetic field. so, no matter how i turn the phone, north is always between one and two o'clock. by using the amazin tricorder app, i was able to find out that the magnitude of the reading differs significantly depending on the orientation of the phone, reaching almost "100" in the max, and about "65" when the phone is 18o turned. so i cleverly deduced that the magnetic flux sensors are still somehow active; but still, they turn out to be useless to me if they show a constant reading no matter.

Leads to some hilarious yet awkward messages. Example: my friend asked me if I knew so and so. My reply was supposed to be yeah but it came out trash. Guess I need to slow down and proof read a bit more.

View 2 Replies View RelatedI just switched from the HTC eris to the Droid and had no issues with IMAP on the eris which is running 1.5 OS. What's happening is I setup my personal domain email as imap and all works. I mark all messages in the inbox as read. When new email comes in it marks the entire inbox as new. I've deleted the account multiple times and done a hard reset. I even tested this in the store on 2 phones.
Moto doesn't have an answer and I found this thread on the VZ forums Droid IMAP emails always Unread - Verizon | Forums and Blogs - Verizon Community which the OP is using the same hosting company as I am. I've never had a problem on a WinMo, BB or iPhone setting it up the same way. Something seems off but not sure what it is. I've setup GMail via the same mail app and that's working.
I discovered an option in street view that is called "Compass View". Not sure what use it is but I thought it was cool. You have to hold the phone in portrait as opposed to landscape for the compass to work...check it out.

View 4 Replies View RelatedI noticed that when I am lookinh at google map (satellite or normal), when I turn the phone the map will not stay to point to the same direction. It turns with the phone. Is this the way it should be?
I also downloaded the Compass application. and it behaves kind of wierd: holding the phone horizonally, I turn around. The compass should keep pointing to the north regardless how I turn. Mine is all over the place. If I point the phone to NE, it does show the N direction but when I try to turn the phone to point to the North it goes all over the place.
This is regardless GPS on or off. I am still at 1.5...
I see people talk about the compass in google map but i don't have the compass option anywhere. Am i missing something?....

View 2 Replies View RelatedI'm just wondering if this is normal: I can go into an app like Google Maps and drop down into street view with the compass view enabled. I'll see that the view will really only point one way and jerk around that one direction as I move it around. I'll then calibrate the compass using the figure 8 method and then street view will work properly. If I then exit back to the home screen and load up say LAYER I'll have the same problem. The compass will point in one direction and jerk around it until it's recalibrate again. It's more of an annoyance really as I basically have to recalibrate it every time I open up an app that uses it. Just wondering if others are having this issue. I've talked to a few i phone friends and other than the occasional recalibration they don't seem to have this issue.
