Probably stupid but I did it several times and it always works : Speedtest reports much lower wifi speeds when the device is held vertically compared to when it is held horizontally.
Using Wifi N (20 Mhz), I reach 8Mbps close to hotspot for both horizontal & vertical, but when 15m away, I reach 3.5 Mbps horizontally and only 0.8 vertically.
Will probably return it this week !
How about you broadcast a different channel or set your main band to wireless g

Done, with no better results, as mentionned in previous posts.
Just thought that the horizontal / vertical grip was not mentionned before.

I'm finding the 2D accuracy is usually pretty close, but the altitude is all over the place. It's currently reading -4m despite my being a good 8-10m above sea level (including being on the second floor). The other day at the same position, it started at 22m and gradually went down to -2m even though I hadn't moved.
Anyone else seeing this?
well...i don't have that particular problem...but i do get live search aquiring the gps location somewhere COMPLETELY away from where i'm at..almost 6-10 miles away to be exact. I usually do a soft reset and all is good again....google maps usually gets my location on point at all times...jus not as expansive in options like live search
Vertical Accuracy
Vertical accuracy of a gps is never near as good as horizontal accuracy. Its more a function of the way gps works than any inadequacy of your equipment. You should get within about 5 metres horizontally when you lock on 4 or more satellites. But vertical accuracy is rarely better than 20 metres.
For more information about why this is true check out http://weather.gladstonefamily.net/gps_elevation.html
Yes, that is pretty typical of any GPS. I believe it is improved if you have WAAS enabled, but we don't have that.
the GPS program that I have [VitoNavigation] gives an accuracy in ft. on my mogul. Normally it reads above 35 ft accurate. have not tested it yet to see if it really is that far off or if the program is not right...too cold outside
@D accuracy ?

@d fix is just that. If you did not mean 3D fix then not surprised, as 2D is not the Z axis and you need a 3D fix, and it still will not be as accurate in the Z axis but should be better with a 3D than a 2D.
Umm... what?
Soundy,
That last post was a bit over my head too. (no offense intended madman, just that we didn't understand the jargon)
All i know is that the vertical accuracy you are experiencing is, unfortunately, about as good as it gets. Did you check out the link I posted before. It explains that the geo-spacial orientation of the satellites is the problem. To get a horizontal fix of your location, the gps receiver needs to see at least three satellites at different angles from your location and work out by triangulation where you are. Obviously if all three are located close to each other, the triangulation is less accurate and liable to slight - but amplified - inaccuracies in the angles that help your gps calculate your location. If the three satellites are right on the horizon relative to your gps location, at 120 degrees away from each other then you will get maximum accuracy because the angles are big and the slight error in reading these angles is proportionally much smaller.
To get a vertical location fix, the satellites that you lock onto in order to get an accurate fix need to be located at equidistant angular locations relative to your location not just in a horizontal plane like when getting a horizontal fix, but vertically as well. The only way to get the satellites in this orientation relative to your location is to have one of the satellites directly overhead and another three located in a tetrahedron format below the far horizon. Unfortunately the satellite signal cannot penetrate through the earth to get to you, so you have to rely on satellites which are above the horizon. Unfortunately these ones are therefore not located as far away (optimal) from the one directly above and so the calculation of the vertical elevation data suffers.
The same effect occurs on your horizontal accuracy when you have a fix on three or four satellites but they are all in the same part of the sky. Your accuracy, even horizontally will be more inaccurate too. Thats why its better to get 7 or 8 satellites in your sights. Its not just that 7 or 8 give more data than just 3 but mainly because they are more likely to be spaced out around the sky more optimally.
As the satellites move throughout the day, the almost random orientation of the satellites as the follow their own paths means that accuracy will go up and down as the pattern of satellites gets "better" or "worse" relative to your location.
Hope this helps

It does, thanks. I'm typically seeing 6-8 satellites, horizontal (2D) accuracy is usually pretty good... at worst it seems to be 6-10 feet off to the west (ie. it shows my position a little further west than it actually is). It's stranger to me that the altitude seems to "wander" so much - like I say, the one time it started at +22m and slowly went down to -2m... while I was sitting still
My SGS2 screen tilts SLIGHTLY to the right. Once I started to notice this I see this every time I use the phone, and it's getting very annoying.
Is someone else experiencing the same problem? Is this something you would send the phone in to service because of?
Can you provide a photo of your phone showing the problem?
I know of no software issue that causes this (there is a Google Egg that hangs the phone screen output slightly to the right).
It sounds like you could have a hardware screen issue but it would have to be showing on all screens, be that the Home screen or when running any Apps/Games.
I don't know if you can see it. If you look at the bottom of the screen it might be noticeable to you. It's the same way in every screen, so I think it's a hardware problem. It tilts slightly to the right.
Sorry, I can't see any tilt from that photo.
I also measured the angle of the bottom edge of the screen and the Home button.
They are both in alignment with each other.
When the screen is switched off you should see the outlining edge of the display.
Now when you switch on the screen does it fit to this?
It seems to be that to whole frame is is a BIT crooked. I don't know how I can show this accurately when it doesn't show that much.
Are you sure it's not your eyes deceiving you?
Try taking a few more shots (close in at the bottom) and then load the shots up on your PC and look closer...... Try and measure the angle against say the bottom of the phone to see if there is any discrepancy.

I've been staring at the photo for like one minute now. And I don't see it. Maybe if you go closer with the camera?
I can see it the top leans to the right, like the frame is not correct. defo faulty
Out of curiosity, has anyone tried using a ruler? Or a measuring tape (like the free paper ones you get at Ikea if you are afraid of scratching it).
I just did a measurement of my screen to the edge of the outside bezel... Starting from bottom to top..
Bottom from both corners of the screen to the outside bottom bezel: 1.55cm +/- 0.025cm
Bottom of both sides of screen to the outside bezel: 0.45cm +/- 0.025cm
Top of both sides of screen to the outside bezel: 0.45cm +/- 0.025cm
Top from both corners of the screen to the outside top bezel: 1.55cm +/- 0.025cm
Never knew this before, but the screen is dead center of the phone..
I also took a measurement of the diagonal: 4 1/4" or 10.25cm +/- 0.025cm
Height: 9.30cm +/- 0.025cm (both sides)
width: 5.55cm +/- 0.025cm (top & bottom)
My Galaxy S II is perfectly aligned.. I do admit though, after you said it, I felt it was crooked... That's why I ended up taking the above measurements --
I've been noticing a few interesting things with my Galaxy S2 and wanted to know if these things would be something to be concerned off.
1). With faith, I finally updated the firmware to 2.3.5. Now, the yellow tint is gone. However, the areas circled in the pictures attached continue to show the same washed-out effect. Instead of the usual blue color in the Notification Area, the areas circled, show a much pale tone. This becomes very visible in grey backgrounds (i.e. accessing Marketplace and Notifications Area) and low brightness in Browser. I don't know if this is a defect in the display or software related like the Yellow-tint.
2). After updating the firmware, the kernel version has Intratech's username at the end? Is this suppose be like that? I thought the Kernel, would be the same as before as stock. The phone confirms this is a official Samsung Firmware, so i'm guessing I have not rooted yet.
3). At lowest brightness, in complete darkness, if you squint and look very carefully in Notifications Area, you can see a faint vertical line across the Notifications Area-only. Doesn't affect anything else though.
4). If you look carefully at the Notifications Area, 2/3 of the screen is darker, while the right is fairly 1/3 is brighter as indicated by the arrow in the picture attached. Is this a way to compensate for the yellow-tinge on the left?
5). The auto-rotation feature doesn't always work whenever display toggles between verticle and horizontal position. Is this something all users face?
6). Lastly, I'm not getting any close to 4,000 on Quadrant Standard even with virtually nothing running in the background. My scores are only ranging between 3000 and 3500 in Quadrant Standard, is my hardware defective? I never had a situation where temps crossed 40 degrees Celsius. My device is normally maintained at 29 degrees Celsius and on average, 31 degrees Celsius. I feel like the CPU is constantly clocking at various speeds.
Please leave your feedback. Thanks a lot.

For me, nothing dramatic recognizable.
1).
Your pictures do not show me any problems or defects.
But this is subjective and maybe you can see more differences when looking directly on your phone's display.
2).
I can not see Intratech's name in your kernel, but this is nothing to bother as it is still recognized as original / stock kernel.
I also think that your phone is not rooted. But you should know, if you flashed a rooted kernel or used another rooting method (like flashing an insecure kernel, using SuperOneClick ans re-flashing a stock kernel).
3). + 4).
The notification area can be used for adjusting the brightness of the screen (click on the bar at the top ans hold your finger there for a second, then move it to the right to increase or to the left to decrease the brightness) - maybe that's why you can see different areas in the notification bar?!
5).
Auto-rotation is not available in every screen and/or app. It should work in your browser, in email app, in video player, etc..
6).
The benchmark scores depend on many different factors. I have flashed a lot of ROMs and kernels (most of the time official and/or stock ones), and I usually get 3000 - 4000 in Quadrant.
For example, the economy mode reduces the speed of the CPU to get a better battery life. Please be sure to disable such performance "stopper" before running a benchmark.
If you want to reach higher scores, you should look for a custom ROM which is "specialized" for high performance.
Original/stock ROMs usually try to enhance battery life and are not focused on a maximum performance.
Thing is when you look at the area outlined in black, the the color is not equal as to the rest of the screen. Instead, the areas outlined in black appear more pale. This doesn't even affect the overall picture quality, but it is sure visible in lower brightness and in situations like accessing marketplace and notifications area and web browser.
Another thing I noticed is that with medium brightness, you begin to spot a faint horizontal line in a plain white background on the top (it doesn't flicker or go on and off, it's just there). if you put the brightness at full level, that line doesn't even exist, is it software?
and when you set the brightness to lowest, a strange faint blank vertical line appears when you see in pure darkness but only in a confined area of the notifications area. is this amoled-related?
when rotating the screen while in notifications area, I can see faint lines that appear on the sides of the screen; looks to be like ghosting. i've seen other S2's and those lines seem to be permanently fixed regardless of what way you orient the phone. instead of those lines that are permanently fixed, mine just magically disappears, but it takes seconds for it to blend with the current position. hope you know what I mean.
please let me know
thanks again
Hard to tell by the pictures, but if you believe the screen to have a fault, then return it under warranty.
or could it be I'm making it a big deal out of the ordinary? lol
I sense a small variation in the tone in that area of the display (right triangle), before removing the yellow tint by upgrading to 2.3.5, this area used to distract me a lot. is this usual in SAMOLED+ displays?
perhaps, I've uploaded a much clearer photo now. if you look on the bottom left and top right you will see what i mean. is this normal or is something wrong. is this usual with SAMOLED? please let me know, thank you
here are the areas highlighted, please check and let me know, thank you
i have a cross shaped formed in the upper right of my screen tho my phone is a nexus s.its still amoled.i noticed it when having a gray background in a dark room.also when i pull out the keyboard for 5 to 10 seconds then pull down the notification bar while the keyboard is still there i can clearly see image retention of the keyboard in the notification tray.i also see this in market when searching for an app and it loads i can see the retention of the keyboard in the grey background.f
So, I just noticed something that I havrnt read about at all on these forums. If you hold your NOOK from the top right corner(i mean top right corner when in portrait) it can affect your wireless signal strength. It drops me from 2/3 bars to 1/3 bars of wireless signal when located at a distance to my router.
Just thought Id bring it up.

Mine does the same thing, if held in a particular way. Outside of the leather case I have, it is easy to replicate. Inside the case, it's a bit harder...

I'm guessing its something to do with the orientation of the internal antennae.
That's because the Wifi chip/antenna is located near the top right end of the nook. Hence, if you cover it up, the signal weakens.

Wait what? So you are saying, the nook is actually better for left handed people? About time corporate america started paying attention to this very important demographic imho.

Well finally took my prime apart today! Actually took it apart like 10x today haha. The gorilla glass is VERY flexible!
While I was in there I did a few things, mainly looked around.
I first put some dielectric grease on the GPS pad. This had favorable results. I went from 13 sat's in view with 9 in use at 48-64 ft accuracy to 15 sat's with 9 in use and 18-24ft accuracy (with more yellow bars.)
So overall not a huge benefit but still noticeable.
I tried the same thing on wifi with similar results. Good, but not great.
Went from -72 to -63db with 2 bars to -62db to -57db and three bars.
Most people know bars don't tell much of your connection story, however while using the same device at the normal spot (3rd floor on my bed with prime resting on my stomach vertically) I did get better results.
So a fluke? Very possible. Why does it work? No idea, I would imagine it isolates the signal a bit.
Share your thoughts comments and whatnots, just please no IPAD talk =P
