[Atrix 4G Q&A, Help & Troubleshooting] neonic:
I've seem many threads about it, but couldn't really find a solution.

I just pulled out my sdcard to do some updates in my rom (I was running Th3Bill's miui v4).

I've copied a couple of .zips to try, and when I inserted back, my I /sdcard wasn't mounting.

I've tried to format in windows (fast and normal mode); I've putted this very same card in my tabled (xoom2 me) and it was working fine.

I've tried to run format /sdcard in cwm. same error mounting;

I went to advance > show log:

Maybe is there some pins not working in my phone? Because I've tried another micro sd and got same error! :(

Thanks in advance!
[Atrix 4G Q&A, Help & Troubleshooting] ravilov:
Sounds like you really do have some issues with the built-in card slot. Try inspecting it visually, maybe there is some visible damage. Other than that, I'm not sure what can you do... Maybe claim warranty on it?

You should also never run random commands if you don't have at least some idea what they do. Those commands have nothing to do with fixing the sdcard, luckily for you they didn't work.
[Atrix 4G Q&A, Help & Troubleshooting] neonic:
Well, Actually those commands weren't trying to fix it, and I know what ls does, I wasn't much sure about how ln works, but I know that it wouldn't damage my stuff. :P

I just checked some stuff here, it seems to be a hardware issue indeed, when I put my nail under the card, it reads! Unfortunately I can't claim warranty. I bought this phone used, via ebay, like and year ago, from a seller in USA (I'm in Brazil). I'll try to arrange some workaround (maybe some paper under it might work,...) and hope it works properly.

[Nexus 7 General] drumtrucker:
My plan was to add the 7 to my array of GPS devices, mostly to get traffic info. bought a windshield mount intended for landscape use, which is how I want to use it. Put it in the mount, fired up Maps and started to drive away and the screen was suddenly off... hit the button, but nothing... hit the button again and it came back on. Started to leave again and screen went off again (way sooner than it is set to).

Pulled over, took off my sunglasses and instantly it was back on.... hmmm. Apparently, something that is not mentioned in any review or specification that I saw... the friggin' screen is POLARIZED! As are all my sunglasses.

If you are planning to use in landscape mode in the sun, be prepared to not be able to wear polarized sunglasses.

I still am really liking my new 7, but not luvin' it as much as I planned on.
[Nexus 7 General] Hwaiting:
I think that's the case with polarized glasses and all LCD screens isn't it?
[Nexus 7 General] drumtrucker:
I've been trying to remember if I have ever tried looking at any of my phones in landscape while wearing sunglasses. Will check tomorrow.
[Nexus 7 General] japzone:
Exactly. This is a notorious problem with any LCD screen. My Nook Color gets blacked out in portrait and my Nexus 7 gets blacked out in landscape. It's a problem that's common and not Google's or Asus's fault. You'll just have to deal with it. Most Navigation apps I found use portrait by default anyway.
[Nexus 7 General] mwalt2:
It's your sunglasses, not the nexus 7. Get some cheaper sunglasses :).
[Nexus 7 General] x-magic:
Well, you may try portrait mode or just use a navi app with voice navigation. :o

It seems not only for Nexus 7's LCD, a lot of other LCDs are encountering the same problem with sunglasses.
[Nexus 7 General] db1911:
This is the case with all LCD screens and polarized sunglasses. Had a pilot new to an aircraft with LCD screens complain that the screens were broken. When I looked everything was perfect. I looked at him to see if he was trying to be funny, then realized that he still had his sunglasses on. I asked if they were polarized then told him to take them off a second. Sure enough, problem solved.
[Nexus 7 General] jaycustom:
Yes I noticed that! No big deal for me though, thankfully. I know for a fact it didn't happen on my Transformer Prime or Wildfire S. In fact, I've never noticed it with any of my tablets or phones. Weird though how it's only landscape mode :)
[Nexus 7 General] JSLEnterprises:
Ips slcd/slcdII's .... Yep.
[Nexus 7 General] paulsam7:
No, not weird at all. Think about what a polarizing lens does - it's like a million microscopic parallel lines running one direction. When you have 2 lenses (screen and sunglasses), rotating one or the other so the lines are perpendicular to each other causes the image to black out. If the lines are all running in the same direction, there's no interference.
[Nexus 7 General] jcffrcy:
This really doesn't have anything to do with Navigation on the device

[Nexus 7 General] drumtrucker:
It does if you are planning on using during the day and wear polarized sunglasses and want to use in landscape mode. I didn't want to try to put all that in title.

When I get my Proclip holder when they come out, I will be able to use in portrait. The generic cheapee holder I got to use in meantime is only usable in landscape.
[Nexus 7 General] drumtrucker:
I tried with my Droid Bionic today and it does NOT go blank when turned, so it must NOT be polarized.

[Nexus 7 General] buellwinkle:
I never buy polarized sunglasses. They are so annoying, especially if you rid motorcycles and use a full face helmet. Even in a car, the dash is plastic and in some cars you get a rainbow effect. If you buy decent sunglasses, you don't need them to be polarized. I use Sergenti drivers and they are the best for me.
[Nexus 7 General] Matterhorn:
This^

I only wear polarized sunglasses when protecting my eyes from water glare. Many cars have ploarized windows that look blotchy when wearing Polarized sunglasses. I never wear them when riding my motorcycle because they can block puddles of water and pot holes from being seen in the road. I can't see the radio display in the car when wearing them either.

Get another pair of glasses with good coatings.
[Nexus 7 General] drumtrucker:
Hadn't thought to try my Serengeti's, THANKS. they are NOT polarized and will go back to being my primary pair.

Some interesting comments and info generated in here.
[Nexus 7 General] ahavens17:
I saw this brought up in this forum previously and in other forums, with polarized glasses being an issue. I wear a pair of polarized glasses while driving almost every day. I also use the nexus 7 almost exclusively in my car, and its always locked in landscape mode. I haven't had any issues with being able to use it or seeing the screen in any app. Everything seems to display fine for me?
[Nexus 7 General] drumtrucker:
I am skeptical that your sunglasses are actually polarized...
[Nexus 7 General] Element515:
It's not that the screen is polarized exactly. All LCD screens just use a filter that allows light to go through in one direction. I'm pretty sure that's how you create black on a LCD, it will shift and no light escapes. The back light of an LCD is always on.

You could try turning the Nexus 7 upside down to what direction you had it. That will probably let you see the screen. It may be a little darker than normal though. I like polarized sunglasses for day driving because it stops glare so well and the glare kills my eyes. I never had problems not seeing potholes or puddles though...
[Nexus 7 General] PhxkinMassacre:
THATS SO WEIRD!! hahaha i never noticed that. i grabbed my polarized glasses from the closet, dusted them off, and stared at my screen and was instantly mesmerized haha
[Nexus 7 General] ahavens17:
They are Oakley Gascans that say Polarized on the left lense, they look just like these......
[Nexus 7 General] Matterhorn:
Since water is clear, the only way we can see it is if there is a reflection of light on the surface. Given the right angle,

polarized lenses can completely eliminate the reflection, not a big deal in a car, but it could be deadly on a motorcycle.
[Nexus 7 General] drhunter:
I dont know if it's because my polarised sunglasses are cheap but they dont completely block out the screens on my galaxy tab or one x. They do make the colours a bit dreamy when i turn them between portrait and landscape. I wonder if sunglasses can have either circular or straight polarisation like camera filters and this is what causes the differences?
[Nexus 7 General] generationgav:
Rotate your nexus around, I find my phone is polarised at around a 30degree angle; so works in landscape and portrait with my glasses on, just not at a 30 degree angle!

If it does nothing; then think your sunglasses actually aren't polarised!

Sunglasses should always be polarised the same way (horizontally) as this stops road glare (vertical glare essentially) but screens won't always be polarized in the same way; no reason for them to be.

I wear polarized sunglasses always whilst driving, and the only downside I have is I have a perspex section on my rear windscreen which turns into a rainbow!

[Nexus 7 General] galaxyjeff:
Zz top :)
[Nexus 7 General] Jroyd:
If anyone's interested in the scientific explanation, here it is:

Light starts out with no polarization. If you use the string analogy to light, non-polarized light is like a string being shaken in all directions - up, down, left, and right. When a polarizer is used it's like feeding that string through a grate. It limits the light (string) to only one kind of motion. If the polarizer is oriented with the grate openings being vertical, the string can only vibrate up and down. All side-to-side vibration is blocked. If you have two polarizers you can control how much light gets through. If the filters are aligned (have their "slots" going the same way), then about 50% of the light gets through. If one of the filters is rotated, less light gets through until the minimum amount is achieved at 90-degrees of rotation. One filter is blocking all the horizontal waves and the other filter is blocking all the vertical waves.

LCD screens work because the "liquid crystal" is a substance that can change the orientation of it's polarization depending on the electric field applied across it. It's like electrically rotating one of the polarizers. All LCD screens start with a polarizing filter blocking all light that doesn't vibrate in the orientation of the filter. Let's say that orientation is horizontal. Now the LCD material starts out being polarized horizontally, so all the polarized light from the other filter goes through. As electricity is applied to the liquid crystal material, it starts rotating it's polarization angle until at some point most of the light is blocked.

Most polarized sunglasses are vertically polarized because the worst types of glare are horizontally polarized. But if your LCD's polarizer is horizontally polarized in the landscape mode, you won't be able to see anything - the vertically polarized sunglasses block out the horizontally polarized light from the display. You must rotate it to the portrait orientation where the display's polarizer is now oriented vertically to match the sunglasses before you can view your display.

If you must use sunglasses with a display, you should consider technologies that don't use polarizers, like LED (AmoLED) or plasma.

(BTW, this type of polarization is called "linear". There is another type of polarization which is called "circular". Photographers will probably know the difference between the two. Circular can be "left hand" or "right hand" polarized. It's what's used in the 3D glasses you get at the movies. Two projectors are shooting two images onto the same screen, but one image is left-hand polarized and the other is right. The benefit of circular polarization is that it doesn't matter if you tilt your head. The left and right images still make it to the same eyes. Unfortunately, there are no liquid crystal materials that can shift circular polarization. Otherwise we could have LCD displays that are immune to being blocked by sunglasses.)
[Nexus 7 General] e.mote:
>Otherwise we could have LCD displays that are immune to being blocked by sunglasses.

We already have. Tablets/phones are used in either portrait or landscape orientation. Some devices (iPhone) are polarized at 45-deg angle, which avoid the "sunglass blockage" effect. See video:

[YOUTUBE]78GdcXCM9nk[/YOUTUBE]
[Nexus 7 General] Chinpokomon:
Good advice, but AMOLED screens for some reason still have a polarized filter on them. I've had the blacked out screen on my Nexus One, my Nexus S, and my Galaxy Nexus. On all 3 devices, it has been at a 45 degree rotation, so it isn't a huge problem for me in either portrait or landscape... but still there for a display technology that doesn't seem like it would need a filter.

I'd love to know what phone or tablet you've been using that has a plasma display. Battery life on it must be abysmal. :P

The devices with a nuclear power source in them work great, great picture, never need to plug in, but after a while the radiation burns become a bit of a drag.
[Nexus 7 General] Milamber33:
This is frustrating. I don't suppose there's any kind of film we could put over the screen to convert the polarisation to something else, is there?
[Nexus 7 General] drumtrucker:
I just switched to some quality non-polarized glasses...
[Nexus 7 General] Milamber33:
I'm somewhat hypersensitive, and I'm also kind of broke. Any recommendations on good sunglasses which won't black out the Nexus 7 screen for less than $100? :)
[Nexus 7 General] Matterhorn:
I think that the Serengeti Drivers are the best sunglasses for driving that money can buy. While they are normally quite expensive at full retail price, I've often seen them at Big Five for well under $100. Look for the non-polarized models ;)

Edit: Try amazon, "Drivers" from $74.95
[Nexus 7 General] Milamber33:
Hmmm... Can't find any for that price, but it looks like they mainly use a brownish tint. I'm much more inclined towards a blue tint, if anything. I'll have to look around and see what I can find.
[Nexus 7 General] TeamAlpha:
Nice video. Didn't know sunglasses could have that effect!
[Nexus 7 General] drumtrucker:
I got a pair at Sam's Club a couple of years ago for $85
[Nexus 7 General] Souai:
has anyone confirmed that its actually the glass itself?

i wouldve thought that it was because of the panel. the nexus 7 uses an IPS panel, and in IPS panels, all the pixels/subpixels are all parallel/plane-polarised (The subpixels are lines, not dots). given that all the pixels are somewhat plane polarised, it could be the reason why the polarised glasses would nullify the image being displayed since polarised glasses are supposed to nullify light on a particular plane.

i could be wrong though.
[Nexus 7 General] Entropy512:
Yup. I'm guessing that the N7 is just polarized differently from what the OP is used to.

Similarly, if a person's glasses polarize the light differently than another's, the "bad" orientation will vary.

Yeah, the main reason to use polarized glasses is to see through reflections on glass or water. Polarized glasses are VERY popular with fishermen for this reason.

Your glasses might be polarized in a different orientation than the OP.

And in general: While it is theoretically possible for an LCD screen to generate circular-polarized light, it would require an additional precision layer IN FRONT of the outermost polarizer of the screen. (Putting the layer in between the LCD's polarizers would render it nonfunctional.) This is the same technique used by circular polarizers for autofocus cameras - polarized light screws up AF sensors, so CP filters consist of:

1) A standard linear polarizer, so that the filter reacts to incoming polarized light just like a normal linear polarizing filter would

2) An additional optical layer between the camera and the linear polarizer that converts the linearly polarized light to circularly polarized light

A layer that meets the needs for layer 2) on a 7" screen would be prohibitively expensive - in order to not cause visual artifacts it would likely be as expensive as the device if not more expensive.
[Nexus 7 General] zoglog:
Haha, I didn't realize this until I got google glasses. I was trying to watch a netflix video and then WTF!

This is the same with the nexus 5
[Nexus 7 General] mozart:
SOLVED (partly): use a matte / anti gl;are screen protector

I had the same problem with nexus 7 2012 and 2013. Reasoned that enough distortion / scattering of the polarised light would (at least partly) depolarise it. So tried a matte screen protector and that does the job, when you wear polaroids! But not completely.... The screen will remain darker than without polaroids. I have not tried different brands, but it the one I used on the 2012 was better than the one on the 2013 model (Threw away the packaging... sorry.)

GUYS. I'm getting an S3 in a couple of weeks!!!! :D so pumped.

I'm coming from an Optimus V. Development on that phone is FANTASTIC, but I have terrible service in my hometown, and let's face it: this phone is 29395x better.

I've never really used xda much, because androidcentral is good for the OV. I checked out the ac forum for the s3, and it's awful in comparison. So I thought...I'd better get over to xda :)

I have a few very random questions...

I hope it's okay that I post them here...

1. What are flamers and trolls?? lol.

2. I saw a video on how to easily root the Att Galaxy S3. Seemed simple enough. However, what is this talk of 'tripping a flash counter'?? is it okay to trip the flash counter, and can I reset that later if I wanna go back to stock??

3. I guess cwm is probably the best(favorited) recovery to use??

Thanks to anyone who can answer my questions :)
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] kschumake83:
1. people who are rude and ignorant.

2. Use the no trip root method and everything should be fine. Tripping a flash counter is a way for att/samsung to know that you messed with your phone, it can be a problem for warranty returns, but there is an app called triangle away that should reset this. I havent tried it so I personaly cannot confirm.

3. there was a little bit of argument on which recovery was better when there was the missing imei problem, now that it is solved it doesn't really matter (all personal preference). But please don't forget to do a NV backup or at least a backup of your Imei no.

and by the way welcome to xda it is a great place for information and if you do searches first and post in the propper section the people here are great.
