[Q] how to open the back cover

Hello
I need to open the back cover of the device to cover the camera.
Has anyone already done it? Is there a video to this?

Not a video mate, but photos etc: http://www.ifixit.com/Teardown/Nexus+4+Teardown/11781/2

Why do you need to cover the camera?

Seems like tape. Or maybe even a sharpie would do the trick... A sharpie would be permanent until you rubbed it off with some rubbing alcohol.

A lot of government buildings don't permit camera phones in the workplace. Same with a lot of private defense or research firms. OP probably isn't allowed to have a camera in his workplace, but loves the phone. A few years ago–to fill this small but certain niche–RIM made BlackBerry phones without cameras that were otherwise identical to their camera phone counterparts.
Tbh, the camera sucks. White balance compensation is worse than it is on my original Galaxy S. Pixels don't really mean that much when the picture is poor quality. I can't imagine how bad the camera is on Galaxy Nexus phones if the 4 is considered to have significantly improved optics.

I find the picture quality to be better than my S2 international. But I'm no optic guru.

Actually, I noticed that outdoor photos are acceptable. At night, with the standard lighting you'd expect from any venue or abode, the white balance is terribly far off.

Is it possible to turn off the camera by software?
I mean when I click the icon of the camera, the camera will not work at all.

Root. And then use Titanium to freeze or un install unwanted stuff.

If i do the root and freez or uninstall the camera the other application that use with the camera still can work with the camera ?

No Apps that relay on a camera app will work, but apps with their own camera app (like PicsArt) propably will.

I just removed the back cover to play around. Really pretty easy.
1. Remove the SIM card tray, set it aside
2. Remove the two Torx (size 5) screws on the bottom of the phone.
3. Use a prying tool around the phone to pop the back cover straight off (I used a guitar pick and a small flathead screwdriver)
When you remove the back panel, it would be quite easy to put a little piece of paper to cover the camera.
However, even with the back camera covered, the front camera could still be used to take pictures... and removing/covering the front-facing camera is a lot more involving tear down process. I think a software mod would be your best bet.

Here is a great youtube on disassembly and reassembly of the Nexus4.

Pinch to zoom quick sand?

Thinking about the N4 as a secondary phone but I played with one in the T-Mobile store and noticed that pinch to zoom seemed to be pretty unresponsive and disappointing and that's putting it lightly. When pinching to zoom it felt as if I was moving my fingers through quick sand. It was as if my fingers had to literally transverse half of the entire screen before the phone started to react. Can anyone else confirm this? Like I said, this will be my secondary phone and my primary will be an iPhone 5 so I will going back and forth between the 2 phones often which will make the poor responsiveness even more noticeable and bloody annoying since the iPhone is very responsive and accurate in this department. So now I'm rethinking my purchase of this phone. Again can anyone confirm this??? Thanks

mine doesn't do this. it is very responsive.. are you talking about having to go out farther when zooming in? i think they designed the zoom in to occur after your fingers have spread over a certain distance so you don't accidentally zoom in when you don't mean to.

Its like people are just finding reason not to buy this phone cause it has real issues or they just like to complain....personal I think your all crazy . My coworker got his nexus 4 last week and its ****ing awesome the camera in HDR mode is amazing the data speeds are top notch and the screen is responsive. I don't know it everyone and there mama was playing with the display phone at T-Mobile ,but here a story I was playing with a Gs3 at T-Mobile and found pictures of a girls ***** on it .

There was another thread on this yesterday - this is actually Google almost certainly designing around someone else's patent on touchscreen usage. They probably figured that what was going on in older versions was too close to Apple's or someone else's precise method for interpreting multitouch input, so they designed something effective but different enough to avoid litigation. There's a reason why neither Apple nor Microsoft have sued Google directly over Android - Google designs around patents pretty well.

I hear ya, but even still it'd pretty annoying and making me think before I buy. Honestly I'm a stock app kinda guy. I like the stock apps, I actually want to use Chrome but I can't, I want to use the stock gallery since it would be more integrated but I can't without this bug/feature this will also make using Google maps bloody annoying more than anything as when using maps there is a lot of zooming in and out. I'm wondering if other ROMs have this issue with the N4 or not.... Hmmm... That would be an indicator if there was more of a real issue/hardware level issue or not. Wondering if Cyanogen, Paranoid, or AOKP would have the same issue...

this is such a moot issue based completely on software filtering/calibration of your touches. Capacitors are hyper sensitive to touches, so much so that you have to tone it down and filter out all the noise... You can easily go into the software and figure out where the pinch-zoom controls are and fix them...
I am running codefireX's build and my pinch to zoom works perfectly in gallery, chrome, maps, camera. Registers my touch input no mater what I try.
If this is a deal breaker for you, I would be more worried about thermal throttling issues tbh... Those are actually hardware related.

So you're saying right out of the box you can go into settings and configure pin h to zoom to react immediately rather than after transversing half the screen before it starts reacting?

Well, this is xda developers where we hack software and improve it for our own uses. Its part of the fun. You would have to get into the kernel for that

yes i mean the two white lines on the edge of the photo. it usually happens when taking pictures in dark environments. i also have camera zoom fx on my phone and tried that and the lines still appear.

anyone else have this issue?
Sent from my Nexus 4 using xda app-developers app

I am. It seems to be a bug cuz it happens randomly. Can't really replicate it. Tends to happen after messing with zoom.
Sent from my Nexus 4 using xda premium

I had several pictures get funky on me the other day after messing with the zoom. sucks because they were of my little boys birthday, no idea what happens

Same issue on both of my phones and it happens with my friend as well. I figured out a way to reproduce this. Turn flash off and take the image in low light. For example with the room lights off and just the lighting of your monitor will do it. The darker the better. Doing it this way seems to trigger it 8-9/10 times. My friend tested while at work with office, but was still able to trigger it taking pictures of a picture of the serial number on the bottom of his laptop. No zooming was used.
The lines that come up on the right are always 2nd, 3rd, or 4th pixel from the right. On some occasions I have been able to get it to come up as the 2nd and 4th at the same time. On the left side it seems to always come up between the 16th and 20th pixel from the left. I will have to look closer at all of the images to confirm it is always like this.
I am not even sure what to do now...

Thanks for bringing it up.
I just noticed it as well.

I'm also seeing this! bugs the **** out of me!

Mine as well

Kinda odd that since the 4.2.2 update I have begun to experience this bug for the first time as well.

Anyone notice this issue on any other camera app besides the stock?

I hadn't noticed, but mine does the exact same thing. I could always crop that out I guess...
What's worse is the blurring effect I get. You really see it on the hand and ear. Anybody have this or know how to fix? Stock, rooted. Happens on 4.2.1 and 4.2.2

Turn off HDR. Since it averages three images, it's not good for moving subjects

Just tested it on Camera Zoom FX app using TTZip's steps and was able to reproduce the problem there too. Could this be considered a hardware defect?

Also experiencing this.

[Q] nexus 4 camera

We all know that N4 has a very bad camera..specially in low light photos..photos have very much dots..They seems good on mobile but when zoomed even a little its pathetic.
Was anyone able to find out what the issue is..? is it software or hardware..?
If its software related than is there any solution..?

Low light noise, no tap to snap picture, horrendous flash photos.
It's just not as good as the Galaxy S2+ I was going to sell.
The camera is the biggest disappointment for me as a one week N4 owner. I'm seriously considering selling the phone.
I tried the Moto X apk, which seemed to be a little better on the noise front, but I can't live with that aspect ratio. "Focal" was even worse than the stock camera.

I don't in any way think the N4 has a terrible camera. The pictures of takes for me at least are clear and sharp.. Way better than my S2 and honestly look just as good as my brothers Optimus g and NY wife's Note 2..

Yea, I concur. I'm able to take great pictures with this phone. I'm not sure what the issue is. I mean I did come from the Evo 4G to this though, that phone had so many camera issues so I guess anything is better.

After reading around the subject, the only thing I've that gives me any hope is someone suggested using Snap Camera HDR app and fixing the ISO at 100. I'll be giving it a try in the hope of reducing noise in the pictures my N4 makes. Ta-ta, PmT
I am not expecting a 5DmkIII quality but I was expecting the camera to be as good as the one on my Galaxy S2 Plus (also 8MP).

you dont have to tap the screen. long press the shoot button until its focused, then release. or in 4.3, you can hold down the down volume button then releae when focused.
btw some recent photos..

This phone sold for $200, of you want better camera you're going to have to shell out more money for other phones with better camera.
If you want less noise in low light shoot with iso 100. Or get n HTC One.

Blurry pictures

Yes - it's been driving me crazy... most of the time the pictures come out blurry. I've been messing around with different modes/settings and I cannot get a consistent clear picture. Pretty frustrating!

Yes, absolutely notice this. Brought it up in the other thread but no one thought it was worth checking. Have done tons of side by sides with Note 2 and honestly this camera is very touchy. Has a tiny field and it's often hard to see where that is in the pics. I really hope the camera gets a software update and it's not hardware because the camera has been the only thing I'm on the fence about. When you zoom in, even in good light, things in the taken pic get blurry and almost look like they have an effect.

I can hold my hand a little away from the camera a bit and it won't focus on it. If I tap to make it focus it sometimes turns green like it did but my hand is still blurry.
I hope they push a SW fix soon.
I don't understand it. How can you not catch some of this before release? Camera is a basic function of a smart phone...

Oh well, time shall tell I guess. Sprint won't help I'm sure given how slow they are to push updates too...
Anyone mess with any video? How's that, clear, blurry mixture mess? lol
That prob has ability to be better or worse I guess. You've got 1080P mode and 4K HD, which when enabled seems to kill off a number of features.
I've not messed with it yet but just wondering.
