[General Questions and Answers] Planterz:
Phones (and tablets and such) have an oleophobic coating on the surface of the outer glass layer. This both allows your fingers to slide across it easily with minimal friction (rub your thumb on a window or bottle and you'll feel the difference), and for fingerprints and other crud to be easily wiped away.

Colas contain phosphoric acid to give it that "bite" in the taste. Surely you've also seen or heard about cola being used to clean oil spills on pavement, removing rust, cleaning car battery terminals, and dissolving teeth in school experiments.

I'm sure you can guess what's happened to the oleophobic coating on your poor phone. That's why they invented screen protectors.

[Galaxy Tab S Q&A, Help & Troubleshooting] bsquared938:
Hi there,

Have previously rooted my Samsung Galaxy Tab S using a method that was provided to me in a previous thread I had created.

I have started to wonder recently about the benefits (and reprecussions) of moving apps to external storage (i.e. a micro SD card) using the app Link2SD or similar apps. Also, I am not sure what may happen since I inserted the microSD before I rooted the device, and have been using it for storing downloaded files, large video files etc.

This being said,

I have the following questions about using an app (such as Link2SD) to move the application data as well as applications themselves to the external storage

:

1) Will this drastically impact the performance of the tablet? (i.e. is there a noticeable slowdown, say, when playing games that are moved onto the SD card)?

2) I already have stuff on the micro SD card (moved apps and other personal media I put there myself) . By removing it (safely or unsafely) and then putting it back later, will this "break" some of the apps? I had previously moved some applications to the SD card using the Application Manager in the settings page of the tablet. ....... I am asking this because I am aware that the microSD card may need to be removed to create a 2nd, linux-based partition (such as ext2, ext3 or ext4) so that the Link2SD app can move applications and application data...

3) Since I have already moved some apps onto the microSD card using the tablet's built-in Application Manager (under Settings > Applications), will this create issues if I remove the micro SD card?

4) I have read some stuff saying that the size of the 2nd (linux-based) partition cannot be larger than a certain size (this "certain size" varies based on the articles I run into). Is there a size limit for the 2nd partition that is created on the tablet?

5) Any tips on how to get the microSD formatted to ext4, and is there a preferred format for the 2nd partition? In Linux systems I have set up before, usually the user directories are formatted to ext4, so that's what I was going to do unless there is a good reason to use a different format. Am planning to do the partitioning using gparted in windows

Thanks so much in advance, and sorry for all the questions.....

[T-Mobile LG G4] sohungry:
Hello everyone. I got this phone about two weeks ago and it's been telling me there is an update available this whole time but I haven't done it yet. I've rooted an HTC One and an HTC Evo 3d before and I know in both cases there were times where taking an OTA update made it more difficult to unlock and root your phone. I don't know if that is the case for the G4 but I figured I would ask before I update. So, will taking the update affect my ability to root my G4 or is it safe to just do it now so I don't have to be worried about Stagefright? Thanks in advance for your help!
[T-Mobile LG G4] 20degrees:
Root, twrp, update with the rooted n rom in dev section.

Hey guys!

Just wondering what your guys with Moto display are? For me moto display comes on with any small nudges or vibrations, if I'm sleeping at night and I move an inch it'll come on showing the time. I suppose it's not a huge issue considering it doesn't use much battery but just seems a bit strange that it's so sensitive especially when I'm not actually doing the gesture where I'm reaching for my phone or anything. Has anyone had similar experiences?
[Droid Turbo 2 Q&A, Help & Troubleshooting] Digital DJ:
Yep. =) I guess it's a very sensitive display?
[Galaxy S6 Q&A, Help & Troubleshooting] marcus4004:
Please do the poll :)

I have recently had my phone sent in for repair and have received a “fixed phone” which I believe to still be faulty and Samsung do not seem to want to have anything to do with me.

Every time I take a picture in low light, the image will have diagonal streaks where there is a light in the image (see attached images). Bear in mind that I am standing still when taking these photographs.

Samsung have said the following on the photos attached:

“we would not consider these photo's to indicate a fault with the device or camera but instead how the mobile phone camera operates in low/reduced light.”

The samsung presidential office are adamant that the phone is not faulty, hence I have decided to seek a independent opinion from you guys!

So do you believe that this phone is of Samsung quality? (btw my ipod touch takes better low light than these photos!)

Thanks for your time!

As some people have been asking - the film covering the lens have been removed. From physical inspection the lens is in as new condition.
[Galaxy S6 Q&A, Help & Troubleshooting] marcus4004:
Sample video also showing the low light issue : https://goo.gl/photos/BrLs4KiZG8e9R8Wx7
[Galaxy S6 Q&A, Help & Troubleshooting] :
the camera itself doesn't seem faulty as much as the glass covering it. try cleaning it well before taking any photos
[Galaxy S6 Q&A, Help & Troubleshooting] marcus4004:
Thanks for the reply - the glass is clean on the outside with no visible scratches.

I think the problem is with the lens - maybe not the camera sensor per say.
[Galaxy S6 Q&A, Help & Troubleshooting] grneyez:
Your photos are of unacceptable quality, their is no way that this is the way photo's should come out even in low light. They may be grainy in low light but not what you have shown.

Try to factory reset the phone and see if that yields any better results. If the results are the same then keep pushing Samsung to fix or replace the phone. The images are not representiv of the photos that this phone is capable of taking.
[Galaxy S6 Q&A, Help & Troubleshooting] marcus4004:
Hello - I completely agree! I have already done a FR, Safe mode & diagnostic mode and all produce these images. Samsung just won't budge.

They tried to pass me off by saying it was due to ISO - incredible for a technical company...
[Galaxy S6 Q&A, Help & Troubleshooting] grneyez:
At this point you need to have the phone replaced or repaired. You need to be diligent and keep pushing up the Samsung corporate ladder. You will eventually reach someone who will be able to help.

If there is a consumer afairs agency, or Better Business Bureau contact them also. The more more noise you make the better chance you have of getting your issue resolved.
[Galaxy S6 Q&A, Help & Troubleshooting] royalhobo:
I have just made an account to comment on this thread. The photos you have uploaded are NOT the quality of a S6. I agree with the others - you need to get this replaced. I would not stand for having a phone with such poor image quality.
[Galaxy S6 Q&A, Help & Troubleshooting] marcus4004:
After having this phone repaired by Samsung twice before I was fed up so I went straight to the CEO. The CEO passed me off to the "presidential office" aka Sean Archer.

He has been persistant that the phone is of the correct standard. I do not think I can go any higher in Samsung. I am definatly going to go down other pathways if Sean continues.
[Galaxy S6 Q&A, Help & Troubleshooting] grneyez:
As I stated, contact consumer affairs agencies in your area, it never hurts to get help from them. Good Luck.
[Galaxy S6 Q&A, Help & Troubleshooting] marcus4004:

[Galaxy S6 Q&A, Help & Troubleshooting] Tricks25:
I had this problem before too. But found it it was a smudge on the glass covering the lens so i cleaned it thoroughly. In your case seems to be hardware issue. Goodluck on you problem and yeah keep us posted.
[Galaxy S6 Q&A, Help & Troubleshooting] Rakcoon:
Looks like an amazing effect. Those photos are beautiful! However, it's faulty lol

Did you take off the plastic covering? Customer service should replace your phone, especially if they want to maintain their footing in this competitive and over saturated market.
[Galaxy S6 Q&A, Help & Troubleshooting] marcus4004:
The first few photos look quite good, but when EVERY photo has the effect it gets old very quickly! (Good idea re the plastic covering - sadly that was removed long ago :/ )
[Galaxy S6 Q&A, Help & Troubleshooting] mrjraider:
There is a small glass/screenprotector film applied on both the camera lens as the heartbeat sensor. I think that when you remove the one from the camera lens the pictures will come out just fine :)
[Galaxy S6 Q&A, Help & Troubleshooting] marcus4004:
Hi, I removed those films long ago - but thanks! Do you think that my camera lens/sensor has a problem?
[Galaxy S6 Q&A, Help & Troubleshooting] denNorske:
Yes, highly possible.

I mean, look at the possibilities here, the camera only gets the visuals through one hole that Is made for the camera. It is not the sensor as the focus and sharpness seems to be intact on most of the picture.

What I would suggest I that one of the lenses on the camera has been dirty or is made of low quality, as the light passing through is being spread instead of concentrated into the spots were it appears.

Why does this happen in low light?

That's because the camera is opening the lens a bit more to be able to take in more light in bad light conditions. The more it opens, the more of the lens it uses.

So this is by looking at the pictures, a pretty dysfunctional camera, and something you should not accept being pushed away about. You're having one of the best phones (In terms of specs) out there, do not tolerate this.

Go hard on Samsung, they have plenty of money, and probably have a hard time being nice towards customers. Keep us updated on your progress and eventually feedbacks from Samsung. I had some bad times about Samsung lately too, so I'm curious.

Good luck!

Should get another s6 and have them both take the same picture in low light and than show Samsung the result. If they still say the phone is good throw it in their face, get an iPhone, take the same pic and show them while rubbing it in their face.
[Galaxy S6 Q&A, Help & Troubleshooting] silent_freak:
I had this issue too. It is due to the glass on back. Cleaning with a cotton cloth fixes it for me. Maybe in your case , it is from inside.

Nonetheless, Samsung should fix it even if it requires changing the hump glass or the whole phone. What's the point of having such a capable camera if you can not use it in low light. :(
[Galaxy S6 Q&A, Help & Troubleshooting] marcus4004:
I am pretty sure you have banged the nail on the head! I have sent another email and have included this thread so they can see that it is not just me who thinks the camera is faulty. I will let you know the response! I love their phones, but it seems that Samsung has a lot to learn from the likes of the Nexus devices and Apple in terms of after sale support.

Hope you managed to resolve your issue with Samsung!?
[Galaxy S6 Q&A, Help & Troubleshooting] marcus4004:
I have already compared my photos to an iphone 6 plus taken at the same place and time. They said that they preferred the Samsung picture (obviously) and that the iPhone photo had inaccurate colour representation or some other nonsense. They seem so childish and will not admit fault on their part!

My next step will be to compare my phone to another S6. Good idea.
[Galaxy S6 Q&A, Help & Troubleshooting] marcus4004:
It is coming more and more likely that the issue is indeed with dirt on the camera lens from their inferior repair service. There is no way I am taking the glass off the back in order to fix their fault.
[Galaxy S6 Q&A, Help & Troubleshooting] silent_freak:
No man! You don't need to get your hands dirty. Just shoot a mail to top representative with a url to this thread too so they can see the bad PR they are getting. Make sure to do the same on Twitter. Make a side by side comparison pics from your phone and other and write about it. It will do wonders. :)
[Galaxy S6 Q&A, Help & Troubleshooting] denNorske:
Okay good to hear you sent another mail. If Samsung ever becomes too big to help their customers, they've already lost.

And yeah, I'm working on it too. Hopefully it will get In order, but it's unnecessary to use lots of time and energy when it's 100% clear what the issues are.

[Galaxy S6 Q&A, Help & Troubleshooting] Chegueva:
I believe its the camera , if you already tried cleaning it up and nothing works then i guess the camera is faulty in this case. Get help from other technician and see for yourself what's the issue and if its repairable.

The small lens flare on huge lights looks normal to me, look at the picture i posted the other night: http://postimg.org/image/vxmo9jo1d/full/

As you can see the upper left corner has a bit of a lens flare too.

I dont want to risk putting my phone near very bright light sources because i believe there is a small chance you end up with a burned camera sensor, not sure how sensitive these smartphone sensors are but for example, when snapping photos of sunlight with professional cameras theres a risk to damage the sensor permanently.

I am a photographer and what you say about the camera sensor is totally not true.

To burn a sensor you would need almost light that is UV, and pretty much if it.

Moisture would be gone eventually.

1. If it was moisture, it could be a user fault. But it's not, look at the pictures and think: does it make sense? No.
