Whoa, I can't understand why people are so mad and rude.

You are not obliged to concur with my test - however, I did not pull it out from my ass - thing you are doing when you speculate that it has been "resaved and recompressed, probably multiple times, and have been rescaled by completely different factors".

No dude, they were not. I got both photos and didn't compress them to generate artifacts. EXIF is stripped because IMGUR does that. The test is to show how it renders the noise in low light.

While I have stated this is not the best comparison test, it's the best someone could come up with until now. I'd be REALLY happy if you could prove me that my unlocked phone hasn't had loss of low light quality since I unlocked it, though.
[Xperia Z2 General] B1nny:
FYI, Imgur compresses images that are over 1MB, so your image has been compressed (unless your source image was under 1MB, which I highly doubt):

http://imgur.com/faq

Also, a better way to compare is to take two images by yourself from the same scene, at the same time. Maybe you know a friend who has a Z2 as well with his/her bootloader still locked. This is because you don't know if the other website modified the images in any way. (EXIF data can be faked very easily btw)

I'm not saying your comparison doesn't make any sense, but you could probably improve it a lot with the things I mentioned above.
[Xperia Z2 General] knoxploration:
Yes, "dude", they were. You didn't shoot both photos, and you have no idea what has been done if anything to one of them. Neither photo is at a native resolution the camera supports, so both photos have been downsamples and/or cropped.

You cannot downsample or crop losslessly, so both photos have been saved using lossy compression, then recompressed and resaved again using lossy compression, at LEAST once and possibly more times.

This "comparison" is totally flawed on every single level, and the only meaningful conclusion that can be drawn from it is that "both locked and unlocked phones can take pictures". Every other conclusion you attempt to draw is utter nonsense.
[Xperia Z2 General] rodritank:
Indeed. Thanks for the input. Like I said, I lack of a second locked phone - so I compared the grain.

I just hope someone will make a new comparison under fair conditions then.

[Xperia Z2 General] paulson881:
first things first, I totally agree with you. Your logic is concrete and your method is scientific, I am impressed.

BUT, can you rephrase your words so that it is less intruding? Although you are the correct one, but these words might lead to keyboard war. Your words are like a dictator, which is not supposed to happen here in XDA. Perhaps if you know more than him, you can GIUDE him to enlightenment:D
[Xperia Z2 General] Einride:
While true that his tone might come off as a bit rude, I'd say that's partially because the OP is very bombastic when he states the following in the first post:

Which, frankly, turns out to be BS.

A "final" test of this would be taking several pictures of several different motives/scenes with the exact same settings, the exact same motive, the exact same lighting and the exact same position, first with a locked bootloader and then with an unlocked bootloader.

A time-consuming task that requires the right equipment and person doing it, which is why there's no definitive answer to this yet.
[Xperia Z2 General] Haldi4803:
Yes, black is black! But... Here it comes...

The Sky is not Black! There are a lot of stars in the sky! You will not find a Black spot on this earth. Not even in a totally closed of room you could create a photo of black with your smartphone, simply because the light of your screen would reflect from the walls!

So for 'nearly' Black pictures, to compare, values like ISO, aperture and shutter speed are most important.

And as you stated before. Most people are that happy to root their new phone, they either don't care or totally forget about Foto quality and noise reduction ^^

That's why there has not been such a test before.

[Moto X Q&A] gcbxda:
i just restore my image backup from June on my motox and all is fine. but a while ago a notification popped up saying something like "a important Google app requires update"

when i touch it in redirected to play store. to Google play service page. there are two buttons: disable, open.

View attachment 2967641

if i click disable i get this message saying some nonsense about device administrator.

View attachment 2967642

when i click OK it just closes.

so i went to settings - security - device admin. and of course there was no Google item there and all the 3 items i had there were NOT selected.

searching was mostly futile as that keyword filled the internet because people flash custom roms and forget to read about the gapps part :) i did found one thread saying that you have to remove all Google accounts before updating this... but if i remove all Google accounts i won't even be able to freaking open the play store...

what am i missing here?

Note 4 Root: OTA Updates & Android 5.0

Hi! I want to root my new Galaxy Note 4, I've already downloaded all the necessary files and I everything but my question is: Should I wait until I get the update to Android 5.0 to root it? Will CF autoroot method work after that? OR if I root it now, will I lose OTA updates? Thanks in advance to anyone who can clarify any of these to me and apologies for my bad english!
[Galaxy Note 4 Q&A, Help & Troubleshooting] Archiimonde:
You're installing CWM automatically when using CF-Root. Google Play is installed on the phone when you buy it, I'm not sure what you mean here.

You have 2 options. Find a stock rom image and flash via Odin, or download Kies 3 from Samsung's home page, and follow the instructions for emergency firmware recovery.

CF-Root currently only works for KitKat. If you wait until after Lollipop is released, you have to wait for an updated version of CF-Root. I think you'll lose OTA updates, but I'm not 100% sure. Either way, you can update manually with Odin if an important update is released, which is as easy as the rooting itself.
[Galaxy Note 4 Q&A, Help & Troubleshooting] caaanaya:
Thanks! And if I update to Android 5.0 Lollipop will I lose root access?
[Galaxy Note 4 Q&A, Help & Troubleshooting] Archiimonde:
Yep :)

This was wrong, sorry. You can e.g. flash a custom kernel to get cwm, or use an app from Google Play.

Hello. I am reasonably experienced when it comes to using custom ROMs (I run them on my Galaxy S2 and Galaxy Tab 10.1) I am no longer able to use OTA Touchwiz updates for my international Note 4. Is there currently a way for me to somehow make that possible again? Apparently people use Triangle Away on older devices, but this doesn't work on my Note 4, so I suppose it's not supported (yet). I welcome all kinds of assistance. Thanks in advance!

Edit: NVM, apparently it's easier than I imagined; just flash a version of Touchwiz via Odin and everything is considered Official again. OTA now works again.

If you had a DE....you would know. You would have bought it straight from Samsung and paid $699.00 for it. Turning on Developer Options does not make a Developer Edition phone.
