[Galaxy S 4 Q&A, Help & Troubleshooting] JmJ17:
I think that it is a good idea

My versions are:

I9505XXUAMDE

HW Rev.: MP 0.900
[Galaxy S 4 Q&A, Help & Troubleshooting] DanteSSS333:
Well you have the I9500, so hardware revisions aren´t really comparable in this case. I think the I9505s all got the same revision.
[Galaxy S 4 Q&A, Help & Troubleshooting] D.O.C:
I have .900 hardware rev, and I have the "smudge" in my device aswell (honestly I had not seen it until I purposedly looked for it). I am not a hardware guy, but I do have my suspicion about this.

It happens outside touchwiz aswell, so it is not a touchwiz issue. (Scroll vertically in nova)

It happens only on non white over black background (it is more noticeable in grey shadings). Non black background doesnt have this behaviour.

From my understanding, this could be the pixel arrangement (diamond shape) in our amoled screens. It could also be the refresh rate or we could need an updated set of drivers (increase gpu mhz).

Blacks in my screen are pure black (I cannot tell where the s4 is in a dark room with it turned on and displaying black screen). So, if leds are truly off, it is likely that, in order to turn on, blue leds come on first, then the rest follow in order to display a shade of gray (supercurio will most likely know about this, will try to get in touch with him to ask his opinion)

What I mean is, I think all s4 screens are like this and it aint a reason to return it ( at least not for me, since it doesnt interfere with my reading while scrolling).

Now, if samsung accepts this "issue" by making amoled displays in future batches of the device that doesnt have this, then I will most likely exchange it. For now, I guess I have to wait for someone to upload a video to judge for myself if some batches doesnt have this.

Please stop calling fellow users "liers" as they might not perceive it happening.
[Galaxy S 4 Q&A, Help & Troubleshooting] shortie1987:
I agree with some of your points on what this could be, but would like to point out that OLED displays dont use LEDs at all. They work in a similar way to Plasma screens.

I have tried to record a video for you all as my device is rooted, but I cant get screencast to work properly, it just records a black screen...
[Galaxy S 4 Q&A, Help & Troubleshooting] roguex:
I was thinking the same thing. I just tested my S3 and it also displays the same effect although it's very very hard to notice, but it's there!

I think the S4 is turning off the blacks completely, and it takes a fraction longer to turn back on than if the pixel were already on and displaying black/very dark grey.
[Galaxy S 4 Q&A, Help & Troubleshooting] shortie1987:
I would imagine this is a software issue in all honesty. Although it doesn't really bother me, it would be nice to see Samsung resolve it at some point soon. It almost reminds me of the sort of artifacts that are introduced on HDTV's by video processing...
[Galaxy S 4 Q&A, Help & Troubleshooting] D.O.C:
Lol u are absolutely correct, you get the point though ;)
[Galaxy S 4 Q&A, Help & Troubleshooting] shortie1987:
Haha I do, and I think you're right that a driver revision or some modification to the refresh rate could fix this. Even if there is some deeply embedded motion blurring or noise reduction going on, this could be the cause.

I dont think its to do with the pixel arrangement, although I'm no expert either! But with the pixels the size they are today, I think you would struggle to see the problem so clearly if this was the case.
[Galaxy S 4 Q&A, Help & Troubleshooting] D.O.C:
Yes, I was thinking about adjusting the GPU clock via kernel or init.d. But I am over speculating (if such thing even exists (errr ww financial crisis))

Let me try to get ahold of [MENTION=2617206]supercurio[/MENTION], [MENTION=289089]gokhanmoral[/MENTION] or anyone with more knowledge than me (or at least someone who knows better so they can give us their perspective about if this would really be a "faulty batch" or a side effect of samoled HD screens (even with this, I do prefer this pitch black over any non smudgeable less gray screen, but that is just me).
[Galaxy S 4 Q&A, Help & Troubleshooting] shortie1987:
I'm a big fan of Samsungs OLED screens too, but then I'm a big fan of plasma TV technology and its for mostly the same reasons. If the I9500 is suffering from the same issue its likely not a driver issue as such though, what with them using different GPUs...

Would be very interested to see what someone with more knowledge on these things thinks.

I'm also in the camp that its not going to cause me to want to send my phone back. sooner or later this thread will disappear, whether this gets fixed or not, and I'll forget about the whole thing, never to notice it again!
[Galaxy S 4 Q&A, Help & Troubleshooting] D.O.C:
yeah, same here....

Let me make a link of this thread in the general forum aswell, since its not really a question but a general query, that way we could get more users involved and try to get that unique screen video without smudges, then we could revolt and make Samsung go nuts :P

[MENTION=5238437]problems[/MENTION], do you mind if I change your thread titles to "GT i950x screen issue, please read", aswell as adding to the OP intructions for users to add its HW rev and firmware ver by dialing *#12580*369# to this thread.
[Galaxy S 4 Q&A, Help & Troubleshooting] Mittaa:
Somebody in this thread mentioned black being a bit reddish (not turned off) and no smudge issue. After flashing another firmware the reddish was gone (pixel turned off) but now he got smudge instead !

So yes - I think it could be something do with delay turning pixel on/off
[Galaxy S 4 Q&A, Help & Troubleshooting] ilabs:
Thats a good idea. Perhaps the solution can be found if we persist on it as more people get their phones and there are more to work with.
[Galaxy S 4 Q&A, Help & Troubleshooting] themissionimpossible:
From *#12580*369#

AP I9505XXUAMDF

CP I9505XXUAMDF

CSC I9505ITVAMD8

RF CAL 2013.04.19

HW REV. MP 0.900

But we should find a way to know which is the display manufacturer...
[Galaxy S 4 Q&A, Help & Troubleshooting] D.O.C:
Does your screen behave with "smears"?
[Galaxy S 4 Q&A, Help & Troubleshooting] themissionimpossible:
As I wrote before, I couldn't reproduce the problem in any way on my S4.
[Galaxy S 4 Q&A, Help & Troubleshooting] roguex:
If it helps mine is:

AP: I9505XXUAMDE

CP: I9505XXUAMDE

CSC: I9505OPSAMD6

RF cal: 2013.04.24

HW Rev: MP 0.900

And has smears!

Also to help people easily reproduce it.

Set the device to lowest brightness => this is important as very high brightness hides the "smear" somewhat.

Go to the settings menu, tap "more" => "About device" => "Status".

Now scroll up and down slowly and watch the text go purple and fade in and out! It should be grey and legible but it's not
[Galaxy S 4 Q&A, Help & Troubleshooting] D.O.C:
Oh.... ok, it would be very helpful if you could make a video of your screen while scrolling, not that I do not believe you, but to have a definitive proof so some of us could got to the hassle of exchanging the units without hesitation :)
[Galaxy S 4 Q&A, Help & Troubleshooting] themissionimpossible:
Here the video:

http://videobam.com/Trlqe

Brightness 15%

No pink smears/smudging, only the grey writings become slightly darker when scrolling
[Galaxy S 4 Q&A, Help & Troubleshooting] ilabs:
Samsung manufactures the display themselves. AMOLED screens is kinda their speciality.

BTW, the video you uploaded just keeps loading. Could you upload it elsewhere?
[Galaxy S 4 Q&A, Help & Troubleshooting] themissionimpossible:
Not at the moment, unfortunately.

But the video view counter is now at 24, so you should be able to see it after a little waiting.
[Galaxy S 4 Q&A, Help & Troubleshooting] D.O.C:
Thanks!

I will see it in a pc in a short while for greater detail, but watching it in mobile, do you see how those grey lines that divides the screen horizontally become less accentuated when scrolling?, that is exactly the behaviour I see as well on my screen. Big grey titles at settings are the ones that show the "smudge".
[Galaxy S 4 Q&A, Help & Troubleshooting] Vertron:
Do you mind posting a link to the post your referring to? I can't find it anywhere.
[Galaxy S 4 Q&A, Help & Troubleshooting] AndreiLux:
This has nothing to do with the screen itself, it's an issue of the screen controller. Solely hardware tied, or at least in terms of controller driver.
[Galaxy S 4 Q&A, Help & Troubleshooting] themissionimpossible:
Yes, the writings and the lines become slightly darker (probably less accentuated just as you say).

But I can't see any pink color.

I tested the same screen scrolling on my GS2 with JB 4.1.2 and the behavior is pretty similar.
[Galaxy S 4 Q&A, Help & Troubleshooting] Al Gore:
Guys as this thread is quite fast please post a separate thread or update OP when there are news or fixes.
[Galaxy S 4 Q&A, Help & Troubleshooting] D.O.C:
Not pink here either, its blueish/purple on grey while scrolling (that is why is more noticeable on big grey titles ;))

[MENTION=4167023]AndreiLux[/MENTION], thanks for the insight :), that would mean fixable (not necessarily easy though :P, but ill bet you could pull this one out :)
[Galaxy S 4 Q&A, Help & Troubleshooting] Zanr Zij:
I tested 3 S4 and all same.

I guest : the reason is adapt display. Samsung tried solve some Super Amoled problem by software.

Sent from my GT-N7100
[Galaxy S 4 Q&A, Help & Troubleshooting] bala_gamer:
I think that's the issue, with 0 brightness it will be more clear.

[MENTION=4167023]AndreiLux[/MENTION]

Can you explain it a bit more for us please?

Just as I suspected - so I guess it's cool and we can count on Andrei to fix it for us like he did with the black crush issue :cool:
[Galaxy S 4 Q&A, Help & Troubleshooting] themissionimpossible:
Honestly, I've not yet tested at 0% brightness, but surely I don't care what happens to the screen at 0% brightness, as I never use less then 20%, and at 15% I didn't notice any real problem.

So for me it's all right! ;)

Is anyone returning because of this issue?
[Galaxy S 4 Q&A, Help & Troubleshooting] Quasar83:
I am getting mine in a couple of days and I'm thinking of not picking it up at the post office because of this.

What do you guys think? Do you think I should get the package and test the phone, or should I just assume this problem is affecting every device out there and not clame the package from the post office?
[Galaxy S 4 Q&A, Help & Troubleshooting] inolvidable:
If that's the way the screen is I would keep it; besides there is always a possibility of fixing by software. If someone can confirm for sure this is due to faulty screens, I will return for sure

¡¡So say we all!! from my GT-I9505
[Galaxy S 4 Q&A, Help & Troubleshooting] topcat07:
I assume even after 14 days we can replacement on warranty if it's hardware not software
[Galaxy S 4 Q&A, Help & Troubleshooting] DanteSSS333:
Um, just to make this clear, the issue is mainly visible on the grey bars which separate the different topics of the settings menu. You can see it pretty clearly on my video: http://www.youtube.com/watch?v=iNwCuufJuLM

Could you repeat a video with grey bars moving in it? Thats the only way to really see it, though I can also see that your text and the lines between the settings behave just like they do on my S4.
[Galaxy S 4 Q&A, Help & Troubleshooting] winlinmac001:
AFAIK, the Note 2 still has the fewest AMOLED issues of any Galaxy phone; the Note 2 has the best AMOLED display to date; with a real RGB matrix. I am not at all surprised with what you all are experiencing with the S4. Pentile is crap. Black clipping is expected; so are lines and smears. Cheers. :good:

[HTC Rezound] wiredwrx:
I have explored the phone using ES File Explorer. But, I just can't seem to grasp the file structure.

There is an sdcard folder, sn SDcard0 and sdcard1. Some folders and their contents appear to be mirrored in other places. There are several sdcard folders, in various other places. Just confusing as heck to me.

Can someone please explain the file structure to me. What is the external card. What is the internal card? Why is there are internal card? Why are there multiples of the same folder. What does mnt mean?

Thanks for the help.
[HTC Rezound] bunchies:
This won't answer much but sdcard is the removable one and emmc is the internal storage. Idk why its there's short cuts everywhere, maybe its just faster access but it doesn't take up space

Are you trying to do something specific?
[HTC Rezound] GrayBoltWolf:
The external card is the Micro SD card you see when you take the back cover of your phone off.

The internal card is the 16 gb of internal storage that is part of the motherboard.

The internal card gives you more storage and is also where some system files are.

Multiples of the same folder? I dunno.

mnt is usually the "mount" folder in a linux OS (which Android is) and where drives and storage is mounted.
[HTC Rezound] bunchies:
actually the Removable sd card is the 16Gb one. not the internal
[HTC Rezound] feralicious:
The internal is 16gb and the phone comes with a 16gb for the external as well - it's partitioned though, so there's the "internal" and "phone" for the internal 16gb card, then "storage card" for the external if you look under storage in settings. My removable external is a 64gb. :highfive:
[HTC Rezound] bunchies:
Hmmm, I haven't upgraded mine yet but I only have 600mb left total Lol
[HTC Rezound] GrayBoltWolf:
The Rezound has 16 GB of internal memory and comes with a 16 GB micro SD card.
[HTC Rezound] bunchies:
I just found that out

I assumed because my micro SD said 16Gb and internal was partitioned at 10gb than I tested by taking out the micro SD card and than booting into twrp and used the file manager to see if sdcard was gone and it was but emmc was still present
[HTC Rezound] feralicious:
Well you can get a 64gb card for $100 less than I got mine for, well actually, for $55 more since mine was a xmas gift. ;)

Seriously, you can get a 64gb card for less than $60 on amazon.

Hi,

I have a sim-free XDA II which as it happens is on 02. How can I get rid of that User Interface though - I really hate it, and want to remove it?

Can anybody help please?

[MDA II, XDA II, 2060 General] Ryanmt:
goto ad remove programs and remove anything o2 related, then soft reset. Change the dialer skin then all your left with is the boot screens and the o2 logo on the case
[MDA II, XDA II, 2060 General] andyclap:
I'd recommend chaning the dialer skin back to the default before uninstalling o2 active; there are some images stored in dlls that are difficult to find, but can be changed via the phone skinning applet in o2 active.
[MDA II, XDA II, 2060 General] Shadamehr:
The correct order (IMHO that is), is as follows...

1 - Firstly, while you still have the Active interface, use the menu item on the navigation bar, I think it might be listed as 'view' to go in and change the dialler skin to the default one.

2 - Then soft reset.

3 - Next up, now go into File Explorer on either the phone, or via ActiveSync, and go to the Windows/Startup folder, and delete the shortcut for "Active"

4 - Reboot again, to get the phone to load without Active running.

5 - Go into Settings > System > Remove Programs, and remove the Active app, the V2R stff, and O2 Xmail if you never use it. You will get warnings that some files or folders still remain - no problem, this gets resolved later...

6 - Another soft reset.

7 - Now, go into File Explorer again, to the Windows Folder itself, and delete the folder for the V2R stuff.

8 - Change your Today theme to something better looking, do a re-boot, and voila...

If I have missed anything that I think of, I will come back and editt this post, but that's it for now...

EDIT - even if you change the dialler skin back to default before removing the O2 stuff, you will find a strange quirk with the talk/end button, whereby even with the default skin, after ending a call, the old flat red O2 style button will display.

This can be resolved by downloading the XDA Phone Skin Chooser application available from DesignLab (do a google), and then setting the skin to use (even though you might already be using it) to the Default Skin, and then resetting the device. This is the only way I have encountered, other than hard fiddling with hard to find .dll's, to get ALL the buttons to use the default skin, and thus have a proper 'pressed in' appearance when touched.

[MDA II, XDA II, 2060 General] z0mbi3:
Better than just uninstalling it?

Will removing it in this way stop all o2 related programs reinstalling after a hard reset?
[MDA II, XDA II, 2060 General] davidand1:
Not sure. I've never tried to uninstall everything.
[MDA II, XDA II, 2060 General] Shadamehr:
No, not by a long shot.

As the installation files etc, are stored in 'hidden' extended rom, and all a Hard Reset does is clear your phone, and then set about running and installing any files in the extended rom.

To remove it so that it is not installed after hard reset, is kind of achievable, but only if you know what you are doing.

You would have to use the Extended Rom Unlock tool on this site, to unhide and unlock your extended ROM, then you would have to remove any of the CAB install files from this folder for the O2 stuff you don't want (and its up to you to know what's what).

And then you would need to edit the config.txt file that 'calls' all of these installation routines, so that it no longer references any that you have deleted.

Then you could lock and hide the extended rom.

Thus, on a hard reset then, only the stuff you have left gets installed.

[One (M7) Q&A, Help & Troubleshooting] JRDroid:
Certainly it would be possible. The SGS4 and the Optimus G Pro both are vary similar to the One hardware wise and both have that feature. Now, if they will or not is an entirely different question that no one outside of HTC can answer.
[Droid Incredible Q&A, Help & Troubleshooting] Wallex:
Hello all, I am looking for an EASY way to root the Incredible. There has to be a better way than this stupid "downgrade this, flash that" bull that I am seeing everywhere. Do any of the one click root methods work anymore? Or can someone give me a guide written in legible ENGLISH (I.E NOT THIS: http://androidforums.com/incredible...ot-unlock-downgrade-achieve-s-off-htcdev.html)
[Droid Incredible Q&A, Help & Troubleshooting] tiny4579:
What is your HBOOT version? If it's 1.02 or higher that is the best way and only way I know of. Also in my opinion one click root methods teach you nothing and make troubleshooting difficult.
[Droid Incredible Q&A, Help & Troubleshooting] Wallex:
No interest in learning. HBOOT says 1.07.

Problem with guides like that: They aren't full guides, "i.e use adb devices to see if connected. If its not, install HTC Sync" guess what, HTC Sync didn't change a damn thing.
[Droid Incredible Q&A, Help & Troubleshooting] Pons:
Well, most people consider root a power, and with great power..... Anyways,this is a developer forum, aimed at developers. I don't have a problem teachinganyone anything (within the realm of my knowledge, of course), but I do have aproblem with those who want their hand held, and refuse to look on their own. Ican pretty much guarantee you, that if you don't learn anything, and wanteverything spelled out, that's all fine and dandy, till you have an issue. Orsomething else doesn't work right, and then you constantly ask questions on howto fix your phone when a little research and a little learning will preventmost of these issues in the first place.

/end rant.

Sorry about that. You're easiest bet is to use htcdev.com to unlock your bootloader, then flash a recovery through your now unlocked HBOOT, then flash aSuperuser.zip to gain root.
