[Q] Problem Drawing Straight - Is my tab bad?

I recently purchased a Sprint Samsung Galaxy Tab 7 and whenever I try to draw anything other than a horizontal or vertical line it is very wavy. It makes using a handwritten note taking app that works fine on my Viewsonic G Tablet almost unusable on the Sansung GTab. Can any of you draw angled lines reasonable straight or do I possibly have a bad tablet? If I try to draw a line at a 45 deg angle it is extremely wavy regardless of how careful I am in trying to make it straight. It does this on various programs I've tried. Attached is an example from 'Note Everything'.

Can't somebody tell me if their Tab behaves the same or differently than mine? I guess I may have to make the trip to a store to see if a demo unit does the same thing as mine.

Hi,
You are not alone with this problem. This is the good news but unfortuately I bad news is there is no known solution. Make a search with screen shaking you will find more people complaining about this.
Cheers

Thanks for your response. That is unfortunate. One of the main reasons I purchased the Galaxy Tab was to take notes with a stylus using TabNotes and the screen doesn't work well with either finger or stylus. It works very well on my Viewsonic G Tablet but the 10.1" screen is a little to big and the portrait viewing angles are really bad. Thanks for the tip on searching for 'screen shaking', I tried a bunch of other terms and couldn't find anything so I'll give that a try.

Your sample looks a little better than mine. I think I will try to find a store in my area that has a demo unit so I can do a side by side comparison.
Have you had good success using your tab for note taking?

No. I tried like 7 different apps, but no one worked like I hoped. I even tried two different styli but still, I find swype to be easier and faster.
I'm running Overcome Gold 2.0 by the way, may be that's why it is a little bit different.

I just got my refurb sprint tab from woot. I have the same problem. Bummer.

Adding ffc to nexus one, suggestions?

Well I have some extra time and money on my hands, and I was wondering if this would be possible in any way? If I got the same exact camera for the nexus one, is there any room or any way I could add it in? I was thinking of cramming it in there, and having both cameras connected to a switch/button I could have coming out the top of the phone? So I could make it where if the switch/button is pressed it would change which camera being used. I've looked at teardowns and I can't tell if this would be possible or not, nor do I even know if its technically possible or not because I don't know if the camera connections could be set up this way. Anyone tried this before?/Suggestions?/Discussion?

hi
i dont know how to help you but i am very sure, that there was a hardware mod where someone added a front facing camera to a phone that didn`t have one.
i think it was even featured on the xda frontpage and it might have been a samsung phone.
you might wanna look that one up and maybe it helps you
good luck with your Project!

Yeah, I remember seeing that on Engadget, it was a Galaxy S variant if I remember correctly.

Yeah I looked into that a little but this is a little bit of a different situation, considering those phones had an actual slot available for a ffc.

True, what about the proximity and light sensors in the to left corner of the Bezel? Do you use auto brightness?

I could easily go without that lol but I guess I'm wondering more about being able to attach two nexus one cameras to a switch, what parts would I use and is it possible? I don't know anything about that

Screen Flicker - Does anyone NOT have this?

So I'm debating RMA's the N7 I have with Google Play. I have a slight screen raise (this doesn't bother me too much) as well as screen flicker that I notice in low lighting situations (mostly in chrome and maps).
Does anyone NOT have screen flicker? Or is this a software issue?

Hey, I believe the screen flicker is due to the auto brightness function of the device.
I personally don't like auto brightness at all, try turning it off in the brightness menu and see if you still get that.
I see the flicker quite often with devices having that function turned on.

Hmmmm well I guess the only thing I have to compare it to is my iPhone 4 which doesn't do this.

My eyes are usually sensitive enough to be annoyed by screen flicker in any respect. Certainly with overhead CFL lighting.
My 16GB Nexus 7 (2 days in my posession now) doe snot exhibit any sort of screen flicker whatsoever. This is in comparison side by side with my HTC Desire HD which also does not flicker.
The display actually has a very high quality feeling which I like.

Thanks for the feedback. So even in low lighting conditions, with auto brightness set to on, and scrolling around in chrome / maps, you screen never flickers or sort of rapidly dims?

I've noticed it. Only on white web pages or books. Very slight. I had two HTC One Xs that both had it. Its a Tegra issue and doubt we will see a fix. Gutted.
Its not the whole screen. Noticeable around text especially. Some weird refresh prob. Left side of my screen is also slightly raised. Not happy.

I definitely get it on the whole screen, maybe for a second or 2. Might do it 2-3 times per day at most.

double post - deleted

Happened to me, I just turned the auto brightness off and t was fine. Try it, it works.

I keep auto brightness disabled and I haven't noticed the flicker that I can remember but tonight I'll try to reproduce and check it both ways.
I disable auto brightness and use this app which is actually a widget. It allows you to UAW any edge on the screen as an invisible or barely visible slider for brightness. It allows for incremental 1% changes on a slider instead of the typical button/toggle widget and its always enabled if you set it that way which allows on the go ease of use no matter what app or screen is open.
Its helped me attain amazing battery life and always have quick access for setting it just right.

No flicker......no raised screen.

No flicker here. Although I agree with disabling auto brightness, not a fan of the effect that can sometime have.

I understand that - I'm trying to gauge whether or not it affects ALL N7's, or is a defect.
Google Play is shipping me a replacement N7 to address the screen raise on my current one, and I want to make sure the replacement is 100% A-OK.

Make a poll if you're trying to do that.... But yes, I see flicker too, but only at very low backlight levels and seems to be when wifi is active. I haven't tested to see if it's just wifi, or wifi causing other things (disk activity, etc), but this is the general consensus so far in the other thread.

Little black pixels on the photo/sensor

So I just noticed that when I launch the camera I see a little black spot.. And it's visible on every photo in the same place.
It's not about the screen, the screen is clean without any defects.
It's also not about the camera glass.
What is it? Did anybody experience such a thing?!

Is it in sameplace when raking a photo in landscape and portrait?

It's a defect in the image sensor. I had the same thing on a Samdung device on the FFC.

No, it won't typically grow. It's usually a manufacturing defect.

In my case, the sensor had three of these dots. I've had the device for a couple of years and taken shots with it countless times. No changes noted. It's now my wife's phone. She doesn't even notice it, but it did piss me off when I noticed it.
The good news is it won't grow, and not that it helps you feel any better, but it's pretty easy to remove those type of dots in images if you need to.

If the dot is in the same place it could be software related if it changes positions a little it could be hardware sensor

I don't think so. The hardware doesn't change, so the image sensor defect (typically seen as black dots) will always be in the same place, regardless of orientation.
If it were software related, then software would change it, but it doesn't. In my case, though it was a Samdung device, I had the issue before and after all camera software and firmware updates.
Here's a thread on this topic about the Z specifically.

Yes true that. It doesn't change the location so it definitely looks like a hardware fault....

Im aware of that threat butt bearrrr with me for a minute and here me out...
What iff..you mesure out the dot from the side in portrait and then in landscape.....sience will tell you cause landscape is wider that the dot wil be in a different place because of the wideness off the picture...true? Thus its hardware matic fault in my opinion...if it stays in one spot my guess is it wil be a rendering malfunction......why im i saying this......
Im having 1 little dot in portrait but NON in landscape can someone explain me that please?
Sorry cant prove it by pictures because my phone ia in the shop for a screen replacement
Edit: would you mind trying to turn of be2 and hdr and auto mode,im curious if it helps in anyway

Permanent red tint on screen

Hey guys,
I started noticing bit of red tint on lower half of the screen.
I am aware viewing angle make difference, but no matter which orientation/angle I look from it is still there.
Anyone else having similar issue?
Also, if this is a defect, is this the kind that retailer usually replace for consumer?
It is giving me headache looking at the screen for a prolonged period even though the tint is not severe.

Its very, very slight on mine. Nothing that would make me consider returning it though.

Also, screen tint shift based on angle is a lot more frequent than my s3 (i9300). I tilt note4 by even 5deg and I see colour shift already, but nothing like that on s3.
Can someone confirm this please.
Thank you.

Yes, my phone does this. However I've checked a lot of shop display units and have noticed many are better and some are worse than mine. The sad fact is that there seems to be a bit of a screen lottery going on and it's luck whether you get a good screen or a bad one.

You can try it. If they have a display unit that is obviously better than your current one and they can see that. Problem is you might end up with a replacement that is just as bad or worse!

Thats been the case since the Galaxy Note 2, even my note 3 has a slight reddish tint on the top part of the screen.. most if not all the units ive seen either has a red tint or a more warmer color tone at a certain part of the screen. People have accepted this as a norm.

Yeah funny it is a norm for Note series when it is not for S series when both using same display technology
Sent from my GT-I9300 using XDA Free mobile app

Agree. My old s5 was much better with colour shift and tinting. As are the new tab s tablets. I'm disappointed with the note 4 screen.

Have you tried setting the display to photo mode?
I am still wondering if we talk about the same phone, my Note 4 has no red tint and no color shift at all, no matter how much I turn the phone.
Also looking at a totally white/red/yellow picture, I can't find any part of the screen that is warmer. Some people also reported that greys look terrible, I can't comfirm that for my display.
Coming from the Nexus 5, this display looks so much better in all aspects, I am still stunned after using the phone for 3 days now.

There seems to be quite a disparity between phones. Some are good, some are bad. That tends to be why people are having different experiences.

It was the norm for the S series up until the S4 came out. The S4 was the first Samsung screen since the Note 2 that had a very nice and even screen.
S1, S2, S3, Note 1, Note 3 all suffer from poor screen uniformity. Guess you can add the Note 4 to that too.
This worries me as I'm planning on skipping the Note 4 for the Nexus 6. Samsung will already be giving Motorola last years Amoled tech, and stretched across the bigger screen the unevenness will be even more obvious.
Especially now that Android Lollipop will be mostly light grey everywhere! Amoled's worst nightmare.

red tint?
What red tint, is this when the screen is on? off? I haven't noticed any red tint but now I'm worried...

Wow, if you do not notice it - do not find a reason to notice it. Be happy with your device.

My display is a very slightly more blueish/pinkish towards the top half, specifically the top right. It's only noticeable on white content. It's subtle enough that I won't go through the hassle of getting a replacement especially since the replacement could be even worse... At least my display has been brightness and no banding or anything. Overall though, this display is simply phenomenal. Hopefully these slight display issues will improve as time goes on, although the screen on my S4 was very uniform, doesn't even come close to the performance of the Note 4 screen though.

Seems like the problems are much less pronounced that the typical uneven backlight of LCD?
