Hi, has anyone noticed the screen flicker a little when watching videos? I don't notice it on every video but I have a video that is a little bright and the video takes place in the snow and ice. I can see the screen flicker slightly during the whole video. At first I thought it might be my micro sd card so I tried youtube and some videos do it there also. Only seems noticeable on bright videos.
Also, all of the videos I watch stutter a little. Doesn't matter if its videos I have stored on micro sd or youtube. Anyone else have this?
Really want to keep the tab because around me they are hard to come by so returning it will suck. But everytime I think I might just keep it I find something else wrong:crying:
So far dust between gorrila glass and digitizer, screen creeking in left corner, burning smell from speaker and screen flicker and stuttering videos.
Anyway, hope no one else is dealing with this
Also if no one minds could you go to this link on your tab and see if this video has screen flicker for you guys too? I watched on my pc and I see no flickering.

Some refer to it as a problem due to "Didimm".

? What do you mean? You mean the dimmer? If so I was thinking that as well. Guess I do need to return it?
Thanks for getting back to me
Goggle "didimm" it is a feature from nvidia. Many notice it, some don't.
I for myself rarely see it. And if it doesn't matter for me.
Maybe compare it to a device in store to see if yours is defective?
Hmm, that article says that your eyes would never be able to see the difference - well, guess what - almost everyone can see it! I assumed it was a "dynamic contrast" - just like some TV's do, but whatever it is, it *is* noticeable and it *is* very annoying at times. At least give us the option to disable it when needed (like when watching videos etc). The problem is that it seems to do it in stages, and like I said, there are *many* folks that find it very annoying.

Dynamic contrast is even worse with anime. You don't know the feels I know.
perhaps this can help:

EDIT: It works!
just use the terminal emulator app (or adb shell) and do
Code:

Bam! no autodim until the next reboot

Great find! I too can confirm it works! Haven't noticed any degradation in screen quality/contrast either (although I guess it will effect battery life). Regardless, at least know we know we have the option to disable/enable as needed!
Thanks alot!
EDIT: What's strange (in my mind), is that if this feature is only for battery-saving, why wouldn't it be disabled while on AC power? That would be great if it would automatically disable this "feature" while on AC power, since the only goal is conserve power...

Ok so I am not going crazy and my old eyes aren't playing tricks on me. Well not really old (32).
So it seems that even if I return it for a new one that this problem will be on that one as well?
So I wonder if some have it worse than others? Maybe I will still get a new one. I just fear that I will get a new one and it will have even more problems than the one I have now
EDIT: After going to link provided it seems things happen "after" watching a video. Where as my problem is during videos. And not all videos it seems. The link I posted to youtube does it bad on my device. Plus am unsure about rooting because I may need to return it to bestbuy and i dont want the geeksquad trolling thru the device looking to see if i did anything to it like rooting

Hey lardo. Thanks. Im thinking the same thing. Just sucks because bestbuy that close to me said it could be months before they get one in even if they order it for me.

I would *not* return it for this! It happens on all TF700's (the original link is for the Nexus 7, which behaves differently, I believe).
Again, it's not a flaw - it's by design. This setting will allow you to disable/enable it though (I would hope that Asus also adds a toggle for this in future firmwares).
But returning it for another is not going to help and you may end up with a unit that has a real problem...

The flickering: I would not return it for that. I'm sure all the tf700s flicker just the same.
The stinky speaker: I would wait for it to fail first, then RMA it.
The dust trapped under the screen: Exchange it even if its just one spec. I exchanged my tf300 for the same reason, and my tf700 screen is flawless. The screen is the most expensive and prominant part, it should be flawless.
A couple months seems long. my exchange took around four days. I would reccomend taking it in for exchange and seeing what their estimate for the date would be. If its too long, you can always back out of exchanging it. You could also give RMAing it a shot, that will take weeks (which is better than months)
Rest assured the fix I linked to does work. I even used Script mananger, and the scripts provided on that page to make a desktop widget to turn it on and off. Dont worry about rooting. Flashing the firmware from asus's website will unroot it without a trace, then do a factory reset and you're good to go.:good:

Hey jtrosky. I agree exchanging just for that reason may be silly, but I have other issues as well ( like video stutter, dirt under screen , creeking screen which I see others talking about so probably happens to them all, and burning smell from speaker. I do thank you for your respnse though. Oh and the screen problem I am talking about in this thread I did not notice on my Transformer Tf300 which I returned for the Tf700

Well returned my tab today. Getting my new one on thursday. Hopefully all will be ok. We will see.
Also gonna root the new one when I get it and do the mentioned tweak from those in this thread. Thanks guys for checking into this for me:laugh:
Ok! WTF! I just got my new Tab and so far , It had white and red crust on the back of it. The power button is really raised up. And Mother [email protected]#$ it also has the burning speaker smell . I mean I have to put my nose to it but come on. Gonna check it out some more and see how it goes. I really hope this one is a keeper but not looking that way.
Also thanks again for those that posted a link about the dimmer issue
Hmm. All electronics smell like they're burning when they're new. Sure it's not just that new tablet smell? Anyway hope this one works out for you.

Thanks rightonred! Yeah I know. I'm gonna give it some time. Was really just mad about the crusty stuff on the back of it. Thought I would come to my home away from (XDA) and share my sadness. But yeah, I'm gonna give it awhile. So far the only other thing I have noticed besides the crust,wonky power button, is a little light bleed and haptic feedback is really really soft.
I have the Galaxy Tab 2 7.0, rooted with 4.0.4, and have not had any problems with it for the most part.
I recently downloaded Sketchbook Express to see how well the tablet could handle drawing. It handles it very well with one exception: the closer you get to drawing at a 45* angle, the more wavy the lines get. If I quickly swipe in that direction, it straightens out, but the slower I go, the more pronounced the waves or zig zags get. This happens using any of my fingers, the $20 Rocketfish stylus, and the $30 Wacom Bamboo stylus. All attempted on a freshly cleaned screen. I've also tried different apps with the same result. This guy had the same issue, as have others from what research I could pull up, but outside of unhelpful answers of "it's your stylus" (it's not), they all seem to have given up on getting help.
I've tried these apps on my friend's Evo 4G 3D, running Android 4.0.3, and had the same issue. I then tried on my rooted Xperia Play running Android 2.3.3 Gingerbread, and did not have this issue. I'm not entirely convinced it's an OS version that's making the difference, but I'm not able to find much information about the screens these devices use outside of "capacitive touch". I did learn that these screens use the corners to determine the location of input being received, so maybe moving directly in the direction of a corner is causing it to mess up?
Long story short, my questions are thus: is there any way to fix, calibrate, or compensate for this issue? Is it the screen, a hardware issue, or something else? Is there anything I can do?
Thanks for your time.

The problem is the digitizer. It's cheap. I think all of the g tabs have this issue. Mine is terrible drawing diagonal lines and even scrolling in landscape mode is choppy. Only way around it from what I can tell is to apply more finger surface area. That seems to fix it. But since you're using a stylus that's not possible. If you find a solution to calibrate the digitizer, please let me know!
I have the same exact problem and the same exact request. There must be some option to increase sensitivity to at least minimize this effect. It's the only flaw I can find on this otherwise wonderful device.
And honestly, for the prize it cost, I would expect this not to exist. But... I have it now and would like to be able to use it in it's full extent and power.
dammit
Nice to know I'm not the only one who notice that, but it's crazy how my finger seems preciser than my pen and even more, that in my Galaxy S the pen works perfectly. I was so happy to use some drawing apps on the tab but when I tried...
I tried in my Tab 7 2, then I'll try on my uncle's 10.1 just to check.
hello all,
just to report the same issue. i have same problem with my samsung galaxy tab 2 7" like you all here. i get this problem since the first time i bought it (about a month ago). drawing the lines and reading in landscape mode is choppy :crying: same as MrHyde03 said. i have been tested my cousin's tablet to draw diagonal line for comparison, he has galaxy tab p1000. and the line result i get, though his tab has wavy line too, but mine has more wavy line than his tablet. i didn't noticed his tablet has so wavy line, just a little. i did it with my finger.
i hope this issue can be fixed later.
could be a solution
I don't know if it's just for marketing or what, but maybe the original Samsung stylus is better for these screens.
I wish someone could certify this...

Hi guys, I have the same problem. Horrible response when i draw with a (cheap) stylus and perfect when i do it with my fingers. Has anyone tried adonit jot pro or Dagi ??? Maybe they increase the contact area and it solves the problem. If so, please tell us!!!
Thanks for reading and waiting for a solution.
I know this is an old post, but I can't just abandon my own thread! I've done quite a bit of research on this since making this post, and sadly, it's the way the screen is. Strange that my Xperia Play and Galaxy S3 phones can do this, but the Tab 2 was given such a cheap screen. I ended up selling it and putting the money towards a Note 10.1 with S-pen, which works as I would expect it to.
So everyone was alright with my tab. the software was a little buggy with jellybean but nothing i couldnt live with. then one night after i finished charging it i look at the charger and see the picture i am attaching. i dont know how this happened. that part always clicked when i pressed it and now it doesnt but it looks like someone dropped it. i contacted asus and i sent pictures and they are starting an RMA. but should i do it and have my tab gone for 3 weeks and maybe it wont be fixed and i might have to pay for it.i told them i was having random reboots and stuff in hopes they would replace it and send me a new one. are my dreams far fetched?
I mean it isnt that bad but its ugly and not my fault. do you think they will fix it or replace it and do you think its worth the 3 weeks without it?
That happened to my wife's tablet, I thought it was due to the loose screen in that area and then docking it. I had her send it back to Amazon at about 3 weeks old and got a new one. I told her to be more careful when docking.
This happened to my wife's tab also, just bent it back. Does not sit well with me that it is so easy to bend but even if you return it, this will likely happen again.
You cn bend it back to almost normal as long as there is no crease. If you have a hobby hammer that the head is made out of silicone, you can tap it back to perfect, just be careful not to hit the screen of hit it hard, just do small taps until your satisfied. It happens usually when docking or undocking.
You can also use the black cap that covers the charging port by placing it above the bump and press down with light pressure until it returns to its normal position. This happened to me once with my Infinity. I wasn't paying attention to where the cord was and I ended up tripping on it:\ When I had the Prime it seemed easier to bend, less firm/Sterdy vs the Infinity. Waste of time RMAing it.

You might want to delete/modify the pics that contain your complete serial #. That is something that you should keep to yourself - see the infamous ASUS device tracker thread for an example why: http://forum.xda-developers.com/showthread.php?t=1833442

I don't understand how you can say it's not your fault. It's certainly not the fault of Asus. Of course they would fix or replace it but it would be at your own cost. I don't see why Asus should cover the cost of putting it right?
Don't get me wrong, I would hate this to have happened to my tablet, but I also wouldn't expect to pass the cost on to someone else (which I believe you are implying) due to my carelessness.
Live with it, repair it yourself or pay to have it fixed for you.
Odd. My port is actually bent the OPPOSITE way haha. I just bent it back. I don't think it's worth the three weeks + your hard-earned money. :laugh:
This happened on my Prime. It is caused by pushing the power connector in at an angle and not being careful or once it is in, allowing something to rest on the connector pushing the frame up.
It is easy to fix yourself and you can push the metal back down with your finger. Best way is to get something made of rubber or softer plastic and reshape it back to normal yourself.
I bought this tablet off Amazon's Warehouse Deals. It came to me dinged and scratched up, but operable. I noticed the touch screen was a little off and would report false touches occasionally, but I didn't think it was anything to worry about. Like a kid in a candy store, I raced to get a new ROM so I could optimize this thing. In the process I unlocked the bootloader, rooted and installed PACman ROM. Ghost touches disappeared--gone for like 3 whole days. I'm ecstatic, and falling madly in love with this tablet. Then I notice the ghost touches coming back after the 5th day I have had it. Now its showing about 3 ghost touches almost constantly in one vertical line (in landscape) on the right side of the screen. Pretty much totally inoperable. I have scoured all ends of google, and most of the time it spits me out here, searching thread after thread of nothing but "RMA it". My questions are:
Is there any fix to this besides shelling out money for a new digitizer? Is that the general consensus that the digitizer is the root of the problem? I know I'm able to return the product, but does anyone know if Amazon is going to give me grief over an unlocked product that was a scratch-and-dent deal anyway? Any way I can re-lock the device? I've seen multiple threads with replies saying "lol didn't you read the blah blah? no way bro", but these were posted a couple months ago. Maybe something new has come up. I guess I just feel sorta rooked because I bought a defective piece of hardware, and now I can't get a refund just because I modified the software.

Same thing happened to my brother's tf300t. He returned it as defective, but I guess you could replace the digitizer. As far as I saw, it was a hardware problem, so it requires a hardware fix. Sorry

I got a similar situation in the last two weeks. The problem I have is that my TF300T is keeping rebooting by itself. I've googled it and people say most likely it's a hardware issue. I am trying to find a way to see if the device can be reset to factory condition so that I can return it for repair. Looks like we are on a same boat. Hopefully I can find a way to do so.
Just an update on my issue, in case anyone else stumbles across this particular problem. So far I have gone almost a week with no ghost touches. I popped off the back of the device (three guitar picks did the trick), and disconnected the digitizer ribbon cables and reseated them. Problem vanished. My best guess is that the keyboard dock puts odd pressure on the device. That mixed with rough handling is bound to cause some problems.

It could be the power button is jammed? I know mine is really touchy (all I do is tap it with my stylus and screen turns on/off. Good luck!

Thank you. I just got mine from Groupon as refurbed.. (they did a ****ty job, apparently) Ghost issue about 2 days after getting it out of the box. By then already unlocked and flashed CWM.. sigh.
I'll try your fix tonight. Any chance there is an image of the right connector/ribbon?
Hopefully the image quality isnt too bad. I took an exacto knife and gently pried up the black foam squares, set them aside and worked my magic. Hope this helps. Just be careful with the ribbon cable (duh). Hope this helps!

Did this today.. So far, 20 mins on it, and no issues. Typically took about 5-7 mins before. So, crossing my fingers this is gone.
THANK YOU! I can go back to enjoying my tablet
Im in the same boat with this Ghost Touches Issues, and its getting worse, sometimes im working at college and this Ghost appears and the tablet gets almost unusable, Only the Keyboard Dock saves me.
Please if you can give me more detailed instructions i think i would be brave enought to do this surgery to my tf300t, merry christmas!

i just noticed that when having a ghost touches attack, if i put pressure con the tablet, lime trying to bend it, the touches vanish.
I also have the ghost touches but it seems to only happen when the screen is dirty. As soon as I clean it off, they go away. Would a good screen protector help with that? I may go ahead and try taking off the back and messing with it.

I thought mine was fixed, but doesnt seem to be. I technically didnt remove the connectors.. I was nervous, they are WAY fragile. I simply unlocked and pressed firmly on them to attempt to reseat them..
Problem seemed to go away until I used Chrome. Chrome is what seems to trigger odd behaviors for me. I may try another browser and see if it still happens.
I've been dealing with this off and on for about 8 months; asus HAS to be aware of it as my tab has been back twice for this issue (out of warranty now) and I take advantage of their complaint form every month or so.
Here's what I've been working off of (based on personal experience/experimentation):
Re-seating the cables might help for a day or less, but isn't a permanent fix. I even went as far as strategic pieces of tape to hold the flex cables in place and tape across the connectors to encourage them to stay closed.
The first time I popped the back off the larger of the three flexes (with the silver wrap) had partially worked out of the connector on the driver board. Re-seated it and problem disappeared for about a day.
The large copper heat spreader was basically spot contacting the CPU and really wasn't touching the smaller ancillary chips (unit had been running warm for a few months, thought that might make things wonky). I pressed heat shield back down to ensure adhesion, and slightly molded the copper around each chip. Ghost touch gone for two days, unit way cooler running than before.
Here's the interesting one to me. Tonight I noticed that even just hovering my finger close to the screen I can get the 'touch dot' to show; this got me thinking about static. I held the tab in a way that at least one finger of one hand was touching the screen, like towards an edge (out of the active area) while using the other hand to touch the screen. Seemed like one hand was grounding the screen, like a charge couldn't dissipate from the surface.
Isn't this a "capacitive touch' screen? Could it be a matter of grounding?
I too purchased this tablet and dock from Groupon about 4 weeks ago or so as a manufacture refurb. My tablet does the same thing. After about an hour or so use most of the time it starts randomly acting like the screen is being touched. And it appears to only be in the upper right corner area (kinda where the lock screen pattern show up when you unlock it) in landscape mode. Sometimes it may take a little longer of use before it happens. It happens regardless if the dock is plugged in or not. I have figured that if I lock the screen and wait a few seconds and then unlock it. The ghost touches are gone for a while. I first began thinking it may have been a OS issue and hough about rooting and putting a custom rom on it. But from what I have seen on the web it doesnt seem to matter whether its rooted or not. So should I RMA it back or has any one had permenant luck with reseating the cable?
Thanks

I'd try reseating the ribbons. I kind of doubt it would solve the problem since it's a refurbished with a latent defect. Bad ribbons would strike at random but do not wait for a while before acting up. Look at the glass surface under a magnifying glass and bright light. Hairline cracks cause this after the tab heats up, but you can't always detect them. RMA would be the safe option unless you're really pressed for time.
Ghost touches are back. Noticed I had alot of them when my storage was full. Used a previous recovery (same ROM, just earlier date with less junk installed) and it cut down the frequency of them happening. This is so weird.
I had those ghost touches when 4.2 roms started (CM and AOKP and all of the rest of them. Then someone, I don't remember who had compiled rom with decreased touchscreen sensitivity and ghosting was gone. I think they started with PAC or AOKP, I really don't remember.
Then I went to 4.3 and 4.4 roms and I didn't have one single ghost touch since then. I do noticed sometimes when I hover finger over screen it is registered as touch, but ghosting by itself didn't occur on those roms.
one cent fix
I have an ugly, but effective solution working on my pad right now. It has been in place for about three or four months.
Holding in landscape mode, pulled the bottom left corner back slightly and inserted a penny between the back and the lcd. This put enough torque on the screen to kill all of the ghost touches and it still fits into the keyboard dock. There is an ugly gap where the penny is, but it is now fully functional.
Hope this helps some of you
My galaxy tab 2 recently started having a yellow flicker when I pick it up or move it. Can't find anyone else with my problem. I contacted Samsung and they told me to do a factory reset. I did and it didn't work. Any ideas? I can fix it if I have to and its not to expensive. Or if the repair is cheap I would rather someone else work on it. I keep it in a belkin case so it is protected. The only thing is I bring it to school in my backpack but it should be protected in their. I managed to get a picture with my s4 of it.

if you are sure it did not fell on ground or have any other damage then try to again flash stock rom and even if problem persists it means that the problem is with screen { hardware]
