Man that sucks to hear I know this has nothing to do with tab but I've noticed psp and even some tvs have a pixle fixed and all it does is flashes through the 3 basic colors rapidly and it normaly fixes it

trying jscreenfix now. so far no luck

bump still not fixed

A dead pixel is usually just that, dead. It affects a small percentage of lcds and the only real fix is to get a new screen. So either send it off to get a replacement screen fitted or a cheaper alternative is to replace it yourself.

Typically, defect of dead pixels (up to 5) is acceptable for a screen size of 7 inch, it is not subjected to manufacturer's warranty, same as for a laptop. It is under disclaimer notes. This is due to the properties of glass during manufacturing process.
I am not sure if Samsung will honour any wty claims on this?

If it's black, then it's probably dead and you can't fix it.
If it's a colour, then it's just stuck and (as you've tried) the jflasher app sometimes seems to work, you might need to leave it running for several hours though.
The early PSPs were terribly prone to stuck pixels, but they used very poor quality LCDs (hence the awful refresh rates), thankfully I've not had any recent devices (2 large TVs, tablet, phone etc) with any stuck pixels. I had an iMac for a while which had 3 stuck pixels, jflasher fixed one of them but the other 2 were stuck, one was about 2-inches to the right of dead centre and bright pink, so it was quite noticable.

No, its stuck. Have tried running jscreenfix with no luck. any other ideas or am i best calling tesco again? I have also tried a pixel massage (Worked on my laptop after i got it back from having a new screen fitted (Glossy instead of the original antiglare - WITHOUT MY PERMISSION!!) with 5 stuck pixels)

Massage won't work on the tab, the glass is too thick.

Thought so.

Oh ASUS...

So my first transformer was awesome except for the touchscreen that was unresponsive on a whole line across the tablet, the minimal light bleed, and the unbalanced speakers. I decided to rma it with ASUS and sent it back.
I just got it back today. The shipping paper shows a new part for a screen (I'm guessing.. 90R-OK061L20000Y). I immediately installed a multi touch and paint app to check the screen only to find an almost identical unresponsive section of the screen (on both it was unresponsive to the lightest of touch only. Heavy touches still registered.)
My question to my fellow Transformer owners is should I RMA again? Maybe switch to the galaxy tab? Hope its software related and wait for a fix? Our just ignore it?
Anyone else have this problem?
Sent from my Nexus One using XDA App

The Transformer is nice especially with dock if all works well, mine does, but if that were me I'd be unloading it and getting a Galaxy 10.1.

I just tested mine with the same paint program. I colored the whole screen with 1 finger and everything seems to be in order. Funny how that program registers 7 finger multitouch but 8 will cause a FC.
Anyway. I would RMA it again. This time stating that the problem wasn't fixed. Maybe put a bunch of post-it notes with arrows all pointing to the spot there it is whacked.

If this really is an issue only with "lightest of touch" I think you would be better off selling the unit. Touch screens often have areas that require more or less contact. The fact that they replaced the screen or digitizer and it does not meet your expectations suggests the settings they are using will not meet your expectations as to the amount of contact required.

Just a quick question, wherever you guys bought your transformer, did anyone buy a warranty through the retailer? Personally I work a BestBuy, so a 1 year with damage warranty was dirt cheap for me, so i bought it, normally I dont get the plans bc I treat my gadgets like angels, but with a 10 inch screen thats only protected by glass I thought I should, especially with all the defects from ASUS going around (although mines working perfect!).

Well as an example when trying to launch an app along the line a hard press is required

Could it be a problem with your fingers? Seems strange you have had problems with 2 lol

Are you saying my fingers is brokeded!?!
Sent from my Nexus One using XDA App

he's saying you touched it wrong

well I would insist on a replacement if the issue is still there. You would of thought they would of tested this before it was returned to you.
I would of thought it would be other hardware other than the screen that is defective and they have simply replaced the incorrect part.

I called asus again and they game another rma. They paid for doing too, that's nice. hoping for a fix though.

[Q] Where's the proximity sensor?

Hello, just one simple question: where's proximity sensor in the A500/A501? I have the Acer flip case but if I close it the screen stays on... Should I enable it somewhere in the settings?

Are you referring to the ambient light sensor? If so, its on the top left bezel, between the volume rocker and the rotation lock. If you look at the black glass there in bright light, you will see a small dark spot, that is the sensor.
As for a setting, the screen will dim based on ambient light levels, not shut off. The setting for it is located by tapping the clock, then the settings button, then the word "auto" next to the brightness slider.
Was this post helpful? If so give thanks

The correct answer is a question... What proximity sensor?

this is driving me nut
the Acer case will always partially cover this one and the dispaly will fluctuate the brightness in random... ;(
pushing A500 firmly into the case solves for a while before happening again - think I need new case...

Based upon this site that contains the tech specs, http://gadgetian.com/10395/acer-iconia-tab-a501-specs-price, the A501 should contain a "proximity sensor to turn it on or off". Please note that if you google for "Acer iconia tab proximity sensor" you will get a number of results, so I doubt that it's just a mistake of one site.
So there's no way to turn the screen off while the tab is properly fitted in its sleeve?

Couldnt the light sensor be used as a proximity sensor? With software I mean.

I have checked my tablet from top to bottom and even made some sensor test to make sure that everything is working and I never saw a listing for a proximity sensor so I'm sure that we don't have one (or a barometer... that was also one of the things that was possible to test ).
@cd85233: Probably yes but I wonder what kind of impact it would have on the battery.

there is no proximity sensor on the A500 nor A501. refered to spec sheet and hardware implementation... unless they changed it since last release.
who told you so ?

Guys, there's an app called tasker. You can use that to tell the tablet to lock up when it receives less than 3 or so % light reading from the light sensor. It works great on the gtab. Still waiting for the case for my iconia to test it out.

still an ambient light sensor, not proximity sensor. As for if it could bbe used as one by software I'm not sure. For the case, look up roocases for the acer iconia on amazon. I have the folio multi-angle black n love it!

This works 100%. Just did it on my Iconia.
Set the trigger to be light between 0 and 5% and the action to be "Display"->System lock.
Let me know if you guys need help but this is easy and works AMAZINGLY. I don't know if more battery use occurs to poll the sensor though. Will report if I see it in the battery usage.

Just because someone calls it that doesn't make them right.
Go ask a PC repairer how any times a customer has asked to have their hard drive partition fixed when what the customer means is something completely different. Meaning people often use what they think is technical jargon to imply knowledge they don't actually possess

Ok, no need to attack Just asking, and just telling you from where my speculation came from Various sites lists it in the tech specs so I was trying to understand whether I have a faulty sensor or not. End of the story!

I get it, now you know n its kinda like how one off the wall chinese tablet has a "gravity sensor". Is it an accelerometer? Gyroscope? Our does it merely sense the presence of gravity? Will the device go haywire if used in outer space? Who knows! Lol tech specs can be painfully vague and inaccurate. Especially on a company who can't even figure out to name the source code for their kernel something that doesn't make it look like a help file, THEN place it in the documentation portion of the site, good job Acer! Point being I get the confusion

Smart Cover App

So I found out the hard way that the Tab 2 10.1 doesn't come with a proximity sensor (not sure how I missed this). Has anyone found an app that turns the screen on/off by opening and closing a case?
My assumption is that this isn't possible without a proximity sensor but thought I'd ask.
Sent from my Kanged Tab2

Shouldn't be impossible at all.. the device auto senses what the screen light should be I do not know if it uses the camera for this or if there is a second sensor to accomplish this.. but it sounds totally feasible to write a program that senses total darkness to tell the device to sleep Im not so sure how turning it back on would work..this would be am awesome app please post back if you find one
Sent from my GT-P3110 using xda app-developers app

Here there, sorry I don't think it is possible, even smart cover app relys on proximity sensor.
And no, light sensor wouldn't work in dark places or at night.
I believe proximity sensor is only present in cellular models. If so, on your dialpad/keypad, type *#0*# -> sensor -> and place an object near the top of the tablet where the speaker and light/prox sensors are located.
Screen should turn green, and PROXIMITY:0.0 -> PROXIMITY:1.0

Im not much on coding but you would see some light at night from the screen unless the sensor just sucks or the case lets too much light escape i dont see why it wouldnt.

The sensors are only effective if light in shinning directly above it. If light sensors were this sensitive (picking up light from screen), I adobt putting a smart cover on or putting it in your pocket isn't going to work since neither pockets or smart covers are completely light proof as sensors are near the top picking up reddish/faint light.
Cover isn't flat enough to stop screen backlight from traveling accorss the surface of tab and therefore sensors won't be triggered.
Common sense

do you try the Power Switch Pro?

Power Switch Pro works with my Tab 2 7.0 and I would think it would work with the 10.1. There is a lite version on Play that you can try. I liked it well enough to buy it.

I'm using the wireless version. It works on my Samsung and also on the wife's rooted Nook tablet. It actually works the best when using the motion sensor and laying it upside down when you want it to turn off. A couple of times it didn't respond as quickly when lying on the back, but it works 100% of the time when laid upside down.

There is also a app at google play called Killswitch Lite.

power switch pro seems to do the job to a certain point. it works good outside, but when you are inside a room or place with a litle less light it starts to pop up that notification window and shut down the screen. maybe be it can be adjusted with the light sensor sensitivity but i found that so disturbing that i disable it.
for me it doesnt do the desired job. if someone has some idea how to make this useful will be thankful.

Like I said earlier

searsh smart cover on google play best one is about 2 $

I use Case Sensor on my Tab 10.1" and it does it's job. It does use the light sensor so during night time or dark areas, it won't activate thinking the case is still covering the light sensor. This app is clever in that when you press the power button, it will override the app for a temporary amount of time. Good enough until someone else can think of a better way to execute or use a combination on different sensors to control the screen

Magnetic sensor FAIL

used *#0*# menu to test the magnetic sensor; selftest failed. Compass apps are WAY off. its also reading 270-280T in field strength across several apps. I can recalibrate it (mag field strength detected) via one app, but the compass itself is off by about 85 degrees. I have not exposed it to strong magnetic radiation, stuck it in a microwave, or anything like that.
warranty repair/replace?
Also gyro won't calibrate and lists failed as well

compass/magneto apps now correctly report 47-51t (magnetic field scale) and i tested it with another magnetometer, also tested the compass feature through several apps against a real compass, as well as gyro calibration against a sextant (yes i actually have one lol, had to learn how to use it though first) it is calibrated correctly to within 1/2 of a degree; good enough for now.
I have no idea how/why it fixed itself, but the sensor tests still report 'failed', so its going back regardless.

I called Samsung a few days ago they said they would work on fixing my phone instead of swapping it out with a refurb, i told the lady i didn't want a refurb since i've had my phone in a case with a screen protector since day one. She was intent them working specifically on my phone but I'm still a little eh on that because back in the s2 days i got a refurb with a huge scratch on the screen when they said the exact samething. AT&T is willing to look at what is wrong with the and if they deem its not fixable they are going to swap it out with a new phone which is great. If you choose the Samsung option it take 2-3 days for them to receive it 5-7 days to fix it and 2-3 more days to send it back yet. They won't do Advanced Replacement either. Im just sad because my phone hasnt had any problems like the severe shutter lag or the over heating so hopefully when i get the new phone tomorrow there wont be something else wrong with it. $5 it has a dead pixel knowing my luck

I had the same issue when using a non-stock ROM/kernel. As soon as I went back to stock the problem went away.
