[Q] Complaints I heard - true? - Xperia Tablet Z Q&A, Help & Troubleshooting

Some oddball complaints I just heard (not saying they necessarily make sense):
- Screen image yellowish: Apparently an early production issue?
- Power button sort of wobbly
- Bad protection film on screen ( can't it just be pulled off and replaced by a 3M or so?)
- Videostream playback crappy when Bluetooth is active?

Protection
I have seen the display protector on Youtube, he thought it was a standard one and thought it could be taken off, so I would say it's not good. Maybe we can just replace it

I can confirm that on me device (SGP311DE):
Screen image is yellowish!

my SO- 03E screen is heavy yellow!!

will you return it?

Compare the Xperia Z display to a white sheet of paper. If one has other devices (many of which can have a blue/hi temperature cast to them) the sudden change to a white or even a warm screen can look very yellow.

It has a yellow tint compared to a white paper too.
I am not bothered by it though.
So, basically:
screen yellowish: yes.
power button sort of wobbly: yes..but not even close to the "I am afraid it will fall off" area or something like that.
bad protection film - cannot confirm, the film is fine
bluetooth audio - got nothing to test that.

On my Tablet Z the USB port doesn't deliver enough current to power a 2.5" external harddisk.
The disk works fine with a Nexus 7 and an Acer A700.

Screen colour looks absolutely fine to my eyes.
Power button is a little bit wobbly. I can't understand why that would bother anyone though.
I immediately removed the screen protector film. It looked like standard packaging stuff rather than attempt at a proper permanent screen protector. I never use screen protectors anyway.
Video playback of a full HD movie with sound playing through bluetooth speakers was faultless.
Hope that helps.

err... You do not mean the sticky tabe which was on the screen fresh out of the box? Because that isn't the screen portector film.
Do you still have the Sony logo on the top left? That one is printed on the screen protector film, so if you had removed it there would be no logo anymore either.

I do still have the logo, in which case I would say it's very, very good screen protector film.

Is the back of the tablet made by the same back material used in the xperia s?
And is ir true that the wifi models don't include sd card support?

- on 3g model - it's perfectly white, without any yellow hints, but I heard it's a problem only with wifi-only models. But cannot confirm, since haven't hold them in my own hands.
- kinda, little bit, doesn't bother at all.
- Yeah, it is bad. It doesn't really help with fingerprints, and it scrathes really easy. I've removed it on my tablet, and, by the way, logo printed on tablet itself, not on the protection film.
- haven't tested it, but even if so - it sounds more like software problem, so it can be fixed in the future.

WOW, I didn't even know there was a screen protector on it, I bought one with the table and was slowly getting round to fitting it...guess I have a spare now.
I've been very happy with mine, Bluetooth audio and SMB movie streaming from my Windows server works great. Powers my external SD card reader without additional power.
But I have just raised a case with Sony about my screen, since this morning I've got a very yellowish area along the right hand side of the screen, only noticeable on light backgrounds. Looks like a burn mark or something similar.
Will have to see what happens there.

Last time I saw partial screen yellowing along an edge, it was due to glass separation along that edge from the chassis on a 32 GB Wifi Nexus 7. The image was also grainier than on my old (and currently only) 16GB Nexus 7. Don't know if that helps in the diagnosis.

Did you put a new screen protector on? From the sounds of it I'll be taking it off straight away, but I don't like screen protectors, so I don't want to add another.
If so, is it fine? Are there any hairline scratches? Cheers

No I haven't, but plan to do it later, cause the screen itself attracts to much fingerprints. But in terms of scratches - there are none so far, even though I don't use cover also. And I doubt there will be anytime soon, cause if I'm not mistaken they use dragontrail glass, same as on Galaxy Nexus, which I didn't bother to put protection on, and which is still like new even after a year of intensive usage.

[Q] Change sensitivity of proximity sensor

Is there any way to change the sensitivity of the proximity sensor. It seems every screen protector I try makes the screen turn off when in a call even without anything near the sensor. I had to cut one of the screen protectors to get around it (but had messed up a corner when applying so I replaced it)
Or is there a way to completely disable it so I just have to hit the power button when in a call to manually turn the screen on or off.

Dont have the same problem but would be helpful.
There is a distance setting in the build.prop file. You could try adjusting that and seeing if that helps.

Perfect. Changed the value (increased it from default of 60) and its working great now. Thanks for that tip.

Well after further testing seems that it didn't fix the problem. Seemed to work when I first made the changes but now the screen is stroll turning off and no matter what I change the value to I can't get the proximity sensor to work right.

According to the official Atrix manual -
http://www.motorola.com/staticfiles...s/StaticFiles/Atrix_US-EN_UG_68014798001B.pdf
Note: Your touchscreen might
stay dark if the sensor just
above it is covered. Don't use
covers or screen protectors (even clear ones) that
cover this sensor. To find Motorola accessories for
your phone, visit www.motorola.com/products.
Anyway, why do you guys keep using the screen protectors with this gorilla glass phones? I have carried Moto Milestone in my pocket for a year and D2G for 3 months and there are no scratches on them whatsoever.
I use them on every phone I get because although it is gorilla glass it can still get scratches under the right conditions and I for one do not want my $400+ phone to have a scratch on the screen. Never had a phone that had issues like this with screen protectors and the proximity sensor. Multiple iPhones, Dell streak, nexus one, droid, galaxy s. I've tried two different screen protectors with the atria and both have this issue.
I'm having issues with my proximity sensor too, but it seems that I can't make it turn off the screen when I'm talking. I'm not using any screen protector but I do have a case. It was working fine till a week ago but now I just have to block the phone every time I get a call.
The only difference is that I've installed 2 new games, maybe those are affecting the sensor?
Another thing that isn't working anymore is the auto brightness that's always set to minimum, no matter the light conditions. The phone is online for 260+ hours already (had it go to 500+ before but had to turn it off to add a micro sd card, just to be sure it would find it).

Ugh... thing is if you drop your phone, it could crack both with screen protector and without one. If you grind the screen against your keys, it will get scratched through the protective film.
If you use it normally - the chance of scratching it really small. Just my 2 cents.

My wife's phone had a screen protector on and got scratched by being in her purse. The actual screen though had no marks. The screen protectors help. Obviously each incident is different but they can help prevent some damage so in my opinion they are worth it.

Hi there,
Got the same trouble..... but I just noticed it work fine at the sun (outdoor)..... turn the screen off in the shadow..... and switch on in the sun....
so I think a light adjustment has to be done.... but where ?...
Thanks to developers

if Samsung cant find a solution you must (lightbleed)

i just wonder why the **** some N10s has no lightbleed and others has it all over the screen.
WHY?
thats the big question.
has anyone opend their devices and found something that differ from others or found some loose/to tightend screws?
also i wonder why it is on some devices that the top half is brighter than the bottom screen?.
also i wonder why some people at samsung quality check havnt got fired yet?
its about time they do something.
I suggest we create a thread "Post photos of your Nexus 10 showing a black screen at XX% brightness". That would be a "wall of shame" to send to Google/Samsung. Not sure what the XX would be. 75%? 100%?
Doesn't really matter if its 75 or 100. The camera will auto expose and the images and exposure for every different picture will be different.
I dont care about light bleed, its minimal and I dont see on normal conditions.

The only time I notice light bleed is when I boot up, and and I'm like wtf? I have then I quickly forget about it until I see a post on the forums about it.
Yeah you only notice it on screens with black background
Over the last few years I have haunted the Asus Transformer (through several versions) and now the Nexus tablet forums and ALL tablet products have various levels of light bleed which vary even between devices made on the same assembly line. It is like an echo that never dies.
If your device cannot be used due to excessive light bleed then RMA or sell it. If you are expecting no light bleed then, at this time, with this screen technology, tablets are not for you. From what I have read it does not matter which manufacturer, tablets have lightbleed.
This may sound harsh but see for yourself by reading other Tablet forums. You will read similar to identical complaints. Some perceived and some real (ASUS Transformer TF201 WiFi strength):
> Lightbleed
> WiFi poor signal strength to repeated dropped connections
> Poor build quality
> OTA releases that break something
> Poor video playback
> Interface stutter
> Reboots, poor battery life ... etc
I am not saying that you should put up with a poor product more that you should vote with your wallet and your consumer rights like RMAing a defective device.
The thing is about the N10, people might be able to deal with it if it was just some bright spots, but the thing that kills me is that they're bright yellow spots which can easily be seen in the bottom right menu bar thing at all times. This is by far the worst tablet I've ever seen in terms of lightbleed.
I never use my tablet completely in the dark at 100% brightness. I saw the light bleed when I tested it after reading these posts but then when i turn the brightness back down to 50% its gone. I don't even notice it in the dark parts of movies. I understand that there are probably some worse cases than mine, but sometimes I think people are too picky.

I am not sure if it's a matter of being too picky. I think what kills is that the lightbleed on this table is yellow. If it was white I would tolerate it better.

My minor light bleed is pure white.
I don't have any issues with lightbleed on my N10. Is it there an I don't notice it? That may be the case, I guess I don't stare at a black screen and have unrealistic expectations... Great tablet and would recommend it to anyone!

You must not understand manufacturing at all
I opened my N10, the screen is sealed with the front glass inside a plastic frame. The only screws inside are on a metal frame that holds th battery in place, which have no effect on the extent of lightbleed.
With tablets nowadays even with the Asus (which I've tried myself), the screen is attached to the touch panel (digitizer) via strong double sided tape. The screen is really thin so any flex during installation will cause it to be uneven causing some of the light bleed. You can probably remedy it by using a blow dryer or heat gun in low setting to be able to lift up the screen from the touch panel where you have light bleed and even it back down. You have to be careful not to bend the screen too much or it will crack. Again this will probably be a very thin screen (about 2-3mm) and fragile screen. IMO dont even try it and just get it exchanged and hope you get a better one.

The screen is fused to the digitiser, ie no double sided tape, and it is impossible to separate screen and digigiser

Not sure youre right. I work for an ATM company and we have touchscreen machines and the touchpanel is sandwiched in between the LCD and front glass. But on tablets the screen is not fused but they use a double sided tape. Whats probably fused is the gorilla glass and the digitizer. Post edited
Also I know this because I've completely removed a dead screen from an asus prime before. Once you have both separated the glass has a thin film (digitizer) on it and on the bottom of the film is a ribbon cable. The screen itself has nothing on the front but a thin 1/4 foam tape around it.

I might have misread your post, but I was talking about the nexus 10, Sorry for the confusion
It used to be that there was a piece of double sided sticky tape (like I have on my old tab) between digitiser/ protective glass and LCD screen. For the nexus 10 howver,this website says its all fused together
"Everything else seems to come out just as easily, according to the write-up. But the Nexus 10 display and digitizer are fused together, so there's no chance of separating the two. " http://crave.cnet.co.uk/laptops/google-nexus-10-rated-extremely-repairable-after-teardown-50009785/

This is a ridiculous statement ..there are plenty of tablets without light bleed and everyone should expect to not have light bleed. Now the bleed I'm talking about are the blotchy spot types where there is glow coming from one area that extends out from one/multiple areas. Which the N10 has very bad blotches. Totally unacceptable. Slight even "leak" around the edges is one thing but a yellow blob coming out of a corner when you watch videos is ridiculous.
My HP Touchpad made my 2 N10s look like crap in regards to light bleed. Yeah, a touchpad.
I hope they get it right soon... prob will give it another go in a month at a physical store if I hear good things

Does anyone here NOT have light leak?

I've been suffering the dust issue on 2 lumias now, and have noticed something. If you go to a darkish room/area and tilt the phone, you can see the light from the backlight coming through on the sides of the screen and also at the top and bottom by the capacitive buttons.
e.g. http://discussions.nokia.com/discus...ith_Windows_Phone/30650/1/2012-12-15-1679.jpg
I'm just wondering if there's anyone here who can go to a dark area, and see whether they all have this or not? Kinda worried me because made me think there's a manufacturing defect here and the screen isn't secured properly on the handset - which could maybe account for dust getting in? It might also explain the 'rattle' on vibrate that some are getting.
The three lumias I've seen all seem to have this to a certain extent (the light on the sides is usually much thinner and normally on either the right or the left - not both).

How would you define the light leak, eg, if I look at the screen on a very extreme angle, I can see through a minute gap at the bottom and see light from those buttons through it through the screen, but in normal circumstances it isnt noticeable at all. like the light isnt uneven or anything like that

Well it's like in the picture link that I put on the first page - Except as well as the top and bottom, there's also a small amount on the sides too that can be made to partly disappear if you push down hard on the screen there - I.e. the impression the glue holding the screen down is loose. It appears on all the ones I've seen, but I don't know, if you guys say you haven't seem it maybe I've just had extraordinary bad luck! It doesn't affect the screen when looking at it normally but it makes me worry for the future - loose things tend to become looser with time, and my theory is this, the dust and the vibrate rattle are interconnected.
I'm looking at my 920 and I think I see what you mean. On the top I see the light across almost the whole top but not at the sides or bottom. Is really a concern (I don't look at the phone at an extreme angle like that..)

Oh ok sorry, I didn't look at the pic. The vibration rattle (from what I've read) is just how it is because of the kind of vibrator (for lack of a better word I can think of) technology. Would have been good to have a nice clean vibration humm being a flagship phone...
Nothing seems to change for me when I compress the screen. Perhaps you really did just get a bit of a dodgy one?
Me either. I just did it again to make certain I wasn't lying to you. I cannot see anything from any angle. Now I'm starting to feel a little guilty.
I'm on my second 920 because the first one had a problem with switching back to handset mode after unplugging a headphone jack, but neither of them have any light leak! Maybe it is a manufacturing defect because of rushed batches due to the supply problems?

Can You See Screen Scratches?

Hey folks,
I'm looking to buy a used phone on ebay. The description says that the screen has a slight scratch on it that can't be seen when the phone is turned on...only when it's off. Having never had a scratch on any of my phone's screens, I can't easily verify that claim. Does this have the ring of truth to it?
If you've had a slight scratch on your screen, does it really only appear when the phone is off? What about when the screen is dim? Or what about at different angles, etc? Does it pretty much always just disappear?
Thanks

I love my Xperia Z4 Tablet. However the backlight is noticeably dim on the bottom (when in the default landscape position) or the left hand side when in portrait (volume/power button facing up). It is most noticeable in portrait mode when there is a white background (Kindle, Chrome and Instagram most notably). I am willing to live with this issue, but was wondering if anyone else is seeing any issues?
For the price I paid, it would be nice to have uniform backlighting. But I am worried it could be worse on another unit. Expansys has offered me an exchange or refund but there is a delay in availability now that the first lot has sold out.
No problems with mine
I am sending mine back for an exchange. I miss it already
Now I noticed that too. The difference is really small, but it's there.

Hopefully my replacement isn't any worse than the one I just sent back. It was as bad as I could handle.
Interesting, the same with my tablet - seems to be a general problem
I don't know if I should return and change the tablet...
can you make a picture for us? I dont know what you mean? my backlight is perfect - no bleeding and no clouding )
I'm sorry, but it was not possible to make a picture where you can see this.
However I can only see it on white backgrounds - the first centimeter is slightly grayish...

It is not a hardware problem. I see the band only when the bottom menu appears. It looks like the transperancy issue with that menu layer.
Mine looks fine, just hope it is not something my eyes just don't notice, but others do.

No, I think it is a hardware problem - if I turn the tablet from landscape to portrait mode, white backgrounds are gray on the left. Btw for me it's only visible in portrait mode - in landscape mode the menu bar on the bottom is usually black or transparent...
It is definitely a hardware problem and it sounds like the backlight is weaker on several units on the bottom (when in landscape) or left hand side (when in portrait with power button facing up). It is a shame as it is very distracting to read on anything that doesn't have a dark or black background in portrait. Still waiting for my replacement unit As long as the replacement isn't worse, I will likely live with it as I really enjoyed (and miss) the tablet.

Try anything with an all white background. If you open Chrome with no web pages loaded and the new tab page up or Kindle with a white background and hold the tablet in portrait, you might see uneven backlighting on your left or right sides depending on the orientation.
Backlight direction is notable
Got my Z4 tablet yesterday. After reading some issues with the backlight I checked this at my device and can see there is a notable uniformity.
If you hold the device with power button upside, then one can see a thin bright line from the backlight LEDs on the left side, while the opposite screen edge is slightly darker.
It looks like the screen is only backlighted from one side. For the normal usage it is not really annoying, but it is there and you would see it, if you take attention for the issue.
Do other Z4 owners have the same effect?

I have the impression my Amazon Z4T packages was already a replacement from someone else. The box made used look, some scratches and one corner had a ditch.
It wasn't sealed in any way. The charge adapter cable looked out of its the small box. The screen protection layer made the impression it was reattached, a lot of air bubbles were included.
Can someone describe how he found the delivery when unboxing it?
Was it sealed?
I also consider a replacement, if the screen issue is not a general construction feature.
Oddly enough, I purchased mine from another supplier, and also felt the item had been handled if not used. USB cable was out of wrapping and screen protector had signs of being removed and re-applied. I received mine the day after they were available for sale. I am hoping my replacement looks like new and has minimal or no backlight uniformity issues.

Hopefully you get it soon and can report here the condition of the replacement.
I have 14 days left to send it back to Amazon for free.
Please also describe how it was packaged.
Are there any seals or blister foil?
I can't believe Sony delivers an open package to retail stores.
Unboxing videos on Youtube don't show this clearly.
Thanks in advance.

For me:
Not sealed.
Box in perfect condition.
Screen protector had a few bubbles, but not that many.
It was perfectly even on the tablet, edges protector = edges tablet.
Charge cable was in box, but it was wound a bit loopsided. But I think it more likely that it came that way - besides, how many people do even need those cables nowadays? Even if they need them, they likely will not use them when trying the tablet out.
Charge of 65%
Tablet itself:
I couldn't see a backlight uniformity issue, tried it with a white background with 100% luminosity in a dark room. Compared to the Z1 Tablet the screen looks a LOT dimmer in the dark, but I suspect that is more because the Z4 has some auto-dim function there. In bright light the Z4 screen looks slightly brighter.
What I noticed is that the speakers produce a fair amount of white noise. At 10% it is very noticeable, at 50% I do not hear it unless it is a very silent scene and I am concentrating on it. Somewhat annoying and IMO not something a tablet in that price range should have, but not annoying enough for me to play replacement bingo.
My seller is out of stock with a new batch due next week. I'll let you know when it comes. From what I can tell, Sony products are never fully sealed.
