How common are dead pixels? - Galaxy Tab Q&A, Help & Troubleshooting

I bought the new Galaxy 10.1 3G tablet this weekend... first one had a quite obvious dead pixel near the center - I took it back.
Second one has a dead pixel about 8mm from the one side near a corner. These pixel's are tiny - so I would probably not have noticed the second one if I didn't specifically look for it due to the first ones problem.
I'm now at two minds about whether I should exchange it again... considering the price of these things, I would have expected it to be perfect.

U must exchange it to get a perfect one,remember that u buy a brand new item instead of secondhand one...

[Q] Do we still have to worry about panel type?

After 2.5 years with my trusty Vogue, I dropped it yesterday and cracked the LCD screen inside. The phone still works and I can sort of see what's going on on the right side of the screen, so I'm convinced nothing else is broken (including touchscreen capabilities). So, I ordered a new LCD replacement online and will try a little DIY repair when it arrives.
Right now, I have a Froyo build flashed to NAND on this phone. I remember way back in the cupcake/donut days, we used to have to set the panel to type 1, 2, or 3 in default.txt based on the manufacturer of the LCD screen in each particular Vogue. Since this is a replacement screen from an unknown manufacturer, am I going to have to worry about my panel type when it comes to booting Froyo? Is panel type taken care of automatically these days on Vogue?
Yes panel type is automatic for Vogue.
Thanks! After I placed the order for the replacement screen, I started to worry that I was going to have to set the type and that I had just lucked out in the past with the default on my phone. Since I can't see anything, I'm not really in a position to change any settings at this point.
Fingers crossed that my replacement works out. If I can't resurrect this phone, Sprint's offerings aren't particularly impressing me...

the LG optimus is prolly the best i can see at the moment other than the epic and evo, the optimus has the same gpu as the nexus one and an 800mhz processor, only short coming is that it doesnt have notification LED's i thought we moved passed that stuff years ago
Yeah, the Optimus and the Shift are the only two I really have my eye on right now in case my Vogue really dies for good. The Evo and Epic would be nice, but as 6+ month old phones, I'm hoping to limp along until the next generation of phones comes out. With Sprint's announcement about the mandatory premium data fee for 3G phones today, perhaps locking in with the Optimus for another 2 year contract before the pricing kicks in is a good idea...
I played with the shift today the keyboard slid really hard and the volume buttons are on the wrong side

Yuck, I wasn't terribly jazzed about the Shift in the first place, and hearing that just confirms I probably shouldn't go that route. I got my shipping notice about my new screen today, so hopefully I'll have my Vogue back to life by the weekend. I'm terrified that this thing is going to end up being panel type 4, which is to say, something that doesn't exist in the current kernel.
I have the LG Optimus S and it is quite nice!
Very responsive touch screen compared to the vogues screen.
Speed is really good, and there are already 2 replacement roms you can use.
Z4Root does the rooting automatically for you, no need to do a hard hack.
Tweaked kernels exist to allow the device to be overclocked.
Supposedly handles upto 32GB MicroSDHC cards.
Running a 16GB class 6 card in there now, it runs very smooth.
Battery life is quite good.
And - best thing, it was free, just had to renew for 2 years, which I was going to do anyway.
Update! My Vogue lives to see another day. My replacement screen came in the mail and is now working. I can confirm that panel type was not an issue, as Android fired right up and displayed correctly. Thanks to all for your answers and suggestions---my Vogue will not live forever, and I will probably have to pick up a new phone at some point.
Interesting outcomes from the screen replacement:
1) The new screen is much dimmer than my original. I think the backlight is less powerful. Of the three brightness settings on the power control widget, the new screen on high is comparable to the old one on medium. Also, the color gamut seems to be a little different than my old one. It's not problematic or anything, just noticeable after staring at that screen for the past 2.5+ years.
2) The pitch of the vibration has changed--it is a lower frequency now. Also not a problem, but a noticable difference. There was a little box on the circuit board in the lower left corner that was wearing a little rubber hat that fell off during disassembly. I put it back on, but I suspect that reseating the hat must have changed how it vibrates a bit.

Post 4 months (of the N7 release)

Wanted to get a feedback on the N7 run post its initial 4 months... I know all the issues reported were a small percentage from the actual, but are the old known issues resolved now? Are the latest units released from play store the next generation builds?
How's it going for you guys with the device?
I see GOOG doing a N7 with their N4 release (wow! ). Also see the ipad mini rumors coming true (wow, what a rip off). Really interested to see how's it going with this tablet?
I just bought a N7, and am loving every minute of it. The initial reviews scared me with so much going wrong such as the screen lift, GPS failure and other such reported bugs. I really haven't owned my tablet long (about a week or so) but I haven't experienced any of the complaints that were mentioned with the release. Everything works great on the device I got from office max. The main thing that all the complaints got me was a 2 year retail warranty, specifically because the manufacturer's has certain specifications for the glitches (is X number of dead pixels) for a replacement.
The 4.2 update is really all valid and mostly has to do with preference IMO. Hope this helped, because I definitely know the feeling after rummaging through this foum before buying.

I bought the original Nexus 7. I had a 16gb C80 variant. It was fine at first, but after a couple of weeks of light use (I was too scare to use it without a case), I got left hand screen lift. I took it back and got a refund. I was deciding what to do and then heard the rumours of the 32gb Nexus and thought about getting that. Then saw the 3g rumours and decided to get that.
I have heard that the latest "normal" Nexus's have improved in their build quality and that the problems of the early days are less and less. That said, I have not heard from anyone yet saying that the left side design flaw which is causing the lifted screen has been resolved. I "beleive" that they are still shipping units without the two screws on that side. It may be that is no longer the case, but I've not heard from anyone on here that it isnt. However, it seems screen lift etc is markedly reduced.
The 3g version has a re-designed rear. The microphones have been moved and there is now a sim card slot on the left side. I'm not sure if they have taken the time to address the screen lift design flaw, but my 3g has no problems currently with screen lift, bleeding, dead pixels, speaker etc. However, I've only had it a few days. I'm not about to open it up to see if its been fixed The 3g I have is a B0 serial number, so is a new model.
I was very uncertain about getting another Nexus and considered almost all the alternatives, but I'm glad I got it in the end. Currently its working great. Battery life is not the awesome figure I'm reading here of "2 days with normal use". I'm using it normally and I get a day out of it...mostly due to screen drain.
I have had mine for two months and so far I love it. My cousin bought one shortly after based on mine.

I've got an original 16gb pre-order N7. It arrived flawless and to this day has stayed that way. I use it a couple hours a day, no case and i have no complaints. Zero screen lift, no light bleed, no gps issues, speaker output is loud and clear. I Couldn't be happier.
Ya my 16gb N7 working fine since day 1. Never had any of the problems. Right now it's just the long wait for a custom ROM running 4.2 that sucks.
Have mine about 10 days (32GB) and it'll be replacing my laptop after i get an external HD to copy my music onto then laptop sold and just use the Nexus.:good:
32Gb WiFi only from Radio Shack. Some minor light bleed at top, 3 points - suspect screws are too tight. Flicker even without auto brightness on at low backlight levels persists on 4.2 even with strong WiFi signal - even with other custom kernels. Fix for all? Though hitting the battery - I just turn the brightness up a notch or two.
16Gb WiFi - flawless. No light bleed. Flicker very nominal, even yellow screen tint is very faint.
Newer Versions - not all issues are fixed yet. Go for replacement on the 32Gb? Haven't made up my mind yet. I suspect I will suffer the same issues with a replacement and not sure it's worth my time.
I'd picked up the 16gb one initially but that had a horrendous and completely washed out screen so took a refund and ordered a new one from another place and this one has been perfect. I love it and it's completely replaced my phone.

[Q] HTC One Stuck Pixels - Anyone Else?

Hi,
I have noticed that there are some stuck pixels on my HTC One screen by accident when using camera in the dark.
Has anyone else noticed stuck pixels on their device?
A 'stuck pixel' as opposed to 'dead pixel' is a permanently lit pixel (white in my case, clearly visible on black background) on a LCD display.

I thought I had two stuck pixels, but it seems to be a slight flaw in the glue between the glass and screen. For example, if the brightness is set to auto so that it dims in a dark room, I cannot see any dots. But if the brightness is high, and then view in a dim room with a black screen displayed, I see two dots. Those dots change in brightness depending on the angle I hold the phone. You may have real stuck pixels, but I just wanted to mention this weird phenomena that can look like them.
I have a very similar thing to what Jonstatt described. Sounds a lot like stuck pixels to me. On my third handset for this reason.
I'm considering contacting Phones4U with that issue. There should not be any display defects on a brand new, quality handset.
I did my third exchange this morning and finally got a flawless unit. Well worth it, and I would agree that there shouldn't be any pixels stuck on a brand new handset, especially if you are going to have it for 2 years!

yea i got a stuck one as well. It's in the last row on the far far left side of the phone so not noticeable but I know it's there ...
Shouldn't get this on a phone this expensive.
On the other hand my as well as many others on the forum's S3's screens were pretty horrible so i guess it's hard to get a perfect one.
Where are your pixels located ? is it enough to warrant a return ? thing is i got mine from phones4u in the UK but i'm in France now so wondering if I should send it back to HTC ?
edit: DAMNNNN just did the black picture test, so now I have at least 5 stuck pixels, wtf???
Pixel Fixer
there's an app in Play Store by the name of Pixel Fixer or something like that. There are a few free versions you could try identify if there is any dead pixels and it'll try to fix them. It worked for my old Motorola Defy, it might work for the One.
EDIT: sorry, it fixes stuck pixels...dead pixels are, well, basically dead...can't do anything about those.

Dear god not again.
This was same thing had happened with One X launch. I had to return 4 devices back to HTC to get the one without any dead pixels, or screen separation issue back then.
This time I have Developer edition on pre-order. If this one has dead pixels, I am simply going to return it and wont bother again. I am not going through the same thing I went with One X again in my life.
Na pixel fixing apps don't work for me
Man this is a real shame, might wait a bit for better versions to come and return this one to HTC even though i don't want to, such a great device.
This should not be happening on a high end phone like this. Gaps, dead pixels and hissing noise...
I have 7 dead pixels. This is crap. Wondering now as lots of people have this issue if HTC are cutting corners to make extra profits.

I have a small trapezium of stuck pixels, show up on green and white as bright, right on the edge on the left, about 3cm from the top of the screen. I'd say, given the pixel density on this screen, mine is a cluster of at least 4.
I debated internally about it for a week as it wasn't that noticeable, and the phone is otherwise free of the other common defects, tried pixel fixer apps as I'm certain it wasn't there on first turn-on, but have contacted the Three store who will replace. Here's hoping my 3rd (technically 4th) HTC One will be my perfect one.
I will be checking it in store for bulges, pixels, hissing, camera and so on haha!
So sad. Also keep pressing 3 dot menu when trying to press spacebar is so annoying.
Mine is going back and getting s4. Wanted a change and regret it.
Sent from my HTC One using xda premium
I've got a single dead pixel on the RHS about 2/3 of the way up the screen (in portrait mode). Can't decide whether to live with it or send back to affordablemofiles for replacement. Pixel fixing apps had no effect.
Spent ages in phones4u picking out a phone with no dead pixels, took three box openings.
Now found I have two bright stuck pixels! It's going back!
With one I bought online & returned previously, 4/4 have had pixel issues.

Why did you bought Optimus Black ? - Reasons

Hi Guys. I wanna start new topic. Tell me the reasons why did you bought LG P970.
First I:
- it was very good looking and with style what I like
- in 2011 this was one on the slimmest smartphones. I checked that on www.phonegg.com/top/12-Slimmest-Cell-Phones but now is out of list
- it was looking like Iphone 4 but with bigger display. Now is similiar to Iphone 5 black.
- I was thinking to buy Samsung Galaxy S1 but Optimus Black was better: have Flash, no pentile and screen brithness was much better (very important if I want to see something outside during sunny day)
- price was ok about 250 Euro
- I was quite sure that device will get Android 4.0 because was avalialbe on May 2011 in shops. ICS was realased in October 2011 (18 months support for updates )

Now your turn
My OB is a 2nd hand phone. i like its design, and it has the world's brightest display the nova ips... it is still the brightest today but not that crisp as the new technology displays like htc lcd2 and amoled2. who cares... i got a phone OB that when full brightness on full white screen fully lights up a big room like a florescent lamp... hehehe
4". Good display. Thin.

My black was the best phone I could had been obtained while I change my ITSP.
And Im proud of what I selected
After this phone, lot of L series came, and some others, even so ours is best and unbeatable
I don't wish to sell..

I bought it, because it has 4" display, 5 Mpx camera, CM support, official android 4.0, and also it has good value to money. I bought it for 500 zł (Polish money), for example SGS4 costs 2500 zł.

I wanted the O2X but it was too expensive even with contract so I got the OB instead.Not a bad decision.
Sent from my LG-P970 using Tapatalk 4 Beta
Same as the OP really... got it when it first came out in Germany, that was 3 years ago - along with a new contract so "free".
I still like its style, looks, size and display (was getting crazy searching for a new smartphone, because I need the high screen brightness and couldn't find a new phone that even comes close, lol).
What I didn't like were the initial very bad stock roms (battery life of ~10h idle...), the occasional slowdowns and keyboard crashed I got using stock roms, so I rooted and used a variety of custom roms. Phone is still running good, but I am now considering to buy something new, probably the Optimus G. I just need more performance for multitasking, plus my GPS has been acting up for a while now.
All in all I don't regret getting the phone, as it is one tough piece of hardware. It has fallen down like 50 times, been used daily without a hull or cover, gotten wet, been full of mud, and it still works No scratches on the display either, just the back plastic cover is full of them, but who cares.
I bought it because it was good looking and thin,with nice hardware and the brightest display.
And all of these at a reasonable price.I love it!The only thing that i miss is the USB OTG feature.
it was cheap when i bought it. switched from Samsung Wave 2 because of bigger (better) screen, slim body and android.
dropped it several times but still without scratches or cracks :angel:
do not regret it. should have purchased it in black color, though

Very much the same as you,. It was the IPS screen that won me. And if it gets somehow USB OTG I will be happy camper.
It has served me faithfully for over two years and it is a definite value for money. After all this time without screen protection there are only couple of very fine scratches, not visible when looking straight to the screen.
Only real downside is battery being bad to start with and gone worse over time, which turned out to be related with LGs chip design .
P.s. I came from nokia 5800 and samsung wave 1
I bought it since my dear Samsung Wave 1 was stolen and this phone was the best about quality/price. I have to admit that seeing knzo create the very first topic of our forum had helped.
I got it because it was light in weight, the awesome display, not to big, good hardware specs at the time, good development of custom roms and a good community to back it up.
My ob is second hand !!!

It was a great phone for the price he had, and the look of it was very worth it.
First for the screen, secondly for the design. Nova is stil one of the best screen (very bright, neutral colors and large angles of view), even versus newest phones. My girlfriend has a S3, Nova beats its over-saturated amoled...
Because its cheap and I got it as my second device. Am also gonna use for devment

1) 4 inch screen back then (2011) was considered as quite big
2) thin and light
3) couldn't afford more expensive device as I'm a student
never baught it, my good old sister had the OB and SG-S1 for her daughter. she went on and got her self another SG-S1. so i asked her to be a loving sister and give her brother a present.....something like OB.
i had SG Gio, and it was nice until i saw the light with the OB. i like its size, screen, weight, and overall looks. i use it for almost a year and its still rocks. and since i got it from sis, i never say no to presents and passed my Gio to the wife.
mean while my sister upgraded both hers and daughters phone, she got SG Note, and for her daughter SG-S3, so i asked her for her old SG-S1 in order to compare with the OB. she gave me both her SG-S1 for me and my wife. my wife sold the Gio, and she is happy like i was when moving from small screen phone to a bigger one.
as far as for me, after 2 weeks of using the SG, i still like the OB better. they are so similar with the specs but still screen is way better and the camera has the flash which is a plus for me.

Repair vs Upgrade Pixel 3 (Screen, USB C connector and ear piece)

Sup sup. I did make my research before posting, but the posts that I found were old.
I have found out in the bad way that Water Resistance degrades over time. I placed my 2 year old Pixel 3 phone in a pool and the screen got screwed (I'm having stripes all across the screen) and now it needs to be serviced.).
In addition, about a year ago, I also submerged my phone in water (all great! Took awesome pics) but stupidly decided to charge it without letting it dry... And Bam! The USB C connector got damaged and it only connected from one side of the USB C (The irony) .
Considering that the bill of materials to replace the device is around $150 ($100 for the screen + USB assembly $20) + servicing costs ($30), it would be in the $180-$200 ballpark.
This brings me the important question, should I upgrade or should I fix my phone?
I'm pretty happy with the Pixel 3. I was planning on Keeping it 5+ years (using custom ROMs), but honestly, I don't know if it's worth it.
I was thinking on going with a Pixel 5a, but the Snapdragon 765G is similar (and in some cases worse) than the SD 845, so I don't know if it makes sense.
I've been using Google Phones ever since 2013 (Nexus 4, 5X Pixel 3), but I don't dislike change.
But I dislike paying more than $500 for a phone, except iPhones (Pixel 3 I got it for $500 from Google). If I were to pay more than $500, I'd go with an iPhone instead.
Therefore. Should I fix or upgrade my Pixel?
Thanks a bunch
