Nexus 10 ALL Issues Check

Hi, everyone, I ordered my Nexus 10 and Hope everything is manufactured perfectly. I have been reading many Forums about the Nexus 10 Issues and still ordered one and sent a Message to Google Play Support to make sure they check my device before sending it, and also send them the Xda Nexus 10 Forum Link...
Well for those of you that will buy the device please check for all these issues for the 15 Days, because after that you cannot return the device according to what I understood from Google's Refund Policy? I might be wrong .

These are the all the problems I read about here on Nexus 10 XDA Forums. I haven't received my Device and I Pray that I do not get any of these Problems and that any future Nexus 10 Buyers don't get it and that Early Buyers get it solved because this is Really a Headache in Purchasing Online that no one should have after paying $439 to $539, It makes people or is it just me? want to go buy New IPad with Retina Display. lol... I LOVE ANDROID and I LOVE GOOGLE btw..

Check multitouch, either via a free app (one that is specifically for developers is probably best) or the pointer location under developer settings. On my Nexus 10, anything past 2 finger input is unstable (appears, disappears, jumps across the screen, etc.).
Not 100% sure if it's worth returning the tablet or not still since... I'll probably never use more then 2 fingers at any point, but I'm pretty sure it's an isolated issue (I made a thread, but I think only 1 or 2 people confirmed it didn't happen to them).

Mine has a brightness issue. On the right side when in portrait mode (camera side) it shows a bit less brightness. Like a small shade. It's not that obvious on films or games, but it is a bit distracting when reading on white/bright backgrounds.
I've already sent a message to Google asking for a replacement.

Be sure to check WiFi connection and speeds as well. I have read a lot on the flakiness of some devices on 5 GHz bands. My device literally is 40x faster and no longer drops connection intermittently when set to 2.4 GHz only. I almost returned it, but decided that it isn't that big of a deal compared to some of the issues that others are experiencing.
Also, food for thought...I had to RMA my N7 when the screen deadzone issue came up. It didn't get really bad until after about 45 days, but I had no issues with customer support back in August. They happily exchanged it well after the 15 day window and asked if I wanted a refund or replacement, so I don't know if they changed that recently or what, but I guess YMMV.

I wouldn't go looking for problems, if it works fine then don't worry about things that MIGHT be wrong. If issues pop up, well, then get them addressed, but don't sit there all day going "Oh no, is it going to explode today?" No offense, but I think some spend more time looking for issues and worrying than actually enjoying their devices. As for mine, well, it's running along without issues, so I'm happy

My notification button is not working. Anyone with the same issues?

I am having trouble with NFC. Android beam and NFC are both on but don't seem to work. I'm putting my Nexus 10 to the back of my Galaxy Nexus. I've used another nexus as a test and no luck.
I EVEN REPLACED THE DEVICE through Google Play support and no luck. Any thoughts?

so how did the tablet do ..was it good?

I have none of these issues. I don't have another device with NFC and so I couldn't test that, but everything about my model says well made. The light bleed is no more than on my old ipad2. I thinks its good you provide this list. I think we should look for problems. We spend a lot of money and want what we pay for. Nipicking begets improvements!!!

I had to RMA my nexus 10 today after maybe 30 min of use.
Half my screen, split longways right down the middle, went black. Not completely black, but much darker so much so that certain images, icons, etc on that half werent visible -- there was also ghosted images left in that half when you change screens so that you could still lightly see what was previously there.
Obviously a display issue, but contacted play support, did a factory reset which obviously didnt help, and just RMA'd it after that. At least the return was easy and theyre sending out a new one.

I just got mine and everything is perfect. I couldn't ask for a better tablet. Except a few reboots on the stock ROM and one so far on aosp+ no problems here. Haven't tested NFC yet. I'll test when I get my nexus 7 back.

@snoopyods
Might be a stupid question but did you put your NFC sensor from your galaxy nexus on the Nexus 10's NFC sensor? (it's located near the camera)

Almost all of the issues reported have a very small number of viewings and responses which shows that the reported issues are not a problem for the vast majority of people.

you really think by emailing support to "check your device before shipping" they will actually do it? haha... i feel sorry for you.
Its not like a one man show over there. Support is probably nowhere even near the shipping warehouse.

Hi all
I've not managed to USB otg (does not detect a stick or power a usb mouse)or HDMI out (no feed to TV) working, I've ordered replacement cables (although the originals weren't cheap).
I'm concerned that it might be my N10 and not the cables.
Anyone's had issues like this.
EDIT: It was the cable, had USB stick, mouse and PS3 controller over OTG cable. And playing and watch stuff on TV via HDMI. Very cool!

Why do you recomand to check the screen with black and white background with different light level plzzz ???
Has any body can notice a litlle bit of vertical lignes on white background on screen ??? Is this normal ????
Thank's. Anyway i just have a little light bleed not importante but these line .... Hum mm... Not very noticiable. You have to watch very well

OMFG received mine from US 2 days ago ... Im in Colombia and have the problem loud low pitched sound with low light (discovered on the bathroom while ehem...reading haha) high pitched low sound with brightest screen level ...fortunately the tablet came with damaged corner apparently from a fall to the floor so im getting a compensation for the total price of the tablet from the ups subsidiary company..and get to keep it... since none of your tablet fell to the ground im now assuming fall is not the reason of screen screech ....RMA its out of the question... Will there be another solution toy this? Im watching vídeos of n10 dissasembly and its very easy...or should i just let it be since apart from the noise the tablet works flawlessly and im getting all of the money back??
PS sry for my english...

Mine suffers from:
- Bad WiFi
- light bleeding
- multitouch issue
- bad led notifications
I should play the lottery...

Camera issue
I have a problem with my camera. It worked out of the box for a day or so and didn't anymore after the update (maybe it's not even related). I reverted back to JOP40C, it didn't work. I tried CM10.1 it randomely worked for a few days, then didn't work again. Does anyone else have the same problem? I'm hardly using the camera but it just sucks not to be able to fully use my device. Thanks in advance for your help.

Have you tried "led color tester" from the app store? I had never seen my led before using this software. Turns on all colors, no problem... So it seems like it is more of a software issue.

Moto X Screen burn-in

I bought my Moto X around the end of September and about two weeks after getting it, I had a screen burn-in from the notification bar and navigation bar. I let Motorola know and they happily replaced it. However few weeks after owning the second one I experienced the issue again and I let them know. They told me they were stunned and that I was literally the only person who had reported the issue.
What I am wondering is if anyone else has experienced this. I know it is a common problem with AMOLEDs, but I didn't expect it to happen so soon.

I saw burn in on a display model at Best Buy. It was the big Motorola M logo that displays at the boot animation. If you looked at a white web page or any solid, but light colored image, you could see the ghostly circle the size of a quarter complete with the swishy M in the middle of the screen. Got them to open a second demo model and boot it up so I could see a clean screen and bring it to their attention. Weird thing to have burned in, too.

Op did you leave both phones display on for 2weeks straight at 100% brightness? Lol
I have had mine for 2 months, do at least 4 hours sot daily, most of which is on reddit and xda, so nav and status are almost always static... I have zero sign of burn in.
I had it pretty good on my s3, but I blame ingress for that... Being outside playing so much and had it at 100% brightness because that screen was so dark... Even then it took at least 2 months before I saw any burn in and I was playing A LOT!
Can't imagine how you would get burn in on two devices, each in two weeks... Seems like that's a feat that you have to try and do, lol.

I'd be hard pressed to believe this as well... I've had numerous amoled devices and abused the crap out of them and even then, it took months to get any sort it noticeable burn in... If it were one device then I wouldn't second guess it, chalk it up to manufacture defect... But two in a row? I'm curious as to what the op uses his phones for and if he ever turns off the screens... Even store display models take a while to get burn in and they are on 3-4 times as much as a typical power user.

I'll have to send you a pic of my GNex then, so you can see the perfect "ghost" of a Pandora logo in the middle of the screen from running the display full time in my car dock.
I also remember similar complaints when the GNex first came out, of people claiming they were getting burn-in on the notification bar area, and I thought they were ridiculous at the time. Now, not so much.

It happened to my gnex, so I'm not surprised that it happened on this phone too.
I'm not saying you're faking it, but 2 weeks is a little too soon for it to be happening. The gnex only had the issue after a year or so. Are you keeping the display on all the time when charging or something?

They will eventually burn in if you set the screen to never time out and leave it displaying the same thing for hours or days on end. Most store models have some level of burn it. In normal use cases it should never be an issue though.

Just passing by, but 2 weeks is entirely possible.
If you keep using the phone with the notification bar displayed and then two weeks later open a full screen browser, you will most likely notice burn in if you look close enough.
It's extremely easy to do.

I bought an S3 from ebay with real bad screen burn in (that the seller didn't mention). She actually didn't believe me and accused me of scamming her until I replied back with a contact name and number that was burned into the top of the screen from the messaging app (the keyboard was also burned in, I guess she constantly texted this person).
I think burn in is more likely to happen when brightness is higher. I had a GNex and GS3 that never got any sort of burn in but I also rarely had the brightness above 50%.

you know, now that I look, I have it too. It's faint, and I thought it was from the Nova Launcher beta, but ****, this is screen burn in. Damn.
---------- Post added at 05:26 PM ---------- Previous post was at 05:13 PM ----------
I don't even use my phone that much. Generally around 1.5 or 2 hours screen time per day. Brightness is about half. Kinda crazy.

Recommend using an app such as:
https://play.google.com/store/apps/details?id=com.feetstech.screenburn&hl=en
to minimize this. Most plasma TV's have something like this built in as they are also prone to burn-in. Use it for 10 minutes every once in a while (even if you don't see burn in) and it should prevent it.

I got screen burn in on my S4 after 2 months. But I also blame ingress for that. I have a X coming and hope to minimize that by not playing ingress so much or play on another device. One thing that I do for the status bar to help out is with nova launcher I have it set to swipe the notification bar on top away. I try to leave it off the screen as much as possible. But yes amoled screens suck for burn in.

I usually turn my phone to the 270 degree position to have the navigation bars switch sides every now and then. That helps a bit.
And with AMOLEDs, it's more important to turn off the screen when not in use rather than let it time out. I have mine set to 10 minutes, but I usually manually turn off the screen because I know AMOLEDs are prone to burn-in over time.

[Q] Nexus 4 touchscreen and Battery Issues

Hellllo everyone!
I bought a Brand New Nexus 4 a 5 months back from an unofficial distributor. In the Beginning I loved the phone, but now this phone is really giving me a lot of headaches lately.
My first issue is the Ghost touch and dead zone issue that has been affecting quite a few G4's lately. (Since I enabled "Show Touches" in developers options,I am able to see any touch inputs on my phone. )
The ghost touches occur right in the middle of the screen (Right where the dead zone is) and the ghost touch issue disappears when I lock and unlock the screen.
The ghost touches may show up again after a minute, 10 minutes or maybe even the next day.
To my dismay, I think that a new dead zone has appeared (however, much smaller than the dead zone in the middle) a centimeter above my Navigation bar.
My other issue is that when my battery reaches a certain level, say around 25-38%, the whole screen erupts in a fury of touches all over the screen. My phone is rendered unusable, until I charge up the phone.
And another issue is that when I restart my phone, the touch screen sometimes does not respond at first. It then starts working after a while. It could start working in 1 minute or it could start working in an hour. This particular issue only happens when I restart the phone
Honestly, I have taken care of my phone, and never dropped it or abused it in anyway.
I read reviews about the whole "Amazing Quality" of the Nexus 4, and was bought on looks and design of the phone, but right now I'm really starting to regret my choice, and wish I went with an Xperia Instead.
Sadly, since there is no official LG or Google Service centers where I live, and since I bought this phone from an non-official shop, I'm unable to send it in for warranty claims.
I'm quite adept in opening up electronics, so I have no issues opening up my Nexus.
Does anyone know of a way to fix this phone, without a Digitizer replacement?
And is there anyone out there facing the same problems?

You still have lg warranty regardless of where you bought it from. Its more likely that you got a refurb though. In terms of fixing it I think you are in for a new screen.

Hey, thanks for your reply
There is no official warranty where I live, so I cant RMA it to google or LG.
Honestly through the issues keeps on increasing day by day.
Now it looks like my battery dies around the 60% mark. I guess my battery is uncalibrated?
Anyways, now because of these battery issues, I cant make it past 4 hours of use before the touch screens acts up and the phone shuts down.
I am very unhappy about this phone.
Any way to solve the battery issues?

I found out that this issue is most likely due to the battery. It somehow became slightly inflated, thus severely reducing the battery life and throwing off Android's Battery meter.
I tried over 6 different touchscreens and they all had this problem.
Great, I now have to buy a new battery as well.
And another issue is that when I restart my phone, the touch screen sometimes does not respond at first. It then starts working after a while. It could start working in 1 minute or it could start working in an hour. This particular issue only happens when I restart the phone

And there is no fix for this other than a full Touch+Display Panel replacement.
Right now I'm going to have to buy a cheap 10 dollar phone as my main phone, while I raise up the money and find the time needed to search for and buy these parts for my Nexus.
Honestly, Google and LG have made a very bad impression on me, and I will think twice before buying another LG Nexus phone in the future.

Update:
I Bought a new Display and a new LG Battery, and so far all my issues have been solved.
Now I guess I have to sell this off.
meh.

Sorry for the very late reply, but yes, It does seem that you will have to replace both.

To replace or not.....

I have posted in a few spots detailing my screen issue and I'm normally a very decisive person but this time I'm really on the fence and would like some input
About a week and half ago I began to notice a small red airbrush looking circle in the middle of my screen. It was centered left to right and favoring the bottom half of the screen. It appeared on dark backgrounds only. Over the next 12 hours it came and went, varying in intensity. Of course I researched it and found numerous accounts of a similar phenomenon where a blue dot was appearing on Moto X 2014 phone's and it was caused by blunt force to the screen or back of the phone. That couldn't possibly be my cause, it just didn't happen. I searched here for the Pure and found a single thread talking again about the "blue blemish" but that's it.
I immediately make up my mind it is not something I'm going to live with as I couldn't keep my eyes off of it. My wife, of course, said I was being to picky but she's lived with a dead pixel on her iPhone since it was brand new. So I don't respect her input here. Well I wake up the next day and it's gone. Totally gone. I tell myself maybe it was a fluke. Maybe I was too drunk and exaggerating things. I said F-it, I'll just let it ride. 8 days later, it reappeared first thing in the morning. I had a very busy day so the next time I picked up my phone around lunchtime it was gone and has not resurfaced. I called Motorola and they immediately offered a replacement which I agreed to and it's en route as we speak.
So here's the thing. I like this phone more than any other phone I've ever owned. I rooted it, I have it set up just like I want it and for the first time I am confident I'll use this phone for years instead of just months like I normally do. I just don't know how I feel taking a refurbished phone in its place. I normally don't balk at the idea but I had two bad LG G4's in a row with reception issues and now this Pure I'm considering trading in has a screen issue that is only around 1% of the time. If I return this one, it could easily pass the tests and get sent back out to someone else. Everything else about this phone is acceptable to me.
Would you take the refurbished one or keep this one? I still have the warranty in tact if the screen acts up worse down the road. I have to mail back the phone within 5 days so I'll have limited time to test it out.

Screen Burn-In

Wow. I didn't notice until today but the status bar icons and time are showing signs of screen burn-in. I didn't even know this was possible with LCD screens. I can clearly see them with a dark blue full screen wallpaper. This is absolutely horrible.

Not many believe so, but there's no problem getting burn-in on LCD. It's harder than OLED of course. Just look at the commercial LCD screens all over town and you'll see a lot of burn-in's...
The thing im baffeled over is that you managed to get burn-in on your phone. That means you have your screen on A LOT...

its display problem guys i had it 2 months ago..i showed it in service center nd got screen replacement since i had warranty.. u guys should do same if u have warranty and make sure to show them those pictures cause that problem doesn't always appear on screen.. sometimes it disappear..

Yeah, it's been ten hours guys. My phone's screen has been off for 9.5+ hours during this whole time. I can still see it.
It's also easy to spot when I pull the notification shade down. That's just... Horrible. I bought mine online so sending it for a replacement is out of the question. I can't live without a smartphone for a couple of weeks (minimum time with such grievances).

AFAIK lcd's don't truly get burn in but they persistence which should eventually fade. I'd imagine a defective screen is something acompletely different though.

It's usually ghosting on LCD. It should be reversible. Maybe play some movies or something.

This is kind of concerning and sad to hear. I traded my Nexus 6 for a G4 because I didn't want to deal with burn-in anymore (Moto X 2013 user). I hope I don't ever run into that problem or that the warranty covers it.

Same problem here... I just bought my G4 3 months ago...

i had sadly the same problem and made a tread http://forum.xda-developers.com/g4/help/screenburn-t3152109/post63428991#post63428991
Solved just by sending it back 2 my provider
(i had the device for 2 a 3 weeks) so i got i new one

Got to say, I've had my G4 since May 2015 and have no screen problems.

Just picked up a used LG G4 off Craigslist yesterday, guy had it for a month and was proven from Sprint themselves. Have been noticing screen burn or whatever you want to call it. Can notice it when you pull the notification panel down, and you can see a red tint.
This sucks lol! I'm trying to screen-burn tool off the playstore and will try it for the full 8 hours it says tonight and report back.

Bought my G4 June 05 of 2015. Keep the brightness at a steady 80%. No sign of burn in at all.
It bootlooped to Hell but no burn in.

SAME HERE!!!
It is possible with LCD though , I have SOny Xperia z2 before , but it never have such issue , so when i got my g4 and got this issue at first i thought it was a defective unit. So , i replace a panel under warranty , but then the problem appears again then i realized its the quality of the panel lg used. Lg need to fixed their panel really seriously as it happened since G3 .Now with the LG G5 having the always-on features i believe that the problem would be more serious as with 30 minutes non-stop screen on time with current G4 already appeared such issue, imagine always-on for G5.......

If you turn the phone off can you still see anything? If so it's definitely burn in or something like it. This is news to me, I thought LCDs were immune.

I got sensitive touchscreen problem, ghost touches, burn-in and now bootloop. Now to sent it repair, buy a new smartphone to wait it come back, get it back, see it's still not totally fixed, send it back again. This phone is **** ?
