Touch screen occasionally messed up

Hi,
I've got some weird problems with my N1. I searched around but couldn't find the solution.
I've tried CM7 stable 7.0.3 and Nighties 87 builds, and this problem happens to both.
1. When I'm running an app, such as "plants vs zombies", or typing with keyboard, when I touch a spot, it thinks I touch another spot. For example, when I touch key "D", it may give me a "space". When I try to place a plant on the left side, it puts it on the right side.
2. When I'm watching videos with MoboPlayer, the screen is locked sometimes (maybe this is a setting that I don't know, how do I turn this feature off?). When I press the "menu" button, it was supposed to unlock the screen, but it actually unlocks and locks back and forth continuely, and the phone keeps vibrating.
All the problems will be gone if I just lock the phone and unlock again. However, it will come back after a while.
Please help and thank you very much!
Andy

Yep, always been a problem with the Nexus One and often on capacitive touchscreens when plugged into a charger. You've stated the known workaround.

Really? Are you saying that these problems happen to all Nexus one and we all have to live with them?
By the way, I have these problems regardless if I'm charing or not.

Correct.

I see. Thanks.

Just turn off the screen then back on, it clears this bug and only takes a second.
All nexus ones have this issue.

I traveled from Singapore to the States for about 2 weeks in May and I suddenly had this issue too. I never had it for the 16 months I owned it back here in Singapore. And when I got back after my 2 weeks trip, the problem never occurred at all again.
I'm guessing that it has to do with either the temperature or humidity levels.

I agree with you. I think it has to do with humidity specifically because it happens only when I just left from the bathroom (taking a shower) and there is a vapor, then the touch gets crazy!

Iv'e only had it a few times in about 16 months. But, it's very dry here in Vegas wih very low humidity!

I've had this issue from day one with the nexus one. For me atleast it triggers everytime I have the phone plugged in and I'm using the phone at a 90 degree angle, like sideways in bed, very strange.

+1, always happens to me!
But never happened in other conditions.

This happens on mine too, but if the problem is the humidity, so why lock the screen and unlock it solves?

Were there any bears around? It could be the bears.

southern china. occurs occasionally also. yet not so often these days. more often when charging. it seems that temperature matters alot, not sure about humidity.

I have similar problems as mentioned irregularly, but sometimes switching the screen off and on doesn't fix it at all. It's not very humid where I live (except when it's raining). Has anyone else considered replacing the digitizer (the touchscreen panel) of the phone, and if this would fix the problem?

I sent my N1 back to HTC for warranty repair because of this issue. They did something and sent it back saying all good now. The issue occurs less frequently now but it is there.
I suspect there is something in the trackball area that generates EMF of certain qualities (frequency?) and it interferes with the screen circuitry due to poor shielding and close proximiy.

this is definitely a design flaw of N1, the touchscreen controller chip just SUCKS

Nexus 7 3G Defects - here!

Hello people!
As we all know the nexus 7 32gb 3G has shipped!, This is for everyone who has the Nexus 7 -3G- version only!
Do you have an issue with anything of your nexus 7 components (screen issues - build issues - speaker, etc ...) that are found on the previous builds of the nexus 7 non 3G ?
Did you guys find something that you like or you feel is better than the one with the previous build or non 3G (if you own a non 3G nexus)
like say, Faster, snppier, better graphics, performance etc ..
Sorry for my not so bad English

Just had 2 3Gs arrive to replace my old 16Gb wifis
Both perfect in every way, (Saying that so were my wifis)
Only comment is (Are google trying to get apple to sue them over the sim removal tool!!!)

Oh the reason Google are stating that Cases for the wifi nexus 7 are not compatible with the 3G version is that the Mic has moved due to the microsim slot so the flap on the cases covers trhe mic on the 3G version.

This seems a little pessimistic to me. Why assume they are going to have tons of defects? Won't google/asus have learned from the mistakes they made with the early wifis?

I didn't mean to be pessimistic at all .. just scared of that feeling when you wait so badly for that shiny device that you ever wanted but only to figure out that you have to sooooo lucky to get a (well-made) one without any defect !! I hate QC.

i see the need for this very much,
i just got the 32gb wifi only and maaaann.... the feel to the tab is just...different like the back panel feels...better i cant really explain it the unit feels heavier too.

Got mine this-morning. No defects at all. Why would you expect any? The Wifi version has been out for ages so any major defects would have been caught long ago by the early adopters.
The only "defect" per-se is deciding what the best deal on a SIM card is... 3 is probably the best network... but what one to order? All rather confusing for a poor old mouse brain.

I got mine last night. It has some backlight bleeding and also has these funky faded streaks (hard to explain) on a black screen these streaks give the blacks a washed out appearance. I compared it to my 16GB N7 which I got in Aug and I didn't notice these streaks but do have backlight bleeding on that one. I'm actually getting it replaced for these streaks but I've come to expect and even accept(as long as it's not horrible) backlight bleeding on Asus tablets. Having owned the TF101 (3 of them) the TF201(3 of them) and the infinity I have not came across a single one that didn't have some backlight bleeding to an extent or another. Some having it much worse while others maybe having just a small spot in the corner. But I honestly have not seen a single one (mine or a friend's) that didn't have backlight bleeding to some extent.

Mine has some very slight backlight bleeding, but nothing I'd complain about. Unfortunately, it does have the blown speaker issue...so an RMA replacement is on its way.

I bought a 2nd Nexus 7 3G version and all the issue of my 16gb WiFi are gone... The main problem the light flickering which is gone totally, also the screen is now flat with the bezel finally.
Sent from my Nexus 7 3G

Mine is fine overall. There seems to be some slight backlight bleeding on the left side of the screen, but not major enough to RMA.
Speaker sounds fine too as far as I can tell. The only "issue" I think I can report is that when my tablet has been sleeping for a long time, the mobile data will cut itself back on if it's off. At least the mobile data works though. Anyone else experience this?

I forgot to mention that I have noticed my screen flickering a bit when in 'auto', and depending on the ambient light. It's almost like the screen can't decide where to set itself and is bouncing between 'levels'. The problem seems to go away completely when I just turn off the auto lighting and keep it at minumum (which is how I usually use it). Is this the screen flickering problem everyone keeps talking about?

Just got my replacement an hour ago. Body creaks less, bezel appears slightly more even (although the old one was really even to begin with), and speaker sounds MUCH better. Only slight buzzing from the 'notification' volume bar, default tone, at max. Everything else sounds clear. I'll have to watch the screen to see about flicker. I have noticed it switching levels, but haven't noticed it flicker yet. It also appears to have less light bleeding. So far so good...

Ok guys - I need an opinion. I've had some time to play with my replacement N7, and noticed some odd things. I ran the battery down last night just to make sure it wasn't a dud - got about 10hrs of video (minimum brightness, sound down). It's not as good as my first one, but I don't consider it a dud. However, after it died, I plugged it in. A half hour later, I tried to power it on to collect the batter logs (simple battery logger), and it wouldn't power on. I pressed the power button for 5 sec each time, nothing. No white battery charging logo either...just unresponsive. I kept trying and it finally booted. I think I had to hold the button for 10-15 sec - and the battery was charging and at 10%. Never happened like that with my old one - just a consistent 4 second press to power on. Does this thing need 10% before it will power on? Reading the forums, the power on issue seems to be common. Should I be worried about this? Should I just keep my original unit even though the speakers are bad? I really don't want to end up in the endless replacement loop. Do others here have occasional power up glitches?

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...

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!

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.

[Q] [HELP] Digitizer vs some weird BUG ?

for the past week my screen has been going whacked out on me.
the on-screen buttons would start clicking on their own, and sometimes the screen becomes unresponsive,
BUT
when i turn it off, and back on, it would work perfectly fine .
so i basically get a 50/50 chance if the screen going crazy on me...
now if it was the Digitizer, wouldnt the problem be ALL THE TIME?
as opposed to being random, could it be a BUG ?
Can anyone please help or advice, thanks !

If a factory reset doesn't fix it it is probably hardware. I have seen intermittent problems with digitizers before.

I have a similar-sounding issue (on-screen buttons flashing wildly, et al.); I am thinking of opening the device to check on connection
Is it more or less likely, in your experience, that the connection between the display assembly and the board is loose from impact or whatever, or that the digitizer itself is just defective?
Thanks for your help.

I had the exact same problem on my device and it can be due to two reasons.
1. If your phone get extremely hot during use then the screen starts behaving abnormally.
2. If you had dropped your phone then there is a slight chance that you have damaged the digitizer.
I had the second problem and I have replaced the screen and it is working normally again.

annoying flickering and/or flashing

I'm having a very frustrating problem with my Nexus 7 (2013). About a week ago I started to notice the screen flickering and or flashing. I uploaded a video to show exactly what it's doing. I have tried to research and the only workarounds I found were to disable auto brightness and wi-fi optimization but both have been ineffective in solving the problem. The Nexus is currently running this kernel (razor-jss15q-factory) and was purchased around release day.

I have a flickering problem but it looks different than yours. Also my screen occasionally flashes black. I've also tried all the auto-brightness and WiFi tricks to no avail. The problem persists no matter what brightness my device is at and across multiple roms. I'm just about ready to send it back to ASUS for a replacement.

The flicker to black is not normal. Slight flicker at low brightness, more units have.

If JSS15Q or JSS15R doesn't fix it, I would return or exchange.

I returned the tablet to ASUS. After a 2 week turnaround time (including shipping both ways), I fired it up and immediately noticed the exact same problem (random flashing to black, plus some minor flickering). I called up ASUS again and inquired as to what they had "fixed". I was told by the customer service rep that they simply did a factory reset. They could offer no explanation why this was the only thing done.
So, back to ASUS it goes, again. This is frustrating.
