Should I RMA(multi touch problem)? - Nexus 7 Q&A, Help & Troubleshooting

For reading books it's fine, but I get 180 turns in Dead Trigger but I'm not sure it is related to that as discussed here http://forum.xda-developers.com/showthread.php?t=1789450
P.S I also have a slight cracking issue on the left side if I push to hard on it(no lifted screen problem).
From what I asked around almost everyone has this touch problem, so I don't know if it's a feature or a problem.

I got mine RMA'd and the replacement was flawless except for having this issue. I'm starting to think this is an overall design flaw of the Nexus 7.

You can try the lock unlock cycle. For me it fixes the issue until the next time. Which suggest it's a software fault. Returning it over and over is unlikely to fix anything.

Screen Re-Alignment every day?

It seems that as of late I have to re-align my screen almost on a daily basis. It will be ok vertically, but horizontally it seems that it's always shifting.
Has anyone else ran into this?
Yep, I've run into it. Sometimes it can go days without having to realign it, other times I have to realign it every 15 minutes. Seriously. I thought it might have something to do with opening and closing the keyboard but it's been hit and miss so far. I can't prove that it and I can't prove that it isn't. Sure would be nice to figure out what it is, however, and have it fixed.
How do you carry your phone around? Do you keep it in a case on a belt clip or do you keep it in a front pocket of your pants? If you do not use a case then try it for a few days and see if this helps with the alignment problem. (Body heat and/or pressure on the screen may cause the alignment to drift.)
This is a know hardware defect. It should be covered by your warrenty. T-Mobile exchanged mine with no problem.
Mine had the same issue but it hasnt been an issue since the 2.26 update on Tmo.
I had my phone replaced and it's still having the alignment issue. This sucks bad. Realigning and resets doesn't help!

Getting rid of magic button and vbar, if you run those apps, did the trick for me...I switched to wisbar desktop and ever since I have not had to realign my screen once in 2 months
I'm going to try this out and let everyone know. I'm having the terrible screen alignment problems (I at first thought that it was the keyboard and switching landscape mode) but I have magic button installed. Going to try the switch to wisbar lite and see if that helps. Does anyone know if the business card trick for the hermes will help with this?
I think it is a hardware defect, i have problems with mine, not only i have to re-align it often, my screen is also not responding to touch either. (from time to time).
Not to respond right away without extensive testing, but I did just put on wisbar lite and noticed a definite improvement in aligment (certainly seemed better than magic button) someone else should try this too and see if they notice an improvement.
I was having this issue for awhile. The card trick had helped on my previous 8125 but not this time. Carrying it in the case instead of my pocket seems to help quite a bit. The issue also seemed to be affected by pushing on the plastics around the screen so that might be a clue right there too.
align
delete
Sounds similar to my fix of pushing on the plastics all the way around. I haven't really had this problem since I did so and I have only had to realign it a couple of times in the last few weeks.
my phone's alignment used to get screwed up multiple times a day.
I took the stupid stick on screen protector off it though and haven't had that problem nearly as often. I maybe realign once a week, and when I do, it's only because it's off just a bit.
I had alignment problems frequently a few months ago but it is all history now.
1) Fix current alignment problem.
Just make sure you confirm if it is a hardware defect first, by checking the tiny gaps between the touchscreen and the casing for dust particles. Use a high power scope(I work in a semicon backend company so no problems getting one). Clean the gaps all around the touchscreen. See if that fixes your alignment problem. If it does, then probably your screen has some electronic problems(claim warranty).
2) Protect your screen from pressure at ALL times except when you use it with your stylus or finger.
I carry my Wizard in my pocket with a plastic transparent plate covering the entrie screen(ala HP's RW6828 forgot that model already).. Have been doing this since last year and no alignment required since last year...
Just wonder why HTC doesn't make it an option of have the protective screen on their devices... Beats having a bulky casing..
Permanent fix for Alignment problem in 10 seconds
Well I read many posts and finally came to the conclusion that the best and permanent fix for the alignment problem is as under.
Slide out the keyboard, you will find 2 screws at the back. Loosen them and then retighten them but not as hard as they originally were but lightly.
Presto
Problem solved.
U will never see your screen misalign again.
Thanks
software problem
The original Cingular wm5 rom had this alignment problem, I flashed NBD's WM6 v5.1 rom and it was fixed. I tried other wm6 roms with mixed results, some would get misaligned, others alignment stays perfect. Anyway the NBD rom just works, improves battery life, speed, I could go on all day.

Different manifestation of Screen Alignment issue

Hi, going through the emails on this list was indeed very useful. I bought an iMate JASJAM in January 2007 and it started giving me a weird problem with the screen.
The phone was working perfectly OK till Mid Feb when I started noticing that any application I opened (including phone or contacts) got closed automatically within a second. I observed carefully and saw that the 'X' on the top left corner of the screen was probably getting clicked on its own. I suspected it is most probably a screen problem and took it to the iMate service center. They promptly replaced the screen in 2 days.
It worked fine for 15 days before I am seeing the problem again. Could someone help me please. I am seriously dependent on email through my phone for my work. Would appreciate any sort of guidance, even if it seems obvious.
My JASJAM is 647XX s/n based
Thanks a ton,
Aditya Deshoande
If indeed the X is getting phantom taps, this is not a screen problem as such. In other words, you could replace the screen time and again and it would recur. The issue is that the screen gets pressre/pressed by the bezel around the screen. The screen is rather stupidly sensitive to touches even below the bezel. Pressure can arise from a slight twist in bezel, from heat expansion and from dust trapped between bezel and screen. You might try the "business card solution" - though it is not guaranteed.
I would also take a backup and do a hard reset. Try the problem apps without restoring the backup. This will identify whether it's software or the SA related problem.
f the problem is still there, I would demand a replacement not a fix, because if something is out of line it's not going to be fixed by swapping screens.
Mike
Thank you
Mike,
Thank you for posting a reply so quickly. I suspected it is not just a screen alignment issue the moment it appeared again. None of the fixes mentioned for the SA issue work. I just wanted to check if anyone has any suggestions to try something. There are no applications installed by me and I have tried hard reset. In fact the crosshair in the align screen application keeps moving without me touching the screen.
The problem is that this problem makes the phone useless because I cannot open the dialer. We need to be extremely careful of what iMate and HTC seem to be shipping out. This is a damn expensive phone to have such problems.
I will request for a replacement but would not be surprised if I am refused and told that it will be repaired since it is warranty.
Let us see if I need to drag them to consumer forum. I will, if the need arises.
Regards
Adi
Good luck Adi - I hope it works out. Yes that jumping around of the cross hairs does prove there is pressure being put on somewhere. Indeed HTC did appear to have largely resolved the SA and SA related problems - but I'm still seeing quite a few.
Cheers
Mike
Heats up during charging
Hi Mike,
Perhaps the problem is compounded by the fact that it really heats up if you charge the phone while it is still in the cover. The one with a belt clip that comes in the box
My screen does not respond to any taps anymore. Which in a way is good because I am at least able to call as well as send/receive emails.
Regards
Adi
Same problem here!
So my Hermes, which just got replaced by Cingular after the "red light..not charging problem" (Thanks for the pointers on that Mike!). But my new unit is also having phantom clicks on the x or in landscape the Start menu kept getting clicks. And I too got the moving crosshairs during screen alignment setup. Now the whole screen is whacked, not repsonding to any clicks.
Cingular are sending out another unit. I love my hermes, but seriously getting worried about the reliability of these units. I really can;t be without my unti working for too long, I'm stcuk having to go back to my SE P900 (with a flaky battery) or my SE S700 which sux.
It is a worry and very frustrating. However, when you get a good one it is well worth it. A hassle I know, but some folks here say they've been through 3/4 before being happy. This is the secret I think, put up with no physical defect and get an immediate replacement. Use a cheap mobile while you wait for the replacement. Most of the 'pain' comes from trying this and that and the other to get the device working and perhaps 6 out of ten times you fail. Use the warranty without hesitation. There ARE good ones out there!
My thought for today!!

Flaky Touchscreen (Just mine?)

I'm wondering if other users have experienced this. I find that after spending some time with the Transformer 300, especially when moving the machine on and off the keyboard dock, the screen will start to act flaky. In some cases what I'm seeing are "phantom touches." The home screens will start wobbling back and forth, as if someone is half-swiping them. In one case, I was playing the game "Sentinel 3" and the screen started zooming in and out as if someone were pinching it. That's with the tablet undocked. With the tablet docked, sometimes what I'll find is that the screen will become un-responsive. I'll click areas like the app drawer ad nothing will happen.
This is all resolved by shutting the machine down and bringing it back up again. This has happened to me numerous times, enough, in fact that I'm pretty convinced I'll have to take it back to Best Buy. My only question at this point is whether to return or exchange.
The fact that shutting it down fixes the issues suggests to me that it's a software glitch, which could potentially be fixed with a future patch. But that also means that exchanging the device likely won't do me any good.
So I'm posting this to get some feedback from the community and see if others are experiencing these same issues. If not, then maybe I got flaky hardware (a loose connector or something).

I agree it sounds like software since the reboot fixes it but your issue doesn't seem that common. I've seen a couple now that are somewhat similar but not like the pervasive left screen glitch. I would try an exchange personally.

Well sorry to burst the bubble but doing a reboot to resolve the problem doesn't really rule out a hardware issue. A hardware issue can be intermittent, there's nothing that states that it must be permanent. Furthermore it might not be the rebooting that resolves it but the time that passes. In other words, the problem might occur only at 6:45PM and last for 30 seconds, if you reboot it you might not experience it again. You have no time machine so there's no way for you to really figure out when it will occur and for how long to find out what's causing it.
It's all tricky. Some errors can occur both due to software and hardware so it's hard to determine which is actually causing it for a specific issue.
But a few things lead me to believe it's hardware.
1. Why aren't more people experiencing it? A software issue results in far greater people experiencing it, especially for a group as homogenous as TF300T owners who all own the same device. The conditions are already ripe and unless a third party app is causing it, everyone is running the same code and therefore more likely to experience the problem. A hardware fault would have to be deeply ingrained into the construction, the likelihood they had let it progress that far is unlikely. Instead, it seems like a QC issue which only affects a few individuals like you.
2. Touch screen issues have been noticed in not just this device but others. It can take on the habit of registering ghost input, no input, etcetera. Happens on the Nook Color too. Happens when the device is unplugged but mostly when it is plugged in to a power source especially the wall mains. If you're not getting it from your wall mains, it's probably the device. If it is your wall mains there's nothing you can do about it.
3. There's nothing random about handling touch screen events so I find it hard to believe this is caused by software. It's more likely it's a bad touch screen feeding false events to good touch event code. The likelihood code is doing this and doing this where only you experience it and not many others (actually I've seen no other people complain about this for the TF300T and two other people complain about it for the TF101) is really low.
IMO: Just exchange it. If you make the mistake of never exchanging it you'll be stuck on that boat forever. It's probably poor QC. If the second one has the issue, that bumps up the likelihood it's a software issue as these issues in hardware are very rare and I don't think two possible units experiencing it is very common unless it was a far more common software issue. If it occurred again I would either exchange it again or get a refund.
So yesterday I flexed the screen (basically pushed up ay the back, center with my fingers and down at thes sides with my thumbs) and the tablet started bounging between the home screen and the app tray at regular, 1/2 second intervals. back and forth, back and forth.
I also discovered that if I hold the tablet in portrait mode with my left thumb about 1/3 of the way up and sqeeze, the screen becomes completely un-responsive. if I ease up the pressure, it registers touches. I discovered this by readong a post by another user that had the issue (though I think in his case his screen would go haywire).
So I'm definitely taking this back to the store. The only question is whether its an exchange or a refund. I absolutely love the concept of this tagblet, and when it works its glorious. So if I can find one that doesn't suffer from these issues I'd love to hold on to it.
Check the running apps it's most likely mem related
Hi,
I've had two of these for about a week now, one for my self, and one for my 10 year old. I had to go into settings and shut off all kinds of stuff that was attempting to auto updated right off the bat. These don't come with a ton of memory right out of the box.
If you press on the bottom left corner of your screen the two little squares, it will show you what is loaded in memory. Every thing that comes up on that list on the left hand side is a opened application that is actively eating up your memory.
The only way to clear these apps once opened is to power the unit off, and then back on.
On both mine and my sons, I shut off all the auto updates, there are a bunch of different settings, you really need to go through them and look too many to list but a bunch should be turned off.
I don't have any issues at this point, neither does my 10 year old, he's always playing games like Fruit Ninja and normally has three or 4 youtube windows in the back going with in 5 minutes of turning the thing on and no issues.
Mine I use more for business related stuff, and also no issues. However right out of the box the first day it was a bit flaky. They both run smooth now.
I'm just waiting on some one to give me a root app for .26 since the second I turned these both on they updated the OTA firmware which took them off .17
Anyway I hope this helps.
Good luck.

Sorry didn't see the post about issues with where you pressed the screen. That one sounds like you may need to take it back in to have serviced. I tried what you said with squeezing the screen, and pressing the back in different spots. Nope, no issues like that. I would say it requires service.

The button you refer to in the bottom left is the multi-tasking button. If you press it and swipe an app, it will be removed from that list. Android usually runs fine with lots of apps sitting in ram. The only real exception to this is apps that are poorly coded and will try to run in the background all the time.
If you want root look in the development section, there is a simple utility to let you downgrade to .17, root, voodoo backup, update, and restore.
I have same/similar problem see other thread

See here for my symptoms.
So, last night I took the tablet back to Best Buy and exchanged it (actually, had to drive to a second Best Buy because the one where I bought mine was sold out!). So far so good. Though I've only had the replacement a short time, I'm feeling good about this one. No hiccups so far. And upon running the initial setup I remembered that even during the initial setup of my first one, the screen had become unresponsive once. All in all I've got a good feeling about this one. And I do desperately want it to work because, man, I love the concept and execution of this thing.
Have you tried the creaky test with the new one to see if it's a manufacturing issue indicative of all TF300T's or whether it was just an isolated QC incident?

unresponsive touchscreen?

My nexus 7 currently has an unresponsive touchscreen. Almost none of my touches are working now and yesterday the tablet was working just fine but some of the touches were not working. Now almost all the touches arent working, did the hardware just fail on me?

Here is what I posted yesterday on another thread, but short answer is that yes it's most probably hardware fault (I don't have picture at work, so can't attach it here).
I purchased my Nexus 7 from Staples during business trip to San Francisco. My device started having touch screen issues after few hours. Factory reset did fix it and I liked the device a lot so I didn't return it as I thought touch screen issue was just a SW glitch. Issue came back at the airport . Unfortunately I didn't have time to return the device at that point. Issue wasn't manifesting itself all the time, but seemed to come up every time I plugged the device in charger. Symptoms were exactly as in this video: http://www.youtube.com/watch?v=uVkvCXDKU2M and the other one in which multitouch is demonstrated. I suspected different applications as a reason to the problem as well as faulty charger. Then I found this thread and became assured that this must be a HW problem.
As I'm living in Finland and don't know when my next business trip to USA will take place I decided to try and fix the problem myself. I took off the back cover and touch screen worked perfectly. Initially I suspected grounding problem but pretty soon came to conclusion that it can not be the case. The problem in my case was the "sponge" pushing (what I assume is) display / touch flex. I have marked that in the attached picture. Even a very light touch to sponge caused touch screen to go crazy. As I don't have the luxury of immediate warranty repair I decided to remove the sponge and my Nexus 7 has been working flawlessly ever since. I can even charge and everything works as expected. When I started charging the device I placed my Nexus 7 on the table. It probably caused slightly increased pressure on back cover and therefore to "sponge". After removing the sponge I can't see any of the touch screen problems I was having. Couldn't be happier as I don't have any of the other problems people have found and device is working as it should, at least for now.
I don't encourage anyone to do what I did, but if you are in the same situation as I was with imported device, you can try to take off back cover and see if the problems are fixed. You should be very careful though not to break the device especially when it's powered on with back cover off. Hope this helps someone.
EDIT: 22.8.2012. Forgot to mention, that turn of WiFi if using device with back cover off. Turning off NFC and GPS won't hurt, although GPS is receiving only. Reason is that antennas are located on back cover.

Galaxy S7 Edge strange behavior, Random touch input

Hello folks,
I've googled a lot but maybe I used the wrong terms or it's a rare problem. But my phone has a small annoying bug. The bug I'm facing was always there but after the latest update it occurs much more.
Most of the time it happens when you unlock the phone and start typing. In the video below you can see the problem.
Sometimes the recent apps and back button refuse to work while this happens. Not always.
Is there anyone else that suffers from this strange behabior?
I allready tried to remove the TPU case but that didn't solved the problem.

the solution is simple,just make sure ur fingers aren't wet!
Over a period of time (if you looked at your phone at an angle with the light reflecting off) the Gorilla Glass the phone needs to be wiped down, preferably with a micro-cloth (the same type you use on glasses). The oils on your hand, combined with sweat/water, can do freaky things with the touchscreen.
I have been using a stylus most of the time to type and interact with my S7E phone. Not only that I like it better I find it with my big fingers I am more accurate when I am typing and interacting with the phone.
But do not forget this S7E is completely covered with Gorilla Glass and needs to be cleaned like all other types of glass does...good luck.
Cheers!

The exact same thing is happening in my case (atleast has become more pronounced since the latest update), the recent apps & back button become unresponsive after you unlock the phone and there are random ghost touches. The problem seems to normalise after you lock & unlock the phone using the power button. Any insight on the same would be helpful.
I cleaned the phone multiple times. Actually I clean it every day.
As arun.subrm says. It goes away when you lock and unlock the phone.
Very strange. Actually it gets worse after every update. Today it happened over 3 times in 4 hours. Rediculous and very annoying. It makes it an unreliable product this way. You don't know when it will happen.
Still waiting for that moment when I accidentally buy a living room couch on ebay or something xD.
