[Q] Random screen rotation

Hey everyone, loving the tab so far just curious though if maybe mine has a issue that i will need to return in exhange for another. For some reason occasionally my tabs screen will rotate to portrait mode without me even rotating the device. This only happens once every couple of days. Just wondering if anyone else is seeing this and if this is a software or hardware bug?
Thanks.

You're not alone. Happens to mine from time to time also. Funny thing is it never seems to happen when I'm holding it but only when it is propped up in its case.

Yup, seeing it while sitting stationary in the Desktop Dock with Pandora playing. The desk/dock are not moving at all....so it must just be a software quirk than needs to be fixed.

Posted this a few days ago. Hope it is just software related?

It happened on my TF and previous 10.1. No worries. It's HC.

It happens to me when i prop it up in bed... No, not watching porn. Not that there is anything wrong with that if I were.

Nexus 7 Backlight Flicker?

Does anyone else have this problem with their nexus 7? I just got my nexus 7 today but I noticed that the backlight seems to flicker randomly
It doesn't look like much in the video but it is very noticeable and gets annoying when you're reading an ebook like i was.. Here's a video showing the problem.(It's near the end)
VIDEO LINK: h**p://db.tt/28eD0NLk (It happens around 9 second in) (change ** into tt)
For whatever reason this forum would not post a video link to show the problem.. for those who wants to know what it looks like please PM me..
But basically the screen flickers randomly ..
Is this a software problem? Should I go back and get it exchanged?

I don't see a video

I think its different.
Mine flickers no matter which app I use..even on home screen it flickers..
Also this forum has the most ridiculousspam prevention method..5 mins between posts + no link ? WTF

Its because you are new, we get a lot of trolls
Does increasing your brightness help?

I've had a similar problem as well. It seemed to happen to me on auto-brightness when it was changing the brightness level. I can't say for sure though, just my observation.

I havn't tried it yet..do we know if it's a hardware problem or software?
I just got it today so I can still return it if it turns out to be hardware

We really dunno at this point, but we are speculating software since both HTC One X and TF300 had similar problems and were fixed with firmware updates. Also someone switched it three times and all of them had this issue. Also try to run the screen in a pitch black room and tell me if the screen flicker is there. I may have a theory but need some other people to see if their units are behaving the same way as mine.

You can still post the link when you alter it a bit, insert a few *** into it, for example.

I turned mine on as soon as I got hold of it, no flicker, managed to go through and set up things, powered off and left to charged.
Coming back to it the screen would appear to turn on and off randomly, I thought it could be an app controlling a proximity sensor (I have one on my phone and I was EXTREMELY tired!), when I took it into the light there was no change.
I found that shaking it would help it flicker on and off at all intervals but didn't fix it. In the end I just started pushing random areas on the back, just before the issue went away I pressed around the bottom left quarter of mine and haven't had an issue since!
Glad I wasn't the only one with the problem though and would love to actually find out what it was.
Hope this helps!

Try this video,
h**p://dl.dropbox.com/u/13153603/Videos/VID_20120715_100253.mp4
it is using google map and you can see the constant flickering.. It doesn't look very severe in the video but it is actually very noticeable and annoying

I have the same issue with mine. It only seems noticeable when I have the brightness set to the lowest setting and on a page that is predominately white. I don't think it's the proximity sensor though, because it happens both when I set it manually to the lowest setting and when I'm in the dark and the tablet sets the brightness all the way down itself. Hope the next update fixed this, because it's really annoying!

Seems like only a small portion of nexus 7 owners are reporting this issue .. I think I'm going to return mine ...

I first noticed this flicker in a darkened room, so yes, it is definitely something going on. I'll try disabling auto-brightness to see if that matters.
If anyone else has info about this, please share!

I can attest that the flicker is ever present in a pitch black room as well.

Like this?
There are a few videos on youtube, but i cant post links but if you do a search you can find it

I noticed a flickering in chrome yesterday. But only in chrome and only while the page is rendering after it fully renders no more flickering.

Everyone turn off wifi and I guarantee it will go away. It happens when using wifi which makes it hard to believe that a software update can fix it.

intermittent lines on screen. hard or software?

hey,
I've noticed some lines showing up on my screen... they only show once every 10/15 min and run across the vritical when in landscape mode. typically only one or two pixels thick and lasts only a moment.
Like every one my tablet takes a tumble now and again, but if it was hardware then my is it so intermittent?
any ideas?

I think this has happened to mine too but it flashes so fast that I don't know if it's happening or I'm seeing things. It's very rare though for me.

I get it every now and again, seems to happen when the screen has been on for a long period.
Not sure what is causing it, I tried to Google it but couldn't find anything.

It seems to be software guys, as before the 4.1.2 update I was getting these lines around 2x as often. Hopefully the next ota knocks them out for good.

I think it is WiFi reception strength related. In my case, they appear only when WiFi signal is weak. They have been there since the beginning. But now, not only vertical, some times horizontal lines appear as well. Horizontal lines didn't exist before 4.1.2 update. Same issue have I with my TF700. So, I assume it's both hardware/software related.

I never had this with stock rom but have had it with some custom roms, I had it with "slimbean 2.7" but since updating to 2.8 it has gone. So, it points to software.
Maybe megamoz is onto something too.
I don't think it is a faulty screen. Something else is going on.

I am on rooted stock, had them both before and after rooting.
Don't think it is related to the WIFI, not for me anyway, as I get it when browsing in the living room and I sit right next to my router so I get full signal.

that would sound like a prime candidate for me. I have been stuck in hospital for 10 days, and the tab has been on for 15+ hours at a time some days... although the wifi angle is interesting too.
just happy its "normal" and not that I dropped it
thanks everyone for you input

Yeah I am also getting them and they seem to happen more when there is alot of white background on my screen or maybe that's when I notice them more lol but as far as problems go that's all my NEXUS7 has so hopefully it is software and can be fixed with a good old update COME ONNN 4.2 GOD BLESS YOU GUYS

I see it everytime I use Flipboard, and also have noticed it in Maxthon occasionally. At times it flickers, and others the thin line will stay until I move to another page/screen.
Sensation, ARHD667

its software. i remember seeing a post a while back about a guy who managed to take a screenshot of it. somehow. if it was a hardware issue, it wouldnt appear on a screenshot

Does anyone else have a misaligned touch screen?

Is anyone else having a slight misalignment on the touch screen?
For me touch is shifted about a millimeter or two to the right.
I've checked on both my N4 and my sister's N4 and both of us seem to be having this slight misalignment.
Both of us have REV 11 N4's. One was obtained through T-Mobile in January, the other was obtained through Google Play just last month.
I've checked on a few roms. I've tried CM, PA, and Stock with a multitude of different kernels (Franco, Faux, Trinity, CM, and stock).
To check:
1. Enable "Show touches" under the Developer menu.
2. Touch a part of the screen where you'll be able to see the touch bubble and hold it there.
3. Look at the screen at angle to see under your finger.
It's not a big deal, just something I've noticed when I had difficulty trying to use PIE on the left side of the screen. Although, I still would love to be able to get the screen recalibrated to have more accurate touch sensitivity to eliminate the difficulty that I have with CM's PIE.
Another question: Is anyone aware of any LG diagnostic tool to calibrate the screen? I remember back on the HTC sensation there was a file that you could load through HBOOT and get your screen calibrated from there.
Photo attached.

Oh wow I never noticed this , I have the same thing, never really had problems with it
Btw I have an older model , so its not just a Rev11 thing

Mine looks like its right on when I test. Maybe just a hair over to the right but nowhere near as far off as yours. Rev11 302K

I'm pretty sure you have OCD. So, take some medicine. Your phone is fine, stop crying. :crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::good:

Nope...

I thought I was just trippin when I noticed the same thing last week
Just tested and confirmed, pretty significant misalignment by about 1 cm, which is a LOT when you're talking about a <5" touch screen..
My next thought is, is this a software issue?
We need more people to test and confirm. But I believe that is what we will find. Software issue.
Anyone with a Nexus 7 on stock 4.2.2, please also test and report.

Wow never thought anyone else was experiencing this, mine seems to be off since I always have to touch a little higher than what I'm going for even nav bar.

Could not reproduce the issue on the Nexus 7. Looks like it's specific to the Nexus 4

I would think that it's a software issue. My HTC sensation was able to have it's screen recalibrated. I think LG would have some kind of tool to be able to do it.

Same exact issue here but I wouldn't even notice if I didn't try

[Q] Did i get a lemon.

So i am about 3 weeks into my LG G2 i went custom AOSP from the very start. never even touched stock. I had weird graphical glitches which i chalked up to the AOSP stuff. I also had weird touch screen issues. like double clicks when i was dragging my finger. I also had odd shaking. like if i would drag from one screen to the next and stop in the middle instead of the panes being static they would shake way way worse then i have even seen on a phone. after about 3 weeks it got to much. i went back to stock to see how it felt. i have the same graphics issues. and i think some of the same touch screen issues. Although i didn't stay long enough to really test, but the graphical glitches are there. I can reproduce anytime i want on AOSP or Stock.
Did i get a lemon?
I can post a video if anyone wants to see any of the symptoms.

What are the graphics and touch screen issues? Care to elaborate? I've had 3 g2s in about 2 weeks and have experienced the high pitched buzzing in the ear piece when making a call and the touch screen issues when the phone is used playing video or games after 45 minutes or so the touchscreen becomes erratic and the scrolling goes crazy. There's a couple videos on here showing the touchscreen issues when writing in a quick memo (looks like an EKG). Maybe a little more info on your part will give us a better idea on your problems though.

Why did you wait 3 weeks before you came to the conclusion you have a lemon? And with all those issues why you even asking that stupid question?
Sent from my LG-D801 using xda app-developers app

Sounds like 4.4 issues with the graphical stuff. Its common because we don't have a proper port yet.
I suggest you ALWAYS use your phone stock for a week or else you have no idea if its software or hardware when things go wrong.
I suggest you flash back to stock and waiting it out and see for yourself.

The touch screen issues are present in all G2s, it's whether or not a user "triggers" it that's the question. I've seen it in both AOSP and stock. So your touch screen is "fine." The other issues are not normal though.
Sent from my LG-G2 using Tapatalk

To conclude if anything is normal or no...you need to have your phone completely stock...What player911 said is the right thing to do.

So i swung by verizon and sure enough the demo model showed no signs of what my phone is doing...
btw i did say i went back to stock to test it and both the graphic issues and the touch screen issues have been present. I cant always reproduce the touch issues but the graphic glitches is some sore of faulty unit. I will try to get the to replace it on monday.

This is not true! I have the Verizon variant and I have no issues with the tough screen at all...ever?? In fact, for whatever reason (maybe because Verizon is more closed/careful/anal/controlling) I read of more issues with other carriers than I do with Verizon. So either it's Verizon, or maybe Verizon's version got a better batch of hardware while the others got a bad batch??? :crying:

Return it and get a new one. If you were at the store, I would have already done this. Its under warranty regardless.
Touchscreen is very responsive on mine. Maybe too sensitive. Sometimes I don't even feel my fingers touching the screen.
