Odd random artifacts/render errors on screen - G Tablet General

Ok every now and then, I get random artifacts on the screen in the form of white lines about a quarter inch long. Usually around the edge of the screen, but occasionally even in the middle areas, it seems to happen mostly when moving to the homescreen from an app, usually a dark colored one. (Could just be me, and it is just random with no dependence on any conditions of color) It did definitely seem worse when using launcher pro.
Is anyone else having this happen or is this a sign of a bad screen or other part?
I'm hoping this is just render errors due to the newness of the tetra chip on android.

Other than the limited viewing angles, I've not had any issues with my screen. What ROM & launcher are you running?

This happens to me on every TnT build, and not on zPad. It doesn't happen often but I assume it's a bug with the TnT skin.

Running on tnt lite 2.0
Just grabbed up a second gtab, will test it out as well.

I'm seeing white horizontal lines too. TnT lite 2.0.0

I see this as well. I thought it was LauncherPro because I didn't see them with the stock interface or ADW.

It might be the Tegra OpenGL update in TnT Lite 2.0.0+, assuming that's what everyone is using. That driver was added mainly for Angry Birds, but perhaps there's some instability in there.

I am having issues with blank notifications appearing and being unable to clear them without a reboot. I've tried turning off notifications in ADW.

Yeah, I get them on zpad and assume they are from Launcher Pro.

Sounds as if this is a universal "defect" if this is happening with different ROMs and launchers. I've also noticed when I get the ghost notifications, I can't use the keyboard to enter anything, either. It just doesn't appear.

it happens to me all the time in the top edge of the screen, expecially around the taptap icon
It did happen in the old home screen app, BUT they actually reset the whole display up top if you watch closely (load the homescreen app and these artifact go away)
But I've only ever seen them at the top edge, so i always assumed it was a problem w/ their notification bar not updating the display properly.
I also noticed it doesn't seem to happen if the sound is dead ("obtainBuffer timed out" BS) - so perhaps the two issues are related (perhaps some memory issue w/ them writing to the wrong address, which is why the sound dies randomly, expecially if the display is off, it's clearly a driver issue)

If I remember correctly, this happened before the update on the prior TnT lite as well.

touchscreen questions

Can anyone who has installed a custom android type rom let me know if the touchscreen is better once rooted and reflashed. I am talking about sensitivity at the store two different ones now both units are just bad when trying to select something I occasionally had to hit the selection more than 2 times.
I am also interested in if this changes. I read that its hit or miss whether or not thr screen works as intended or has problems, leaving me to believe its a production consistancy issue.
Some love it and some hate it.
Does this sound accurate?

Sounds like it.
There's another thread about this which has a youtube video of one of the ones who said their's was bad and it certainly looked to be the case. In the video on the "home" "page" of the launcher when he swiped in the top half of the screen nothing happened most of the time, while it worked as expected in the bottom half. Mine behaves as expected wherever I swipe...
I'm not going to let on that it will be perfect, but when I moved to TnT Lite (I'm now on 2.2.1), I installed LauncherPro. Within LauncherPro, you can adjust the sensitivity and scroll settings that covers all the launched actions. Also, there's an entry you can add to the local.prop [go into adb shell and type: echo ro.HOME_APP_ADJ=1 >> /data/local.prop ] (requires r/w permissions to update). This change made it smoother (and quicker) to go from screen to screen.
There are still times where I press an icon and nothing happens for a second or so, but it rarely happens anymore with all the improvements that have been added to TnT Lite over the last couple of weeks.
I have had no touchscreen sensitivity issues to speak of with ZPad ROM. I am now running the VEGAn ROM which has really come together nicely in the last few days, and again the touchscreen is as sensitive in all places as I would expect it to be.
Any slowness/lag issues were resolved with the updated drivers that were discovered a week or two ago.
The stock TNT ROM has lots of software issues that are totally unrelated to the hardware. This is most likely one of them. I can't say for sure, since I wiped my unit within 5 minutes of opening the box and installed ZPad.
The touchscreen is still not as good with multitouch as it should be, which I believe is a driver issue, so pinch and zoom and similar multitouch action is not as smooth as it ought to be. But in general use, typing, swiping, scrolling, etc. I am just single-touching and everything works as smoothly and well as it does on my Nexus One phone.

[Q] Issues with standard android apps & games on Xoom - Any Solutions?

Hello,
I have noticed on certain standard android apps a number of issues that I have come across. I have tried with auto-rotation on and off of screen in settings. I have restarted my Xoom also. I don't have any of these issues with any of the tablet apps.
1. First off Jetcar Stunts, and Return Zero the menus are normal and function fine, but when you go into a race the screen looks like it is tilted at 45 degree angle. If you turn your Xoom vertical, the screen will level out, but you are looking at the car on the left side of the screen.
2. Several racing games TurboFly 3d and couple of others I cant think off of the top of my head work fine and the screen is in the right position, but to when you tilt to the left it turns the car to right, and vise verse the other way. The turning controls have been switched.
3. Adao File Manager, Adao Uninstaller, ishoot, and Medieval Castle retain their original size of an android phone. Is there any way to zoom in or have these apps stretched to fit the screen? The ipad lets you view iphone apps standard size and stretched size.
Anybody experiencing these problems, or have any solutions?
Thank you for your input.

Install "Spare Parts" free from the market.. Open it and uncheck the box for compatibility mode... Might not fix every issue as some things just refuse to run on HoneyComb yet but it should fix some of them. It will absolutely fix your last section where the apps don't fill the screen.
The problem is not you, or anything you did. The issue is honeycomb. Not all apps are compatable yet. It was like trying to run a win xp app on win 7 when it first dropped. Didnt work. Just wait. They will be updated eventually.
Thank you,
The spare parts helped with the apps that was stuck in their native resolution. It now fills the whole screen.
Yep... I'm waiting, too... seems Napster, SiriusXM, and my banks' apps aren't even showing up as installable on my Xoom - but they all show up on my Pure running XDAndroid! (waiting for July so I can upgrade to a real Android phone ).
I immediately put this all down to the fact that Honeycomb is so new, the devs didn't have opportunity to build versions compatible with it... yet.
But... this begs a question... I'd love to be able to copy the .apk's from apps I directly-installed on my XDAndroid port, onto the Xoom and see if they'll run anyway... but I can't seem to find the apk's. Being a noob on Android still, can anyone tell me how I can get a hold of these app files, or does the Market simply download, install, and delete?
Thanks...

Acer A510 help

Hi All,
I recently got the acer A510 overall i am happy with it except i have a few problems and wanted to know if anyone else is having the same.
I noticed a fair few apps are unstable. The store shows the apps are compatable etc but they crash a fair bit.
While i am not too fussed by it 1 does really annoy me.
It happens in both the built in web browser and on chrome.
Basically i can be on 1 tab and go back to another tab, but then it can't remember and starts to reload the tab (this is all in a matter of minutes)
Then after doing this a few times it stops loading. if i exit out and go back in all i get is a messed up black screen with bits of the app showing.
I have to reboot to resolve.
I have tried factory resetting and it's the same issue, all i did was sign up gmail and only download chrome. They both do the same thing.
Any comments on being a common issue or what i should try would be great.
Other than that the tab runs great plays movies great and is smooth very smooth.
I have the AUS version updated and theres only the 1 firmware. BTW acer are pretty useless in tech support area lol
Hi malos1984,
I have also issues with Chrome. Sometimes Chrome just freezes from time to time and the tab reboots. More often the page gets white and blinks (seems it tries to refresh but i gets white again). In this case I am able the restart Chrome.
It was so annoying – so now I am using Dolphin and I am quite happy. No freeze no reboots. Everything works fine.
It seems that more people have the same issue with Chrome on the A510. At least if you go through some of the play store comments…
Perhaps there will be a fix coming. Not sure if this needs to be fixed on the Acer side or on the Chrome side.
Cheers,
Elendiir
I tried Chrome, didn't like it and just switched back to stock. That browser has all my needs in it.
But I totally agree with the OP, Acer doesn't have the sharpest tech support. lol.

Lol no they do not they don't even have an email contact here in aus pretty bad for a tech company.
Back on topic.
The strange thing is the default one is buggy too very similar issue.
On top of that embedded YouTube videos on sites and forums show the videos overlapping each other in the top left hand of page in both orientations and a black box where they should be displaying on the page.
I hope we get 4.0.4 and jelly bean later on as a update.
Another question I had is why doesn't shadow gun work I stupidly paid for it but its delayed in responsiveness.
I.e. i press a menu button and about a minute later the menu opens, then in game I tell it to do something and it takes about 3 secs to do that.

Ya I hope we get JB soon. I could use with the tab being a little slicker. Overall things are very smooth compared to HC but pale in comparison to the iPad.
Btw, SHadowgun on the A510 sucks. See a threa here in Madfinger's forum. Lotsa people facing it yet they're not gonna do anything about it. That sucks! Link: http://www.madfingergames.com/forum/viewtopic.php?f=17&t=525
hmm
I agree with the stock browser stability.. It seems to refresh whenever I change tab n back to the previous tab.. and sometimes when I am multi tasking, switching back to browser gives me a white blank page. I have to scroll back to the top then the page shows back.. WEIRD.

I faced the same issue on my tab playing shadowgun. however, after switching from 1.044 to 1.073, the problem have disappeared, but now I'm facing with problem of screen responsiveness while putting it on a table. they said its grounding issue and can be fixed from the settings, which have to be done every restart.(which I did not face it on 1.044).

Ok, I'm a noob at this but what's 1.044 and 1.073? I'm unrooted btw. Anyways, yeah the tab has got pretty bad responsiveness all around and you're right, when you put it on a table (flat surface) its totally unusable. Why is this so?

I do have problems with Chrome on the A510....I will probably try dolphin to see how it goes.. I hope acer releases an update soon cause I hate having that bloatware, including the AcerNidus app, which is supposed to collect information about bugs....well what for if they don't release updates to fix them?

If you go to about tablet, you should see a "software version" field. 1.073 is the latest.
I actually have my tablet sent back to warranty service since the gyroscope is miscalibrated. I'm supposed to get it back after a week.
As for the non-responsiveness, it is a bug that was introduced in the latest firmware updated. To fix it, you'll need to go to display >> screen responsiveness >> toggle it to low/medium, then high again. You need to do this right after every restart.

Occasional app transition flicker since Pie

I have a Pixel 2 and I feel like ever since the device upgraded to Pie I get this random horizontal line that briefly flickers during a transition between apps from the launcher. It is the very bottom of the screen for any app that keeps a black navigation bar at the bottom. It will only flash or flicker once and doesn't happen all the time. The main app that does this is Hangouts but occasionally happens with others too like the camera app or Google News. I figured it might be software but wanted to see if anyone else noticed it. The device runs fine otherwise so hopefully not a big deal down the road if there is failing hardware.

Screen dimming after 4-5 seconds

Hey all! I recently updated from Android 10 to Android 11 OOS 11.0.2.2 and I have a strange issue I didn't have before. On grey/blue backgrounds, the screen dims and changes color a little bit after not touching it for 4-5 seconds. I already submitted a bug report but I just wanted to see if others are having this issue. I do have a T Mobile device that's been converted to global, but again this issue wasn't present before. I can't report as to whether the issue happened on OOS updates previous because I just updated and got 11.0.2.2. I've also linked a short video here showing the issue. If you guys have any input at all, it's appreciated!
I may be having a similar issue. I am trying to view your video to see if it is the same problem. I have noticed that my color turns warm, as if the blue light filter was activated. It normally happens when I am trying to type in a field. In most situations, it happens when there is a lot of white being displayed.
I did not pay attention to the browser that I was using. It may be a Chrome issue, but that is only if we are experiencing the same thing.
Ok, so we are talking about two different things. But, your dim is very subtle, at lease as far as the camera is concerned. Does mine do the same thing? No idea. I probably never noticed.
However, are you using Adaptive Brightness or manual brightness? In my experience, OOS 11 came with a LOT of bugs. I've been getting screen orientation problems as of late, and it would lock my screen sideways depending on what I am doing. I do not use auto rotate, and I am certain that I didn't press the rotation button in the bottom right corner. Even if it showed up, it shouldn't have, as I was using my phone in portrait mode every time that bug showed up.
TL;DR: OOS 11 - YMMV.

So I have the same thing with the screen going super warm on white backgrounds too, primarily on web browsers. With the other issue it only happens with the brightness between 30-70% or so and the screen gets darker and the gamut seems to get a tad cooler but I've chalked these up to separate issues. No phone is without faults but it seems like Oneplus releases software without testing it at all.
Edit: I noticed the yellowing on Chrome, and nowhere else on the phone. Samsung internet does have the same issue
Yes, I have a slew of issues with Android 11. My problem is the fact that I like it a lot more than A10 w/OOS, sooo....I have no option but to tolerate them for the moment.
