Screen transitions.. - Nexus 7 Q&A, Help & Troubleshooting

Hi I was wondering if any of you guys have the same problem.. I'm just on a stock rooted 4.1.1 ROM and everything is good and fast but, one thing i noticed is that when scrolling from left to right on the drawer or home screen sometimes it would be snappy but at times it would have a slow transition (although smooth) it would take its time going into place.. not sure how else to explain it. (Kinda like the elastic band effect but slow at coming back)
Is there a way to fix this?

Unresponsive touchscreen on some points.

After using the new SGTab 2 7" I have experiencing the touchscreen is unresponsive in some occasions.
For example closing the tabs in the brrowser on the X mark is very hard, both in the stock browser and Chrome.
When I try to clear my mssage in the bottom right corner, it also doesn't recognize my touch on various occasions.
It seems to me that along the edges of the screen, the touches are harder to recognize. Have any of you recognized this problem aswell?
After reading a review on Techradar.com, this passage stood out for me:
''Disappointingly, we found the touchscreen experience to be a little sub-par. The sensitivity of the display was lower than we expected, and we found it hard to register presses on small parts of the browser, such as links, and the close tab button.''

I encountered the same fault/defect on my Tab2 10.1
especially on small objects,
but it seems not to be constant.
meaning it generally works, but sometime i have to press multiple times to activate the selected button or object.
I found that fingerprints really lower the sensitivity of the screen. If you wipe off the screen after prolonged use, the touch experience will be much better. I verified this using a touch recognition program.

Yeah I wipe and I wipe haha..on all my devices. But it seems worse on this device, compared to all others even though I clean very often.
Cheers for your suggestion though

thats true
some times happens to me too in youte app, i notice it only there still.
Same thing here, it gets incredibly frustrating for me. It's very noticeable trying to close a tab.

Got mine today. And ive been fine, then again i have a crappy screen protector lol.
After rooting and flash a custom rom on p5100, everything is OK. Become responsive. So I believe Samsung touchwiz on ics might be the cause of the problem.
Yeah me too not satisfied with the samsung touch wiz...but I don't think I am having problem with touch screen...though it is not as smooth as with iPhone 4...

Do you have a screen protector on? Mine was crappy with it on, so i removed it.

Had this problem when I was on Stock. Not dead touch points but it was more like an inability to sense my touch due to lag due to touchwiz. Changing to nova launcher helped... And then.... Tried CM9 rom and all is well. Not sure if you wanna take that route but for me... It worked. I am a happy camper!

Is there a way to calibrate the screen on the T2 10.1?
After 10 minutes of reckless racing 2, the screen gets unresponsive, i think it might be something to do with the battery or cpu getting hot, I am using the stock modified rom from metallice

Lag through homescreens

Is anyone facing a little bit of lag when moving between homescreens on their nexus 7?
Only when coming out of a reboot but that's normal, otherwise I have no lag at all.
Sent from my Nexus 7 using Tapatalk 2
Some live wallpapers cause lag, their fault though. If you're lagging a quad core device you're doing something wrong.

Are your home screens cluttered with widgets and shortcuts?

No lagging whatsoever here. Unlocked. Rooted. Stock ROM.

i had lag with the screen rotation control but removed that and tis grand... i have a little while my weather/clock widget loads.. but its ok..
Ya I experience lag. Usually happens when leaving an app and going back to the home screen. Can be pretty bad lag at times
Sent from my Nexus 7 using Tapatalk 2
I've got several widgets on my homescreens and no lag.
With the stock launcher it seems that there is a micro stutter but that is only with stock launcher. Does rooting help lag on the homescreen? Because I haven't rooted yet.

Rooting itself will have no effect on it. Maybe a custom ROM or kernel though.
Well custom ROMS have done wonders to me.

There is a bit of stutter scrolling through the homescreens, its not totally fluid. I noticed the same with the Tegra One X as well (but thats ICS so expected).
My Galaxy Nexus on the otherhand, is perfectly slick and smooth. It's strange, it doesn't happen all of the time neither.
In the app tray too I feel like there is a slight slutter or delay if the finger stroke isn't long enough (even though it still changes screen).

So it might be tegra 3 thing after all? So only customs ROM could help this or another launcher.

Nova launcher with the "slide" transition is noticeably smoother than the stock launcher in my experience..

Night clock & burn-in concern

Hey guys,
I decided that I want to have a simple clock app running at night when my N7 is plugged in. I searched the market and found a lot of options; some with some cool features like "shake or tap to read time" and some with a flashlight built in.
Anyway, do I need to be concerned about "burn-in" with the Nexus 7's screen? (I didn't see any apps where the time bounced around like an old school screensaver on a CRT monitor!) I'm guessing this just isn't an issue with these screens, but I wanted to make sure.
Finally, does anybody have an app they like for this? Or a specific feature to look for?
Thanks!
Billy

I'm happy using the regular clock. It works I landscape, and when you touch the screen, it dims down.

BEWARE !! I just found a burn-in on my screen because of this, and I still don't know if it's going or staying ... damn defects !

Background App shadow on Nexus 7 screen ?

Hello,
I have a Nexus 7 32GB WiFi, using 4.2.2 stock ROM, rooted and unlocked boot loader. I wiped device when 4.2.2 was released and started fresh again.
For a few weeks now I have noticed when using Chrome browser after closing or letting browser run in background when looking at my home screen I can see part of the browser like a shadow showing on the screen.
Here is a picture of it, does anyone know what this is and is it a hardware problem or something ?
Some times the shadow is much noticeable than other times.
If you look carefully you will see the shadow.
Thanks for any help.

Not a hardware problem. It goes by a couple of terms, ghosting, persistence, and if permanent screen burn-in.
It happens when you have the same screen up for a long time. If it fades, It's persistence, and does no real harm. If the 'ghost' does not fade it's burn-in, and is permanent damage.
Keeping your seen at the lowest brightness that suits your current need will minimize this, and help prevent actual burn-in.

Touch Screen Issues!

Is anyone having issues with the LG G2 touch screen.
The things I'm noticing is
guesture typing it loses it's trail and begins a new word. So if I'm trying to spell "Think," it'll get the "TH" then space it out and get some other string of letters etc.
Web Browsing; it'll click a link I'm not trying to
Zooming in on photos and scrolling while it's zoomed it'll sparatically zoom out or move to the next pic
There's several other things that I can't seem to get to replicate! Anyway with my research here's what I came up with.
My issue is much like this but far less easy to replicate!!! And not nearly as bad. How ever I was able to do it when my phone started having symptoms I pulled up the note pad and it did exactly like this just way less significant.

Here's another forum with people going through issues!
I'll take that as a no
I was having issues like that with gesture typing on both swift and stock keyboards. Basically it would just add all kinds of random entries. In another thread someone suggested using a microfiber cloth on the screen. It seems to be working now.

Just noticed that mine does the same thing... But it's not consistent, only happens once in a while. After I reboot it's fine. Really weird.
I posted earlier, looks like it didn't make it up. I had same issue, I tried flashing back to stock, assuming I had done something with rooting it, tried making sure that it was not an issue with ram bring to low, nothing fixed it. Took phone back to att, replaced it, havent had the issue once since then. I'm rooted, flashed and modded work no I'll effects. If you are within your return period, I would suggest that you return.

Cool I'm glad there's some good ones out there. As soon as my replacement Zagg Symphony Dry comes in I will switch out phones.

Well I have seen some quality control issues with these phones for sure... I'm still on stock and not rooted and mine does this. Going to have to go by the Verizon store Monday and get a new one.

I made a video to help illustrate what's going on!
Well I got a replacement phone and the problem is still happening. So I went into the shed grabbed my old Cyanogenmod MyTouch 3G and I plan to use that until the Nexus 5 comes out. Hopefully I'll get a launch unit.
Just holding this little phone makes me feel all nostalgic lol. I bought it in 2009 and it still holds a decent charge.

Are you just going to wait until the nexus 5 comes out and then take your g2 back, tell them that this is the second one that has done this, and demand they replace it with the "newer g2" ie Nexus 5? I thought about this!
I'm hoping this is a software issue..mine is really annoying
