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.

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.

Notified the same thing while playing Draw Something, I thought I was mad
Tapalked with my iNexus 4S

Nobody tested a Nexus 7 yet?
I'll test my wife's when I get home and post the results

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.

horrible UI lag with Samsung theme

Hello, I have been playing with my new S7 edge a couple hours now and am liking it in some ways and wondering why the heck I paid 2.5x as much as I did for my 1+1 in many others. This maybe be a small thing, but I'm on the fence about returning the thing and going with a 6P instead, so hopefully some kind soul will help me confirm if my problem is my device or some software thing.
So, it seems that using any of the themes from the Samsung Store that contain an animated lockscreen totally bugger the S7. Here are steps to reproduce:
1) Go to the baked-in Samsung store, it's a Galaxy Essentials widget 2 screens over on mine
2) Choose Theme Store at the bottom, then AoD themes. Pick one with an animated lockscreen (Night Sky AOD and PixelQuest_AOD are two)
3) Download one and apply it. Lock phone and attempt to enter a pin.
At this point, my phone becomes almost unusably laggy - the only way I can get in is with the fingerprint sensor, and that even lags. Again, while this may not be a huge deal, it blows my mind that this $800 phone can't handle these 10 frame animations, especially since I was able to do similar on the 1+1 quite easily.
Thanks for any words of advice or confirmation on if this is a wider issue than just my phone. note the issue is gone after reverting to the stock theme, which wouldnt be a problem if I didnt hate the brightness - even the settings menus are much more readable to me with one of the themes I mentioned, other stuff aside.

I have shineblack AOD, it lagged exactly as you described. Then I turned off aod and it no longer lags. Well it still lags in Chrome but that's another story.

Hmm, so the lag goes away without AoD? Great, thank you - must just be a software bug they will (hopefully) correct soon then.
Edit: tried switching off AoD in display, still the same lag.. guess you meant switching off the theme

Don't know what I am doing wrong or right lol but my phone didn't lag at all. I tried night sky and pixel quest.

Well.. that's depressing then Thanks for the result though. The phone I got is a Snapdragon. It feels like it's struggling in several other ways to me - ie, install bars going to 80% and sticking there forever, phone gets warmer than my 1+1 ever did running emulators etc just sitting on the homescreen, etc. This lagginess seems portentious enough that if others respond like you, I will just return and swap for a 6p. So yeah, thanks again

Well I have the Snapdragon too so don't know what's going on. Bit I'm on T-Mobile so don't know if it will differ per carriers. But it does seem like you are someone that like pure vanilla Android and if that's the case yeah you might want to get the Nexus phone.
Sent from my SM-G935T using Tapatalk

No I still have the theme on. It was lagging when AND was on, but since I turned AOD off pressing the home button, scanning a fingerprint and unlocking the phone happens in 2 seconds with no lag. Maybe it's just the theme you were using, Idk. It's still really early on for this phone, I'd expect a release day update. But if this chrome lag and page refreshing keeps up I'll likely be returning this thing within the 14 day limit. My $400 MXPE performs better.

Ok, thanks guys. I'm on Tmobile as well - just did a factory reset and still have the same prob, so meh. Enough of an omen for me to get out while the getting's good.

When I had the S6 Edge Plus I noticed that there were a few themes that caused lag but then they were eventually updated by the creator and the lag went away.
Sent from my iPhone using Tapatalk

I tried 4-5 different themes and i "feel" lagging with only white theme of tech section in Samsung themes.

QQ. Are you all rebooting right after you install new themes? I noticed on the S6 that this step was critical even if not directly recommended.

Did you use the AoD enabled themes? (always on display) - it only seems to be the ones with animated lockscreens that cause the lag, the Dino theme in that category does not, for example

I have rebooted several times, yeah. Also tried clearing cache and even a factory reset, with the same problem (just rushed into the samsung store and got a theme after the reset)
Are there any updates out already or anything I might be missing? Dont get why I'd have this prob and not someone with the same device/carrier like the guy posting here before, unless I just got a skunky phone or something Think I'm going to head to the T-Mobile store tomorrow and make them try it on one of the test units..

My lag came from when a theme applied a live wallpaper to the lock screen. I changed that back to a static paper and all is good again

@nukularpowar yes i have aod in every theme i tried. With England and others 2-3 everything was ok and very smouth but with white theme i found a little laggy from aod screen to unlock screen, also the scrolling seems to be slower than the others themes.

I've tried an AOD theme, I got no lag here using the Exynos variant

Thinking of buying this phone but...

I have checked this phone in two different stores in retail mode. Both phones presented a weird slowness when coming back from an app to the home screen. Not always but sometimes. It took 2-3 seconds to load the home screen and icons. It was very weird from an otherwise snappy phone. Have any of you experienced this?

I have never experienced it. Own it for 5 months now. Lightning fast.

I second this. Hardware is top notch including the display. All the bells and whistles included.
Can you buy from somewhere you can return if not happy.
Slow has never been associated with the Mate 9. Software design is their main issue nowadays. They change/remove things without any real reason. Getting better with every version.

Lag, Stutter, freezing. Definitely NOT an issue with this phone. Best phone out. Buy it.

I would go for the one plus 3t software updates are gonna be a pain on this mate 9 already regret the purchase. Software always over hardware.

possible demo mode?
i agree software is going to be a pain, but this phone is amazing out of the box.
a little tweaking and youd never have to worry about updates...just the dev of this phone is going to be really slow until huawei release binaries...

Yeah but who likes sticking to an old version of android? Sorry new updates = security patches and overall a better experience with new features. I could not see myself recommending this phone to anyone on xda, maybe other people who do not care about updates and development.

I've came from Nexus 6p, OP3T knowing there wouldn't be much development as those phones had. But I would say this phones​ software isn't that bad, or as heavy as Samesung or LG. Ive rooted and returned back to stock which I am using now on the US version. It's an amazing phone as is and the camera blows out the OP3T and screen size is a must. I hate little phones​ (personal preference I know) so yeah the Nexus and OP do have the development communities but for the price and how well the phone is made and the smoothness of which the processor handles the work load it is definitely a great phone.

It was probably running an early build. My Mate 9 has had 3 updates since I got it. No lag whatsoever.

Same here, no lag in any situation. Buttery smooth. Though I got rid of the stock launcher as soon as possible.

I get it sometimes. Coming out of an app and the screen will be blank for a couple of seconds (just the wallpaper) then the apps appear

Lag is normal on my 156 fw. No double tap to wake up. And other things. But one is fine battery.

No issues here. Smoothest phone I have ever had.

S8 is much slower than the Google Pixel?

Hi all,
Just switched to the s8 from a google pixel.
Beautiful phone, but if is noticeably slower, in many ways:
1. Poor screen responsiveness of the keyboard. Typing on SwiftKey is slower on the s8 than the pixel. It seems that take a split second longer to recognise the touch.
2. Scrolling stuttering. The pixel's scrolling is buttery smooth. The s8 seems to be seriously slopping frames for something as simple as scrolling a page of text on chrome!
3. App switcher. It's really very jelly compared to the buttery smooth Pixel.
Anyone else experienced these issues, and /or have any thoughts?

I had moments yesterday where my S8 had skipped or stuttered, but it's been perfect today.

No issues here, and I'm no samsung fan boy. I've got iPhone 7 plus, zte axon 7, lg v20, and I've owned nexus devices. But with My track record with samsung I'd know for sure in 2 weeks lol. Happy so far

Has been butter smooth for me and I have not noticed any lag on the keyboard or in any screen. Not sure why you are experiencing such poor performance.

Pixel is bare bones and Samsung is full of features and customization (some useful and others a waste). Samsung is know for bloatware which slows the phone down, but my S8 is fluid.

I noticed the same thing
I noticed a delay with my s8 compared to the pixel xl when I happened to switch between apps on both. To test it out I opened up the same two apps and double tapped the toggle window button. The s8 is slower and not as smooth. There may be an animation speed setting that makes it faster but still seems like it wouldn't be as smooth.
Typing this in noticing swift key going slower too.
My battery is at 15% so maybe something is optimizing it and slowing it down...

Started having problems again. Ironically, similar to the problems that caused me to switch from the S4 to the S8 and to what the OP mentions.. Freezing of apps and high battery draw. Stuttering and slow to switch apps and unlock. Problems with keyboard not recording keystrokes. Then it goes b as back to being perfect again.
There is an update ready, but I'm having flashbacks to the update that locked the S4 down. I know this phone is already locked down more than the S4 ever was, but still...

No problems here. It's really fast. Faster than my old S6 Edge.

Yep another week and a half we'll know, hoping it doesn't. But if it's going to I hope its before my return window. I think samsung finally made a good speedy phone.
To anyone wanting to help speed it up and block updates until there sure it's a good update. I disabled updates in developer settings, and set animations to .5x.

Unfortunately, I don't know how to get rid of it. (Yet) I'm pretty sure once you set it up to stop updates it doesn't show up. But same with my case I didn't know the update was going to break bixby button so I stopped it when I found out. Now mine shows, and I've tried to get rid of it by blocking its notifications thru holding down on it and going to its settings. But it still shows up. I'm still working on a work around to get rid of it. Once I do I'll let you know.

I can't remember if we can just download it and then once it offers to install maybe we could ignore it but I forgot if that was the case for 7.0 update for s7e

I'm getting stuttery scrolling across various apps. Some are smooth though, and others more like a mid-range phone from a few years ago - not what you'd expect from a flagship device today.

I'm experiencing the stuttering apps. As mentioned in this thread, disabling window animations has helped with this experience.
This is my first android phone since the HTC one X.
Can we expect any custome ROMs? Or updates to improve performance?

Not all apps are created equal, some are smoother than others simply because they're written differently.
