[Q] Random dead spot on screen? - Verizon Samsung Galaxy Note II

Hi all, sorry my first post is asking for help, but I'm lost on this one.
It doesn't happen all the time, but I randomly get a dead spot on the bottom right corner of my phone.
It happens when I touch the app drawer, and the L key when I'm texting. It only randomly acknowledges I touched the screen.
Restarting the phone usually helps, but does that mean it's software or hardware?
Should I have it replaced?
Stock VZW Note II, no apps installed.
Ty for any and all help.
-edit-
It was replaced for a bad digitizer.
When using Multitouch visibility test, if you put more then 4 fingers on the screen, it locked up the phone requiring removal of the battery.

Perhaps instead of software, could it be heat?
It sounds like a dead/dying pixel to me. If it is only there on certain screens, then probably not, but if its there on say the boot screen or something, then I'd take it back.

I'm sorry I should have been more specific.
It's not a screen blemish.
It's when I go to tough the screen.
Like if I hit the L key on the keyboard during a text message, it will only register a touch like 50% of the time.
Or if I touch the app drawer, I have to hit it multiple times to open it up.
The actual screen is perfect, no dead or stuck pixels at all.

I'd return to Verizon, especially if you're not rooted so it won't be any trouble returning to stock etc.
It's probably mildly annoying to you now and it's only going to get worse over time. If there's no physical damage to the phone I don't see them giving you any trouble.

No damage at all, and I actually went through 3 screen protectors before I figured out it wasn't them.
Kinda bummed I have to drive 45 miles to return this damn thing though.

You don't. Call VZ and they will ship you another and give you a prepaid box to ship the old one back in.

I actually called them, and they told me to just take it back to the store in case the replacement has issues.
Which is troubling to hear.

I have a youtube video demonstrating the problem, but I won't let me post it so ohwell.
Will have to wait til I get 10 posts.
Basically, using multitouch visibility test, I roll my finger around the bottom right corner while never lifting it off, and it won't recognise my trying to touch the specific spot.
After I life my finger and move it around the screen it will recognise the spot. It's very random.

Here's the video.

-edit-
The youtube tags aren't working?

So what do you all think?
Hardware or software?
After further messing around in Multitouch Visibility test, I can replicate this all over the screen, but it's easiest to do at the bottom right corner where L shows up on the keyboard.

That would only affect the S-Pen, from what I understand.

Nah, it was a bad digitizer they said.
Whenever you put multiple fingers on screen, it would lock up, and require yanking the battery to reboot.

When you notice this are you holding the S-pen? I noticed if you get the pen near the screen (close enough for air hover to work) that the screen and buttons quit working to touch. For a little while I thought the home button was having problems, turned out the way I was holding the pen would result in it being placed near the screen when I hit the button.

The main reason I noticed it was when I was texting.
Whenever I went to type words like sleep, or talk, they would be missing the letter L.
Or when I would go to open the app drawer, and it would only work half the time.
All while the pen was in the phone.

The lockup doesn't sound normal but as far as dead spots if you have a screen protector on have you tried removing it? Marginal screen protectors will cause touch input issues.

Dislike the swipe lock screen? There's an app for that.

I personally find it too cumbersome to have to press the unlock button AND then swipe again on the lock screen. There is a free app called "No Lock" in the market. After you install it, you just press the power/unlock button and your are in.
Obviously for those of you who need security and have passwords on their lock screens, this won't be of much help.
*Tip* If you don't have a gel case yet, get one. I bought the gel case from T-mobile and it covers over the lock key in a way that you have to press it in with a little bit more pressure (but not too much) which should help you avoid accidentally hitting the button while it is in your pocket.
Good tip about the gel case, but I don't think I've ever hit the lock/power button by accident. In fact, I actually have a bit of trouble hitting it sometimes.
Also, I personally can't stand gel cases. They slide around too much on the device, and stick to the insides of my pocket.
great tip! I was really starting to get annoyed at the awkward unlock then swype
Yeah, I just picked up my black case from T-Mo today. Gotta tell you it's great, and makes the phone look good as well. Oh, and it also adds some weight to the phone which feels really good too.
It seems like this app doesn't run at start up, does anyone know how to make this happen?

I agree. I was worried about the stickiness before I bought it, but thankfully that isn't an issue at all. It also adds a good amount of weight to the phone. Without the case it seemed to be too light. I think this is the first smartphone that has a problem of not weighing enough.

well, it has good intention, it just doesn't work for everyone.
The obvious idea is to prevent things on your homescreen from activating if the phone is turned on by the button (aka activating crap while in your pocket such as dialing people).
the reality is that a lot of us are completely annoyed with the unlock screen because it's just one more annoying step
I prefer the double tap to unlock... like pressing menu twice on the g1.... I like the swipe screen too tho bc it shows of my mario lwp...
I also agree on the being too light of a phone... I was looking for it for a few mins yesterday just to notice it was in my hand... and I dont feel it on my lap while sitting (bad for standing up or exiting a vehicle..)

I don't have mine yet, but i hope to not have that problem, i always put my phone on my lap while driving and had dropped it a couple of times when exiting my car, it sucks
agree with the phone being really light, that is not a bad thing maybe a bigger battery will come along, and the gel case that came out from t-mobile same time feels really nice emphasis on the really. As far as the lock screen, i like the puzzle lock feature BUT the default one when no events sucks... any way to only change that part?

Yeah, I wouldn't mind a battery that made it g1 size as I am used to that, I am not going to say being light and thin is a bad thing, but being used to my G1 I don't think I would whine about more heft, and if we could get a 3A+ battery that would be rockin
The constant swiping was bugging me too. It almost made me miss my G1. Thanks for this suggestion. I'm going to download No Lock now.
I don't know why the manufacturers added screen wipe to unlock the screen and I think this is a hassle.
It's good to know there's an app to disable it and I have it installed on my nexus one.
i mentioned this in another thread i think in development:
No Lock does not stick on reboot, but is a great alternative to the double-lock issue for me personally.

Actually it does stick on reboot. After I installed and it tried it again for the first time after rebooting, the lock screen came up. This is normal. Let the phone fully boot up, and then it will load No lock. You will still have to slide the unlock screen, but only once at the time of boot
I've been using it for about 2 days, and every time I restart, it takes a little while but I only have to unlock the screen once
I like the app since I think the lock screen is retarded. The only thing I don't like about it is that the phone unlocks in my pocket when I receive a new text message (as you can imagine, this happens a lot) and it's really annoying.
Does anybody know of an app that lets you customize what unlocks the screen? I don't really like being able to unlock the phone with the volume rocker, either.

gravis, do you have a case for your Vibrant?
I've had my phone in my pocket all day with No Lock on and I don't think there were any accidental button presses. The case that T-mobile sells works great cause it makes it pretty difficult to hit any of the side buttons by accident, you have to put a good amount of pressure in specific areas.
So if you don't have, please consider getting one, they also protect your phone and I think it makes them look cooler.

I don't have a case, but that's not what I'm talking about. An incoming SMS wakes up the screen, whether it's in my pocket or even sitting on a table. Before it would just go to that puzzle screen but now (with No Lock) it goes straight to the desktop and if it's in my pocket things get crazy.
Basically what I'm asking for is if No Lock could get rid of the "Swipe to Unlock" screen but not the "Puzzle Unlock" screen for SMS and missed calls that would be great.

[Q] Sensitive Home, Search key..constant launching in landscape mode

When i'm in landscape mode taking photos, playing games.. i find that my palm is accidentally either launching the recent apps screen overlay (from pressing home key a few seconds) or launching the search key. I don't feel like im over doing it. I rest my palm on the bottom right corner. When i now pay attention, I try to hold the Evo 3D in landscape mode with my hands in two C formations facing one another.. so that i dont accidentally launch those quick keys.
Are any of you having this issue too? it's annoying to frame a photo.. and then the Recent Apps screen keeps coming up and I have to back up out of it. Would a case be helpful? possibly looking at one of the TPU cases when they get it back in stock. is there a way to adjust the sensitivity of the keys?
i've done all the OTA's available..
It's normal. Happened on my EVO 4G all the frakking time. You just need to be careful not to touch the capacitive button. You don't actually need to touch the button to activate capacitive button/screens, only be a few microns away.
I also have that problem I'm hoping root will fix it

ok thanks that is unfortunate.. that is exactly what is happening.. just barely a tap on the lower edge triggers it. Wish they could've moved the sensor away form the edge.
My otter box defender stopped that from happening to me. I know this may not be a solution you may like but I'm just throwing it out there. I need the case due to me working on cars as a hobby and I will lay down on my phone while under a car not even thinking about it.

Just wanted to update.. having a TPU case with the raised ridge on the bottom defintely is helping prevent the unwanted "ghost" launches from the Recent Items and Quick Search capacitive buttons.

Screen Loose After Prolonged Use?

So my Prime's screen gets "loose" (clicking sound when I squeeze the front and back of the Prime) around the volume rocker area after I use it for a while. It seems that it spreads farther and farther as I use it longer and longer and after I leave it for a while it goes away.
Also, when I press hard on the screen at aprx 2 inches from to top left pointing towards the center, the screen turns black (not off, but black).
So what should I do? It is not bothersome enough (yet) to send back to Asus for repairs but should I call them to let them know and record the problem on my Prime's serial or something? And do you guys know how long the whole process would take if I send it back to them for repairs (Im in Canada).
Thanks
Mine does that too. I think it's a common characteristic and read about others who have also remarked about it. The TF101 had something similar as well.

Does it also only get loose after prolonged us? Is it because of the tablet getting warm?

Beats me, I've had mine for 3 weeks and it's been about the same all along.
I haven't noticed any clicking on mine, but my screen sticks out from the casing a little bit (evenly - all sides). Does yours stick out, too? I figured it was just a poor design choice by Asus. And if yours does, that could be the reason for the clicking since there's probably some wiggle room.
same issue here near volume button... i hear clicking sounds... made me bit worried...

Please, help correct me if I'm wrong...

My Galaxy Nexus died in a horrible freak accident, and SquareTrade ended up sending me a wad of cash to find another phone. Logically, I wanted to take the S3 for a test drive because it's the newest, hottest kid on the block (and I missed not having a MicroSD card).
I picked up my T-Mobile S3 in store today for the full retail price, and walked out excited as I always am to have a new toy in hand. Now, beware, I'm going to say some negative things about this phone, but that is because I want you guys to tell re-assure me that I'll learn to love it, or they'll get fixed etc because I really want to like this phone.
First off, the good things over my dead GNex:
Speed: Holy cow, that Krait CPU is blindingly fast. I knew the GNex was never a rocketship, but I wasn't aware of how slow it was until I played with the S3. Things run like butter, and JB(4.1) is only going to make that more amazing.
Camera: Yeah, the GNex camera sucks. This isn't as amazing as I hoped it would be, but it is nice to have something that instantly looks like crap.
Screen: It is a sweet screen, but I'm not sure if it is better than the GNex. If it is, I don't really see it (and can't compare side by side) and is still in amazing screen.
Now, the things I don't like:
SMS: WHY THE **** does my SCREEN turn on EVERY TIME an SMS comes in??? WHERE IS THE SETTING TO KILL THAT?!
Lockscreen: The "barely touch" to unlock is a joke. (Yes, I know you can replace it)
The body: Man, that blue looks pretty, but holy balls is that phone a pain to hold on to in 90 degree heat. What's the point of making a gorgeous phone that you have to keep in a case?
Build quality: It honestly doesn't feel as "solid" as the gnex, but has anyone had any quality issues with theirs yet?
Bloatware: I thought the Sensation was bad when I bought it, but this phone has so many apps that I never want to use, it's not even funny. I spent the first half hour going through and disabling applications.
Signal Quality: I drive a certain stretch of road that is hell on connections. I've had HTC's, Samsungs, etc drop out. It's just a great place to test radios and phones... Well, this one? Drops as much as the old HTC G2 did, if not more. Absolutely impossible to keep a signal. Now, thinking it was a bad signal day, I popped my micro SIM in an adapter and back into my HD2 and drove the road again... This time? No issue.
Home button: Really? A hard to press, narrow button for the most used button on the phone? I worry about dropping the phone, as it is so light, I have to hold it tightly with one hand to press the button.
So I know this may seem petty, but I'm really hoping you guys can convince me one way or another. Sure, this phone will always be faster than my GNex, but a GNex is half the price, and for me, in many ways feels like a better phone.
Thanks
Another thing I've notice, the screen can't figure out if it wants to be dim or bright. It'll sit there and go from one extreme to the other over a minutes time. Never in the middle.
Is it sounding like I have a defective unit?
I also had a Nexus Prime and I would of kept it if it had an sd card slot and WAY better camera & that's where the S3 comes in. Sure it has bloat and touchwiz isn't the best but AOSP is on its way & with it, improvements. As for build quality, I like it better than the nexus. Signal wise I was have at least 3 bars so I'm happy. I do agree though that the unit gets quite hot sometimes, but overall I love this device
Higher the processor speed the hotter it runs. You could limit the processor speed but you lose the blazing speed.. but I also lose the blazing heat. LOL.
As for the build quality its not bad. It doesn't feel like it'll break when I try to bend the unit. The gorilla glass is pretty strong but its not shatter proof. Don't drop it! Already seen a few shattered screens.
The software issues are just that.. all just software which is easy to change either by using replacement programs like handcent SMS or rooting then replacing the rom or disabling and removing the bloat. All that should matter is the hardware and if you're happy with the performance, look, feel, battery life, and reception.

Yes handcent fixes that screen on issue if you disable popup notifications. That's the kind of notification that shows a dialog box with a quick reply option.
If disabled then the screen doesn't turn on and the SMS stays in the notification area.
Infact you can enable the pop-up notification but choose to disable screen on for pop-ups. That works too.

Are you sure you don't have the eye/face detection turned on? My screen does that at work (I have mine set on) and even though I'm not directly stairing at it, it picks up my eyes (I have my phone placed below my monitor). Sometimes it bugs me enough just to turn the thing face down.
or maybe it can be the autolight sensor.
:shrug
There's a setting in gosms to turn off the "screen turning on with an sms" option
My major concern is with the home button. What on earth were they thinking?
I'm a firm believer that AOSP on this phone will make it a true winner with the on-screen navigation buttons enabled and the capacitive and physical ones disabled. Maybe we could repurpose the big ol physical one to do something else in the future.

Yeah, I turned off a lot of the gesture/motion things right out of the box, as some just didn't seem natural at all. I could never get the whole unlocking motion one to work either. That was annoying for a bit.

The sad thing is, as much as I'd love to have on screen buttons like the Gnex, then we're stuck with that long chin being nonfunctional. I guess it wouldn't be bad if the back and menu button never lit up and were completely disabled. Possible use the home button as a shutter button then? Who knows.
It really does blow my mind how they did a physical button for the home button of all things.
I enjoyed a physical home button on my previous phones. To each his/her own?

I loved the ones on the HD2. However, they weren't as difficult to press, and the phone was a lot heavier. It made it so when you pushed them, the phone didn't want to flip out of your hand. The SGS3 is so smooth and lightweight, I don't even try to hit the home button one handed anymore.

Although I have a trackpad on the g2 I use it to turn the phone on so I love the home button on the s3 since a lot of times I leave the phone on the desk or table during lectures and stuff and its just convenient to turn the phone on that way but like some said its hard to press without fearing of it falling out of ur hand due to the large size and thinness

Maybe you have smaller thumbs? For me, I have a big wide thumb, and I have to press with enough force to make my thumb "go into the recessed" area to completely depress the button.

Ghost touches

So I'm watching youtube on the dual screen using landscape and I want to sleep the main screen so i touch sleep main screen option on the dual screen tab tool, it shows a prompt saying main screen will dim to save battery and swipe to dismiss. I dont touch or swipe anything and the prompt swipes itself away and screen undims or sometimes doesn't even dim. This is also the case with Call of duty mobile, when I'm playing the game in battle royal mode the mini map enlarges randomly even if I don't touch it, and the voice chat options will engage and open without me touching those as well. Anyone else has this problem? Any solutions?
I could have sworn I saw a post earlier about ghost touches, though I can't seem to find the thread it was in at the moment.
I've been using the phone heavily since I got it on April 1st, and I have not experienced this issue at all.
Any chance you had an LG phone prior to this and used LG Switch to transfer over all of your stuff?
I've read reports here that doing so can cause some pretty serious battery drain and/or lag issues, so there could be other bugs as another side-effect.
Have you tried a factory reset?

I could have sworn I saw a post earlier about ghost touches, though I can't seem to find the thread it was in at the moment.
I've been using the phone heavily since I got it on April 1st, and I have not experienced this issue at all.

Yeah I think I read that thread. I haven't tried a reset since I already used so much data to download apps and don't want to setup the phone again. I did use the google cloud restore for my contacts and I also had the t mobile April security update. Mejilan can you tell me if you can put your main screen to sleep while watching a youtube video on the dual screen? Please tell me what kind of result you get. Thanks

I set aside the the dual-screen accessory because it's just too uncomfortable to hold for most use-cases.
I'll go dig it up, plug it in, and give it a shot later, when I have some free time, and report back.

If you play a YT video on the second screen and lock/sleep your phone, the second screen goes to sleep as well.
I didn't bother with headphones for this test, and noticed that the audio comes out of the phone's speakers.
It appears that the second screen doesn't have speakers of its own.
So yeah, you cannot watch something on the second screen while having the phone asleep.
And it make sense. It's just a screen. No second pair of speakers. No second headphone jack. No separate battery. No second set of modems, etc.

It actually was working for me last night as far as the putting main screen to sleep function but call of duty still acts up I'm hoping the update for the game on May 1St will fix, but sure whenever you get a chance...

I answered your YT question one post above yours that I just quoted.

Actually you CAN watch youtube on the second screen and sleep/dim the main screen by using the floating dual screen button. It has an option asking if you want to sleep dim the main screen to conserve battery life. It does work for me now, I'm not sure why it was going wonky on me when I first posted but hopefully that it doesn't do it anymore. I'm guessing the tmobile April security update did the trick. It's just I have phantom touches on call of duty still.
Lowe941 said:
This is also the case with Call of duty mobile, when I'm playing the game in battle royal mode the mini map enlarges randomly even if I don't touch it, and the voice chat options will engage and open without me touching those as well. Anyone else has this problem? Any solutions?

This is happening to me as well when I'm playing PubG Mobile. The ghost touches are happening not on the map but to the left of that. On another LG V60, the device would get random dead zones as well.
I'm going to do the following test and suggest you do the same and report back your results.
1. wait until the ghost touches start happening and flip the phone around. hopefully the ghost touch continues to happen in the same exact location of the physical screen, and it triggers a different button
2. remove the screen protector and try the tests again
are you using a screen protector?
might process a warranty replacement if the results are reproduceable

Oh, that is good to know. I'm not using the dual-screen attachment anymore (typing in portrait mode is IMPOSSIBLE with it), but I only ever used the Dual-Screen notification shade tile to enable the second screen, not the pill button thing. I should have explored our options more thoroughly. Thank you for correcting me.
Edit - I have recently added a tempered glass screen protector to my phone, and while it completely screwed with my fingerprint biometrics (I had to delete the fingerprints and redo them), the protector itself is not causing any ghost touches for me. And once I redid the fingerprints, there have been no further issues there either.

Yes I am using a screen protector and I was actually thinking that might be the problem, although it seems like a solid install. I just got the update for cod season 6 and I'm downloading now. I'll see if that solves the problem. I'll also try what you suggested and then post results
Update: so the cod update did not fix the issue, but I tried doing as you suggested and flipped the phone around and the problem went away. I then tried flipping it back to original and problem persisted. I think it is the tempered glass. I don't want to remove it since it cost me 40 bucks. Any suggestions?

So I installed the update for cod and it still had the ghost touch problem with the top right side of the screen, iflipped the phone per what jd254 suggested and I didn't get the phantom touches. I'm assuming it is the tempered glass that is causing it. I dont want to remove it cause it cost me 40 bucks.
2nd update: so I tried taking it out of the dual screen case and notice it doesn't have phantom touch ( I played a full game of battle royale) so I'm not sure if its the tempered glass or the case. Need to investigate more

Is the case touching the tempered glass anywhere around the the edges? If the case is pressing on the screen protector and lifting or peessing it even the smallest amount that could cause phantom touches maybe..just an idea
FWIW, I'm using both a tempered glass screen protector and a case that wraps around to grip the front of the phone a bit, and I'm not getting any phantom touches at all.
The case is NOT rubbing up against the edges of the screen protector, however. Which is fine, because if it were, it could potentially dislodge it.
Or, I suppose, cause phantom touches.

Ok more investigating and playing codm I notice that the mini map opens up when i perform a touch combination with my thumbs. So the map gets triggered when I press and hold up on the left side virtual joystick to sprint and press the jump virtual button on the right simultaneously. I can't recreate what button presses open the voice chat box, but now I have to strike the dual case as being the problem along with the tempered glass, at least i assume those aren't causing the ghost touches.
For anyone having touch issues, as a troubleshooting aid: enable developer options, and then toggle on "Show touches" and "Show touch data". Might help figure out what is going on.

I'm getting VERY interesting results.
1. dead spots: I moved my finger up the right side of the screen to look up. my character did not look up, which I would assume there was a dead spot before. This is incorrect. I can see the screen registered using that option mentioned above. the screen registered the action, but didn't pass it to the software?
2. FPS drops: I assume it's an FPS drop because everything was laggy when this happened. (PubG mobile was set to max settings, and runs 100% fine, until now) I was flying the helicopter, so I had several fingers on the screen at the same time, with a lot of rotational movements. the screen doesn't clear all of these movement data until I literally take all my fingers off the screen for half a sec. When I did that, it stop lagging.
3. ghost touches: Each touch on the screen has an x and y axis point to tell the software where it's being touched. With several finger on the screen (sometimes 2, but commonly with three or more), I noticed that the y axis for my left thumb and the x axis for my right thumb was creating those ghost touches! The screen would combine the x and y axis from different fingers to create a touchpoint on the screen.
so I don't care too much about 1 and 2, but... what can I do about 3?

Yeah I noticed a combination of touches triggers the ghost touch on call of duty, I could also be having the combinations trigger ghost touches in other game but I need to test more
