[Q] Section of Screen Unresponsive

Hello,
I just noticed a couple of days ago that a section of my screen has become slighly unresponsive. It appears to be intermittent, and Swype in Landscape mode is primarily affected.
In landscape mode, keys m, j, and u are not responding. During shutdown as well, the power off confirmation both yes and no button locations are unresponsive.
These areas of the screen are responsive usually, except during power off confirmation and using Swype. Could this be a software issue?
Does anyone know what might be the cause, or how to fix it?
I have not yet tried any fixes, though I may just restore using a backup ROM I made shortly after I rooted my device. If that doesn't work... then :|
EDIT: This appears to have started shortly after I installed LauncherPro, or it may have also occurred since I removed all pre-loaded Google Apps to replace with the newest versions off the Market. :\
EDIT 2: Restored my ROM, m key has regained some responsiveness, other keys no good. Using Swype, the line goes near them, and then just breaks, sometimes. Other times, if I swype really fast, I can passover and include the key, but cannot swype up vertically among them. Unable to press them directly either.
Switch to Android keyboard and things seem to be ok again... fully responsive... this is weird.
EDIT 3: Crap... one row in the middle seems to be affected... somewhat. Downloaded a drawing app, and this one row doesn't want to play nice. It responds properly in most instances, yet there definitely seems to be a problem.
EDIT 4: Appears that a section of my screen is non-responsive. A whole row. Argh. When I move shortcuts, passing nearby this 'dead row' the icons jump. In swype, it acts like an invisible barrier, either I move really fast and it sorta jumps across that key, or I move really slow, and it's like my finger is lifted off the screen. Android appears to be compensating heavily for the non-responsive section and guessing my inputs. Tapping in this area still appears to be somewhat responsive, dragging or swiping across this area is producing very mix to bad results.
I need to have the touchscreen/digitizer replaced, right? The LCD panel appears to have no issue. Argh. Could it be due to the InvisibleShield I put on top?

I had a similar problem with my G2. I tried putting one of the Zagg protective covers on it and immediately afterwards the touchscreen would not respond properly. I would have dead spots on top right of screen and bottom left. At first I thought it might have been from the solution seeping into the phone, but I think I might have used too much pressure and damaged the digitizer. I ordered one earlier this week and will update you with my results.

The screen is capacitive... which means that your finger completes an ELECTRICAL CIRCUIT. If your screen protector is blocking current at all, this will manifest as a loss of sensitivity.
The second thing to understand is that you can't just touch the screen with your finger to complete the circuit, the other end of the circuit has to be completed as well. The metal ring around the screen is the other side of the circuit! You need to be touching that metal ring in order for it to work properly. Even with the phone just resting on your hand, you may not be contacting the ring and may experience a loss of sensitivity. In portrait mode, try clamping your fingers around the back of the phone to contact the ring on the far side. In landscape mode, use your index fingers to touch the top part of the ring.
If these suggestions don't help (including removing the screen protector), then you most likely have a bad digitizer. Check the ribbon wires to make sure that they haven't pulled out at all before replacing.

Just replaced my digitizer and it works great now.

[Q] Screen too sensitive

My Acer A100 (love it to pieces) but my screen is a little too sensitive. On my A500, under Settings/Screen there is a option to change but I haven't found anything on my A100.
Any suggestion?

What do you mean it is too sensitive? I didn't know that was possible.

I find it too sensitive too. Always double typing letters with thumb keyboard and unintentionally clicking when trying to scroll. I didn't realize there was an option to adjust on my A500, but i haven't found a need for it on that tab. I've looked for apps that might help, but no luck.

I agree that the unintentional entry into threads while scrolling seems to be a reault of over sensitivity. Starts to become rather annoying after a while.

Glad to see I am not the only one. I suppose that does not offer a solution on how to make it tolerable.

One thousannd dtimes this. I could type on my trannsformmer with thumb keyboard like a champ. With tthis thing, I have to type soo painstakingly to avoid ddouble keypresses.
The above was not exaggerated for dramatic effect.

You can put a screen protector on it. That will reduce the sensitivity.

THAT. Is a good idea.

I have put a screen protector; also as suggested by Acer tech support, removed the sticker from the side. Still too sensitive for my liking.

I also find too sensitive and have a screen protector installed. I also find it hard to click on links. If there are two links close by I always click on the one that I did not intend to. Seems its a little off. Anyone have this problem?

I have had my a100 for 2 months now. I really like it but what I find irritating is the inconsistent screen response. Most of the time it is too sensitive that it toes a letter multiple times or the back button will go back more than one screen. Other times I have to hit a link or a button a couple of times before it responds. Sometimes I hit a link and a link adjacent to it will be launched. I also have problems with scrolling a it will launch a link instead of scrolling. I already have a screen protector but it did not improve things.

I was just about to start a new thread for this, but it seems like a common problem with the A100.
Scrolling through my dropbox is nearly IMPOSSIBLE, every time I try to scroll, it clicks a link.
Also, trying to long press a item can be difficult, because it will treat it like a click instead of a long press.

I was having the same problem too!
I found out that after disabling SwiftKey X tablet keyboard returned the Acer to a great state of sensitivity level.
This might be the same thing, but with another keyboard or something.
I was constantly pressing the wrong icons and doing unintentional actions while scrolling!!!
I hope this could help.

how did you disable it the swift keyboard?

jahciple,
You either uninstall it from My App in Market App. Or uncheck the keyboard from input methods.
I hope that works for you!
Please post your feedback and share it with us!

nm i thought you were referring to the stock keyboard.

I think the problem when scrolling and it accidentally selecting is because the touch screen loses connection with your finger and thinks you lifted it off and then touched it again. If you download multitouch vis and test touch sensitivity by running your finger from side to side that the colored dots will flicker or sometimes disappear as if you lifted yout finger off. So I think its not because its too sensitive but less sensitive. This happens more if you just lay the tablet down on a surface so only your finger is touching it. If you touch the bezel with your other hand it as you touch test with the other then it will respond better. This could possibly be grounding issue.

Definitely having this problem on mine. This is really the only issue I have with the device, and it's quite frustrating!

Same here. Sometimes when I'm scrolling on the home screen it either scrolls backwards or scroll two pages over (skipping one page). Anyone else have the issue? As for the other issues (clicking links while scrolling) I experience those too. I really love the device too. I was gonna get the Nook Tablet but I gott this for cheaper and it's just as good if not better.

i think we need to bring this up to acers attention. Im sure its just a matter of software update. When the original evo 4g came out it had touch screen issue where it wouldnt respond correctly unless your touching the device with your other hand. It was fixed via software update. Same thing happens with this device. Again download multitouch vis and you can test touch sesitivity while laying it on a surface while running one finger all across the screen you will see it flicker as if its not recognizing complete touch. But once you hold the device up with the other hand while touching the screen with the other then it doesnt flicker.

apps shrink into bottom quarter screen

gn vzw 4.0.2 stock.
Three apps , overdrive, united airlines, and continental airlines , all start up in the bottom left quarter of the screen, and are unusable.
The screen is completely back, except for a rectangle of the bottom left quarter, and the app itself is in the top left corner of that rectangle.
Anybody else seeing this? Any ideas how to fix it?

In settings if you go to Developer options, is Force GPU rendering enabled? If it is, try disabling that and see if it sorts out the issue.

[Q] Air view & Spen problem.

Guys pls help enabling the air view feature is creating some problems .
Wen I use spen to type on keyboard with airview On. Then wo touching the screen the spen types watever letters it waves over.
Spen also selects application automatically wo touching it just by waiving it over the screen.
As soon as I switch off airview the problem ends.
Pls help is anyone facing the same problem.
Or any solutions....??????????

That is not a problem related to airview.
It was a known "bug" on original Note spen and it has definitely been carried over here too.
That s pen sometimes clicks even when it is 4 - 5 mm above the surface.
It is usually when the mobile is....on flat surface afaik...
Its not related to airview

sounds really stupid but reading another thread on here someone said to slam the pen down on its side as to not harm it and it will work perfectly......mine was doing the same thing as yours an it was very frustrating....this fixed it immediately and now it is awesome!!!

I tried tapping the pen, moving the tip, cleaning, turning air view off - nothing fixed it until I adjusted the potentiometers

Love the Note 4 EXCEPT a few that bother me

I love this phablet. Came from lg g3 and I have to say I love the Note 4 little more.
But there are a few things that I don't like. I hate actually.
1. The bottom of the phone, non-screen area. Space is small vertically and I constantly launch an app on the dock when trying to press the home button. Especially when using the phone one handed. Samsung could have moved the screen up put the logo on the bottom to make the space larger. This is a QA usability fail.
2. Fingerprint sensor limit to 3. While I was able to program 6 fingers, it doesn't always work well and needs multiple swipes. I also would like to see apple like sensor that doest need swiping.
3. IR remote software is terrible. Just give me a programmable remote like LG G3.
4. Front camera distortion. With wide screen format the distortion is so bad at top and bottom I can't believe it made it pass the QA..

While I can't really say much about points 1, 2, and 4 I can say there's this really nice remote app in the play store "Smart IR Remote - AnyMote" by Color Tiger that works really well though I think it's a paid app.

Point 1: I have never launched anything while pressing the home button. I even have a case on which reduces my flat usable space to push it. This is not a "QA fail", it's your personal preferance.
Point 2: I use my thumb which I scanned in twice holding the phone 2 different ways to compensate for different usage scenarios and I get it the first time 95% of the time.
Point 3: I agree that the IR software could be better, but I think it is better than HTC's. The software on my One M8 wouldn't work with my DVD player. With the Note 4 the setup was faster and it works with my TV and DVD player.
Point 4: I honestly haven't used the front camera, so I can't say much on it. I will check it out since you mentioned it though.

I agree on all points except #4 because I NEVER use it, but number 1 happens to me often. Maybe I just have big thumbs, but I am constantly launching something or hitting something when I press the home button. Best phone available IMO, but everything can't be perfect for me.

Number 1 used to happen to me all the time. I Just moved the icon from above the home button. Problem solved!

Press with the edge of your thumb and I bet it won't be a problem anymore. That's how I do it.

Try pie controls and set one of the first row as your home button... I never even press the home button anymore. Saves a little wear and tear over time as well.

some launchers allow for adding vertical padding, i don't know if it applies to the dock area but it's worth a shot if you're not set on using samsung's launcher. personally i have more issues hitting icons or long pressing by accidentally touching the sides of the screen when gripping the phone vs hitting something while trying to press home. but that could just be because we hold the phone in different ways maybe.
i have pretty good luck with the fingerprint sensor so long as my fingers aren't grimy or sweaty. but i found it to be generally a worse setup than the iphone (which works surprisingly well and fast) i turned it off after about a week. if it wasn't a swiping gesture i probably would have left it on as i found it awkward to swipe my thumb while trying to hold the phone.
3 and 4 i don't really use so i can't comment. i tried out the IR and it worked fine with my projector. i'll take a look at the FFC and see if i get any distortion.

I cna very agree with 2), I love apple's implementation of the finger print scanner. I hope we see future phones utilize the same way rather than require swipes.
3. is very solvable by using a programmable remote on the app store (smart remote IR+) which is VERY nice.
The rest I do not really have any experience or trouble with but we all use our phones differently.

I bought a remote app. But I feel like I shouldn't have to buy another app with a phone like note 4.
I'll try the home software button on dock.
