Touch screen sensitivity..do i have possibly have a problem?

it started out a few days ago. I started to feel like my touchscreen is not as responsive as usual.
I noticed numerous times it felt like my swipes as well as my touch (say when i want to open a specific app) are not being registered properly. Now the way i recall my samsung galaxy s, it would register a click sometimes even when you're hovering about 0.5mm to 1mm above it. So with that in mind, i thought i would try to do that with my one x. I would hover my hand slightly above it, and no response - NOTE: THIS IS NOT THE PROBLEM JUST YET.
Anyways, seeing as hovering over it doesn't work (which is not a problem imo) i would proceed to touching the screen, however i touch it without applying any pressure, i could even swipe and it WOULD NOT switch over to the next screen. I could touch the screen and the application would NOT register my fingers. However, after applying more pressure it suddenly gets registered. Even though the pressure i have to apply is just slight, Isn't this how a resistive touchscreen is supposed to behave and not a captivate touchscreen?
I thought that's because of my screen protector, i took it off and gave it 2~3 days and the issue remained.
Now my question(maybe even a favor) to you guys is as follows.
1. Try to click on an app, however, do this without applying any pressure, simply touching your touchscreen (might have to do this slowly). Does it respond? Or is it the same with with you as it is with me?
2. Please report in on the behavior of your touchscreen.
NOTE: I just want to know if my touchscreen is behaving normally or not. I do recall a better experience, actually if anything i was very happy with my one x's screen and this is simply annoying. Espeically when i have it on a soft surface and i push my screen, normally a soft surface tends to bulge in upon pressure.
It could take three touches for that freaking thing to register it if my phone is lying on a pullover or whatever else that's soft. Lately i'm not really happy with how webpages scroll up or down either, feels as if my swipes are lightly registered thus a sluggish movement upward or downward.. I hope this is not yet another issue that i have to deal with because my unit already had a wifi defect and, despite being happy with this device it might be my last. It's just too troublesome. Unless my stupid provider replaces it but i could keep dreaming.

0,5 - 1mm ? do you even realize how big this distance is? No way the SGS would register that... or react on that. (I come from that phone too)
with that in mind, my One X is much more responsive as the SGS or any other phone I had.
And no, I do not need to press. As the slightest pressure gives my screen ripples. not possible.
Either try another kernel if you have some custom one, I know there was some problems with those sometimes. Or factory reset if you are stock and then return it?

Well maybe i exaggerated the hovering part but within a certain (very small distance, probably 0,2 maybe even 0,1 the screen would react).
I've been from viper, to jelly bean roms, to ARHD and Maximus. Same thing.
edit: actually, 0,5 mm is hardly anything if you look at how big a mm is and put and reduce the distance by 50%, anyway that's not the discussion http://www.meb.uni-bonn.de/Cancernet/Media/CDR0000578121.jpg

Hover taps/clicks happen, I'm sure I haven't touched the screen a couple of times but it responded to what I wanted to do. Anyways, try this app called touchscreen test to confirm your issue.

So you are implying that hovering touch seems to work on your Hox?

Hovering also works with my HOX. And I don't have to use any pressure, hardly even touch the screen.

Tell them the digitizer is faulty and needs to be changed.

Help, screen issues

So ive had my g2 about two years now, its got is scratches and what not, but for the most part it functions well.
The largest issue is that sometimes when using the touch screen when i pull my finger away that area will stay activated like my finger is there. Happens a lot when using the on screen keyboard, and it seems to be getting a little worse.
Sometimes a good cleaning helps, but before long it comes back.
Anyone have the same experience, or able to recommend a fix.
Was thinking of doing a digitizer/screen replacement but figured id see if there were any experienced suggestions.
Thanks in advance!

since my phone is new I have this ''issue''.
I got it on the motorola milestone also.
But for me, the problem appear when I have sweaty hand ( stress or too much cofee). It looks like if I still press a key even if my finger is off.
My brother had the same problem on is galaxy SII , he put a plastic film (protective glass) and the problem is gone.
In inverse, if my fingers are too dry, the screen has difficulty to respond.
My solutions : wash my hans often, dont drink coffee, dont stress and wipe the screen on my jeans.

Thread moved to Q & A section, post in the relevant section next time.

Screen not responding well after putting on a protector

I put on a Skinomi screen protector last night and have noticed the screen isn't as responsive as before. Haven't experienced this with other phones before, wondering if anyone else has noticed this?

I specifically didn't buy a Skinomi for this phone like I had for my previous phones because I read that people were having trouble not getting the liquid into the speakers. If you think about it, it makes sense, and I'm not going to take the chance I would have the same problem. I haven't read about that specific brand causing problems with the touchscreen, but I know cheap ones definitely can affect sensitivity.
Did any liquid get in the speakers during the application process? Does your phone have the slight gap in the side like several phones do? It's possible the liquid could have gotten in there and could be affecting the touchscreen.
Thus far I'm not having any issues with the touchscreen with my dry application iSmooth screen protector. *knock on wood*

I figured out my problem was an app I had loaded.
No problem with water as I waited 5 minutes before applying the application....
Thanks for your response as I learned from it.

Touchscreen issues

I wonder whether this issue exists only between me and my note7..
Very often I'd have to press same thing (be it button, link, key) an extra time for the phone to actually act on it. At first thought it had to do with the way I was holding the curved screen but it does the same when it's sitting on the table for instance. Kinda reminds me of the nexus 7 similar issues a few years back.
I have tested the touchscreen already and all seems to be fine, in a test environment that is all touches register ok.
So what do you think about this, could it be just some fancy lag?

I'm having a similar experience with mine. It's not particularly annoying, but it's noticeable on a regular basis. I feel like Nova is also behaving a little differently (slightly off with accuracy when I drop icons) which I thought might be related.

I have seen the same issue. Every once in a while I have to re-select a link or touch an option one more time to get it to register. Hopefully this is just first release bugs that eventually get worked out. Not a big deal, but a tad annoying.

same experience here... encountering keyboard lag as well....

Yep ... I can confirm getting this on mine. I thought it was the screen protector at first

Could anyone confirm that the touchscreen input is lagging? I'm using the app 'art canvas' with the spen and when drawing a line around the screen it misses parts of the line, try it and please let me know if it's supposed to act that way.

The pen is the worst here. I even removed the first screen protector still have touch registration issues. Interestingly test apps such as YAMTT work fine. Did you also test the touchscreen with a similar app?

Multitouch is broken, bad build quality or something else?

Oh look, another thread that I have to make, as you can see, I am really enjoying this phone right now. Anyways here is the thing: Download any multitouch testing app(I used Yet Another Multitouch Test). Put your phone on a flat surface. Try to use more than 2 fingers without issues. In my case, trying this will make it not detect atleast one finger properly. Now press and hold the aluminium frame of your phone. Multitouch is now fine. While I'm holding a phone in my hand, multitouch also works fine, so this is only an issue when i put the phone on a desk or bed. Could it be that digitizer isn't connected properly? Or could it be something else? Do you also have such issues with this phone? What could be done to fix this?
Update: after more testing i have come to the conclusion that the reason for such issues is aluminium frame of the phone. Weird, I would like to know if this can be fixed in any way tho

Definitely a hardware issue/fault. The best thing to do for now is to send/bring the phone to Sony for repairs. If you hadn't unlocked your bootloader and your phone is within its warranty period then it should be covered by warranty but if not, just be prepared to spend, hopefully its just the frame and the digitizer not being aligned and not the actual screen itself with the problem
Godspeed

Alright, but have you tried this out? Because I've seen a lot of Z1/Z1 compact threads that describe similar issue, I wonder if all devices are faulty like that or just some?

I managed to get to 5 fingers. Couldn't fit more since the screen doesn't detect if fingers are to close to each other so I had to keep them a bit spread out.

Yea but, it's not about just recognizing fingers, can you try drawing 3 straight lines with 3 fingers when not holding a phone? This is where the issues usually start, trying to swipe while not holding aluminium frame of a phone

I've just tried it with a multi touch tester app and it's absolutely as you've described. Additionally I've had some issues with phantom touches lately so maybe it's somehow related to this.
please do let me know if you somehow find out the cause of this or find any 'solutions'

Will do. I've heard people have had their screens replaced for this and issue still persisted, so I wonder if it depends on screen manafacturer. You see, Z1/Z1 compact models are shipped with either JDI screen or AUO screen. I have JDI. Of course, we will need some people here with AUO screen to do the testing.

mine is AUO

Then i don't know
