[Q] Touchscreen sensitivity. - Xperia SP Q&A, Help & Troubleshooting

hello, a few days ago my xperia sp was depressed and tried to kill herself by throwing from a height of 90cm. The result was a broken touch screen, which cost me about $ 90. Since it is not difficult I myself installed the touch screen.
However, after installing the screen, I noticed that the sensitivity is horrible, the touchscreen was a little difficult to operate, but not impossible. I even can use day to day, but it is remarkable the difference in sensitivity between the new touch screen and touch screen broken.
What can I do to improve or increase the sensitivity of the screen? Thank you.

Try calibration touchscreen via some app.

you could turn on glove mode. that would increase the sensitivity.

Was it an OEM digitaliser? You could try cleaning the contacts. Someone else on here has just experienced the same thing he reported a big difference between the two screens and also a discrepancy between the serial numbers on the digitaliser.

Change it if it gives you problems
I'll change mine again for an oem version

holy ship, more $90 dollars spent on this phone. Planning to buy a Moto G instead.

Is there any way to make the capacitive buttons more sensitive

My friends droid needs the lightest touch but my captivate needs my whole thumb and half the time it doesnt work.

I found it to be much more responsive to the pads of my fingers. Seems the harder (more calloused) finger tips have trouble getting a response. It is frustrating because I find myself double tapping out of habit now. It would be great to change the sensitivity.

yeah i always double tap and now with this laggy froyo i end up going back too far, is there a solution to make it more sensitive?
Out of curiosity I grabbed my sons phone and lifted the screen protector. The responsiveness is definitely increased without the screen protector. Arguably it is a very crappy throwaway protector but it could explain some issues. I have a skinomi skin and am not taking it off for testing purposes.
Do you happen to have a protector over your buttons?

I have an invisable shield on mine, I tried the ones on display at att and they have the same responsiveness

[Q] Screen cracked, touch not responding properly.

Hey everyone.
A few months ago I dropped my phone for the first time. It turned out that the screen had gotten a large crack down through the middle, running all the way from the top to the bottom. I tried using it, and the touch capabilities didn't seem to be affected, so basically it was just cosmetic at first.
But this afternoon, after having used it lightly since morning without issues, the phone suddenly started responding weird to touch. Whenever I touch the screen, it registers touches all over the screen, and I'm not even able to dial in my pin code after rebooting.
Does anyone have an idea what might have happened, what is broken, and how much it will set me back to fix it?
BTW, the phone arrived with a red pixel, I noticed it once when booting up, but thought it was just a bug or something. Later I found out that is actually a fault with the phone, and most companies have dead pixel policies, I'm wondering, is it possible to return the phone for a new because of the red pixel?
Thank you for your time.
I think it will be a little hard to prove that dead pixel after being cracked. If you have some skills, you can change it yourself, its not very hard and you can find the screen on the internet.

That does sound good, but aren't the glass (The outermost layer) and the touchscreen two different things entirely?
Thank you.
Well what do you know, it started working again! Well, atleast for now.
Thanks for the advice

...I'm going to go out on a limb here and say it's the huge crack down the middle of the screen? :good:
Seriously, though.. capacitive touch-screens measure changes in the resistance across a thin layer on top of the glass. So if you bend it somehow, or damage it (say, stretch it because the glass underneath cracks), then the resistance won't be picked up, or it will be registered inaccurately. So it might work for a while, or work reasonably well. Know a guy who smashed his iPhone.. sat on it, actually.. and it worked with "cracked" glass (that was held together by the layer on top of the glass, right) until he bought another iPhone. *shrug* He talked about it a lot, but it didn't seem to really make a difference on the actual phone.

[Q] Replacement screen

Anyone know where to find the amoled screen replacement part. Phone dropped from table & hit the ground in the upper corner. Screen is shattered, touch still works though. Lcd intact but expected it to be stronger still. Replaced the screen on my Ace & was pretty easy to find at 30$. This one cant seem to find.

Nexus 4 vs Optimus G vs Iphone 5 IPS display

Hi guys, as you guys all know, those 3 phones I mentioned all have IPS technology for the display.
And as far as I know, the nexus 4 screen sensitivity isn't that great compare to other devices such as my Nexus 10. I could use the back of my finger, which is the nail, to navigate the screen while on the nexus 4, I have to really "touch" the screen. what that means is when I touch it light enough that I can feel the screen, the nexus 4 still won't recognize it until i press it a bit further. :silly:
I've been told this is related to the hardware of the IPS itself? :silly: but i'm not so sure since there's a mod to increase screen responsiveness. I tried it and it works, but the delayed when booting really bugged me .
So anyone with an Optimus G or an iPhone 5? how is the screen sensitive to you guys? can you touch the screen light enough that you can feel the screen but the Nexus won't feel your finger?
If it's more responsive then can we somehow pull the touch driver from the Optimus G to our Nexus 4?
I have Iphone 5 and I never have to put any pressure on the screen for it to work. I barley tap the screen... Even though I havent had a nexus 4, I've had galaxy s3 and I can say iphone 5 screen is more sensitive than s3 screen
None of these phone can recognize the nail finger.

yea but they use a different technology. i believe it's usual LCD. unlike our nexus which has IPS technology.

hmm.. well that's even more interesting because s3 uses super-amoled. which I assumed to be more sensitive since my HTC one S is more sensitive than my nexus.. and if iphone 5 screen is really sensitive with IPS how come our nexus 4 sensitivity is so bad? really hope google would fix this..

The display technology doesn't matter here. It's the digitizer that makes the difference.
From my experience, when you just tap the screen on the nexus 4, you have to press quite "hard" to get it to register the touch.
If you start swiping around, even the lightest pressure will be enough. Even the fingernail works if you do it that way.

did you try it on yours? mine doesn't respond to my fingernail lol :silly: so is there any differences in sensitivity between Optimus G and Nexus 4? do they use different digitizer then? both are manufactured by LG and very similar in terms of hardware wise Any Optimus G owner out there? or had a hands on experiences with Optimus G?
My nexus 4 is very sensitive to touch, I barely need to touch the screen (just float over it) and can use it with the back of my fingers (fingernails). It's been much more sensitive to touch than my Galaxy Nexus ever was.
My N4 is one of the latest batch, maybe improved? I don't know but it's been faultless so far. Also find the screen has nice rich colours almost on a par with the GN, haven't noticed any washed out effect like some state, same goes to my friend who bought one at the same time (1 month ago).
I'm on unrooted stock btw, tried a few custom roms, but find stock better for me (at the moment).

that's great to hear me and my GF bought the nexus 4 right after new year. Both are about 1 month away from each other too. and still the same below par sensitivity. hmm.. maybe google did fixed it hardware wise? if so i really want to sent my phone back lol..
I think custom kernels improves the sensitivity of the screen

I highly doubt it. I got one of the newer models (301k) and my screen sensitivity is awful. Yes if you press it normally most of the time it will work but if you a very light it isn't sensitive at all not compared to my one s. That being said I flashed the old touch driver back (e015) and my nexus 4 is as sensitive as an iphone now. Had the driver for about 2 weeks and I would never go back to the current touch driver that comes with 4.2.2 (e027) Hopefully google fix this but I'm doubtful. The people that say they have amazing sensitivity imo are speaking out of their backsides. They haven't made the devices any different, the screen sensitivity is a SOFTWARE issue and not a hardware issue. This is a link to old touch driver thread. http://forum.xda-developers.com/showthread.php?t=2163924 It's like a different device!

are you sure its not ur knuckle and just the finger nail? It should, according to design, not register hard things such as finger nails. (unless you have keratin deficiency in which case ur nails might be as soft as skin)

His nexus probably grows wings and flies when he puts it into airplane mode as well. People exaggerate so much sometimes!
It's just fine on my nexus to be honest. Don't know what everybody is on about

as far as i know, there isn't a single touchscreen device on the market (past or present) that will register the fingernail itself.
that said, my Nex4 is from the second batch and is quite sensitive to the touch. some of the touch responsiveness issues could be due to a screen protector too.

Mine does!!! Maybe urs is defective.
But also there are ways to improve responsiveness!
if i remember rightly finger nails only work on resisitive screens

are you sure? last time i checked it didn't work with just the fingernail (no skin). that would be like using an old stylus from a windows phone 5.5/6 device (resistive screen) on a capacitive screen. i highly doubt that works.
Funny thing that I was so disturbed about was how badly insensitive the nexus 4 was compared to my i9300 (gs3). I could use my fingernail and the lightest touch to swipe the screen with the s3. So these things are possible.
I also flashed the kernel months ago and it improved things slightly, but nowhere near what I'm used to. Only problem with that is how much longer it takes to boot and be responsive. Same with TWRP...you have to wait a while to use the device.

A strange behavior of my Samsung M10

Hello my dears,
I have a strange behavior of my Samsung M10 that I can not explain, please watch this video:
https:[slash][slash]www[dot]youtu[dot]be[slash]X-0ouhTM7Bw
Please replace "[slash]" by "/" abd "[dot]" by "." :silly: (i can't poste links, new member)
as you can see on the video there is a multiple clicks and slides on the screen of the phone by himself (there is no screen protector i took it off),
About the white dots : i activated an option on the developpement menu of the phone that let us see the position des clicks on the screen.
please someone has an idea about what causing this behavior ?
Did you throw it? or was is dropped from your hand? Or any heavy Pressure on the screen?
Probably your phone got heavy pressure on the display that just cracked the brain of the touch screen.. Better go to an official Samsung customer care center/service center. ☺
It may cost you about 55$ getting a new touch screen.

Yes. The rubber bands forced pressure that damaged the touch..
thr touch screen's price is around 55$.. perhaps they took the service charge or other charge.. 67$ is okay..?
