General :: Way To Improve Touch Screen Response
Jan 31, 2012
I have a Samsung Galaxy i9003(SL). I think there is a problem with touch screen response speed.Although Galaxy SL has a 1 ghz processor and better gpu than SonyEricsson Xperia Mini, It seems that Xperia Mini is faster when we're talking about touchscreen response(messaging,sliding the menu etc)
After trying another lower resolution(i mean lower than galaxy sl) android phones such as galaxy ace, galaxy gio or android sdk(because you can set any resolution with it) I realized touch screen response is related with resolution.
Lower the resolution faster the touchscreen response gets.I found this really annoying. You're paying much more to get a faster and big screen phone. But what you get is slower than the cheaper ones.
Do you think is there a way to lower the resolution on samsung galaxy sl to get a faster response? I found a way to change it but instead of changing the resolution(like 800x480 to 640x360) it changes LCD density and that is not what i want because it does not affect any response speed. or maybe another way? Changing kernel, improving gpu etc?

so after a week and a half of having this phone the screen response has started to lack. when I first got it the phone was almost to fast for me. now it seems like it has slowed down a lot and the screen sensitivity is almost on par with my old LG Voyager. its almost like a hit or miss with what I touch.could it be that I have a screen protector on there?

I am working on a game that displays its graphics through a modified SurfaceView.The game scrolls around a map based on the location of the main character.That all works fine.I am trying to add a feature to the game that allows you to touch the screen and drag the camera around to see other parts of the map.This is where I am running into trouble.The game's SurfaceView overrides 'public boolean onTouchEvent (MotionEvent event)'to call another method in the game's thread which handles the events.Sometimes, this works fine (although the frame rate drops significantly while the screen is touched).Other times, there will be a delay of several seconds before the game responds to a touch event, during which time the game continues, but the user loses all control.During these delays, a message sometimes appears stating that my activity is not responding, and giving the options to 'Force close' or 'Wait'.If the user selects 'Wait', the game almost always resumes right away, but these delays are obviously not acceptable.The delays occur only the first time the screen is touched after the game is started.Once the game has resumed after a delay, the touch events work just fine again.

on Android devices I experience lag between actually touching the screen and the event when the application knows about this touch (about 0.1s). Is this a mandatory for Android in general, or is this the limitation of hardware I have tried, or is this a limitation of Android versions prior to 4.1 (I haven't tested JB yet)? I have tested several musical apps for Android and they ALL lag. I press the virtual button, and only after a gap I hear the sound, which makes it all unusable in realtime. When I tested iOS based devices the response was just immediate. So I'd like to know if Android device can ever do such things at all, or I shouldn't expect that?

I have a note 2, and the touch buttons next to the menu button responds late somtimes, or it wont work at all sometimes. What could be the prob?
Normally it works fine, and my ram are under half when it happens so it is not ram. Also everything else works even tho the touch buttons don't.

1) when press the home or power button to screen on, it is quite delay?
2) when I want to end called, I must press power button, the phone screen only light on, then must double tap to unlock screen, only can press the end button to end call. Is there got any easy way like other phone? Like the phone can auto light on when take away from ear?
3) I have using the software update to update, but still the same, just want to check DXLG1 and DDLI1, which is more latest? DDLI1 is belong to which country firmware?

Just a quick question about the Captivate. I just got myself an HTC Aria and I love how easy it is to use the touch screen on it. Its extremely responsive. Now my sister has the SamSung Instinct on Sprint and the touch screen is horrible compared to HTCs touch on the Aria. Im thinking about taking the HTC back to AT&T and getting the Samsung Captivate. I am just worried about the touch screen on it and if it will be like the Instincts? If the touch is as good as HTCs Ill get it. If its not, then Ill stick with the Aria because despite its size, its an extremely fun and responsive phone. Any thoughts?

Back when we all found out about the bad gps on this phone there was talk to file a complaint against att for false advertising of gps capabilities with the Captivate. Well, I was pissed and went ahead and filed the complaint. I received a letter in the mail a few weeks ago that the FCC had received the complaint.Today, I received a response from ATT in my inbox.

I'm getting used to the touch screen but it doesn't half stress me at times. (My fat Lincolnshire sausage fingers certainly don't help)I often struggle with the keys on the edge of the screen. I don't know why that would be. Oh, and the most strange phenomenon is when a left hand finger, despite trying repeatedly, fails to click a button so I try my right hand and it works first time (or vice versa). Anyone else find this or should I book myself in at the lunatic asylum?

I have a Qware TB-9718D tablet (rebrand of ployer-momo11-speed) with RK3066 CPU and Android 4.04.
I've installed the CWM-ROM-Ployer_Momo11_3-0-8_M1_software_chinese-version_4-2-2_20130425-4-2& CWM ROM (Android 4.2.2) on the tablet and it boots just fine.
However, the touch screen does not seem to work anymore with this ROM. I have tried two touch screen fixes (which were suggested on another site): one of which was the 907c_compatibility_1.2.0.zip
How to fix the touch screen with this ROM? Could I for example extract the touch screen driver from the original ROM's lib folder and use it in this new ROM?

I was using my phone (droid 3) and the app I was using force closed, my phone lagged for a few seconds and then I just put it down so it could catch up. While waiting the screen timed out and when I went to use it I could not unlock it. I can press the button on top and it will turn the screen on or off, and if I hold it it will bring up the power off menu. I tried to call it, and it went through. I got the normal screen to answer it, but I could not answer it. After I hung up I got the notification for a missed call. Everything seems to be working, my screen just does not respond to a touch. What should I do?

The touchscreen is not responding randomly the device itself is functioning fine but the screen is not use-able. The simple turn off and on the screen fix the problem for a few minutes but then again is not working, and is frozen in the lock screen so i have to do the off/on trick few times to make it responsive. I tried the stock rom the modaco rom and now i am using AOSP JELLY BEAN 4.2.2_r1 but it is all the same. Every time i flashed a rom i did the full wipe. Sometimes is even frozen in recovery mode. It aIso sometimes reboot when it get frozen. I have 1.4a loader and i tried with all the twrp versions now i am on 2.5

I am having big troubles with the touch screen of my Samsung Galaxy Exhibit II. Everything worked smooth since 1 year, and 2 days ago suddenly the touch screen stop responding. The phone works, I receive calls but I cannot answer since I cannot swipe. All the side button works, but the front button on the screen (menu, option, back and search buttons) do not work at all. I tried to reboot but nothing. I took sim, battery and microSD out for one entire night and then rebooted in the morning (without sim and microSD) but nothing. I also rebooted the same morning with sim and microSD but nothing. I ended up to try a factory reset even if I dont have a backup but I figured out I cannot do it because when I reboot and press volume up and power button then I cannot press the menu bottom when I see the robot with the box since the menu bottom does not respond!

My son dropped his Nexus and of course it cracked the glass. The crack is on the side not affecting the view of the face at all and it has a couple of chipped pieces. I was just going to try filling the area with something like silicone, JB Weld, or auto windshield repair.
What I can use that will not interfere with the touch screen. I'm thinking that silicone might be too much like "skin" touching that it might not work.

I have a Chinese touch pad. I tried to install several custom rom (CM9, AOKP, etc ...) as well as Roma manufacturer of tablet very similar to mine (A90 Ampe, Sanei N90, etc ...).The flash firmware or install via Recovery is done very well. The android starts very well. However, the only problem I have is that my touchscreen is not responding.Indeed, I have to connect a mouse to use my tablet.
I love and I think it is possible created a sort of patch to apply via the recovery or via command ADB with the "drivers" of my touchscreen from my original rom.
I already recompiled the image of my ROM so I have access to the entire file structure. But I do not know enough to identify which files that match the drivers of the screen.

how to edit the touchscreen driver? Problem is on the Asus Transformer Prime TF201 none of the replacement touchscreens have a proper X-axis, they're all inverted. I wanted to try my hand at editing the driver(s) that control the digitizer.

i got a brand new S3 In december 2013 , i dropped it an it broke ( both touch and LCD ) I got them replaced by a authorized service . It worked fine 2 months , Two days ago some problem appeared, Touch screen stopped working propperly , it worked only for short periods of time. Now if i press really hard on the right hand corner (Above the return arrow) it works Perfectly ( as long as i keep my finger there) but sometimes it works fine after reboot but in the end it stops (No signs of cracks or damage) , i had CM11. What i've done until now :
-Deleted CM11 and added 4.1.2
-Took it appart and checked the ribbon ( fine)
-Hard reset
- Dummy file generator
Everything works on it buttons ,Before the freezing screen flashes a bit .

I was wondering if it would be possible to emulate touch controls with a USB keyboard similar to how you can emulate touch controls with a PS3 controller using the sixaxis app. I want to do this for some rhythm games.

I recently cracked the digitizer on my Asus Padfone 2 Tablet and I got a replacement digitizer from Ebay.
However, after replacing it, I noticed the x-axis is flipped.
How can I reverse it? Can it be done via editing some files?

I have 2 year old kid he loves to watch cartoons or videos.
Is there any which blocks the touch and home button. On the iphone there was a application like Incarcer where you had to press volume and down to enable home and touch again.
Is there anything similar for an android phone. Got a galaxy s1 9100 and galaxy s 9000.

So I did a water test on my Moto G the other day because it's supposed to be "water resistant." It survived the first day of the water test, but the next day, the touch screen isn't working.

I have a Ascend P1 running ICS 4.0.3, and while the phone is amazing (much better than my previous Vodafone Smart II ), it has two issues that really bother me, first is the touchscreen not being calibrated correctly, I'll try to describe it properly.
In the middle of the screen everything is fine, but towards the bottom and top edges the touches are not exactly where my finger is, at the bottom the touch is registered a little lower from where my finger actually is, and at the top it's the inverse, the touch is registered a little higher, and this "offset" increases as the touch aproaches the edges of the screen, kinda like the sensible area is smaller than the screen but is mapped to the whole screen.
And the second is the audio volume, it's too low with the headphones.A couple days ago I tried a Jelly Bean rom (supposedly from the manufacturer) and this two issues where gone, but on the other hand brought some others that are not the case right now.
how can I address these two issues?

I've came up with a concept of new type of "keyboard" for touchscreen devices (target: mobile phones), the tests went really great, and I am now patenting it.I'm not allowed to post links, please search "swipewheel" in youtube.

I dropped my phone and the screen won't turn on and doesn't respond to touch.The insurance company is picking it up tomorrow (*hence the urgency) and would like to get some stuff off it. Most stuff is on my exsd, so I'm not too worried if I have to wipe it, but would prefer only to wipe it once everything is off. I'm rooted and have a custom stock based rom and cwm installed.
Is there any way of doing this? I have the lock pattern enabled so when I plug it in nothing shows up.
If not, then how would I wipe it?

I'm trying to set up a tasker profile that will save some time (and my phones hardware...).
In a nutshell: When using a particular app, I would like the screen to turn off after a short period of time, but (and here's the bit I can't figure out) allow it to be unlocked just by touching the screen (i.e. no hardware button presses required). Is this possible with Tasker?
