Android :: Touch Screen Response Delay

Feb 6, 2009

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.

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?

General :: Touch Response Lag

Nov 9, 2012

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?

Samsung Captivate :: Touch Screen Compared To HTC's Touch Screen?

Jul 17, 2010

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?

HTC Hero :: Weird Screen Response

Nov 9, 2009

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 found the settings to adjust the delay on the screen itself blanking, but when using the phone in the dark, the backlight behind the home, menu, back, etc, keys turns off too quickly. I might be reading and email and want to go back, but by the time I have read it, the keys are dark.

Is there a way to adjust this setting?

Whenever I am using any app and press the home button, the home screen blacks out for a few secs and it takes around 10 sec to get all the icons back and before I can start using my phone again. I am using a non rooted mytouch 3g.

This problem does not happen if I exit an app by pressing the back button. It becomes very annoying at times.

Motorola Droid :: Touch Screen Works On Half The Screen

Sep 11, 2010

I bought a new droid for $20 haha lucky i think until i notice that the touch screen only works for the middle of the screen to the left so if yu cut the screen into thirds only the middle and left work assuming that yu cut it from top to bottom with the lights at the bottom for the home button etc. I opened it up cleaned all the flex cable with alcohol and waited for it to dry and it still does the same thing so my question is = do i need a new digitizer or is it a software problem or something that i dont even know?

HTC EVO 4G :: Screen Rotation - Delay When Switch From Horizontal Position To Vertical Position

Sep 29, 2010

On my htc i was looking through display, i see g sensor calibration and i perform this calibration and after i do so the screen seems to have a delay when switch from the horizontal position to the vertical position. its weird because when i switch to the phone horizontally it switch normally and responds fast. but when i switch back to vertically it takes almost 7 seconds to actually switch back, sometimes it switch within 2 or 3 secs but never as quick as switching horizontally.

If you're already updated, shut down and repower (soft reboot) should do the trick. I actually updated my phone and after it started to do this. I restarted the phone plenty of times i even took the battery out for 30 seconds. It only does it when im texting on the browser, basically everything but the camera. He camera screen rotation is perfect. I even rooted the phone but i havent figured out how to use the root to fix the problem. Should i do a firmware update? Because i just did the htc software update.

HTC Desire :: Locking The Screen Via Touch Screen

Jun 19, 2010

Anyone know of a widget to simply lock the screen or put into sleep mode by pressing something on the screen rather than pressing the power button on the top of the phone. Tried looking around and unless I'm missing something (I am particularly good at missing the obvious!) there doesn't seem to be anything that does just that. Anyone know/come across anything that will do this? Does anyone know if this might be included in 2.2?

Android :: Touch Screen Slowdown

Mar 26, 2009

I am having a problem with the touch screen in that whenever the screen is touched, it causes significant slowdown because of the large number of callbacks that are being made. I have read in this group about throttling the UI thread, but this does not seem a good solution and i can't believe there isn't a better approach?

Android :: Touch Screen Data

Jan 20, 2010

Alot of android phones use the capacitive touchscreen technology. I was wondering if there is away to access any sort of information related to this sensor.

In other words I want to get the voltage potential related to the distance that you push down on the screen.

I know this is probably really deep into the hardware technology and it's probably proprietary, but I want to know if someone has figured out how to access this data or if there is a way around it.

Android :: Get Raw Touch Screen Data

Oct 21, 2010

RT Actually I wanna detect the shape of touch point, i.e. the shape of finger touch on the screen

Seems that the only information I can get in touch event is the size of the touch point(by event.getSize())

By the implementation of the screen, the shape(and pressure of each point in the shape) of the touching finger should be the first raw data that the hardware can detect

So, how could I get these raw data?
