Samsung Epic 4G :: Touch Screen Lag
Sep 6, 2010
Ok time for the next issue with this phone. Has anyone noticed a general lag between touch screen presses and actions/sounds?
The best examples are:
1) I type fast, and keep the click sound when I type. I can literally hear about a 1/4 second to 1/2 second lag between when I press the buttons and when the sound clicks.
2) Download any free piano or drum up and try to keep a steady beat. There's a nasty lag between when you tap the screen and when the sound comes out.
For comparison, the keyboard and piano app on my old iphone (3G no less), work perfectly. And my iPad is wonderfully smooth.
Is this a software issue, or a problem with my phone?
Musical Lite is a good sample program for free if anyone wants to try this out.

Does anyone have the same problem, I just got my Epic today and when I plugged it into my computer to charge it the touch screen doesn't work. Any workarounds that people know of?

Does anyone else's touch screen become unresponsive when the Epic is being charged? My touch screen gets glitchy and only responds to a fraction of touches.
I just received mine yesterday and I've already spent more than 6 hours trying to troubleshoot this issue. Most of the google searches that I've found have to do with cheap 3rd party chargers, but I'm using the OEM Samsung charger.
I thought it might be the charger, so I went out and purchased 4 different chargers today, but none of them fix the issue.
I also ordered another Epic for my wife at the same time, and her Epic has the same problem, which suggests that it's not a defective phone (unless they both came from the same batch).
To confuse things even more, I've been able to isolate 2-3 outlets in the house where this problem doesn't happen. The problem also doesn't happen when I charge at work, through a car charger, or via USB from the laptop.
I'm inclined to think it has something to do with the outlets in the house. However, I've never heard of any issue like that and the house is relatively new (built in '98).

This is a HUGE problem!
During a call, when I put the phone by my left ear, my ear and/or my cheek touch the screen, and though one would expect the buttons on the touch screen to be disabled during a call, when held against the ear and the face, I keep accidentally hanging up calls or in some other occasions, muting, having frustrated monologues to myself, thinking that the other person is ignoring me...
I mentioned using the left ear, because, it seems to have always happened when I held the phone by my left ear and not when I held it by my right ear.
I'm trying to find a more elegant solution, as dropping numerous calls is not an option. (today I dropped more than 15 calls). Any suggestions?

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?

I got pretty good guessing the touch buttons one they time out, but still annoying as I did miss sometimes.Well just now, I decided to do something about it.A real quick poke through the phone revealed a very easy fix.The path is here.Settings[Sound & Display[Keyboard timeout[Same as Screen timeout my screen timeout is 1 min.As we all know, and I verified this. The keyboard backlight only turns on when the slider is open. Now the touch-sensitive buttons will infact stay lit as long as you would need them, while the screen is on .Life just got a little easier B)

I like many of you have been waiting for months to get my hands on the epic. However when I bought one, the battery life was insanely unusable even after 4-5 days. So I finally returned it for a new on. Well find out over the next few days how the battery performs. But the new one has capacitive buttons that barely respond to touch. Particularly the home key and menu key. I've read of a bunch of people having similar problems. Are we just a few unlucky people who happen to be on the forums, or is Samsung having serious Quality control issues here?

I'm pretty sure my home screen would do landscape with keyboard closed the first couple of days I had the phone and now it wont do it unless the keyboard is out. Anyone else have the same issue?

Ok the Epic is getting headphones. But does the Epic have the puzzle lock screen? FM radio? And does the music player have that cd juke box feel?

Sometimes when I shut the slider quickly the phone shuts down. Then today it did it when I set it down on a table, and when I turned it back on the battery went from 42 to 12 percent. I then reset the phone and it was at 24 percent. Is anyone else having this problem? Could the battery just be losing contact?

I've had my Epic for about a week and have noticed that from time to time that the screen flashes VERY briefly to the home screen/lock screen when inside an app.
It happens when I'm in the browser, email app, etc. There does not seem to be any rhyme or reason behind it.

Sometimes when I hit the screen/power button the screen will stay black and i can see the menu bar up top fine but all else is black. If I hit the home key then all lights up fine. Then sometimes Ill hit the button and it works fine.

Went into test mode to check out the battery. And through my curiosity went into the 'touch-fw update', and now I can't use my phone. I have the touchscreen lock so can't unlock it, otherwise maybe I could use the keyboard or the optical joystick to use the phone. Is there any way to fix this? I might attempt a hard reset, but saw on another forum, that it's unfixable. I bought it at Best Buy and they aren't even open tomorrow, would another Best Buy or Sprint store exchange it if I can't fix it?

Is there any way to turn up the sensitivity on the touch screen?It seems decent enough, but it is no where near as resposive as my old iPhone.Why? It just seems like I have to touch everything on the screen twice.

First of all I searched and couldn't find anything on this. Is anyone else having an issue with the screen not being very accurate? The on screen keyboard seems fine for me, but choosing something such as a link in the web browser is a little off on my phone.
An example would be opening www.wsmv.com (my local news), then trying to click on news on the left hand side...instead of news, it will choose what is below it (in this case weather). I thought it was my fat fingers, but others who have tried my phone experience the same issue. I was just wondering if it was just me? Any way to calibrate the screen?

For example, I can scroll a page but when I stop and hold my finger on the screen, it moves about very jittery even though my finger is not even moving. It can be annoying at times when I want the screen to be steady.
Has anyone else had this problem? BTW, I do have a clear screen protector on my screen, could that be part of the problem?

Is there such a thing for the HTC desire? also, is there a app that lets you see how many multi touch points the htc desire has? i saw some youtube vids where that have this app and they put as many fingers as they can on the screen and scribble around.

As far as I understand, Android and the Galaxy touch screen is not meant to be calibrated; at least, there does not seem to be a user interface for doing so (this is also true of the tilt and compass sensors, and yet various apps include their own calibration methods.)
The trouble is that I frequently --perhaps 40% of the time-- hit the key to the right of the one I meant to type. That is, I get an "M" instead of an "N", a "Z" when I intended to shift into uppercase, and so on. One might argue that I just need to get used to this teensy keyboard, but I might argue that a good user interface should get used to me. Is there anything that can be done?

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?

Even knowing our Epic 4G's have GORILLA GLASS, will you be using a screen protector? Personally, I'm leaning towards not...

Okay so here is another strange thing I noticed with the update.2 of the 3 phones that got the update now have a little home icon on the bottom of one of the touchwiz screens when you are in the edit mode. This page with the home icon can now be moved to whereever you want it in the positioning of the 1-7 screens you have and when you click on the "home" key at the very bottom it will go to that screen. Previously there was no home key and your home screen was either the middle or far left screen depending on the number of screens you had.
