"Project Butter" is Google's name for the UI latency enhancements implemented in Android 4.1 Jelly Bean. Any Android device running Android 4.1 or later will have those enhancements. Remember, though, that software is only part of what makes an interface smooth and 4.1 isn't a cure-all for lag. Slow hardware will result in a slow UI regardless of the OS. ...

Yes, capacitive screens just need something that alters their capacitance: something conductive or a dielectric. As per usual, Wikipedia has more information.

I have a T-Mobile G1 (the first Android phone) that's a few years old now and sensitivity on the touch screen is still intact. If you don't treat your phone well it is likely that over time you're going to damage it or the screen can get so dirty that sensitivity might decrease, but it is not an issue with the touch screen technology. Any phone that is ...

Well the hardware needs to be properly aligned, so that where it senses your touch matches up with what you see yourself touching. There are also general algorithms the system applies to make decisions about where the center of your touch is, since your finger is not a perfect point, and so on. Finally, and app needs to decide what to do with a touch. ...

I also had this issue recently. I only had one, vertical band, but it still affected use, mostly typing. I demonstrated the issue (seen below) and contacted the [ebay] seller. They promptly classified it as defective and sent me a new one. This will most likely be the solution to your problem as well. As I did, I would use a drawing program to verify, and ...

You can try to diagnose the problem yourself, or at least get a little more info by turning on a couple of developer diagnostics. In Settings, scroll down to Developer Options. Under the "Input" section, check "Show touches". This will cause a small (white) circle to show on the screen where ever you touch it. If you don't see the circle (which might ...

Some devices, like the Motorola Xoom, the Sony Ericsson Xperia Active and the Galaxy Nexus, have an air pressure sensor built into them that measures the barometric air pressure. I have the Barometer HD app installed on my Xoom which seems to give roughly the same reading as my Suunto electronic barometer. Support for a barometer pressure (and other ...

To answer you questions: Could this be caused by the screen protector? Possibly. Take the screen protector off and see if the problem persists. My screen protector doesn't affect the functioning of my screen at all. This is going to depend on the particular screen protector (I'm sure there are cheap, bad ones) and the particular phone (they all have ...

On my Droid there's actually a proximity sensor that disables the screen if anything is too close to it. On the Droid this sensor is up next to the ear speaker so that when you put the phone up to your ear it triggers the proximity sensor. What model phone do you have?

On my phone I can click the power button to turn off the screen, so no buttons are there to be pressed.

Resistive touch and Capacitive touch will operate the apps the same way, the same way a laser and a mechanical mouse are two different technologies designed to do the same thing for the user. Both have their advantages and disadvantages, for instance try using your capacitive iphone screen with gloves or finger nails, it wont work. A capacitive screens are ...

No there is not a way to do this for android, unless root access allows this (which it may). To do something like this you would have to change the size of the capacitive recognition. The screen is not pressurized, but rather interacts with the electrical interference of the screen. Tapping lightly won't do anything other than reduce the amount of your ...

If its totally un responsive then you need verify once your harware whether its an exact replacement or not as HTC Wildfire S digitizer comes in two variants With Chip Without Chip So match it with old damaged one and if they are same then the hardware will be faulty and you will need one more replacement.

I am the author of MacroDroid and I have some experimental (root only) features in development to do this but have not yet released anything in the public version. I have an action called "Launch and Press" that allows you to launch an app and record a series of touch events and they will then be played back at the same rate. Basic touch events work ok, but ...

Open your settings menu and go all the way to the bottom, open Developer Options. In the Input section, find the options called Pointer Location, and check it. This is a feature for developers that shows the raw data from the digitizer. Move your fingers around on the screen, and watch what you see, if your finger seems to disappear from the screen, ...

Have you tried Google's Quickoffice? It detects numbers (and underlining them), and lets you click the number to open the dialer with that number.

Here's a video on how to create a capacitive stylus for free (as long as you have an anti-static bag laying around). From the page: In this video we show you how to create a free capacitive touch screen stylus out of a common piece of antistatic film. As many people know capacitive touch screens use an electrical impulse created by the operator's body ...

The way I solved the issue to my satisfaction was to buy and install the WidgetLocker Lockscreen app. This is an awesome little app that basically allows you to replace your lockscreen (and incoming call screen too) with something customized. I just have one horizontal slider to unlock the screen now, and it has completely eliminated accidental screen ...

Capacitive touchscreens found in modern smartphones don't wear out, physically, because they're solid-state technology behind a piece of glass. Practically the only way to destroy them is to build up a goodly amount of static electricity and then touch the screen -- if you're deliberate about this, it might zap the circuitry, but it's not specific to ...

Thin styluses are usually for resistive screens, they don't work with Droid X's capacitive screen. The difference between capacitive and resistive touchscreens

There is a lengthy discussion about this on: http://androidforums.com/droid-support-troubleshooting/87515-my-droids-touch-screen-going-crazy.html The main point seems to relate to either oil and dirt covering the screen and/or heating up issues from dirt within internal components. There are some suggested solutions such as carefully cleaning the screen ...

Are all touch-screens on modern devices multitouch capable on hardware level (if software supports it)? This is more or less impossible to answer without spec sheets for every Android device that has ever been created (within whatever timeframe you consider "modern"). Very broadly speaking, devices from major manufacturers over the last several years ...

Give androidscreencast a try. You may already need to have USB Debugging enabled for it to work, but you've said you already have that enabled, so should be ok. It just needs a USB connection to the phone and goes over the ADB protocol.

It is true. But not all touch screen phones work well with this. The capacitive touch screens that we find in most android phones these days work by detecting electrical disturbances from our body. The 'sponge' used in these DIYs are electrically conducting foam and they transfer the charge of our body through it, thus registering touches. On the other ...

I've developed such an app called RepetiTouch. It's currently in beta stage and aimed at developers, but a limited free version is available here. However, it needs a rooted device running Android 2.3 or later. As far as I know, currently no other app with this functionality exists, but there are some tools/scripts providing such features using a computer ...

So I've had this same problem for the past month. There is a 1cm or so high deadzone that spans the width of my screen just about lower than the midway point from top to bottom. It is mostly always there, but some (seemingly) random times it goes away and all works well. My troubleshooting led me to this: If it's hardware, it's only because the software ...

I have a Pogo Stylus which was originally meant for the iphone although I see they have an Android version now. It works ok, but I feel like I have to push down harder than I want to to get it to work. It is accurate, more so than my finger, however if I don't maintain enough pressure when drawing a line for example, there will be gaps in the line. I have ...

My Motorola Droid is as sensitive now as it was in October 2009. At least I don't notice any appreciable loss of sensitivity. This is my daily carry/drop/reflash/abuse phone, so if there were going to be some loss, it would happen by now. In my PalmPilot days, I could definitely tell a difference after about a year, but that was probably due more to the ...

I had the same problem with the HTC Nexus One and it was directly related to heat. Whenever the phone got too hot the touch screen would flake out. Charging the phone makes it heat up, the worst time for me was when it was in the car dock, heat from charging and from the screen being on all the time. When ever it did this all I had to do was hold it in front ...
