"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. ...

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, ...

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 ...

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 ...

have the same issues as the first bloggers that posted. I have the Nexus 4 16Gb and in February 2014, I cracked the screen and changed the digitizer. In the process I tore the lithium polymer bag for the battery and subsequently the phone started to have a sweet smell. After 5 days the phone started acting up with these ghost images which was typing the ...

I have had this issue before when I rooted my galaxy ace it was extremely random and I fixed it by flashing an old stock rom and then using Kies to upgrade to the latest. If this doesn't work it would suggest that your digitizer has gone, or is in the process of going. If you have time remaining on your warranty, and have returned it to stock, you should ...

I recommend getting Air Swiper with which you can turn on your device just by swiping above the sensor (which is located with your front camera), and you can also turn it off by swiping as well.

Try Settings->Developer Options->Show touchscreen touches. Unfortunately, HTC likes to move these settings around between versions so I don't know if it will work for you. Replacing the digitizer is possible on many HTCs, I did it on my EVO 3D. But that's probably what has failed. Condensation will confuse it and make it stop functioning .

If I were you I would try to get control over the device using ADB. From there you can get your files back and root the device if you want. Also as Izzy suggested in the comments, there are several applications for a device with a cracked or unusable screen. Android is Linux based, so Android can do almost anything a Linux based server can do. You can find a ...

My opinion is the screen might be grounded with some metallic or conductive object inside the phone. Probably a loosened part due to use. You can try to wave a strong magnet (like neodymium) at the back of the phone. Data shouldn't be affected anyway because flash chips are resistant to magnetism. But its still much better if you can get it repaired thru ...

As you asked for a calibration tool: The Playstore seems to have some suitable candidates, e.g. Touch sensitivity calibration. But while this might be helpful, the permissions look quite suspect: The only job of the app is screen calibration, but it requests permissions such as accessing your contacts, call phone numbers, read and send SMS/MMS, and more -- ...

Today I was super excited to see That my screen is fully functional. I will continue to charge it like this for few days to see what happens. No problems for about 9 hours so far. ยจ update: 4 days have been ...

some basic general troubleshooting steps that you can try to get a touchscreen working again. Step 1 More RAM consumption Turn the device off, wait a few seconds, and then turn it back on again. This process will clear out any software errors that are causing the touchscreen to malfunction. If the touchscreen still doesn't work, remove the device's ...
