I think you've got to differentiate between "software-layers" and "hardware-layers" in the first place. If you put a "display foil" on top of the screen, that will certainly not reduce battery consumption (though it "dims" your display). But if it's a software layer reducing brightness, that's something completely different: How should that be achieved other ...

Even if that is true, that would not apply to all screens such as an (AM)OLED screen that doesn't use a backlight. From Wikipedia article on amoled: The amount of power the display consumes varies significantly depending on the colour and brightness shown.

The refund button on the Play store is only available for 2 hours (although Google's support pages say 15 minutes). From your question it sounds like you may be the developer of the app, in which case you can manually refund the purchase regardless of when the app was purchased via your Google Wallet merchant account. I don't think this actually reverses ...

I think you may be confused as to how your phone works. The phone has a battery which needs to be charged. When you use an app it uses up some of the charge in the battery (by using processor, phone signal, wifi, and the screen). Just like you don't need to charge each phone number that you call separately (you just charge the phone and then make phone ...

The new way Playstore lists permissions on install and update make it difficult at best to see what an app requests permissions for. While before that change, one saw at least those (but still didn't know what the app would do with them), now even that possibility is gone for good – except if you want to go to the website all the time to check manually. The ...

Multiling Keyboard, supports multiple languages (including Vietnamese), highly customizable, the only keyboard I know of that doesn't require Internet permission (so the ...

To control the breadth of activities this app declares for itself, it probably has set itself up as a Device Administrator, to control the ability to run many aspects of your device automatically.

The App your looking for is kWS. It will serve any html file you have on your phone to port 8080 (or other unused port), and it doesn't require a root. If you want to run a custom server (i.e. with sockets), you'd need to develop your own app with sockets, although you'll need to know Java.

No. Even humans, who are much better at vision and understanding pictures than computers are, can't determine accurate dimensions just by looking at a photo. The closest you can get is apps like in Is there any app that measures the distance using the camera?, but they can only answer simple questions using trigonometry: if you know how far an object is ...

Yes, those apps are stock apps in the German-localized ROMs for the Galaxy S3 (the i9300 version). Likely they were there in the original ROM but you uninstalled them and later forgot about it. It's fine to just uninstall them. The seventh and eight digits of the IMEI don't have any meaning in current phones. Before 2004, they indicated the country where ...

It is as simple as running adb install -s someapp.apk. However, the app should be ready to run from external storage. adb resides in the path to ADT/sdk/platform-tools directory. Related question: Move to SD Card doesn't move everything

What are you putting in for the package name that it doesn't like? Beginner mode vs non-beginner mode shouldn't matter. Package name has to have at least one . in it to be valid. Usually you can just use your email backwards along with a unique name for the app. Say your email is someone@gmail.com and you're trying to export an app you want to call myapp. ...

Adobe Reader can follow hyperlinks in PDF documents. The problem (currently, 2014-09-17) is that the default application associated with PDF documents is Quickoffice, and Quickoffice doesn't have this implemented. Installing Adobe Reader allows you to choose (and optionally remember your choice) what app to use.
