Looking at your screenshot, I think you are using screen filtering apps like Twilight, f.lux, CF.lumen and bluelight filter. Try to force stop/uninstall/disable the screen filtering app and it will work again. If you are not using any filtering app, try looking for your installed apps that have overlay capability, apps that can show their contents over ...

Background Only Android devices that are licensed by the Open Handset Alliance contain the so called Google Apps. Usually people associate apps like Google Maps, Google Play Store, etc. with Android, but because of the open-source nature of Android, manufactures can sell Android devices without Google Apps and therefore avoid to pay the license fee. Custom ...

In fact, it is not necessary to install the entire SDK if one does not want to use it for development. To be able to run basic ADB commands in the context needed by an average user, a rudimentary installation is completely sufficient. I will try to explain how to do this, and hopefully cover the most used computer systems. Requirements First, you will need ...

Root access (typically) requires several components that work in concert with one another. A somewhat simplified view of what you need is: A native su binary. This can be invoked from the command line or from applications. It is what actually performs the act of switching users, and grants a process root permission. A "gatekeeper" application, that ...

You don't need an external tool for this. On the versions of the Play Store with the new "simplified" permissions dialog, you can still find a full list of permissions from the app's store page (the screen with the icon at the top, description, screenshots, &c.). Scroll down to the bottom of the page. Under "Additional Information" you'll see "...

In his answer, Dan already pointed to my list of apps by real-life topics, which offers some extras as well. Currently, it only covers a small subset of what's available on Google Play, though (for some numbers: ~10,000 apps = ~1% of Google Play, including roughly 5% of the apps available in Aptoides (curated) main repository, and a third of the apps ...

If you have a fastboot-enabled bootloader version (such as the old 0.76.0000 engineering HBOOT in the EVO's case) you can use that to flash it from a PC via USB. Reboot into your bootloader, then select the "Fastboot" option from the boot menu (if it has one, it may start up fastboot automatically). Once it's ready, go to your PC's shell and execute: ...

If you have a 4.x device, the automatic backup/restore found under Settings -> Backup & reset -> Back up my data and Automatic restore options work fine. It uses Google's own servers to save a list of apps installed on your phone. After a factory reset once you sign in with the same Google account, it gives you an option to restore those apps. ...

.apk files are downloaded and stored in subfolders under a location on your device called /data. By default, you do not have permissions to read from that location. In order to read/write in that location, you will need to root your device.

for 99% of devices, you have to have a custom recovery image installed on the device in order to install CyanogenMod. And usually, to do that you have to have the device rooted. So you have to have a rooted device before you can install cyanogenmod. CyanogenMod comes rooted and yes, it is an android release. Rooting a device, while it will void your ...

At least on my phone, it seems you need way more available space thanthe size of the app you are actually trying to upgrade. In my case it seems I needed to have at least ~13MB free space to upgrade anything at all (even for 500KB apps). Some tips to free space: Go to Settings, Applications, Manage Applications, click "Move to SD card" on the ones that ...

Unfortunately Android doesn't offer this functionality out of the box. There are several 3rd-party apps on the Market that can help though. I personally use App Protector Pro on my son's tablet. This app allows you to set a PIN and then set up a "block list" of any installed apps, including system ones. Among other apps, I added Settings and Package ...

According to the list of status codes at Wikipedia, a 504 error means the following: 504 Gateway Timeout The server was acting as a gateway or proxy and did not receive a timely response from the upstream server. In other words: the culprit should neither be (on) your device, nor (at) Google Play -- but in between. A thread on the Nook forum describes ...

.exe Files are Windows binaries (i.e. executable files/applications/programms) that can not be run natively on a Android system. I am sure the Play Store (or the alternatives of the Play Store) will have an equivalent app to the .exe file you are trying to run.

You can grab the latest .apk on a PC from Mozilla's FTP server and sideload it, as noted on Mozilla's wiki. If you're unsure of how to sideload an app, you can find a variety of methods in How can I install an app given only its APK file? (some require internet connectivity, many do not).

First, disable the primary source of installation. On most devices, it is the Google Play Store but your device might have been shipped with a non-Google market app as well. So go to Settings → Apps → (three-dots line → Show System) or (All Apps) → your market app → Disable. Second, disable the Package Installer system app. This ...

If you have a fastboot-enabled bootloader then it should be pretty simple. Just put the system.img file somewhere on your PC, connect your device via a USB cable, reboot into your bootloader's fastboot mode and then: fastboot flash system /path/to/system.img If you don't have fastboot then you'll have to jump through some more hoops. One option would be to ...

No. Users are not allowed to write to the /system folder/partition. Any sort of exploit or method that would allow this partition to be writable is equivalent to root access on the device. Some other examples besides root are: "Rooted recovery" which is a recovery partition that has more features than the standard Android recovery; an "Engineering" (HTC) ...

For the following procedure you'll need adb installed on your computer (if you're not already have that, see: Is there a minimal installation of ADB?). Alternatively, a terminal emulator app should do as well. Android apps are managed by the "Package manager", which has a command-line interface called pm. So here's what you can do with it for your case: # ...

It seems error 923 is related to the whole process of downloading, cache, storage, installation, etc. People get it most often in Google Play, but sometimes also outside of that. Most suggestions how to fix this come down to: Settings > Apps > Running > stop all (Google related) running services Settings > Apps > All > Google Play Store > ...

On desktops and laptops, drivers are a necessary evil. Hardware is often user-serviceable and prone to changes, and there is a huge variety of possible combinations. On phones and tablets, this isn't quite so. You can't really change the hardware easily. It's entirely safe to disallow driver installation since you don't really need it. It is a lot easier to ...

The only log I remember, that contains installation success/failure info is the one that can be accessed via ADB (android debug bridge). The command is: adb logcat But you might not have the Android debugging tools installed, so an easy way of looking at the logcat is to install aLogcat from market. Because that log is a memory buffer (I learned it form ...

NOTE: LBE Privacy Guard is no longer maintained and only available for Android versions below 4.2. Warning: if you are on Jelly Bean (Android 4.1+), be sure to check whether LBE has been updated for Jelley Bean yet. At the moment (July 27 2012) it is still incompatible, and it will cause your device to boot loop on Jelly Bean. That means you may have to ...
