This appears to be called EdgeEffect and is used as a visual indicator when the user over-scrolls. See relevant images on Google Images here. A book commenting on the glow effect produces. A question on Stack Overflow.

Capacitive and resistive touchscreen technologies Today's multi-touch screens are capacitive, unlike the resistive touchscreens from a decade ago. They work a bit like the way you can feel a static charge with the hair on your skin. The screen has a charge inside it, and when your finger comes near it, the capacitance of your finger attracts this charge. ...

Notes: My solution is tested on Stock Android 4.4.2 and Stock CyanogenOS 12 (5.0) of OnePlus One, and should work for Android 4.3 and above (based on this answer). I've mentioned wherever root access is required. This answer has been taken from my answer on a bit different question here. I have used the following comment as the ground to work on: The ...

SnooZy Charger (also in the Play Store) takes care of this. The free app (as in beer and speech) that lets you manage behavior during charger connection and disconnection. It requires no permissions, but does require you giving it device admin permissions. These permissions are only used for to control device locking, as verifiable in its source-code. From ...

As suggested already, this graphical "shadow" effect is Edge Glow colour, and its part of the material design by Google. After the introduction of material design by Google many new UI elements have been introduced. Material design is based on the interaction and movement of colours and objects in real world rather than synthetic unnatural phenomenon. ...

It seems like others have had this problem as well: http://www.reddit.com/r/GalaxyNexus/comments/19y0a9/galaxy_nexus_screen_turn_on_durring_lock_screen/ http://productforums.google.com/forum/#!topic/mobile/PA5JZH-Oj4o http://code.google.com/p/android/issues/detail?id=39625 It is a bug in Android 4.2, specifically with the Samsung Galaxy Nexus.

there is a setting in developer options on your phone that allows you to keep your display awake whilst charging it. It is enabled by going to settings, then scrolling all the way down to about. From there scroll all the way down to build number and tap it 7 times to enable developer mode. Next, click the back button then click on Developer options. Click ...

There are two ways of doing this, depending on if you have root or not on your device. If you use root If you have rooted, run: su input keyevent 26 In any good terminal emulator. If you have not rooted If you haven't rooted, either root, or: Install ADB (Instructions vary between windows, Mac and Linux) Enable "USB Debugging in settings > developer ...

If you know for sure your phone can be powered on, then there might just be another doable (albeit technical) way. I've extracted photos and contacts from another S4 of my classmate a while ago using this. I'll describe it and let you decide whether you can handle it. While in the blind, get to Download Mode by using the key combo. Load a custom recovery ...

My answer for you is twofold; there are innate downsides to off-brand devices but - most importantly - your use case (development and application purposes) might make off-brand Android phones a poor choice. This is from my experience with the phones (I have a lot, having lived in Asia for years, and seeing a lot here in the States) First, the general ...

The short answer is NO. Unless you try to go over default brightness (which could potentially burn the LED), your screen leds are desgined for changing brightness and colors. Leds work differently than most lightbulbs and flicker has much smaller effect on them. Longer version of explanation First of all, leds do not "flicker" the way fluorescent light ...

In gingerbread 2.3.6, you can turn it off in Call Settings>Additional Settings then uncheck the "Turn on proximity Sensor". Here is a screenshot:

Izzy opined it correctly here that the only sensible place for having factory home screen layout is the launcher's APK itself. Since I don't own a Lenovo device let alone your specific model I used my MTK device running stock 4.2.1 as the testing ground. It has stock launcher (com.android.launcher). About that thing called factory home screen layout -- ...

For me Tasker did the job, but you need an additional Tasker plug in for this, called AutoTools. On my bq android device root wasn't needed to do the job. I set up a profile to invert the screen when I open specific apps like my newspaper reader.

I don't know any way to do it by system tools. However, I know couple of apps, which will let you complete this task. You need root access. Here is what I have: Ultimate Rotation Control and GMD GestureControl Lite. GestureControl lets you tight almost anything to any gesture. And URC has an ability to share switches of orientations of screen as "...

Apparently, "This is not a user-configurable option right now". I'm not sure if that's a general Android problem, or a specific cyanogenmod one. Totally clueless about why, of course.

There's an easy way to check if the tablet has a faulty touchscreen. Go into Google Play and install a painting app. There are many free painting apps to choose from: just pick a simple one. Run the app and try to paint the whole screen. If the painting doesn't follow your finger, or any parts of the screen can't be painted, you can see the screen is faulty, ...

Looks like a damaged LCD that's slowly "leaking out." Overheating could definitely be the culprit, as could the drop. Although damage from the drop is usually accompanied with a visible crack. Most likely it was the combination of the two. The fact that the phone booted up and is (sort-of) functional leads me to believe that replacing the LCD assembly ...

I am answering my own question, because i somehow solved it. I downloaded the Battery Doctor app (the one featured by Clean Master) and created a scheduled profile for night that has timeout set to 5. Also enabled 'charging screensaver'. It's ok now. Battery doctor takes over the TouchWiz uselsss popups and notifications, and forces it to stand by after 5 ...

I had the same problem and today I did find what was causing my problem. It just started yesterday, 2 weeks after I got the phone. And the ONLY thing that was different is that I started using a generic AC charger that arrived yesterday. When I suspected it was the charger this morning, I switched back to the white Samsung charger that came with the phone -...

I found the easiest way to do this was with the application Color Wallpaper. All the possible colors selectable from a menu, and i haven't changed the color in months. You can set it and forget it. Even uninstall after setting, if that is your wish. Disclaimer: I am not the developer of this application, just a satified user - for years.
