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 ...

There are some hotkeys listed for ICS, which hopefully still work with Kitkat: Rotating the screen: (to get that operate we must to have activated “Auto-rotate screen”) Press F12 two times in less than 2 seconds = Rotate 90º to the LEFT. Press F11 two times in less than 2 seconds = Rotate 90º to the RiGHT. Press F10 two times in less than 2 ...

SnooZy Charger 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 to give it the device admin permissions. These permissions are only used to control device locking, as verifiable in its source code. From quickly going through the ...

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. ...

Since Android 5.0 Lollipop, the feature is built-in as one of accessibility options. Open Settings Select Accessibility Below Display section, toggle Color inversion. After toggling it for the first time, the "Invert colors" toggle will be added to the quick settings menu.

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 ...

There is also a shortcut for enabling Background Play, which is tapping and holding the Play button, instead of just tapping it to ...

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 ...

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 have the same issue with my Google Pixel 4a. Fortunately even though overscan is deprecated, setting size still works. The downside is that the screen is centered instead of being aligned to the bottom of the screen. Open a root shell on your phone, then run: wm size # to get your current phone display size wm size 1080x1800 # slightly reduce the display ...

As far as I can see, the only way to archive this behaviour is to switch from stock Android to CyanogenMod - which does have this feature built-in (under "Display & lights" menu in preferences, disable the option "Wake on plug") I'm also searching for a solution on stock Android, but it seems like that's the only way. Too bad, one has ...

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 "...

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.

Dead pixel is a class of manufacturing defects on screens which causes a pixel or sub pixel to remain permanently on or permanently off. The actual cause of dead or stuck pixel varies, and while some may fix itself over time, but many are permanent. Basically, as long as the pixel are stuck on a color that it shouldn't be, it can be considered a dead pixel. ...

Proximity sensors allow the screen to turn off when close to the ear during a call. It should automatically come back when it's uncovered i.e. when it's not close to the ear. That said this app seems to promise that functionality -> Smart Screen On Off
