Samsung removed "Stay Awake" from TouchWiz back in the first OTA for the Galaxy S1. Other ROMs like CyanogenMod still have it, and other AOSP based ROMs as well. Be very careful using any kind of "Stay Awake" options with these devices that have the Super AMOLED screens. I used to use it when developing and testing the apps. I now have a "burn" in the ...

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. ...

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.

There just was a Blog on Land of Droid covering this issue. The author summed up a few conditions under which this "flicker" occurs: back-light is dimmed under 30% a weak WiFi signal the device is accessing the net According to that report, these 3 things are "AND-connected" (i.e. the flicker occurs when all of the 3 conditions are met). He's also hoping ...

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 ...

At least in vanilla ICS it's in Settings -> Developer options -> Stay awake, correct me if it's not there in GSIII. If it's not there, you can try a couple of apps that can do this, at least on older Galaxy series phones. StayAwake Stay Awake Widget

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. ...

The 1280x800 pixels count for the whole display, including the black bar for the buttons. Google decided to stay flexible by moving physical buttons to the touch screen permanently.

You can always use some mathematics to obtain screen size: X = sqrt ( Z^2 / (1 + (VR/HR)^2) ) where: sqrt = Square Root √‾‾‾ X = screen width Z = diagonal screen size (7" for Nexus 7) VR = vertical resolution HR = horizontal resolution which for Nexus 7, we have: Z = 7" VR = 1280 HR = 800 so: X = sqrt ( 49 / 3.56) X = 3.71 ...

As life of LCD screen is measured in hours of its usage, keeping screen turned on does consume some of its life hours. But, average life of LCD screens range from 30,000 hours to 60,000 hours, so I don't think it would a matter to you.

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 ...

Sounds like this is one of two things to me. Either a faulty screen / hardware. OR depending on the severity of this flicker it may be that the device has a light sensor that is trying to change the screen brightness based on the ambient light surrounding the device. You could rule out the second option by going to your screen brightness in the settings ...

Contacts on SIM-Card are very limited -- so they e.g. can only store one phone number. Your phones / Google contacts, however, use a much enriched format, where you can store additional information like multiple phone numbers and even pictures. Naturally, both formats are not 100 compatible. When exporting your contacts to SIM, information must be cut down ...

I've managed to deal with this problem by performing a "soft reset". Hold down the power button for around 30 seconds, the device should start a soft reset (i.e. you don't lose any data/settings etc.) and reboot. -- Why it blocked and prevented me from performing a screen unlock remains to be explained.

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 ...
