To understand why Nexus 7 can show more content than the Galaxy Nexus, I'll first explain two concepts: screen density and density-independent-pixel. But before we go into technical details, it may be worth to clarify the design goals of using density-independent-pixels. The goal is to define a UI that is similar in dimension across devices, regardless of ...

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 ...

This depends on the screen technology. For instance, (it was said that) Android 2.3 Gingerbread has dark theme since Google's latest flagship device Nexus S uses (Super) AMOLED display which consumes less energy when displaying dark color since AMOLED produces its own light and darker color emits less photons. Contrasts with LCD display which uses a ...

Hey, I just ran a load of test to figure this out. They are vaguely scientific tests! I figured out that I was saving 20% battery by switching to dark wallpaper and dark themed apps. Have a look through my write up, you should be able to work out the saving on your phone: http://blog.stevemould.com/phone-battery-save-black-wallpaper/

It depends, some Android devices have an advanced setting WiFi Sleep Policy under Settings -> Wireless -> Wi-Fi Settings -> [Menu Button] Advanced -> Wi-Fi Sleep Policy But I am not sure if this is a vanilla Android feature or an manufacturer modification. At least the Galaxy S series has this setting. Data networks are usually fully active. ...

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 ...

I use Quick Settings and there's an option to toggle auto-rotate. I have it so the shortcut to Quick Settings lives in my Notification bar so to toggle it requires a swipe, two taps and the back button to toggle it and get back to the app I was in. If you wanted to reduce this down to tap home, toggle, tap return if you use QuickDesk which lets you put ...

If you don't mind paying a few bucks, I highly recommend Tasker. This automation utility allows you to set up many built-in (and some 3rd-party app) Android actions based on various parameters, including time of day. In Tasker you will need to create 2 separate profiles, and to each add 2 actions. 1st action will be identical in both profiles - disabling ...

I have checked on my two Ice Cream Sandwich Devices (Stock Xoom and Droid 3 running CM9 Beta). I have, under Settings > Developer Options a Stay Awake option. Which keeps your device awake when charging. This will work if your device charges over USB (my Xoom does not, for instance). However, should this option not be there, we can turn to apps for ...

No, what matters for clarity is acuity, or the "number of pixels versus screen size versus viewing distance". A 800x480 image shown on a 100" monitor seen 30 cm viewing distance would look awfully pixelated, while 480x320 screen on a 2" monitor seen at the same viewing distance would look very sharp. LG Optimus S has a 480x320 pixels on a 3.2 inch screen ...

That's because the pixels per inch (PPI) is different between them. The higher the PPI, the higher the quality but at a cost of (relative) smaller screen size. So the Nexus 7 has 216 pixels per inch while the Galaxy Nexus has 316 pixels per inch. The resolution isn't everything, you also have to consider the density of the pixels. High PPI values have the ...

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

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. Benefits: No capacitive buttons needed (cheaper?) Better user experience: Rotating 90,180,270 degrees rotates also the virtual buttons Less frame space (the button's space ...

I want to run a screen saver when phone is in sleep mode. When the phone is in sleep mode, the screen is off. When we stay idle some time a black screen comes. This is built into Android. At that time I want to display some images as screen saver. I repeat, when the phone is in sleep mode, the screen is off. Is this possible? You ...

ICS (Android 4.0) includes the capability for "Screen Candy" that is special screens or animations that only present themselves when the phone is idle and plugged in or docked. By default, this is a hidden (disabled in most stock roms, I'd wager) feature called "Android Dreams" but enabled in most custom roms (such as AOKP or Codename Android). ...

Unfortunately you can't change the number of screens and still use the HTC Sense UI. At least not in any of the versions I've seen. You can uninstall it or turn it off, but then you won't have free access to all of the HTC widgets, if you like those. If you really want the performance kick you'll get from less screens in total, and therefore using less ...

Not sure what phone you've got but most of the higher end Android phones have light sensors, and you can set the screen to adjust its brightness automatically depending on the ambient light at the time. If you've got the Power Bar widget on your home screen (its one of the built-in Android widgets since Donut) just tap the far-right brightness icon until it ...

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 = ...

The screen is glass. Since the release people were having issues with the screen due to the glass sometimes cracking when in tight pockets... this would usually not occur with plastic since plastic is a little bit more flexible. HTC says broken glass means Nexus One not for pocket Design: Solid, but Not Groundbreaking

I do not believe Android 2.1 allows this. I've read that the latest release Android 2.3 (Gingerbread) will have this feature. Sorry I couldn't find the post that mentioned it but here is the API link.

This is something of an oversimplification, but the simple answer is: you can't. What makes this an oversimplification? Well, it's because it depends on how a given app is implemented. Android applications are based around the concept of an Activity, which is described in the development documentation as: An activity is a single, focused thing that the ...

The S2 has Samsung's toughened Gorilla Glass screen, see the videos in this answer to a previous question for attempts to scratch the Gorilla Glass on an original Galaxy S: Looking for a robust Android smartphone I can say that I've had an original Galaxy S for over a year now, and regularly keep it in a trouser pocket with my house keys, have dropped it a ...

It's likely the matrix which you are seeing. http://en.wikipedia.org/wiki/PenTile_matrix_family The Galaxy Nexus uses the RGBG matrix just like previous galaxy, however it's much higher resolution than many other pentile displays. Here's a magnification of another, similar screen from a different samsung phone. ...

The Samsung Galaxy S II does not have this feature, and never has, because of its AMOLED screen. They burn (like CRTs) if they have the same picture on the screen for too long. For some reason apps can still lock the screen on, but you can't do it from settings. (My Samsung Galaxy S II has burn in from the notification bar.) You can use StayAwake, just ...

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.

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.

In general, the less widgets you use on your home screens, the better performance your phone is going to have (less processing for widgets). If you want to reduce the number of homescreens, then I suggest switching to another home launcher such as LauncherPro which will let you change how many homescreens you have. LauncherPro has some similar widgets to ...
