The Developer Options menu in Android is a hidden menu with a variety of advanced options. These options are intended for developers, but many of them will be interesting to geeks.You’ll have to perform a secret handshake to enable the Developer Options menu in the Settings screen, as it’s hidden from Android users by default. Follow the simple steps to quickly enable Developer Options.
Enable USB Debugging
“USB debugging” sounds like an option only an Android developer would need, but it’s probably the most widely used hidden option in Android. USB debugging allows appliions on your computer to interface with your Android phone over the USB connection.This is required for a variety of advanced tricks, includingrooting an Android phone, it,installing a custom ROM, or evenusing a desktop program that captures screenshots of your Android device’s screen. You can alsouse ADB commandsto push and pull files between your device and your computer orcrte and restore complete local backups of your Android device without rooting.USB debugging can be a security concern, as it gives computers you plug your device into access to your phone. You could plug your device into amalicious USB charging port, which would try to compromise you. That’s why Android forces you to agree to a prompt every time you plug your device into a new computer with USB debugging enabled.
Disable or Speed Up AnimationsWhen you move between apps and screens in Android, you’re spending some of that time looking at animations and waiting for them to go away. You candisable these animationsentirely by changing the Window animation scale, Transition animation scale, and Animator duration scale options here. If you like animations but just wish they were faster, you can speed them up.On a fast phone or tablet, this can make switching between apps nrly instant. If you thought your Android phone was speedy before, just try disabling animations and you’ll be surprised how much faster it can seemForce-Enable FXAA For OpenGL GamesIf you have a high-end phone or tablet with grt graphics performance and you play 3D games on it, there’s a way to make those games look even better. Just go to the Developer Options screen and enable the Force 4x MSAA option.This will force Android to use 4x multisample anti-aliasing in OpenGL ES 2.0 games and other apps. This requires more graphics power and will probably drain your battery a bit faster, but it will improve quality in some games. This is a bit like force-enabling antialiasing using the NVIDIA Control Panel on a gaming PC.See How Bad Task Killers AreWe’ve written before about how task killers are worse than useless on Android. If you use a task killer, you’re just slowing down your system by throwing out cached data and forcing Android to load apps from system storage whenever you open them again.Don’t believe us? Enable the Don’t keep activities option on the Developer options screen and Android will force-close every app you use as soon as you exit it. Enable this app and use your phone normally for a few minutes — you’ll see just how harmful throwing out all that cached data is and how much it will slow down your phone.Don’t actually use this optionunless you want to see how bad it is! It will make your phone perform much more slowly — there’s a rson Google has hidden these options away from average users who might accidentally change them.Fake Your GPS LoionThe Allow mock loions option allows you to set fake GPS loions, tricking Android into thinking you’re at a loion where you actually aren’t. Use this option along with an app likeFake GPS loionand you can trick your Android device and the apps running on it into thinking you’re at loions where you actually aren’t.How would this be useful? Well, you could fake a GPS check-in at a loion without actually going there or confuse your friends in a loion-tracking app by seemingly teleporting around the world.Stay Awake While ChargingYou can useAndroid’s Daydrm Modeto display certain apps while charging your device. If you want to force Android to display a standard Android app that hasn’t been designed for Daydrm Mode, you can enable the Stay awake option here. Android will keep your device’s screen on while charging and won’t turn it off.It’s like Daydrm Mode, but can support any app and allows users to interact with them.Show Always-On-Top CPU UsageYou can view CPU usage data by toggling the Show CPU usage option to On. This information will appr on top of whatever app you’re using. If you’re a Linux user, the three s on top probably look familiar — they represent thesystem load average. From left to right, the s represent your system load over the last one, five, and fifteen minutes.This isn’t the kind of thing you’d want enabled most of the time, but it can save you from having to installthird-party floating CPU appsif you want to see CPU usage information forsome rson.Most of the other options here will only be useful to developers debugging their Android apps. You shouldn’t start changing options you don’t understand.If you want to undo any of these changes, you can quickly erase all your custom options by sliding the switch at the top of the screen to Off.Set a Desktop Backup If you use the above ADB trick to crte local backups of your Android device over USB, you can protect them with a with the Set a desktop backup option here. This encrypts your backups to secure them, so you won’t be able to access them if you forget the .
Pointer LoionThis is a fully developer mode option ,in these option you can see where you touch screen and he show the exact loion of your touch.
Show TouchesThis is very cool option you can see where you touch the screen and he shows the white dot.
