The situation allowed the most easy if both devices you are using the Chrome browser.

To activate it, simply press the menu button, go to Settings and select "Save traffic." After its activation will schedule, which will show the transmitted traffic and saving as a percentage. Average savings value is 20%, but may vary in either direction depending on the content you are browsing. For example, the browser compresses the image, but saves on surfing sites will not work with encrypted connection. I have this function and pleasant "side effect". Since it is based on the principle that traffic is compressed Google proxy servers, the browser will be able to open the blocked sites provider.
The system of
Almost any modern gadget provides the ability to connect to the VPN, and support USB-host. We will tell you what can be useful these functions.
Initially, VPN technology (Virtual Private Network) was created to ensure that employees of a company could use the resources of the local network of the enterprise from anywhere in the world. Traffic between the client device and the VPN-server is encrypted, making it impossible to intercept it (or rather, it can intercept and decipher here - there). But technology can be useful not only for business users, but also for all owners of mobile devices. If you configure the gadget on your VPN-connection, you can protect yourself against interception of traffic using non-protected access points, as well as from service providers, which can block access to certain sites.
Experienced users know how their own "lift" VPN-server on your home router or leased VPS (virtual private server), but there is an option that is suitable to any - rent a ready VPN-server, which will cost around $ 10 per month. After payment of the services you will receive a login and password, and server address (and possibly some other data) which will only enter into the smartphone settings ( "Other Settings" - VPN). Be sure to check the server type is correct: most often it PPTP, but can meet other options.
In some cases, you can not get the login and password, and the file extension .ovpn, which is used in a free implementation of VPN, called OpenVPN. If you have such a file, called a certificate, you will need to install the official OpenVPN Connect is a free application from Google Play, and import the certificate into it. After that, the VPN-connection will be activated, and no further adjustments are required.
The vast majority of Android-devices has support USB-host, that is, it can be connected to the peripherals - mice, keyboards, gamepads, USB-drives, card readers and other. This will require an inexpensive accessory - USB OTG cable is one of the types: USB 2.0 Type-Amicro-USB 2.0, USB 3.0 Type-Amicro-USB 3.0 or USB Type-AUSB Type-C (there are also other, less common).
Some accessories - most notably, various storage devices - can connect to the gadget without OTG-cable, if equipped with a built-in connector micro-USB and USB Type-C. No drivers or third-party software to connect most devices do not need to: drives will automatically be mounted from the system and will be available via any file manager, and the functionality of a mouse and keyboard can be configured directly from the application "Settings" in Android.
If the cables are not to your liking, but the mouse, keyboard, or gamepad needed, they can be connected and via Bluetooth (of course, if the accessories support this protocol). The difference in the configuration of wired and wireless keyboards are not present. Layouts for them can be selected independently, and multimedia function buttons (if any) will work automatically and does not require any configuration.
sensors and wireless interfaces
Everyone knows that smartphones larded various sensors. And with the help of additional accessories set can be extended by equipping gadget, for example, radiation counter. However, even the built-in sensors can not only adjust the brightness or turn off the screen when presentation to the device to your ear, and wireless modules - not just transfer files.
Practical use of sensors
Typically, sensor readings used by the system and are not available to the user directly. Meanwhile, the information from the sensors can be useful. For example, thanks to the accelerometer, the smartphone is transformed into a simple seismograph, a built-in microphone detects the noise level in decibels. Digital compass gadget responds to a magnetic field that allows you to search in the walls of the wiring or other hidden metal objects. light sensor is well suited for the evaluation of the luminous flux in the suites. Of course, the better the gadget - the more accurate the readings of its sensors. For example, some light sensors champions, unlike inexpensive devices independently measured light flux by three color channels for adjusting the white balance of the screen.
Display information from the sensors are able to many programs, for example, AIDA64, and some, like the Smart Tools, more and represent it in a readable form - it is a paid app, but, in fact, is a set of "tools", each of which can be downloaded from Google Play for free.
If your smartphone is equipped with more sensors and the weather - the thermometer, barometer and hygrometer, you can turn your gadget into a complete weather station, for example, using the "Weather Station" application. It is worth noting that it requires a lot of energy for continuous operation, so it is better to run when a smartphone is connected to the charge.
If you need more accurate data, you can purchase external sensors, for example for household and professional use your smartphone as an endoscope, thermometer, light meter, a device for vehicle diagnostics or measurement of ultraviolet radiation. About this gadget application we wrote in one of our articles.
Payment by the NFC

Some banks offer this capability for a long time, but now the virtual NFC-card issuance process has become so simple that takes no more than 10 minutes and is done entirely from your smartphone using applications, "Wallet". Apart from the issue of additional cards to existing accounts in different banks, it makes it possible to release a completely virtual prepaid card for purchases in stores. Replenish it can be commission-free transfers from other credit cards, or through terminals or mobile lounges. The basic limit of such a card is 15,000 rubles per purchase, and 40,000 on the monthly turnover, but it can be increased by giving your passport information (this process is also carried out through the application and does not require a visit to the bank). In order to pay enough to open the "Wallet", select the card and enter its PIN-code, after which we can only touch the terminal smartphone-enabled PayPass.

It's enough to launch a smartphone camera, bring it on the LED panel and press any of the buttons on it. Since the camera captures the invisible near-infrared range of the eye working IR-LED is visible to the camera as a glow blue or violet light.
