Phones with otg android function. Guide to connecting a USB flash drive to an Android and iOS smartphone. Does your phone support USB OTG?

And about that. These articles mentioned On-The-Go technology in passing. I think that we need to dwell on this topic and consider it in more detail, what's happenedUSBOTG And what's happened, so that there is no longer any ambiguity when you see this abbreviation.

USB On-The-Go (or OTG) technology

USB On-The-Go Technology is an extension of the USB 2.0 specification, which is used to easily connect peripheral devices directly to each other without the use of a laptop or computer. For example, using this technology, you can connect a digital camera (or smartphone) to a printer and print required document, be it a photo or a text file.

In general, On-The-Go technology arose precisely because of the need to use common peripheral devices without the help of a computer, which, by the way, may often not be at hand.

The USB OTG standard uses a master-slave architecture. That is, the devices themselves determine which of them will be the master device and which will be the slave. Of course, this is not a literal translation. Verbatim master translates as teacher, master, owner, lord and so on. A slave, in turn, is translated as slave, subordinate... Make your smartphone the master of the flash drive.

Using USB OTG

Now OTG technology is used in almost all modern devices, which makes it possible to connect devices such as a USB drive (either a flash drive or an external hard drive), a keyboard, a mouse, a joystick, an external webcam, a printer, or a digital camera to your smartphone or tablet. and so on.

USB OTG cable (and hub)

OTG cable

To connect these devices, you can use a standard one, if your device has one. And if it is not there, but there is only a micro USB connector, then you must use USB. If desired, you can connect several devices at once. For this you will need USBOTG hub (USBOTGHUB). There are also an OTG cable and an OTG hub with additional power in case the voltage of your device is not enough to connect some energy-consuming devices (for example, an external hard drive).

Conclusion:

Included with numerous smartphones or tablets based on Android you can find an accessory called an OTG cable, but many users cannot figure out what it is and how to use an OTG cable, as well as what additional features it gives your device. In fact, it can be extremely useful, especially if you want to use your device in combination with additional equipment. It is necessary to understand why this adapter is useful and how it can be used.

Purpose of the OTG adapter

So, what is an OTG USB cable? It is a special cable (adapter), on one end of which there is a full-type USB port, and on the other - a mini or micro USB. A full-fledged USB port is used to connect to peripheral devices, for example, a computer mouse, keyboard, flash drive and other devices. The second end is connected to a smartphone or tablet running Android OS. After connecting to all devices, a message appears on the display of the Android device stating that the peripheral equipment is ready for use (provided that you have connected everything correctly, and the tablet or smartphone supports working with the adapter at the software and hardware level). All devices connected to a mobile gadget receive power from it, except for those cases when they are connected directly to the electrical network.

If you have special devices, tools and skills, you can make an OTG cable with your own hands. The essence of this process is to close the last two contacts, which are contained inside the connector.

What can you connect via OTG USB cable?

How to use OTG on a tablet or smartphone - there are quite a lot of possibilities for its operation, it is necessary to note the most common among them:

Connection hard drive or external storage (flash).
Connecting peripheral devices such as a mouse or keyboard.
Connecting to a mobile printer device.
Fast file transfer.
Demonstration of media files from a smartphone or tablet on a large screen.

When you connect an external drive for storing data to the gadget, the message “Preparing a USB drive” appears on the device display. After the device is ready for use, you can view all the files stored on the drive or disk using the usual file manager. Remember to use the safe eject feature before disconnecting the drive. It provides an opportunity to avoid damage to files stored on the drive and other troubles (the same function is available on a desktop PC or laptop).

Using the mouse on an Android tablet is very simple: one click selects objects, two clicks launch programs and applications. A computer mouse greatly simplifies the control of a mobile gadget. If we talk about the keyboard, it provides the ability to quickly type text, thereby turning the tablet device into a kind of netbook. Thanks to the OTG cable, you don't need to search alternative ways connecting all this peripheral equipment. The same goes for webcams and other devices. Before connecting a printer to your device, be prepared for the fact that OTG USB cable technology is only available for the newest and most common equipment. In addition to the cable, you will need to download and install from Google Play a special application that will help you connect the printer and also simplify its operation. If all steps are completed correctly, you will be able to print photos or text documents directly from your phone.

To appreciate the fast file transfer using an adapter, imagine that you need to transfer data from a tablet to a flash drive (an ordinary USB flash drive). The traditional method involves transferring files from the gadget to the computer, and then from the computer to a flash drive. Thanks to OTG, you can quickly transfer from Android directly to a flash drive, it only takes a few minutes.

Watching videos, films, photos is much more convenient and enjoyable on a big screen, for example, a TV. If you have a modern TV model at your disposal, then you can organize a demonstration of media files from a tablet or smartphone on the TV screen, and connecting an OTG cable will help you with this. To do this, just connect these two devices using a cable. TV in in this case will play the role of a projector.

Which devices support OTG cable?

It is believed that any equipment that is equipped with a USB port can work with an OTG cable, but in reality the situation is a little more complicated. The easiest way is to connect an ordinary flash drive with a capacity of up to 32 GB to your Android device. It is more difficult to use a hard drive that will receive power from the device, since it lacks power. If the drive is powered from the mains, no problems will arise.

Also, difficulties do not arise when connecting the following devices:

mice;
keyboards;
game joystick;
steering wheel;
cameras;
computer speakers
card reader.

Moreover, you can connect several peripheral devices to a smartphone or tablet at the same time, but to do this you will have to acquire a USB hub (splitter) equipped with several ports. The more equipment connected, the faster the battery drains.

Smartphones and tablets that support OTG, as a rule, belong to the mid-price segment or flagship devices. Many developers do not provide this feature to users to save on installing the appropriate software or to reduce battery consumption.

Conclusion

Now you know how to use a USB OTG cable, what it is intended for, and what difficulties may arise when trying to connect a particular device to your Android smartphone/tablet. This adapter can be a truly useful assistant in work, learning and entertainment. Even if OTG is not included in the package, but the gadget supports it, you can purchase a cable at any store.

Introduction

Hello! I decided to write an article so as not to answer the same questions. I was thinking about where to post it so everyone could read it, and I remembered Helpix. It's been so long since I've been here! Several years have passed since the last review. I went to the site and remembered my feelings three years ago. For this alone already Thank you! Although I still sometimes receive comments on old posts and I come in to respond. Well, okay, back to the topic. In general, it turned out that I was often asked about USB OTG. It seemed to me that all smartphone and tablet users knew about this. But after being asked about 10 times in a few days, I thought that I needed to do something. At first I sent everyone to Google, but people are lazy now and want to hear about it from me. That's how I ended up here again.

What is USB OTG?

Let's start with what USB OTG is. Since I am also lazy and too lazy to type a lot, I will quote, which I liked because it is easy to understand.

"USB OTG (from English On-The-Go) is a USB function that is designed to easily connect USB devices to each other without the need for a computer. In practice, this means that two devices that support this function can be connected to each other to a friend directly. For example, you have a camera and you want to print photos. You don’t have to connect it to a computer, you can connect it directly to a printer and print photos. However, in most cases everything is much simpler and OTG is usually used to connect a flash drive. to a smartphone or tablet using USB - in this case, you can read data directly from a flash card. For example, you can run a movie on the device screen, which, in turn, was downloaded to the memory card."

How does this work?

An OTG cable is used for connection. There are two cables in the photo below. Both USB OTG. The only difference is that one was purchased from DNS for 390 rubles. and is called "Ginzzu". The second one was purchased on AliExpress. No Name for 18 RUR There is a film on the second cable for transportation, so as not to be scratched! For 18 rubles! Same quality...

This is what the connected flash drive looks like:

You can also connect mice, keyboards, hard drives, etc. Hard drives require additional power from the network. For example, you can also charge your smartphone from your tablet.

After the popularization of USB OTG, various gadgets began to appear. For example, a flash drive with an additional microUSB connector, OTG hubs, a fan for smartphones, etc. As an example, I ordered a couple of adapters on AliExpress.

I love useful multifunctional things. For example, here's an adapter. A microSD flash drive is inserted into it and can be used as a regular USB and at the same time OTG flash drive.

Such an adapter costs about 50 rubles. When connected, glows blue.

By the way, thanks to him, I realized that I have OTG on my tablet. My tablet is Prestigio Multipad Ranger 8.0 4G. It didn't have OTG support in its feature description. When checking via cable, the flash drives were also not connected. But this confused me, since almost all tablets from this company support OTG and the cable comes with them. I remembered the first version of the Yoga Tablet, which had a GSM function in addition to WCDMA, but due to the firmware it was not possible to use cellular communications. In general, when the adapter arrived and I connected it to the tablet, it lit up, but the flash drive was not detected. I started studying the topic and found out that since there is power in the USB, it will work. I installed various file managers to work with OTG. As a result, I installed Nexus USB OTG File Manager, and the flash drive was detected. The strangest thing is that after that the ES conductor began to see her.

Now the file manager has been renamed and made
