Smartphones of the same model can also cost 100 Euros more depending on whether the internal memory is more or less large, 8, 16 or 32 GB. For the same principle, very small internal memories are often mounted on cheaper Android smartphones, even 4 GB, expandable with microSD cards. However, if you want to use your smartphone or tablet to watch movies or listen to music, without taking up all the internal memory or the SD card where there are also applications, you should use a USB stick, as you would on a computer . When you need it, for example during a train journey, you attach the USB stick to your smartphone or tablet with all the movies inside to choose which one to watch.
This is only possible on Android devices, where, especially when there is no SD card slot, an extra memory such as that of a USB stick becomes very useful for saving large files such as videos, movies and music. The only thing you need is a USB OTG cable, (On The Go), which can be purchased online on stores such as Amazon for 2 Euros or a little more.
What is USB OTG "> On-The-Go" and is the technology of the USB OTG cable, a small cable with a wide "female" end in which to insert a USB device and the other narrower one, of the " male ", to which the phone is connected. The OTG allows the Android smartphone or tablet to recognize, communicate and read the contents of a USB device. An Android device, when connected to a computer, acts as a "slave" and makes its memory available for the computer's operating system.
OTG converts this behavior and makes the device a "master", controlling whatever is connected to it.
You can then, for example, connect a USB keyboard to your smartphone or tablet, or use an external memory for storage, such as a USB stick .
You can then use the USB stick to save video or audio recordings, to save images and photos, to save films and many songs.
You can also connect microSD if you attach a USB adapter for SD memory cards to your mobile phone. The USB stick also becomes a convenient means of transferring data between PC and phone or tablet, without using programs or applications.
As mentioned above, you can buy a USB OTG cable on Amazon or even on Ebay if you prefer. The only problem in using a USB stick on Android as extra memory to add on smartphones and tablets is its portability.
So, if you intend to use a USB memory on Android a lot, it is better to buy a USB OTG pen, which works without cable, with the socket to connect it directly to the smartphone like this USB pen of very small ones and without handle that, a once connected, it almost disappears.
Alternatively, you can choose a mini Micro SD Card Reader adapter with OTG function, for Android smartphones, Samsung Galaxy, Huawei etc.
If you want to connect an external hard drive to your Android device, you need a different Y-shaped OTG cable that also provides power like this.
The USB OTG connection works on almost all Android smartphones from version 3, although not all of them.
If you had the device unlocked with root you can check compatibility with the USB OTG Helper application (requires root permissions), which detects the devices connected via USB OTG cable and mounts them automatically.
To view and manage the files of the USB stick connected with the OTG cable on the Android mobile phone, you must format it with the FAT32 file system and use a file management application on Android as an ES file manager on your smartphone or tablet.
After the cable connection, Android should show a notification.
If you don't see notifications, go to Settings -> Storage to see that the USB stick has been connected and that there is new memory available. This memory should already be mounted, but if not, touch the "Mount" or "Mount" button.
Now the space and the files of the USB flash drive are visible with the file management application through which you can make transfer and copy operations.
Using an app to watch movies and videos on Android such as VLC you can open the files of the USB stick.
