Exploring the causes
Using an ordinary flash drive, as a rule, does not cause any problems. The smartphone always finds the device and works properly. But things are different with portable hard drives. Even a perfectly serviceable device can fail. There are a few reasons for this:
The phone does not support the OTG option at all – modern models of devices support this technology almost 100% of the time. However, before buying a cord, it is recommended to read the documentation for your smartphone and make sure that your gadget will be compatible with the interface used. In some documents, the manufacturer may specify a USB host instead of OTG cable technology;
Incorrect formatting – often, the default settings of the phone do not allow it to read the file partitioning of the flash drive. There are two ways to solve the problem. In the first case, you can format OTG to an understandable version for the gadget. In the second case, you need to "teach" the phone to see the file system of the portable cable;
A portable hard drive needs too much power – as a rule, OTG technology is much more power-consuming compared to a conventional flash drive. The smartphone simply does not have enough power to run the drives inside the HDD. As a result, the cable will not work. To solve this issue, you need to use an external power supply for the Android;
Hardware malfunctions – there may be factory errors and defects in the smartphone itself. The cause of failure may be damage to the gadget.
Using applications that allow your gadget to open flash drives of similar formats. There are quite a few variations. One of the most popular versions is OTG Disk Explorer Lite;
When using a cable to watch movies, you may also encounter problems. This is due to the lack of special players designed for OTG technology. Other versions simply can not fully open the audio tracks, as they do not have built-in codecs;
Sometimes problems occur when working with documents. To maintain normal functionality of your device, you will also need additional programs. One of them is Polaris Office.
The main problem of the cable malfunction is the mismatch between the file systems of the gadget and OTG. Phones are likely to support the FAT format. You can check what format is represented on the portable flash drive using a PC. Click on the category "properties" in the appropriate explorer. After that, a window will open with information regarding the file systems and the size of the drive.
Commonly, portable devices work with the NTFS file system. Change the system to one that your smartphone understands. You can do this by formatting and erasing all data from the device.
Note, however, that such manipulation has one significant disadvantage. The technology will not be able to work with files larger than 4 GB. This is not critical but may cause inconvenience for fans of watching movies in high quality. The NTFS file system has no such flaws, so many users prefer to teach their Android to read this system.
To do this, you only need to download the appropriate program that allows you to mount the file system to recognize Android. Such programs are usually free and very easy to install.
How to solve problems with high power consumption – options:
Using a USB hub. It is an ordinary USB, but it has an external power supply. This makes it possible to connect several gadgets at once. There is no loss of speed. The disadvantage is the use of an additional socket and the risk that your device does not support the USB hub;
The use of HDD with an external power supply. The model has two USB connections (one for the Android, and one for the charger).
An alternative to the OTG system is flash drives with built-in WiFi. They are self-contained and communicate with the phone device through a wireless network connection system. This system is a full-fledged analog of OTG cable. Thus it can help you connect several gadgets simultaneously. This does not significantly affect the speed of the Internet and the functionality of Android.
