Android phones have always stood out for their flexibility and customization, especially when compared to iPhones. You can always install a wide range of third-party apps and launchers to shape the experience exactly the way you want. This openness makes Android devices incredibly powerful for people who like to get more out of their phones. That’s also why a small accessory like this makes so much sense. It can turn your Android smartphone into a portable, computer-like setup, even if you don’t have a flash drive handy, making your phone far more capable than you might expect.
Different types of USB OTG connectors
Picking the right OTG for the job
OTG (On-The-Go) adapters connect directly to smartphones and tablets and are usually classified by the type of port they use.
- Micro USB OTG: These were commonly used with older Android smartphones that came with Micro USB ports. This port could let you plug in a pen drive, keyboard, or mouse to transfer files or type more comfortably.
- USB Type-C OTG: This is the most common type today. Most smartphones and tablets that you and I use, such as the Pixel 10 series, Samsung Galaxy S25 series, OnePlus 15 series, and even the iPhone 17 series, all use USB Type-C ports. A Type-C port lets you connect USB drives, controllers, and external storage, and even charge smaller gadgets like earbuds directly from your phone. If you are curious about how USB-C works and why it has become the standard across devices, this guide breaks it down for you.
- Y-Splitter OTG: This type of OTG comes with multiple ports instead of just one. It may include a mix of USB Type-A, Type-C, or even Micro USB ports. The idea here is convenience. For instance, you can connect a mouse and a keyboard at the same time, or plug in a USB drive while also powering another device. It is especially useful if you want to use your phone like a mini workstation.
- Dual Drive OTG: These are flash drives with two collections built in, usually USB-A on one side and USB Type-C on the other. They are perfect if you frequently move files between devices. For instance, you can copy photos or videos from your phone and then plug the same drive into a laptop or desktop without needing any extra adapter.
Each type serves a different purpose. Overall, it makes your smartphone or tablet more flexible and useful in everyday situations.

How one small accessory makes your Android phone smarter
Nowadays, the most commonly used OTG accessory is the USB Type-C OTG, mainly because almost all Android phones now come with a Type-C port. This allows your smartphone to take control of a USB connection, rather than relying on a computer. It is especially useful when you do not want to carry a laptop or prefer getting things done directly on your phone. Simply put, your phone becomes the one in charge and can directly control and use other USB accessories.
With a Type-C OTG, you can connect keyboards, mice, game controllers, USB devices, and even some audio devices straight to your phone. Once connected, your smartphone starts behaving like a portable mini PC.
If you are using an older phone, you may need a USB-to-Micro-USB adapter, while newer phones will work with USB-to-Type-C OTG. Setting things up is straightforward. This guide will detail how to connect a keyboard to your Android phone.
This adapter earns its place
How OTG quietly turns your phone into a do-it-all device
Using a keyboard with your smartphone makes a lot of sense when you have long typing sessions ahead. Writing emails, editing documents, or replying to messages feels far more comfortable than typing on a touchscreen. This setup works even better on foldable phones like the OnePlus Open or the Samsung Galaxy Z Fold, where the larger display, combined with a physical keyboard, gives you a near-laptop-like experience. Adding a mouse takes things a step further, making navigation smoother and turning your phone into a proper mini workstation.
OTG is not just about work, though. You can connect a wired game controller and play your favorite games with better control and improved precision. Honestly, playing them on your phone feels far more immersive.

It is also incredibly handy for quick file transfers. You can move photos, videos, or documents between your phone and USB drive in seconds, without needing a computer or cloud storage. On supported phones, OTG can also enable reverse charging, which comes in handy when you need to top up smaller gadgets like wireless earbuds or fitness bands when you’re in a pinch.
Overall, the USB Type-C OTG makes your Android phone far more versatile, allowing it to adapt to different situations with ease. These are just a few everyday examples. This detailed guide walks you through several more practical and genuinely cool ways to make the most of OTG on Android.
A small reminder of why Android is so flexible
Android phones have always been capable, but OTG adapters push that flexibility even further. Being able to plug in a keyboard or mouse when it matters, or switch to a wired controller for a gaming session, genuinely changes how you use your phone. What stands out is how it all works. Each small use case reminds me of how Android’s openness matters and how a simple accessory can quietly turn your phone into something far more powerful than it already is.
