Users of budget tablets often encounter questions related to connecting the device to other gadgets. The model DEXP G M2, despite its availability, requires the right approach to setting up interfaces to ensure stable data transfer. An incorrect configuration may result in a computer or other smartphone simply not seeing your tablet in the system.
In this guide we will look at all the nuances of interaction DEXP G M2 with the external environment. You'll learn how to enable hidden developer features, what drivers you might need, and how to avoid common syncing mistakes. This will allow you not only to transfer files, but also to use the tablet as a peripheral device.
The setup process does not require in-depth technical knowledge, but attention to detail is crucial. Each step must be performed sequentially to avoid failures in the operating system Android. Let's proceed to a detailed analysis of the connection procedure.
Preparing the device and checking the cable
Before trying to connect DEXP G M2 to a computer or other smartphone, you need to make sure that the physical interface is working properly. Often the problem lies not in the software settings, but in a simply damaged cable or dirty connector micro-USB. A visual inspection of the tablet port will help eliminate the presence of dust or oxidation of the contacts.
Use the original cable included in the package, as third-party accessories may only support charging mode, ignoring data transfer. If the original cable is lost, choose high-quality analogues that support the standard USB 2.0 or higher. Cheap wires often do not have internal lines for transmitting data signals.
Turn on the tablet and unlock the screen. Connection of a locked device may be restricted by the system in some security modes. Make sure the battery charge level is at least 20% to avoid sudden shutdown while setting up settings.
⚠️ Warning: Using damaged cables may cause a short circuit and damage the tablet's power controller DEXP G M2.
Before connecting, wipe the micro-USB connector with a dry soft brush to remove lint and dust, which often interfere with tight contact of the plug.
Activation of developer and debugging mode
To fully control the device via a computer or to connect specialized software, you must activate the hidden menu. In the standard state Android restricts access to system functions for security purposes. To open access, go to the section Settings and find the item About tablet.
Inside this section, locate the line Build number. You need to quickly click on this inscription seven times in a row. The system will count the clicks and issue a notification that you have become a developer. After this, a new section will appear in the main settings menu For developers.
Go to the newly created menu and find the switch USB Debugging. Activate it by confirming the action in the pop-up window. This setting allows the computer to send commands to the tablet and access the file system at a low level.
- 📱 Click on “Build Number” 7 times to activate the menu.
- ⚙️ Turn on the “USB Debugging” toggle switch in the new settings.
- 🔒 Confirm permission to debug from this computer when connecting.
After enabling debugging, each time you connect to a PC, a request to confirm the RSA key will appear on the tablet screen. Never confirm this request unless you initiated the connection yourselfas this may be an attempt at unauthorized access to your data.
Selecting a USB connection mode
When you physically connect DEXP G M2 to a computer, the system often defaults to the "Charge Only" mode. This is done to protect data, but to work with files you need to change this setting. Pull down the notification shade from the top of the screen.
Find the USB connection notification. By clicking on it, you will see a menu for selecting the operating mode. To transfer photos, videos and documents, select mode MTP (Media Transfer Protocol). In some versions Android it may be called “File Transfer”.
If your goal is to use the tablet as a network card to distribute the Internet to a computer, select mode RNDIS (USB modem). To debug applications, leave the debugging mode active, but for the average user, MTP mode is optimal.
| USB mode | Purpose | Transmission speed |
|---|---|---|
| Charging only | Device power | No data transfer |
| MTP (Media) | File transfer | High |
| PTP (Photo) | Import photo (as a camera) | Medium |
| RNDIS | USB modem (Internet) | Depends on the network |
☑️ Checking the connection
Installing drivers on the computer
Sometimes the computer does not see DEXP G M2 even after selecting the correct mode. This indicates that the necessary drivers are missing in the Windows operating system. Unlike popular brands, drivers for budget devices are not always built into the system automatically.
Try connecting the tablet to a different USB port, preferably a black one, not a blue USB 3.0 one. Old controllers on budget devices may not work correctly with new port standards. Open USB 2.0 black, not blue USB 3.0. Old controllers on budget devices may not work correctly with new port standards. Open Device Manager on your PC and check for unknown devices.
If you see a device with a yellow exclamation mark, try updating the driver automatically. In rare cases, you may need to install a universal driver Google USB Driver via the Android SDK, but for DEXP G M2 standard MTP drivers are usually sufficient.
⚠️ Attention: Avoid downloading drivers from dubious sites, as they may contain malware that can steal data from your computer.
What to do if the driver is not installed?
Try to manually specify the path to the driver in Device Manager by selecting “MTP USB Device” from the list of compatible Microsoft devices.
Connecting to another Android smartphone
Users people often wonder whether it is possible to connect DEXP G M2 to another phone based on Android. A direct tablet-smartphone cable connection is possible, but requires an OTG adapter. The tablet must act as a host, which is not supported by all budget models.
If your device supports USB OTG, you will be able to connect flash drives, mice and keyboards. However, transferring files directly between two Android devices via cable often doesn't work without root access. It is much more effective to use wireless methods.
To quickly transfer data between DEXP G M2 and a smartphone, use technology Android Beam (if available) or the built-in “Quick Send” function in the “Share” menu. This will create a direct Wi-Fi access point between devices.
- 📡 Use Wi-Fi Direct to transfer large files without the Internet.
- 🔌 To connect peripherals you need an OTG cable.
- 🚫 Direct file transfer using a phone-tablet cable is often is impossible.
Solving problems with device detection
If the computer makes a connecting sound, but the tablet does not appear in “My Computer,” the problem may be in the file system. Make sure that the tablet is not in storage mode, which is outdated in modern versions Android. Also check if the security lock screen is locked.
Try restarting both devices - the tablet and the computer. This resets USB Manager Service errors. In the developer settings, you can try changing the default USB configuration to MTPso that the system does not reset it to charging mode.
As a last resort, reset the network settings on the tablet. This will remove saved Wi-Fi passwords and Bluetooth settings, but may restore the USB stack to work correctly. Go to Settings → System → Reset settings → Reset Wi-Fi, mobile data and Bluetooth settings.
Rebooting both devices solves 80% of problems with tablet detection in Windows without the need to reinstall drivers.
⚠️ Attention: Resetting network settings will delete all saved passwords for Wi-Fi networks, be prepared to enter them again.
Frequently asked questions (FAQ)
Why does the computer see the tablet only as a charger?
