Galaxy Tab S7 - does it support wired keyboard via USB OTG connection?

[MikeCW]

I've tried connecting an external keyboard, which I've used successfully via an OTG adapter on my old Tab S2, to my Tab S7 adding a micro-usb to Usb-c adapter, but the keyboard does not seem to be detected. Does the Tab S7 support wired keyboards connected via an OTG adapter - just wondering if I just need to get a direct USB to usb-c otg adapter)?

Any guidance would be gratefully received. Thanks.

@MikeCW Hello, do you have the option Show keyboard on screen activated? It is located in General Administration / Physical keyboard.

Hi - I've tried with that option both activated and deactivated - the "Physical keyboard" status persists as 'not connected'.

Hi- thanks for the thought, it jogged my memory that I had an OTG  USB-A to USB-c connector that came with my S9 phone - I tried that on the S7 tablet an it worked - it seems the combination of the USB-A to micro-usb connector I had previously used with a Tab S2, and a micro-usb to usb-c adaptor is not the equivalent I thought it would be!

OTG Keyboard and Mouse Connection Issue on Samsung Mid and Low-Range Devices and Its Solution (Tested on Samsung Galaxy A15)

Samsung's mid and low-range devices sometimes fail to properly recognize or operate external keyboards and mice when connected via OTG. However, testing on the Samsung Galaxy A15 has revealed a successful workaround for this issue.

Solution 1: Using a Bridge Connection

When a keyboard or mouse is directly connected to the OTG adapter, the device often fails to recognize it. However, creating a "bridge" connection has been observed to help the device properly detect these peripherals. Here's how to do it:

1. Connect the OTG adapter to the phone.

2. Instead of plugging the keyboard or mouse directly into the OTG adapter, use a USB female-to-female adapter or a similar converter.

3. First, connect the keyboard to this adapter, and then plug it into the OTG adapter.

After using this method, the device successfully recognized the keyboard and mouse. Additionally, once this initial connection was made, subsequent direct connections (without the USB female-to-female adapter) also worked. This indicates that after the first successful detection, the device no longer required the bridge. This solution was tested and confirmed to work on the Samsung Galaxy A15.

Solution 2: Using a USB Hub

Another effective solution is using a USB hub. Follow these steps:

1. Connect your keyboard or mouse to a USB hub.

2. Then, plug the USB hub into the phone using an OTG adapter.

This method also successfully allowed the device to recognize and operate the keyboard and mouse. It was tested on the Samsung Galaxy A15 with positive results.

While these solutions may not work for every device, they have proven effective on the Samsung Galaxy A15. If you're experiencing similar OTG connection issues, trying these methods

could help resolve the problem.
