So, my question is about the physical (USB) keyboard which is not working anymore on Samsung phones. Previously I just had to plug the USB receiver to the OTG adapter and it worked flawlessly. Now, although the phone "sees" the physical keyboard in settings, it does not work at all.
Same results with S21 One UI 6 and S24 One UI 6.1.
If anyone has an info/solution... Tnx.

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.
