It will be impossible to detach the camera and the USB. You might not always be able to replace the camera. Sometimes, the problem runs much deeper than a replacement. If t works well here, the problem is the phone. If you can safely remove the cable, once again test it with another device. 80% of the time, the line itself is the issue.
If it works with the new one, you know where the problem lies.
First, check if the OTG adapter is working fine. To rectify this problem, there are two ways. The problem lies with the cables and not the internal parts. As mentioned, this is the most common problem. Both these could stop working over the years if the cable is not right. Your OTG adapter and the endoscope should be of the same brand and company. This is one reason why most of our earphones get spoiled too. Therefore whenever you are using the cables, try to keep them straight. If this increases any further, the wire can break eventually. This means that the internal wiring too is bent. If we use the USB endoscope a lot, there might be bends on the cable. Sometimes, people use too many other company products. You get different sizes, but it should be compatible with your device. This is a piece of cable that is easily connected to any device you want. Aside from this, you will require an OTG adapter. You need the main cable to connect the endoscope to your phone or computer. This is one of the biggest issue of USB endoscope camera not working.
