Darla, I routinely do this when replacing ports, especially Samsung. Obviously it has to be done carefully, but I find that even brand-new ports are somewhat loose and can be tightened this way. It could be done without replacing the port. I remove the circuit board from the tab or phone, insert a micro USB cable (that is NOT attached to power!), and then carefully and gently use a pair of pliers to compress the port toward the board from both top and bottom. Then I check tightness and adjust accordingly. If your port is really loose, this may not help. You may need a replacement, which requires soldering under a microscope. But if it’s only somewhat loose, it may be enough, at least for a while. I am a phone/tablet technician who does microsoldering, and has replaced many Tab A ports.
