Have been using the Nikon SB700 flash on (D7100) hot shoe for a year, same way shooting real estate. Recently, when carrying or moving tripod with camera and flash, there are random mini flashes. Hot shoe and flash attachment do not seem loose. Flash locked on properly.

And you’re not accidentally pressing the DOF button on the camera body, right? (Hate when that happens)

Sounds like a cracked solder joint internally or a short with the connections from the flash shoe

Sounds like a hardware problem. You’ll should not get flashes, mini or otherwise, while merely carrying the camera.

Can you borrow another flash and see if it still does that with the other flash mounted to your camera? If it does it’s probably a camera malfunction. If not then your flash has likely malfunctioned.

Maybe time to contact Nikon support?

The connecting plates are attached to the ubits (body & flash) with tiny screws, tighten them, you will very likely find them a tad slack. Use ONLY a quality proper fit screw driver and don't overtighten. May solve to problem.

If the flash is working well when you take the shot my suggestion would be to remove flash when your moving around the tripod. Something when you are moving is causing contacts to be made firing the flash. Simple fix.

A similar thing happened to me for a couple times. Mine turned out to be the third party flash mount contacts sort-of sliding on what little dirt that was there and breaking contact. My fix was to clean the contacts on both parts to make a better connection. No problems since. You might try that.

Those mini flashes may be the result of the camera using the flash to focus. If your camera is set to continuous focus, the camera/flash combination may fire if moved. Just a thought.

Not even close, unless you are pressing the shutter while you move. Focus Assist is provided by infrared, not flash. You can program a button for "modeling light" which could be a possibility here if that has been done. Best of luck.

I will admit that I'm unfamiliar with the Nikon system but some of my Canon systems do indeed use mini flashes from the speed light for focus assist in dim lighting.

A flash can put a lot of strain on a hot shoe when you're moving around, tilting it, carrying it sideways on a tripod, etc. Connection problems/failure are the result. The bigger the flash the worse it is.
Better to use a flash bracket with a dedicated cord .

Wow that is annoying. Nikon has focus assist light. You can turn it off if you wish (I usually do). The option is about 5 menu levels down. LOL.
