8 different devices of the same SM-S916U showing for location in Google maps

When it comes to visits and routes for Google maps there are 8 different SM-S916U's contributing to the location. Why is this.. I feel like I've been hacked

Definitely a cause for concern I would goto settings than Google account folder and check the devices listed there and remove any that's not your phone or phones seems somehow your device is being shared question is why

Its just logging different sessions of the same device. If its logging the locations you were actually in at rhe time, I wouldn't be too concerned. If you have doubts, you can log them out of your account. If you log out the wrong one, the worst that happens is you will have to log back in.
