"Teleporting" between multiple devices in Records.json

[ItsVipra]

Describe the bug
When importing from a Google Records.json file, positions recorded from different devices are treated as if they were the same.
This results in "teleports" between both devices, inflating the distance travelled massively (see screenshot).

Version
0.15.3

To Reproduce
Steps to reproduce the behavior:

1. Import a Records.json containing points from multiple devices. e.g. :

{
    "latitudeE7": 123456789,
    "longitudeE7": 123456789,
    ...
    "deviceTag": -97XXXXXXX,
    "platformType": "ANDROID",
    ...
    "formFactor": "PHONE"
  }, {
    "latitudeE7": 987654321,
    "longitudeE7": 987654321,
    ...
    "deviceTag": -55XXXXXXX,
    "platformType": "ANDROID",
    ...
    "formFactor": "TABLET"
  },

Expected behavior
I expected implausible changes in position to be filtered out or data from unreliable devices to be filtered (automatically or manually).

Shower thoughts: need option to detect active device (like moving more than 50m/150ft) and prioritize its info for next 5 mins. But looks a little bit process heavy

I'll think what I can do to support multiple devices for one user, thanks for the report
