Ok, took a little investigating, but here's my conclusion. The cell phone has a magnetometer/compass. When two devices are i close proximity, the drone and phone, there may be interference. The Lenovo Tab 3.7 does NOT have a compass/ magnetometer. The tab 2 does, but for reasons that are not clear, it was removed on the Lenovo.
For high accuracy location, the magnetometer is needed but is will cause some interference when two such devices are near each other.
Also, review the following:
Safe distances for compass calibration
6” (15 cm) minimum: Metal rim glasses, pen/pencil, metal watch band, pocket knife, metal zipper/buttons, belt buckle, batteries, binoculars, cell phone, keys, camera, camcorder, survey nails, metal tape measure.

that use a magnet to hold the stylus.
