Ipad mini4 asking for calibration of motion sensor during use of SafeSky and SkyDemon


I’m using SafeSky and SkyDemon on an Apple iPad mini 4.
When using SkyDemon and SafeSky at the same time (split screen) after a certain time iOS is asking to calibrate the motion sensor, see screenshot.

Even after a calibration, this message appears again and again (infrequent every 5 to 40 minutes).

Additionally both apps are loosing the GPS signal several times. But only if they run at the same time. If I use only SkyDemon or only SafeSky, I have no problems.

How can I solve this issues?

Thanks and best regards
