A sensitive soul. UPDATE: Android problems?

I bought the Withings device because I have a wireless scale from Withings use for several years, the data have nicely summarized thus an app. Furthermore supports the Withings app Apple Health, as can be on an iOS device this data with data from other devices such as combined (eg a fitness tracker).

The device measures in my opinion, quite precisely, I use the automatic mode (measured three times, calculates the mean value) in combination with an Android device (the future of OA reasons iOS).

It is extremely sensitive: the smallest issues with the seating of the instrument, in 30% of the determined measurement (try), with me, a measurement can not be completed, due to unknown problems. The very annoying, especially when you are in automatic mode, and the third of three measurements fails, everything back to the start.

I'm quite unhappy because of this problem.

UPDATE: I am for various reasons about a week ago on iOS (from iPhone to Nexus 5 6 Plus) changed since daily measurements without problems. That seems a problem in the Bluetooth communication with Android devices to be (or problems with the app). Although Withings changes primarily with iOS on this unit, so Android is however also officially supported, but seems to be working poor.
