I noticeh a strange behaviour on my P6pro. The signal strength in my home is -103 to -109 dBm, far too low. However, each time I turn flight mode on and off, it shifts to -85 dBm every time, but after 20 seconds it shifts back again to below 100. Anybody else seeing this pattern? I have updated to the July update, but the pattern were the same with the June update as well.
