Hello, i'm a recent owner of an unlocked European LG G3 D855. I noticed that when i'm picking up the phone to do something the signal drops significantly. If i leave it on the table, the signal bars raise. The problem seems to happen only when holding the phone by the back-bottom part. Anyone else having the same problem? With my previous phone i had 3G signal with 3 bars and now with the LG i have 1 bar 3G signal and when holding it drops to EDGE.
