I recently upgraded to the HTC One M8 from an LG G2. I'm finding the M8 doesn't do as well as my G2 did for reception/signal strength. I'm within my return period so I'm considering switching to a different phone. I'm considering the LG G3, Samsung GS5 and Iphone 6. Which of the three would you recommend strictly on a reception basis? I prefer the look and feel of the G3 and iphone 6 over the Samsung, but more important is holding a signal.
