I have an iPhone 6+ on Verizon Wireless in the Los Angeles area. Normally I have always gotten full bars in my area. However, with the 6+, I noticed I only have 4/5 dots for signal reception. If I restart my phone, I get 5/5 dots after the restart for 2-3 minutes or so, and then it falls back to 4/5 for the rest of the day. Very rarely do I spontaneously get 5/5. Is this normal? If I put my sim into an S5, I get full signal on that phone, but I don't know if they measure it differently.
