Droid maxx dropped calls , calls dropping in and out during conversations, Signal fluctuating, apps constantly updating sometimes 2 or 3 times daily. THIS HAPPENS ON ALL 4 DROIDS I have already had one droid replaced and the new one does the same as the old one that was replaced. I have went through the boilerplate responses to reboot, factory restore and so forth. I have even added the network extender to my home,( joke, must be within 15 feet to connect and if you return home your call has to drop to connect to home extender, just FYI for anyone thinking along this line. 15 feet does not reach across my living room much less the house. Also the extender does not address this issue happening EVERYWHERE we go. Cannot use the blue tooth devices we have and I have multiple high end devices that have the same issues on all phones not just one of them. It is about time to end my 15 year relationship with Verizon, in this time the last 6 months has been the worst service I have received from Verizon.
