We have two Motorola Droid RAZR MAXX (one is an HD). We use our phones with Bluetooth ear pieces every night 2 - 2.5 hours each night. Recently, past month or so, when using the our phones with Bluetooth devices, the Bluetooth will suddenly drop and the phone kicks over to Speaker (but when you look at the phone, the in-call display shows it is still using BT). Most often, we can use the in-call display to switch from BT to Speaker and then back to BT. However, this is not always successful - tonight for example, the BT was dropped and I can't get it to reconnect. There has also been instances where the phone (Droid RAZR MAXX HD) has disconnected with Dodge U-Connect.

Droid RAZR MAXX - Plantronic Voyager
Droid RAZR MAXX HD - Plantronic Voyager Legend Pro
As a matter of troubleshooting:
1. BT Cache has been cleared
2. Phones have been Powered Off and back on (daily)
3. BT are fully charged
4. One BT is brand new (Plantronic Voyager Legend Pro)
5. BT devices are current on Firmware
6. It's clearly not the BT devices
7. Both phones are current with software provided by Verizon:
Android 4.1.2
System version 9.18.94.XT926.Verizon.en.US
8. Phones are well cared for, no damage and look new. No drops, no abuse - just responsible users.
Yes I have looked at forums and other help pages.
