Introduction to Bluetooth troubleshooting

Detachment of the BT antenna.
Malfunction in the BT ASIC, BB ASICs or Phone's BT SMD
components.
The main issue is to find out if the problem is related to the BT antenna or related to the BT system or the
phone's BB and then replace/fix the faulty component.

Description
This would most likely happen if the device has been
dropped repeatedly to the ground. It could cause the
BT antenna to become loose or partially detached
from the PWB. (see the following section for details
on BT antenna HW and mechanics)
This is unpredictable and could have many causes
i.e. SW or HW related.
