Chosen Solution

Hi!I cannot specify the model because it’s not on the list (Unitech EA500)I need to know, where is the Bluetooth module/chip location, usually on an Android device… ¿On the motherboard? At the lower part where the antenna?I have lot of spareparts of that phone, because it is the one that is used on my office, and i will replace some of them. Thank you for your time. Regards.Edit: Just to clarify, the problem is that blueetooth is not working. You can activate it, change settings like name, turn on visibility, but it is not able to find any device, and no device can find the phone even with visibility on. SOLUTION: One of the pins of the motherboard, which connect to the bluetooth antenna on back cover, is stucked down.
