I bought one of these little boombox bluetooth speaker w/ mic. It paired & connected no problem with my Samsung Galaxy S3 but as soon as it did, it killed my Galaxy external speaker and nothing comes out of the bluetooth speaker. I tried it with my wife's iPhone & co-workers' iPhone and it works great. I tried everything I could think of to get my galaxy's exterior speaker to work again and nothing but I eventually figured out that the only way I could was to remove the battery for a few seconds & re-install. I thought the problem might have been the bluetooth speaker so I returned it and bought a different brand name and same problem. Does anyone have any suggestions, please? Thanks in advance.
