bluetooth - sudden reduction in range
I have an iphone 4 and a set of LG HBS700 bluetooth headphones.
they worked great up until about a week ago. I could shove my phone in my bag and listen to my music on the way to and from work without an issue.
Suddenly the range on them has diminished considerably. If I put my phone in the same pocket in the same bag that I've been using for the past year , the connection splutters to the point where the pairing between them fails.
Initially I thought they were low on charge but leaving them charging overnight didn't help. I've changed nothing in my set up. I've not upgraded the OS on my phone. I've not suddenly taken to wearing a lead lined scarf.
Any thoughts on what the problem might be and possibly a solution?
Appreciate any ideas
