Cellphone repair questions? Ask a cellphone technician ASAP
Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.
There may be interference from a radio source; does the problem only happen at certain locations?
Yes, in theory you could shield it from interference, however that would also prevent it from receiving and making calls, messages, etc.
No, software will not work in this instance.
It must be a physical barrier. Aluminum foil will block radio frequency waves so it will work.
Since aluminum is a conductor of electricity, it forms a barrier often called a Faraday Cage, entirely stopping the radio waves.
Simply get a sheet of aluminum foil, and wrap the cell phone in it.

The ear buds are not connected to the antenna, they are only connected to the audio circuitry so they do not need to be covered.
If it only happens in certain areas then yes it is interference.
It is because the speaker is active and picking up interference.
You are welcome :)Have an excellent day!Pete.
