I recently installed iOS7 on my iPhone 4. I have Microsoft sync in my car and connect my phone through the car's bluetooth to listen to music and talk on the phone. My problem is there is very noticeable skipping during songs while they are playing through the speakers. I never had this issue before when my phone was using iOS6.
I have backed up the phone through iTunes (most recent update) on my PC laptop (Windows 7).
I have tried restoring the phone.
I have not had any other issues with the update.
I have noticed that there is a slight hesitance when running multiple applications.
I have closed all the idle apps.
It is a refurbished phone.
I tried restarting the phone.
Are there any other suggestions to try and stop this from happening?
