Why is my phone's Wi-Fi and Bluetooth fluctuating?
I recently replaced my Nokia‘s battery at an authorised service centre. Even though the battery is working properly, I’m experiencing troubles with Wi-Fi and Bluetooth connectivity. The distance I can roam around the router has reduced significantly and the same issue is also experienced with my Bluetooth earphones. I cannot conclude whether this is a software issue or some mishandling while hardware reassembly. Any help would be appreciated.
