WiFi Dropping when connected to Bluetooth

[Bobmeaney]

Im having a strange issue when using both Bluetooth and Wifi simultaneously.

This happens pretty regularly when using the Spotify app whilst having the phone audio connected to a Bluetooth speaker. The pairing process works without issue. However, as soon as I begin searching the app for music, and select a track for playing, the WiFi connection drops. Sometimes It eventually reconnects, other times I have to go back to settings and manually select the network once again.
During the connection drop, I can still see the Wifi network and all my other devices still remain connected. Rebooting the doesnt fix it, nor does disabling/enabling the wifi.
Would appreciate your help on this as its rendering the phone useless for music streaming!
Thanks,

Brian

Hi Jake, and thanks for the response.

I wiped and restored the phone today as instructed. Since then I have tested the bluetooth streaming, and unfortunately the WiFi is still dropping constantly.

Please advise how best to proceed.

Jake, I have just realised that I posted this in error on the Z2 page, apologies. My phone is actually an Xperia Z3, just purchased a month ago.

Does this only happen when using Spotify, or does this happen with all apps when connected via Bluetooth, say Youtube for example?

[Bobmeaney]

Jake, the only apps I have tried would be spotify and youtube, since they utilise both Bluetooth and WiFi simultaneously. 
In both cases, the WiFi has dropped several times.

This could possibly be a hardware issue with the device, in all honesty, I suggest getting the handset back to the place of purchase or contacting Sony Mobile directly to see what can be done for you.
