Have any of you had problems with your Lumia 640 Speaker? I have and a hard reset didn't help me at all. So I claimed warranty but I haven't had someone take me to a UPS Store to ship it, so today while I was bored I take my phone and connect to my PC and start up Windows Device Recovery Tool. I reinstall the software, and SHAZAM! The speaker works again! Now if this doesn't work for you then I'm sorry but you will have to claim it under warranty and ship it out to Microsoft. Thanks for reading!
