I sent my moto x back to Clove,from where I purchased it.They ran some tests and told me everything was working fine.Then asked if I wanted it returned or sent to Motorola and as I knew it wasn't working fine I asked them to forward it to Motorola.Approx 2 weeks later I have just received an email from Clove telling me Motorola are now sending me a REPLACEMENT handset.This must mean there was a problem with the handset.So, don't always believe what a seller tells you.
