  1. I’ve had a number of iphones–the 7 is without a doubt the worst regarding sound quality and connectivity. I rarely get through a call without loss of the call or distortion so great the call is a burden. Awful, awful, awful.

    • We hear you, Jim. It seems that they chased flashy improvements while neglecting fundamental phone features.

      • But I can’t believe they can sell you a phone for £850 that doesn’t make calls properly and your stuck with it!!!! In this case you should be given a full refund as it’s unfit for use
