1: I keep getting a sim card error where it says no sim is inserted. I am aware that you are not meant to use an adapter. I am trying to work out if this is an issue with the actual physical slot being lose or if it is down to a dodgey sim. Is there a known issue where the slots need repair or is it most likely going to be the sim? I will test with another sim tonight. It's very intermittant though unfortunately and can be fine for a week and then do it. To resolve, I simply remove and reinsert the sim.
2: The ear piece (for calls I mean, i.e. not the external speaker) is distorted during calls. It's actually sounds more like the actual casing or ear piece is vibrating/resonating like a slight buzz when people speak to me. It's really annoying.
Should I just get the phone replaced? Annoying as it's such a good phone otherwise and I have paid already to unlock it.
