I've had my Z5 for about 6 months, it is Wednesday evening now and since Monday afternoon I have been having some issues with my phone, although I had previously had no issues.
On Monday afternoon I was messaging a friend when suddenly my phone was off, it did not take the time to shut down. The screen was stubbornly black for several seconds before I managed to get it turning on again, although when it did it no longer registered the SIM card. Just restarting the phone did not change this, however removing the SIM and putting it back in while restarting did.
Over the last few days, this has happened maybe 10 times total, although more often the phone suddenly 'loses' the SIM without the phone switching off.
I have attempted to clean the SIM slot but I am still having the same issues.
