I hope this is only happening to me, I got the j70 of my sister as a present.
At first it was great, until I put it on charge and the battery fell out, and it was still on.
The next day I put, message memory to phone. It said my sim could hold 250 messages and my phone could hold 8. I thought hmmm just a lil mistake no harm.
then shurtly after all my messages were deleated, I couldnt hold anymore and all my phone had been reset. As I help my numbers on the mobile not the simcard this bugged me. I took it to a phone shop, for my friend to look at it, he told me I needed a new one. and it got on my nerves.
So I would point out, go for the Sony Z7 . its better that the sony cmd j70 or j7
