but I missed MicroSD slot. I think my requirement is simple: not too wide (<=70mm), has 3.5mm audio pack, and has MicroSD slot.

and end-up only Sony products comes out. and I sacrificed performance for a shorter phone so I bought Xperia Ace III.

but I don't know when will my ISP shutdown GSM-1800. If this happens I have to buy Xperia 10 series then.
