Thanks, I should have been more specific. The Z813 has 5.0.2 and a 16 GB SD card, Memorex, I think. The Z987 has a 32 GB SD card from Adata. The Z813 has "low memory" ( yeah, right with roughly 8 GB left, which is essentially the same as the phone's actual memory). I tried to email between the two but the smaller phone claims not to have enough memory. Does either of these models have NFC and/or Android Beam?
