Hello. I'm not a very technical person and I'm looking to buy my first android phone but I don't get the purpose of partitioned 'internal' and 'phone storage' memory on some handsets. I'm after a budget device (about £100) to put my sim in, for use mostly with SMS/whatsapp messaging and emailing, no real need for games or all kinds of heavy apps so I figured an 8gb device with 1gb RAM should do me fine even with a 1-2gb taken for the OS. Aside from adding an SD card if I need it, is it going to be a problem having a partitioned overall memory? I understand some things go on one part and other things on another, but if I'm only left with 2/1/less gb on the relevant partition for messages would that become an insufficient amount after a short space of time? Thanks.
