"...time consuming and pointless".
As a few have said, I have 128GB inserted into my phone to do with as I please - and costing much less than getting a phone with it.
When are manufacturers going to realise that charging more $$$ for memory is a losing card.
We all want better and/or removable battery, SD card slot, decent screen, and something to stop the ports degrading (e.g. wireless charging).
