@peterleinchen So when you put off SD swap, all data there is moved to eMMC swap, and afterwards when you put on SD swap, old data is on eMMC one and new data is writed to SD one.

I see a problem: eMMC will be used to have the old data after the refresh, and while your programs need that old data to be readed and loaded in RAM, you will be using some of the eMMC, so your mobile will be a bit slower (remember we use swap on SD for never using eMMC for swap and at the same time data from /home or /MyDocs (in eMMC too), soo we get less stress in eMMC). It's not a big problem, but well, would be better if you only use SD always.
