A major problem with Android versions before 4.3 is the lack of TRIM functionality in the operating system.
It takes longer for the system to overwrite a solid state memory location that still might contain (outdated) data (a 0 or a 1) as opposed to
a cell marked free or never used cell. TRIM works in the background to flag unused/available memory cells.
Without TRIM the tablet will eventually slow down considerably. I happens gradually, so you might not
notice much until you see the same tablet model with little memory usage. This would be a great upgrade for the note 10.1 and is the one I want
most. A poor explanation, but it is clearly explained at the link below. Some people think a reformat of the memory (and a pain-in-the-*** reinstall)
performs the same function, but that is not true. A reformat WILL bring back the performance (I think) but it will also shorten memory life.
(this is why we don't defrag solid state drives)
