Android (Phones) and the Question about ROM and RAM
Pretty much every day I see people complaining about the ROM and RAM sizes of their Android phones and tablet pcs. I'm even being called a liar when I state in some of my videos that a device XYZ has XXX MB of RAM and XXX MB of ROM.
You wouldn't believe how rude some people can be, blaming ME for problems they are having with their devices, just because I did a review video of some sort and they are not happy with their purchases.
People feel cheated because their AVAILABLE memory size is not the size the device was advertised by.
Are we being cheated? Is that some sort of scam the Chinese manufacturers are trying to pull off?
MY answer is NO (in 99% of all cases) ;-) Here are two examples that might help you understand what's going on with the actual (available) ROM and RAM sizes and this is NOT just a "Shanzhai product) issue as you will see:
"…. A good example is the HTC Desire which has 512MB ROM according to the specifications page but according to PCMag there is “only 117MB of available internal storage“…"
"…I have a Nook Color with Cyanogenmod 7.2 (on mSD), and Nook Color is supposed to be 512MB of RAM (says so on product's page).
When I open Menu (on bottom bar, while on desktop) > Manage Applications > Running, it says on the bottom left 95MB used, and on the bottom right it says 174MB free…"
"…Although your device may have 512 MB of RAM in it, the settings almost always report the RAM that is available to user processes, not all of the physical RAM. This means that it won't report any memory that is being used by:
Although this memory is not reported, it is being used by the system. Reporting it in a system monitor is simply not very relevant because the OS is going to basically keep it for itself forever (after all, the OS needs RAM to run properly, too). There is really no way that you can get this RAM "back" from the system, but you wouldn't want to anyway since your phone would basically stop functioning without it…"
So, PLEASE keep that in mind, thanks :-)
