According to CDD document, it is stated below
"Device implementations MUST have at least 340MB of memory available to the kernel and userspace. The 340MB MUST be in addition to any memory dedicated to hardware components such as radio, video, and so on that is not under the kernel's control."


MY Understanding is:

340 MB is required for both user and kernel space. 340 MB is for hardware components ,

So, in total minimum 680 MB

NOTE: Please correct me if my understanding is wrong ?

But, if i look at mobiles that are available in the market, they are not compliance with the requirement.

For example:

HTC ONE V , has 512 MB of RAM, but still runs android 4.0.3 , in which the requirement is 680MB.

Considering above, how the OEM vendor passes compatibility test?
