Okay, I just want to make this clear about the RAM business in the Samsung Wave/Wave II
Both phones physically have 512MB of Mobile DDR RAM
The fact is (if you are on Bada 1.0-1.2) 256MB of RAM is reserved for Bada OS along with the libraries and service layers. This also includes the Bada Default apps (such as Mail, Messaging, IM, Social Hub, Facebook/Twitter, Dolfin, TouchWiz Music, Gallery etc.)
In Bada 1.0-1.2, the phone can only utilize one of the 2 parts of the RAM (this is because how the OS is designed).
Basically, when you have a install app running, and switching to a Bada native app, the install app will (Suspend). This will suspend the RAM (RAM-reserve switching). One of the parts can be used. But the certain functions of Bada will run in the background, not all (some of these services are suspended as well).
Within the Bada OS reserved RAM, approximately 70MB-90MB (depending on numbers of widgets, homescreens and app main menus). For reference of browser, Dolfin will take about 12MB-18MB of RAM to show about:blank (OS 1.0-1.2). Enabling Flash will add about 3MB-5MB to show the blank page.
TouchWiz Music Player takes about 10MB-16MB depending on how many songs you have in your Library and how many Cover Art (also if you turn on the Visualization). SRS Mobile Surround and EQs do not really affect the RAM since they are built into the player itself. (Not turning it on/turning it on RAM usage is very subtle). It does however take more CPU resources and shortening battery life.
**NOTE: Java based software is part of the OS layers and is unaffected if you install third-party Java apps. The Java Runtime as a whole is part of the Bada default services**
As of now, I have no information if Bada 2.0 will unify the RAM "partitions" into one, but if it does unifies along with better OS optimization (memory leaks and over-usage), then things will be much more smoother and less confusing and enriches the user's experience.
Thanks. Hopefully this clears it up.
