Another question: when the device went through QC, what were the parameters? ie. Which apps did you have installed? Did you mimic real-world use?
Storage used with approx. app data (Percentage based on 1.00GB, actual storage 0.98GB)
* Google Chrome - 8% (6% app, 2% data)
* Google search app [GAPPS] - 5.5% (4% app, 1.5% data)
* Google Play Services [GAPPS] - 4% (2.4% app, 1.6% data)
* BBM [update] - 5% (3.6% app, 1.4% data)
* Twitter [update] - 4.7% (1.7% app, 3% data)
* Maps [GAPPS]- 2.6% [I have not even used the app, so the data usage is low] (2.4% app, 0.2% data)
* Play Store - 1.1% (1% app, 0.1% data)
These base apps take a total of 30.9% of the storage [Not including wallpapers, and other bundled apps]
Then there are the system apps (no app/data breakdowns)
* Settings - 2%
* Google Text to Speech - 2%
* Android System - 2%
* Dialer - 1.1%
* Messaging - 0.9%
... The rest get boring. Altogether, that accounts for 19% of the storage space.
Then users want to be able to use other apps (because we have the right to do so). Now as we know, apps nowadays are not small. And some of these apps cannot be moved to the phone storage.
That means with the standard installed apps & services, you are left with 50% or 500MB, excluding internal services and so on.
These are just overview checks. I have not gotten into all the details of what the system uses and so on.
