After "Bug 1077546 - [Cost Control] Add app detail view" was landed, the difference between by application breakdown totals and the total by interface (residual traffic) is visible on the system App detail view. Now, the amount of mobile traffic of the System app that is showed on the app list differs from the amount on the app detail view. STR: 1. Make reset-gaia 2. Don't enable any mobile data network. 3. Launch Usage and pass the FTU with default values. 4. Obvserve usage is 0 5. Press home button 6. Enable 3G from utility tray 7. Keep home pressed and return to Usage application 8. Wait for chart and application breakdown 9. Go to system app and watching the amount of traffic. 10. Press on system app and compare the data traffic with the amount of traffic showed on the previous list. Expected: Total amount of data displayed in the breakdown sums up the same amount displayed in the system app detail view. Actual: There is a noticeable difference between the two totals.
Hi Salvador, Which device do you find this bug? Which version do you intend to file this bug?
We should address this problem in the back-end but solving this in the front-end, with a workaround similar to bug 1080473, involves other problems related with how to show the residual traffic in the chart. Proposed solutions include: * To not allow see details for System APP. * To include a special label inside System APP detail view saying: `Residual traffic:` and the difference. * To distribute the residual traffic each day increasing artificially by-day usage. We need som UX advice.
Hi, From ux perspective, I agree with Salva that not allowing user accesses system app. And also I'm thinking that maybe using "Others" rather than "System app" would be easier for users to understand? User won't not know what system app means in here.
Thank you Juwei, I'm taking this bug and not allowing to see details for System app as it was suggested by Mai. I'm going to ask l10n team for changing a string because I don't know if it's too late.

Created attachment 8556280 [details] video_v2.2.MP4 Hi Marina, I have verified this issue on Flame 2.2/3.0, but I can not make sure the meaning of step 8~10, I have uploaded the video of Flame v2.2 and v3.0, could you help to check whether this bug was verified pass or not? Thanks! See attachment:video_v2.2.MP4 and video_v3.0.MP4 STR: 1. Reset device. 2. Don't enable any mobile data network. 3. Launch Usage and pass the FTU with default values. 4. Obvserve usage is 0. 5. Press home button. 6. Enable 3G from utility tray. 7. Keep home pressed and return to Usage application. 8. Wait for chart and application breakdown. 9. Back to home and launch some apps to use mobile data. 10. Launch Usage app to check the data traffic. **On Flame 2.2, the amount of Mobile usage per app(235.83 KB) is not equal to the value of Mobile usage(235.82 KB). On Flame 3.0, it can't scroll the Mobile usage per app, so I can not check the amount of traffic.

Hi Sue, On the last steps you have to check the following issues: * On the App list you have to check that you see the "Others" label instead "System". * When you make clic on "Others" nothing happens. (Others doesn't have a detail screen) Regards, Marina
