Hi Sandip,

Could you provide more acceptance criteria for this user story?

Here is my suggestion:
1. User can see "1x" and "EV" indictors depending on network connecting status.
2. User should see no service indicator.
3. User can distinguish signal strength from clear x bar indicators. (x might be 4 or 5 depends on requirements)

Thanks,
Enpei

Anshul - Please confirm 8x26 will have only these 2 (user facing) states?

> 2. User should see no service indicator.
Agree.

> 3. User can distinguish signal strength from clear x bar indicators. (x
> might be 4 or 5 depends on requirements)

Anshul - Please confirm 8x26 will provide the "strength translation algorithm?" If it is same as GSM (5bars), I am not sure if the RIL APIs are same?

Sandip, I think the gaia should only care about how many signal strength bars to be shown and the logic to come up with strength translation should reside in RIL. The bug 835237 updates the interface to pass all the signal strength value from RIL to gaia and have the logic in gaia, which might be an overkill for gaia when RIL can make the decision and send the "relSignalStrength" instead.

Talked with UX and related members. 
1. Agreed to have one signal icon.  
2. With data call, it will show: 
EV
1X 
3. No data call, only signal bar.

Hi Sandip and Kevin,

How about data call dormant and active cases? What the UX behavior should be?

[Kai-Chih Hu [:khu]]

I think Neo could be the best one to answer this question?

Confirmed with Dev, current design will depend on Rx power only. Will base on this requirement to create test cases.
* >= -76,    level 5
* -77 ~ -83, level 4
* -84 ~ -90, level 3
* -91 ~ -97, level 2
* -98 ~ -104,level 1
* <= -105,   level 0

Update test case URL, yet some minor revise will be needed when UX is ready.

QA can verify this user story now.

Test completed, failed. Issues are in depend on field. (Wasabi master 20130830172300)
