Dear developer,
When gaia got 'wcdma/gsm-auto' from lower layer, it displays "gsm prefer" to user. Is that alright? Can you explain it to me? Thanks!

More detail:

The value we get from QCT RIL is:

PREF_NET_TYPE_GSM_WCDMA_AUTO           = 3, /* GSM/WCDMA (auto mode, according to PRL) */

However, in Gaia, we map this value to the string: GSM preferred. So our partner is wondering why GSM/WCDMA auto mode can map to GSM preferred?

Hi Arthur, the wording seems not correct, could you help to check the Gaia side? Thank you.

On GSM devices, '2G preferred' is used for the type 'wcdma/gsm-auto`. On GSM & CDMA dual mode devices, 'GSM preferred' is used for the type. The string simply follows the same rule.

I was wondering does PREF_NET_TYPE_GSM_WCDMA_AUTO map to wcdma/gsm-auto?

What is PRL, gaia display this type as "gsm prefer", did that alright? What we shall display to user about this type?
Thanks a lot!

The wording here is strange too since a GSM device cannot camp on WCDMA, so why use '2G preferred'? why not just "2G Only"

Sorry, I meant GSM/WCDMA devices. If the device only supports the type 'gsm', it displays only the '2G only' option.

Now gecko maps PREF_NET_TYPE_GSM_WCDMA=0 to "wcdma/gsm" and PREF_NET_TYPE_GSM_WCDMA_AUTO=3 to 'wcdma/gsm-auto' [1].

And according to the comments in ril.h [2],
----
PREF_NET_TYPE_GSM_WCDMA                = 0, /* GSM/WCDMA (WCDMA preferred) */
..
PREF_NET_TYPE_GSM_WCDMA_AUTO           = 3, /* GSM/WCDMA (auto mode, according to PRL) */
----

Use wording "WCDMA Preferred" for "wcdma/gsm" and "Automatically" for "wcdma/gsm-auto" seems more correctly.

Thank you.

As we already have another patch dealing the string issue (bug 975265), I'll modify the strings as comment 9 suggested there.
