[Z5 Dual] Background data toggle missing with second SIM inactive?

erikm — Mon, 29 Aug 2016 22:13:19 GMT

So, this is a bit of an odd one. If I have both SIMs active, everything works as expected. If I disable SIM 2, then the following options both completely disappear:

settings-data usage-(...)-Restrict background data

settings-apps-(some app)-data usage-Restrict app background data

and as far as I can tell there's no way to change this setting if the second SIM is disabled.

I only recently noticed this issue, so not sure if it's a new bug in 253 or was introduced earlier. It definitely worked fine with a single SIM active in lollipop.

I believe that you can select just one Sim card for mobile phones data, put the second Sim and go in settings, dual Sim settings and check which Sim card is selected for mobile data.

Typo, "mobile data" not "mobile phones data".

Thanks YoGem, that's true, but is (afaict) unrelated. It doesn't matter which SIM is in use, and the general data settings work fine to switch between them. It's specifically the per-app background data that can't be changed unless both SIMs are enabled.

IE, I'm back at home and no longer need my "travel SIM" active for now - and suddenly I can't control per-app data usage.

(reenabling both SIMs temporarily seems to be OK as a workaround, but seems kind of klunky. I mainly posted this as an FYI in case anybody else runs into this, so they don't have to waste hours resetting things like I did before figuring out that deactivating the second SIM stole the settings option)

Oh wow, I must have misread your post and I must have been typing too fast as in reality I wanted to underline that such settings appears only with two sims inside the phone. But thank you for the possible bug report I was not aware that on lollipop was working fine!
