One week ago, November 13th, OnePlus started updating the OnePlus 2 phones with the latest OxygenOS update: 2.1.2. You can find details about it directly on the OnePlus forum:

The good thing, at least for me, is the CameraApp performance improvements; The really bad thing is the DualSim “Ask Every Time” problem. Changes in dual sim settings aren’t persisted at all, which means, every time you have to specify the SIM card you want to use for your call.
Dialer Workaround#
To fix this problem when you are making phone calls from the phone, you can install a different dialer and use internal settings for the dual sim, ignoring the system one. You can for example use “True Phone Dialer” which adds some interesting features for the dual Sim usage.
- SIM card selection by Contact or Contact Group
- Last used SIM for a contact (for example on a missing call you can automatically recall your contact with the SIM received the call)
- Dual SIM filter you can apply, for example, when you are linked to a bluetooth device
In the end, it’s an interesting application to use even without the native settings problem
This Workaround is NOT working for a (my) bluetooth car System (Renault/TomTom). If you make a call directly selecting a number from the InCar “dialer”, you bypass the “True Phone Dialer” and the SIM configuration is read into the global settings. So it’s a workaround that doesn’t work in any situation.
I’ll explain later how you can automatically switch the phone settings when you enter in your car. :D
Hopefully a new update will come out soon to fix and allow us to continue working correctly with the dual sim functionality.
