[What to buy?] Dual Sim, Android 6 or 7, Mercedes SAP V2

[blueice_haller]

Hello,
I'm searching for a new/used Dual Sim Smartphone with Android 6 or 7 for Mercedes SAP V2.

What I read in this Forums is that Samsung Duos have problems with SIM 2.

I have enabled call forwarding to SIM 1 and would need SIM 2 only for Internet. Is this possible?



It would be nice if the battery is replaceable.

Until now I have a Galaxy S2 GT-i9100 but the space for apps is full.

In a second Car I have a Pioneer AVIC-F88DAB with HFP/AVRCP/A2DP.

Thank you in advance.

From my point of view the only dual SIM phones which work with rSAP are the many MediaTek phones.

MediaTeks with Android 7 all (?) seem to support rSAP with the stock firmware, the only small restriction is that you cannot choose which SIM card rSAP should use - it's always the first one. My app currently does not work with Android 7 MediaTeks!

MediaTeks before Android 7 are supported by my app or may even support rSAP with the stock firmware, although I didn't see many. In my app you can choose the SIM card for rSAP.

Samsung Duos and other dual SIM Qualcomm phones basically work with my app, but they usually lose connection to one or all SIM cards. Some can be restored with the Reconnect Plugin from this forum, but others may require a reboot each time after leaving the car

Z5 Dual Sim RSAP is working with first Sim card. As soon as Bluetooth is disconnected the card goes straigt back online. So primary no problem. But you need unlocked bootloader for root. No baseband manipulation necessary at the moment.

edit additional information: second sim card stays online while using rsap. But no HFP with the second sim card of course. So the mobile phone is ringing while a call is in on the second sim.

A dual SIM Qualcomm phone which supports rSAP without problems is rare, but it seems to exist

What would I need to do to get that working? I'm a returning user on mi mix 2 , after using native rsap on HTC M8 for 4 years. I've installed rsap install and main app, but there seems to be an issue.

If it does not work with my app as it is now, it will most probably never work. I simply don't know what I could do to fix the problems.
