Thanks, I'm here as a user of N20 Ultra. I don't see cidmanager on mine -- Also @wr3cckl3ss1 is using a beta software, so that could be a difference.
As far as using Beta 2.....I've been able to disable cidmanager since AVDC.....since I'm stuck on rev. 2...can't go earlier to see but I'm pretty sure it's there.
The screenshots are from my device on the latest stable firmware, not beta. If you put in a SIM card and got a message to reboot, you definitely have cidmanager unless you uninstalled it manually via ADB.
To my knowledge....why not? Your only problem is finding a third IMEI....you can have that setup but I think two will work at the same time while one had to stay dormant. I could be completely wrong.though. I'm only basing this off the fact that my S908U has 2 IMEIs....one for sim and one for ESIM. Search around and find out. Because if it's possible....even i would do it.
Yes your right about that one. That's one thing i forgot to add in my post. But I can add that whatever it did, it gave me better service in parts i know for a fact, I had trouble or poor service in. Call performance also improved. The only thing left I would try is Data speeds. Im still clueless as to how it all works and what's enabled or disabled. But it's good enough for me. As far as RCS....i haveBe aware that you might not be getting any more signal strength. Various carriers handle displaying bars differently. Changing CSC and everything is gonna mess with that.
I'm curious though...
1. If you have NO cellular service with SIM1, can you use SIM2 "data", to send mms messages from the number associated with SIM1?
2. If you have NO cellular service with SIM1, can you make a wifi calling, call with the number associated with SIM 1, (using data from SIM 2)?
3. How does that work with RCS? I'm guessing RCS is still horribly messed up in this scenario.
I think I managed to separate the data from the voice/text by using adb.
FWIW there's pretty much no chance of tripping knox by flashing a signed fw and not unlocking the bootloader (not like you can anyways)
