So i have Galaxy A12 SM-A127F which is Exynos variant. So it firstly didn't detected both SIMs at all. When i rebooted it recognized both SIMs but mobile network is not available, so i can't do anything with SIM cards. This same issue occurs on any TrebleDroid based GSI. I'm currently on Andy Yan's LineageOS TD-based and issue is still there, it was there too with your AOSP GSI. So there might be a fix for this in PHH settings or something but i want a guide to fix this cuz i don't want to mess up anything.
