I am another victim of this problem.
I bought a new 5Gs Plus and slot1 does not recognize my SIM1. If i put SIM1 in slot2, it working. I have other SIM and it working fine in slot1 but my SIM does not.
I update my phone to the last version, but i think the problem is hardware.
I cant put paper because the warranty will be forfeited.
So here is too many SIM errors in the world, if some part is defective (if the slots are sloppy), why Lenovo have not fixed it yet? 1 year later!

I have received system update Android 8.0 in mobile , after some time my both sim card not detected.
after some time (4 hours) sim detected. It happens 2 to 3 time.
There is not a problem in SIM, It happens after update system software.
