I notice you are on KSA STC network.
Request for beta firmware Firmware Version:1.7.0 3.0.0 v60a2.0 Build 260204 Rel.41445n_Beta
This has multicell fixes (30+ nearby cells) for KSA network.
I have been running stable for 6 days without any issue using STC sim auto-band N40,N77,N78.
Manual band N77 still has disconnections bugs as below in Dammam area.
