Samsung has given update for network issues in A50, I am using Airtel & Jio and faced issues only with Jio , please try this if your A50 network issue continue after update:
1. Switch OFF phone
2. Take out your SIM
3. Switch ON phone and reset Network settings
4. Switch OFF phone
5. Insert Your SIM
6. Press Volume up+ Power Key for wipe cache partition.
7. Reboot your Phone.
Enjoy and keep track of network issues again. I kept it under observation. keep in mind that Jio users are more and there network is overloaded .
