I know it's a bit OT but I'd like to point this out anyway...
Personally used RN5 Pro for 4+ years until last month, great device with super good custom ROM support but unfortunately had to exchange the device with my Dad's Asus Zenfone Max Pro M1 (same CPU/RAM/Storage) only due to no VoWiFi support on Jio SIM. It's a must for me at home since there's little to no network coverage inside.
Zenfone supports wifi calling on all major operators while RN5 Pro only on airtel which my dad uses so it's a win for me and no-loss for my dad
