[ZT-f64ab781]

Model Name: ROG phone 2(8/128 indian version)
Firmware Version: WW_17.0240.2105.90_0
Rooted or not: not rooted
Frequency of Occurrence: every time
Hi Asus team,
I am using Airtel as my primary sim(slot1) and Jio as secondary.
1- When both sim cards are using 4g VoLTE network and mobile internet enabled on Airtel sim.
I very get low speed.
2- when Jio sim is disabled from network sim menu. Airtel mobile internet speed goes up instantly. In my case around 20-30 Mbps.
3- after enabling Jio sim again from menu, speed comes down by 50% or more and within few mins goes back to 1st case.
PFA screenshots.
Can anyone from Asus team check and confirm this?
Is it a hardware issue?
Can other ROG users check and confirm as well?

Thankyou for checking ARP_ASUS.

I tried multiple speed checks as requested. PFB results.
Speed test 1 - Airtel Data. Jio Disabled test 1- 29.71MBPS,test 2 - 17.84,test 3 - 17.24,test 4 - 20.73,test 5 - 17.19

Speed test 2 - Airtel Data. Jio Enabled test 1 -14.69, test 2 - 12.85mbps, test 3 - 7.31,test 4 - 3.60,test 5 - 1.92

Also device temperature increases by 5th test when both networks were enabled.
I'm guessing this has something to do with network selection algorithm in use,
But not sure.
