Can someone help me in this.
I'm using 2 sim cards and 1st sim card is jio. If im using volte i can't make calls from 2nd sim card. I have to turn of VOLTE to make calls from other sim card. Is there a way to fix this?
No. I have same issue as yours. But I find a way out.
If you want a good battery life and better performance follow these steps.
1) backup your PE ROM (Only boot and system) using twrp (if you have otg then it's better).
2)Wipe boot,data,system,cache,dalvik cache,vendor using twrp.
3)Flash latest Unofficial lineage os build by Agustin Lorenzo.
4)Wipe boot,data,system,cache,dalvik cache except vendor partition.
5)Restore PE ROM (Created by first step).
6)Wipe Internal storage.
Once you boot in PE ROM. You will feel the difference in battery and heat issue.
If you feels heat then you should flash suncool mod.
