Data connection issues

[Brat0811]

I just recently bought an XA ULTRA and had no issues during the first few days. I noticed several times that when the stamina mode turns on and after the batt is fully charged, i have issues connecting to mobile data. I turned off stamina mode but still there are times that i would need to reboot my fone before i can use mobile data. Please help. There are days that this happens twice in a day

does it give error when you connect to data after disabling stamina mode?

does this happen when you are on safe mode?

if this recurs continually, try to perform software repair using Xperia Companion

No error messages. Like today, I can't use mobile data unless I powercycle my fone. I was connected to my wifi at home the entire night, wasnt on stamina or safe mode at any point.
