Cannot switch to 3g network automatically

My Xperia z2 cannot switch to 3g network automatically. I can switch manually very well. Is it normal? Other brand switch very well in my area.

Do you have the correct APN settings? how old is your SIM card? is it a micro SIM card or did you trimmed it ? Do you have stamina mode on?

That could be the issue, that the SIM card it's trimmed or it's simply acting up, try to get a brand new MICRO SIM card.

My sim card work on Nokia lumina 930. When I choose wcdma only it works fine but when choose media(proffered)/gsm cannot switch. My friend has this problem too with Xperia m2. This must be Xperia's issue.

Try as suggested above on safe mode, also trimming a SIM card could cause this, it doesn't hurt to get a brand new MICRO SIM card
