Network Issue

[Nishant979]

Sometimes my phone doesn't search network automatically and needs to be restarted. Is this normal?

It could be that your Sim is faulty or dirty

I am using a new sim.

Try performing a system repair using PC Companion as this will often fix issues - This will factory reset your phone and erase all data so best to backup before you begin

Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)
Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the on screen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process

If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP

Is it a micro SIM card or did you trimmed a regular SIM card?

Micro sim

Follow Thommo's advice

I thought that lollipop update would solve the problem but it still exists.

If you think it is a hardware fault then you would need to either return your device to the place of purchase or contact Xperia care and have your device inspected http://www.sonymobile.com/global-en/support/contact-us/

I don't know whether it is hardware fault or software fault. Before Xperia Z2 I had Xperia Z and never faced such an issue with that.
