Do you have a regular NANO SIM card or did you trimmed a regular SIM card?

It's probably a Third-party app, you could boot on safe mode for few hours or just repair your phone with PC Companion

Hi dandedoes,

Welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

There are a number of factors that can cause restarting, in many cases a SIM card or an SD card can be the culprit. I do suggest removing the SIM but also any SD card and try testing to see if the issue continues.

This can also be related to third party applications or apps that may have corrupt data. In such a case removing any new apps would help resolve such an issue.

Finally if none of the above works, then a software repair would be the best option to perform. See the instructions below on how this is done.

Before you start you have to download the PC Companion software from PC Companion
and install it on your PC.
2. Once installed on your PC, double-click the PC Companion icon on your desktop to start the update.
Note! For some models you will be prompted to do a backup prior to the update and then restore.
3. Install and open PC Companion then select Support Zone.
4. Phone Software Update.
5. Start.
6. Repair Phone
7. Continue
8. Accept data removal
9. Next
10. Wait for prepare
11. Select Phone
12. Follow the connection steps

I have a regular sim card.
The crashes has increased and now my apps suddenly stops. Guess I have to do the hard way and reboot like I have done once before. This didn't happen when I had a iPhone. Android was a bad choice...

We are sorry to hear you feel this way, however I would advise following Jake's advice.

@uli is there even a possibility to enter microsim or normall sim to this device?

I have had the same issue, except that mine has gotten so bad now that the phone won't even switch on, just constantly reboots. And if the phone miraculaously boots up, I just get error message after error message. Never had this when I had Samsung. Really wish I could return this phone. I have tried everything, hard reboot, safe mode, repair....... nothing works. I am ready to smash this thing into a million pieces!!!!!!

I understand you so well. I have now repaired the phone with Sony Bridge and for the 2nd time I have to find, download and reinstall a lot of apps, and configure several settings that are not included in the backup. It takes hours...
I have tried to sell the phone but 2nd hand prices are allready very low so I must say Sony Z3 is/was a very poor investment and I can only recommend other to buy iPhone...
