Z4 tablet stops at startup

[SBSB]

Hello Sony,
I have a Xperia Z4 tablet - 10 inches
It is almost new.
A big worry: it locks up regularly on ignition! Before I can enter the password.
I have to do at least 15-20 reboots / reset and use in the 20% battery + sometimes take 30 minutes to finally turn on the tablet in good conditions!
So, I leave the tablet at home since I never know if I will succeed in turning it on the first shot! I find it unfortunate for a product that is positioned in the top-of-the-range in 2017 (my old Chinese tablet at 45 euros never troubled me, bought 8 years ago ....)

Specifications:
I did a system restore, a reset .... this has not changed anything.
What should I do ?

Hi @SBSB,

Welcome to the community!

Sorry to hear about this 

When you say you have performed a reset, did you perform a factory data reset or have you performed a software repair using Xperia Companion?

Also, after the reset did you load all data including apps on straight away or did you test the tablet before loading data back on?

Let me know
