Sony Xperia Z5 Operating System crashing and lag - Flashing red LED

[lucassonyz5]

Hi All,

I have had some recent issues with my Xperia Z5. The operating system has super lag, and sometimes crashes while rebooting, along with the flashing red LED indicator. I have tried repairing the OS using the Xperia companion, as well as trying to load in safe mode - no luck. 

A video of the problem (os crash starts at around 40 seconds)

I have had no problems with the phone up to now - there wasnt any overheating, drops or any recetly installed apps which could have caused this.

Any advice appreicated, or has anyone else had this problem?

Thanks!

Hi @lucassonyz5,

I am very sorry to hear about this, let's see if we can help resolve this.

Have you tried removing the SIM card and SD card and booting it up to see if the issue continues?

Can you please test and let me know.

Thanks for your response - Still the same with SD and SIM removed.

I am sorry to hear that, this sounds although you may have a hardware related issue. 

I suggest that you contact Customer Care and see if you can get the device inspected by an authorized service agent.
