Bottom screen heat up

[cry0go00]

It's normal if you start using your phone or open the phone screen, the bottom screen will start to heat?
I just notice on my Xperia xz1, but if I stop using it, it will start to cool down.

Hi @cry0go00 

Since in that area you have the main cellular antenna area, are you experience any bad signal coverage? Or does it happen on a specific condition?

Hello @Hungvip2001

Did you try a software repair using Xperia Companion?

[Hungvip2001]

Wifi connection is bad, so I try 3G and it is a good signal.

Both heat the phone very fast, but just the bottom screen, Navi bar and bottom speaker.

Updated to lastest firmware.

I can't use companion because I unlocked bootloader, but this issue existed from the first day I buy the phone

@Hungvip2001 Hi

If you have try that, and updated your device, or you try to repair your software or try to explain the situation to your local support team! Even though you have unlocked the bootloader.

Hi @Leony

Have you tried the suggestion that i gave above?

[leoy76]

Hi,

yes I did, but the problem persist.

Now I requested a substitution to amazan, I hope the new phone will not present the problem.
