Test the phone in safe mode for few hours or repair the phone with XC

Last time bt worked for 2 Days before turning itself off.
if i make a factory reset is like a repair with pcc or not?

Since it doesn't happen as often, it'll be hard to figure out what's causing this, you could repair the phone with XC but i don't really see another way to figure it out.

I will try with a factory reset, it is strange tough I have The same apps like on my old z5c and the old one was working without any problems.

if you are going to factory reset, you might want to repair the phone with XC instead

Without going through the pain of a factory reset, you may want to try first to reset your network settings. I'm not sure in English, but it should be something like this:

Settings/Backup & Restore/Reset Network Settings

That resets the WIFi/Data Connection (3G/LTE) and yes, the Bluetooth.

Yes is there, but this only delets the settings for those 3, when bt works I don't have connection problems with the smartwatch, Imo is a software /driver related issue with the bt.
I will try in the week-end when I have more time.

PS: what app may cause this tough?

[Michelasso]

Since once off the BT sometime doesn't turn on anymore I doubt it depends on any app. I imagine it's a bug in our version of Android. It just adds to the weak WiFi, the brightness going down to zero, the battery draining in some devices (mine the first days. Up to 6% per hour. Now it seems more normal). It's a new phone, some issues were expected. Hopefully we'll get an update soon.

[andysoft83_gmai]

Yes I also think is a bug, happening again just now and I tryed to do the test of BT from the xperia care menu and it fails, doesn't want to turn the BT ON-OFF .

As I said the only workarround is to restart the phone

So is a bug IMO, I will try to reset to factory in the weekend, maybe someone from SONY should investigate this issue for the future updates.
