[Sony Doesn't care this at all] WiFi Status locked, cannot change or turn off

[Heresy]

It looks like this is a general problem after ICS upgrade for Sony Xperia phone.

I didn't have this problem before even in worse firmware 6.1.1.B.1.10, but after using 6.1.1.B.1.54 two weeks, I have the problem now...

I can connect to AP after boot.

After use for a little time, the process "wpa_supplicant" start running, and never stop, just like the screenshot below (right-top corner).

When the process "wpa_supplicant" is running, I can neither turn off the WiFi, nor make any setting change about WiFi.

What I can do is reboot.

It looks that the WiFi status was been locked by this process.

According the information on the web (reference), this issue can be fixed after delete the file /data/misc/wifi/wpa_supplicant_bagscan.db. (rooted required)

But this file will automatic generated by wpa_supplicant, so the same problem may happens again.

Is there any way to fix this issue without rooted?

Your explanation may be relevant to problem I see.  Connection to wifi fails after a short while, phone will also not roam onto known networks.  The wifi app seems to 'freeze' and won't respond to the widget to turn on or off.  It may also be sucking a lot of battery power (wifi shows high use in battery meter).

Please escalate to have this fixed anyway you can!

Yes, the power consume is higher in this status.

As I know, not only Xperia U but also Xperia P and Xperia Go have the same issue.

The only way (without reset the phone) to slove it is root, and delete the file " /data/misc/wifi/wpa_supplicant_bagscan.db".

Hope Sony developers can fix this issue.
