Xperia U - WiFi does not disconnect or switch off

[brookejohnson]

My wife and I have Xperia U phones that have in the last week stopped disconnecting from WiFi when out of range and we are unable to switch the WiFi off.  The only way to switch the WiFi off is to switch the phone off.

I was going to try and repair the phone using the Sony companion program, but the back up function does not work - keeps going to program not responding.  I am therefore not keen to try this out.

Are there any other solutions or is there a software update?

Android 4.04

Build no: 6.1.1.B.1.54

Thanks in advance.

The only recommand: give up and root your phone.

This is a known issue of Xperia U with ICS firmware, but Sony doesn't care it, and never try to fix it at all.

Thanks Hersey, I'll look into rooting the phone.

Try a soft reset. If it doesnt work, backup everything in laptop and do a factory reset.

Even factory reset doesn't really solve the problem.

The problem will happen again and again.

From what you have described, we would suggest that you try to perform a repair of the software using PC Companion. If the issue is related to a problem with your software this will be repaired and your handset will work as intended. To do this, you will need to install PC Companion from the Sony Xperia website. Please follow the steps below to do this:

1. Go to www.sonymobile.com
2. Select Support
3. Choose your handset from the drop down list
4. Select "View All Software Updates"
5. Download for PC
6. Check the requirements and then "Download PC Companion"

To then perform a repair on your handsets software, please follow the steps below:

1. Open PC Companion
2. Start 'Support Zone'
3. Select Phone Software Updates
4. At this point a pop up will appear on screen asking you to connect your handset while powered on, as the software repair needs the handset to be switched off please ignore these connection instructions and click on the blue link which states "Repair Phone”
5. Some on screen steps will now appear for you to follow. Please also connect the handset when you are prompted to do so.
6. When you are asked to connect the handset (still with the phone powered off) please press and hold the key stated on screen for 30 seconds before connecting the handset and keep it held down as you connect
7. The repair process should now begin.

Please ensure your handset is not connected to your PC when performing the above as you will be instructed to connect your handset once you have followed the above steps. Your handset must also remain powered off at all times.

Please note it may be the case that user data is lost during this upgrade. We therefore recommend backing up any data to your SIM card, Memory Stick, or PC before upgrading.

Please be aware that if an update to a later version of Android has become available for your Sony Ericsson Xperia handset the new version may be installed. If this is the case you may notice some differences in the functionality of your handset when updating. All information regarding these changes can be viewed on the following link. We would recommend reading through this before updating.

Ok, I accidentaly discovered how to turn of WiFi easily, without rooting. My battery is very weak, so I turned on battery power saver (settings->power management->extended standby mode). Thing is when you turn it on and the phone is in standby mode, android turns off all internet comunications (WiFi and data transfer). So if you want to turn off WiFi, just turn on "extended standby mode" then turn off WiFi and lock the phone. After that WiFi should be off. You may torn off "extended standby mode" after that.

Hope this helps for all of you
