My ultra dual turns off suddenly when I turn on wifi..

Hello sony xperia T2 Ultra Dual  users I hope someone could help me with this problem...

 

Whenever I turn on my wifi my phone suddenly hangs and turns off.. So I turn it on again and after sometime

let's say 20 to 30 minutes it turns off again.. This happens for 4 to 5 times repeatedly for a day then afterwards it runs smoothly.

My conclusion is that maybe my unit is in a period of adjustment and It's been barely 2 months since I bought the unit...

Kindly help me with this problem and thank you in advance....Slightly smiling Face

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

 

Sorry to hear about the issue you are experiencing. First of all I would suggest that you try to boot your phone into safe mode to see if the problem may be related to any 3rd party app that you have installed in your phone:

They don't want to replace my unit T2

Sir 

 

           Good day. I would like to report to you about my unit which I believe is a factory defect unit inasmuch as since I bought this one from day one problem arises. I just ignore them knowing that this is just simple. The main problem with this is that every time I open wifi my unit turns off after 3 to 5 minutes or sometimes immediately. I turn on and same thing happen all over again. I did what you tell me here to boot but problem remains at hand. I did a lot of BACK UP AND RESET for at least 10 times or more but to no avail. So last night I go to the store which I purchased this phone but they didn't replace my unit they only make back up and reset but nothing happens. This I believe is a factory defect unit.. I will reveal to you the store which I purchase my unit if you will find time to reply. Thanks and I just wanted to make good business with you guys that's all.
