i bought my new experia v from 8 month . from 2 month it begins restarting alone later it self power off i tried to change the battery and sim card and updated it to jelly bean 4.3 and the same problem knowing that battery is full but when i remove the sim card it works normally but it power off rarely , and when i connect it with charger it never power off , then when i insert sim card and remove charger it power off after 5 minutes or power off when it search for network then i cant power it on because it power off immediately now my xperia v with sony and they told me that they will replace the motherboard .
now i want to know is that a bug in that brand and it wont fix or what
