when we connect charger its lock screen clock is crashed and not working any key in 7 to 8 sec and then it on but not working fast charging. Please solve this problem and inform me.
Hi @nk3927, I am very sorry to hear that. 
If I understood you correctly, the whole phone freezes as you connect a charger? Also, are you using the original charger which came with your device?
If it still persists even after performing a software repair using Xperia Companion, then I recommend that you get in touch with your Local support in order to have it sent to an authorized service center.
In that case I recommend getting in touch with your Local support so that you can be assisted in sending in your device to an authorized service center.
