Thanks for the information brother because my phone is functioning perfectly now and I'm extremely happy. The steps in points (A) regarding cache partition solved half of my problem and below catch partition i found 'app repair' option so I did that which solve my remaining problem. After that I updated all my applications and uninstall one which have some issues as you said in point (B). Hopefully now my phone is working smoothly. Once again a big thank you and yes ,will certainly accept it as solution !!!😇
