1.i strongly recommend you to factory data reset the mobile..... 2.if your a familiar with Odin tool do download firmware for your model and flash it manually and while flashing do choose cse odd not home cse in odin... its a perfect solution for all the problems you have mention above...trust me...... do try as i mentioned and see if it works....
