I noticed that sometimes when I try to make call from my call history or through the contact list, that the call refuses to dail. I will try it several times without any response until I restart my phone. This happens very often. I thought it's a virus attach and that have lead me to reset my phone about three times to factory settings yet the problem still persists.
Also I cannot use my Normal Facebook app. When ever I opens a Facebook app, it will take ages to load and thereby hanging my phone.
Please any solution to this?
