In the present world SMS is a cost effective communication. It has become a massive money-making industry as most of the active mobile users activity is messaging. SMS is treated as digital evidence in court of law at the time of trial. Most of the mobile forensic examiners are asked whether the SMS transmitted through mobile devices is fabricated or not. Messaging activity of active users on android mobile device is increasing but they are liable to do illegitimate activities. A technically sound user can modify an SMS in android mobile phone and profess it as genuine. In the first part of this work we ascertain the truth that it is feasible to falsify an SMS in android mobile phone. We breakdown the integrity of new generation mobile devices like android based phones by modifying the SMS (changing timestamps, text and finally sender identity). We need to defy this damage. The elucidation should be adequate to manufacturers, service providers, users and mobile forensic examiners. In the second part of our work we discuss mechanism and its implementation for preventing such attempts.
