Examination of Broken or Non-responsive Touch Screen Display Mobile Phones

Non-responsive touch screen or broken touch screen display panels in mobile phones which may be caused deliberately or accidentally are encountered by the Mobile Forensic Examiner. In such cases, extraction of data from mobile phones is extremely difficult as the mobile phones require a debugging process to synchronize with the tools for extraction. In routine practice, debugging settings are carried out on the touchscreen display panel of mobile phones. As such, extraction of data from mobile phones with non-responsive or broken touchscreen display panels is usually unsuccessful. An approach has been made to extract data from these types of mobile phones using the bootloader method in Cellebrite UFED Touch2. The methodology and results are presented in this paper. The objective of this study is to explore the possibility and probability of extraction of data from an aberrant environment of mobile phones in Digital Forensics.
