Question 5
a) List two causes of corrupt software problems in mobile phones.
b) State two messages on the screen of a phone with corrupt software.
c) State two ways for solving corrupt software problems.
Most of the candidates could not list two causes of corrupt software problems in mobile phone, neither could they state messages displayed on the screen of a phone with corrupt software problem.
