Hi, I have an Optus X start phone. Recently my sms' flicker when I open a conversation. One of which the whole screen flashed black n white briefly but really quickly- the contents of the conversation were still visible during this...
Hey there Kelbel,
What troubleshooting have you tried? e.g. turn the phone off/on, take the SIM card out, etc.
Has the phone been dropped/damaged?
Does it have the latest software installed?
