Just an update, sent in my ZF3 once again. Have been visiting the service centre 3 times and utilised 1 of my 2 home service. Having to undergo 3 times of factory reset. Today is the 3rd time of factory reset and next time collecting it back will be my 3rd time to restore my data. Each time I restore my data, it takes half a day.
Probably foldables are not ready to compete with rigid phones yet. Definitely not. Extremely delicate and susceptible to damages not caused by individuals.
If my ZF3 gets damaged after warranty through software update, I will switch back to using rigid phones again.
Basics like WiFi and OLED screen, they can't get it right. I am not talking about the inner screen. Even the outer screen can kena dead pixel. Never once my past rigid phones have experienced dead pixels before. Till today, my S3 screen is still going on fine, after 11 years alr. Z Fold 3 cover screen can't even last 1 year. 😒
