Black inside screen of Z4 Fold screen

[Donovan Cleophas]

 I bought my Samsung Z4 Fold 16 months ago and received excellent service from the device. Last week I was requested to update my phone , which I did. Subsequently the inside screen of my my phone just went black ever since, though I am able to use the smaller outside  screen. I have a colleague who has the same problem with her Z4 Fold. Has anyone else had similar experiences?  What can we do?

Mine just got back after two botched repair attempts, was supposedly the USB port ...

Try clearing the cache of the phone via > Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too. { Repair Apps may not be availableto the Samsung Galaxy s²⁴ Series of phone's. } 

If that does not work then back up and factory reset. 

Unfortunately if that fails then a Samsung Service Centre or Samsung Experience Store will need to provide support @Donovan Cleophas 

If I can be of any further help then please don't hesitate to ask.  😎
