USB Charging Port Malfunctioning

My USB charging port is acting up recently. It's very finicky.

Just last few days, I cannot get "Fast Charging". It just shows regular cable charging.

I've tried:
(1) Firmware Factory Reset
(2) Tried different USB cable aside from the OEM
(3) Tried different wall adapter aside from the OEM
(4) Making sure USB cable is pushed all the way in.
(5) Tried using different wall outlets

I have had this phone for a little over a month.

Anyone else having this charging issue, and found a resolution?

Rear camera-hardware detected, yet black image. Camera "bus" malfunctioning?

Hi

Half a year ago my girlfriend accidentally gave my Z3 Compact a rollercoaster ride in our washing machine (full tour). The screen broke, but it could turn on and everything looked fine (gave no errors) when connecting to HDMI.

Yesterday I received a replacement LCD, which gave it a new life. It seems that everything works except for the rear camera. When opening any camera-app, the HUD is visible, but image is black, and no error. If i switch to front camera, which works, and back to the rear camera, it shows a freezed image of the last image from the front camera.

I checked some debug-apps to see if it detects the camera-module, and it does. If it's connected, alle the specs of the camera is listed, and if disconnected, the module is not listed.

I then got a broken Z3 Compact from a friend, and I tested both rear camera modules in both phones. The modules are working in his phone, both doing the same black screen in mine.

I tried hard reset, PC Companion-repair, updates, clearing camera cache etc., but with no luck.

Do you have any suggestion to how I can fix this?
Do you know where on the motherboard I could look for dirt in relation to some "rear camera bus/chip"?

Thank you for any help!
