Hello there,
In this post, you will find what to do if Port city would not load and all you can see is this black screen ( as you can see in the picture below):

What should I do in case I can see this black screen.
In most cases, this issue is caused by a limited amount of RAM. This means that the device does not hold enough short-term memory for the game to properly launch and run.
The minimum amount of RAM to run Port City is more than 3GB. If your device has 3GB or lower, unfortunately, the game will not launch properly and stay on this black screen. For this reason, it is important to check your RAM memory and do the basic troubleshooting to clear up your RAM.
Please note, that RAM memory and internal memory are not the same. RAM memory is an operational memory of a device when the device has more RAM memory it means that it can run the more complex applications smoothly without any issues. When you download and install an app, it gets stored on your permanent storage (that’s internal or external SD card). But all the live running processes run on RAM. Even if you close that particular app after a while, Android will not remove it from the RAM memory, so that you can recall it faster at any time you want.
How can I clear my RAM ?
As RAM is an operating memory it is used to store temporal data in order to run applications smoothly without any issues. In case you are not sure how to clear RAM memory on your device:
if you have an android device, please follow this guide
if you have an IOS device, please follow this guide
If RAM is not the issue, then it is always helpful to clear the cache of your device. Other than that, make sure that you close all background applications to allocate as much Performance to Port City as possible. Close anything that is unnecessary and running.
And the last step, please restart your device.
I have tried all steps but the issue is still persisting.
In a case that you have tried all steps and the issue is still persisting, please contact our support directly here with as much information as you can share with us:
- Please let us know about your device, which manufacturer and the exact type and operating system
- Is there any error message? Perhaps a pop-up? Is the game perhaps flashing before launching?
- Please send us a screenshot or a video about this issue. This would be greatly helpful for us.
We will do our best to help you to resolve this issue.
Thank you.
With ❤️ your Cm's Alz, Luc and Lenka
