If changing the screen lock doesn't work (and it sounds like it might not help everyone) then don't worry, the upcoming update should still fix the black screen problem.

So, the update for Quell Memento has been approved on Amazon, so if you're affected by this it'd be great to know if this solves the problem.

The updates for Quell and Quell Reflect are being still held up until sometime next week, sorry.

Hi everyone

Ok we've worked out a cause of the black screen on ipad1. It looks like having the screen locked into landscape mode is an issue on iOS 5. Thanks Alex and Nancy for helping narrow this down.

We're preparing updates for this fix, but they can take a while to be approved on iOS, so in the meantime we recommend taking off the screen lock to run Quell. On iOS 5, you double tap the home button, and swipe left to see the screen lock icon. I hope this helps!

Hi again, Tom.

We're trying to fully understand your problem. We haven't heard of a problem in trying to purchase coins, and would appreciate more details of your issue, so we can try to diagnose where the problem might be. Which Quell game are you playing?

Apologies that we aren't able to respond immediately to all questions. We certainly do read them, and we address every problem we can recreate. We do our best to keep the community informed, even if it takes a few days.

Hi Tom,

We are sorry you have experienced this problem.

Can you tell us which game you are having the issue with? Also, was this problem noticed when you were buying coins, or buying 'Super Rewind' or 'Jewel Detector'?

Thanks!

The quell updates haven't been approved yet on Amazon, according to our devportal...

So, we're currently waiting for get hold of another ipad 1 this coming weekend. As we mentioned before, our own ipad 1 works okay which makes it really difficult to diagnose the problem. We're borrowing another one, which hopefully will have the black screen, and make it easier to fix.

So, the update should already be out on Google Play and iOS. The updates are still in review on Amazon, as there was a problem with the new Amazon Kindle Fires we had to fix before they would accept the update. But that fix is done, so we're just waiting on their approval which we expect in the next few days. Thanks.

Ok, we now have a selection of kind volunteers for iPad 1 testing, and are beginning to diagnose this issue. We'll report back when we have a fix, Thanks again for your patience!

Is anyone with an iPad 1 experiencing this issue, willing to test a new version(s)? If so get in touch at support@fallentreegames.com and we'll add you to our testflight users. Thanks!
