Thanks for getting back to us with the additional details, we certainly appreciate it!
I've taken a look at the listings you refer to and can see the issue with the enlarged images. It appears that the issue is not specifically with the images supersizing as intended from our templates, but the actual zoom feature on those images when using an Android device.
While there have been some minor changes on our end to the template layouts since you originally posted the listings the issue does occur with listings created from scratch as well as prior saved listings and appears to be specific to Android devices as you have noted. It is unclear what is causing this issue to occur, so we have gone ahead and created a work ticket for our engineers to investigate this issue and I will update this thread as soon as more information regarding it becomes available. I have also added your support case details to the ticket and we will update your support case as well once we have more information on this.
Thanks for taking the time to get us the further details and apologies for any inconvenience this may cause.
