Are your photos set to save to the cloud, or directly on your device? If the photos are saved directly on your device these will be the full resolution for photos and you should be able to see them in the exact resolution at which you took them. If your photos are saving to the cloud, then that could explain the difference of when you first access the lower resolution, smaller file size photos. When you zoom in it accesses the actual image in the cloud and has to compensate to display the photo in the resolution you took it. This should explain, and solve your issue. Hope this helps!
Have you tried force stopping and clearing the cache and data for your camera app?
-Go to settings > apps > Camera > tap on force stop > then go to storage and tap on clear cache and data
Do you experience these symptoms if all camera modes?
Have you tried wiping the cache partition on your device?
The system cache partition stores temporary system data. It's supposed to allow the system to access apps more quickly and efficiently, but sometimes things get cluttered and outdated, so a periodic cache clearing can help make the system run more smoothly.
Give these steps a try:
Are you using the stock camera app when you are experiencing these symptoms?
Do you also experience these symptoms when using a third-party app that uses your camera?
Thank you for that information. I would recommend a software reflash on your device. You can take your device to your local UbreakIfix or ship your device in for service.
If you wish to ship your device in for service can you please provide me with the following information in a private message: http://bit.ly/2JH2rq2
