iPhone 6 with SD Card Reader: Images blurred

[criticalmind]

Hello,

I am using the Apple Lightning to SD Card Reader a few months now and it's working fine except for one issue: After I import RAW images from my Canon DSLR, they are randomly blurred for a few minutes but sometimes a few hours or not at all, e.g. I can view, edit and share them immediately in full quality. This is very strange since it is not temporarily and completely independet from any circumstances. So I already tried to force close all apps, clear RAM (holding power/standby until slider appears, then hold home until slider disappears), hard reset and so on. It does also not matter if I'm on WiFi or charge my iPhone.

How big are the RAW file sizes?
I'm by no means a photographer but have used RAW images and the files sizes were in the 50Mb range!
Maybe they're too large to be rendered by the phone?

Importing raw files to a phone can cause problems,especially if importing more than 4-5 images,the iPhone 6 cache is too small,I think.
