I've been fiddling with the deblocking settings on the iOS app and it seems Low deblocking is not a good setting. Here are some snaps of the different settings as close to the same frame as I could get them.
Low Deblocking:
Medium Deblocking:
No Deblocking:
As you can clearly see in the background (between the trees) of the picture with the low deblocking setting on there is some weird stuff going on. The blurs, slightly different positions and lack/presence of the interface are all just because I'm really bad of taking snaps. Make what you will of these.
