Hello Sony,
first of all I want to say that your album appbis preety good, however I found some area of improvement.
Basically, if you enlarge a picture and start to scroll to another to left or right side it is rather smooth and nice. Unfortunately, if you enlarge a picture, click on it once that submenu with options appears on it and then try to scroll your photos tobleft oe right side = the animation lags, you can see stuttering on pane to pane animations.
The other thing is that sometimes in normal gallery view (when you can see all the photos) scrolling is not as smooth as it should be. To clarify, I do not expect that all the pictures will appear just in a second as it is impossiblebdue to it has to read both internal memory and sd card, but even if it shows black thumbs (pictures not yet appear) scrolling down the gallery should be always smooth.
I bet Snapdragon 800 can handle it as well as thanks to your talented dev team you will improve it soon.
Please excuse any typos.
Guys please let me know if you encounter the same behaviour with animations when menu is turned on a picture.
It is weird, but I cannot attach a picture when I am writing this post from my Z1
Thank you.
