Scrolling behavior

[malnvenshorn]

I'm currently in the process to switch to open source apps on my phone. As a replacement for the adobe reader I found this app, but there is one thing which is terribly annoying in this otherwise great app: the scrolling behavior. There are two points:

1. It keeps scrolling even after you stopped to swipe. I know this feature makes sense to allow to scroll fast through a document, but this happens even if you are just scrolling a tiny bit.

2. Before you can scroll you have to single tap the screen, otherwise you can swipe but nothing will happen.

It would be great if this gets fixed :smiley:

I think the problem is that the scroll continues for much longer with less friction (2-3 seconds) than it does in normal android (1-2 seconds).

Switched to a newer phone running Android 7.1.2 and don't have the issues anymore. It seems it affects only old android versions. My old phone has Android 4.2.2

This is my problem as well and I'm on relatively new phone with Lineage OS 15 (~Android 8).

The scroll inertia is too high, it makes navigating very clumsy and easy to lose your position. Just as @malnvenshorn wrote, even if you swipe a little, it scrolls on an unexpectedly great amount. It's disproportionate. I read ebooks with the page size of a standard printed book and this happens both in portrait and landscape.

Please

• re-calibrate the default scrolling inertia,
• add an option to set scrolling inertia, maybe in the form of a slider (which would include 0, that is, disabling inertia completely).
