KOReader Pinch to Zoom and 1 finger pan settings for Android

cksachdev · 05-12-2025, 06:46 AM

I have installed koreader-android-arm64-v2025.04.apk on my One Plus 13. I am using KOReader to read pdf files and track the reading progress. I was looking for an alternative to Okular app on mobile phone.

I need help with following:
1. Two finger pinch to zoom settings for pdf
2. One finger panning once zoomed into pdf

I was able to find the following:
Gear icon on top menu -> Taps and gestures -> Gesture manager -> Spread and pinch -> Pinch -> Fixed layout documents(pdf, djvu, pics...) ->
There are following options with zoom word:
1. Zoom mode
2. Change zoom factor
3. Zoom to
4. Zoom factor

I experimented with changing the values, but couldn't get a desired result. I even tried ChatGPT and grok to see if these steps are captured anywhere. Could someone guide me with this settings.

While you can install KOReader on a regular phone or tablet it isn't a regular android app.

There's no "free zoom", there's no "free pan when zoomed".

The support for gestures and navigation we have is documented
in https://koreader.rocks/user_guide/

Don't assume something is there just because the rest of your android apps work that way.
