ZFOLD8 Manager

Per-screen display size that switches when you fold or unfold, plus Flex mode for half-fold use.

How we got here: ZFOLD8 DPI Manager came first. Then we developed ZFOLD8 Flex. Then we decided to merge the two projects into one app, ZFOLD8 Manager, which is the one on Google Play now.

Cover screen home: display size per screen, switched as you fold

Overview

One phone, two screens, two sizes

Set one display size (DPI, also called screen zoom) for the cover screen and a different one for the inner screen. The app switches between them on its own when you fold or unfold the phone.

Flex mode is built in too: half-fold the phone and use the bottom half as a touchpad and keyboard while your app stays on top.

Optional Accessibility service (Flex touchpad and keyboard only)

The Flex touchpad and keyboard helper use an Accessibility service (“ZFOLD8 Manager touchpad & keyboard”). It is off by default and you turn it on yourself. It does not read, collect, store or share your screen content, typed text or personal data, and nothing leaves your device. DPI switching does not use it.

Good to know: Some apps reload when the display size changes, which is normal Android behavior.

Requirements

What you need

  • A Galaxy Z Fold8Built and tested for the Galaxy Z Fold8 only. A user has reported it working on the Fold7, but that isn't officially supported.
  • Root (recommended) or ShizukuChanging display size needs system-level access: a temporary soft root with DirtyFrag + KernelSU (easier), or Shizuku with no root. Steps are in Setup.
  • About 5 to 10 minutes, onceThe first setup takes a few minutes. After that, you just fold and unfold.
  • Unrestricted battery useRecommended, so automatic switching keeps running in the background.

Setup overview

Root or Shizuku

Pick one. The app walks you through each step on the phone; this is the general outline.

Setup guide (Root or Shizuku). An animated walkthrough of both setup methods, with sound. Animated demo, not a phone recording.

Option 1 · Recommended, easier

Root

  1. Install DirtyFrag from its latest GitHub release.
  2. Install KernelSU from its latest GitHub release.
  3. Run DirtyFrag.
  4. Open ZFOLD8 Manager and turn on Rooted mode.
  5. Allow root when KernelSU asks.

DirtyFrag is a temporary soft root. Nothing is flashed and the bootloader stays locked, and a restart fully removes root (if you turn on DirtyFrag's Autorun, it just runs again after each start). Tested on our own Galaxy Z Fold 8: Knox stays at 0x0, so the warranty flag isn't tripped.

Option 2 · No root

Shizuku

Shizuku is a separate app that lets other apps use system-level features, started through Android's Wireless debugging.

  1. Install the Shizuku app.
  2. Turn on Developer options on your phone.
  3. Turn on Wireless debugging and pair Shizuku over Wi-Fi.
  4. Start Shizuku, then grant access to ZFOLD8 Manager.

After a restart: without root, Shizuku has to be started again after each phone restart. That's how Shizuku works.

Tip: Can I hide the notification?

Yes. Hiding or silencing ZFOLD8 Manager's notification in Android settings only hides the icon, and auto-switching keeps working. Don't force-stop the app or set its battery use to Restricted; keep it on Unrestricted or Optimized. Once the notification is hidden, ZFOLD8 Manager works discreetly in the background, switching zoom automatically whenever you fold or unfold, with nothing to see or tap.
