These steps are for the Android app, the only one that exists: there's no iPhone app yet.
Step 1 - Close and relaunch the app
It's the simplest solution, the one to try first.
- Tap the recent apps button (square or three lines depending on your model).
- You see the list of apps open in the background.
- Swipe the Ktkarena app upward (or to the side) to close it completely.
- Relaunch the app from your home screen.
If that fixed the problem (the app is smooth again), great. Otherwise, move on to step 2.
Step 2 - Clear the cache
The cache is temporary data stored locally by the app to load faster. But when it gets corrupted or too big, it slows everything down. How to clear the cache explains in detail.
Quick version:
- Android Settings → Apps → Ktkarena → Storage.
- Tap "Clear cache" (NOT "Clear data" - that would log you out).
- Relaunch the app.
Step 3 - Update the app
If you're running an old version, known bugs may already be fixed in the latest version. The app isn't on Google Play and doesn't update itself: download the latest version of the beta from ktkarena.com/telecharger-beta and install it.
Step 4 - Restart the phone (and beyond)
If the first 3 steps got you nowhere, the problem may come from your phone itself (full memory, other apps consuming resources, stuck system processes).
Restart the phone: long-press the power button → "Restart".
After restarting, launch Ktkarena. If it's smooth, your phone was indeed the cause.
Still stuck? If the problem persists after all this, it's probably a specific bug. Report it: How to report a bug.
Include in your report:
- Phone model: for example, Samsung Galaxy A52.
- Android version: for example, Android 13.
- Ktkarena app version: shown at the bottom of Profile → Settings.
- Precise description: when the bug happens (at launch? after a few minutes? when you tap a specific button?).
- Screenshots or video if possible.
