Hi When your Galaxy A16 keeps going back to the home screen while using apps, it usually means One UI or an app is crashing, or something is interfering with system memory. Let’s go step-by-step to fix this:
---
🧩 1. Check for System & App Updates
1. Go to Settings → Software update → Download and install.
2. Go to Galaxy Store → Menu → Updates → Update all.
3. Also open Play Store → Manage apps & device → Update all.
> Sometimes Samsung pushes small patches that fix app-closing issues.

🔄 2. Clear System Cache
This refreshes system files without deleting your data:
1. Turn off your phone.
2. Press and hold Volume Up + Power until you see the Samsung logo, then release.
3. Use the Volume buttons to navigate → choose Wipe cache partition → confirm with Power.
4. Select Reboot system now.

🧰 3. Repair Apps (via Recovery Mode)
If step 2 doesn’t help:
1. Boot into the same recovery menu (Volume Up + Power).
2. Select Repair apps (usually at the bottom).
3. Wait for the phone to reboot.
> This re-optimizes all apps and often stops random app crashes.

🧼 4. Check Battery Optimization
Sometimes Android closes apps too aggressively.
Go to Settings → Battery and device care → Battery → Background usage limits
Turn off “Put unused apps to sleep.”
Tap Sleeping apps and remove the ones you want to keep active.

🔍 5. Safe Mode Test
This checks if a third-party app is causing it:
1. Hold the Power button, then long-press Power off → Tap Safe Mode.
2. Use the phone for a few minutes.
If the problem stops, a downloaded app is the cause.
Reboot normally and start uninstalling recent or suspicious apps one by one (especially cleaners, launchers, or battery savers).

🧽 6. Clear System UI and Launcher Data
1. Go to Settings → Apps → One UI Home
2. Tap Storage → Clear cache (don’t clear data yet).
3. Also do the same for System UI (if listed).
If still not working, you can Clear Data for One UI Home (it’ll just reset your home screen layout).
---
🧯 7. Factory Reset (Last Option)
If none of the above works:
1. Backup your data via Smart Switch or Samsung Cloud.
2. Go to Settings → General management → Reset → Factory data reset.
