Most Android glitches come from three places: a misbehaving app, low storage, or risky web content. You can isolate problems quickly with a few simple checks.
Quick debugging flow
- Safe mode test - reboot to safe mode, then see if the issue disappears. If it does, remove the last few installed apps.
- Storage and cache - clear browser cache, remove unused downloads, and keep at least 15 percent free storage.
- Browser trouble - switch to a trusted browser and enable site protection to block malicious popups.
- Run a security scan - catch adware and trojans that hook into notifications or accessibility.
Tip: If the phone is hot or slow, check battery usage to spot apps running wild in the background.
