Symptoms
- Crashes or freezes continue on a freshly reset phone with no apps added
- Problems appear even in safe mode before installing anything
- Random restarts happen within minutes of a clean setup
- Same symptoms as before the reset, unchanged
Likely causes
- CommonFailing storage chip causing system-level instabilityStorage hardware issues can cause crashes regardless of what software is installed.
- CommonBattery issue causing power delivery problemsAn unstable power supply from a failing battery can cause crashes and restarts independent of software.
- PossibleOverheating component causing thermal shutdowns or instabilityA failing component generating excess heat can destabilize the whole system.
- PossibleMotherboard or logic board faultPhysical damage or component failure on the main board can cause persistent, unresolvable crashes.
- Less commonWater or liquid damage from the past causing gradual corrosion issuesPrior liquid exposure can cause problems that worsen over time even without obvious initial symptoms.
What to do
- Confirm the reset was truly complete and no apps have been reinstalled yet.
- Use the phone minimally in this fresh state and note how quickly problems reappear.
- Check if the phone feels unusually hot even during light or no use.
- Check battery health in settings for signs of significant degradation.
- Note any history of drops, liquid exposure, or physical damage that might correlate with when problems started.
- If problems persist on a truly clean reset, treat this as a hardware issue rather than continuing software troubleshooting.
- Back up any accessible data immediately in case the phone becomes unusable.
When to call a pro
Persistent crashes on a fresh factory reset almost always mean a hardware fault; take the phone to a qualified repair shop for a full hardware diagnostic.
