Sony Confirms Xperia 1 VII Defects: How to Check If Your Smartphone Is Affected

Sony has officially acknowledged hardware defects in a limited batch of its flagship Xperia 1 VII smartphones, impacting users across Europe and Asia. The confirmation follows weeks of user reports detailing sudden screen flickering, overheating during charging, and erratic touch responsiveness. While Sony assures the issue affects "a small fraction" of units sold between May and June 2025, the company urges all Xperia 1 VII owners to verify their device’s status immediately.

The Core Issues

According to Sony’s internal investigation, the defects stem from a faulty display component and voltage regulator in affected units. Users reported:

  • Persistent screen glitches (green lines, unresponsive zones)
  • Battery drain exceeding 40% in standby mode
  • Overheating during wireless charging, triggering safety shutdowns

Sony emphasized these flaws pose no safety risk but may worsen over time, potentially leading to permanent display failure.

How to Check Your Device

Owners can confirm if their Xperia 1 VII is part of the impacted batch via Sony’s official validation portal. The process requires your device’s IMEI number (found in Settings > About Phone) and takes under a minute:

  1. Visit Sony’s dedicated support page:
🔗 Sony Xperia 1 VII Defect Check Tool

  1. Enter your 15-digit IMEI.
  2. Review the status:

  • ✅ "No issues detected" → Your unit is safe.

  • ⚠️ "Service required" → Defect confirmed.

Sony’s portal also lists affected serial number ranges (e.g., models starting with XQ-DQ72 manufactured in Vietnam).

Next Steps for Affected Users

If your device is flagged:

  • Backup data immediately: Defects may cause sudden failure.
  • Request a free repair/replacement: Contact Sony Support or your retailer. Proof of purchase is required.
  • Loaner devices: Available in Germany, UK, and France while repairs are processed (2–3 weeks).

Sony has extended warranties for repaired units by 6 months. The company confirmed replacements will use revised components to prevent recurrence.

Why This Matters

This marks Sony’s first major hardware admission since 2021’s Xperia 5 III microphone defect. Industry analysts note the swift transparency may mitigate backlash, but advise users to act fast—unofficial repair attempts void eligibility.

"Proactive checks protect consumers. Delaying verification risks missing Sony’s 90-day defect claim window," warns Elara Hughes, hardware specialist at TechWatch.
