Hold onto your Xperia 1 VII, owners! In news that’s never fun to hear but crucial to address, Sony has officially confirmed a manufacturing defect affecting some units of its cutting-edge Xperia 1 VII flagship smartphone. The good news? Sony is taking swift and decisive action, launching a free replacement program to ensure affected customers get a fully functional device.

The Xperia 1 VII, which made its grand debut on May 13, 2025, with a market release in early June, is a powerhouse known for its stunning 4K OLED display, advanced camera system, and premium build. It’s a device designed for creatives and tech enthusiasts, which makes this recent development all the more significant.
The Heart of the Matter: What Went Wrong?
According to Sony’s official statement, the culprit is a manufacturing issue with the motherboard, specifically a circuit board failure in a “small number” of Xperia 1 VII smartphones. This defect can lead to frustrating power-related problems, including unexpected shutdowns, random reboots, or worse, the phone simply failing to turn on altogether. No one wants their brand-new, top-tier device to suddenly go dark.
Sony states that as soon as the issue was identified, they immediately changed the manufacturing process to prevent further affected units from reaching consumers. Crucially, they’ve also confirmed that they have successfully identified every smartphone impacted by this particular manufacturing flaw.
Your Path to a New Xperia 1 VII: The Replacement Program
1. Starting July 21, 2025, Sony is rolling out its free replacement program. If you own an Xperia 1 VII, here’s what you need to do:
2. Find Your IMEI Number: This unique 15-digit code can be found by dialing *#06# on your phone’s dial pad or on the side of your phone’s packaging box.
3. Check Eligibility: Visit Sony’s dedicated IMEI checker tool on their official support website (a key resource is provided below for Sony UK). Simply enter your IMEI number to see if your device is part of the affected batch.
4. Initiate Replacement:
- If you purchased directly from the Sony Online Store: Sony states they will contact you directly. Alternatively, you can reach out to Sony support.
- If you purchased from another retailer: You’ll need to locate your nearest Sony Authorized Service Centre or contact Sony support for guidance.
5. Back Up Your Data: Before sending in your device for replacement, Sony strongly advises backing up all your important personal data. The replacement process will involve a device swap, and you’ll want to ensure your photos, contacts, and files are safe.
A Transparent Response: What This Means for Sony Users
While no manufacturer wants to announce a product defect, Sony’s proactive and transparent approach here is commendable. By quickly investigating the issue, identifying the root cause, updating their manufacturing, and launching a clear replacement program, they’re demonstrating a commitment to customer satisfaction. This swift action aims to restore trust and ensure that loyal Xperia users continue to enjoy the high-quality experience they expect from a flagship device.
This program ensures that those who invested in the Xperia 1 VII can do so with confidence, knowing that Sony stands behind its products and is ready to resolve issues when they arise.
