Are Sony Xperia Z phones cracking by themselves?

Cracked smartphone

Phone screens cracking by themselves? Sounds spooky, but that’s what we’ve heard from some Sony Xperia Z customers. The question is whether Sony’s fixing phones for free under warranty.

Smartphones aren’t invincible, even with developments like the scratch-resistant ‘Gorilla Glass’. A drop from your pocket can result in a broken phone, and an unhappy owner. But what if the cracks weren’t caused by your clumsiness? What if they mysteriously appeared?

That’s what some Sony Xperia Z customers have been experiencing. This is a phone that’s meant to be tougher than your average smartphone, with the added benefit of being waterproof. And yet there are reports of hairline cracks appearing as if by magic, without any force being applied. One theory goes that these small cracks are due to the phone overheating, which is then making the phone unusable.

The cracks are beginning to show

In a lively thread on Sony’s forums, Monsoon comments about his Xperia Z:

‘I pulled my phone out my pocket at the weekend and there were two hairline cracks running diagonally down the screen rendering the top 2/3 of the screen useless.’

Scoops99 says they’ve had the same problem:

‘[I] had the phone in my pocket like I have done for the last four months and found the phone did not work, I cannot unlock the phone or enter the PIN. On further investigation, after removing the screen protector, I noticed two hairline cracks coming from the right-hand side of the screen. The phone has never been dropped or bashed.’

When these customers get in touch with Sony, some have been quoted more than £200 for a repair. One of Social Student’s writers said:

‘I was told that there was a £200 fixing fee as the phone was ‘BER’ (Beyond Economic Repair) and was not covered under the standard warranty. If I didn’t want to accept the repair bill, I would be charged £15 for them to send the damaged phone back to me!’

Replacements under warranty

However, some customers appear to be having some luck with Sony. Some forums and unofficial blogs claim that Sony will replace phones under warranty if there’s only a ‘single crack in the display’, and that there’s no evidence of abuse. However, this is not something we can confirm, as we’ve also read comments from customers who say they’ve had difficulty getting a replacement, like Bettyboo on Sony’s forum:

‘I had the same issue within a day of use, screen cracked by itself with a hairline crack and stopped responding. I sent to Sony UK, got a quote back for over £240 and they claimed it was down to physical damage not a manufacturing defect. […] I literally begged and told him it’s not accidental damage but a problem with their screens. He never admitted there was, but promised as a good will gesture they will on this one occasion replace it.’

So, do you own a Sony Xperia phone? Has a crack appeared as if from nowhere? How has your experience been with Sony’s customer service team?

We reached out to Sony for a comment – a spokesperson told us:

‘We are sorry to hear that some customers are reporting cracks in the screens of their Xperia Z smartphones.

‘We build all our devices to a high quality standard, and submit them to rigorous testing procedures. In the case of Xperia Z this has included evaluation against our Global Reliability specifications. Tests carried out include free-fall, bend, pressure, heat and other simulations to reflect the different uses of our products in the field.

‘Xperia Z’s frame is made from glass fibre polyamide, the same tough material that is used as a metal substitute in cars. The glass used is tempered, and has a shatter-proof coating, making it much stronger than regular glass. This along with its proven water and dust-resistance contributes significantly to the durability of Xperia Z.

‘However, damage can occur to any smartphone screen for a variety of reasons. These include, but are not limited to, a screen suffering a sharp knock, exceptional localised pressure, or simply from being dropped.

‘Assessment within our product returns process demonstrates that only a small proportion of reported cases cannot be obviously attributed to an identifiable cause such as those listed above. Our quality control monitors confirm that the return rate of Xperia Z smartphones due to a cracked screen are at a very low level and, we believe, well within norms for the high-tech consumer electronics industry.

‘In cases where no identifiable cause can be found, we have replaced the customer’s phone quickly and without charge.

‘When a customer has an issue with their Xperia smartphone we urge them to call our local customer service centres – the UK number to reach them is 03705 237237.

‘Our customer care and repair centre agents are required to handle all enquiries on a case-by-case basis and try to determine the most likely cause of damage. We will generally repair or replace the device if there are no obvious signs of customer damage.’

‘Once again, we’re sorry to hear that some consumers are unhappy with their devices, or the service they receive from Sony. If any customer has any concerns we urge them to call our customer service centre on 03705 237237 (8am – 8pm Mon – Fri, 9am – 5pm Sat). We commit to assess every complaint on a case by case basis to reach a fair resolution as swiftly as possible.’


Any other to way to still use the crack screen?? Maybe we can do something…put something conducted to electric such as alluminium foil in the back of lcd so the lcd maybe crack but it still connected to the power by the foil..can we do this method or not?


Sorry Nafees – the use of your screen to make changes to its input is usually capacitively done once the screen is broken you lose the connected total capacitance,s ability to influence it.

I have a sony Xperia z5 4 months old kept in a leather case under 2 year contract with vodafone. Last week noticed a hairline crack 1cm down from the top of the phone going across whole screen. Not dropped or damaged. Sent the phone it to repair centre through vodafone store. Store manager included in his notes to the repair centre there was no visible evidence of damage by me. Called today by third party UTL advising the phone was cracked and out of warranty and will not be repaired unless i pay a repair fee. I have been signposted back to vodafone to challenge their decission and as ever am receiving ridiculously poor customer service from vodaphones technical department.


K11OXA – I see vodaphone for the fourth year running is the worst offender for customer complaints ,according to OFCOM . Your Sony Xperia Z5 is another one on the long list of complaints of screen cracking , you are certainly not alone in the world in this models respect . I wish you luck in any battle you might have as I take it being 4 months old and told “out of warranty ” means = You broke it ! This is the standard speech from Sony probably delivered to Vodaphone by them . I think now Sony has shut its factory in China down or is in the process of doing so and set up in another far-east country , from what I recollect Thailand and as I have said many times on this Convo much as Sony TRY to make out their phones glass is made by CORNING –“Gorilla Glass ” (trademark ) Corning make no such statement but dont show Sony on their website of companies it sells its glass to . Not only that they have a disclaimer saying that any company NOT listed is not now allowed to say it uses their product . I now see Sony has taken off the offending advert.

I just hope their new Thailand factory is better than the Chinese one they closed down and they start buying Corning Glass . This “excuse ” “accidental damage ” is saving Sony a fortune worldwide .

my Experia Z5 which I purchased on 18 March 2016 got a hairline crack on the screen on 30th April 2016 while my phone was in my jumper pocket I was unable use the phone after this, I took the phone into o2 where I purchased it from to be told it would cost me £200 or more as not covered by the warranty it fell into the accidental damage category ( was not my fault!!) I have emailed Sony as yet to receive a response think will be a long time coming!! Needless to say I’m not happy!!


kmh- I wish you luck you will need it but there are several UK companies that will repair it for £100 or so. I just hope their new Thailand factory is better than the Chinese one they closed down and they start buying Corning Glass . This “excuse ” “accidental damage ” is saving Sony a fortune worldwide .


For those that say – Wiki has Sony advertised as using Corning BUT visit the OFFICIAL Corning Gorilla Glass website and you will NOT find Sony listed even if you click on the extended info page , not only that Corning has a prominent disclaimer –if it aint here it is not supplied by Corning (abbreviated ) .

Update on my issue going back to 2014 vodafone have now placed my account in the hands of a debt agency and are refusing to take me to court “so i will have to take them to court if thats my wish” so how can i fund a fight against this monster?

So many people logging the same issues and tv programs addressing the same complaint the supply of goods act and breach of contract all going against them and still its down to the little guy consumer to take out a summons against them? REALLY!!!!


Richard you are up against a world conglomerate that is massive and takes in many countries round the globe although US firms fought back in a take-over bid and won, its in most countries running their mobile services . It admitted that it is “wired in” to ours and overseas security services -willingly – and all your meta data is collected and surveillance is even more open than MS . What you need is a large group of like minded Vodaphone users who have been badly treated to start a class action against Vodaphone and going by the number of complaints -Vodaphone being the most complained about ,at least in the UK , you should get some help legally maybe even a lawyer/ QC to act on your behalf for maybe costs.
