- First, my primary device at the time, the Sony Z3 Compact. Not only did the screen crack, but the digitiser failed too, I couldn't even unlock the device. I moved to an old backup device, the Sony Z1 Compact.
- A day later, I cracked the screen on the Z1 Compact! I was clearing out some dirt from the earpiece with the pointed end of a safety pin. Innocuous! Same result, cracked screen and the digitiser failed so I was unable to unlock the device.
Unlucky? Careless? Either way, the devices had not been subject to any unusual conditions, heat or cold. It's not really surprising that they failed in the same way given they were made by the same manufacturer, but plenty of phone screens crack and leave the digitiser operational, giving you a 'grace period' to get a replacement sorted! I must also add that these phones between them have had around 3 years of daily use, but the digitisers still seem fragile in my opinion.
This all happened 4 days after I was a guest on the Phones Show Chat podcast, where I was complementing the Sony Compact range in general, and confirming I was really looking forward to the Z5 Compact! Timing...
Following a successful Nexus 4 screen replacement last year, and yet-to-be-blogged iPhone 5 screen replacement a few months later, I confidently ordered replacement parts to fix both phones. Here's the Z1 Compact screen replacement.
WARNING: This is not a "how to", should not be mistaken for step-by-step guide, and contains very mediocre photography...
A broken screen and knackered digitiser too:
The screen and digitiser came as a single unit, but did not include the adhesive, so I ended up ordering this separately which set me back a few days:
Removal of the old broken screen is as simple as applying heat (YouTube videos will say use a heat gun, I find a hair dryer works fine), then lifting the screen with plastic tools. The one supplied here looks suspiciously like a guitar plectrum:
Here you can see Sony's factory-fitted screen protector getting in the way; peel this off then get on with removing the actual screen:
Here you can see the adhesive clinging on as the screen is lifted from the chassis:
Having disconnected it, the old screen lies next to the chassis. It's best to remove and clean up as much of the old adhesive as possible, to ensure maximum effectiveness of the new assembly:
Attaching the new screen and doing a power-on and touch test before is always a good idea before fully sealing it to the phone...success:
Having peeled away the film on one side of the adhesive, you can see where it will line-up inside the chassis, around the front-facing camera and earpiece:
Adhesive applied to the chassis, now peel off the blue film, then connect and place the new screen into the chassis:
All done! There is one more step advised, which is to either place the device in a clamp, or between heavy books, to ensure the adhesive gets to work properly. I did the latter, overnight, and it has worked perfectly:
Here's the old beaten-up back cover:
Same as the front of the device, heat up and pry the back cover from the chassis, then remove all the old adhesive and clean up the surfaces:
Then place the adhesive and the back cover onto the chassis. As with the front screen, some pressure from a clamp or heavy books for a few hours helps the adhesive get to work properly:
The total cost was £32, and 50 minutes of my own time to do the whole job, including the screen and the back cover. It was nowhere near as complex at the Nexus 4 or iPhone screen replacements; no screws, no removing components to gain access to remove the screen or back cover, just heating up to loosen old adhesive, and put new adhesive and new parts onto the chassis!
