8 Sony Xperia Z3 problems, and how to deal with them

Sony Xperia Z3
Has your Xperia Z3 broken down on you? Is it refusing to perform as it should? If you’re wondering how to repair your Sony smartphone, and hoping to avoid having to send it in for a service, then you’re in the right place. We’ve got a list of the most commonly reported Xperia Z3 problems right here, along with suggestions on how to fix them, or work around them.

Unresponsive screen, texts won’t send, overheating

Glitch: Touchscreen unresponsive or glitchy

A lot of people have had trouble with the touchscreen refusing to register touches, being laggy when typing, fast scrolling, or randomly highlighting text and zooming. This seems to be an issue that has cropped up on other Xperia phones as well.


  • A restart of the phone will usually resolve the glitch, at least temporarily.
  • If your issue is specifically with the keyboard, you might find that another keyboard works better. Try downloading Swiftkey or the Google Keyboard.

Potential solutions:

  • Go to Settings > Display, turn Tap to wake up off, and see if that helps.
  • You should also make sure that Glove mode isn’t on in Settings > Display.
  • Go to Settings > Language & input > Xperia keyboard, and try turning Gesture input off. If it is already off, then turn it on and then off again, just to make sure.
  • You could also take a look in Settings > Accessibility > Touch & hold delay to try changing it to Medium or Long.
  • Try installing Sony’s PC Companion software, and choose Support zone > Phone/tablet software update > Repair my phone/tablet, and then follow the instructions carefully.
  • You could try a factory reset. Back up your precious stuff, and then head to Settings > Backup & reset > Factory data reset, and give it a try.
  • There’s a chance that you have hardware fault, but you’d expect the flaw to be pretty consistent if that was the case. Try downloading Yet Another MultiTouch Test, and see what’s happening. If nothing else has worked, you may have to contact your retailer, carrier, or Sony about a replacement.

Problem: Texts won’t send

A few people have run into an issue where they can’t send text messages from their Xperia Z3 handset.


  • Try switching Airplane mode on and off again.
  • This may be caused by VoLTE, if you have the option. Go to Settings > Call, and make sure that Enable VoLTE is not checked.
  • You could also try turning Wi-Fi calling off in Settings > More.
  • Try going to Settings > Date & time, and make sure that Automatic date & time and Automatic time zone are not checked.

Potential solutions:

  • The first thing to check is your APN settings. Go to Settings > More > Mobile networks > Access Point Names, and make sure they are correct. You can find the right settings on your carrier’s website.
  • Try using a different SIM card, just to make sure that’s not the issue.
  • You could install Sony’s PC Companion software, and choose Support zone > Phone/tablet software update > Repair my phone/tablet.
  • If you’re still having issues then it’s time to contact your carrier.

Issue: Overheating

Quite a few Xperia Z3 owners are suffering with overheating issues. This is most common when using the camera, but it might happen when you play graphically intensive games, or when you’re downloading, charging, and using the phone all at the same time. It was a major issue on the Xperia Z2 when trying to record 4K footage, and it seems that Sony hasn’t entirely resolved it with the Z3.


  • Remove the case, if you’re using one, to allow the heat to dissipate. Do not dunk it in cold water, because there’s a risk it will crack.
  • Try to avoid using the phone while it is charging or in very hot environments, if you can.

Potential solutions:

  • There’s always a chance that you have a software issue, or a rogue app is causing problems. Try wiping the cache partition first. Hold down Volume up and Power together, while the phone is on, and wait for the screen to shut off. You should feel the device vibrate three times, and you can release the keys. Press and hold Power to turn it back on, and see if the problem persists.
  • Your last resort is to try a factory reset, or repair using Sony’s PC Companion software.
