My Nokia Lumia 640 camera isn’t working properly - the photos are blurry and I need to take a selfie.
Check there’s nothing blocking the lens. (This might sound simple but it happens!) Use a lint-free cloth to clean it. If your photos are still blurry, resort to IT Support 101 and turn your Nokia Lumia 640 off and on again.
Next, check for and install any software updates. If that doesn’t fix the issue, you should consider a factory reset (making sure you have all your content backed up first).
My touchscreen has stopped working - do I need an Nokia Lumia 640 screen replacement?
In order to diagnose this and understand if you need an Nokia Lumia 640 screen repair or replacement, we need to determine if the issue is software or hardware related. If it’s software, you may be able to take some action. First - is it an intermittent problem that only occurs when a certain app is in use? Try uninstalling that app.
As with other common issues, a hard reset is sometimes a good way to clear the phone and restore it to its former glory. Although you shouldn’t do this regularly, it can be a way to fix problems. Do a hard reset by holding down the power and home buttons for 30 seconds.
Still no response? It may be a problem with the hardware. If you’ve recently dropped your phone, this could be to blame even if there is no visible damage. It might be that a repair to the circuitry behind the screen, or an Nokia Lumia 640 replacement screen is necessary and iSmash will be able to help.
