If you're having problems installing apps on your Android device, it could be due to one of these issues. Find out how to fix the problem below.
Let’s say you just found a great new game to while away the commute, or your friend just recommended a handy app that will make your life easier, but for some reason you're hitting a brick wall when you try to install it.
There are various things that could cause a problem when you try to install apps.
Check through the list to see if any of these answers solve the issue and allows you to install apps again.
1. Your Android phone doesn't have enough storage left
If you have a lot of other apps, videos or photos on your device, it could be using up most of your available memory. Check how much the app you want to install needs and whether you have enough space for it.
You can check this by going to Settings, then Storage. Check your phone has enough space for the app
2. Your phone’s cache could be causing the problem
Delete the Google Play Store’s cache and data on your Android device and try installing the app again. To delete the cache go to Settings, Apps, and All (swipe to the right to find this list). Then look for Google Play Store and tap on it. In that menu, scroll down and tap on Clear data. Just below that, you should see Clear cache, which you should also tap. Clearing the Play Store's cache could solve the problem
3. Your Android OS is too old and needs updating
Some apps will only work with later OS updates. Try updating your phone and then attempting to install the app again.
You can update your Android’s operating system by going to Settings, followed by About and then Software updates. There you should see the option to Check now. Tap on that and follow the instructions. Your phone's operating system may need an update
4. A factory reset of your phone may fix the problem
In some cases, resetting your Android device might solve the problem. Before you do that though, make sure everything important on your phone has been backed up so that you can recover it after the reset.
To reset your phone, go to Settings, Backup & reset, and then press Reset.
Try resetting your phone to solve the issue
5. You're using a screen dimming app
It’s quite common to use an app to adjust your screen’s brightness or the colour of its light. If you are using an app like this, it may be the reason you aren't able to install Android apps. If you're seeing the Install button but can’t click on it, this is most likely the problem you are having.
The reason for this is the way these screen dimming apps work. In order to adjust your screen’s output, the app actually adds an additional graphic element on top of your ordinary display. When your phone detects this, it disables the Install button.
This is a security measure designed to protect you from malicious software. If it didn't do this, malware could use an overlay to trick you into doing anything it wanted.
The good news for you, is that disabling the screen-dimming app should fix the problem.
Once you have installed the app you want, you can enable the screen- dimming app again, and enjoy your Android.

Ah yes, the lack of storage space, my constant problem...
