Can't install or update apps

Try uploading the images again. I can't see them.

Thanks for any help

Have you tried installing a random free app to see if this issue also occurs?

Do you have any issues with other inline activities such as socials or just browsing the net in general?

I'm guessing Google's own support link didn't help?

Hi @Gazz0411, thanks for reaching out. 

Have you checked the below:

1. Do you have enough storage space to install more updates?

2. Do you have a stable internet connection during download?

3. Find the Play Store app on your device’s home or app screen > Touch and hold the Play Store app > Tap App info > More >  Uninstall updates.

I found a fix online. I need to disable play store app, then restart phone.
Enable playstore app again then install updates. Some apps install normally, some I have to perform the above. Weird

Golly it was hard to find. You appear to have apps not downloaded through Play Store. Read the following "From your smartphone or tablet running Android 4.0 or higher, go to Settings, scroll down to Security, and select Unknown sources. Selecting this option will allow you to install apps outside of the Google Play store. Depending on your device, you can also choose to be warned before installing harmful apps"
