''insufficient space on the device'' – but my sd card has plenty space? I bought my Android phone a month ago (a Prestigio 3350 Duo) and installed maybe 5 apps on it, so according to the memory card I have almost 2 gb of free space, and 28 mb on internal storage. But when I try to install some apps it keeps showing off that message.

I don't know why, tried to clear cache (which helped a little) – but still I can't install an app of about 34 mb.

Can someone help me fix this problem? I know there're similar posts but I appreciate any help. Thanks :)
It has worked on Kitkat so may apply to older versions of Android


Settings > Storage > Phone Storage ( or could be Internal storage, wherever Google Play Services is) > apps > Google Play Services > Click Clear cache
(on the same page) Manage space > Clear all data > Manage search storage > clear now
press back button &lt;- twice and you will end up on Google Play Services - App info page > press Force stop 
Find Google Settings among applications or under Settings > Google settings > click on menu button on the page > Clear app data


Now you can launch Google play store and download desired application

Hopefully it works for you as well. Feedback will be appreciated.
