Just did an update today, 5.1.1, and after the update it added an icon on my screen
its blue, looks like a blueprint of the phone, and its named "installer". When I click on it the screen just goes black (minus the status bar at the top) and it says "No applications available on memory card".
Whats this icon for, and how do I get rid of it???
Any help would be greatly appreciated!!!

that happened bc you had some apps on your SD card, after the update you will have to redownload the apps.
Thanks Uliwooly!
But I'm not sure which app was on my SD card that went missing 
Any way I can find out, as I'm unable to simply just uninstall that icon?
Sorry, I'm a bit lost now 😕
Long press just gives me the option to add to homescreen. If I swipe left it'll bring up the uninstall , show apps, filters, get apps list. I click uninstall, and theres no option to click a red x on the icon.
my bad, on the app drawer > swipe left to right > uninstall > select those apps
tried
wont let me uninstall it 
it greys itself out such as it would do with the camera, photos, album, playstore app.
I've no clue which app it could be
I must be an idiot when it comes to phones hah.
I'm in system - apps - on sd card, and there's the list of apps, so I click one and just click "move to sd card"?
Or should I just click the clear data button?
I'm oblivious to this type of stuff. 
trying to get an update here.
theres no apps on my sd card, everything is on the phone itself.
still cant figure out how to delete that installer icon, and I've been searching online as to what to do and I cant seem to find a solution...
