DPI Changer breaking Samsung stock apps on Galaxy Tab 3 7" T210

[Guest Andy From Ireland]

I am so pleased that I have upped the DPI to 250 using DPI Changer on my Samsung Galaxy Tab 3 7" T210 tablet, I can see the screen much better now and its a lot easier on my eyes - only thing is such a lot of the samsung stock apps are not working such as the camera, gallery, stock launcher, touch wiz (ive actually downloaded go launcher EX)  and loads of other samsung stock apps dont work with just a message of " unfortunately ** has stopped"

However if i put ppi back to 160 DPI then everything works again - what is it with the samsung stock apps, why do they crash with 250DPI and is there any workarounds apart from using alternative apps?  Thanks.
