Installing HD Games on HTC Desire SV,low memory
Short answer:
Thing is: you can't, obviously, as you don't have enough internal storage.
TL;DR
If your device is rooted, however, there are ways to work around this storage problem. You can fool your device by linking/mounting a partition on your SD card to be used as &quot;fake internal memory&quot;. But while this would work-around the underlying issue (not enough storage), the Playstore still would refuse to let you install those apps, as your &quot;official phone specs&quot; have not been changed. If you could get hold of the .apk, however, you might be able to side-load (manually install) it. Also, having root, you could manipulate the system file responsible for this (build.spec?), fooling the playstore into thinking your device would be a Desire X (or whatever you chose).
So you see there might be work-arounds, but they are not easy to apply. Without rooting your device (and thus most likely voiding your warranty if you're living outside the EU), it simply is impossible AFAIK.
