Solar Explorer: can I download the old Lite version?
The new Unity version of Solar Explorer looks a lot better than the old Shiva version because it makes extensive use of GPU shaders. This is a major selling point of Unity. The drawback is that some shaders may not work as well on as many devices as the old version of Solar Explorer did. Usually the problem boils down to the GPU manufacturer not implementing the instructions correctly. It can also be caused by bugs in the graphics processor, or even bugs in Unity. While the shaders could (possibly) be modified to work on these devices, I’d need access to a physical example of every affected device. With over 5,000 different Android devices now in the wild, that’s an impossible task. The other problem is that I’m not a shader expert and I didn’t write the shaders in the first place… they were written by the Unity team, and the creators of some tools I used to build the app.
Installing the old version
If the new version of the app doesn’t work for you (or you just want the old version back) I’ve posted a download link to the last version of Solar Explorer Lite. To install it, you’ll first need to uninstall the new version of the app, then you’ll have to enable “unknown sources” on your device. Follow this guide. With unknown sources enabled, you can now install the app by downloading it on your device and clicking the APK file. After the app has been installed, make sure that you open Google Play and disable automatic updates for Solar Explorer Lite. If you don’t do this, then Google Play will just replace the old version with the new one again. Finally, don’t forget to turn off “unknown sources”.
