OK, so after installing the latest Candy5 v 0.9.0 these are my findings:
In Settings:
Home Button Wake Device: Broke
Back Button Wake Device: Broke
Your kernel doesn't support these features.
Cellular Networks, You forgot to theme it in Material Dark, so its still White.
After updating Google Play Services it breaks most Play Services Reliant Apps. Apps include but are not limited to:
Google Play Newsstand, Feedback Agent, Hangouts(Opening Any Conversation FCs it), XDA Premium, Reddit Sync(Adding your account FCs it).
Mobile Data, I'm in a pretty bad location to give any real insight into how unstable and broke it is as my single currently sucks regardless right now. (Holidays out of town, and in a ****ty little town in middle america, lol)
I can tell you with certainty that I have data running CM12(an unofficial build for the M4). And all gapps and apps that I mentioned above run flawlessly. So they are specific crashes to Candy5.
I will be honest, I didn't run v0.9.0 for much longer than a few hours. But these are my initial findings. After updating Google Play Services and reinstalling my apps(not the data for them) it was just too crashtastic so I just restored.
Material is really nice, definitely the version I'd like to run. Merry xmas and thanks for your efforts.
