How can I tell if it would be safe?

I am running ViperOne 7.0.1 on an HTC One m7.

  • Why would you switch anyway? What are you trying to achieve?

  • Higher efficiency mostly.

On my Xperia M, running the latest nightly CM, it always causes trouble (every 10 seconds an app crashes), so I occasionally try it (Is it working yet? - No, well, I guess it's time to switch back), but I never use it - others say it's working fine for them. If you are able to switch to ART, I assume you are rooted and have a custom ROM installed, so you are also able to make a full backup from the recovery. You can try it, but make a Nandroid backup first, as it could screw up everything to the point you won't be able to switch back from inside Android. I'll say this again: switching to ART is NOT safe! Always do a full backup from the recovery before you try it!

On the first boot with ART, it's going to take a lot of time to compile everything, be patient. Good luck!


Of course it is. If your apps are crashing, try to reinstall your ROM and wipe your cache. Normally it shouldn't throw crashes
