Hi, You can try to use something we called PARTIAL_RESUME, for example from here: https://android.googlesource.com/kernel/msm/+log/android-msm-shamu-3.10-m-preview
The idea is if all registered wakeup sources callbacks that will be called after wakeup "agree" to go back to suspend then system will go to suspend without waking up userspace.
