Frequent Freezes of Wingray requiring Reboot
In Aug-Sept 2014, there was a discussion in the thread: [ROM][4.4.4] CyanogenMod 11.0 - Wingray Stingray Everest - bigPart, related to Frequent Freezing of Wingray requiring Reboots (see posts 595, 597, 599, 600, 611 and 615). I have been experiencing the same (or very similar) issues for several months. I have an MZ604 with Wingray and have been taking the monthly updates regularly since they have become available; I initially installed CyanogenMod about 7 months ago. I have been running with Xposed and Wakelock Terminator as described in http://forum.xda-developers.com/showthread.php?t=2697893.
The freezes almost always (with one exception) happen when the XOOM is sleeping; the exception was a crash that happened once while I was using the device, but it might be a different issue. Freezes were happening about once/day, but in the past few weeks had increased to almost every time I put the XOOM to sleep. The only way to recover from a Freeze is to completely reboot the device by holding both the power button and the Volume button simultaneously for several seconds. Freezes usually seemed to be accompanied with a significant battery reduction, so I suspect something was coming to life, using a lot of battery for a while and then killing the XOOM. My Battery Monitoring app would never keep data through one of these freezes, so it was useless in helping me understand what came to life, used the battery and then caused the crash.
For some reason, this week the XOOM has stayed alive for an entire battery cycle. I recharged it 4 or 5 days ago, and used it according to my usual pattern of 3 or 4 times per day for anywhere from 15 minutes to an hour each time. The battery went down by about 15-20% per day at a pretty consistent rate. I put it back on the charger this morning with 16% battery left. After the very frequent freezes prior to this week, I was very surprised to see it stay alive for a full 4-5 day period. For the rest of you who were experiencing these freezes/crashes, did your device start working without freezes this week too?
