|My Motorola XT912 after |
Cyanogen 10.2 Upgrade
Performance Was HorribleAfter a few recent updates in the fall the phone started to become unreliable and would freeze up when doing the most mundane tasks. It would sometimes take my favorite navigation app Waze (http://blog.trebacz.com/2012/08/android-apps-for-your-road-trip.html) 15 minutes to acquire a GPS lock. Foursquare checkins would also take 5 minutes.The battery would drain in a couple hours when traveling -or just out of the blue on some days at work.
I tried rooting the phone. Eliminating Verizon bloat apps that I really didn't use and shutting off some location services. All of this would work for a week, but come back in the form of freezes, lockups and bad performance after a couple days.
Permanently Improving XT912 Stability and Battery Performance
At this point I decided I was going for broke with the phone I liked or buy a new Samsung Galaxy 5S. I didn't need Kit Kat functionality and preferred stability and performance in my Android OS. Closer to stock android - was probably better for me. I looked into alternate ROMS and decided to install latest stable Cyanogen 10.2.1 and Google Apps. It met my criteria and seemed to have good support and stability.
Here are the instructions that outline the upgrade process best:
- Download 10.2 stable version to my PC - http://download.cyanogenmod.org/?device=spyder&type=stable
- Download Google Apps (GApps) for version 10.2 to my PC - http://wiki.cyanogenmod.org/w/Google_Apps

It's been 2 weeks since the change and here are my observations:
This upgraded the OS to Android 4.3. I found that Cyanogen 10.2 was amazingly fast on my phone and battery life was more than 48 hours with my normal usage. I did have to reinstall many applications and found Google Play kept track of previous apps. That made the process pretty easy.
I thought I'd miss a few of the custom Motorola apps (SmartActions, parking spot finder, car mode, corporate email, etc). I suspected that some of these apps were not playing well with Android updates and Motorola had abandoned development on them. I found Cyanogen had profiles (simple SmartActions), great Microsoft Outlook integration, and there were lots of choices in the play store for other things.
I did install LauncherPro to get a home screen that works in landscape mode in my car dock. Other than that I found that 10.2 gave a great user experience right out of the box.
I did have one day where my GPS stopped working. I ended up doing a cache wipe using SafeStrap and all my GPS functionality has been fine since. I even used SafeStrap to load the original configuration to verify it wasn't a hardware issue. Nice to know if something went really bad there was a path back to the original ROM.
I'm real happy with the change and should have done it six months ago. I can continue to use my older hardware and docking stations with great performance. I may get adventurous and install Kit Kat on the phone, but for right now I have a blazingly fast stable phone, great battery life, and a bloat free experience that I'm in control of.
Update 06-07-2014Once again the GPS on my Motorola XT912 stopped responding to any application. I use the GPS daily (Waze and FourSquare), so this is a big deal for me. This time I used saved Safestrap to wipe only the dalvik cache. You just reboot into Safestrap, go to the advanced menu, and select dalvik cache wipe. Then reboot. It takes a few minutes to reinitialize all the applications, but my GPS worked immediately again. I'll keep monitoring for the same problem.
