I did a factory reset last week and I am slowly adding back the relatively small number of apps I had installed. I had been getting random Droid lock-ups and decided it was time to wipe it and see where the problems start as I slowly reinstall my apps.
After the reset, I put a few of the most important apps back on: SplashID, Google Maps, AK Notepad and Astro. 100% reliability for a number of days, just like the first six weeks of Droid ownership.
Pro Zoom 5x was next - so I installed it yesterday. First thing I got when I ran it was a FC - nice. Then, it gave me an error that my Gallery doesn't exist, unless I put a file from PZ5x in it. If I deleted the file created in PZ5x? My gallery didn't exist again.
Everything was perfect until this app was installed. Still, it hasn't done a random lock-up yet, so I am not sure that PZ5x was the/a culprit, but this does not bode well for the stability of this app.
I'll keep an eye on it over the next week, and if the reliability/stability of my Droid drops again, it's PZ5x that will be the first to go.
