I do see android keyboard stop from time to time. And, the play store does disappear at times while doing updates. But, i don't see a fc popup. This does seem to be the smoothest lollipop rom so far.I tried a Full Wipe and flashed v5.4.5 , wipe cache then boot. I then flashed the "smallest gapps " package and wiped cache again, then boot. The force close is no longer limited to Google Play Services, or system apps. It is happening to random user apps although Google related are more common.
This force close issue is fairly well documented with a little research and happens to my stock Galaxy S6 frequently also. My S6 Edge seems unaffected. (Rooted with custom ROM and kernel. Just my 2 cents but I think it has nothing to do with this ROM and everything to do with the recent update of Google play services...
OK, I installed the CORRECT Play Services apk for 320dpi this time and still have the f/c happening. Time for a ,correction, several beer break!
