None of these problems exist with CM10.2. The only problem I will have is when the top drag down notification menu in pulled down sometimes it glitches up and stops at about half way down the screen and I need to tap the screen so that it resets and I can do it over again. Other than that everything works fine with 4.3 but when I install 4.4 (CM11) it's not stable at all on my phone.
I install it using clockwork mod recovery.
I wipe the /system, /data and /data/media (/sdcard), /data, /cache, wipe data/factory reset, wipe cache partition, wipe dalvik cache.
Then I install the cm-11-20140504-SNAPSHOT-M6-d2lte.zip
Then I install the gapps- kk-20140105-signed.zip
Then I do another wipe data/factory reset, wipe cache partition, wipe dalvik cache.
The only way I can do a cleaner wipe (that I know of) is to wipe my sdcard that I installed as extra memory, but I don't have another one and since most of my issues don't happen when I use 10.2.1 I havent gone forward with that option.
The rom I have the best luck with and is the one that I am referencing in this post as the 10.2.1 rom is cm-10.2.1-d2att.zip.
Anyone have any ideas? Am I missing a step? I otherwise really like CM11 and would like to use it all the time, but I work in the IT field and my phone is my assistant and I need something more reliable.
