I prepared short review for SlimKat 3.4 unofficial build for XT910 UMTS.
I use it for a last few days and my general impression is positive.
But lets start from beginning...
I use SafeStrap, so installation process is very easy: create slot, install software and gapps, clean cache and Dalvik cache. That's all.
After booting of phone there is sort setup and phone is ready to work. ALMOST...
After next restart phone stops connecting to network and to fix that problem it is necessary manually delete CellBroadcastReceiver.apk what is very easy because SlimKat is delivered with SlimCenter containing SlimSizer when user can delete any app.
So, delete it, reboot and forget about network connection problems. Why this app is delivered with most of KitKat ROMs for XT910 UMTS I do no understand. All of them have the same problem after rebooting.
2. Daily usage
I use it as my daily driver last days and it worked really good. I noticed just one crash when I used Any.do app but I cannot reproduce it so far.
Battery life is good for me - see BatteryLife.jpg attached. On the other hand I was totally surprised when I charged battery to 102% - see Battery102.jpg - really strange.
I turned system to use ART instead of Dalvik and I haven't noticed any problem so far. Every app I used worked properly. Of course app installation time is a bit longer now, but good information is that apps starts faster.
Call/receive calls - not problem. Sound is clean.
WiFi - I haven't noticed any problem with connection/disconnecting WiFi networks. Everything worked good.
GPS gets position really fat, I was very surprised with that.
SMS sending works properly but I still cannot send any MMS message. Nevermind data transmission is enabled. I does not work. To receive MMS data transmission must be enabled. This is the biggest bug I noticed.
Flip actions to dismiss call or alarm also don't work what confuses me. It worked perfectly in CARBON 4.2.2 version I used for long time.
It looks very strange in action: flip down - no action performed, flip up - phone seems to be blocked for some time and after a few seconds you can finally dismiss alarm or call.
Memory usage is much better than in 4.2.2 ROMs. After boot there is used 434MB and free 405MB of RAM with all of my services and widgets started. Great result.
Bleutooth I didn't test. I use it very seldom and it is not much important to me.
What was new for me - used apps display. It is changed in SlimKat - nice right side panel is displayed with list of used application.
Generally I must say that I like SlimKat. It has all options I really need to use it every day. I'm happy with Real dark option which turns system and most important apps into black theme, performance good enough without replacing kernel, ART support without problems and smoothness of GUI.
I hope that strange battery behavior and MMS sending problems will be fixed in next releases
And maybe XT910 will be officially supported by SlimKat team?
