This can’t be an official 4.3 update, this is the exact same Vodafone Germany leak that SamMobile released 2 days ago, and this is obviously unfinished and unpolished.
For instance:
1. The lockscreen has many bugs and does not look and/or feel finished, here are some things I’ve noticed that bring me to this conclusion:
a. 4.3 does not have shortcut icons and does not give any way to activate them, yet 4.1.2 and 4.2.2 leak did.
b. Light effect is not working, it’s the same as if I selected “None”, yet the 4.2.2 leak had the Light effect working.
c. The Ripple effect is also the exact same one from 4.1.2, the 4.2.2 had an updated Ripple effect.
2. The amount of battery consumption is brutal compared to even the 4.2.2 leak which provided me over 24 hours of use, this one gets me 10 hours tops.
3. Memory management is also too high which tells me this is not finished software.
4. Calls drop for no reason even with full signal.
5. The phone becomes irresponsive at times, in fact, it got so bad for me today (about 40 secs without waking up) that I had to pull the battery.
6. The phone takes way too long to wake up from deep sleep and prompt to unlock… This must be linked to the 5th point.
7. The Touchwiz launcher, camera UI, S Planner (4.2.2 leak had a new S Planner), S Memo, Weather widget, 4×2 dual clock widget (4.2.2 leak had the new look with new fonts) are the same from 4.1.2. Let’s face it, these are just apps, all but the camera app had mere facelifts, it’s not like they will increase the RAM usage to levels that only phones with 2GB of RAM will handle… I’m pretty sure this is a test build that was missing memory management optimizations and could not add these apps before getting that solved.
8. KNOX is not present in this ROM, and though I don’t want it or miss it, this makes me believe that this is still unfinished.
This is what I’ve spotted, and with what I’ve learned from flashing ROMs and rooting, this is definitely not finished software, and I doubt that a corporation such as Samsung will half-ass such an important update for the 2nd best selling device, especially when this is supposed to add GALAXY Gear compatibility.
