But, there apps country locked. I can't download in Play Store. I got smartband last week
Apk extraction is so easy. Run the ASTRO File Manager and then do the backup apps.
Here is the lifelog apk!
I've just downloaded it from the Play Store and it installed fine on my Z1 with official 4.4.2 KK. It can also be started and works.
I then grabbed the app from my phone and uploaded it here for others to enjoy who might not be able to download it yet.
(This is not from the Z2 system dump as this version won't work, at least not for me!)
