SONY Xperia Z1

In my case of as a user of SONY Xperia Z1, This bulkily brother has only 16GB internal NAND flash size, and actually I can use only about 11GB of free space in stock ROM. This big brother used Qualcomm snapdragon 801 and installed 2GB of DDR3 memory, but stock apps are already running on memory even I don’t have plan to use them in above half of system memory. finally free memory only left in about 700 to 800MB of 1900MB, wow.

Acutally this is not a product of Google or AOSP. So it can’t be expected like original android devices – Nexus series. But I was sure it be going to lighter than stock-system and I did it.

First It must be prepared like this:

  • It must be installed 1.14A.157 or 108 build as Android 4.4.x
  • Fresh factory reseted.
  • Prepare latest verison S1 Flashtool with driver, kernel only FTF files.
  • Rooting script for stock 1.14A.108 (and replace SuperSU.apk with latest)
  • ES Explorer on Google Play Store.

Now be a rooted device with our XDA brother’s good ways. ( I can’t explain whole things to do… ) Just replace 157 kernel to 108. And Run rooting script for exploit with ADB. Got rooted ? just remove useless apps in stock ROM with ES Explorer ( and it must be gain root explorer mode)

  • All small applications with launcher and manager ( these are appears when you touched a rectangle icon of soft navigation bar on bottom of screen )
  • Most of SONY apps except WALKMAN, audio effect manager and camera …
  • Simple Home – I don’t have plan to use this ugly launcher in 5″ display.
  • Active Clip and supporting apps – I don’t exepct anything from SONY as you may know.
  • SONY social junk apps – why I need these sh*ts ?
  • All helper apps like karaoke on Youtube ?
  • File Commander – A really big junk, hugh …

After removing all apps (maybe you should back up all apps before remove/uninstall), you should check your using memory state. Normally it overs about 1.2 to 1.3GB in used, but after removed junks, it diet to 700 to 800MB.

I know android system always caching their apps on memory for quick responsibilities. But if it included unwanted apps even it disturbe my using style and never possible to uninstall from app manager !? It’s hell.

Think about File commander app in stock ROM. This junk app has no useful functions if you have pay for their premium slave. And it is expensive ! USD 5? I will remove this junk and replace ES explorer to system app.

And don’t forget external SD write permission for Android’s big miss.

  • ┬áMove to directory “/system/etc/permissions”.
  • Find a file “platform.xml” and open it.
  • Find below sections and edit. (red color means added) , then save.

<permission name=”android.permission.WRITE_EXTERNAL_STORAGE” >
<group gid=”sdcard_r” />
<group gid=”sdcard_rw” />
<group gid=”media_rw” />

<permission name=”android.permission.WRITE_MEDIA_STORAGE” >
<group gid=”sdcard_rw” />
<group gid=”media_rw” />

Ok, If you think it’s done for clean up, self remove SuperSU, and turn off your phone. and go for flashmode. Update stock kernel 108 to 157 and reboot.

Your phone became to healthy.
