I have searched around the net but not really finding exact problems nor solution related to mine.

I have a tablet which should have 8gb of internal memory but the problem is that it have divided memory onto 2 partitions as data storage and internal storage and i have lack of space on my data storage as its only 1gb while other partition uses rest of the internal storage.

So i cant install any more apps as my data storage is full while second partition is almost empty.

I have actually tried to flash emmc and new android but i got the same partition sizes.

My device is BlueBerry Netcat M-28, this should be rebranded chinese Cube tablet as i know. Anyway the model is from 2014 and uses:

Android 4.2.2 Baseband version MOLY.WR8.W1315 Kernel version 3.4.5 build Jan 2014 HKT(i guess this is hong kong time)

Mediatek ARM Dual Core MT8312 1.2GHz

Just for the note: I don't know much about android except that it's based on linux, at least the same kernel? But i do know my way around the linux, still android is unfamiliar to me. I had a same problem with space on my mobile phone Nokia N900 which runs on linux maemo, the phone have 32gb memory which was divided into 2gb and 26gb and 2gb was not enough. But on Nokia there was no problem, i was easily able to find flash tools, new firmware, modified kernel. It was just needed to ,modify file with hex editor and flash emmc with new settings od 8gb and 20gb partitions.

Why isn't possible something like this on tablet too?

  • What device & ROM (or Android Version) are you using? – Gokul NC Dec 26 '15 at 17:15
  • As far as I know, the applications, app data and internal storage are present in the /data partition. So, space will be shared by both app data & internal storage. Maybe your device model is somewhat old I guess, in which app data & internal storage are different partitions. – Gokul NC Dec 26 '15 at 17:15
  • I updated my question with the info you asked. I read about in the net that it's possible that this is because android 4.2 version, in later versions 4.4 devices have one big internal partition. At least that's on my brother's phone lenovo. – Aleksandar Đorđević Dec 26 '15 at 18:06
  • Is your phone rooted? Is there a custom recovery for your phone? – Gokul NC Dec 27 '15 at 3:54
  • It's rooted, i unlocked it with some app from google store, i can't remember, and there is only basic backup restore app that came pre installed from android. I don't care about losing data, i don't keep anything important on the phone and i copied all the photos to pc already. I am just worried not to brick it in process. – Aleksandar Đorđević Dec 27 '15 at 9:52
