Small root partion on ZGemma I55 Plus

[rasod]

Hi, can anybody explain why I got such a small root-partion om my ZGemma I55 Plus ( 202MB ) ?
While on my VuDuo2 the root partion is 862MB and on my VuDuo4KSE it is 3,48GB.
Is the amount of memory on ZGemma I55 Plus so small ?
If not, can you guys please extend the root partition on the next image, mine is about to be full.
