How to reallocate more ROM for Android on Chuwi Hi10 Pro

I’ve had a Chuwi Hi10 Pro for a couple of years. I can use it on trips for small tasks I need in Windows but there is too little space for Android to do more than what standard Android installation has to offer. There is free space only for a few extra applications from PlayStore.

Is there a safe way to free space from Windows to expand space for Android. Could it be done with Windows Partition Manager. There is about ten partitions for Android. Which of them is the ROM partition. Windows can use SD-card to store data and apps. This Android version does not seem to be able to use SD-card to store applications.

To increase space for the android, you need to repartition all memory, and all the data on the tablet will be erased. :man_shrugging:

Could someone please explain how this is done exactly on the hi10? Some steps would be very helpful.
Thanks.
