Help App's data saving to internal memory

[Curious cat15]

Hi,

Is there any way to force all appsa to save data to external memory? I managed to root my mobile and move all apps to external memory but even after all that, apps are still saving data/cache in internal memory. For example, just running Facebook the app creates 50+MB data on internal memory.

Apps like DS Apps2SD Lite show no apps installed on internal memory but the memory is:
Total: 190MB, Used 160MB, Left: 30MB

I have Samsung GT-S5830i

I don't know that app, so do you know what it has moved? Just the apk, or apk + dalvik?

Anyway, it is possible. I believe that Link2SD can do it, and if not there were a number of data2sd or data2ext scripts developed back when devices with specs like yours were common (these days there is little demand for these things).

What you will need is a second partition on your card which is ext3 or ext4 format - it won't work with a fat32 partition. You also need init.d support in your ROM. With those 2 conditions met then try Link2SD, otherwise a web search on the other terms I mentioned will bring some results.

I'd recommend using GParted to add an ext-format partition (I do not recommend Minitool Partition Wizard - back in the Desire days we had to deal with so many people who'd followed guides that said to use than and then found that the tools couldn't use the partition it made). You should also definitely take a nandroid backup before trying this procedure.

SD cards, even good ones, are slower and less reliable than internal storage, so there will probably be a performance hit of some sort.

As above, but you have to use the Pro/paid version of Link2SD. The free version will only move apps but not data.
