With phones, the primary storage is typically soldered down to the logic board along with any other components such as the processor and memory to name just two others. By running a quick search, it seems that the 610 does have expandable storage if you have run out, meaning you can simply slot in an SD card. Once you have installed the SD card, you can move over your apps if you have a storage problem by doing the following:
- From the Home screen, swipe up and then tap Settings > Storage.
- Under Portable storage, tap next to the storage card name.
- Tap Format as internal > Erase & format > Format.
- Follow the onscreen instructions to move your installed apps and their data from the phone storage to the storage card.
If, however, you have got a corrupted storage chip on your phone, you might be out of luck for a quick, cheap, simply fix like the one listed above, and would have to resort to physically desoldering the storage chip on the phone and replacing it with one that has been verified. My honest opinion, is that if that’s the case then you would be better off with a new phone as you would need a broken phone of the same variety in order to get the correct storage chip.
