A relative of mine has a Sony Xperia M4 (E2303), with only 8 Gb. of internal memory. Of course, it comes preloaded with all the Sony bloatware (games centers, music store, etc.) AND all the Google bloatware, and they can't be removed, AFAIK.
Currently, the phone reports only around 320Mb. of free internal memory, and therefore it can't be upgraded to new Android versions, even though they show up as available; when you try to download them, the warning about "not enough memory" appears. The same when you try to upgrade an app like Whatsapp.
We have already moved every app that we could to the external SD card, as well as every photo, music file, etc.; in fact, when you go to "Settings/Storage" to try to transfer data to the card, nothing shows up, because everything that could be moved has been already.
Given this, what are our options in order to upgrade this phone, or its apps?
- If I have to install a custom ROM, I will, but I'd like recommendations on whether the existing ones for this model are stable.
- If there's any way to delete the unneeded bloatware, that would be great.
