Help Memory issues on J5

[Andy Perrett]

I don't know if anybody thought of this or even if it is possible.
To speed up a pc we try defragmentation.
Is this possible on a smart phone. Say Samsung J5 ?

You shouldn't need to defrag them, as they don't contain a spinning drive....

If your device is slow, try to remove startup permissions for some apps you don't need.
You can do this by going to Settings>Security>App Permissions (on Android Lollipop at least).
Clean cache through recovery if needed.
Check if your CPU cores are running properly and if your RAM is alright or not, maybe it's your GPU...? Are you rooted?
Samsung is known for making high quality devices so if your device is slow there is something wrong and the cause might be an app you installed...
I hope it helps, good luck.

There's no performance advantage in defragmenting solid-state a.k.a. 'flash' memory as access times are the same regardless of where the data is stored on the drive. In fact it can actually hurt; flash memory has a finite lifetime in terms of the number of write cycles, and as the defragmentation process necessarily involves re-writing blocks of data it will inevitably shorten the MLTF.

Thanks for all replies.
I only thought that the fat maybe could use some cleaning up. I do presume that even solid state uses a fat ?

When your Android/iOS device is slow it usually is related to apps/CPU cores/GPU and not the actual drive of the device so I wouldn't worry about that.

FAT is an outdated file system that even Microsoft no longer relies upon. It is however a curse that will remain with all of us for some time as that's the default for microSD cards. So no, the NAND flash memory chips in our phones do not use FAT, they use ext.

One of the major issues with microSD cards are those fragile FAT file systems, easily corruptible but still hanging around because of its legacy compatibility with multiple operating systems.
