If I encrypt, will the whole system be much slower?

[Q] System apps.

Do you win anything by making your apps as system apps?
Apps
If you user apps become moved to the system partition, it'll take the space on your system partition instead of your data partition. If you flash the system partition again, the user app that was moved will be overwritten and removed. It won't actually make any difference in speed.
So, the ones in /data/app stays after flashing new rom?

As long as you don't factory reset, usually they will stay there.
Good to know when getting updates (at least of some roms).

[Q] Partition Cleanup Question

After flashing a number of ROMs over the past year and a half or so, storage has been used up though the values don't add up to 16GB. Think that there are partitions consuming storage. Is there a way to safely clean this up?
Noob here trying to understand and appreciate your help

LG G2 Custom Rom Encryption

I do understand the basic concepts of encrypting.
My guess is that encryption is done for /data and /sdcard and perhaps some other data.
When i encrypt my phone. And im using G3 custom rom on G2. Will i be able to flash zip file from internal memory. Directry or via adb.
So basically has anyone done this?? Any explanations or suggestions????

Did you ever get anywhere with this? I really want to get the G3 UI, but I have forced encryption policy applied for use of corp email. I have yet to get encryption to run after loading a custom ROM, nor have I been able to get a custom ROM to install on an already encrypted phone.

[Q] Selling S4 - Secure Wipe

Hi All,
I'm selling my S4 and I've been reading up on how to secure wipe it. I've been reading that encrypting and then wiping will render the data useless as the key is lost.
I've already factory reset my phone before encrypting it. If i fill the internal SD with junk and encrypt it will this have the same result as it's overwriting the previously occupied space?
Thanks
You shouldn't need to fill the internal storage with junk before encrypting. The very act of encrypting, even on an empty drive, should destroy the pointers to the old data. From there, factory reset and sell.

[Q] How to reduce system data

Hi all,
since our LG g2 cannot be expanded with an SD-card we need to be a little economical with our RAM. What strikes me first after I have installed stock Lollipop is almost 6 GB of System Data! as others can confirm, too

Is there a possibility to reduce this?

There's no 6GB of system data, there's probably just a couple of gigabytes. There is, however, a 6GB partition reserved for the system. This means that the only way to "empty" up the space from this partition is to re-partition the device (move parts of the /system/ partition into /data/), which is, as far as I know, impossible under a locked bootloader.
