Hey,
I've just taken delivery of my spanking new S6 (my first steps into the world of Android, from a previous Apple filled life)
I'm keen on security and I know Apple fully encrypt their phones as standard. I know that Android and manufacturers are not turning it as from the get go as I heard they don't want to damage their benchmarks (correct me if I'm wrong on any of this) my question is, does it actually slow it down that I would notice a difference? I'm keen to do it! Also, if I did encrypt it and I for some insane reason decided to turn it off, can I roll i roll it back?
Go easy, I'm a noob!

I encrypted my S6 several days ago.
Although I didn't do before and after benchmarks, my phone does not feel noticeably slower. I'd be surprised if there isn't an effect, it I can't tell.
The one exception is (re)boots. The first decryption adds approximately 30-60 seconds to boot time.
Finally, yes, you can decrypt the phone altogether if you need to for any reason.
Hope that helps!

Thank you for the reply. I'm not too fussed if its a little slower to boot, it rarely gets switched off.
I might go ahead and do it. Thanks.

Full Disc Encryption absolutely slows down your device. Anything that needs to use storage will run significantly slower. You will likely notice that apps load slower. Once an app is loaded performance won't be any different though.
FDE makes reads and writes to the disc about 3-5x slower.
Also you cannot simply turn off encryption. You pretty much have to factory reset your phone to get rid of the encryption. So if you want to go back, you need to backup all your apps and data, factory reset the phone, then reload all your apps and data.

My understanding is that this is not correct, though I am open to being wrong.
As for speeds, as I mentioned, I cannot comment on actual I/O speeds or benchmark results. I merely meant that subjectively, the phone remains blazing fast. I have no doubt synthetic benchmarks can detect what I cannot.

When I had my moto x 2013, encryption would wipe the phone if you turned it off. I wonder if they included a way around that with this phone. That would be pretty impressive

Can you still use fingerprints to unlock your phone?

Generally, yes.
If you do a soft reboot, you will be required to enter your backup password. From then on you can simply use he fingerprint until you boot again.
Got curious, did a little digging.
Here's AndroidAuthority's shot of an S6 benchmark (like I said, I didn't do any before encrypting, so I can't present my own)(first image)
I'm attaching a screenshot of the scores I just got, also using AnTuTu (second image)
Hi!
I'm very satisfied with the latest (1 March) 6.01 stock rom with cata mod on top of it.
I have never encrypted whole phone, I need to hear some pros and cons.
For example, if I encrypt it, I couldn't use any more swipe to unlock, only pin, that's OK. If I loose the phone, I will have less worries if it was encrypted, that's OK.
But what about speed, will I loose some speed (in everyday work, boot time) if enc?
Most important, will I be able to perform backup and restore from TWRP?
If I choose to enc, what is the procedure, I understand internal sdcard will also be encrypted?
Thanks in advance.
I have only Nexus devices (5 & 6), so I can't answer your SD card question.
I have used a N5 & N6 both encrypted and unencrypted, and I've read the report saying that there is a 50% performance hit (or whatever the figure is - it's supposed to be enormous in statistical terms) but in real-world usage there is no difference whatsoever that I can see. No stuttering, no lagging, no slow startup, absolutely nothing. If it takes an extra second to boot, I can't see it.
On the other hand, my wife lost her unencrypted Galaxy S2 a couple of months ago, so some slimy scumbag somewhere has access to our photos. No big deal, nothing embarrassing, but nevertheless I don't like the idea of some filthy lowlife creep looking at our personal family photos.
I tried Android N for a few days and didn't like the many apps that didn't work (including root, now resolved with SuperSU v2.70), so I restored my TWRP M backup. No problems whatsoever.
Go for it. I unreservedly encourage everybody to encrypt their devices. An imperceptible 5% hit is nothing to pay for peace of mind.

Very useful experience, thank you. By internal sdcard, i meant internal storage, not sdcard actually.
Ah, in that case, yes. I wasn't thinking...
Since the internal sdcard *is* the phone's data repository, it wouldn't make sense to leave it unencrypted...
I'm trying to decrypt my 3A to get a little better performance. I would like to know anyone can provide a step by step instruction.
I understand that all I need may just be flashing a zip with a modified file in TWRP then reset the phone. Unfortunately, I'm not savvy enough for preparing that.
Any one can assist?
Thank you.
Me too.
Isn't encryption on Pixels hardware accelerated and therefore has zero impact on performance? At least this is what I have read about the more expensive Pixel 3.
I personally prioritize security over a small performance impact. Encryption provides great benefits in the case of loosing or reselling the phone - your data is safe from unwanted access.
It would be nice if someone could post actual benchmarks before and after disabling encryption so that others can see if it is actually worth it.
There's zero benefit from permanently decrypting on pixels

Hardware accelerated means you still need resource to compute the encryption process. No matter how good it is, it will charge extra computation and battery anyway. The only way encryption may help would be not to leak phone information when you lose your phone. It will not happen if you care your phone enough.
If someone can provide the decryption method, I can run the benchmark to support what I say above for sure~

Really, this is your excuse?
And as far as the battery consumption goes, I think this will be a similar discussion as the dark gray vs. black OLED consumption, which saves you no more than a few seconds on a full charge.

Everything is decrypted using the Titan M processor, not the SD670. So disabling encryption would not help increase performance. Battery doesn't take much of a hit either. Maybe a few minutes at best would be saved.

Not an excuse. I only experience losing my phone for 1 time which was 14 years ago and the phone was found. Again, encrypting the phone takes extra step. Just not to do it if you could not bare the risk.
Personally, I would like to fight over the smallest trifles. It may just affect the performance and battery slightly and we can barely feel it, it is still hard for me to take it.

Do you unlock your phone? If so, your encryption is basically worthless.
Sure it might keep the casual user who finds a misplaced phone from getting information off of it. But anyone with even a slight interest in cracking the phone will be able to do it if it is unlocked. Please heed the boot warning on an unlocked phone states that an unlocked phone is insecure and that no sensitive information should be stored on it.

My phone locks after the screen turns off - either manually via power button or after 1 minute of idling. I can also lock / wipe it remotely, if needed.
I should also point out that wiping an un-encrypted device (either manual wipe or remote wipe) is totally ineffective and the "deleted" data can be very easily recovered.
In the end, it is your device with your data - do what you want with it. But disabling encryption offers zero performance improvement and negligible battery improvement.

the same as on any other phone unlock your bootloader install custom recovery format userdata and internal storage and flash a kernel that does not force encryption

I did that. It does not work. I did some research and it seems I have to edit a file to disable to force encryption.

Sorry, when I said "unlock your phone", I really meant bootloader unlock. I think you took it as a screen unlock. The way I wrote my comment, I totally understand the confusion.
If you bootloader unlock your phone (which many of us on this forum do to gain root), then the fact that your phone is encrypted is basically worthless. Now personally I would never worry about trying to permanently decrypt my phone even though I do bootloader unlock it, but I can understand why someone might want to.
Sorry, I misunderstood you before.
I am running an unmodified stock ROM and the bootloader was never unlocked.
Hi guys.
I recently switched to OnePlus ( 7 pro specifically ) and out of all the phones I've used, XS max, note 10, S10 ECT it's by far the best phone I've used. Although 1 small problem is lately my phone has been feeling like it's getting slower and slower, more and more lags seems to be happening, and things are taking a lot longer to open. Is anyone else experiencing this, or have any ideas what I could do?
Thanks in advance.
I have never experienced this. Best I could think of is to factory reset, start completely from scratch. Maybe root and try a custom kernel.

Yeah I've thought of that. I've only used 50% of my storage so I don't think that would be the case. My last resort was a factory reset and custom kernels/Roms ECT. I'll see what other ideas people have first then see how we go from there I think
Okay so I installed Beta 7 and it seems to be a bit better, still not as good as it was when I first purchased it though
Are you running android 10 or 9? I'm sticking with 9 because i had issues with 10 (so do many others) No signs of slowdown here. Ive played with a note 10 and it doesnt compare to the op7 pro in terms of performance.

I'm on 10, have thought about changing back to 9 but there's quite a few things I enjoy about 10, except the slowness.
Don't get me wrong when I first opened my 7 pro, my other devices including my S10 didn't even feel like they were in the same ball park, but now it just feels like it's getting sluggish.

It would really help by giving more info on what exactly you mean by "sluggishness". Are you saying general app opening speed/ sluggishness when typing emails/ slow bootup speeds? Where really is the problem...for all you know it could be a placebo effect or btw have you checked the screen refresh rate...is it 90hz or 60hz? Being on 90hz for so long, any other phone to me looks sluggish...

The whole phone, everything I do, nothing is instant anymore. And yes it's on 90hz, I agree I used my S10 the other day and it looked terrible scrolling through stuff compared to 90hz
I second the OP. I have an OP 7 Pro, 12GB version. And after software updates etc, I have seen slowness on my phone. However, after root and running FDE.AI once, looks much better. I have no documentation to prove that actually is the case though, maybe a placebo effect.

Funny, I can't see such sluggishness on my OP7Pro. It will be a joke to see sluggishness on these phones given that the phone specs are nothing short of desktop-level specs. I would highly recommend factory resetting your device or better yet starting right from scratch i.e. doing a fastboot stock rom flash using the latest update. This should (hopefully) iron out your issues. I'd also suggest being a bit careful on the apps that you install and rather not restore from google backups. It's best to start afresh (at least once in a while)
Just curious... Have you tried shutting off the animations or at sped them up?
I scaled mine down to 0 and my device is blazing fast now.

If you've used up 50% of your storage then of course the phone will be processing things slower than a phone that had nothing stored in it. That effect occurs with every device that has memory.

Well I've been at over 70% storage used for the past few months and have seen zero drop in performance. My pixel 2 xl is 80% storage used and it to performs as if it was bone stock. I have over 100 apps on my OP7 pro and haven't lost anything that I didn't have in terms of battery and performance. I swear I don't know what some people do with there phones but issues like these and battery usually come from poorly coded apps. You also can't download PornHub mobile and expect it not to come with consequence of some sort.

Kidding, but serious. I am not sure what's happening, maybe I have some app that's causing stupid issues I am not sure, I think I'm gonna factory reset and go from there I think.
So I've got a Note 20 ultra that I freaking love. I got the Pixel 6 pro as well and between the two of them I finally have settled my urge for vanilla, Android and everything. The Note 20 stood for. The problem, randomly. I was just out in the yard working. I went to check my notifications in my screen was black. Assuming the digitizer went because the device is still connected to some Bluetooth things.
I thought I saw $450 for a replacement, doesn't seem worth it considering I already have the pixel, what are my real options? What would you guys do? I freaking love the phone and have a million accessories for it.
Try a hard reboot.

Yay! It's a cheap trick, but great when it works.
If it continues to happen though it indicates a underlying firmware or hardware issue.

No need to do factory resets unless there's malware you can't delete or a 3rd app screws hidden user settings, or a major firmware upgrade.
This N10+ in my hand OS load will be 2 yo this June and is still stable and snappy fast with minimal maintenance. Still running on Pie.
I clear the system every month or so, and clean with SD Maid every month or so. Repair any damages made by misadventure or updates. That's it; stock Android's can be a very robust and stable platform.
