I've heard that doing so alleviates some lag that people have been complaining about. Any truth to this?
First of all, please note that disabling decryption requires root, which also requires doing a factory reset. While disabling encryption will certainly speed up the phone, Google has improved encryption in Android Marshmallow so that it doesn't decrease performance as much as it did in Lollipop. You may not notice the difference. As for a factory reset, it will certainly get rid of any lag caused by any changes you made to the phone, but not any caused by Android.

Root and decryption are two different things. It seems you can have either or both. I'm curious to know if decryption carries a better experience myself also. I don't really care about benchmarks, mostly if it eliminates lag.
Every post I've read has said that they haven't noticed a difference between decrypted and encrypted with the 5X - though I haven't seen any benchmarks comparing. If it helps, the Ars Technica review shows how the I/O performance compares to previous phones. (3rd graph set in the Performance section)
I'm not sure whether it is actually a Marshmallow specific feature or not, but the 5X and the 6P are using the cryptography extensions that are part of the ARMv8 instruction set to perform encryption and decryption. The performance hit should be negligible.
Everyone clearly remembers the bad rep the N6 has for this, but it just didn't have proper support for this feature, though it apparently got a bit better later on. Right now it seems like jumping at ghosts for the 5X & 6P.
OP, which android build are you on? I'm wondering if the I build makes a difference. At least one person has returned their phone due to the lag, and had a replacement that didn't have that issue.
i was experiencing random lag with my n5x and I ended decrypting the phone and disabling zram and it made a big difference.
Before doing this, my phone was noticeably laggier and slower than my nexus 6 (decrypted). After decrypting and disabling zram, my n5x is now just as fast as my n6.
I did a speed test like those youtube videos, where you open apps at the same time and see which one finishes first, and now the n6 and n5x both finish opening apps almost exactly at the same time.
My build is mda89e. I don't have any noticeable lag, I was just curious if it would change anything.
How would you characterize the lag if it were present?
I decrypted and rooted, did not notice any difference in daily use. (dont care for benchmarks) I did however notice that the phone boots much faster after decryption.

Use trickster mod or kernel auditor to disable it.

Hi
Disabling ZRAM will wear out your flash memory quicker, the whole point of ZRAM is to speed up the phone and protect flash memory from hundreds or thousands of tiny write operations.
From the Wiki (https://en.wikipedia.org/wiki/Zram)
zram increases performance by avoiding paging to disk and using a compressed block device in RAM instead, inside which paging takes place until it is necessary to use the swap space on a hard disk drive. Since using RAM is an alternative way to provide swapping on RAM, zram allows Linux to make more use of RAM when swapping/paging is required, especially on older computers with less RAM installed.[1][2]
Even when the cost of RAM is low, zram still offers advantages for low-end hardware devices such as embedded devices and netbooks. Such devices usually use flash-based storage that has limited lifespan due to its nature, which is also used to provide swap space. The reduction in swap usage as a result of using zram effectively reduces the amount of wear placed on such flash-based storage, resulting in prolonging its usable life. Also, using zram results in a significantly reduced I/O for Linux systems that require swapping.[3][4]

Decryption doesn't make much difference (it will speed up boot times if you had a power on password, but that is simply because it is booting twice to offer us a protected Android environment first to get the password, and this was optional anyway, we get the choice during setup). The whole phone isn't encrypted anyway, just user data, hence overall the difference between encrypted and decrypted isn't that wide.
Unless we have some evidence of the speed up, I'm tempted to put down any suggestion of speed up down to the placebo effect :laugh:
If there is an improvement, It might be as simple as a factory reset is good for the phone due to some optimization undertaken with the flash memory at that time, or recompiling apps, that has been skipped when loading the device with an image at the factory. Perhaps that is why some people are seeing no problems with lag because they've played about first and had a mess around, then did a factory reset at some point to set up their device up as a daily driver.
A true test would be to do factory reset with everything at defaults, run a measured test, then decrypt and remove ZRAM and do a second test.
Regards
Phil
This is wrong. Disabling zram doesn't mean u are adding a swap to the flash, so the kernel isn't going to write to the flash.
You have no idea what you are talking about.

Hi all- I am thinking about getting the 5X as a replacement for my wife's faltering Lumia.She has had the Lumia for about 1.5 years and it has been great but lately the battery is dying quickly and it is prone to freezing,and there is no way to power it off!You have to wait for it to die and then restart.
I have read that the drawbacks of the 5X are poor battery life and a stuttering UI.The Lumia always had great battery and was buttery smooth as well as having an amazing camera so I don't want the 5X to feel like a downgrade.
I have been flashing since I had my Droid Incredible way back when so I would have no problem with applying a Custom ROM to the 5X to smooth out the experience.
So I am looking for ROM recommendations that deal with the stock units shortcomings.I am guessing that installing Chroma or Pure Nexus or some other custom ROM will tackle those issues.
Thanks!
If you notice in the threads that people complain about a laggy UI there are just as many users saying they have never experienced that issue. I'm one of the latter.
Decrypt the phone and install Pure Nexus, that's all I needed for a perfect user experience. :good:

Good to know-that's about what I figured.Thanks for the feedback!
Stock device here with no performance or battery issues, I don't even have root access or need to reboot my device. Just do a clean install and don't restore from a previous device as many of those with issues seem to have done so.
The camera is one of the best in a smartphone right now (same as Nexus 6p), as is the highly accurate IPS panel tested to be more accurate than the one used with the more expensive iPhone 6s.
i would give it a week and use the phone as it comes (apart from maybe an adblocker, which for me is a mandatory thing). honestly the 5x is a great device, and a lot of those shortcomings that are talked about in reality turn out to be related to certain apps.
as you may guess, my own device is still on stock and i feel no need at all for another rom. battery life is great, fast charging is a great feature, and apps on my end start up near instantaneous even though the phone is encrypted.
of course there are some mild annoyances as with every other device and OS. when it comes to the 5x these were basically limited to doze, which is a great feature, which may have to be manually disabled for certain apps like GMail.
in the end it comes down to your wifes habits, the apps and usage, and the expectations she brings upon her phone. see if she is pleased with the phone (at all). if she isn't you can then take on those issues specifically. after all the closer you stay to stock, the less maintenance there is to do.

Pretty sound advice-she is not a power user.Or a heavy App user either.Just basic functions and she will be used to a great Camera so that matters.Stock may be just fine for her but I also know the power of a well-developed ROM can make a good or great device even better. Thanks for the input.
Have had mine since launch. Battery life is fine (lasts morning to evening with heave use; 24+ hours on light to moderate use), and the device does not stutter. UI is smooth and the device multitasks well. I am stock, unrooted, and encrypted. I don't game, however.
The only two criticisms of the 5X that I feel are at all valid are: an average (at best) speakerphone; and low output from the headphone jack. With regard to the former, the speaker will get the job done but is definitely not great. With regard to the latter, the 5X supports USB audio so if you are really serious about your music that's the way to go.
From what I have seen here and on reddit, it really is a good idea not to restore from a previous device. It does seem to be something of a common factor among folks that claim to have issues.

Good to know-well we would be setting up a fresh device,no restore for sure.
I had Volume issues on my Nexus 6 only when playing music oddly.Phone and Bluetooth and GPS were actually quite loud and I had to adjust down.You need Root,but with ES File Explorer I was able to edit the “mixer_paths.xml” file and setting all values that were "84" to "99" solved my problem.Not sure if that would work on a 5X although in theory it should,perhaps there may be a similar hack that a Google search would uncover.Thanks for the input.
I'm not sure where else to put this (I searched and found nothing) but has anyone else been impressed by this phones ability to remain cool to the touch? I'm using the stock case that came with the US variant of the phone and aside from an APN issue where signals were going insane and the radio tried to connect to a billion different towers, I have not once noticed the phone getting much above ambient temperature.
Is this normal? Can anyone else confirm that this thing just doesn't get hot?
I'm bringing this up because I've owned/used around 30 different smartphones from all of the major manufacturers and the vast majority get quite warm during several normal tasks.
For instance, on most phones I've used, if the brightness is up and I'm gaming for any extended period of time the phone will get quite warm. If I'm charging and browsing the web, most phones will warm right up. If I'm gaming and charging at the same time, things get toasty. If I'm gaming and quickcharging/turbocharging things get pretty bad. If I'm gaming on a "practically magic" iPhone while it's charging- forget about it. Same goes for most phones and video recording.
The Le Pro 3 has remained completely usable during all of those tasks. It's actually downright creepy being able to heavily game on full brightness while quickcharging without my fingertip being on fire within a few minutes.

This is supposed to be the benefit of the Snapdragon 821 processor; fast but at the same time power efficient....
I hear you. Playing Pokemon Go with a Pro 3 is smooth and cool, I can say that playing for about 10 minutes straight and it gets warm, but not hot. Unlike playing it with my One Plus One, a 5 minute session and it gets hot. This phone totally surprised me :good:

Obviously they've made strides, but its not just the chipset. Reviews of the pixel, ZTE and Asus 821 phone all mention how the 821 is better than 820 (lol, as in it can't cook an egg) but they all say it gets warm and the pixels seem to have significant heat issues.
The battery isn't getting massively hot even under quick charge despite being enormous and charging very quickly for its size. The screen doesn't seem to emit much heat either though it's not some AMOLED qhd monster but still. I mean it's obvious that the CPU is right below the fingerprint reader as it does get warm but nothing even gets what I'd consider hot especially for a modern flagshipish smartphone.
I've used supposedly power sipping/efficient chipset before as well as stuff like the original moto x which was literally a heat bomb and none of them have done so well. I'm sure it's not the actual best temperature that a phone has ever been but it's like night and day for me!
Kudos to Qualcomm or LeEco or the battery manufacturer or the screen supplier- they all seem to have gotten it right with regards to heat and efficiency.
I even have the speed up box enabled for all relevant apps and have turned off most power saving stuff and the phone is still cooler than every modern smartphone phone I've used including hugely underpowered ones.

Good to know, if anyone else has this issue - mine was deleting T-Mobiles default APN and making a MetroPCS one (incorrectly), then deleting that and having it automatically revert back to T-Mobile. Once I cleared everything and manually put Metros APN stuff correctly everything cleared up and has been fine since.
But during that half morning when I couldn't figure out the issue my Pro3 was getting quite warm and I was ready to return the thing. The issue remained even after a factory reset until I manually adjusted the APN.

My situation was different then. APN was fine but it somehow kept frequently switching LTE bands/towers my carrier offer which caused ever frequent signal fluctuation.
Nothing could fix it until I moved to CM.
Any thoughts on when LineageOS or alternatives will run on the S22 ?
I'd like to use LineageOS primarily because my battery will last longer and I don't mind running Android 12, doesn't need to be the latest.
Are there any options open to me or do I need to wait some months or just buy an S21 ?
I would get the N10+ running on Android 10, no higher. Other than the smoothness of the display and the slight cam improvements it's a better phone.
The fact that a 3yo flagship can effectively compete with the latest Samsung/Google Adroid OS version shows how badly both have dropped the ball.
Hopefully there will be an GSI that runs well on the exynos S22, phh has got an S22.
Little hope for any aosplike roms tho
foe me its not worth loosing waranty and features from one ui. check the other threads with my attempts
final version for exynos s22 is this:
i recommend galaxy max hz. didnt even touch the refresh rates.
use doze settings with all sensors off. im back to s21 6hr sot using this method.
also turn wifi off when screem off untill samsung fixes the firmware. i use a few tasker profiles and kwgt/nova launcher. without them i think the drain would be even lower. standby drain is under 1%/h
slight debloat and degoglify the phone . use the apps you need only
good luck and come back with the results

Does the doze settings disable push notifications?
yes.it delays then. but you can skip doze for the apps you need notifications instantly by disabling battery optimization for those apps

Indeed, take out the trash...
You'll just lose functionality by going to a generic OS. One UI, the spen, the cams are big reasons people buy Samsung's. This phone is not Samsung's best effort but that doesn't mean it can't be optimized into something that runs a lot better then it is now... without updates.
Play with it and find your own workarounds.
Once you learn how to optimize that OS version, stay on it unless the upgrade is proven good and adds substantial value to your device's mission.
Don't except token trinket upgrades that cost you lost time and device usability/functionality.
If you're like me and only intended to change the battery in order to keep it going for a bit longer or bought it 2nd hand then think again. There's a high likelyhood of it having a bad wifi chip in both the S8 and S9 which'll drain the battery like crazy if you have the Exynos variant. And this can easily be tested by just downloading something heavy and turning off wifi to see battery usage drop from 3-6W down to <400mW with something like Accubattery or your fav battery monitoring tool (i.e EX KM or whathaveyou).
I thought I was crazy at first since the CPU was maxing out (or close to) for no apparent reason when I was just refreshing my reading app, but it turns out it's the WiFi IC that is at fault. It didn't go bad during my first 2 years but around 2021 I started having issues so I switched my DD to my XZ2 and only kept my S9 as a backup unit.
Now obviously the other telltale sign is that the phone will overheat and drain the battery rather fast which I always thought was just the Exynos being Exynos but it's actually the Wifi chip. I got an Xperia XZ1/2 as well were the WiFI IC is part of the SOC so there's no actual issue there since Qualcomm make their own chips for everything more or less. If you've ever had a Broadcom moment then you know what you're up against.
I feel sad for letting this device go since it was my fav phone for so long but it's finally time to say goodbye since RAM has become the next issue on my list.
Does it happen in safe mode?
Guess you already tried a network reset and clearing the system cache?
It happens regardless of what I do but it's not the first time I've had issues like these. And anyone with broadcom experience will know exactly what I'm talking about.
