[Q] Encrypting the Note 8: Performance Impact? - Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti

Greetings!
For various reasons I'm thinking about encrypting my Note 8 (and the removable MicroSD card). I would welcome anyone's experience with encrypting the Note 8 regarding the following:
1) Is the performance impact noticeable (ie, does it feel more more sluggish, and if so, in what contexts)?
2) Was any impact on battery life noticeable?
I am on Android 4.2.2. I am interested in the above with regards to that version, as well as KitKat 4.4.2 (since there may be differences).
I'm not interested in discussion regarding the "why" of encryption (as in, Why am I considering this?)--I'm not looking to think through that in the context of this thread (or at least not at the moment). And I'm aware of the standard things such as, once I encrypt I will have to do a Factory Reset if I change my mind.
From what I've read encryption can/does effect performance and battery life in general, but is very device-dependent as far as whether the difference is significant or noticeable (hence my interest in people's experiences).
Thanks in advance to any who decide to share their experiences!

[Q] Help with different MIUI versions?

I've been really interested in the development in the MIUI ROM for the Desire and have tried some of XavierJohn22's offerings. The progress seems excellent and I love the look of the UI, (despite it's obvious comparisons with iOS...) and the increases in performance / battery life compared to the stock ROM.
What I'm not sure of, (and I have trawled through the forums looking for the answers!) are the differences in both functionality and advancements in development, between the variants that are on offer - namely the MIUI AU version, MarkHUK's (miui-dev) and those by XJ.
To add to the confusion, what are the differences between the 3 versions XJ has compiled? (a2sd, x-part and d2w)
Are there any benefits that would favour one over the others?
What are the benefits in moving the caches onto the SD card apart from the obvious space gains on the phone?
Is there any loss of performance?
Also, I've read that performance can be greatly improved by flashing a Froyo kernel into the Gingerbread build (MIUI 1.4.1). Surely a downgrade of kernel would also downgrade the system back to Froyo?
I appreciate these may be very noobish type questions, but I really want to learn this!
If anyone can provide any answers I would be very grateful.
P.S. Before this thread gets removed again, would someone care to let me know the reasons for deletion?

These are just different build from different chefs, the main difference is that they make their rom the way they want them. Beside that one rom could use a newer version of miui then the other.

The only advantage is more space on your phone. There could be performance loss but that depends on your SDcard and some other factors. Stick with a2sd and then if you haven't got enough space (which I doubt) you could try some other versions.
Also, I've read that performance can be greatly improved by flashing a Froyo kernel into the Gingerbread build (MIUI 1.4.1). Surely a downgrade of kernel would also downgrade the system back to Froyo?

A froyo kernel is for froyo and a gingerbread kernel for gingerbread. You don't use one with the other.
You can get improvements with different kernels but you just need to read and test for yourself. The main improvements could be better batterie life, but because it's depends a lot on the hardware of your phone, you should test this yourself.
Chances are it's cause you posted a question in the wrong forum, hence its movement

What is your opinion about Lollipop ? Should I update ?

Coming from an iPhone 4S, I am very glad with the Sony Xperia Z1C that I bought a few months ago to replace it. The Z1C is still running on KitKat and it works perfectly fine. It is not rooted btw.
Now I am considering to update to Lollipop, but I wonder if that would be wise. On various forums, e.g. the Sony support forum, I read some "horror stories" (o.k. a bit exaggerated maybe) about decreased battery life, overheating etc. after a Lollipop update.
I already asked for an opinion on the Sony forum, but got an, imo, rather meaningless reply saying that earlier updates also had many complaints and the started thread was locked almost immediately by a moderator after that reply.
Now I hope that I can get some advice here. Is there a more or less general consensus here about updating or not ?
Thanks in advance.
I have absolutely no complains about this update. Still have great battery life, but no overheating or whatsoever. The phone is as pleasant to use use as before the update if not more
Opinions differ. Some specialists from this forum reverted from LP to KK for different reasons.
My personal opinion is that with every step ahead software becomes more complicated, investigates you and your activities in bigger grade and is more troublesome during rooting and personal modifications.
Since long ago my principal rule is: "Don't touch things which work correctly".
I am still on KK .108 however I tuned it in 100+ places to suit my needs.
I had crapy sound problem and don't recommend lollipop yet.

Exactly.
For me, update to lollipop is a completely waste of time unfortunately again on 5.1.1. Poor multitasking, camera quality worst than kitkat (whitish tone on captured pictures and viewfinder lag in medium or low light conditions), battery draining... I prefer stability, performance and battery of kitkat than smoothness or visual changes from lollipop
performance on LP is better than KK. see aututu, it got 2000-3000 points more.
remember its a phone, and its better than 90% of the phones out there. it will never be S6 edge or whatever.
i like the smoothness in 5.1.1. if it was KK it would stand still for a sec or two, makes it feel slow, like this that is covered in animations.
about multitasking, got no issues, FB and the chat are great, instagram is fast, skype and viber work nice. 2 years almost and still kicking.
5.0.2 was laggy, and poor battery life.
5.1 is quick, good battery life, good multitasking.
The only thing worse about LP is the camera refresh rate. It look lower than 20fps (with KK it looks to be 60fps).

From a technical standpoint, according to munjeni, who is well recognized as very knowledgeable in these things, KK is better, (.108 firmware specifically). He has a lot to say about it in his thread for his stock based LP ROM. Personally, I don't know much about all that, so for me it's more about user experience and trying something new. I like to go back and forth. I guess it just depends on what your priorities are.

It's exactly my opinion too buddy :good: and since, from what I read here, there is too much discordance amongst opinion, I think I'm going to keep faith to this mantra still for a long of time LOL

Well. This IS a point, especially if you have free time to spend.
Otherwise I suggest to root phone, tune sound, camera, fast dormancy, gps.conf, remove bloatware, use better battery stats to tune battery usage, install Xposed modules and do more similar actions.
No comparison to branded phone.
LP is great regarding the user experience (visuals and animations) and I was able to get rid of a couple of apps after switching from KK (lock screen notifications, bt watch keeping device unlocked -> smart lock). Performance and battery life are still ok and I can not notice any difference.
but ... if you are considering moving to cm12.1
you should wait until the wifi / bt bug has been fixed, which is a major problem
and there is an issue with AudioFX (equalizer) that keeps crashing, which is annoying

Breath new life?

Hi all,
This is my first time here and feel very humble amongst you all. I come here to gain knowledge on how to breath new life into my old Samsung Galaxy Nexus.
Questions:
1) Would I be wasting my time trying to make my old faithful better?
2) Is it possible to update the firmware to simulate newer versions of Android?
3) I would like to use Android Pay, can this be achieved?
4) I understand the phone's hardware is not compatible with 4G but can any improvements be made?
5) Could I carry out any form of modifications myself with help from you guys?
BTW, I have performed a factory reset last week and the internet feels slightly quicker for whatever reason!
I'm not too bothered if anything fails as I am thinking of buying a Nexus 5X anyway but would just like to see what differences could be done.
Many thanks and I look forward to any replies given.
Thank you.

Well, I'm not a developer either but I can tell from my experience that you can breathe new life into your GNex.
I did so in 2014 when I decided to install CM11. Everything worked just fine except for one problem I encountered in connection with the
Google apps I installed as well - there was about 4-5% battery drain/hour in stand-by which I was not willing to accept. So I decided to
scrap all google apps and after flashing CM 11 without goolge apps I was back to 1%/hour (or even less) during stand-by. Apps can be found on F-droid or aptoide.
I still use it as a daily driver because it serves my needs perfectly. At present I have CM12 nightlies running and they good for daily use.
Battery life is very good; camera issues (videos used to have a small green/purple line on one edge) are gone and overall performance and stability is very good.
However, I can not tell whether Android Pay works as I do not have G-apps installed and I guess that you will not be able to do anything regarding 4G.
There are special kernel-versions that allow a higher CPU-rate; at least they existed for CM11 /Android 4.4.
I found this link on a German linux blog:
http://forum.xda-developers.com/galaxy-nexus/development/kernel-fancy-kernel-r50-t2115590
Anyway, you can still use it as a daily driver and spend the money for a new device for other purposes.

Should I Root My 10?

So I've had the phone for a while, I am confident there are no physical faults and don't mind partially voiding my warranty. I've always struggled with battery life and ever since the Nougat update, my phone has been slowing down and experiencing some random issues such as very high WiFi latency and small 1-2s freezes.
Obviously a factory reset is in order and since I'm going to wipe the phone anyway, I was thinking I might root it as I have rooted all my past HTC phones; the only reason why I haven't rooted the 10 was because I was content with its performance (was) and I was waiting for Nougat, which I finally received.
Since the 10 might get Android O in the future, and it would be much easier to update over OTA, I was curious how everyone's experiences with custom ROMs and Kernels on the 10 has been? Have you experienced noticeably better battery life, performance, etc, what ROM/Kernel combinations do you guys recommend? Do you think rooting is a good choice?
Any comments welcome!

I root all of my devices but for specific reasons. I like to be able to remove unwanted applications and logging, I only want what I want running on my device. I also root to block ads with adaway, although there are alternative non root options now for this. Another benefit of root is modding, whether through a custom ROM or a stock ROM that you flash various mods to.
I initially ran the stock ROM rooted but soon found some limitations with the sd card.
A stock based custom ROM was the solution for me ( leedroid , but there are others ) . My battery life improved greatly and some mods do genuinely enhance the experience. Most roms have an installer that allows you to select everything that's installed, including kernel .
Another advantage for me is Titanium backup, the ability to backup applications prior to updating them and restore older versions of apps .
Your choice, but I enjoy the flexibility and freedom of root to take control over how my phone runs .

Is there less development for the Pixel (than Nexus devices)?

I was surprised to notice that there is no official version of Lineage OS for the Pixel. Then looking around it just seems like there aren't that many ROMs for the Pixel. And I'm surprised to see that a year after release there still seem to be difficulties with root and using TWRP.
Am I right in perceiving that the Pixel has gotten less development interest than Nexus devices of the past? If so, why?
I ordered a Pixel 2 (to replace my Nexus 4--which has offical lineage support) and was assuming that it would get all the usual developer love that I've exeperienced in the past. Now I'm a bit worried that it will be difficult just to root it and do nandroid backups.
Thanks for any thoughts and observations.
I think they are having issues with the increased security and dual OS partitions. Will take some time.

Yeah, I saw that the dual partitions are an issue and the dm-verity check (don't quite understand what that is). But still, the Pixel has been out for a year. Nexus phones usually had tons of development by that point. I imagine if the devs were really into this phone there would be more interest. Especially the lack of official Lineage OS support, the most fundamental of all ROMs. There are unofficial versions of Lineage OS for the Pixel, so it works. I guess that's why I was starting to get the impression that the Pixel is not that popular with the devs (compared to past Nexus devices).
Price doesn't help either, I'm less likely to mess with a phone that costs a grand. Also prices it out of the hands of those that just want to tinker.
I also wonder how much baseline performance plays a role. The Pixel is really quite great out of the box, it's the first phone I've owned in recent times that I haven't had the desire to root, mod, rom, etc. custom roms are generally known to improve the end user experience, can't say that has been my experience on the Pixel and that's a big reason why I've decided stock is best for me.

For me ROMs have never been about performance, they are about features. They often have more privacy features and remove some of the pernicious behind the scenes stuff. There are more options for quick settings tiles. You can control the notification LED better. I don't want a total makeover; I'm happy with basically stock Android. But there are a lot of little things that are improvements to me. I guess this is why I especially like Lineage OS, since it is not a heavily modified OS. Also you sometimes get updates for security problems sooner (the once a month standard from Google is pretty lame--in Linux security patches are pushed out the day they are ready). As for rooting, it lets you use the iptables firewall in the Linux kernel and programs like adaway, as well as a root file manager (there are many times I find it useful to browse the system files); there is Titanium backup that is so much more powerful than any other backup tool that requires root; and a rooted device can also often get around issues with tethering. And having a custom recovery like TWRP allows nandroid backups, which have saved me from disaster so many times. So I think even on a phone like the Pixel, there's a lot to be gained from ROMs, rooting, minor mods, a custom recovery.
Anyway, I guess maybe it is just about the cost of the Pixel. Or perhaps the complexity of the dual partitions--are the Pixel phones the only ones that do this? I wonder what new phones get the most developer attention these days, if it's not the Pixels.
No, there's significantly less development, regardless of what a few users say (when I mentioned it a week ago after coming from a 6P, people were shocked when I said there's no development lol). I had to point out that 5 ROMs does not even compare to the 30 ROMs of the 6P.
At first, the pixel seemed like a downgrade to me. But after using it a week or so, it is a little smoother I got, and has better battery life, which is awesome. But those are about the only pros. Camera on mine is the same quality as the 6P, and I can't get used to the crappy downfiring speakers (last 2 devices had dual front facing).
All in all, it's an ok phone. It's about 2" taller than it should be, due to Google love affair with gigantic bezels. Haha. But sometimes using a bezeless phone one handed if tough, because your thumb can't reach the navbar.

While custom ROMs may not be about performance to you, I know that it is to others. I think there are a lot of variables at play, and I don't discount the out of the box experience as one of them. Take that custom ROMs are prone to decreased stability, especially with the Pixel and the argument for advantages of custom ROMs gets diminished fairly quickly. Unless of course you must have all the frivolous tweaks at the cost of stability and performance.

I agree, this phone is pretty hard to improve on. I'm missing all the flashing and tweaking but I'm coming to the conclusion that stock is the ticket. The stock firmware doesn't feel like a compromise anymore, it feels like it works best. With payment via phone and bank accounts on board, security is also an issue I've not worried about before but I guess I need to deal with.

I didn't say no one cares about performance. In fact, I only said that there are a lot of things ROMs do other than performance, so even if that issue is less with a phone like the Pixel, it hardly negates the many and varied reasons that people like ROMs. So I was just suggesting that reducing it all to performance as the fundamental issue, I think, oversimplifies how varied and complicated the custom ROM community of users and devs is.
Anyway, my main question in the OP wasn't really why do people like or dislike custom ROMs, nor was it do they think they are unnecessary for the Pixel. My main question was, do people think my perception is correct that devs are less interested in the Pixel than in past Nexus phones?
Personally, I believe not all developers are created equal. The pixel design and new os introduced complexities beyond the abilities of the cut and paste developer. The truly talented developers are either still hard at work or have concluded, no not worth it.
Who knows?
There are many roms out there. There are just not on xda anymore.
Development is just so much harder on the pixel, so we need to wait till the first running custom rom is out there so the other devs can pick from there. It's already been working hard on it.
Development is not so high cause a dev need the device and not every dev has the money to buy a 1000 $ device every year.
Hopefully some developers fell into some pixels when Google started giving them out as replacements for 6Ps. We'll have to wait and see.
I still suck at G+. I can't get the hang of how to search it for roms, or even how to actually get the rom, when I know a developer has one on their page. I wish Google could have tried out the service before they released it, maybe they would have noticed how difficult it can be - or maybe it's just the developers and how they organize their page...who knows.
