Is Lollipop really worth upgrading to? - Galaxy Note 4 Q&A, Help & Troubleshooting

So, Samsung finally released Lollipop for just about every Note 4 variant now but, after reading a lot of people suffering from huge battery drain, overheating and random crashes, I'm just wondering if I should bother updating to lollypop myself.
I'm still on stock 4.4.4 (with a fair amount of mods) and my phone runs exactly how I want it to. The only ever problem I have is sometimes contacts crashes, but it's not even done that for about a week.
What are the advantages (if any) of upgrading to lollipop?
Let's see if you can convince me to part with my very stable and perfectly functional modded 4.4.4.

BOC5 works perfectly fine here and is a lot smoother than any KitKat version that I used prior. If you play a lot of games then chances are you might run into the GPU bug, but other than that I see no problems in going with the newest Android version available. :good:

I got N910C. No root.
These are some facts about KK & LP according to my own experience.
KitKat 4.4.4:
Had volume spike answering bug (mentioned somewhere on XDA),
Had read only SD card problem (due to Android restrictions),
Lollipop 5.0.1:
Solved both above mentioned issues of KK,
Faster and smoother than KK,
No crashes, freezes, hickups, overheating - rock stable,
Better RAM management,
Better or equal battery consumption,
Material design (I love it, somebody else may not)
1-2 second answering ''hello hello'' bug (caller can't hear me 1-2 sec. after my answer). I don't know is anybody else has this bug,
GPU throttling bug (when phone reaches about 50 C some games stutter and benchmarks like Antutu show low results due to lower GPU frequencies)
Everything is perfect except this. This should be fixed ASAP in next update.
Be aware of this and consider eventually upgrade to Lollipop

Just in case: lots of shortcut apps (e.g. pulling down the notification bar!) don't work on Samsung's iteration of Lollipop anymore. That's still one of the biggest issues at least for me!

I have updated my UK ee phone to the German BOC3 and I have to say I'm very impressed with it. I have done a dirty flash and I haven't encountered a single issue. My battery life seems better, the system settings feel cleaner and the general visual tweaks and nice. Looking forwards to the btu

Experience with 5.01 Lollipop Update, i have had no issues with Lollipop
Lp fixed the Bluetooth stuttering bug for playing music in my car via Bluetooth.
The notifications are great and usually appropriate...
No battery crash or menu problems on Bell.

Bloody G3 - I need to rant

I know this is going to sound very much like a first world problem, but this phone is frustratingly ****. It is easily the buggiest, slowest, most laggy phone I have ever had.
I have tried just about all the LG based ROMS, only to find that each one, although not buggy, are all laggy. The lag is so bad that it gives my old S2 on Gingerbread a run for its money. At least with Samsung phones, you could get rid of the lag by using a AOSP ROM and it would still be functional.
To solve the frustrating lag issue, I have installed a CM based ROM. At first I was delighted. The lag was gone. The phone was now comparable to my super fast Nexus 5. But after a few hours, I noticed the same bugs that every other CM based ROM user has. Today, I had to restart the phone six times FFS! It is a little more stable on 777 Kernel, but the same issues still persist.
Has anyone achieved bliss with this phone? Is there any ROMS, AOSP or LG based, that are fast, (Nexus 5 fast), and bug free?
Don't get me wrong, I love devs and the work they do. Without them, my old Galaxy phones, (S1, S2, S3, S4), would have been poo. My Nexus 5 would have been boring. (Stock android is meh). I just don't understand why this phone seems to have so many issues. Help me understand why it is so hard to develop a fast and reliable ROM for this phone. I know it isn't from a lack of trying. There is heaps of support and devs working on various ROMS in the G3 threads already and all of them are very talented.
Is it hardware based lag or is there something else inherently wrong with the phone?
Thanks for reading and offering any solutions. I don't want to list the ROMS I have tried, as it will seem like I am an ungrateful twat to those devs that worked so hard. Suffice to say, I have tried all the popular CM/AOSP and LG based ROMS.
Stock 5.0 V20H fine for me no lag [emoji3]
I switched to note 4 whilst g3 was good I had a better experience with my note 3. So upgraded

I don't want to switch so soon. There has to be a solution. I love the screen and size of this phone. The only other phone I would consider is the droid turbo, but it's so bloody expensive!

Compared to what? Which other android phone have you used? In isolation, this phone is barely acceptable. Then, after you use a nexus, HTC or Sony phone, this phone is comparably slow. Almost unusable.
I can't bring myself to try stock again until someone who has other phones to base their claims on can confirm it is lag free.

Have you tried the usual tricks?
1. Swap out the stock launcher for something like Nova or Apex
2. Switch your keyboard to a 3rd party keyboard
While it does suffer from the random stutter, my phone is generally very zippy and does not lag.
Done all that. On stock based ROMS, stutter and lag is unbearable. My wife, nexus 5 user, even commented on how bad it is. I'm actually embarrassed to use the phone in front of people. I know it isn't a hardware issue, because AOSP ROMS are lag free, but not bug free.
Yeah, the phone is nowhere near as quick as a Nexus. The notification bar is also **** compared to stock Lollipop. There are a few tricks I use to improve performance on a stock rom:
1) Turn off throttling/thermal daemon via the service menu.
2) I use setCPU to set the phone to use the "performance" scheduler whenever the screen is on, locking it at 2.5Ghz.
Still isn't perfect, but it helps substantially. Obviously this is in addition to changing the launcher.
It's just one of those things. As you say, CM12 just isn't stable and worryingly seems to be going backwards, getting less and less stable with each passing nightly. The camera is also completely crap on AOSP roms. Nexus devices are great but the N5 is old and the N6 is too big and expensive. The S5 lags too, and while Note 4 is supposed to be good, but I simply won't believe that Touchwiz lag is gone without seeing it with my own eyes. Even if it has gone, Touchwiz remains the ugliest skin I've ever seen. Sony phones are nice, but they aren't packaged anywhere near as tightly as the G3, which is it's biggest strength: 22mm shorter than an iPhone 6+, with the same size screen. That's impressive. HTC's are just ridiculously large for a given screen size. The 1+1 is old now, and doesn't support all LTE bands used in the UK.
There is no perfect phone. Whichever you choose, there are compromises to be made. However IMHO the G3 strikes the best compromise available today, at least once running the latest Lollipop build and with the tweaks I mentioned above applied.
Had most 2014 flagships and G3 is deff fav so far, didnt have KK as updated to LP out the box had little lag after ota but common just needed a factory reset and all good since
Just a tip you can use on any android phone, go to settings, developer options, and set all the animations to 0.5x. This drastically reduces the time the animations take, and it gives a very snappy experience. It makes a LOT of difference, trust me.
No lag whatsoever here. Im running Chupachups newest rom with rin kernel. I've previously owned htc one, lg g2, xperia z1 and this phone definitely outperforms them all.
Ive owned the Xperia Z1, HTC One M7, and tbh id rate this better than both, i would like the battery life to be better my Z1 was amazing for that buh im custom stock rom and i dont get lag, everything is as it should be.

Because LL is still unstable and buggy? And so is any rom based on it?..
Stock firmware sucks because of LG's software - it's very badly written. Almost as bad as touchwiz is. (I used SGS3, trust me on that one...)
AOSP/CM based firmwares are better, but they still suffer due do LL newness. Wait till android 5.1, things may become better.
There is also a hardware issue: unbelievably bad heat management. They used 8974ac, but had not made any cooling system. No radiators, no heat spread throughout the case, and it's facing LCD panel - which is a very bad radiator. GG WP, throttling kick in, phone starts to lag, etc etc etc.
I think there may be problem with your unit... Try to send it back to get a replacement or have it serviced.

I agree that most of the stock LG-G3 roms, Lollipop/Kitkat, if not rooted and without any mods, LAG is unavoidable. The case is, some people can't root their phones and most of them will try searching why G3 stock rom is lagging... if I'm one of them and I happen to see this post, I would feel bad and feel stupid at the same time why I spend money buying a crappy phone.
Well anyways, try Crash Rom v2.0. It is a stock based ROM like chupachups. The animation is not as fluid as CM but I won't say that it's lagging. Compared to CM, I have not yet encountered any bugs and mostly the camera is better. If you're interested you can also downgrade the resolution to 1080p, this will enhance your g3, 3d and 2d graphics performance.
Hi im all so on lollipop 5.0 updated out of the box and its all good maybe some lag not much to notice. Still no root method yet for stock lollipop 5.0 and i dont want to downgrade to kk so il have patience and wait for new root method for me g3
Wow, I went from the nexus 5, to the htc m8, to the g3 all in year. My advice, play with this one to get the phone lag gone. This by far is the best. Like a previous person said, turn off animations and change the launcher.

Can't be an issue with the phone, as it is lag free with CM based ROMS.

I'll give crash a go this afternoon and report back. Hopefully 5.1 ROMS fix the issue too.

Already done all that. Animations are turned off, launcher animations are set to lightning fast, CPU throttling is turned off. I've tried all the tricks in the book. Fact is, LG based software is crap, just like Samsung.
So far today, the lock-screen has only frozen on me four times, which is good.
I'm not sure if I'd rather put up with a laggy phone or a buggy phone.
My phone is currently on V20h. Apart from the occasional Home launcher crash, I've not had any lag that I notice of. The last time there was any lag was on V10i. My phone is rooted but is not running any mods.
Prior to this, I've had the Note 3 and Xperia S. Compared to the G3, I would say that the smoothness is at the very least, on par with the Note 3 running on stock.
I've seen people complaining about the G3 being laggy too. Is your phone by any chance the 2 GB RAM version?
My phone is the 2gb version, but I always have at least close to 300mb free. Sometimes I have over 1gb free. Not that it should matter though, as I have read on numerous places that the 3gb version lags too, and that both phones are very close on performance. The extra 1gb of RAM is negligible.
Just flashing Crash ROM now. I think I'm going to regret it though, as I much prefer the look of AOSP anyway.
Ah crap. Just as I flash the ROM, I read that the dev is stopping support for our device. Based on the comments, it looks like a promising ROM.

Does anyone else's N910F lag?

Mine lags.
I use stock OC5 BTU rom.
I bought it second hand (just couple of months old) and it had knox triggered and with DBT OC5.
I had alexdr's OD2 multi CSC rom wasn't impressed with battery life so got customer recovery and installed deoxed rom.
Unrooted it to use banking apps.
Battery life was terrible so downgraded to KitKat BTU then updated to OC5 using kies.
I haven't done a factor reset after updating. So not sure if factory reset will help.
Battery life is still not very good but I can live with it.
Anyone also experience lags?
My Note 3 was better than this.
Yeah, mine does running SimplRom v3.2F
A lot of users have reported Lollipop lag- it just isn't well optimised for Note 4.
That being said, the one ROM that I've found has the least lag is SimplRom.
I'd recommend it if you're up for rooting etc.

factory reset can help out in a lot of cases, but stock firmware is pretty bad yes.
mostly it's because of all the junk samsung added, but also because they messed around with the runtime and some system apps (like SystemUI that causes a LOT of lag on the recents button)
Ah man. Hope they fix it. Specs are awesome and screen is amazing! But ui is full of lag and random heating up. Moto G is so much smoother
Hi!
I sometimes have recents button lag, sometimes up to 4-5 seconds.
I also experience app crashes several times a day.
Music playback (google play music is what I use) is chopping every now and then, consistently every few minutes. This is regardless of connected headset or bluetooth.
Everything feels so not optimized. I doubt Samsung has time to work on a Note 4 software update, now that they are pushing their new shiny S6 models.
Selling this and getting a LG G4.
Im not facing any types of lags or phone being heated up.Although while playing intense games it gets warmed up.Im running stock rom without root.All I did was a factory reset after the lp upgrade

I downgraded to KitKat now. Still lagging and stuttering present. Naturally had to factory reset with the downgrade. Battery life seems to be definitely better then Lollipop but still laggy as before. My phone can't be faulty can it?
My device doesn't have ANY FC. But I get TONS of lag with:
Photography (reviewing, and launching the camera)
Recent apps / multitasking
I am disappointed in the Note 4 for lags and poor camera quality in anything but superb lighting conditions.
Just might return it if Samsung doesn't fix these issues soon. I'll wait until the end of July, probably, and see if the update comes or not. If it does, and fixes, yay! If not, boo. And if it does come, and doesn't fix anything, double boo and never buying a Samsung device again. Shame on them!

Returning to Slimkat after Lollipop Impressions

I have posted and used numerous Lp5-5.1 roms with different modifications. After using them for a few months, I have decided to try Kitkat just to refresh my memory. What a pleasant surprise I got: My Z1 turned in a different device, which is faster, lighter, more fluid and virtually bugless. No overheating issues, which exist on 100% of lollipop roms. No memory leaks, no screen problems, no lagging, no freezing, no limited features...
Note that Lollipop has been around for over 6 month and there is still not one stable version. And there won't be one, as each bug fix introduces a new one. I can't blame developers: LP is simply bad in design, it can't be fixed. Art is a layer that burdens the device and is a step backwards. It burdens CPUs, hence you always have overheating and no tinkering with voltage will help. After using a web browser for 10 min (just browsing, no video), cpu temp goes up over 65 and even fixed thermanager, tweaked to not kick in until 60-65, starts to work resulting in flickering. Using camcoder for about 5 minutes results in display, the app and literally the phone shutting down, as CPU temp goes to 85-90. To fix overheating, you have to get rid of art. Art also burdens ram, while it was supposed to do the opposite. What else do you need: your phone overheats, lags, freezes, crashes, apps f/c, ram is under pressure, battery won't properly charge and none of it can be fixed in over 6 months.
Bye bye, LP, for good.

Let's hope, that these bugs also exist on nexus devices and are not device specific, so that google fixes them in Android M.
Could you tell us which kitkat bulid you are actually using?

I keep reading about these issues plaguing a lot of devices, but I simply can't share the same experiences. And believe me, I'm a power user... I'd notice.
I listen to music while downloading zips, while browsing the forums and my device stays at a comfortable temperature. And it's summer here... 30 Celsius every day at least.
Then, the touch screen freezes is something I know nothing about. Only had it once, on build 5.4.4. of RR.
The memory leak and screen light flickering is something I encounter only on stock...
I don't know what it is about my device, but I'm nothing but thrilled with lollipop.

The stock lollipop roms have driven me to root and install a custom 4.4.4 rom after sticking with stock for the first 18 months or so. Rubbish battery life, heat, redraws in action launcher. Hopefully a good lollipop will appear, and I might flash that through recovery once it's proven. Or maybe with 5.1. But returning to 4.4.4 with customisation is like night and day. Fast, cool, no redraws. Keeping a watch on 5.x
I agree all the custom 5.0.x and 5.1.1 ROMs have countless issues and bugs, heating, poor RAM management but I'd like to appreciate Sony's work with Lollipop. Sony's stock Lollipop is pretty good even for power usage. Though KitKat was definitely one of the better versions of Android. At least our stock Lollipop isn't that bad. As for me I'm going to stick to a rooted stock Lollipop until a stable AOSP ROM comes out, which will take some time, considering KitKat also took ages to fix.
I would like to see BeanStalk with shields up, like Dirty Unicorns and Slimkat :angel: Please! Slimkat is good but Beanstalk has more features.

[Q] Newest version of Lollipop or stick with KitKat?

Given all the initial reported problems with Lollipop, I've stuck with KitKat this whole time.
Now that 5.1.1 is out and it might be looking like Nexus 4 is being abandoned by Google, just wondering whether enough of the kinks have been worked out for me to upgrade, or best to stay put.
Battery life is important to me (as it is to everyone I guess), so if 5.1.1 worsens it I'd rather stick with KitKat
Would value your opinions.
I just went from Lollipop 5.1.1 back to Kit Kat just yesterday. Reason is the camera app is not reliable. If it crashes, you will have to reboot the phone to fix it. Also, occasionally, the phone will not come out of sleep... requires reboot. And I'm still encountering phone issues where I cannot hear the other party during a call, although this problem is not as frequent as I don't make/receive many phone calls.
Because I have kids, the camera app is important and needs to be reliable.
I don't know if these problems are due to conflicts with installed third party apps, but still... none of this sh!t was happening in Kit Kat... and I have the same apps installed.
I went both sides of the river here. KitKat is perfect but, its old.... And I like lollipop even though KitKat is more stable and reliable

JellyBean vs Lillipop / Stock vs Custom

First of all, this is not a childish "versus" topic to flame fanboys spirits. I just need some technical understanding of some issues.
So... I've run four or five Lollipop 5.1.1 custom ROMs on my C5303, including CM, AICP, XenonHD, Mokee. All are great and fast and developers made a tremendous job. Not all of them are so friendly with Tangerine kernel (I need a custom kernel for increasing in-calls phone volume), per instance, Mokee hangs and struggle like hell. AICP works well with T-kernel, but with some issues (reported by users), when the device will freeze for a few seconds. XenonHD loves T-kernel - no problem at all!
Still, all of these fantastic custom ROMs , with or without custom kernel, are sluggish compared with stock 4.3 Sony ROM. I've made a nandroid backup in TWRP of my XenonHD - T-Kernel installation and installed Binomical SLIM 4.3 base don stock. Just for the heck of remembering the Sony UI, I intended to restore XenonHD soon after. I'm still on Binomical 4.3. Man, this is FAST! This is a blazing rocket compared with any of the Lollipop ROMs!
On Lollipop ROMs I've had ~ 300 MB free RAM, on stock 4.3 (OK, deodexed and slim) I only have 150 MB, but Sony's ROM is way faster and smoother. It really looks like I have a completely new device in my hand. How is this possible? Why? The hardware drivers? Is X-SP really not able to handle Lollipop in a decent manner?
XDA developers worked so hard to gave us the Lollipop ROMs, and I praise their work, but looks like X-SP best choice is still the old JellyBean 4.3.
Agree.
All lollipop roms are really fast in the beginning but after sometime,it begins to lag and become slow and sluggish.I have tried many lollipop roms but always returned to stock rom.It's been 2-3 months that i'm on stock and didn't flashed any other rom.
dude flash latest cm12.1 nightly nd ull forget stock
4.1.2>4.3>5.1.1
I dont think this, i not know what version you test of aicp and xennon, thes lasts versions of aicp are laggy and xennon has battery drain sometimes, but the others no, all depends of the rom, have lollipops roms laggy and have lollipop fast roms, have kikkat laggy roms and have kitkat fast roms, and the same of all android version, the rom stock have good performance but battery drains, now i in miui 7, performance and battery are awesome
I NEVER had battery drains on stock ROM. Yes, lots of bloatware on official stock , but not battery drains. I also didn't encounter battery drain on any of the Lollipop ROM's I've tried - AICP stable and about 10 version of nightlies, CM, XenonHD latest and Mokee. Yes, those were not so "green" as stock, but nothing so horrible, maybe 10-20% less battery power than stock. The issues regarding battery were on calibration of the battery percentage, per instance it used to go downward normally till 6%, then, bang!, the telephone turned off with 0% battery all of a sudden. Anyway, this is a insignificant issue, I don't care if I'm gonna recharge battery one hour earlier, the real problem that brought me back to 4.3 stock was the PERFORMANCE.
What I can't figure out is how come 300MB free RAM Lollipop is worst than 150 MB RAM JellyBean. Why? Xperia SP can't deal with ART instructions, it's Dalvik-only? I mean, OK, our developers have limited resources and most of them test their code on their own device, they have to be careful and not trying something risky; by contrast, Sony have unlimited resources to develop and tune their ROM. I know that, it's obvious, all my respect to XDA developers. What I'm trying to figure out is what's that bump in the road, what keeps X-SP Lollipop to be blazing fast? It's ART? It's drivers? I't Tangerine kernel, that most of us "married" with LP ROM's?
Thank you guys.
To be honest, you have answered your own question based on your newer question.
It is optimisation, man. 4.3 (or prior), those stock ROMs are made by Sony. Since it is made by Sony, you can expect a very great deal out of it, battery life, performance and all of those sweet things.
Since Sony lied to SP users and abandoned the SP with the last known version 4.3, we have problems on optimising ROMs because of no official blobs to refer to.
It has been until now. Everything is, thanks to the hard work of developers, our Xperia SP can still run newer Android versions while still maintaining the "blaziness" of the ROM.
Needless to say, its optimisations.
As always, you have the rights on which ROM to use, so choose the one that suits you.
Guys, I am thinking of buying Xperia SP to use with Cyanogenmod 12.1 instead of cheap budget phone like Motorola E 4G. Price for me is the same, actually SP is cheaper than Motorola E.
I like SP because fast CPU and GPU ( Adreno 320 ! ) so it's no slouch and it has official CM12.1 support. I don't want to use anything other than latest 12.1 but I'm worried about performance and battery. Is it really that bad ?
I cannot try out the ROMs myself as I have not bought SP yet.
Is any CM12.1 ROM stable, fast and with good battery performance ? I see you have custom kernels for CM12.1 but what is the Linux version - is it 3.10 or above ?
Does SP have heating issues and performance problems ( like so many claim here ) ? Or maybe that appears only after some years of usage ?
What about this screen flickering problem which seems to be present in all CM12.1 ? How bad is it ?
Thanks for your assistance !
"Does SP have heating issues and performance problems ( like so many claim here ) ? Or maybe that appears only after some years of usage ?" It has those issues, but I think it depends on certain devices. Mine for example overheats with any rom, no matter stock or custom, while there are people who never experience those problems. As for stock vs custom it's clear enough that stock is best optimised.
I tested a lot ROMS.
I like the OMNI ROM (Android 4.4.4). It's really fast and stable. Maybe you should try it.
I like also the Xenon HD ROM (Android 5.1.1). It's fast. Not so stable, but still very good..
After a few days it gets a little laggy. I´d liked to know why to. Faced the same problem with AICP.
I've had similar experience as you guys with lollipop custom ROMS. As much as I wanted to like them, after trying few, I have switched back to stock. Lollipop roms look nice, they offer more features and battery life is amazing compared to stock. However, none of the roms are stable enough to be used as a daily driver. After few days every single one of them refused to boot up, forcing my phone into recovery mode, so the only way out was to reflash. It has been a nice experience, but XSP is my one and only phone needed for communication, not a toy, therefore I need something that works and does it reliably. I think I'd just get a nexus or motorola when it's the time to upgrade.

Guys, I am thinking of buying Xperia SP to use with Cyanogenmod 12.1 instead of cheap budget phone like Motorola E 4G. Price for me is the same, actually SP is cheaper than Motorola E.
I like SP because fast CPU and GPU ( Adreno 320 ! ) so it's no slouch and it has official CM12.1 support. I don't want to use anything other than latest 12.1 but I'm worried about performance and battery. Is it really that bad ?
I cannot try out the ROMs myself as I have not bought SP yet.

No heating issues, I mean CPU gets hot sometimes (with not regard of the ROM installed), but it's all at thigh as 60°C. Most Android devices are well in specs on that thermal level.
Performance regarded. CM Vanilla or most of the 5.1.1 custom ROM - it's fast for the day 1, then it gets little sluggish, you'll have to boot to recovery and clear dalvik/art cache to refresh you device. If you don't need kernel level modifications I recommend you to stay with stock FOTA, Tangerine kernel might cause some screen or device freeze and stutter.
Years of usage to get slower performance? LOL We're talking about hours!
Display flickering (or getting yellowish) I guess it's hardware related - some X-SP never experienced it (mine included).
OK. Thanks for your feedback guys. I cannot test myself since I don't have device.
Do you think developer support is strong enough that they will manage to get Android 6 working properly on SP ?
big dilemma
Hi guys,
I have big dilemma what to do. My wife liked to buy the XSP because of the LED lights etc. She uses the phone mostly for calling, texting and music listening. As she has the Deezer premium acc I went in big troubles with XSP because the known bad memory management. More than one year she have bothered with it(and me too . After the 2years waranty ending I have decided to root, UBL and test custom ROMs. First we have tried the lightered stock ArchXperia, which was not helping us. Now she is since August on CM12 nightly. Yes, Deezer works good now, but on the other hand she is missing the stock Sony apps, working LED bar(with music), stock FM radio and generaly dislike the 5.1 Android (she is little bit old school, not likes many new things to learn).
Please, could somebody recommend to me any rom, which is stable, close to stock look (apps incl.) and has good ram management, that Deezer will work good, without memory issues?
Was it maybe wrong, that I have skipped the 4.4.4 Android over?
Many thanks in advance for any kind of tip or idea.

Try a slim stock ROM, just as Binomical, based o stock JB 4.3. .207. It includes Williams kernel and that might do the trick with RAM management.
Yes, thank you, I was thinking about exactly this one... good to have the choice confirmed. Just installed, look forward to try it and test it on my wife

Or maybe you can check out the cm11 last build. Used to be on cm11 for a year with William's kernel and was pretty good. With some apps you can have the disco lights fully functional.
