Aosp ROMs and LTE. - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Cm10.1 on my s3 is awesome but it makes the device have connectivity issues (wireless radio performance is cut quite noticeably.).
Can anyone tell me if the s4's AOSP ROMs have this issue? Is Touchwiz a better experience as far as 3g/4g go?
Thanks, might get this phone soon and jist seeing if I'll run into this again.

[Q] Upgrading to GS4 from Epic 4G Touch? (GS2)

Hey Everyone,
Okay.. getting ready to upgrade my GS2 to GS4, but have a couple of quick questions.
1. I read that the GS4 was laggy when it first came out. Has Sprint fixed that in the stock ROM? Or does sac's rom fix it?
2. I read remember reading something about a camera issue on the purple GS4. Is there still an issue with that?
Thanks,
EB
It's kinda laggy still with the latest official rom. Many people might disagree with that statement. The more apps you install, the more lag it gets. My opinion is, the biggest improvement you will notice is the screen size and much higher resolution. If you have 4g LTE in your area, you should notice much higher online speeds when compared to 4g wimax. Other than that, IMO, the other improvements are negligible. A stock battery will last longer on a s4 than the s2. I've only ran stock roms so I can't give you any opinions on them.
No lag on this phone but when I try different kernels I sometime get lag but when I go back to stock kernel I have no issuses. That's my experience with this phone I came from the s3

NO lag whatsoever for me. My phone is ripping fast. Have unbelieveable GPS (which I sorely lackes on my Epic 4GT). Have stupendous LTE (when I get it) and everything just works.
I have tried most of the ROMs here (Sac's and Triforce are great!). But I need my phone to 100% funtional for work so I'm usually on a stock (or slightly modded) TW ROM.
While my battery life is great (often over 24hours with about 50% of that screen time), I am not a battery life thumper - it's 2013 folks and you have a $500+ device; buy another damn charger or battery. I prefer stability, speed and smoothness; in that order.
There are a few really polished TW ROMs here and also some AOSP/CM variants that are really comming along. My only issues with the latter have been problems with GPS and sometimes even data - both of which I rely on heavily during my work days.
This phone, being a sammy is very similar to the e4gt. If you spend some time going through all the posts you will very quickly pick up on some of the differences. Biggest being that on this device the boot, recovery and kernal are all seperate images. So you kernel doesn't have to be 'wrapped' in a recovery, you can mix and match to your liking.
Jump in and have some fun.
Good luck.

I recently made the same upgrade you're considering. While I loved my old E4GT the improvements in the GS4 are amazing and I love it. With that said it's not without it's issues, the lag you spoke of earlier is there sometimes it's not unbearable, but I definitely feel like Touchwiz is holding the hardware back (nothing the official CM wont fix!) battery life is fantastic, especially with Sacs rom. I get 20+ hours on a full charge, with heavy use it's more like <15. GPS locks fast, much faster than the Epic Touch and the screen is light years better.
I do notice this phone gets quite a bit warmer during regular use than the E4GT (which barely got warm, except for specific situations) but it's much better with Sacs rom than on stock.
All and all, you'll be happy with the upgrade and will not regret it.
Thanks for the info guys. I wiped my E4GT and put a tweaked stock on it (was CM10) and it actually fixed the GPS issues.. but now the phone reboots itself all the time and freezes and completely freaks out when i plug in my car charger... lol.. So this is a good excuse to upgrade..

I upgraded from an S2 to the S4 at the beginning of the summer. I mostly ran CM/AOKP based ROMS (usually BeanStalk or one of it's variants) on my S2, but after reading so many positive comments on the S4 forum about TW/Stock performance, I held off on flashing CM/AOKP and have been a very happy camper running Highway55's MF9 TW-based rom which I highly recommend (see my detailed post on the Highway55 rom thread that describes my basic configuration).
I don't notice any lag, and battery life has remarkably been improved over the S2. I hate to be tethered, so I always buy an extra battery. With my S2, I would swap my battery two or three times a day (I'm a heavy user), but with S4's remarkably improved battery peformance, I swap my battery maybe once or twice a week. GPS just works period. LTE is amazingly fast. This phone rocks!

WiFi usage

Hey there Xda people.
I dont know if this was already answered (i searched and found nothing). Why the WiFi signal is poor on EVERY custom rom?. I know that the developers makes its best with his custom roms and I love that, but why the WiFi is horrible in custom roms that in stock?
I've actually experienced significant better WiFi reception on CM10.1 than on Stock 4.1.2
EX. With CM, I'm able to receive a signal on my deck, with good speeds as well, while I simply cannot receive a signal on stock.
Does anyone else experience this?

One of the updates that Verizon made to Stock was increase the range of the Wifi. Maybe you didnt install that update while using stock.
The reason stock runs better... Well... Sometimes runs better... Is because the kernel is being developed by people with more inside access than any custom ROM dev could ever have (with the exception of that whole Oppo+CM thing...), and they're getting paid to work 8 hours a day to develop it well. Since the ROM devs don't have access to the inside kernel data, they basically have to make a graceful hack. Which sometimes doesn't work well. FWIW, I have perfectly fine WiFi access on custom ROMs, not enough of a difference to notice.

My WiFi has been better on 4.3 over stock. Gaming is a huge improvement over stock. I will never go back.

cm12.1 vs stock performance

Hello. I'm going to change my OPO because of it is too big and touchscreen issue drives me crazy.
I'm just curious if cm12.1 is better than stock ROM for s5.
I've herd that there is no official Samsung's kernel source support, so custom ROMs are garbage.
It that true? I love CM, and I want my future phone to run CM smoothly as nexuses or 1+1.
What about camera cm vs stock? Is battery good on cm12/12.1?
My experience: ROM is flying compared to stock. Everything is faster and smoother.
Yet I choose to use a stock based ROM (themed to look like AOSP). Primarily because bluetooth audio streaming stutters.
Cm camera is OK, but stock is much better.
In my experience battery is more or less the same.

Is cm12.1 stable enough for daily usage? Are there any other issues with BT, WiFi, GPS?
Well, cm12.1 has enough bugs, GPS not working, Bluetooth can crash, also less features. I installed it mostly because it is now based on android 5.1.1, which has working WiFi, and Samsung ROM is 5.0, buggy as hell, plus they will not release updates till Christmas. Anyway, s6 ROM 5.1.1 is in testing, and when it will be released, it will be ported to s5, so I will install it.
GPS crashes in my s5 never,Bluetooth headset stutters a little bit but it can be fixed with Bluetooth patcher.
I would say Samsung stock Roms are definitievly better but cm 12.1 is also good and it has started just a few month ago,so waiting is the best choice you could do

Hello, I'm curious. What is the Bluetooth patcher you're talking about?
I've search with no descent results.
Thank you
It's called BT Patcher and it is needed for Ant + products to Connecticut Thema with your device.
Ant + products are things like smart watch ...etc
I dont know if the BT patcher is necassery for headset but you could test it ,it seems for me like if it makes the stuttering lower

Need to try out roms which actually work with my damn phone! (G900I)

I've been pretty frustrated lately, this stock touchwiz ui is so full on crappy bloatware that it consumes 70% of my ram, even though the full ram is only at 1.67GB, whatever rom I try either the nfc doesn't work or the phone stays very hot and drains the battery quickly!
Can anyone help out on a good rom my S5 G900I?
Help is greatly appreciated.
TIA!

I wouldn't look too much at numbers like RAM and cpu speed. I always ask myself: does it lag? how long does it last? . S5 seems to do ok with those questions even with stock ROM IMHO. Root + right apps/ mods and debloat should boost that even more.
Custom ROMs are always better of course. our G900I unfortunately misses out on the main development scene on XDA with 900F being the global version. Many of these ROMs actually run pretty well on 900I (my fav being phoenix ROM) but as you said the problem with these is that NFC don't work.
There was really only one ROM that I have tried that has been fully functional: Xtrestolite (touchwiz based) is excellent and light while having all features. The only con is that it is a lollipop ROM and few mods. especially theming i found lacking.
In theory omega ROM (touchwiz based) should be good too, but I've never tried. The old lollipop version supports 900I.
Alliance ROM (touchwiz based) looks good too in theory. I could never get it working well with the theming though... but never spent too much time with it. Alot of the mods seemed to rely on a cloud/data base that has been taken down.
Ressurection remix I found great. Every thing works fine. Battery to me is about the same. Its fast. Plenty of mods, theming and features. It is AOSP based. After a fair bit of use, I realised 2 things that differed: 1. camera sucks more 2. can't video call through the calling app. Everything else is just as good or better i reckon. Substratum themes = awesome. I'm currently on RR 5.8.5. It is Nougat 7.1.x . There is also an oreo version of RR but there are no custom kernels for oreo AOSP roms for our device so I'm sticking to nougat for now.
If any further questions or help required, ask away.
edit - there is a smartpack kernel for G900I/ kltedv oreo. However NFC doesnt seem to be working on it and I found oreo RR lacking in performance, stability and features compared with the Nougat versions. It is only in beta, so hopefully this will be ironed out in the near future.

LineageOS is officially supported for your device with android 7.1 Nougat. I dont have that specific model but ive never had problems with that os on my s5.

AOSP users, what do you missed the most from stock ROM?

Camera quality is capped at 1080p Samsung won't release its source code.
Volte is not working because no release source code.
I think that's it. Lte internet still works.
GPS module does not work as it the GPS hardware you can still trace location using internet on the phone.
High Camery Quality
True AOD
High Performance, my Benchmark Scores are way lower and it lags a litte bit on AOSP vs stock Rom.
Don't use any AOSP rom, still using the stock rom.
I always encounter many more issues on AOSP roms and don't really ever get to fix them/sort them out, so I usually revert back to touchwiz quickly.
My notifications for apps such as gmail and WhatsApp end up not coming through unless I load up the app even when tampering with battery optimisation etc. I've always suspected the kernel to be the cause of the issue but I don't know enough about how that all works.
I was wondering maybe one of you guys had an idea/template for the best settings/build/set up for when using an AOSP roms such as LOS, BOOTLEGGERS or RR cause I really wanna use them but notifications are important to me
