i just traded my htc vivid for my bros samsung infuse. I loved the vivid but my bro wants it and infuse was mine in the first place. did some swapping around with my brothers. I just hate the stock rom and all the bloatwares. Can someone recomment a smooth stable rom for the infuse? also one that can tether.
Which Rom is a personal preferance.
I currently run F1 Innovation, Fast, Stable and smooth. Not sure about tethering.
F1 Innovation
Check out the super thread: Infuse Super Thread
The current miui does tethering very stable and fast. Also the battery drain seems to be fixed which is a huge plus.

Still i haven't installed it but I read that CyanogenMod 7 works flawlessly on the Infuse. I read you can use it to connect usb devices to your phone so i guess it can do pretty anything, tethering included.
The only thing that seems to work crappy is audio through bluetooth but i bet it's not a big problem : bluetooth is one of the most stupid and unsecure tecnologies ever invented.
You will find on this forum tons of informations about roms...just read it!
I have a preference for Infuse based ROM on my infuse.
they are listed in the dev section under superthread

Don't install a Samsung based rom, which is everything but CM7 or MIUI. Both CM7 and MIUI are AOSP based. MIUI is too much like iOS for my liking. I have been running CM7 on my infuse since I got it, and before that on my inspire, and before that on my captivate. CM7 is the only way to go.
For what it's worth, I'm running CM7, the newest nightly on 1/19. Very stable (some apps I had while running stock Froyo or Infused 2.2.3? would force close alot, not on CM7, but it's a very selective few apps I use for work), very smooth, very fast, overclockable to at least 1.4 gHz for most people. Some people do 1.6 gHz but it's not stable for my phone. You can undervolt it by some amounts for that extra battery savings, and it's constantly having features added to it, like T9 dialing that I discovered was included (much MUCH love for this small thing).
For all the added features, I regularly go through my phone and make sure I don't have apps that do things that are now part of the phone, so I keep the app list short and sweet. Having redundant features means that 2 things are trying to do the same thing, and I'd rather punch out my battery more and more without giving up some conveniences I had Dialer One on my phone, and it's not that great looking, but I had it just for the T9 dialing. Once I saw that CM7 had a T9 dialing feature, I uninstalled Dialer One. The music app, while not as heavy on the eye candy, made me get rid of Doubletwist and Airsync. Airsync never really worked great, for me at least.
CM7 doesn't have fully working bluetooth on the Infuse, some people have trouble with auto brightness (my personal preference is that I'd rather use the status bar slider to adjust brightness), and HDMI out doesn't work. It also has some extra niceties, such as theming, a DSP Manager app (that controls audio levels and equalizers), and is pretty much always being updated.
The drop down bar can be customized almost entirely, and because bluetooth doesn't work, not that I want it, I got rid of that icon. I replaced it with a screen timeout toggle. It has many more options than that.
One thing, and I don't think this is CM7 exclusive, is that sometimes my text messages won't send. I'm using GOSMS as my messaging app until the stock messaging app starts sending ALL of my texts. MMS relies on a data connection so I tend to pull the drop down and enable that when I want to send a picture or download one. Once it starts working the same way, I'm uninstalling GOSMS because it tends to be heavy and sometimes lags up noticeably.
I don't use bluetooth, and I don't think I've ever opened that HDMI dongle packaging, much less tried to use it. While it would be nice if they functioned, I get from day to day without even thinking about those. Your mileage may vary.
I'll throw my support behind CM7. I briefly tried ZEUS, but switched back after a couple days.

The only way to get a rom that has everything working like it should is to flash an infused based rom ...NOT an aosp rom..... cm7 is good if you don't need Bluetooth....as cm7 and miui use a different bt stack then Samsung ...so in my opinion that issue wont be fixed....and they have been known to have data issues....flash ANY of the infuse based Rome if you want complete functionality....period

Like others say if you need BT audio or HDMI stick with Samsung roms. I could care less about both, i have been bouncing back and forth between CM7 and MIUI for months now whenever there is a noteworthy update. Both are very quick and clean in my opinion and you can't go wrong with either one. I have tried most Samsung roms available but they are always short lived on my device...they always feel as if lacking something. Props to the devs for making them available though!!!
thank guys for the responses.. I am currently running the cm7.. looks great and smooth but i got a few issues maybe its the phone itself.
first: seems like my internet/wifi doesnt stay on at times or its not using wifi even tho its turned on.
second: the browser seems to be very slow and it force closes at times maybe it the site that i go to. ESPN scoreboards, i bet a lot so i check scores frequently and open a lot of pages.
third: yeah, battery does seem to go fast maybe because of the excessive use of the web.
BTW do you guys have to put in any apns?? I didnt'.
I don't think it's your phone. I'm still new at this, but as I understand it, you can make/flash tweaks and different modems that may help with the issues you encounter. Someone will correct me if I'm wrong.

I'm on cm7 and I keep going back to it everytime I flash something new. It just works the best for me. As for data issues, you need to setup the apn fix listed in n0ctrnl's compiled cm7 thread. It's in the original post I believe. Also I flashed the latest modem (uckl2) found in the sticky of development section for modems

Go to wifi settings, hit menu button and go to advanced. Under wifi sleep policy choose never. Should fix the wifi connection issues your having.
I've tried many, but Zeus is the best one that's fully functional (BT and HDMI).
if i flash the miui rom, can i just wipe data and cache than flash the rom? or do i need to do something else?
currently on cm7...
Check out Z*E*U*S ROM.

Definately Zeus for now. It's snappy, everything works and theres even a few themes as well as an ICS launcher. All the AT&T bloat has been removed. I used to prefer stock, but Zeus made me convert. It's just more responsive than any other rom for the Infuse.
It's all a matter of personal preference. I've run about 12-15 different ROMs on my Infuse so far. I keep coming back to Sensation 1.1. I really like being able to edit my status bar.
I didn't care for the camera in CM7, but it is a very nice running ROM. Only thing I miss is not having an extended power menu.
Just play with a bunch of them until you find one you like.

just download "quickboot" from the market....try it if you haven't
Every now and then my homescreens gets very sluggish and laggy, to make them turn I really need to be explicit and slow in gesturing. It seems to start at random, haven't found anything that appears to set it off.
Reebooting solves the problem, until next time of course. Getting quite annoyed with it at this point.
I have tried disabling live wallpaper and taking a look at what apparently are running, but it doesn't seems to be the problem.
It's a nexus s i9023 running 2.3.6 stock. Not rooted.
Hope there's a reply out there, thank you.

what possibly happened was you may have bunch of apps that autorun themselves when certain events occur such as when you regain network signal, receive a phone call, turn on screen, etc... over time these apps take up cpu which cause the lags you're experiencing. i would suggest rooting your phone and install Rom Toolbox or buy Autostarts app to stop some of these apps from autorunning.. The Nexus S is the easiest and most painless device to root.

I'm running almost the same apps as on my old Wildfire, and enver encountered the problem with it.
I'd prefer not to root my phone at this point. Bought just under a month ago, with the idea of running stock to see how the "pure android" experience was
I also find it hard to imagine that there isn't another way around the problem.
It just doesn't make sense to me that it takes so little to bog down the phone and that the solution is root
mine got very slow on 2.3.6 after not having done a wipe for 6-7 months. I didn't even have many apps installed. The phone runs a lot faster on ICS rooted or not.
Yeah, I've heard it should run better with ics and I'm quite tempted to just go for it with one of the many ROMs out there. Must admit I'm hoping for the official ota to arrive soon. I'd like to keep the phone unrooted so it'll recieve the official update. But if the wait proves too long I might just have to find a good ROM
Any advice for a stable no-fuzz ROM that won't cause me too many issues with stuff not working properly?
The issues with the lagging homescreens have been present in 2.3.3 as well. Was hoping 2.3.6 would fix it, but alas:-\

you can also just install advanced task killer (free on market) and kill some apps that are running and u might not need them.
Also you can try the Go lancher Ex (free on market - is a lancher that runs themes and schemes, from my experience this app make everything run smoother and faster).
Anyway like others said already custom ISC are really nice to use
cheers
Installed ADW launcher.EX and it appears to have solved the issues. Thanks for the input

After much more use with this phone and experimenting with various roms, and researching other users' experiences with ics on the galaxy nexus, I have come to the conclusion that sense is not the main culprit for the multitasking issues experienced with this phone, but that ics is. Yes sense "tweaked" the way the phone handled multitasking with the phone by making the minfree settings more aggressive, however, even after tweaking these settings with the phone, the phone's multitasking is still broken.
If you still don't believe me flash the cm9 or aokp roms and look at how the phone handles multitasking. Apps will still tend to reload after exiting them and using another app after a couple minutes. For example, while using cm9, I would have on average at least 350 mb of ram available for me to use even after having such apps like the web browser running in the background. However, if I exit the browser to go check or write emails for example for a few seconds and then go back to the browser, the pages I were viewing on the web browser resets. Look at this video for example starting around 6:20.
http://www.youtube.com/watch?v=NiRuycMN5Wg
As you can see, the web browser page reloads the same way that it does on the HOX. Even looking through other forums show the same type of reloading of apps on the galaxy nexus.
It seems that the only way to truly fix the multitasking on this phone is by changing the way ics handles multitasking altogether. Has anyone been experiencing anything different than what has been described in this post?
I don't recall having any multitasking issues on my Asus Transformer (running AOSP-based rom). Not sure I buy it as an ICS issue, but I will test some more.
Sent from my HTC One X using XDA
This has been discussed ad nauseum. I had no multitasking issues whatsoever on my GNex. Sure the browser might reload but that's it. You can leave games and come back to them an hour later and still be in the same spot. With the HOX, as soon as you leave that's it, time to start over. If it is still doing it on CM9 or AOKP it's because of the KERNEL. Pretty sure both those ROMs still use the Sense kernel or some modified version thereof.

I believe this is correct - the alpha versions of CM9 and AOKP are both still based on the HTC kernel.

Yup. This
as soon as we have custom kernels life will be much easier.
Okay, maybe someone will know the answer to this.
Every single ICS rom I've tried... and I'm pretty sure that's all of them... has had abysmal performance playing flash video through a browser. I'm talking from
jt's original ICS... to
Entropy's ICS...to
uniporn
jblparisi's
remixICS
etc. etc.
Now, just to be clear... all of those ROMs that I mentioned I thoroughly enjoy... they had/have a lot of work put into them, and I thank the devs.
But this puzzles me... I had perfect flash video playback on a number of GB roms... notably AEON... now we move to ICS... and it's incapable of doing the same thing?
Also, whatever the problem is, it is some kind of common thread that runs through every ICS release for the infuse. I've tested. There is no example of this problem not being present.
Anyone have information, or a solution, or have noticed this problem themselves?
Thanks
I do agree with your statement.
I think this is due to the Wi-Fi and data speeds. Unlike GB ROMs, build.prop has not yet been extensively looked at in ICS ROMs. Network speed drops can be expected going from GB to ICS.
Again, this is just my opinion. Do not take my word for it.
Sent from my SAMSUNG-SGH-I997 using xda premium
You have a good point there, build.prop was not something that had occurred to me.
The only thing that makes me suspicious of that particular theory is...surely all the ICS roms can't have the same build.prop settings, right? So if it was coming from there, I guess I'd be expecting to see some roms performing better or worse than others... and yet when it comes to flash video, they are pretty consistently bad, with little variation.
Thanks for the idea though, I hope that you're right and that this is just something that can be fixed by build.prop rewrites.
You do have adobe flash player installed right? Unlike gingerbread roms I don't know of an ics Rom that comes with flash player installed...when I had the infuse as soon as I installed flash player I never had a problem with flash videos...also I never had a problem with slower network speeds...

Hehehe yeah I'm not that much of a fool =P
I tested everything I'm talking about with flash player installed. ICS can't deal with the video, it sticks and sputters like a broken faucet... super choppy, stops and starts... etc.
I can't testify 100% but I'm pretty sure that my data speeds on ICS are reduced as compared to GB roms.
With Wi-Fi, however, I think the speeds are comparable.
If this was happening on a PC, I could fix it. My first thought would be video driver issues, so I would remove all traces and then install the newest version.
Unfortunately, it's not that simple on Android...
I've read tons of discussions with Entropy and others talking about the video libs, and I remember that while the idea of "perfect smooth video" sounds like something that should be easy/simple to accomplish... it's actually a pretty deep rabbit hole. It seemed to me it's a fairly complex problem that draws on a lot of areas and takes a lot of work to get right.
I just wonder what this could be... what did GB have that ICS doesn't?
thanks for the reply, mg =)

Well...ics is aosp/aokp...so it is highly likely it could be missing some video libs and what not...off the top of ky head I know for a fact that gb has TWframeworks as well as many different libs...I have no infuse to test the choppy video so when I say i never expiernced it that is just based off my memory...basically what in getting at is that your theory is possible

Is there anyone who would know how to identify the specific source of the problem?
Is there any more information I could somehow get/provide that might help?
Or is this just the kind of issue where... ICS is pretty new still, and in time it will probably be fixed? (wait & see)

Well logcats always help...those say exactly what your phone is doing and provide all errors your phone is receiving...from what I've seen, pony (the guy providing logcats for the miui build) is good with logcats...but he's busy with miui. I'm not even sure if you would find anything useful in the logcat anyway since it is somewhat working...I'm sure it will be fixed in time though
So if you know how to logcat then get one and see what it says...if not than just wait, I'm sure someone will end up working on a fix

Have you tried a factory reset? Mine was running very smoothly on the OTA. I also wiped my phone before and after the update.
Honestly I don't find it that much buttery. In some app it even seems slower. But I'm running custom ROM with some restored apps.
Maybe with a total fresh start it will work better...

Are you running OTA or some custom ROM? I tried a few different JB ROM's + kernels and wasn't very impressed. It was a very stuttery experience with lots of slowing downs. I guess i had too much junk laying around after so many flashes.
So i wiped everything, went back to stock image and got the OTA JB that way and rooted it. It's been running very smoothly ever since I wouldn't say it's a HUGE improvement over ICS..but maybe like 20% smoother. It's definitely not slower than ICS (i was running both stock ICS 4.04 and CM9 RC1 before. The only places i noticed the lack of buttery smoothness is when opening Google Now and the Camera app. The camera itself is fast and all, but the start up time is longer than i remember on ICS.
From my experience, it's actually "smoother" but not really faster than ICS.
Just went back to CM9 RC2 and I must say that it's much faster than any JB ROMs out there but just doesn't have buttery smooth animation.
I quite like JB. I don't use custom roms (I prefer stock with matr1x), and JB is nicer that ICS. Previously, recent apps was useless to me. It took forever to load. now it loads in an instant. also, I don't get ~10 seconds of lag after I install/uninstall an app, faster to boot, faster to finish loading apps after booting and the ui is much nicer. Ofc, it does stutter from time to time, but it's negligible, as far as I'm concerned. Project Butter is really doing stuff right.
Ofc, it's not as smooth and fast as on the gnex, but that's to be expected. The hw is not as good. But it does a pretty good job. I really wish google would upgrade the kernel and make it use all the ram available...don't see why they don't use it all...

Instead of pressing the search soft key just press the Google logo on the Google bar... that will bring up search faster
mine seems good
I understand your feelings, but JB on nexus s is better than ICS, maybe not faster but definitely smoother. JB does give a nicer feel to the whole phone experience.
If you're on custom rom, try the stock one Afresh. I flashed stock Ics then got JB ota. I have also used Stevens JB and oodies. But after a fresh install, the stock one seems the best. However, I'm waiting for CM10 as CM9 is definitely better than stock ICS. I'm expecting the same from CM10.

I am asking myself the same question as the op. When I got my nexus s about a year ago it replaced a horribly slow nokia n86. The new UI felt fast. With time I got used to the speed of the UI and was generally quite happy with the performance.
Then came ICS and I began to wonder. Sometimes apps took a few secons to open a certain menu, sometimes the same menu was opened in half a second. Now with JB i get the impression that these inconsistent lags are appearing even more often. A typical usecase for me:
Listening to music via BT headset -> press power -> unlock screen -> select (standard) music app -> search for a specific song.
Sometimes this works as expected with <0.5s between steps, sometimes unlocking or opening the music app takes >3 seconds.
I should note that my system is completely stock and was never unlocked or rooted. I did the OTA to ICS and now to JB as intended by google. I never whiped any cache nor did I ever reinstall. When I have the time I may try that just to see if it makes any difference. For the moment though, I am left with the impression that 512mb ram and a single core CPU are not enough for a 2012 OS.
I'm finding a big improvement over ICS. I can't say I've found anything that doesn't work at least as good as ICS and a lot of stuff works better for me. The smoothness has really improved my 'user experience'.
That being said the app developers need to play catch up and get their stuff optimized for JB.
Can't wait to try the amazing custom JB ROMs that are going to be rolling out soon as well.

Same here, I notice quite a few stutters, and I believe more than I had on ICS.
Maybe I'll try to flash stock Google ICS, and then do the official Google OTA update. The current ROM I'm using is this one, but maybe that is really not 100% the same as the Google OTA version?
Also, I'm truly disappointed at the fact that I can't use my voice on Google Now without having the whole cell phone in English. If I don't have the menus in English, all it does is Google searches... Basically seems like anyone that doesn't speak English natively is alienated.
Hopefully chainfire updates chainfire 3d opengl driver to work with jb .
Made ICS significantly smooth should do same with JB
Currently using CM10 and it works perfectly. I have not seen any lag whatsoever so i am pretty happy with it. I used the stock OTA but it was a major battery drain. That's really all I have seen that is negative.
