[Sprint Samsung Galaxy S 4 General] LAYGO:
Yesterday, we moved into a new office building, no wifi, and I get REALLY ****ty 3G connection. It's KILLING my battery . . . bigtime. I just called the number from the Airave site & they're telling me I have to pay for the government local/state/federal taxes, but nothing for the device or service.

http://now.sprint.com/airave

They also need to know who the internet provider here is at the office & that they have some providers that they are not compatible with.
[Sprint Samsung Galaxy S 4 General] eskomo:
I've had one of these since 2010. I got it when I was in Ohio for 2 years as Ohio has horrible service all over the state for all carriers. Anyway it worked ok for calls while in the hose but once you hope in the car and drive away while on the phone it would drop the call. Sending txts would cause the other person to receive 10-20 of the same txt over and over. My girlfriend at the time got 73 of the same txt over a 30 minute period.

I've heard some people say they fixed this with updates and things but Ive also heard others say the updates didn't do anything to fix it.

ATT has had this for a long time as well. They use to have to send them out when they were still the only ones with the iphone and no one could get signal on that horrible network. My cousin had one.

So P1NK13P13, take it from a fellow Michigander... They do work, but they are known for their issues. Hold tight cause that Westland tower is going full throttle soon. If you live 7-10 miles from it you should be ok on 4G. :)

Google voice calls are not using data, they are using the cdma connection, but instead of connecting directly to your other party, Google is in the middle making the connection.
[Sprint Samsung Galaxy S 4 General] swalker23:
That is true but there is a work around. You can use Groove IP, which I use at home, with your google voice and it will not use your minutes. Instead it uses data from over your wifi connection. You can also use another app called Talkatone but I prefer Groove IP. I have to go this route because I'm just right outside of sprint coverage area in my home and could not receive the device because I'm not in the coverage area.
[Sprint Samsung Galaxy S 4 General] SirCumference:
I was having terrible signal quality in my home, on one long call I must have had three dropped calls! Thankfully, I live in the Chicago area where Sprint just bough out US Cellular services in the region, now I'm at least getting 3G in my house if not 4G.
[Sprint Samsung Galaxy S 4 General] tenaciousj:
I got a Airave 2.5 after my 2.0 died. Getting slow data speeds on 3G with it, around 100-300k download. Anyone else having this issue? I do have mine setup behind the router being my previous one slowed down desktop speeds with it hooked directly to the modem.

I did find that switching network mode from LTE/CDMA to automatic made it faster, 2.2mbps down and 700k up.
[Sprint Samsung Galaxy S 4 General] miketucky350:
I got mine free of charge a year ago and I was impressed that I had full bars on my e4gt. It always failed text. On top it uses 1.8mbps for data so its not using sprints data its pushing people off towers to your wifi. Which is ok but for people with dsl and not cable its a huge problem as that will take up most of their speeds. Plus the way they want you to hook your modem in to it and run your router from it it!! Youtube dont work and its awful. Always run router first and airave off router. This thing is a massive bottleneck for true high speed cable or fiber internet. It just cant kick out the speeds your modem makes. For most people that dont know better and follow directions it would cause major frustration. Im glad that sprint loves east central indiana and every tower has network vision sites done and 4g lte is all over. The airvanna wont connect to my gs4? I plugged it in for ****s and giggles and no go. Anyone else have this issue?.
[Sprint Samsung Galaxy S 4 General] dreDrennon1:
I used to work for sprint this had been around for several years they don't tell people because they don't want to give them away you can buy them on their website for about 130.00 and then you have to add a line specifically for this and there is a 25.00 monthly fee but if you can prove that you don't have adequate coverage they can and sometimes will send them for free with no monthly charge I just had one Sent to me today it should be here in a day or so

It is not just sprint here no phones work well in my neighborhood there are over 3000 houses in my subdivision and one sprint tower one Verizon tower and one att tower to handle all of these devices over here and we are surrounded on 3 sides by a lake
[Sprint Samsung Galaxy S 4 General] neemot:
I have one and I like it. I have decent service outside of my home especially now that Network Vision and our LTE Buildout has begun. But I live I a huge brick house. Before the airrave I had no service and went into roaming to make a call now I have 5 bars and a -79dbm and life is good. #personaltestimonial :)
[Sprint Samsung Galaxy S 4 General] zadane:
There are a few ways to get an airave free.

If the number in the OP denies you; call into acc services and ask for one.

If acc services denies you, call in to tech ( better chance with mobile broad band tech) and ask for it

Im a spribt employee and was even told i have to purchase one. On top of that there is a $25 monthly fee. So employee care got a nice little emaio frok me and hopefully they takr care of it.
[Sprint Samsung Galaxy S 4 General] dreDrennon1:
I received my airave today after speaking with customer care found out the store rep had lied to me about ordering it for me the care rep transferred me to the loyalty tram after they reviewed the notes on my account and verified the actual coverage at my home was poor on their coverage map they said I qualified for a free airave with free monthly service all I have to pay is like 3.00 a month for the government fees for the line it was dropped off about an hour ago I plugged it up after a few minutes if letting it settle in on my home network I have full signal here are a before and after screenshot comparison
[Sprint Samsung Galaxy S 4 General] wkbrdr403:
Do you have to pay per month or can you get it free I get 0 to 1 bar in my house.
[Sprint Samsung Galaxy S 4 General] neemot:
Its free but you have to pay government fees on the line.
[Sprint Samsung Galaxy S 4 General] wkbrdr403:
one time fee? or per month? how much?
[Sprint Samsung Galaxy S 4 General] neemot:
Its about 3 bucks a month
[Sprint Samsung Galaxy S 4 General] daniel4653:

Download links and changelog

If you have rotation problems try this (thanks to bilgerryan): http://db.tt/b6GG7eU1

If you use TWRP, you may have to fix root perms before you reboot...

ATTENTION

: I am only updating the smdk4412 (new kernel) at this time. I believe most ROM devs have updated thier sources to use the smdk4412

If your ROM isn't yet compatibile with the new kernel, first talk to your ROM dev. If you ROM dev is not willing or unable to update

then let me know, and I will try to make the time to configure my sources for compiling the smdk4210 and update it. Otherwise, you

will have to wait till I can get to it.

smdk4412_p4.zip New kernel (link coming soon)

p_4

Added phase 1 thru 3.1 from old kernel

Bumped to 4.

cherry-picked from AGAT_GB27_kernel. Thanks agat63!

Added OC to 1.6

Added UV

Edited bus frequencies and a whole bunch more

Voltage Control app still not working properly, but well enough...lol (I'm still working on it)

smdk4210 Old kernel

p_3.1

Bumped to 3.1.

Added lionheart governor.

Fixed smartass2 governor.

Added vr-ioscheduler.

p_3

Bumped to phase 3.

Added hypervTNT (with phase 2 and 3 stepping) and smartass2 governors.

Working on voltage control app compatibility

E4GT_p2.zip

Bump to phase 2

Minor adjustments on system control values

Added Xan's Voltage Control App (This will come in to play very soon)

E4GT_p1.1.zip

Introduction of Lightning Zap!

Known bug. This might goober up gapps. So, be aware you might have to reinstall gapps. I'm working on it now...
[Samsung Epic 4G Touch] thomas.raines:
More tips and tricks

The governor tweak is set for a fairly balance of performance and battery life. If you find yourself needing battery life over performance, you can make some minor changes. Here's how:

1 Download Script Manager from the market (it's free)

2 Open Script Manager and navigate to /system/etc/init.d

3 Press menu/more/advanced options and select mount as RW

4 Select 01governor and select "edit" at the top (this will open the file in a text editor)

5 Uncomment (remove # in the particular line) and change:

echo "45" > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold;

To:

echo "[COLOR=red]70[/COLOR]" > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold;

Only change values in increments of 5 for the up_threshold.

6 Select menu/save

7 Press the skull and cross bones icon at the top (this will allow Super User)

8 Press run, close app and enjoy

This will result is slightly slower performance but higher battery life.

When running in a higher performance mode (especially for gaming) you can disable powersave_bias by changing the 1 to a 0 like this:

echo "1" > /sys/devices/system/cpu/cpufreq/ondemand/powersave_bias;
echo "[COLOR=red]0[/COLOR]" > /sys/devices/system/cpu/cpufreq/ondemand/powersave_bias;

Powersave_bias only allows the CPU to peak for small increments at a time, and not allow the CPU to remain peaked even when the system calls for it. In gaming, that could result in choppy, laggy perofrmance and slow FPS..

This is now controlled by the kernel. You can still change the values, but be careful as too low can result in camera and graphics issue and too high can seriously drain your battery

Changing the sampling rate controls smoothness and responsiveness. I set 150000 as default

echo "[COLOR=Red]150000[/COLOR]" > /sys/devices/system/cpu/cpufreq/ondemand/sampling_rate;

I am not responsible if you do something wrong. Make a back up just in case.
[Samsung Epic 4G Touch] thomas.raines:
How to incorporate LZ kernel into your ROM.

First you would add the kernel and vendor files to your manifest, then repo sync. I'm not going to tell you how to do this because I think if you are compiling a ROM you probably already know how. If not, let me know, and I'll post that up to.

Then, in device/samsung/d710/d710.mk add:

# Adding Lightning Zap! vendor files
$(call inherit-product-if-exists, vendor/lz-kernel/E4GT/lightningzap.mk)

Then compile as normal, and you will have the complete Lightning Zap! kernel package.

its a pretty bad ass kernel man im loving it
[Samsung Epic 4G Touch] ktempleton:
To start the on demand gov is set as the default gov and is the one that is optimized for the kernel...

You can play around with the govs but keep that in mind

Also as far as tweaks go you shouldn't use any because they could mess things up.. If you do use them and have problems please don't waste my nor Thomas time until you reflash the kernel to remove the scripts and verify that the problem is the kernel thanks:cool:

Thank you TR and KT. Im all over it
[Samsung Epic 4G Touch] Warboy:
http://xdaforums.com/showthread.php?t=1530147

Ask AGAT about making sure the kernel is Extweak compatible once you get to that phase. It allows CPU/GPU Overclocking, OV/UV, etc ,etc. You can sample it using GB27+AGAT's Custom Kernel, but it isn't saving the settings right now on GB27.
[Samsung Epic 4G Touch] mkfryan:
Awesome work. Possible bug when screen rotates to landscape it won't go back to portrait workout turning phone upside down then as fast as I can flip the phone otherwise it goes back to landscape, locking and unlocking screen also fixes, more of a work around. Running pac.

I know it's still early and remember I flashed the new one a little bit ago so that took 10 percent off the top

Running beanstalk And rotate is working....maybe a PAC thing...I was running PAC earlier and in landscape it would soft boot...no idea if that's related but on b stalk landscape returns.
[Samsung Epic 4G Touch] asd87:
Not trying to be negative here but I haven't noticed any difference with this kernel. Battery drains the same, network speeds are still the same (slow with AOSP ROMs) and I still get a little bit of lag when multi tasking.

For you goo stalkers..lol

Phase 3 is not yet complete. I have added a modded hyper governor (HypervTNT) and smartass2 thus far. Unfortunately, smartass2 isn't done yet, and I will be adding a couple more governors as well as some other good sauces like better undervolt code for use with Xan's Voltage Control app.

I'm hoping to have it done by this weekend for you guys, then I'm taking a small break to work on another project with the rest of my team...

[Samsung Epic 4G Touch] GrimeSyndicate:
Well, I dirty flashed this over the 1.1 kernel and Domination's latest build. As far as I can tell, everything seems to be working well, and quite smooth to boot. Now, TR, I've got a question for you. When you've just flashed the kernel and are booting up for the first time, what exactly is meant by the "wait for ten minutes" instruction on the OP? The reason I ask is that as soon as the phone booted up (1st time after flashing the kernel) I had a phone call come through ......or maybe it was a text??? Either way, an event occurred which caused me to use the phone a fair bit inside of that ten minute window. Does this mean my dalvik cache didn't have a chance to fully rebuild properly? Should I flash it again (and again and again if necessary) until I am able to get a full ten minutes of no activity, or is this nothing to be concerned with? Thanks in advance...

-G.S.

---------- Post added at 11:12 AM ---------- Previous post was at 11:10 AM ----------

Or is it possible to just wipe dalvik to achieve the same effect? Seems a likely solution, but I'd like to hear your opinion on the matter before I take any action of recourse. Thx again
