[Q] S4 I9505 for N00bs - Galaxy S 4 Q&A, Help & Troubleshooting

Hi Guys, ive been part of the HTC One X scene and now i am getting an s4, question is i hate Touchwiz with a passion!! so i want to use an AOSP rom, my question is what is the easiest one to use and are modded kernals a good idea with this phone? regards,

I use Danvdh's GPE ROM. It basically converts your existing S4 into a Google Play Edition S4, but with some subtle enhancements. Being a GPE ROM, it also has the advantage of using Samsung libraries for its hardware, which makes it run more smoothly than the AOSP alternatives that use reverse engineered drivers.

I had been leaning to that Rom, what about kernels any that actually make a noticeable difference? I keep seeing fast charge pop up ?

Use the Googy Max kernel that's included, or use the more up-to-date Hulk kernel variant of Googy Max. Alucard's kernel reportedly has a battery drain issue and the stock kernel introduces random reboots. As for fast charging, I've not gone through every post in that thread so if there is a fast charge option I'm not aware of it.

Is there any idiots guide to do it? Lok

An idiot's guide to install the ROM? Root, install a custom recovery (TWRP recommended here), and install the ROM through recovery. The various kernels and ROM options are all in the zip, as it uses Aroma installer.

Easiest way to root? Still on kitkat if that makes a difference

CF-Autoroot. There should be a thread for it in S4 General.

I actually find the CM12 optimzed builds to be a bit snappier than GPE. But GPE is more stable and bug free. I had several problems with the latest CM12 builds.
You can always change roms afterwards. But I keep coming back to GPE The only downside is that there is no ktoonsez kernel for GPE 5.0.
It's an awesome kernel and the only one, that I know of, to offer GPU Overclocking.
Alucard and Googy-Max kernels are great too.
Fast charge is designed for USB. The USB current is lower than the AC current. This means that the phone takes a lot longer to charge via USB.
Fast charge substitutes AC to USB. Meaning that it will charge via USB with the same current as AC.

I was thinking of the rapid charging devices like the Nexus 6 have, where you get 50% power in roughly a half hour. Glad someone around here can keep me straight.

Well, it was mainly done to increase charging speed via USB, I think.
But you can also increase the current on AC charger. Which means it charges faster, similar to what you said.
I don't know what the default is on touchwiz stock kernel, but Googy set it at 1450 mAh for AC.
Alucard kernel comes with 1900 mAh for AC. Which means it charges relatively faster. Look at it as "Overclocking" your charger
But it may also reduce the battery's life.

Googy and Hulk allow you to set the AC and USB voltages, so I left USB alone but set AC to 1900. Its unlikely that battery life will be adversely affected by ramping up the amperage of the charging circuit, unless the battery gets exceptionally hot (it doesn't) in the process. The stock charger won't be damaged by doing this as the charger is rated for 2A in the first place. Third party chargers, as long as they're rated for 2A, won't be damaged. Smaller chargers will eventually fry.

I leave it at 1450. I'm in no hurry. Especially when I'm gaming

[Q] fast charge kernel

I must be doing something wrong, but can't figure out what
I wanted to enable fast charge, cause my device drains more battery than it charges, I installed the "fast charge" app from the play store, but it always says my kernel is unsupported.
I've already tried these kernels:
-franco (franco kernel updater)
-fugumod (fugumod updater)
-trinity (trinity kernel toolkit)
-faux (fauxClock)
-timur
and I've searched in each app for a place to switch it on but couldn't find it anywhere.
I'm running cyanogenmod 10.1
the tablet is rooted and unlocked.
anyone any idea what could be the problem?
thanks for your time!
Give NCX Kernel a go, I'm nearly 100% sure (99.9999%) that has fastcharge enabled.

so far, I've been unable to find a zip with that NCX kernel, so I could flash it, can you provide me with a link or something?
I only find .img files, and I'm unsure what I have to do with them :s
Don't waste your time. If you tread the reviews, your problem is common with that app. Download Trickster Mod and use that asp.
Also, fast charge isn't going to have any effect if you're plugged into an ac outlet.

Like najaboy said, fast charge has no effect using an ac charger. Only speeds up charging if your charging via USB.

Does fast charge via USB even exist for the nexus 7, because so far this seems like some sort of vapourware joke that doesn't exist.
My device is shot, the headphone jack has gone bad, and now regardless of what I do I will always get charging from USB. It won't connect to the PC, and won't power devices from an otg cable, I even made a fast charge usb cable that tricks the device into thinking its an ac power source..... It works with everything but this, so its safe to assume that if indeed there is no fast charge I will take great pleasure in smashing this to bits.
Has to be up there with the first generation Xbox 360 as one of the worst build quality devices ever made.

And even then only if the active USB device (e.g. powered hub) is also designed to not current clamp or fault-open at currents above 500 mA. It takes two to tango.
Even when it does work, it's nowhere near as fast as a 2A AC adapter, btw.
USB 3 can output 900mA

Any change to resolve this issue?
I have a 2A usb car charger, but is I use GPS programs (like waze) , battery drain in too high , and charging current is not enough.
Any Fast Charge supporting kernel could be the solution.
It worked very well in my previous Galaxy Nexus phone.
Any idea?

A kernel with fast charge is inapplicable to your situation. You simply need ausb cable that had the d+ and d- pins shorted.

Does G2 accept Quick Charge 1.0/2.0?

The G2 seems to be capable of using Quick Charge 2.0, which is part of the Snapdragon 801 chipset. But with mine I got a basic AC wall charger, and if you read the (literally) microscopic text on it, it says it's putting out only 1.1 amps... which is well short of the at least 2 to 5 amps of many other chargers. So my questions are this:
1. Did anyone else get a higher capacity charger with their retail kit? Mine is a long rectangle bearing the LG logo.
2. If not, is this stock charger really not compatible with Quick Charge 2.0, or am I just reading the fine print wrong?
I've been researching this further, and it may be that LG intentionally shipped a low amperage charger. Because the battery is not user-serviceable, it would behoove them to use a slower charger, since ultra-fast charging harmful to the its life and capacity. The intricacies of rechargeable batteries are many, but the excess heat generated during charging degrades a Li-Ion pack pretty quickly, among other things.
Still, based on the assumption that the stock charger is truly 1.1A, I just bought a QC2 charger -- when I'm out in the field, I don't have time to sit and wait for something to charge at an outlet. I also bought a 10000mAh external battery with a solar panel. The rate at which LP eats juice is no joke.
@voxluna the g2 is using an Snapdragon 800 chipset and it might be capable of doing it but I don't know about it. But the micro usb port also doesn't support it as the additional pins were highlikely for slimport. Also using quickcharge on a device like this is highly risky as the device might not handle it too well. If the stock drains too much I suggest to find the cause of the problem and kill it or use an good custom rom with an good kernel and remove apps you aren't using. Goodluck.

I will dig into the QC2 wiring plan, just out of curiosity. I am confused as to whether an extra USB 3.0 port/pins are necessary (like on the Note 3) or not. Though I believe that plugging a phone into a higher amperage device is not supposed to be harmful. It's too late to cancel the Amazon order, so we'll see.
What I don't know is if my 1.1A charger is what's standard with a retail G2. The reason I asked if anyone else got a different charger is that this phone was a refurb I got from T-Mobile. For example, it came with a cable that I don't think is OEM LG, because it doesn't work with ADB. OTOH, it is possible they just don't implement QC2, like most models don't have the FM radio capability. But, the radio is omitted because carriers don't want it competing with music downloads; as for faster charging, I can't think of a good reason you wouldn't offer that feature.
@wulsic After a little digging, it appears you don't need any extra pins like on the Note 3; a sync+charge cable will suffice. And that makes sense, because the QC2 standard applies all the way from Snapdragon 200s to 8xx. Nonetheless, so far I haven't seen any documentation saying the G2 compatible with 2.0 -- the single LG device listed by Qualcomm is a G4. Crazy, really.
That still leaves QC 1.0, but I have yet find anything that shows the G2 (however, Qualcomm's listing is dated from before the phone came out, so it's not definitive). It may also be that a plain 2A charger, which I do have, can do the job faster than this LG 1.1A. I'll have to do some accurate testing to quantify a difference.
Further research: I came across this thread, a post in which seems to indicate that the G2 can do fast charging. However, I'm having a problem with the current not showing up properly in monitoring apps, which is confounding this entire process.

[Q] D802 Lollipop Slow charging

Hi friends
My device
there is the problem of slow charging
The current value 304-500maH
I tried all versions. V30a,V30b,v30c,v30d,v30e,v30f all the same problem
All transactions did. Wipe data factory and wipe cache :/
Thanks...

Hello friend, whenever you plug your device in USB port or a less powerful charger, it will show as slow charging. Use a 1.8A, 2.0A or more output charger to charge your phone.

Kitkat 4.4.2 no problem 1610 mah
Just lollipop problem
Hi,
I have the exact same problem. I recently upgraded my LG G2 (EU version - Dutch) from KitKat to Lollipop (5.0.2).
My car charger and wall charger (both 2.1A) were able to charge my G2 in a fast way under KitKat.
But now under Lollipop, these chargers have become useless (they charge very very slow).
My battery is draining while using GPS and media streaming in my car with car charger attached (whereas with KitKat everything worked fine, and my battery gained extra power...)
Only the official LG OEM charger can charge my phone fast.
How can I fix this? Somehow LG verifies if the official charger is attached, and otherwise he limits the charging?
I hope you guys can help me out?
Thx in advance!
Possibly a temperature issue

Few days ago i was exactly in your shoes. I came from a custom rom (cloudy g2 2.2 with dorimanx kernel ) to the stock lollipop 5.0.2 . While being on the lollipop rom the device could not hold a charging rate above the 350-400 mah. Through some testing i found out that device needs to be below a certain temperature (for me at least, it was around 60 degrees celsius ) in order to charge at a 1600 mah rate.
I have tested some stuff during the weekend, but in my case, it isn’t temperature related. Even when the battery temp is low, the 2.1A charger still charfes very slow, while the OEM chargers goes full speed. So battery temp doesn’t affect my charging speeds.
Even during the hot summer days, my car charger was able to charge quickly while using KitKat.

Nothing that was posted on this thread is correct, lg's lollipop kernel is horrible and only slow charges. Thats why Dorimanx when build his kernel had to add a feature that allows fast charging.

I read somewhere that from the lollipop version of android and onwards , a certain " code " has been implemented in the stock kernel (and as result every stock based kernel out there) , that checks whether or not the original charger is being used or not. Might be false, might be true ? who knows? i only have the original charge so i cannot test it out. On the other hand, many custom kernel developers including Dorimanx as @Eminemiero says do actually have a workaround implemented on their kernels to give the possibility to achieve full charging rate even on 3rd party chargers

same issue.
try dorimanx latest kernel. If you are not a fan of custom kernels, then just install it and dont touch nothing on its settings
Try Llama sweet kernel.
Install synapse from play store.
Install UKM zip from recovery . find in main kernel thread.
Open synapse go to misc . enable fast charge . set it to 1200 Mah . you are done
Don't forget to nandroid backup before.
I'm a n00b when it comes to flashing custom roms, custom kernels etc (never did it before).
What is the easiest way for me to achieve the fast charging back on my LG G2 device with the other chargers?
Maybe some step by step instructions?
Can you use an alternative kernel on the original LG stock rom? I'm happy with the stock rom, except for the charging issue i'm facing...
many thanks!!

Low charging current on i9505, CM12.1 SABERMOD

So.. my s4 with CM12.1 SABERMOD(oct 15) has low charging current, 760 Ma.
My question is: Can i change it the charging voltage, if the kernel doens't support STweaks to change it from battery AC Charge current setting, like i do from others roms ?

You can change charging voltage but it must be an kernel that's supports changing Voltage for example: alcurd kernel, hulk kernel(an brand new kernel),etc.

Afaik, I didn't include it in my kernel. Was the current always low like this? And have you experienced higher currents on my ROM before? You should also try different combinations of chargers and USB cables to make sure either of those aren't bad.

Sounds like your charger is duff. Too many fakes on eBay I found. Get them from Amazon, fulfilled by Amazon. Also need a decent cable, they can be rubbish on eBay too. I went to JuicEBitz for mine.
Also check phone status, make sure it states AC and not USB
I also think it's the charger.

Real story: i was running prev version of saber (SaberModCM12.1-20151005) + Fly on mode and i had about 1000Ma, then i suggested my friend also with same phone to install saber(SaberModCM12.1-20151015) without Fly on mode, and he had 700Ma, after cause i had some lag cause of Fly on mode, and because i wanted to up my rom to lasted version i installed it (SaberModCM12.1-20151024-jflte-ecb6003d89-GCC4.9) and i had 700Ma too
I also tried another charger, and another outlet, same...
It's somehow annoying because the phone is charging slow, too slow, when i'm using it sometimes it just didn't charge it's go lower ...

G530R4, how to enable fast charging w/ rooted stock 5.1.1 ROM and maybe overclocking?

Hi,
I have a rooted G530R4 Grand Prime with latest stock 5.1.1 ROM. I would like to know the easiest way to enable fast charge support, all the APK app's require a "modded Kernel". I am not familiar with Linux but I am an ex IT professional who learned MS-DOS back when Windows 3.11 was the latest and greatest so command line doesn't scare me.
I would also be interested in enabling overclocking past 1190mhz but this is of virtually no practical use to me whereas a 2.1amp fast charge capability is of great practical benefit.
The Grand Prime comes with a 2600mah battery so using the conservative rule of "1C" (charge amperage being equal to capacity in amp-hour) using a 2.1amp charge current should be well within lithium ion/polymer safety margins.
****Some new advanced high current specialty lithium polymer batteries can safely be charged at 8C (that's 1/8th of an hour to fully charge) but don't get any ideas on smartphone batteries as smartphones have an extremely low discharge rate whereas high current applications often require batteries designed to be discharged in as little as 2 minutes, such as in performance radio controlled airplanes. It is unlikely for a high current capable battery to be marketed for a smartphone.
Anyone know how to help me with this fast-charge thing? I would really like to enable this feature, chipset supports it on the HW level.
