[Q] technical questions - MHL/USB, bluetooth, data thruput - Galaxy Note 4 Q&A, Help & Troubleshooting

Longtime lurker firstime poster.....note 2014 owner and perhaps soon to be note 4 owner.
I want to possibly get in on some development but before I get seriously invested in both time and money Im doing some fact finding and im hoping to crowd source some data from anyone who wants to help. Here are some questions im exploring...
1. MHL max data throughput and from which sources/channels....for example what differences are there between raw USB data transfer, HD video, audio over USB/MHL, etc....im looking for max supported throughput figures dependent upon type of data and sources or inputs.......would also like to know what mainboard bus speeds for MHL are supported versus real world speeds.
2. Are there any high detail mainboard and related circuitry diagrams available anywhere online
3. Bluetooth. What is max throughput, response time and max number of simultaneous device pairings allowed and the max throughput or transfer speeds for each individually if there is just one device, two, three or more....in other words how is speed degraded for each device added and so forth
4. what are the max number and type of ports the MHL interface will support with and without external power and how is speed distributed tomeach of the other interfaces (for example a port replicator type of device)
thats all i can think of right now thanks for your time

Vibrant keeps dropping N for G!

Okay this is a HUGE a huge disappointment to me. I have a Netgear b/g/n router and it seems to drop the N connection (where I get 3/4 bars) and return to the g connection (1/4 bars) and limits speeds to 5mbps. Please tell me I am not the only one with this problem and that it will be fixed. I know I've not heard this problem before...
P.s. I am sitting in the same room with my Xbox Slim and it maintains n the whole time, so no, I don't think its my router...
Wow. Almost 50 views and no comments. I wonder if it's just mine. Anyone know the exchange policy at Costco after 2 weeks?
Ive heard some wireless routers advertised as N can only really support one wireless N connection at a time.
Shouldn't have gotten a netgear router.

Why do you need "N" to work? Do you have internet speeds that fast? Are you getting dsl or cable running at 300mbps? I mean thats the only logic for wanting N on your phone, to have the internet be that fast. You do realize, the internet wont be any faster just because it travels over N vs G. If your internet is 10mbps, its going to be 10mbps over both G and N.
Recently my friend insisted that her new router be N, even though it was more expensive. She insisted she wants the fastest router. Then I said "You know...your home DSL is only 1.5mbps...having G or N won't matter, it will travel at 1.5mbps on G or N either way, you can't even max out G yet"
So my question to you is, why do you need N speeds coming to your phone. Are you under the impression this will make your internet faster? Is your internet speed 300mbps? If your internet is standard DSL or cable, you haven't even reached the top G speeds yet.
Is this making any sense?
I mean unless you do file sharing, thats a different story, but what kind of massive file sharing would you do between your phone and the router? LOL phones don't even hold that much information.
So even if they come out with Z technology thats 1 million times faster than current N, if your home internet is still standard DSL, doesn't matter if you run G/N/Z or any other alphabet letter.
take care
I asked a similar question a while back. This was the answer I got and it proved to be accurate.

The Vibrant's wifi is, as far as I know, 2.4 GHz only, but a typical dual band router setup does b/g only on 2.4 and n only at 5.8. If you have the option to do b/g/n on the 2.4 GHz band it should work.

why have a car that can do 60 mph when the car that does 30 mph will get you where you're going, eventually. /s
vibrant + allshare + NAS = happy tunes anywhere in my house. N just gets my tunes to me faster/farther.
your car comparison sucked.

Your car analogy made no sense. If you have a ford focus that tops out 85 mph, and a ferarri that tops out 260mph. However, you are limited to driving around at 30 miles per hour, doesn't matter which car you drive. Since you are limited to 30mph, the focus and ferarri are going to get you from point A to point B at the same time.
Same **** with G versus N on your vibrant. N can handle higher speeds, but if you are LIMITED BY YOUR DSL OR CABLE SPEED, THEN both will run at the same speed, until you max out G. The only way to max out G is to have dsl or internet that runs faster than G is capable of.
Again, only benefit of running N on your phone is for massive file sharing really fast, but your phone doesn't even hold that much info, so that makes no sense. Or the other benefit is getting signal at greater distances. Chances are your router that is running g/n is going to provide just as power a signal to your phone running G or N.
SO AGAIN YOU WON'T NOTICE ANY DIFFERENCE RUNNING N OR G ON YOUR PHONE IF YOUR MAIN CONCERN IS INTERNET SPEEDS.
UGGGGGHHHHHHHHHHHHH
Lets see. First off, if you do any media streaming via wireless in your house, you want the higher speeds. Second, I like to vpn from my laptop to my computer (so I don't have to leave the couch). The difference in the smoothness when on an n network vs. a g network is very notable. Third... And probably most important in a setup like this.. A single g device connected to an n router will slow ALL the wireless devices on the network down to n speed, regardless of what they are communicating with. It is this very reason I have two separate access points. One to handle n traffic and one to handle b/g traffic. So unless he wants to allows his whole network down, he should probably try to stick with n.

my car analogy doesnt make sense because you either a. have no sense of sarcasm or b. (i think its this one) u took my analogy and completely f'ed it up.
btw, i'm on an N network and my browser on the phone really flies. might shoot down to g only and see if theres a difference or if the increase is because i'm coming from g1/mt3g.
edit: web browsing...not a huge difference, deff noticeable though. allshare on g only was not that good, took too long to start a song. I like my N! lol
People who say that you need a 300mbps connection at home to take advantage of Wireless N are just being silly. Not only is there better coverage with an N connection, but you will also have better speeds if you have a decently fast line (doesn't have to be over 54mbps even)-
I'm a Verizon FiOS user with a 25mbps symmetrical (same up and down) connection. The problem with many G routers is that although they say 54mbps its unlikely you're going to necessarily reach that under real conditions. For example the stock Verizon FiOS router actually limits my speeds a bit, to around 20mbps downstream. If you're trying to upload at the same time its going to be a little slower even. That's about all I can get, especially when further away from the router. However, with a new wireless N router which I've just recently installed, I can max out full 25mbps downstream, and even have the same going through upstream at the same time. The range of the signal is better, and it even seems as if latency is slightly lower (or there's less 'jitter' in general). Wireless N allows for much smoother connectivity, and I would highly recommend it to anyone with a decently fast broadband connection.
Now having said all of that, you may not care about ~20mbps vs 25mbps (speed difference for downloads in my case) on a phone, and that makes sense as it probably can't even render pages fast enough to take advantage of that. But still, wireless N makes sense to have in general.
Its your router. Force it to use only N.
I find it slightly humorous that I feel compelled to justify WHY I want to connect via N. In future posts I will remember to justify all of my needs/desires first, I.e although I have a navigation system on my Yukon Denali, I dint have it in my Infiniti, so I want the gps to work.
Like others have said before, its faster when streaming videos, it has a much farther and stronger signal (i have a large house) etc. As to why I don't just force it to use n only, genius!.... I have a Wii, PS3, older xbox360, 2 desktops and 3 laptops depending on g. Currently only 3 devices on n. I like to share media. Is that enough of an explanation?
As I swype this response, I can see the wi-fi bar go from 1 bar to 3. It seems schizo.
On Speedtest, when I have n it pegs out at 10mbps, I can tell when its on g because it seems to tap out at 5mbps every time.
Again I just thought I would see if others have experienced similar issues.
Lock on dang it! You know you want to! It's the stronger signal!

By the way, THIS very well might be the issue in my current configuration!
Thanks to all the productive responses!
My Vibrant doesnt do that.
I have a Trendnet router
If you still have the recipt they still be able to return it or at least change it?
I have come full circle my brothas! My wireless router has n on both 2.4Ghz and 5Ghz bands. Thus, I should be getting the n on my 2.4Ghz-only phone. Ah, but here is issue again! The reason, among few, that I bought the wireless a/b/g/n router in the first place was for the distance magnification inherent in wireless n. This, you see, is how I came upon the issue in the first place. 1 bar alone do I get with the b/g signal, but 3 bars pop up now and again for a short time making me believe that the phone cannot hold on to the n signal!
Alas, my 30 days with this phone are coming soon. I think I shall exchange it on the morrow...
Does anyone know how to see if the Vibrant is using N or G? I gather from the post you can check it doing a speed test, but the internet connection would be the bottleneck. I took am looking for N Wifi so that I can stream wirelessly.

My understanding is, If you have g devices active on your n network, your entire wireless network will be limited to g speeds. This may well be your culprit

i agree with ConceptVBS. i had a similar problem with a netbook connecting at G speeds. i changed my network to N-only and now everything connects at full speed.
not sure the whole network would be slowed by one b/g device. i have a blackberry (for work) that connects at G, but my wife's desktop still connected at N speeds (270-300 Mbs).

[Q] Why is my phone's wifi slower than my computer's wifi?

They are both connected to the same network, but a speed test on my computer shows 10mbps while a test on my g2x shows 5.9mbps. Does anyone know why this is? Don't they use the same radio/wifi method? Why would one get more bandwidth than the other? Thanks in advance.
Is your computer actually connected by wifi, or is it using an ethernet cable?
Hi,
I have observed such behavior. These should be mainly because of cache differences between the devices. Also DMA access does matter when it comes to consuming data on a high speed interface. Wifi chips in phones are generally connected over SPI at 13Mhz which gives them roughly the speeds that you are getting.

So is there no way around this? I was just curious about it, and decided to google it. I dont know much about spi @ 13mhz.
On newer phones, the WiFi chip is generally connected to SDIO. Hence the speeds are much better. HTC sensation is one such device.

Wanted to revive this topic becasue I can not find any info on it.
Using my LG G2 at work, i am pulling only 12.81 mbps down and 14.43 up, while my computer is getting anywhere from 70-100mbps down and 70+ up.
Basically I am wondering if in general is there a difference between how a cell phones wifi connection speeds compared to a laptops or desktops? Should speeds be the same on both?
Is there anyway to bring it up?
I feel like this is the straw to tube analogy, your computer is 100x more powerful then your phone thus able to handle more bandwidth, if I'm wrong anyone please come through with an answer or correction

Shouldn't be a significant issue with the speeds the OP is talking about. If we were talking gigabit or greater I could easily see this being a factor.
Its simple, as much bw more power need to cast the signal. You probably could use a different kernel with more WiFi signal but I believe you will have to pay it with more battery consumption

The wi-fi receiver found on mobile phones is weaker (both speed and signal stuff) than the computers' ones. It's natural. I've experienced the same thing, too. Also, the modem-router's load or the webpage server you're currently visiting affects the speed, just to mention it.
Phone versus PC over WiFi issues
Phones are limited in cache size, processor speeds and usable memory, and those allocations are also being used by the phone's system and display, lowering the data rate over WiFi for the phone to use, regardless of actual speeds, WiFi can only channel available data at a rate commensurate with the available memory. There is no free lunch.
PCs have far greater memory allocation sizes, higher bus speeds and more capacity and bandwidth availability for ancillary devices, such as WiFi, which do not chew up computer resources, and can be allocated strictly for WiFi usage.
The small amount of resources used by WiFi in the PC is of little concern since the data is then routed to either storage, display, or to external resources, such as HDMI video, or a USB flash drive.
Phones suffer from low power consumption, which means power reserves are not as efficient on such devices, whereas PCs do not have this issue, so there is little problems supplying a steady amount of current to the WiFi RF board, which maintains a far more level signal output, and an adequate receiver signal gain so your range will not suffer as it usually does when access is performed with the phone.
Batteries are in a constant state of discharge, which means the phones are always consuming power, and usually rarely connected to a constant source of current like the PC is(redundant).

Very mediocre WiFi Performance?

Hey everyone,
I currently have a Note 4 and an iPhone 6 and I use a Netgear Nighthawk AC1900 router at home for WiFi.
When in my room, my Note 4 only reaches the speeds shown in the attached picture while my iPhone reaches the maximum speed possible on my connection, which is 90.
They are both on a 5Ghz network. The exact same of course. How can it be there is such a dramatic difference? I'm really thinking of returning it if there isn't a solution. I really love this phone though so I hope it won't be necessary.
EDIT: I'm reviving my own thread, since I found out something important. After restarting my Note, the speed test easily reaches the same maximum as my iPhone 6. After a while however, it drops back to 30-ish or lower.
It can't possibly be that this is a good thing, right?
do you connect your device at the same time ?
I don't know if it's still the problem with todays device, but my past experience (like 1 or 2 years ago), apple device (ipad and macbook in my friends and my experience) use wifi in some way so other device have worse wifi speed
But that just our experience in my college wifi network.
Yes they were both connected at the same time. Disconnecting my iPhone and MacBook didn't help either unfortunately.

Apple iPhone 6 comes with single band wireless AC adapter with duel-channel bonding 2Tx.
Galaxy Note 4 comes with dual band wireless AC adapter with tri-channel bonding 2Tx.
-->Single band wireless adapters have better peak performance because they are only connected to one antenna and all routers prioritize single PHY channel first. On the other hand, dual band wireless adapters have better consistent performance with higher max speeds because they are connected to two PHY channels, but have to sort out the distortions coming from two antennas. Some distortions can cancel out the signal that the device actually receives.
its the speedtest app which is messed up. i have a 25mbps connection and the desktop correctly shows 25mbps but the app shows 36mbps. try putting a 1 gigabyte file on an internal server and copy it to the iphone and note with dukto. you should get 144mbps or whatever your wifi speed is. 1 gigabyte at 144mbps should be around 1 minute to transfer.

So if I understand correctly, what you're saying is that in the long run, let's say when streaming or playing an online game, the Note 4 can more easily maintain a stable and fast connection, even though speedtest shows a fairly mediocre result due to it being like a 10 ten second test?

I have just contacted Samsung Netherlands and the guy I had on the phone insisted at first that it was my internet provider and the modem. After I told him I used a high-end router, not the WIFI modem my ISP provides, he kept on saying it was the router. Even after I thoroughly explained that all other devices worked fine in the same room, he kept on saying it was the router. All-in-all, completely useless, I would say. Are there any other things you can think off? Or any other XDA members to help out please!?
Try with 2.4 GHz.
5 GHz WiFi is extremely poor when travelling through walls.
Note 4 has a very small and insignificant antenna thus speeds drop tremendously when there's a wall in between WiFi router and phone.
I believe iPhone uses the whole metal strips on top and bottom as antenna
I have an Asus AC66U. On my Note 4, when connected with 5 GHz, and I am in line of sight with the router, I am able to receive a good speed ~ 200 Mbps. When in my own room, there's a wall, I can only get 12 mbps to 30 mbps.
However, my desktop uses an Asus PCE-AC66 wifi card. I am able to achieve max speeds of ~200 Mbps with speedtest. (It has 3 huge antennas).
Edit: My Desktop is in the same room where I fail to get any good 5 GHz speed on Note 4.
In the end, I just use 2.4 GHz...

Great, thanks. Can't wait to hear what they have to say.
until you do an actual test (i.e. transfer a file across from the network and time it) youre not going to get any useful responses.
like i said - the speedtest app is not useful as a test. its buggy and broken. its not your router. its the app youre using.

That was quick! I have changed the settings and I'll be home in an hour or two. I will do a test every hour from then to see if the WiFi speeds remain consistent.

Missing out with just bluetooth 4.x?

One of the few things holding me back is the Nubia having older BT4 tech compared to Oneplus 5 having BT5.
On top of that the Nubia Z17S upgrade due in Oct still only has BT4.
Is this is a big fail or is BT5 overhyped?
The phone is capable of bt5 (it's a feature of the SoC). It might be enabled in a future upgrade (it's what happened with the HTC U11). The advantages of 5 are double the potential speed and range. Range is only an issue with speakers in my opinion and speed doesn't come into play for me. Whenever I need speed I use a with connection (normally ftp, sometimes WiFi direct). I'd be more concerned with the lack of aptX.

WiFi slow performance, is this fixable ??

Hi Xda,
Got this new ASUS Zenfone 3 Zoom ZE553KL phone and wondering if I am able to change the wifi driver or system configuration because its locked down to only 802.11g often my phone gets only 54mpbs !! While my other phone 150mbps on my 2.4g router. Also the phone does not support 5ghz or dual band so it only can go up to 72mbps in the best case which it is not even capable of 5 out of the 10 times I use it.
This really sucks because I see a notable connectivity slow down compared to my older phones !! When downloading or watching a YouTube video.. Ridiculous that Asus did cut corners on the wifi connectivity back to a standard that was introduced between 2003 and 2009 !!!
The Snapdragon specifications website shows it should support 802.11ac 5g.
In my old Lenovo phone sits the same SoC, and it does have proper wifi connectivity.
Did ASUS cheat, is it really a snapdragon or a Mediatek processor? Mac address vendor of the wifi hardware shows Asus rebranding.
Can I even root this puppy?
Snapdragon specs say:
Wi-Fi Standards: 802.11ac Wave 2, 802.11a/b/g, 802.11n
Wi-Fi Spectral Bands: 2.4 GHz, 5 GHz
Peak speed: 433 Mbps
Channel Utilization: 20/40/80 MHz
MIMO Configuration: 1x1 (1-stream)
Peak QAM: 256 QAM
Wi-Fi Features: MU-MIMO, Integrated baseband
Even my 90 euro budget phone from back in 2014 went to up 150mbps..
I also have a bad feeling that there are a lot of cut corners on the wifi hotspot as well that I will have to use weekly for work.
If there's no proper way of fixing this. No more Asus phones for me. I already have a bad feeling that I need to VOID my warranty for it to be able to change anything like usually..
Other issues about the phone:
Bottom screen has two light halo effects in the screen (QC error !!!!)
And like always some problems (bugs) and removed features (latest firmware as of today)
1(bug). Set screen brightness to low, open camera app, close camera app, now the screen brightness will not always go completely down to what it was..
2. Show navigation bar feature missing. Change volume sound cannot be disabled.. Volume increasement half the steps of my Lenovo and previous phones. Blue screeen filter can't be modified, the default setting is useless because you can hardly see the difference.
Pros:
Regular software updates
Good camera
Amoled screen (but if you are unlucky you get a screen with halo in the bottom)
5000mah battery !
Other than that it seems to be a good phone for this amount of money.
You seems to be very confused. I've absolutely no problems with the wifi. It easily reaches 8-9MB/s on my 2.4GHz network and since I don't really care for the inferior 5GHz one that I do have but never use due to much weaker signal.
It's not the best phone in the world, but for the 140 bucks I paid for it, certainly it's a nice one.
I think you've set your expectations too high really.I see you've got a P2, I've had it for a while too and to be honest The Z3Z is better in so many ways, especially Camera, Speaker, Build, Price etc.
I'm afraid that you'll have to deal with the slow speed on wi-fi. I have a 100 mbps connection at home, and all phones i've tested get 95-105 speeds on speed tests, but the Zoom S is stuck at 54mbps. Unless you're willing to develop for this phone and see if there's something barring it from going faster software-wise, it is what it is.

You're right. It indeed is a good phone and the camera is better(speaker wise, I would prefer the Lenovo P2 but that's a personal opinion I guess), but I was disappointed about the WiFi, but yeah I'll just live with it. Seems they just didn't care about 5g for some reason. In my region 5G works a lot better then 2.4 even on longer range because of a lot of interference on the 2.4 spectrum. But yeah whatever, it works. The speed is indeed not terrible. Have done some more testing also with a WiFi hotspot I made and used in the hotel last time (worked flawlessly). I was in Germany and had a solid 4G connection, I guess the testing was in some way affected because of a poor cell reception or something (testing was done at home), or the DSL line at home had a slowdown at that time also not uncommon to happen..

I just deal with it, it is no big deal. Have been using the phone now for quite some time and it is fine. The only thing that sucks is that often in places where I go 2.4g spectrum is filled up with bull**** and it slows down or loses connection strength, this is why I would prefer 5g also, but alright. It is not going to happen..
Hey, I also had problems with slow WiFi. Almost to the unusable levels.
I've found out that switching Bluetooth OFF. Fixes the problem. Internet works back at full speed provided by ISP, and WiFi at routers' max.
I'm not sure if it's another firmware bug, or issue with MiBand/Bluetooth speakers.
I hope this trick will work for you
