SAR, Radiation, that kind of thing

You're probably not going to like this thread.
SAR levels... phone radiation, that kind of thing.
This isn't something I worry about that much but I've noticed some things since upgrading my phone over the years. Also, I've been in some areas with lots of radio waves and then in areas where there are very few radio waves and I have to say
If you think you don't believe in radio as pollution try standing in the middle of the rainforest where there is no power, no phone signal and you'll feel a sense of peace than cannot be compared to in an isolation tank in a city.
When you do this contrast a number of times I come back to the city and there's this sense of buzzing. Bear in mind this is from the ocean to a high rise apartment. I'm 100% sure I'm not imagining it, though I always accept the placebo effect where I could be imagining it, I've seen it so many times now and so clearly I'm adamant the human body's electrical nervous system can be effected by a lot/strong magnetic fields.
Basically I've noticed in years gone by that newer phones seem to feel like they're emitting more power than they did before when idle, but emitting less power when in use.
The reason I think this is because it used to take 20mins on the phone before getting a headache with a Phillips Savvy but that now takes now that takes 35-1hr on a Android gen of device.
However, if I use a modern phone and it's right in the centre of my chest I swear I can feel it. I wonder if there's been any double-blind tests on this. The thing is, I have WiFi on browsing like this and also 3G is at 2 bars but this feeling continues a little in 3G and a very tiny amount in airplane mode. This makes me think there's a magnet in there even during airplane mode. So, is the magnetometer always engaged like it seems to feel? Can we turn that off when not in use to save battery or is that proximity sensor always on?
As I say, I only don't like using the phone with it near my heart, I don't sense any problem anywhere else. Then again, more electrical signals come from the heart to the brain then the other way round so it could be a sensitive area.
Regards bluetooth. I checked out bluetooth headsets because they say the sweep spectrum should reduce area heating and so a SAR rating wouldn't even be possible. But that wasn't what it felt like. I still get headaches with bluetooth headsets, it's just greatly reduced. I figured it's pointless if it's not really working.
After a lot of research I found tube headphones and I use these just for longer calls.
The next thing I'm thinking is to optimise how the phone uses radio and sensors. This should be automated. I'd like to know how to turn off wifi when a connection drops rather than doing it by location in tasker for example. The same sort of thing should be done with GSM & 3G switching so what isn't needed is turned off. All of this meshes nicely with battery life - the 2 are synonymous. Why not enable call forwarding, carry a 2nd phone for GSM and only go out of offline mode for when you need to do something?
However, if my intuition is correct (this is one of the reasons I'm posting this thread), then SAR is just one of 3 radio signals coming out of the phone excluding electricity itself (EMF source).
So,
- so you get headaches during long phone call in the vicinity of the phone?
- do you find it easier to think clearly when on a wired connection compared to WiFi?
- have you thought about this much?
WiFi has been found to effect sperm mobility for definite but other than than it's all pretty unproven. WiFi seems to be lower power but somehow worse than GSM. Not sure about 3G.
However, phones are getting more and more powerful. 3G uses more battery than GSM and WiFi is an additional signal. Then we got 4G WiMax and all the rest on the way. Plus as I mentioned the seemingly minor development of the magnetometer. Is there any limit?
I never used to care that much until I experienced an electrically quiet place and then had to return to the drudgery of the city.
I still feel it's a subtle thing, but the effect for me can actually be very clear now, something that wasn't so for me in the days of GSM only, back then I didn't believe in all this at all.
Another thing I find is that typing on a computer without WiFi is somehow easier to think in a linear way without getting thoughts interrupted. I know, I know, this is a bit much now.
There is less energy coming off of your cell phone's radio transmitter than there is coming off of your computer screen that you interpret as visible light.. but the difference is that light bounces off mostly and if it doesn't it's burning your skin.
So, there's a load of info for you. Also some fixes too. Hopefully these things aren't a problem for you but also I hope to find people to discuss it with.
One thing I never understood was when training in the Air Corp we were taught to keep distance from UHF radios 25 years ago but then in the 90's and 00's phone radiation was not taken seriously at all and we still get people joking about it like it's taboo.
All this is very inconvenient for a tech addict. Obviously I've gone out on a limb with this thread. Be kind

Well, if you're "scared" of high SAR values, i would recommend you to get the Note. It's extremely low at 0.16 W/kg, and it looks like it's the lowest of all cell phones today. I personally don't care about SAR, but i can't complain if it scores well.
- Galaxy Note = 0.16 W/kg
- Samsung Galaxy S = 0.24 W/kg
- Samsung Galaxy S II = 0.33 W/kg
- Samsung Nexus S = 0.50 W/kg
- iPhone 3GS = 0.79 W/kg
- iPhone = 0.97 W/kg
- ZTE Blade - 1,35 W/kg
- iPhone 3G = 1.38 W/kg
- Sony Ericsson Xperia X10 Mini Pro = 1,61 W/kg (!)

Ah but one of the points I'm making is that the SAR is only for some of the function on the phone. I think it only covers 2G or 3G during a call. Afaik it's not covering WiFi, WiMax, sensors and also EMF which shielding is there to shield against you see. I guess what's needed is more info on SAR because while I know it's basic I wonder how basic it is. Holding a EMF meter next to a phone would be interesting too. In fact I have another android now so when I got this i9000 fixed I'll hold
Another point I am making is that according to the SAR values my i9000 should be better than my old Phillips Savvy but what I'm saying is that this is not what it feels like.
My guess for why this might be could be because a SAR rating only measures local tissue heating as if the amount of radiation is the only factor. What I'm saying is that it's not simply the peak power output that's important but also what is being transmitted.
I believe WiFi is lower power but it's closer to the frequency at which the human nervous system works.
Thanks for those SAR values, that's interesting. I don't think I'd be able to tell the difference between those values and to be honest I'm not that bothered. It's more of an interesting thing to talk about for me. The iphone looks interesting though, it would be nice to actually use one and see if it actually makes a difference in everyday use.
One thing to clarify is that while I'm totally sure that I can feel radiowaves I'm not too sure that it makes much of a difference to health, especially seeing as flying is a massive dose of radiation and so on.
More more thing to add, the signal effect drops off almost exponentially so if you hold it just 1cm from your ear you've made a reduction. I also prefer to keep it away from the centreline of the body, away from the spine.
That said, I wonder if SAR ratings are a cynical way to sell more phones, no?

Wales? East Anglia?
Arabian desert? Never noticed any difference.
Mobile operators in the UK have run their own tests where they've told people that a mast is active (and received assurances that those people can feel the EMF resulting in headaches/palpitations) when the masts have actually been off.
In the 70s and 80s it was electricity pylons being blamed for cancer, now people have grown up not thinking twice about them hypochondriacs have latched onto mobile masts, wifi (remember those "leave a chicken breast on your router and it'll cook" stories?), and now they're starting to blame wind farms.

Honestly, your perception is likely heavily weighted by the fact that in cities, etc you know all those devices are surrounding you. Most of what you are feeling is psychosomatic all things considered. Whatever the case, the only way to know will be long-term, properly-executed studies where perception biases can be overridden.

5GHz Wifi

I just noticed that my MX isn't seeing my 5GHz wifi.
Is it just my phone that needs to go back or has anyone else had this problem?
Sent from my XT1058 using XDA Premium 4 mobile app

I get my Netgear's 5GHz wifi to appear and can connect to it as well. I'm on the Dev Edition if that helps.
Is there a way for you to check if another device can see the 5GHz wifi?

Check what channel your 5ghz is on. I used wifi analyzer and under channels I noticed only certain ones were checked. I changed my router to one of those and it works great.

Your 5Ghz will have shorter range than 2.4. Are you fairly close to the router or access point?

Yeah, my GS3 had no problems seeing and connecting to my 5GHZ network. Seems like it might be a hardware thing.

My Moto X seems to do extremely well with 5ghz wifi. Way better that my former Samsung GS2. Much better range in particular, though still not as good as 2.4 ghz. However, this phone may have issues with some routers as I have problems with 2.4 ghz wifi and my netgear WNDR3700 as referenced here, http://forum.xda-developers.com/showthread.php?t=2433041&highlight=wifi+issues
I should also point out I have very little 5 ghz interference, but many neighboring 2.4 ghz access points. This is on small lots, not in an apartment so its still mostly ok.

Make sure the 5 GHz radio in enabled under Settings > WiFi > Advanced > Wifi frequency band

Yeah, I might have to get my phone changed out. My laptop is connected to 5ghz but my phone won't even see it.
**Edit**
So while looking at Wifi Analyzer, I realized that my phone doesn't support anything below channel 149 on the 5GHZ range. Mine is fancy wireless

There is a reason for that.
When your phone scans for a WiFi network, it scans through 11 wireless channels on 2.4Ghz (in the US). When your phone scans for 5Ghz it has more channels to scan through, 13-15 depending on your router.
That combined with already mentioned reasons such as better 2.4Ghz propagation in homes/offices makes it easier for the phone to connect. Whether 2.4Ghz or 5.8Ghz, every gain increase of 3dBm doubles transmit power. In one given spot with your router in another room, your 2.4Ghz signal is typically going to be stronger. It is going to choose the 2.4Ghz because the phone scanned and saw it, and the signal was strong.

yup. i ended up forgetting my 2.4 bands in favor of the 5. now i'm upset that nothing else in my house uses the 5.

There is also a chance that depending on the cell band and frequency your phone is using it may disable certain wifi channels as they may interfere with each other. I know depending on certain cell/wifi/bt combos various power levels in the phone are reduced, I wouldn't doubt there are other rules in play as well.

In the US, 2100Mhz and 2500Mhz are the closest freqs used near a WiFi router. Channel 11 is 2462Mhz, with 3 more channels left before hitting 2.5Ghz. No carrier to my knowledge uses 5Ghz. DFS starts at 5260 to 5700.
However, BT uses 2.4Ghz, though the radio in your router likely has more output power and will force the BT to change the channel it is on.

There is way more in play then that. When a radio transmits on 850 Mhz is also transmits a lower power carrier at 1900 Mhz (known as harmonics) They are greatly reduced in power level but if they are right beside the receiver(as the case would be in a cell phone) it can cause problems. With all the possible bands a phone can transmit and receive on there will always be combinations of harmonics that will reduce the performance of other receivers in the phone. It is also possible to have further issues from mixing products but I won't go into that here.

True. I didn't really think to mention harmonics, as most people do not care nor do they understand. There are many things at play, as you said, and I will be the first to say that I do not know all of them, but you raise a good point. I am still not sure if anything running on 1900Mhz would cause issues in the 2.4Ghz band, but I have seen much stranger things happen.

OnePlus 3 Pokemon Go no good

I've been playing with Pokemon Go for a week now and find the OnePlus 3 not very good with Pokemon Go.
Running latest Oxygen OS 3.2.1
The game itself is already buggy and laggy depending on your connection but on the OnePlus 3 it seems more unstable than other phones I have on Tmobile.
I can't blame Tmobile since I've compared Pokemon Go running on other phones using the same service or sim card the OnePlus 3 is the least stable.
My wife uses S6 and it too has issues but not as bad as OnePlus 3. Doesn't freeze or lockup as much.
One the Samsung Note 4 running Kitkat, it seems to work the best. Freezes less often more Pokemon spawns.
I also have a LG G3 running Lollipop also on par with the Note 4 gets less freezes also.
My guess is the OnePlus 3 GPS & radio reception is inferior to plastic Android phones.
One strange thing is that I had the Note 4 tethered to the OnePlus 3 and it seemed to get more Pokemon spawns. Which sort of validates my theory that the Note 4 GPS is superior to the OnePlus 3.
What do you guys think?

I had the exact same issues! Pokemon Go on my Nexus 5 is smooth and on my OP3 it was so laggy and stuttery. I have since sent my OP3 back. The reception was the worst of any phone I've owned.

Works great on mine and finds a GPS lock about 10x faster than my OPO.

@vision33r
This has absolutely nothing to do with the phone, (if it's not a faulty one)
Stop giving Oneplus such a hard time and go ahead and delete this thred. Menaingless in it's highest grade.

I have pokemon Go installed too and no problem with it so far.
You maybe you guys have some apps that conflicts with the game, here what should you do, try the game with a fresh install of OxygenOs and/or try it with CM13

I'm posting this to see if people share the same real-world experience. I think it deserves some attention because I've had OnePlus 2 and the signal quality is pretty good. The OP3 I believe may need some tweaking, because its got a Snapdragon 820 much superior than older devices but yet I am able to get better performance on Pokemon Go with older devices. It maybe radio signals as Pokemon Go is very data intensive.

My OnePlus 3 works just fine. The problem is that its hot as heck.

Lol it works pretty good on my OP3. Pretty sure it's just you.

I've been playing since it was released on my OP3. Also have S7 and S4 phones same network. It's laggy but equally to my Samsung's. Seems the same for me on any phone I try. I'm very happy with PoGo on my OP3. It's niantic that sucks. Also I haven't had any reception issues... Hopefully that's just rare faulty devices.

Works great on my phone. I'm using rooted 3.2.1 stock.
Here's a secret: works even better with Xposed "add on".

no problems at all with my op3. it freezes as often as it does on other devices.

fine on my OP3 aswell, freezes are server/app related

It clearly is not just him.

I live in a suburban area and go to work in a very urban area (downtown San Jose, Ca) and I haven't had an issue with GPS or 4g/3g signal (in parking garages or the office buildings). Pokemon Go is almost always smooth for me, except for when there is server instability. Compared to my Oneplus One, my spouse's iPhone 6 plus, and my brother's Galaxy S5, I tend to get more stable data signal.

It's good to hear that some people don't have problems. However, a very large number of people do, which is not acceptable! Even for a cheap phone.

It's the other way around, most people don't have problems.
I just can tell you its running smooth, i didn't compare framerates with other devices nor did i check the fps my device delivers.
When the App bugs its the same bug as it occures on different devices, therefor not OP3 related.

I did some further testing, I do think the OP3 has a smaller & weaker signal range. I'm getting about -113dbm to -103dbm compared to my Note 4, getting about -93dbm to -100dbm around my house where there are two Poke centers that I frequent.
Last night both my friend and my wife gotten Ghastly at the center and my OP3 did not get it. I quickly tethered my iPad Pro LTE to the OP3 and sure enough that Ghastly showed up.
Keep in mind my OP3 already has Google Maps offline enabled for the area and the iPad didn't My wife's phone is S6 Edge and friend has Nexus 5X.
So something is up with the GPS, the data seemed to be ok as the iPad tethered to the OP3 gotten much better results.

I figured at some point they will disable running on rooted or jailbroken devices. But I really don't want to cheat because to me the fun part is catching them. It wouldn't be fun if I just cheat and take away the fun part of finding them.

99% of people with this phone most likely have no issues at all with PoGo...

Now, moving on, after doing some tests, the OnePlus 3 is clearly inferior to it's testing partner the LG G Flex 2 when it comes to general reception. Using the speedtest.net app, the OP3 consistently has weaker speeds than the Flex 2 on T-Mobile's 4G LTE. The upload speeds were drastically worse than the download speeds for some reason.
Second the OP3 also appears to significantly pick up less satellites using the GPS Test app.
My findings line up well with the OP's observations and the concerns many already have regarding the reliability of these features.
Below is a side by side sample of the general GPS performance differences between the OP3 and the LG G Flex 2. The screenshot with the VoLTE icon obviously identifies the OP3.

[FIxed]Note 9 vs p20 pro Download speed

I was feeling there was an issue with my Note 9 compared to my Note 8 and P20p Thus i decided to do a speedtest. the phones were at the same place and nothing was using the bandwidth. Surprise. look at the video, and you will see. (N8 and p20 came with the same results).
I would like to ask some of you who already have it to test it against other phones to see if i'm the only one with this issue. I have the latest firmware on it and didn't test it before the update...but this is really not normal. I also feel it's just "slower" in general than the p20p...
check this link for the video

Upload video on Youtube plz

Yeah, as a network engineer I'm not going to touch random files on a Dropbox. At least link a speedtest.net result or the image.
I have my note 9 coming on Friday so I can put some effort into getting the optimal wireless connection (there's so many variables involved, I'm a wireless network engineer working for a wisp so all in my realm of knowledge) and give it a test.
I'd be very surprised if its a downgrade compared to Huawei, Samsung spend a lot of time on their LTE radios, now running on CAT 18, with MIMO, for a theoretical bandwidth of 1.2 gbit/s. Will know for sure Friday!

Can't find info on the chipset in the S9+, but I can find that they have MU-MIMO and 1024QAM, so it definitely should be quicker if you have a router supporting the above.

I have my note 9 coming on Friday so I can put some effort into getting the optimal wireless connection (there's so many variables involved, I'm a wireless network engineer working for a wisp so all in my realm of knowledge) and give it a test.
I'd be very surprised if its a downgrade compared to Huawei, Samsung spend a lot of time on their LTE radios, now running on CAT 18, with MIMO, for a theoretical bandwidth of 1.2 gbit/s. Will know for sure Friday!

Can't find info on the chipset in the S9+, but I can find that they have MU-MIMO and 1024QAM, so it definitely should be quicker if you have a router supporting the above.

Here you go guys. will update the original post also

PS : for information i'm on Ubiquiti hardware here.

Strangely i was able to when i cleared cache....

Aha, well, I'm UBWA certified actually
We're bound to see some minor oddities like such before launch, nice to know its not the phone!

not that shocking to be honest shocking would be getting like 2mg dl not still nearly 50 lol

Shall do!
I'll be doing it for my own amusement so definitely happy to share!

Since the test was on WiFi, and not LTE the work Samsung has done on the modem is irelivant.
My question is, are they really on the same network? The results make me think that your Note may be hitting the 2ghz network not the 5ghz network.

Read the thead mate, it was a cache issue. I was only pointing out Samsungs dedication to connectivity, and I did follow up with somewhat comparable specs for the radio.
It could be a number of things, potentially more sensitive radio in the note 9 that struggles to handle interference, etc, it'd be pretty obvious to be on the wrong network.

Perhaps Mate, you need to clarify... first you wrote "shocking!" in the header of the thread, then in one post you said "Strangely i was able to when i cleared cache...." which didn't mean anything to me, and certainly not that you discovered the problem.
And no... being on a 2ghz network vs 5ghz network can be an invisible decision made by the hardware, and many networks are using the same network name. So it wouldn't necessarily be obvious.
For example, in my house, the network ID is "MyHouse" for both the 5ghz and the 2 ghz networks... the Chromecast is on the 2ghz network, and my phone is hitting the 5 ghz network. They see each other and is seamless.

Dude, I don't know one router that has the same SSID by default for both networks. Someone changing the network should notice the difference then.
BTW, I'm not OP, just someone helping.

Definitely not an issue!
http://www.speedtest.net/my-result/a/4187326458

Though i would add my results here also, Verizon snapdragon model. Definitely seems like something is going on with your test. http://www.speedtest.net/my-result/a/4188275993

so you guys testing your wifi speed using your isp network is telling us what exactly?
at best you should test locally but even there. if your network equipment is not on pare then again your testing with too many faulty variables and it won't show phones true potential.
ignorant people would state that a phones wifi has issues because upload speeds sucks compared to DL or just both seem slow.
but in fact what sucks is ISP internet package and not the phone. obviously other parameters like specific servers the test is being done on can co tribute to faulty 'online' test results.
so we have a few factors which make tests like these irrelevant:
-****ty internet package subscription
-****ty test server
-****ty home network
for cell data tests, well we need good weather and be near a cell tower.
but again this proves less concerning phone's capabilites as throughput but more towards signal quality.
and the average will be provider's coverage. how many towers they utilise and your signal strength in general in most common locations you visit.
*btw OP dude, do everyone a favor and correct your thread title...

i was tested on 4 devices, Note 8, XZ2, Iphone X and Note 9, so seem XZ2 always faster and winner

Sorry dude, but there's so many more factors to be able to throw any of this out. I really hope no one is taking this that seriously.
For one, I have no idea about the noise floor (background EMF noise level) on whichever frequency people have decided to run your AP. (Be it 2.4 or 5ghz, and then which channel, 2.4 ghz only really has three channels, 1,6,11, with the other channels just being overlaps. 5ghz has a lot more but usually everything is on 5180 (channel 36) due to DFS above 5250mhz in mos6 countries. Chances are all of you are suffering from interference.
Then we could talk about MIMO. Each MIMO chain nets you +3db so routers supporting MU-MIMO could see big signal increases just from both devices having multiple MIMO streams going on.
S9+ (and probably the note 9) supports QAM1024, essentially fitting more data over a link at once to the risk of needing a higher signal to noise ratio (this is where noise floors and interference comes heavily into it)
Every situation is unique, I think we should try and explore but please share your enviroment, I.e your router, where you are (apartment, house, city, rural etc) and then we can only start making sense of things.

but you have to agree that it is folly to report wifi speedtests using home internet and its limitations by the ISP as being a way to gauge a phone's capabilites.

No, I'm not sure I agree.
If you cable into your router and do a speed test, and use that as your comparison point, I don't see the problem with using a home connection to test.
I don't know what limitations you're talking about, in my experience for speed testing you're routed into the DC where your ISP has its presence then either a speed test server within your ISPs DC network or one right next to it in the same DC.

Now if you're using the router supplied by your ISP, whole different story.

Slow WIFI speed

I have a 150Mbps internet connection which hits up to 170Mbps . I don't have separate band for WIFI. I ran speed test on my pc connected to the WIFI and it shows 161Mbps and when checking the same on my Galaxy Note 9, it doesn't go more than 90Mbps. Any help is appreciated. Thanks.
Note: I have turned off Bluetooth, Location and sim services. Done resetting and clearing cache. Tried the same with no other apps installed.

Just tested without disabling anything (bt on, many apps in background etc).
So Exynos model wifi is much faster than 100Mbps.
Something's really wrong with your phone or wifi network.

On my router at home, sometimes when I connect, I have to reconnect straight away to get the best speeds. I think it might be something to do with 2.4 vs 5ghz bands.

Your rooter is probably at fault. You need an AC rooter with more than 300 MB (as its 150 dl+150ul) set on 5Ghz with 80Mhz. Look at my stats on a Gigabit connection. I did the test while streaming a 4k hdr tv show on netflix

Thanks for your reply. I have tested my router with multiple devices and the speed test always shows above 150Mbps. The issue is with my mobile or the config that my router does when connecting this device. Can you please provide any advice on this?

I'm having slow Wi-Fi performance as well.
I discovered it when I was doing concurrent benchmark app downloads with my LG v30+.
The Note 9 was at least 1/2 as slow (or slower).
Same network & same time so it's not likely a router thing in my case.
This was at work so It's 2.4Ghz.
I'll try testing at home on 5Ghz to see if the issue is the same.

With this morning's tests the phone seems to be performing better.
I downloaded two different apps, and at first it started out slower but both times it caught up and ended up downloading faster than the control phone.
I'll keep checking and report back if the issue returns.

It's baaaaaaaak!
I thought it was better.
But started noticing I had messages sitting unsent, and just general download slowness.
Did another side-by-side comparison with the LG V30+.
Two of these tests were done simultaneously, two sequentially.
All are looking pretty bad for the Note.
Did a "reset settings" and a "reset network settings", didn't improve anything.
Just did a restart and it fared no better.
I may have to resort to a factory reset, don't want to as phone is finally all set up.

I'm hoping it's fixable.
I gave Samsung a second chance (I had the Note 7).
I'm really liking the phone, but I really like my LG V20 and V30 and the V40 is about to drop.
I'm within the return window at Sprint, gonna have to decide soon.

Update,
My work's router seems to be the issue after all.
I'm not able to reset it during the business day, but I did plug in a second router into it and the speed improved greatly.
It seems to now be on par with my other phone now.
I will keep testing.
Second update:The 5Ghz is smoking fast, 66Mbps up/down. This is on the secondary router.
I'm not sure why our router hates my phone but it does.
Connect to it; little to no Wi-Fi throughput.
Connect to the router plugged into it; normal Wi-Fi throughput.
Since I had two comparable devices connected to the same network, It never would have occurred to me it could be the router.
Another good step to do that I forgot about, after resetting settings power off and boot into bootloader and clear the cache.

Verizon Note 9
My Note 9 is slower than other devices on my WiFi network. I have Galaxy S8 Plus and Fios 75/75 service , when I run speed test my S8 shows about 80/80 but Note 9 never goes more than 65/55 . The same results with my second Note 9 , so it definitely problem with their phones. Shame on you Samsung!

my wifi is broke, I'm not getting 1Gbps:
