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.

Got my hands on a G906L Korean S5 with 805 and QHD display

I was gonna wait for the iPhone 6 because I thought even if I don't get one It is still a good idea to wait and see what they have to offer because (fanboys, please be realistic) they usually set the bar for the next one or two years to come.
Now the iPhone 6 is out, I'm a bit disappointed, but not toomuch. Not because of the design or anything, the design is great in your hands, the screen is superb (for LCDs), It's just that the performance is really underwhelming. Maybe it's because how the A7 Cyclone cores kicked android ass so hard(single core performance) they are starting to get lazy. A mere 25% improvement at most? Thats probably the lowest improvement in CPU performance of all iPhone generations. The GPU's 80% improvement is decent but not very impressive for Apple.
My old phone was the HTC One X, it's so old and rare I haven't seen anyone with it for months. Even though I managed to get Kitkat running on it the battery life is still horrible and I'm tired playing around with the crazy wakelock bugs and **** so I had to change.
So anyway I didn't want the S5 because it's already 65 years old so I got the newest flagship there is, the Korean Galaxy S5 LTE-A with SnapDragon 805 and a QHD display, in the same form factor as the classic S5, which I kind of like because I don't like flashy exteriors.

To be honest I was getting tired with all the tweaking you had to (maybe just because you could?) do in Android and was prepared to get an iOS device that just works out of the box. But I guess duty called and I could not turn away from the power that do come with the responsibilities! So once more I dive back into the tweaking game, well maybe not so much because there is only one not so custom ROM here on XDA for this device.
This device obviously has the same plastic build as the classic S5, except all the fake metal parts are now slightly golden instead of chrome. I really don't mind the plastic and I never did, because this isn't a heavy laptop where plastic construction makes for cheap squeeks. The phone is totally solid, so I don't really see the point.
The screen is pretty much the same as the classic S5, but in 2560x1440 resolution. Which is just stupid large because it's a way smaller device than my 2560X1600 MBP 13", which is a way smaller device than my 1920X1200 desktop monitor, which is a way smaller device than the average "HD" TV, yet it has equal or higher resolution. Better still, it doesn't consume any more power than the FHD version.
The performance, I actually don't really mind, as long as it doesn't lag, and it doesn't, so I'm happy. From what I know, the improved GPU makes up for the extra pixels and has a bit extra, so I'm really happy. But I'm somewhat surprised that even at the insane 577DPI, you can still see aliasing in games, I don't really know why........
I understand that this isn't the most impressive handset for battery life but my god what an improvement from that piece of **** I was using. Not only does the battery last forever, it also charges so fast! Super impressed.

Ditto. Feel lucky for not plunging into the Note 4 craze. Got my G906K in Hong Kong for a mere USD528 instead of 810 for Note 4.

Where do we stand with the warranty on these phones? Will Samsung UK repair the phone if it goes wrong?

There is a catch. Mine is an imported model from Korea which is not covered by 'normal' support maintenance by local Samsung office. I'd have to bring it back to the shop which imported it should something go wrong. Guess the same applies in UK.

Yes warranty is probably the biggest problem with this phone, and in case you smash the screen there would be no way to fix it. That's why I got myself an aluminum rim case and gorilla glass screen protector.

iirc it's like this, basically samsung has worldwide warranty, except they have the right (meaning they don't have to but can) to deny you service if you're in a different country then where you bought the product. I've tried getting service for my canadian device in sweden and it worked 2 out of 3 times (without receipt). it depends on how much you care for your consumer rights and what kind of person is on the other side of the counter. if it's a lazy/informed service agent he'll tell you he doesn't service imported devices. if it's a good person actually trying to help you'll get service. etc..
the other thing is a lot of the time they're not educated on servicing foreign models, and they either ask you to pay for shipping to country of origin or it takes a long time for them to learn about your device and fix it.

"you can still see aliasing in games, I don't really know why........"
Because the game isn't running at screen resolution.

I was referring to Real Racing 3, which is already choppy during the start with 50 other trash drivers blocking your way. So seems like you can't really play a game like that in native resolutions because it would just lag too much?

Hi, thanks for the response, I think that I can't choose the network mode because it's like locked with the settings of the factory carrier (LG U+, something like that)... Is not possible? If I flash a stock rom or custom rom without any carrier, I think it will solve the issue... And talking about the bands I'm leaving here a screenshot of the information that the seller of Amazon put for the product (I bought the phone on Amazon)... And my phone show G(gsm) sometimes and almost all time show 3G(H or H+)... So I think it have the corrects bands doesn't it? I'll wait for your response and then proceed to enable more bands... Or if there is a test that I can run to know which bands I have, tell me to do it assap! Thanks again for the help!

No option for change the network mode... :
Ahh, and do you know what rom can I flash to my phone?

WiFi strength, range, and throughput

Rate this thread to express how you think the HTC 10's Wifi performs. A higher rating indicates that it has excellent range, throughput, and signal strength. Like when you're taking a dump in the bedroom upstairs, do your videos have to buffer or do they come through without interruption?
Then, drop a comment if you have anything to add!

I am getting drop-outs on my WiFi connection even when feet from the router. The strength is OK but it drops connections, and when making WiFi-based calls the phone complains that WiFi signal strength is low (even when max bars! Clearly this needs and fix from HTC as others are reporting this too.

when I use the normal wifi from my router I seem to have issues but I'm on very old firmware still from Verizon 1.19. I hear the update helps out with wifi issues. When I connect my to my router using the 5G connection it works flawlessly.

I find the wifi strength is not top notch. Very easily it drops its speed. Using ICE Rom.

I vote excellent. I walked away from our apartment the other day and my 10 clinged on to it's dear life and maintained 1/5 bars where my M7 and missus's G3 just went: nope.
I'll have the "ultimate test" for my 10 next Wednesday. Going to school and in our "lab" we have a WiFi router. This lab is basically a bunker, a bomb shelter.
My M7 could pick up the WiFi from there (with the door closed) fine in a couple of locations around and near the bunker. It's going to be interesting to see how well my 10 can pick it up.

Wi-Fi singal to me is a great, but the speed and connection seems quite off. At times I can use my laptop while my HTC 10 is connected to the same Wi-Fi connection and my laptop speed will be great, but the HTC 10 seems quite sluggish. Additionally, sometimes I will get an error notification with Wi-Fi calling, and sometimes I'll get dropped calls when I have great Wi-Fi signal.

WiFi signal is absolutely horrible for me. Most of the time I only get 1-2 Bars except im really close to the Router.
My Tablet and other phone always get way better Signal strength.

Wifi on HTC 10 is the most horrible implementation I have seen on any device. If you think your wifi is great, go contribute your debug logs to this thread: http://forum.xda-developers.com/htc-10/help/wifi-constant-suspend-resume-leading-to-t3392562
Vote on that thread only after doing the diagnostics, not by "oh, my wifi is great because I can browse on my phone".

I had issues before update 1.80.401.1: connections never seemed stable
Now on the update I've nothing to complain about, throughput is good, ping is stable and the wifi never seems to drop again.
Roaming between access points is also great, no drops there as well.
The range is fine as well. From the house to the garage (about 30m away) I still get a good enough signal to use internet, watch youtube etc.
That's through 2 brick walls and a garden with trees

Wifi range on this phone (HTC 10) is atrocious. The phone is basically useless to me. At home, it refused to connect to my 5ghz band and would only connect to the 2.4ghz band, unless I was within 5ft of the router.
We are currently in Costa Rica on our honeymoon, and while my HTC 10 remains in the hotel room safe 99% of the time while we surf, explore etc., the few times I've needed it it absolutely refused to connect to any of the 3 wifi networks here. Meanwhile, my wife's Galaxy S4 connects to any of them with no issues and gets 20mbps download speeds. My Macbook Pro has no issues and two other people we've talked to have had no issues with their iPhone and LG G4.
I wanted to love this phone but it's given me nothing but issues when it comes to network connectivity. I made the last second decision to leave my Nexus 6P and bring the HTC 10 in an effort to have a smaller phone with me during this trip, but I completely regret it. As soon as we get home the sim card will be pulled and the phone will be shoved into a drawer until another worthy phone comes along to use my next JUMP! Ondemand upgrade on.
It's too bad HTC is making the next Nexus phone. Because I sure as hell won't be buying it after this B.S. experience.
Also, for reference, when I got the phone from T-Mobile I unlocked it and flashed the U.S. unlocked RUU firmware/ROM for faster updates. I had these issues on the 1.53.617.5 RUU and they persist after the latest 1.80.617.1 update.

@sn0warmy do you have the uh oh warranty with 1 day replacement? Because I wonder if this is a hardware issue as some people report good WiFi.

I'm not entirely sure. I do pay for the accidental coverage through T-Mobile and I'm sure I could use that to get a replacement through them (they've always been great in giving me replacements when requested). But I've seen so many people with the same issues, who report the replacement doesn't solve the problem., that I almost just don't even want to bother.

I had the same problem and a replacement for a new phone did the trick....

In my experience, it is mediocre at best.

Rate this thread to express how you think the HTC 10's Wifi performs. A higher rating indicates that it has excellent range, throughput, and signal strength. Like when you're taking a dump in the bedroom upstairs, do your videos have to buffer or do they come through without interruption?
Then, drop a comment if you have anything to add!

My HTC 10's wifi reception and speed is noticeably worst than my LG G3, and MUCH-MUCH worst than my 6 years old Dell Vostro 3350 laptop. At first I thought that my specific unit is defected, and went back to the store to replace it. The store's manager claimed that "it is what it is", and allowed me to examine and compare it thoroughly to his Smsung S7. They performed similarly. Some consolation...

WiFi signal is absolutely horrible for me. Most of the time I only get 1-2 Bars except im really close to the Router.
My Tablet and other phone always get way better Signal strength.

Totally agree man, my old M8 was WAY much better compare to my HTC 10 unfortunately.
I use to get almost full signal in my house at the second floor with the M8, with the HTC 10 cannot even browse.
I have to say this is the only thing that I don't like of this phone, hope a new firmware will do something.

Yeah, I'm on the latest OTA, 1.80 and Wi-Fi is better, but not as good as my old LG g3. Just enabled 2.4Ghz only, and it feels better

Agreed, reception is terrible, I bought the unlocked t mobile version through htc, am on the latest update 1.80.617. I am currently sitting in a hotel room with crappy wifi service, but next door there is a walmart with a strong signal and I am connected through that on my laptop with 4 bars, but I can't get the 10 to connect at all.

Oh look, there is still one bar left.... no reason to switch then....
GTFO WiFi... GTFO

This is well know android issue that has nothing to do with htc.. Android has wifi roaming issues, same happens with samsung ore oneplus...

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. Can you suggest me a way to fix this issue? I can provide you screenshots of my router config and mobile.

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.

Fastest wifi I've had on a phone yet

Thanks for your reply mate. Waiting for your test result.

I think i would help if you specifi if its a 6GB Ram or 8GB Ram version.

It is 6GB, exynos 9810, the base variant in India.

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:
