4g signal strength health issues - Xiaomi Mi MIX Questions & Answers

Hey guys yesterday i upgrade to 4g sim card and got 4g signal for the first time in my life lol. However after using for a few minutes using phone i start to feel nausea tired dizzy. Dont kniw why. I guess the reason is the signal from the phone is too strong. My tel service provider use 1800mhz band. Does anyone experience similar issues or is it just my imagination lol

Probably just your imagination! Lol. The SAR values of these phones are within the acceptable levels and aren't harmful in majority of cases. People who set these guidelines and standards go through a lot of research so that we end consumers don't have to. So it is safe to say that it is just your imagination that 4G is the cause. Your mind is just trying to associate two different events; getting 4G for the first time and a random episode of fatigue or a headache. Considering you also mention that 4G signal is quite strong in your area, your phone only requires very less power to lock to the network, meaning very low or negligible radiation.
But it would be best to visit a doctor who may be able to help you with the symptoms.

Is the Nexus One 3g issue a dealbreaker?

Title says it. Contemplating purchasing this phone because I want a sick Android device but its plagued with bad 3g reception stories. Is it that big of a deal? Does anyone regret buying the device over it? Is it a design flaw as i have read or software?

It is neither. It is the wireless networks you guys have here in the US that sucks... (At least in El Paso, TX)
I'm tired of people blaming the wireless network, because that's just plain wrong in most cases.
I am a big N1 fan but I will be the first to admit that there's a 3G problem. But here is what I've observed:
- The problem is less evident on the AT&T model, as 3G runs on the same frequencies as 2G, and in general AT&T uses 850/1900, which are lower frequencies (better penetration) than T-Mobile.
- If you're in a very strong 3G area (like on the streets of NYC), you aren't likely to have any problems no matter how you hold the device.
- If you're in somewhat of a sketchy 3G area, and use the T-Mobile version of the phone, it's very possible you're going to drop to edge, if you cover the bottom portion of the phone with your hand. If you have the AT&T version in a sketchy area (low signal overall), it's possible you'll kill your signal entirely if you hold the phone a certain way...but I would say this is very rare.
There's probably a combination of a software and hardware issue causing the 3G issue. With future updates to the radio firmware, I'm sure there will be some improvements, but I don't know if it's going to be as good as some of the other phones available (especially in the case of T-Mobile, where the G1 tends to be fair a lot better 3G wise).
Having said all this - do I regret purchasing an N1? Definitely not - everything else about the phone makes up for the 3G issues, and I still have hope for future improvements.
Reception isn't "deal breaker" bad, and you'll notice there are much less complaints from AT&T users about it. If you are normally in areas with good coverage everything will will be great, but fringe areas might be frustrating. Weak signals are the phones kryptonite.
My question to anyone on the fence is usually, "name a better GSM phone" and then when they say "iPhone" I call them a fanboi. There's nothing worse than being an Apple fanboi.
its not a deal breaker at all. I still hold by my theory that the signal bars are just calibrated less conservatively than other phones, cause I've made and held calls for 15 min with zero bars of 3g showing. even my nokias had trouble doing that.

Just cause they say the iPhone, doesn't make them an Apple fanboy.. people can have legitimate reason why they like the iPhone more than the Nexus...
There could be something to the theory that the phone just reports reception more conservatively. But then again I can easily drop a call in a low signal area by moving my hand around. This is the first phone I've had that does that.

see i have always had the same problem with my other phones in low signal areas, they would ALWAYS drop the call if i moved my hand over it. but they all had antenna in the bottom, like the nexus. i think if your previous phone had the antenna in the top, then you never would have experienced this before.
my nokia n95 was the last phone i had with a top antenna, it was internal at the top near the camera, and that thing was superb with RF.
but then i got the e71 and the bottom antenna dropped calls when i covered it. no service, all the time. i trained myself to hold at the top ever since.
so the nexus doesnt seem abnormal to me. i just thought it was common knowledge though...

I also hope you were joking about the fanboi thing, as the nearest I've come to owning and iPhone was using family members ones for a few hours. My previous phone was a G1, and your misconceptions of me (if your words were not taken out if context) for stating something that is quite true is quite sad.
As stated before, people can have legitimate reasons as to why they favor the iPhone more than the Nexus. If I was sucked in to the iPhone when it was released, I would probably also be an iSheep - luckily I was only 12 at the iPhone's release. Phone technology wasn't really all that interesting yet.. I didn't care about touch screens etc. Now though, I still don't care about the phone much - but it was definitely brought unneeded hate in the internet towards those who adore it.
I love my Nexus One. No 3G issues on ATT, this actually has much better reception than my HTC Tilt2 with the best custom radio rom for my area. Flashing the radio of your Nexus will help a ton if you experience any of these issues so if you plan on flashing your phone don't worry about it. I love my Nexus and I spend much less time screwing with how the phone works and a lot more time using it.
about nexous one
I have never had any 3g problems ever and i bought this phone right when it came out
i love it get it you will to
This is really simple.
1. Buy the phone. If you have bad reception,
2. Flash to the newest radio. If you still have bad reception,
3. Return the phone.
You most likely won't get to step 3.
The phone legitimately does not get great reception.
I lined up, side by side, my BB Bold 9000, my Motorola Milestone, and me Nexus One, all just sitting on the desk, all with Orange (France) 3G SIMs.
The Bold and the Milestone get about the same signal. The Nexus gets consistently -4 to -10 dBm worse signal in any given placement. Wrapping your hand loosely around the phone will cut the signal by from -6 to -10 dBm on the Nexus, and by around -2 to -6 on the other two.
HOWEVER, the statistics don't really matter - I still get good enough signal at my desk on all three of them to download applications, use GTalk/SMS/telephone/browser all day, etc. Yes, a speed test shows generally better speeds on the Milestone, but it is more than good enough on both Android phones.
AND the Nexus is much faster in day-to-day operation. It scrolls faster, loads faster, runs faster, etc. It is almost sure to get updates from Google faster, and the dev community really does rock.
If I was in the US, I would have to consider some of the other phones out there, simply because the other networks are better than GSM networks, but here in France, the Nexus is fine and dandy.
If I were you, I would consider the network as well as the product, because it makes such a huge difference in the US. But once past that point, if you decide Nexus: buy it, test it, if you don't like it, sell it or return it. Easy.
I carried around my iPhone 3G with me the last few days and any time I had bad or no reception with my N1 I would swap the sim card and try the iPhone and without fail the iPhone would alway have more than enough signal strength.
The phone's reception is simply not as good as other phones, but it not enough for me to want to return it. I just hope that HTC learns from this like they did with the recent change to the atmel touchscreen instead of the clearpad component. I'm sure they will.
I've never had a problem with dropping 3G signal exactly, just the occasional instance where it'll get stuck on "uploading." Not sure if that's a T-Mobile issue or a phone issue. Either way, it happens only rarely and lasts no more than 10 seconds or so each time, so not a dealbreaker.
Other than that, the phone is fantastic. Incredibly fast and customizable. People complain that Android isn't user-friendly, but I honestly find everything quite intuitive (with the exception of a few badly designed 3rd-party apps).
I get the same (even better in a few places) 3G reception on my Nexus then I did with my iPhone 3GS
The OP needs to take note of all the people complaining about reception issues have also NOT mentioned whether or not they have updated the radio.
Everybody sitting with the stock radio from the models released in January/early-February are going to have a lot more complaints than someone who has either updated their radio or bought a newer model that has the updated radio preinstalled.
i still say its just a conservatively calibrated signal meter! seems to match my other phones just fine even if the actual bars are showing zero bars, its still making the call and receiving the data. me thinks its just a software calibration difference...

Bro, you're entire post actually supports the claim that the carriers need to build out their networks more in this country! Obviously if the phone works great in an area like NYC or Chicago, but not so great in "sketchy" places like where I live (Toledo, OH), then IT'S THE NETWORK!

Well, I have had the exact opposite experience. I always have a better signal with my N1 than my wife does with her iphone in the same places.
My wife and I used to have identical Nokia handsets, and her signal was always significantly better than mine. Minute manufacturing variations in low power RF devices can make huge differences, and such manufacturing variations are a normal part of any manufacturing process, including cell phones.
Comparing one phone to another and declaring a problem exists with an entire line of phones is just silly.
Basically, there is no real evidence of a unilateral "Nexus One" 3G problem, even if some handsets have less than expected performance.
So if you want a Nexus One, get it, and chances are that if you are happy with your network, you will be happy with your Nexus One.

Test Proves I-Phone 4 Reception Issue Is No "Illusion"

http://shopping.yahoo.com/articles/...why-consumer-reports-cant-recommend-iphone-4/
I hate to defend the iphone but....
Most phones have similiar issues. Even on the nexus we all love. I lose 3G/cell signal all the time when I cover the lower half of my phone. This is something common on all nexus unless you have 100% awesome signal.
I think this is why this has not been discussed on this part of the forum
1) This is supposed to be about the Nexus One, not the iphone
2) All of us N1 owners know the N1 also has radio problems.
That being said, I'll still say the nexus is the overall best phone there is.

I agree with everything you said, including the last part about the overall superiority of the N1.
table: -75dBm
hand in front of me: -85dBm
next to my ear: -79dBm
That's my N1
But the news is for iPhone not for Nexus so not relevant dor this part of the forum (or any else i guess)
I dont know why people keep saying "this is common among all phones"
No its NOT.
1. You are never in direct contact with the actual antenna on other phones.
2. It usually takes a full grip to replicate this on other phones. Even then loss is not as significant as you are still merely muffling a signal not physically shorting the antenna process.
The iphone merely needs the gap bridged for it to dramatically lose signal to the point of dropping calls almost instantaneously.
The issues the N1 had were getting and maintaining a fix on 3G signals. A far cry from dropping endless calls because you were holding it wrong.

No, there are plenty of reports of a dramatic drop in signal strength when you cover the back of the N1 with your hand. Not exactly the same thing as iPhone 4, but still a signal issue caused by antenna placement, so definitely in the same ballpark.

Again, it's not even close to the same issue. On the N1, you can muffle the antenna a bit; on the iphone 4, you can actually electrically short it out.

This smacks of rationalization to me. People report dropped calls as a result of how they hold the phone. Whether it's because the antenna is "muffled" on the N1 or "shorts" on the iPhone, the result is the same from the user's perspective. In fact, the iPhone issue is arguably less of a problem because you can solve it with a case. I love my Nexus One, but I don't think we do ourselves any favors as consumers by rationalizing the phone's shortcomings.
Ummm...how is this related to Nexus One general?

The issue with the iPhone isn't that it has signal attenuation when held normally. All phones do indeed have that problem. The issue is the amount of attenuation. The iPhone 4 loses about 20 decibels of signal when held normally, the N1 loses 5-10 decibels, which doesn't mean that the iPhone loses 4 times as much signal. Decibels are an exponential metric, 10db loss is a tenfold increase/decrease, 20db is a hundredfold increase/decrease. If you use the "death grip" on the iPhone, you might see a 30db loss, yeah that's 1000x. That's why a lot of people didn't even realize that phones did this until now, the iPhone is particularly bad at this phenomenon.
There's a workaround to avoid losing signal when talking, and it's applicable with ALL phone with antenna at the bottom:
Just hold the phone top part when talking and keep hand off the bottom, but it's not possible when doing internet or messaging, or email.
When holding the phone for messaging, try to spread out fingers.
Sounds like Apple is trying to start a new FAD LoL...hope it doesn't catch on!

which is ridiculous and something a consumer shouldnt have to do. Its very annoying to not be able to hold my phone how it naturally feels to while watching/listening to anything streaming.
its really not that hard to fix this, just make a vertical antenna that way you address the heath hazard of an antenna next to your ear, and still not sacrifice much signal.
Wow, another feature that Apple will try to pass off as being first. HTC was the first to have dropped signal, dammit!!
(Tongue in cheek, guys. I realize the seriousness of the iP4's reception woes is much worse than the N1's.)

There are reports of a 20dBm loss in signal strength from the way you hold the Nexus One:
If you go to Settings -> About Phone -> Status you will see a display for "Signal strength". When my phone is sitting on the desk, the signal stays consistent. However, the second I touch my phone, the signal drops up to as much as -20 dBm. I am able to replicate this test every single time, whether the signal is incredibly strong or weak.

Google's "solution" was basically the same as Apple's -- i.e., hold the phone differently.
Weird, my Nexus One is just fine...........................
WRONG FORUM. Who cares.
Thread moved to OT.
what i specifically want to know is WHY is the nexus' antenna so sensitive compared to other phones. all my nokia phones would lose signal too when covering the antenna, but it seems like nokia and other phones use a moving average to calculate signal strength, over a period of the last 10 secconds or so. so that when the signal is blocked, it takes a few seconds to even start to drop. but the nexus almost seems to give dBm in real time, with no moving average at all. cause the dBm can drop intantly when blocking the antenna.
this is why i try to say that HTC just uses different bars, but the signal reception is no worse than other phones. it just shows in real time.
anyway i was at ATT store yesterday, and all 4 iphone 4's drop from 5 bars to 1 bar just by touching the lower left side. not even squeezing, just lightly pressing it. all 4 units. so what are these new phones doing with antenna that causes them to be so sensitive?
also, about the nexus, we have to think that because the nexus is only 9mm thick, the internal antenna is only seperated from our hand by barely 1 mm or so. so we too are detuning the antenna. its not a short like iphone, but close to it.

[Q] Droid 4 GSM/UMTS Signal level?

Hello, has anyone compared signal levels of Droid 4 to 'real GSM/UMTS' phones?
I've been checking the signal level with android software BestPlace, best I've accomplished is -61dBm, and it's often -80 or smth. I've also never achieved the phone to show 5/5 on signal bar, always max 4/5.
With any other phone I can get decent signal everywhere, as the D4 drops out really often on highways and places with worse reception.
Obviously you can't wait this phone to have as good antenna as real GSM phones because there needs to be antenna for really wide range of frequencies.. But still, any way to make it better.. ?
IMO the 3G-GSM handover is really slow and does work like early 3G-phones.. Very slow switching from 3G to GSM and breaking calls during the switch.

I have the same problem, and despite extensive googling have not found a solution yet.
I tried everything I could find and I am now considering a custom rom.
Sadly also the custom roms don't seem to pay much attention to GSM/UMTS reception, but that search was not extensive yet
Netherlands / KPN
Same problem here. I've two droid 4 and both have a much worse signal strengh than cheep gsm phones.
At the moment i'm trying some build.prop tweaks.
Did you already try something (e.g modified radio)?

How much does cell signal affect battery life?

I'm on Arman's infinirom right now, and it is absolutely amazing in terms of performance and stability. However, I'm still falling to see any battery life improvements. Right now the best screen time I can get is 4 hours screen on over the course of two days. No gaming, just flipboard, music, and web browsing. I've tried to emulate everyone's settings on here, but to no avail. I did realize that I'm in a rural area with very weak signal. Not just data, but actual phone signal. Would this happen to be the issue?
Here's a shot of how weak signal is here :
Sent from my XT890 using xda app-developers app
Your phone is always hunting for a signal, and the weaker or more unstable the signal is the harder it’s going to work to find and keep latched on to it.
It’s for this reason that if I’m on a long train journey across open country I put my phone in to flight mode until I reach urban areas to conserve the battery. One thing I don’t like about the RAZR i is that it doesn’t hold a 3G signal anywhere near as good as any of my previous Nokia's. I’ve used Three’s network for many years with no problems until I bought the RAZR, and as Three doesn’t have a back-up 2G network sadly I’ve had to switch carriers because otherwise I’ve been extremely happy with them.
Hope this helps.

Cellular strength and throughput

We know how much you like to stream, ahem, "videos", and so cellular data is mega-important. Rate this thread to express how you think the LG V20's LTE performs. A higher rating indicates that it's fantastic: throughput is excellent and signal strength is top-notch.
Then, drop a comment if you have anything to add.
Unfortunately, the signal strength is really poor for me
Good signal for me, Lte slows down to less than 2Mbps down while my s7 is doing 34Mbps avg. Im on at&t.
Not enjoying the quality I'm getting, even at home. 2 bars average, and this is in the Dallas area.
Worse than my Note 3, so I don't blame AT&T.
Glad to know I'm not the only one with speed issues. I was thinking there was something wrong with my phone.
I have issues indoors at my job but my Note 7 was the same way too at my job
A lot better than my Note 7. I tested this morning because I am finally getting around to setting up the phone the way I like. It tested at 80/16 which the Note 7 would only speed test at 23/12. This was at home.
Saw a report that the S7/Edge got an update to support 4x4 MIMO and 256QAM down and 64QAM up
Also supposedly the V20 supports this but hasn't been turned on for us (seriously WTF)
http://www.androidpolice.com/2016/1...-mimo-256qam-technologies-faster-data-speeds/
From I what I have read on Reddit from posts by Qualcomm engineers, the LG v20 does not support mimo. It lacks the additional anttenas for mimo, though it does support 256 QAM. I was tempted to get the s7 edge, but AT&T doesn't support MiMo or have any plans of implementing it in the near future.
I'm always at 1 or 2 bars. I often get "no service"
Most of the time I get 0 bars with an X, or full bars with 4G but no LTE, where i used to get LTE with my previous phone, I think this phone has a weak antenna
I need some kind of hardware mod. Anyone know where is the antenna in the phone?

I have the opposite experience, I get better service with this phone. Maybe yours is defective.
Sent from my [device_name] using XDA-Developers Legacy app
I'm with the 1-2 bar group. My Nexus 5x and Samsung S8 are guaranteed to have 2 more bars than my V20, no matter where I go. I also get the spinning circle near the signal meter indicating it's searching. I've downloaded several apps to confirm my suspicion that this phone's antenna(s) suck. I like the phone, but signal is important when it affects your ability to communicate, not to mention drain on battery.
I think a phone of this size shouldn't be any of bad reception, especially with so many metal contacts within its cover, which must act as antenna.
i have really bad / unreliable reception.
i rooted the phone.
might it be a firmware problem? could i flash it? i believe the firmware that was linked in the instructions was for canada... i'm in europe germany
right now i've got the Alpha Omega ROM installed.
Purchased an AT&T version of the v20 off Ebay h910. What I have learned is the antennas are in the polycarbonate end-caps. GPS would not work for me at all on a clear day outside. Found a thread on the Internet that identified the problem, some replacement end caps do not have the antenna contacts in them. Google "becareful_buying_the_top_plastic_bezel_of_the_v20" for the thread on the fix. I found an additional thread on fixing the call reception but it did not work for me, search "v20-signal-issues". Hope this helps as I spent hours and hours trying things until I found the gps fix. The GPS is in the top end cap confirmed, the 3g is supposedly the 3rd contact in the bottom end cap but can't confirm.
I still have yet to identify my horrible signal strength. The antenna connectors on mainboard were just there with no plugs. Imma check tomorrow if my phone has this stuff in top and bottom caps.
