Call interference - HTC U11 Questions & Answers

Hi,
I am very happy with the U11, except that I can hear interferences when on a call sometimes. It is that pulsing noise you hear when you hold a phone near a speaker, I think it has something to do with electromagnetic shielding? Anyone else encountered that or do I have a faulty device?
Cheers
jan

If your signal is poor you'll get the same. Carriers that rent lines from bigger carriers are suspect. My u11 is fine on 02 but crackles on Asda (EE subsidiary)

same mine

Heard that noise while calling someone, but im not sure if its signal strength related because i have 5 bars h+ (no lte bought)..dual sim btw
edit: im only hearing it while charging, dunno if its fast charge related

There is no iso standard for signal strength. You can have full bars but have a crappy signal. Signal meters should run on throughput but that'd eat data.

weak signal with gsm

halo all, i come from hongkong,
i have my d2G running GSM/UMTS signal, and also the call quality. I get 2 bars or sometimes only 1 bar as signal strength when set to GSM/UMTS.
even i set is to global, it doesnt improve much.
what is the solution
That's how it works unfortunately. In GSM mode it shows signal normally. It is UMTS mode where signal is always shown as weak (despite signal readings showing ok in settings/about).
Despite the low signal indication, phone doesn't seem to suffer from that. On 1 bar I get 6+ Mbps download speeds and I never had a dropped call or even degraded call quality. It could be a purely cosmetic issue (inaccurate signal strentht display).
I only get 4 bars in UMTS mode when facing the tower within 100-150 meters at most...
Good to hear that, I suspected the same thing when I saw the signal bars on D2G and compared the speed with my N1
so the speed is as fast as your n1 , even it got only very little signal shown?
yes its more or less the same.

Call Quality and Signal Reception

I live less than 3 miles from Center city Philadelphia and I get terrible cell reception. My radio goes nuts constantly trying to keep a stable radio signal. It jumps from H to H+ to LTE constantly. I can stand in one place and watch it jump around all day. If I force LTE, LTE just drops out constantly. What is going on?
I have a few friends who all use the same carrier(T-Mobile) with different phones and don't report the same issue. I even have a buddy using a Gnex and he gets better reception than I do. Call quality is not very good either. I was making a call while walking home from class and had the other persons voice drop in and out when the wind started to blow. I dont believe that Wind was effecting my call. That makes no sense, but there was a correlation that went on for 20 minutes.
Anyone else having call quality/ signal strength issues? I am not talking about your data speeds, we have a thread for that. I am talking about tower connectivity and stability .
I don't use my phone for calling, but I'm trying out T-mobile in Janesville and Beloit Wisconsin and I notice that my signal bounces between GPRS, EDGE, 3g and H constantly as well. I have no other phone on T-Mobile to compare to though. Granted all signals have 1-2 bars in most places.

LTE poor signal?

Hallo, Vodafone Italy still not offers LTE coverage in my city, but there are some cells that already have it enabled.
I noticed that when I'm under 4G, my signal never got past 2 notches.
So I ask to who is covered: is this right or do I need RMA?
Thanks...
I'm supposedly in a very strong LTE area and I usually see two bars. Occasionally there will be three bars holding steady but rarely do I expect to see four (out of five). My speeds rarely change from 16-18 up and down (downloads always faster. Zero packet loss on T-Mobile. My Nexus 4, on the other hand gets low speeds and between 2-4% packet loss.

Are you talking about the signal bars in notification area as "notches"? Trying to see if thats what you said. If so, the signal bars do not dictate the LTE strength, just cellular call strength. The LTE download could still be great even in no signal bar areas as well, signal does not influence the data strength nor does data strength dictate the signal quality via the bars. Since the phone has to turn off LTE to "switch" to 3G in order to make calls, the "switch" may have something to do with the bars.
Thanks, that's exactly what I wanted to know! And, yes, Italians call signal bar "notches"...

Phone Signal Strength drops considerably during phone call

Does anyone else have this problem and if so are there any fixes available?
I have fairly good cell signal within my home (around 95db), in the past (event when I first purchased my Pixel) I would never have any issues with calls being dropped but within the last 2 months I have noticed that when I use my Pixel normally (not on a call) the signal strength is fairly normal, but as soon as I answer a call the signal strength drops off and more often than not the call drops. I've had to start making sure whenever I am talking with someone I have to be near a window. My wife has a Samsung S7 and this does not happen to her.
Does this happen with anyone else?
Thanks so much in advance!
When the phone is idle it connects to LTE network but when you place a call it switches to HSPA network, that's why your reception drops down. At least that's what happenes on my phone.

Let's Finally Solve This Call Quality Issue

Many of you have seen the multiple threads on multiple forums about the call quality issues with the Pixel 3 and 3XL, so I won't dig into that any further. Instead, I am asking if those who have issues can list the signal strength as reported by your device in the area where the call issues occur?
For example, my wife and I only had call issues at our house, where both of our devices registered -115 dBm of signal strength. This was not a problem for our Pixel 2's. When calling from my job, the issue was far less frequent and the signal strength is approximately -100 dBm. Finally, we received a signal booster from our carrier for the house and the call issues went away completely, measuring -80 dBm.
Based on this, I can only assume the Pixel 3's hardware is not holding on to signals as well as other phones and I need your help determining if the problems go away above a certain signal strength threshold.
INSTRUCTIONS:
1. Open the stock phone dialer app
2. Enter the test menu by dialing *#*#4636#*#*
3. Select "Phone Information"
4. Find the "Signal Strength" line and report the value you see.
Once again, please only list yours from an area where you experience consistent call quality issues.
Hi,I'm having call quality issues on my Pixel 3 with -108 dBm of signal strength
My third pixel xl. All 3 of them never had call issues. Other issues yes. Thankfully calling is good
Semi-related question. I'm on Project Fi. When I check the Phone Info "wifi calling provisioned" appears to be off and greyed out. When I check Settings it's enabled. My wifi signal is very strong, I'm sitting about 10 ft from the router. Not sure how to interpret that "provisioned" status. Also, wifi calling could theoretically mess up the stats from your cell signal strength data.
I have had my pixel 3xl for a week now,
And I must report that for me there have been no call quality issues whatsoever.
I'm on 3 (UK)
Signal strength: -84 dBm to 56 asu what does it mean?
I don't really have any call issues but my signal is 115-118 inside my house
If you're in an area with poor signal and you're using VoLTE the static noise/buzzing will occur . It's been pinpointed as a baseband/kernel issue the version on the 3/3XL's are incompatible with certain towers. In areas with good signal the buzzing/static won't be there over cell. If you're in an area with poor/mediocre service turn off VoLTE and to make calls on 3G and there will be no buzzing. Sadly the issue still persists with WiFi calling though.
I have more drop calls on this device then any other. Mostly driving, gotta be tower issues. My other phone didn't have this issue, but I'm with Verizon now I was with Sprint.
Tmobile -109 no bad call quality and decent data when not in super old building.
-105 for me
happening on BOTH pixel 3's on verizon. had pixel 1's before and NO issue. other users, including samsung and iphone on same plan, no probs. signal at -95 and -93 in 2 locations that I have had problems. I don't believe just signal strength, as both have good strength (tried both cdma and lte) and still issues. not all the time. funny thing, I was on conference call with both verizon and google when audio on my end just dropped, I could not hear anything and they could not hear anything but calls still connected. another time was on phone with verizon and she said (yes..she said) was very choppy. that was 1/9/19. called back 1/15, "John" then scheduled him self to call me back 11am yesterday (never called), now back on phone with verizon and she just had me fact reset phone. she said next step, new sim cards (I had not thought of that) and then replacement. Hate to say it, almost ready to go iphone.
Idk still no issues here

Is that the approximate signal strength you have where you experience call issues?

This is a very similar experience my wife had with T-Mobile. I have the same phone but don't have the problems, so it isn't a network issue, but the problem did go away once we started receiving a stronger signal with the booster.
Keep working with Google and they'll send you a new device, unless you purchased from Verizon and they'll make you jump through hoops.

I have it on my Pixel 3 expecially in my office where the signal is not good. I did some test and I've noticed that the problem goes away if I switch to 2g (maybe for the better signal quality) but after 5/8 minutes the audio goes away, the other person doesn't hear me while the call stays open.
While testing I've also noticed that leving the phone in LTE with low signal in 4 hours (with podcast listenig and varius phone calls) I lost 40% of battery, in 2g I lost 20%.
My thought are that the device has a radio problem, high battery drain and call noise with low signals

Update: 1/24/19. After fact reset and new sim card still same issues. Verizon sending out 2 "like new" pixel 3's. I read one post where user and wife both on 5th! RMA pixel 3 and same issue! I mentioned to Verizon rep and questioned option to switch to iphone if happens with "new" phones, she said not normal but there can be exceptions. Hope I don't end up blue in the face.

Good luck to you!
Guys can you boot into safe mode and see if the callaudio problem goes away?
