Hi, I have brand new E52. Until now I did about 10 GSM calls. Everytime other party complains that hears me badly. My voice at other side is very quiet. This happens mostly when I am outside in the street walking or entering the building/underpass. I can hear other side perfectly. Quality of the signal coverage in my area is good.

Does anybody have same experience?

[nidooo]

i do.

This is the most terrible Nokia I have used, 

I just used it 7 days, but I will try to send it back, ask some help

I like this phone, but the quality.. no friends of mine can put up with it

I don't have this problem so far.  You mentioned the issue was when you were outside in noisy environment.  That reminds me of something.  The phone has noise cancellation technology that reduces background noise from being transmitted over to the party you're calling.  The manual says that you shall hold your phone with the bottom mic section reasonably near your mouth...

I guess that means as opposed to let's say you hold your phone in a full up right orientation with the earphone next to your ear while the bottom mic would be a distance away from your mouth.

i have 2 e52s and both have the same problem that is driving me and the people on the other line insane. they are both less than a week old and infact one of them has a much higher rate of reoccurance on bad quality calls. people on the other line suddnely cannot hear me properly for a while.

i think its an issue with the phone make since both of mine have it

[marsark]

I can confirm another phone with this issue. My friend has bought one and have same problem. Definitely this is a bug and have to do with noise cancelation.

[isaahmed]

i had it also,,,and i though that i was locking the micrphone area

all ppl some time say we can not hear you will

as i was far away

so this is issue in the hand set or softwer?

[marsark]

IMHO, it is a firmware bug. I hope, that some NOKIA personel will read this thread and push some fixes to next firmware release. Now, it is a pain...

[hale]

Now I compared this mobile with my old Siemens...Yes - the quality is realy bad. 

I was using UMTS. but when it lost UMTS and switched to GSM....

Horrible hisses and zummings appeared! This is UNCURABLE problem of  RF part, I think. It is interferrence between tranciever and voice amplifier.

Nokia is greedy on screening plates! Shame on Nokia! :-( 

There also fixable SW problem in noise gate filter. It cuts voice to often. It cuts incoming ambient noise so I sometimes think the caller has hanged up his phone. Very irating.

It vas not so obvious on street with UMTS. But at home with GSM it is Very-Very bad :-( 

!!! The noise filter must be made turnable off by user in settings menu !!! 

 --------------------------

To mention. People hear me much better then I hear them.  I mean outgoing quality is superb.

But incoming zummings, hisses and gatefilterblackouts are very bad :-(

NOKIA! PLEASE! Let me disable noise filters for incoming sound !

Do not buy this phone !!!!!!!!!!!!!

really bad voice quality. I buy and use this phone in Hong Kong. but experience same problem with others country.

I experienced exactly the same problem. Many cuts in the Incoming calls.

[gviewfinder]

hersvim, I don't think e52 cuts incoming ambient noise.  Unless you mean the caller to you is also using noise cancellation enabled phone which cuts the ambient noise.

[hersvim]

hi gviewfinder,

I quoted the text from hale's post, and I had the same experience.

I do hear a lot of cuts in my calls, especially VOIP calls.

[hale]

I don't use VOIP. My experience is based on GSM and UMTS calls (in my area they are cheaper than packet data Internet transfer)
If the quality is very good (UMTS<->UMTS/UMTS<->terrain line) and the ambient sound is minimal – those cuts are negligible. But if it is highly compressed GSM or call, for example, from a street, I can't hear person's voice because of this filter. Another example is for people calling from a noisy office. Ambient noise is cut in such way that I think the person has hanged up the phone.

This could be related to the noise gate adaptive level algorithm. It could be frequency dependant, and you know that in advanced VOIP codecs and in GSM thee are powerful frequency filters inserting heavy distortions in the noise spectrum. So the adaptive level can be calculated completely wrong. (just a guess)

Incoming sound MUST NOT be filtered at all! This is crime in business-class!

Overall there are many complaints on this phone's network coverage and call quality. It has nothing to do with the Network Mode in the phone, with Operators and their SIM cards either......I've been using it not a whole week and have already noticed 1 occassion where the person I called couldn't hear me & the call was breaking.

[hale]

Yesterday I had the same problems with support team of my operator. 

I've tried to ask some questions on high speed internet options... and they didn't hear me well. neither I could understand every ther word. 

Nokia! please! Let me disable active noise filter!

[bummer]

YES!!! I have the same problem. It would seem like Nokia really screwed up by releasing this phone without testing the most basic function of voice/call quality. It is bloody hopeless. The most f***** up phone I have ever used! Nokia, get your act together otherwise I'm going to stop using this phone and recommend others against buying any Nokia phones.

[marsark]

Now I have E52 for 14 days. I have found, that this phone is terrible piece of **bleep**. Hope Nokia personel will read this.

[olshevch]

Actually, I have opposite experience about sound quality.

Person, who I bought the phone for, had used N73 and confirmed that sound harmonics are more definitive and have more depth in E52. I use N95, but speaker on E52 feels better for me.

Opposite direction (from E52 to N95) also sounds much louder and better, than it was from N73 to N95, even in noisy places.

There are some bugs about this phone, but they are not related to sound quality.

I am not using this phone continuosly to be able to check signal reception quality.

"harmonics are more definitive and have more depth" 

Sound harmonics CAN'T have depth. That person is just saying pretty words to for your pleasure.

Extra sound harmonics (that creates so-called depth of the sound) are parasite harmonics that MUST NOT be added to sound. Rich sound is only good while it is original. Any sound depth enhancement makes speech less recognizable!

If you have N95, of course sound is great - the problem exists only on E52 as receiving side. Sound transmitted from E52 seems to be superb.
