S4 Mini duos I9192 very slow 3g speed

[fmohiy]

i've had an S4 mini duos fro 3 days that replaces my Note 2 as i wanted a smaller phone with good features.

before i got the S4 i made sure to check all the reviews and youtube videos and made a lot of camparisons on gsmarena.

Not a single site or review mentioned how terrible 3g speed is on this phone.

Check this comparison of HSDPA speeds supported by some device:

S4 mini i9192------14.4 Mbps
Note 2 n7100------21.2 Mbps
S4 i9500 -----------42.2 Mbps
Mega 6.3 i9200---21.2 Mbps

i made a side by side comparison with a friends Mega 6.3 phone using 2 apps,

speedtest
, average of 3 tests showed the s4 mini returned half the speed of the mega phone


netwrok signal info (on vodafone egypt)
the mega connected much more frequently on 14.4 than the mini, and with better network signal percent
the mini stayed almost all the time on 7.2 and only touched 14.4 for couple seconds then returned back to 7.2.

As both the mega and s4 mini have the same CPU from qualcom, i belive there is an either with the antenna of the S4 mini, which is shorter/weaker due to its smaller size, or the software of the mini is not yet optimized due to the dual sims/antennas

either way, i really am disapointed with the 3g performance of the s4 mini duos, which is a pitty as i love all other aspects of this phone.


Did anyone else face slow 3g speeds with the mini, or am i the only one?

!

yes it is slow also for me too.by this reason i sold my phone and go back to S4.

hi,

I'm facing some strange issues with the mini duos.
while on 3G, email client is not connecting for sync, and facebook messenger is not working properly ( when a send messages, it's saying sending... and takes an eternity to send it ) although internet browsing is working fine and even faceboko wall browsing is loading fine, also google maps is working, so there's internet connection definitely.
i did a speed test today with radio opt, and seems to be ridiculous speed
dowload: ~400kbps
upload: ~100kbps
ping: not working..

I'm wondering what could be the cause ...
are the email client and facebook messenger using different types of connections to internet browser, google maps and so on?

On wifi, everything is working fine!

Regards,

Robert.

On the back of my S4 Mini Duos box it clearly says HSDPA 21.1/ HSUPA 5.76

would you please try if your device behaves the same way as mine on 3G , see my previous post?

Thank you!

I never got my phone to connect past 14.4 but you are right it mentioned 21.1 on the box.

Still it is waaay slower than my note 2 which was also 21.1.

 

[Rew64]

I've just done a speed test. See attached picture.

So that puts it firmly in the 14.4 Mbps bracket. Maybe Samsung are telling fibs

can you download "network signal info" app from the play store and tell us if it ever connects above 14.4?

Mine doesn't even in very strong signal areas.

i get some strange behaviours also, but for me the phone would show the "H" signal and "network signal info" would clearly show connection on 14.4 Mbps, yet i don't have any data connectivity and speed test would just show "communication error".

i would stay like that for a couple of minuted, discconnects and reconnects the HSPA connection by itself and then start working fine.

I still belive it is either a weak antenna by design or immature modem drivers. I'm hoping it is the later and samsung would fix it by a firmware update.

PS: i've had a note 2 for one year and before that a note one for another year and neither one of them had similar issues with data connection.

I've downloaded the program via WI-FI but I will have to wait until I go to work later to test it on 3G as I live in a very rural area with only 2G coverage.

I've also contacted my service provider (3UK) and they say that the strength and speed of the signal is dependent on what part of the country you are in, big city's being the best.

 

[Rew64]

Here is the result of my test. It connects OK but it dose really depend on which area I'm in.

Here is the result of my test. It connects OK but it dose really depend on which area I'm in.

so the S4 mini duos chip has the ability to connect on 21.6. the problem again seems to be either hw (antenna design) or Sw(modem drivers) beacuse the S4 mini is consideraby slower than a note 2 or a galaxy mega 6.3 depending on personal observations and tests.

i've solved part of my problem by buying a second sim from anthother service provider "etisalat" that have better 3g coverage in egypt and use it on sim slot 1 only for data.

Now i get speeds a bit closer to what i used to get with vodafone on the note 2. and my vodafone data coverage using the s4 mini is hoplessly slow in areas where it used to be fine in the note 2.

where does that leave us??

should the S4 be considered defected because of its inferior 3g cabability in comparison with the handsets from a level up (s3, s4, the notes), or should we consider it as something that should be expected from a handset that is a category lower and with smaller screen size / dimensions?

do all Samsung handsets of screen sizes 4.3 or lower face the same issue?

 

[mar10o]

I think it's only a modem drivers problem.. AMH2 software is really buggy for me.

What firmware are you on pls?
I m using my duo in the UK and 14mb it's max I can get, although Note 2 with the same sim card gives me 21mb (3 UK)
Im currently on rooted MF7, the phone comes from Emirates though

The phone is a week old and I'm using it on the 3UK network. Everything on the phone has UAMF7 at the end. Not rooted.

I've only managed to get it to connect at 21.1Mbps twice and most of the time it's at 14

 

[qwerty1q]

I have never got signal above 14mb, Note 2 keepa saying 21mb all the time with the same sim card, maybe it's firmware fault?

The only difference I can see is in my screen shot I have the + sign next to the H in the top bar when on 21.6Mbps and yours doesn't, plus you have the R for roaming in your top bar. That normally means your roaming on to the Orange network (EE now) because it can't pick up the 3UK network.
What is the net operator number?

 

[Rew64]

I've been in Birmingham UK all week and the phone constantly connects at 21.6Mbps so I think it's more network related than the actual phone.

 

[qwerty1q]

Hmmm interesting, I live in Manchester and everywhere around here I have 14mb only. Do you own a duo s4 mini?
What's your firmware kernel etc please
What's your network? Mine is 3UK

Yes i own a Duos S4 Mini I've had it about 3 weeks now. Not rooted all stock as it came out of the box.
I'm on 3UK the same as you.
When you see the + sign next to the H (H+) thats when it's on 21.6 Mbps
See file below for the rest of the info.
