3 phones, same location, same operator, 3 different speed navigation - Hardware Hacking General

How do I explain this?
I did an experiment with 3 phones (sony ericsson live with walkman, galaxy nexus, huawei vodafone), all located in the same space (side by side), all with the all inclusive option wind and navigation 3g.
I launched at the same time the application speedtest on all phones and I had the results veramenti distant from each other. I repeated the experiment 3-4 times.
results:
huawei: just over 1 meg
galaxy nexus: a little over 2 mega
sony: over 5!

The modems I would think is the explaination

BaseBand I would say
and ofc phone signal reception...
I even had an xperia mini pro sk17i and my girlfriend had the same phone, both on 3 with super internet and my phone didn't receive signal at all when I was not under an aerial... (euphemism)
Sadly we had the same baseband too, so it was an hardware problem i guess..

Yeah i also think it is the hardware. If you remember iphone 4, that had a bad signal if hold it in the wrong hand and plus companies always try to save money through using cheapest material, i wouldnt wonder ...

Hows signal strength

I checked signal strength in store. I compared my sg4 to note3 and lg g2. The note 3 was a stable 108db every now and then it fell to 106db. My sg4 106db to 105db. The lg g2 did 101db.
I want the note 3 but I cant purchase until after an update proves it software related not hardware related

Well here's my story. Have two note 3 units. One is on. Att the other on t mobile. Both are on att service plans.
One phone shows -111 db other shows -106 db side by side consistently. My t mobile on att shows less signal compared to wife's att note 3. Is mine faulty? If don't know , just observation.

maybe its a frequency thing if not then maybe one is fault or that side by side the few inches make a big difference

Also bear in mind the lower the minus Db the better signal.
"Also bear in mind the lower the minus Db the better signal."
Another way of wording that is the closer to ZERO the better the signal.
Anyways I've found the Note 3 to be pretty bad... Seems like this phone has a pretty weak antenna in it...

Perhaps as bad as the S4? Well for me, yes. Roll on 5.7 inch iPhone LOLzzz. Once I went droid I cannot go back!

GPS and mobile died after 10 hours of nonstop use

I have a stock Galaxy S4 google edition.
I drove from Chicago to Philadelphia and used the phone as GPS via Google navigation. I was connected to LTE from T-Mobile.
After I arrived and reboot the phone it stopped getting mobile network (no bars), cannot make any calls and GPS cannot fix the location anymore (in fact gps icon doesn't appear anymore when I run google maps).
The sim card works fine, as I checked it at T-Mobile office and I do have a valid plan and etc.
I tried factory reset, via settings and via boot menu, but nothing changed.
Luckily google agreed to send a replacement.
Did anyone have this kind of issue before?

Although im a samsung owner but I believe that its not a quality devices, I owned 5 HTC devices before the S4 and I can tell you that compared to samsung htc seems like a real genuine device, I just bought the S4 for the smart/air stuff as a change, its a good device but no quality whatsoever

Not sure why you think that Samsung devices are low quality, if you are thinking because its plastic feels cheap then I disagree with you. I had many friends using Samsung devices such as the S3 and Note 2 and fewer friends owning HTC devices. However, my Samsung friends except for one whose phone cannot switch on for no reason had no problems with their phones. However for my HTC friends, one of them who just used his phone barely 1/2 year is having problems with his power button. The other also had problems with his power button and recently his LCD just refused to switch on.
As for me myself, I owned S1, S3 and now S4 and I had no problems with any of the devices. All of them are still working perfectly. I also owned a LG Nexus 4. That device feels more "expensive" than any Samsung devices. It feels more solid but however just using it like 2 months. The power button spoilt. Then I fixed it myself and about 6 months later, the touchscreen's digitizer starts to spoilt and due me giving up that phone for an S4.
This is my second Galaxy S4 GE btw. The first one had a malfunctioning proximity sensor. Basically when you make a phone call holding a phone on a distance, the screen goes black immediately. I returned it to google for a replacement too.

Speedtest Apple 5s vs Galaxy S4 WTF??

I use an Iphone 5S for work, and have a Samsung S4 for personal use, I overwhelmingly prefer the S4, but . . .
I did an experiment today, phones sitting side by side, both on LTE...
Iphone 5S - 24.66d/14.44u, ping 18ms
Galaxy S4 - 6.4d/1.12u, ping 119ms
What is going on here? Is our modem that bad? Anyone have any tips to improve speed?
There is no real way to improve speeds. There are some "tweaks" that exisit somewhere for 3G idk about 4G. It could just be that at that certain point when you ran the speed test the IPhone had better signal than the GS4.

They were sitting on my desk and I ran them both at the same time and to the same server. Both were showing two bars at the time.

Did you look in the speed test app that you were using on each phone to make sure that they had connected to the same server?
You can't base anything off of a single side by side speed test. You should do the test several (at least 10) times in different locations and at different times of day. Record the results and take an average.
At the very least twice when you are doing so to check for discrepancies.
Anyway, I have never had an issue with the LTE speed on GS4. Just ran a quick test and got 21 down, and 6 up. The LTE reception is kind of bad around here too.

[Q] Do you Have A second Phone?

Just a bit of fun as we are getting near Christmas...
Now we have got our Note 4's & enjoying, I wondered how many of you have a second phone that they switch to now & again?
Do you use a second phone?
If so, What do you use?
I have the Moto X 2014.
Have SM-P605 Tablet and iPhone 3GS and iPhone 4 ass well, sold my iPhone 5 and use now my Note 4
I have a HTC One M7 as the contract still has a couple of months to run and a Nokia Lumia 820 for my work phone
I have note 4 now but i would like a note edge for my second phone
Also have and iPhone 5s. Use it for all my music.
When it comes to output from 3.5mm jack note 4 is no where close to iPhone.
Also I am having issues with camera. The pics from note 4 are blurry and not as sharp as iPhone.
Have tried all troubleshooting tips for camera but no luck.

Well getting used to the Note 4 but I still have my iPhone 5 for the odd thing or two. It's pretty much been downgraded to an iPod.
I have an old LG P925, the big old 3d can phone that I got from aunt years ago. It's quite laggy and the battery life is awful, plus it hangs up while texting or receiving calls once in a while (the microphone turns off once in a while during calls).
I only keep it because it's on the network my family uses, while my note 4 uses the network most of my contacts use. I also bring out the LG when I take public transportation, the Philippines isn't a safe place for fancy phones out in the public
I have a OnePlus One on it's way.

Galaxy note 4 Android 5.0 POOR Signal

Hey Guys,
I Bought my Galaxy Note 4 a few days ago " In Kuwait - Arabian Region " and I updated it to the new Samsung release Android 5.0 for Note 4, and I have been having POOR/SLOW Signal on my note 4 compared to my old Xperia Z1.
I get low signal and slow data internet I have checked with my coworker and he have the same issue on his phone, but an old Mobile Phone such as the Xperia Z1 with lolipop doesn't have this issue :'(
Does anyone have this issue or know how to fix it
I tried to :
Hard Reset x2 times
Format Phone x2 Time
Cleared Cache 3x Times
Kies firmware recovery tool ( One Time )
And all of them didn't do anything or improve my Signal
Having the same problem here with BOE1, 2 & 3.. it's modem related i suppose.. if you're still on BOC something don't update to any of the BOE versions.. try flashing the BOC5 UAE firmware.. had the best reception with it
I have the same problem in uk. My iphone 6+ was great everywhere.

This has been my experience with the Note 4 as well (I've had it for over 6mo). Whenever I use it I miss/drop calls frequently and data connectivity is spotty at best. Unfortunately if it weren't for the continuously weak signal, this would be a perfect device for me. Even my Nexus 5 has a significantly better antenna/radio.
Agreed. Last week I was on a picnic in the mountains and all of my friends had signal/reception on their phones (moto g first gen, htc 8x...), except for my note 4; not to mention, we have the same carrier... Was quite disappointed tbh. Oh, and I am still on BOC3, as it's the latest official software here.
it's modem related i suppose..
Same issue after upgrading my 910f to lollipop, though I had the same issue with a LG G3 after upgrading that.
I'm in a weak signal area most of the time, and have gone from ~1% time without signal to ~15% without.
That is strange? Have you tried restoring your Note 4 to it's base factory settings?
Same here although if I switch off 4G it's better.
Hi, i change my S5 to the note 4 and doesn't notice better performance, battery last the same.
But i notice reception is worst than the S5.
Because im all day data on and today i see only have 2 bars at home when S5 is always full.
Really don't know what to do.
Top phone S5.

It happens to me too. At first, I thought it was a new feature of the Note to save battery or something like that, but now I see perhaps is a bug, and a common one.
Im now changing for a new one in the store and if it does the same i will change for the s6 or lg g4.
has anyone who has updated to 5.1.1, and was having this issue, seen an improvement?
