[Galaxy S 4 Q&A, Help & Troubleshooting] follo:
Probably you right.

Reading here, this seems to be an little issue but I think it's a global problem. Maybe people think that's a problem related to a poor carrier signal.
[Galaxy S 4 Q&A, Help & Troubleshooting] Bulkatos:
Hey folks,

this is not just a little problem. Look at this german thread, where there exact talking about this issue: http://www.android-hilfe.de/samsung...t-netzempfang-bzw-wechsel-zw-lte-umts-59.html

My firm use this phone for most of the employees and asked me to research a solution. ATM it seems there is no one, isn't it?

The option to disable LTE is no one, because the employees use it very often and it's necessary for there business.

Should an modem.bin update solve this problem?

greetings Bulkatos

Wow, that's pretty bad, at least I know it's not my handset's hardware failing. Samsung needs to fix this ASAP, my phone hung up on a customer 3 times on Monday!

On the plus side, MEA seems to have improved this. I am still seeing some red bars in the battery log so I think it's still disconnecting from time to time, but I have not personally ran into those random but consecutive disconnect / reconnects that I would get with ME1. However, I did do a complete wipe / factory reset as well just to make sure something wasn't broken with my stock ROM.

I've only run MEA for about 24 hours, so it's too early to get excited. Here's to hoping that SOMEONE at Samsung is noticing this awful bug...!
[Galaxy S 4 Q&A, Help & Troubleshooting] follo:
I'm using MEA firmware (ITV no brand) since yesterday morning and the 3G/H+ switching problem seems gone away :good:
[Galaxy S 4 Q&A, Help & Troubleshooting] cmd512:
It's less here for sure compared to ME1, but it's still happening. Seems to happen more when the device is plugged in, unplugged, or coming out of deep sleep / idle mode. Something with the system power up that is causing some connection issues methinks.
[Galaxy S 4 Q&A, Help & Troubleshooting] follo:
I come from MDM and the behaviour is now different for me: previously the 3G/H+ switching didn't work very often, now I haven't had a single data interruption.

Is too early to consider the problem gone so I'm still testing the phone, but now I can keep the H+ mode on without big problems.
[Galaxy S 4 Q&A, Help & Troubleshooting] cmd512:
Totally different than what we're experiencing, our entire signal + data symbols disappear and show a circle with a line through it. The same symbol shown when there is ZERO reception.

It's almost like the radio hardware shutdown and restarted...
[Galaxy S 4 Q&A, Help & Troubleshooting] Bulkatos:
I'm a little bit confused. Which one is the working Firmware? Can someone post a link to the firmwares?

Would be great to give my boss a solution for this issue. Thanks.
[Galaxy S 4 Q&A, Help & Troubleshooting] AiMwasNeD:
Just my theory:

I believe it's not firmware related on the S4. Got that problem after flashing omega rom for the first time on my i9505. There it depends on the CSC backup wich save ur preferred network and restore as manually chosen,i think.

On "stock" odex or deodexed roms it fails when u start messing around in provider settings.

Or another possibility: This issue will be genereted by failed CSC installations while flashing a new firmware.

Did someone ever noticed that CSC wont change after flashing a new firmware, doesn't matter if FULLWIPE or NOWIPE.

After a 2nd / 3rd reflash CSC finally changed. Noticed that problem on the last GT-i9XXX generations.

Solution: (for me)

Settings -> More networks -> mobile networks -> Network operators -> select automatically
[Galaxy S 4 Q&A, Help & Troubleshooting] temiong:
I will keep an eye on this thread since I am having the same problem with my I9505. Anybody in this thread from the Philippines who experienced the same with Globe as your carrier? Anyway, the lost of signal only happens when i switch to WCDMA only mode.
[Galaxy S 4 Q&A, Help & Troubleshooting] echenze:
Happened to me too on my GT-I9500. I am not sure whether it has to do with the network or the phone and its firmware.
[Galaxy S 4 Q&A, Help & Troubleshooting] cmd512:
Sorry, but I don't buy it. CSC is only carrier specific codes, doesn't make the phone start disconnecting at random when using a different GSM network. That's the whole point of an international unlocked device, you can go to any country and pop in a SIM card.

MEA has improved this issue, but it still happens. I think the software needs to be fixed, or otherwise, it's a hardware issue.
[Galaxy S 4 Q&A, Help & Troubleshooting] joyo22:
I don't think this is hardware related. I am f4om Colombia and experience this issue almost everyday. I went to the US last week and used my phone everyday for 9 days with a T-Mobile sim card and guess what... phone never lost signal. It worked perfectly. Any ideas?
[Galaxy S 4 Q&A, Help & Troubleshooting] BJ van Beethoven:
Sorry to bump this back up, but I've been having this issue since flashing MEA on my i9505. Currently running the 4.3 leak and the issue still exists. Anyone know of a work around or fix (that doesn't involve disabling H+ and LTE)?

I use my phone for work and rely on 3G/H/H+ for travel, so it's incredibly irritating when the phone is constantly dropping signal/data connection.
[Galaxy S 4 Q&A, Help & Troubleshooting] REVERSiN:
Mate did you try flashing another modem that may suit you better ?

And did you do full wipes while flashing ? It might cause that as well...
[Galaxy S 4 Q&A, Help & Troubleshooting] BJ van Beethoven:
I haven't tried another modem, but I always perform a full wipe before flashing a new ROM to avoid this kind of thing.
[Galaxy S 4 Q&A, Help & Troubleshooting] follo:
I have to reply my post because after a couple of week without any problem, now my phone still loose the data connection when tries to switch from 3G to H+ network type.

I have the problem almost always in the specific area where I work and rarely in the other places so yesterday I sent a message with these details to Vodafone (using the specific android app made by Vodafone) because I think this is a radio cell related issue. Let's see if they'll solve the problem.

NEW UPDATE:

After I made a notification to Vodafone, the problem seems to be definitely gone in the area where I work. After that I think the problem is principally related to Vodafone.
[Galaxy S 4 Q&A, Help & Troubleshooting] BJ van Beethoven:
Switched my network mode from LTE/GSM/WCDMA to GSM/WCDMA only and the issue has gone...weird.

I tried a couple of different modems and even tried the GPe ROM but nothing fixed it, aside from the above. Network issue with Vodafone maybe?

[T-Mobile Samsung Galaxy S 4] xxjrsmith3xx:
ok guys I downloaded cpu spy and after using the phone for 10min my phone never hit above 1.5 ghz ... I thought this phone was at 1.9 ,I did a lot of testing and still couldn't get the phone past 1.5 , no wonder things are not as smooth as they should be. I also upgraded to the new firmware it is a bit faster but I see the phone cpu is always around 1.5-1.1 ghz not good to run as smooth , also if cpu the low I'm sure gpu as low why all the animations run slow.

Edit : was playing angry birds star wars check back cpu ran at 1.1ghz -950mhz ...

Edit2: so i ran a anTuTu test and finally it hit at 1.9ghz and it drop down to 1.6ghz and 1.7 ghz for a few seconds. I really feel if this phone ran past the 1.5 it be a lottttt smoother i mean a lot.. just my 2cents trying to help out.
[T-Mobile Samsung Galaxy S 4] screamingbox:
CPU factors

Listed CPU speeds are a maximum, a lot of factors play into that actually CPU speed you will see when running various apps.

Also, the CPU monitor reporting may not be 100% accurate, again due to several factors.
[T-Mobile Samsung Galaxy S 4] dtrwos:
Also for reasons spread around this forum (all the battery threads popping up after the 1st week with the devices in hand)

The default cpu speed governors are likely set to preserve battery and only kick into high gear when the need REALLY presents itself.

Ie to samsung a little stuttering is fine if it means the battery lasts an extra hour in most cases

Most custom roms have different cpu governors in place - designed in part to respond more quickly to system load and increase performance.

If you update to the new ota your will lose the ability to root again. There is a kernel update that isn't Mentioned

Hi,

I was wondering if we can turn off hsdpa to save battery life, i used to have a Captivate and we used this secret menú to disable hsdpa, leaving only the 3G which consume less battery than Hdspa and is faster than 2G, but i can not find this menú on my nexus 4, someone knows how to do it?

This is the link to Samsung Galaxy where they shows how to do it:

[REF] WORKING: How to disable HSPA / HSDPA for better battery life

Hi people.

One way to get longer battery life is to disable HSPA and just use 3G. 3G (UMTS) is not as slow as EDGE/GPRS but doesn't use as much power as HSPA.

Here's a quick comparison of *typical* download speeds:

GPRS: 48 kbit/s, EDGE: 150-200 kbit/s, 3G: 384 kbit/s, HSDPA: 1000 kbit/s

After some searching, I've found a method that actually works for our Galaxy S:

Go to the phone dialer pad and enter this code: *#301279#

Click [2] CHANGE HSPA REVISION

Click [1] RELEASE 99 (HSPA OFF)

Then you should see something like:

CHANGE_R99

HSDPA OFF, HSUPA OFF

Done!

Press the BACK button to exit, or press MENU button then END.

The setting should take effect shortly after you exit the menu. To be sure that the setting take effect, toggle Flight/Airplane mode.

You could store that number in your phone book or speed dial for a quick way to toggle HSPA.

The setting STAYS ACROSS REBOOTS!

If you want to enable HSPA again just go back to the same menu and choose [3] RELEASE 6 (HSDPA/HSUPA).

Just tested it with the XXJPP radio and it really works.

Longer battery life at last!
[Nexus 4 General] chrisrozon:
Quick way is Settings-More-Mobile Networks- Use Only 2g.

Better way is to install a toggle control app that let's you do it in one touch.
[Nexus 4 General] cas0404:
Thx, But 2G Its too slow, with this method the Hsdpa is off but the 3G still working so Its faster, but Looks like lg doesnt have this option or i can not find it.... Jet
[Nexus 4 General] chrisrozon:
HSPA is 3g
[Nexus 4 General] trek85002010:
Try this code:

*#*#4636#*#* :good:
[Nexus 4 General] vikramkhalsa:
Yeah the main way is to check "use 2g only" which would give you edge only and may save battery but yes it is very slow.

There is also a toggle 2g app which makes it more convenient, or you can use tasker.

Based on what I've read on the forums I'm pretty sure HSPA is 3g. In which case theres no in between.. if you go through the dialer menu you can choose wcdma/gsm which is 3g/2g. We're used to thinking hspa is 4g but its actually 3g since true 4g is actually LTE. Confusing, I know.

Please correct me if I'm wrong.
[Nexus 4 General] fernandezhjr:
HSPA/HSDPA is enhanced 3G. Sometimes referred to as 3G+. It is faster than 3G, but not near as fast as LTE, which is true 4G. I speak mainly for the AT&T network because I spent a lot a time with this on my HTC Inspire. AT&T invested a bit of money enhancing their backhaul to accommodate HSPA. I lived in a marginal area where my Inspire was typically on 3G but, by design of the device, was constantly searching and switching to HSPA and back and forth. This constantly drained my battery and caused dropped calls because it was switching towers when doing this. I ended up having to place a microcell in my home to alleviate this, since there was no way to do it thru the device. I'm not sure how my N4 would act today because I still use that microcell.
[Nexus 4 General] chrisrozon:
The OP was asking how to turn off HSPA. In the context of this phone, that's 3G. The next step down is Edge.
[Nexus 4 General] AshtonTS:
HSDPA has no more battery drain than 3G...
[Nexus 4 General] Phantom1275:
3G is not HSDPA, is UMTS. HSDPA is 3G+.
[Nexus 4 General] fernandezhjr:
True that. Considering this is considered a developers phone that is unlocked and unbranded, I'm a bit surprised at the limited band selection.
[Nexus 4 General] chrisrozon:
It's a 5 band GSM phone, what more would you want? Other than LTE, obviously, we've done THAT discussion to death :)
[Nexus 4 General] fernandezhjr:
I was referring to the ability to select the bands. When I go into the hidden test menu and try to select a radio band, I get a message that states "Unfortunately, the process com.android.phone has stopped". And yes I know this was done intentionally to hide the LTE band. My point was that I consider that somewhat odd. That is all. With previous phones I found the ability to switch bands useful for signal tests in my area, even though I couldn't always make them stick.
[Nexus 4 General] sigma392:
THANK YOU. I can finally enjoy fast (Fast enough for my needs) internet without the blackhole drain of HSPA+. 3g, UMTS, does not drain as much as HSPA+.

It's probably an NV Item in the Qualcomm radio. You would just need to find what value it needs, put the N4 into "modem" mode, and use NV Item editor or similar to change the value.

? Don't understand what do you mean. This option is really important for me therefore I need an alternative working method to change it... Anyone? Or an alternative method / app to enter the HSDPA control menu! Thanks a lot!

An other way is to use the ro.ril.* settings to set the values you need, but if I enter the settings in the build.prop, my n4 gets a bootloop. So?!

[Nexus 4 General] Johmama:
I was about to reply to this post and correct you, but then I said to myself "Hmmm... I don't know all there is to know about this. Let's do some research before responding!" Sure enough, you are correct. LTE is not true 4G, as required by the 3GPP's requirements. Only due to marketing pressures did they allow LTE to be called 4G in the first place (kind of like how HSPA+ is also marketed as 4G by some companies [AT&T, stop it.]) LTE Advanced does satisfy the requirements to be called 4G. I wonder how they'll market that. Probably just LTE Advanced. Sure wish companies didn't have that much influence over what they can and can't call standards.

I'm interested in this as well, as I believe there is a difference between HSPA and 3G on the N4, plus I want to save more juice. My phone is constantly switching between HSPA/HSPA+ with WCDMA prefered selected, However my network is throttled at 3G speed just around 400kbps and I do not need the H/H+ network.

Found this on a Taiwanese forum 'mobile01', clearly showing the 3G signal indicator which I, and probably all of us don't seem to get.

[Nexus 4 General] dcd1182:
cant get your link to work but,

if i understand what youre saying (although my point isnt relevant to the op) i think what you are observing is dependent upon the network in your region.

I live in Chicago, and I see bouncing from "3g" (UMTS) / H+ all day. However when I traveled to Vegas recently I never once saw "3g". My phone only switched between H/H+

As soon as I got back to Chicago I saw 3g/H+ again, no changes on my side. btw I never see "H" in Chicago, running CM10.1

3g like my attachment right?

relevant to OP:

you wont get what you want unless someone writes an android application to interface with the LG RIL, ala dialer extensions in OEM ROMs.

There doesn't exist any app on the nexus that is comparable to what you describe from an OEM, in other words the "secret menu" you used on captivate was coded by Samsung.
