The signal strength bars that you see on the notification banner mean close to nothing. Example: a few years ago iPhone 4 had an antenna/signal problem. Signal bars went down to one or two bars every time you touched the metal exterior of the phone. People went crazy upset about it and apple released a "fix". All it did was to artificially increase the number of bars from one or two to three or four on the display with no actual change in the received signal. The real fix was to use a cover for the phone to avoid contact with the metal part, which apple quietly agreed to provide for free to whoever requested it. So don't be fooled by the bars.

The true measure of how good the radio performs is in three things: first of all the actual signal strength in dBm which you can either find in settings, about phone, status, sim status, or you can use an app to monitor it. Note that even this number is subject to changes that are beyond the control of your phone because the strength of the phone company signal can change from hour to hour and from one side of your house to the other. So you need to monitor this number and average it out over a few days to get a good estimate.

The second factor is the quality of the connection; how stable it is and whether it keeps dropping and reconnecting. One way to guage it is to observe the voice quality when voice over LTE is enabled, since it requires a continuous and steady connection. It can also be partially evaluated using a data speed test.

And finally, how the kernel works with the radio determines the battery consumption when the phone is sitting there ostensibly idle. If the phone wakes up too often to check the data connection and reestablish it when it's not really needed then the battery will drain too much and you will get a poor standby performance. You can use an app like better battery stats to check the wakelocks on your phone and in particular the kernel msm_hsic_host wakelock which is responsible for data connection to make sure it does not keep the phone awake to much. It should only account for a few percentage points of the awake time.

I hope this helps.
[Nexus 6  General] Formhault:
But... when the bars get stuck, so does the dBm indicator from Settings - About... :eek:

I don't think I have voice over LTE. Nor do I have a toggle for this.

But... all of the modems I've tried so far are stable. As in... no dropped calls & anything like that. The only problem is that some modems (basically every one of them, except for 95R) have the signal indicator getting stuck issue...

So... I enable mobile data when I go to sleep?

[Nexus 6  General] reaper000:
If on a Marshmallow ROM, a Marshmallow bootloader is highly recommended.

A Marshmallow radio is also suggested, though you likely can use whatever Lollipop radio you want.

Marshmallow unified the radios across carriers. To the best of my knowledge, there is no carrier-specific (ATT or VZW, etc) Marshmallow radios.
[Nexus 6  General] Formhault:
M radios suck for me. They're so bad the signal indicator (status bar AND dBm thing in Settings - About) get stuck. Some times, just the indicator is stuck, but signal is good... Other times, if the indicator gets stuck on low, and I go to a high signal area... there's a chance the signal quality would MATCH that of the indicator, although it's a bad reading. When that happens, it sucks :)

So far, 95R has proven to be the best, which is a LP radio. And I have been changing radios (about 5) these past few weeks, with little to no change in battery life, so I'll stick to 95R...
[Nexus 6  General] dxintel:
Signal (dBm) hangs or freezes

I have been having the exact same problem since I have been running Marshmallow. It was very difficult to determine if I actually had signal or not (as I live in a rural area where signal is normally week) So I would be in locations where it was reporting -89dBm but actually not have any service, or at other times it would be reporting -113dBm and I would be using the internet. So strange that the signal status in the phone itself (About Phone -> Status -> SIM status) would hang and report incorrectly, the dBm status in *#*#4636#*#* was also incorrect. I have been able to verify this on 3 different Nexus 6 devises running 6.0 and 6.0.1 and with different cell carriers.

I remember not having this issue in a version on 5.1.X so I took your advice and loaded radio 95R (5.1.0-lmy47i) and so far its been reporting status perfectly. I will also keep a eye on battery life etc and report back if I find any negative effects.

I am glad I found your post, thanks again. I have been trying to narrow this issue down for over 2 months, can't believe Google has not corrected this. I guess if you live in an location where you continually have signal 100% of the time you would never notice as data and voice would always be working.
[Nexus 6  General] Formhault:
Well, I'm glad you're having the same problem. Lol :silly: . I mean I'm glad that this way I know I'm not the only one.

[MENTION=5964313]wrongway213[/MENTION] has also had similar experiences with the latest (32R) modem.

Yep, 95R has proven to be the best when it comes to signal indication. Not sure how good it is compared to all the other modems in terms of battery life, as I couldn't stick on one specific modem for more than 2 days (the indicator, man, crap), so I don't think I could gather enough useful data. But in that time, as I previously said, the battery life seemed to be pretty much the same. My SoT didn't get 1 hour longer, so...

But sure, do let me know about your findings!

Yep. Google isn't as caring as it once was. Or so it seems...

Hi all,

I'm running baseband MDM9625_104662.22.05.32R on 6.0.1 stock; and for some reason it does not perform as good as previous versions.

Hello would you mind making a few flashable zips for the Nexus 6p. I am no dev but have been here on XDA and know a lil bit but I do not know how to turn a radio.IMG into a recovery flashable zip. If not thanks anyhow just for reading this. I still have Nexus 6 also and very much appreciate your contribution.
[Nexus 6  General] robertm2011:
The .IMG file is flashable on the latest version of TWRP or you can use Flashify.

Are you sure a radio. IMG is flashable in TWRP

Absolutely.

Did you notice that I was asking about the Nexus 6p? I know it's possible with Nexus 6
[Nexus 6  General] robertm2011:
Yes, just tap install, then tap image file; I would think that TWRP has the same options across the board, but, hey, do as you like.
[Nexus 6  General] treIII:
I just attempted this and I found the problem. Twrp when installing an .IMG file asks where to install it and gives 4 options being boot, recovery, system or data. I do not know where to install the radio.IMG or if it is possible. I have twrp 3.0 installed.
[Nexus 6  General] robertm2011:
Hmm, you could use Flashify from the Play Store, that's what I've used to keep up with radio releases, it should work on the 6P, good luck.
[Nexus 6  General] treIII:
I wish. Won't work
[Nexus 6  General] RandomPooka:
Doesn't fastboot allow the direct flashing of radio images with something like this?

fastboot flash radio radioname.img

-- Edit --

You could do a TWRP backup including your EFS partition to test it. If it fails, you'll have the backup, provided TWRP does back up that partition on the 6P. I don't have one and haven't seen the recovery for it to know if they behave this way in recovery or fastboot.

If you enter the fastboot command with no arguments, it should give you a short list of what arguments you can use, just like most command line apps do.

fastboot -help

fastboot /help

fastboot /?

I'm still on 01R. If you could tell me how to pull a radio, I would upload it. I want to try 04R, but I can wait. I'm a noob, can I pull it using Wugs? If so, how?
[Nexus 6  General] efrant:
In a terminal emulator or in an ADB shell type:

su
dd if=/dev/block/platform/msm_sdcc.1/by-name/modem of=/sdcard/modem.img

That should save your radio as a file called modem.img in /sdcard. Root required of course.
[Nexus 6  General] churche0:
Awesome, thanks. Did that. Came about to about 112MB. Where would be best to upload it for you guys?
[Nexus 6  General] zephiK:
Anywhere would be fine, mediafire is a good choice.
[Nexus 6  General] efrant:
If you zip it up, it should reduce the size significantly.
[Nexus 6  General] churche0:
Thanks. I just uploaded the .img file. Here is the link:

https://www.mediafire.com/?zytbbutrxf7f9re

I hope I did it right, any way for you guys to quickly verify this is what you need?
[Nexus 6  General] simms22:
thats an awefully large file, twice as large as both in the op of the thread.
[Nexus 6  General] churche0:
I noticed that, it's why I specified that. However, I just downloaded a terminal emulator app, typed in that code and copied the file to my PC and uploaded it. Beyond that, I've no idea.
[Nexus 6  General] efrant:
It's large because you used the dd command. dd pulls every byte from the modem partition, and if they are blank, it pads the output file with zeros. If you take a hex editor and remove all the trailing zeros, it will be the same size as the radios that come with the factory image.

In the past, being able to flash a dumped radio using fastboot depended on the device. On the Galaxy Nexus, the trailing zeros needed to be trimmed before fastboot would let you flash it. On the Nexus 4 and 5, you didn't have trim the file. Of course, it was always flashable using dd, as dd doesn't care what you tell it to write, nor to where.
[Nexus 6  General] churche0:
Well, you clearly know what you're talking about so I'll default to that answer. As long as it's what you guys need, it's all good. Would I also just be able to use fastboot to flash this back if I wanted?
[Nexus 6  General] efrant:
Not sure. When I have a chance and am in front of a computer, I'll try it out and post here. I'll try it as is and trimmed. (Unless someone gets to it first.)
[Nexus 6  General] churche0:
Cool, I'll look out for your findings. Thanks for your help, I appreciate it.
[Nexus 6  General] efrant:
So I had a chance to start testing this.

It seems like fastboot allows you to flash it as is without trimming (as was the case with the N4 and N5). See below:

C:\Users\Admin\Desktop>fastboot flash radio modem.img
target reported max download size of 536870912 bytes
sending 'radio' (114688 KB)...
OKAY [ 4.980s]
writing 'radio'...
OKAY [ 0.001s]
finished. total time: 4.983s

It boots fine. I then rebooted back into the bootloader, but it still showed that I was on the 0.4 radio.

I then tried flashing the 0.4 radio from the factory image. See below:

C:\Users\Admin\Desktop>fastboot flash radio radio-shamu-d4.0-9625-02.55.04.img
target reported max download size of 536870912 bytes

(bootloader) flashing mdm1m9kefs3 ...
(bootloader) flashing versions ...
OKAY [ 3.550s]
finished. total time: 6.978s

So, it seems like the radio images in the factory image also contain something that needs to be written to mdm1m9kefs1, mdm1m9kefs2, mdm1m9kefs3 and versions.

This needs more looking into. Will get to it when time permits.
[Nexus 6  General] churche0:
So it flashes, but doesn't contain some other stuff that needs to be written? Sorry, I'm totally clueless on this stuff. Regardless, I'm interested to see what you find.
[Nexus 6  General] mrphil101:
Is good to have efrant looking. He's been very helpful with many other devices. Been around long enough to b considered an ol' timer!
[Nexus 6  General] christianpeso:
Yes, even the new version of TWRP does not flash radio images. If someone made the radio into a flash able zip, then TWRP would work. Since it is a .img radio file, you can only fastboot it.

[Nexus 6  General] christianpeso:
When you installed the radio, did you check to see if you had "Enhanced 4g LTE Mode" enabled under Settings>Mobile?
[Nexus 6  General] wtherrell:
I did. There was no enable button. I then went into the Phone info service app and pressed the "turn on Volte provisioning flag" then turned radio off, then on again. This worked in past radio versions, but still no "Enhanced 4g LTE mode" in settings. Going back to 32r, everything worked fine.

One other thing, I used the .zip 34r recovery flashable file not the .IMG fastboot method.
[Nexus 6  General] Alxoom33:

Try rebooting after changing your settings. If that doesn't have try flashing the Radio image file. You can use fastboot, NRT, Flashfire, or perhaps Flashify.
