[Nexus 5 Q&A, Help & Troubleshooting] markdapimp:
I'm sitting at home nice good HSPA+ Signal then all of a sudden it just drops the EDGE

my other phone (iPhone is still on HSPA+ no issues) great so I toggle airplane mode on and off boom still edge, so I reboot and boom STILL EDGE

After a while it reconnect to HSPA+ or until it picks up LTE

Does this happen to you? It seems the radio got even crappier with 4.4.2

Im fully stock 100% I have 2 Nexus 5 units in hand one is from T-Mobile one is from play store both experience the same problem

Does anyone know if this is software or hardware Antenna or qFE1100 and does this happen to you?

Why would i flash back to 4.4. The Point is google ffffed up somewhere and I hope this gains momentum as right now Google does not see it as an issue and is blaming it on the carrier.
[Nexus 5 Q&A, Help & Troubleshooting] GuestK00442:
I think I'm having the same issue, my data has been bad(between .5mbps-1mbps) since I got this phone. First I thought it was the APN settings, then I thought maybe the towers, right now I'm thinking I might be throttled by at&t. I call them one person says yes, call again another person says no, wtf!

I came from a galaxy s 3 with no build problems, just slow updates. Damn I guess there's no winning with Android.
[Nexus 5 Q&A, Help & Troubleshooting] gee2012:
No i think you misunderstood me, i meant flashing only a different radio.modem and not an older rom.
[Nexus 5 Q&A, Help & Troubleshooting] wideasleep1:
Not the point at all. Either you want a solution or you want to blame. This isn't an issue for the 3 N5's I administer so it sounds like a localised problem.
[Nexus 5 Q&A, Help & Troubleshooting] markdapimp:
Take your Nexus 5's to an area where you don't get HSPA+ for example your basement then take it out and bring it to an area with HSPA+

Let it sit and see if it will switch to HSPA+ if not toggle airplane mode on then off then see if it will switch.
[Nexus 5 Q&A, Help & Troubleshooting] wideasleep1:
If you physically degrade the signal (basement) there will be delays even after returning to strong signal (recovery). Some of it is radio firmware code, some of it is signal strength (physical, cusp of frequencies) and some of it is data polling stalls. You and all of us are waiting on VoLTE phones, which should alleviate these handovers.
[Nexus 5 Q&A, Help & Troubleshooting] danarama:
Yes it does. Works great. Switches multiple times on my journey to and from work.

You blame it on the update. That's why I suggested flashing an old radio. If it ceases then there's your proof.

[Nexus 5 Q&A, Help & Troubleshooting] danarama:
Have the asu and db been checked when it switches to edge? Maybe the hspa+ is weaker signal and nexus switches to stronger connection at different thresholds to other phones.

Its arguably better to have strong edge than weak hspa+
[Nexus 5 Q&A, Help & Troubleshooting] markdapimp:
I can call but no data and or mms
[Nexus 5 Q&A, Help & Troubleshooting] markdapimp:
Id say the edge is stronger
[Nexus 5 Q&A, Help & Troubleshooting] marleyfan61:
My signal is actually stronger than my previous phone so I'm quite happy with the radio. My HTC Amaze would lose signal constantly in my house. I would have to walk around the house to try and find a place with signal. The N5 has never dropped below 2 bars anywhere in the house.
[Nexus 5 Q&A, Help & Troubleshooting] danarama:
Its going to be impossible to compare as my network doesn't have anything below 3g but it might be interesting to monitor signal strength in about phone > settings. Although to pre-empt it would be hard. Wonder if theres an app to monitor it? See what strength hspa+ is when it switches out....

[Nexus 5 Q&A, Help & Troubleshooting] WoodburyMan:
Try a different ROM. For some reason OmniRom used to give me random signal drops even to where it would say "No Signal" and such then would connect only to 3G/2G when I know i was in a LTE area. And other odd behaviors. Threw on SlimROM and it works fine. (CyanogenMod would work fine too).

[Nexus 5 Q&A, Help & Troubleshooting] markdapimp:
Dont talk trash about any other product, you know the Nexus 5 has problems and you know it.

and calls on EDGE sound terrible and 4G speed is very fast better than EDGE
[Nexus 5 Q&A, Help & Troubleshooting] wideasleep1:
His point is you're using improper data points, AND making a comparison on them. All your vid indicates to me is that your Nexus 5's are behaving consistently between themselves, and you seem pleased the Apple 'indicator' APPEARS more responsive to signal recovery, in that specific location. You do realise you're comparing different hardware and software code, and will get variations in results. Perhaps the iPhone is your solution?
[Nexus 5 Q&A, Help & Troubleshooting] markdapimp:
Another video coming up with extremely strong signal. Nexus 5 rebooting selecting 3g and airplane mode all of that and its still on Edge

Only till i walk outside and it picks up LTE is when it starts moving out of edge.
[Nexus 5 Q&A, Help & Troubleshooting] monkeypaws:
Since when do you need data to make calls. Data and service for calls are two different things. I could have no data but still make calls just fine. I just bought my n5 from T-Mobile yesterday and have not seen edge service. Only LTE with fast speeds.

You can use the "fastboot flash radio radio.img" command which I believe is documented in the long method of the return to stock threadvin general

You'd need to extract an .img from a flashable zip of the radio which there is also a thread in general. Hang on, i'll dig out the latter while you have a look at that return to stock thread

Different radios work differently for different people. Its always been the case on android. Doesn't mean there is something for Google to fix though.... The latest and greatest isn't always so. As a root user, I have always had to find the best radio for me. Nexus is no exception.

I.am surprised however, there isn't an official way to change / update radios for theb"common" user. With so much regional variation (and many, many other variables that affect signal) its kind of stupid to force radio updates in everyone

I don't mean to be rude, but if you had expectations that were already being met with iOS, why go to Android?

Again, I would try getting an RMA, then seeing if the problem persists. If it does, wait the 6 months out, and get another phone that suits your needs better. (I remember you saint you had JUMP, that's why I said 6 months.)

[Nexus 5 Q&A, Help & Troubleshooting] godleye:
I Went through and flashed all modems and checked the signal strength from each. .15 (KRT01B) is what worked best for me.
[Nexus 5 Q&A, Help & Troubleshooting] danarama:
Yes of course. But what works best for you won't work best for everyone and herein lies the problem.

There are hundreds, thousands, millions of environmental variables that makes radio's act differently. You could be 10 miles from your mast, and I could be 10 miles away from the same mast, but there's more dust in the air where I live and more tin roofs between you and the mast... Meaning we both get completely different results. What works best in your specific set of circumstances may not be for me.

So what Android OEMs tend to do (and I'm not sure if iOS or other devices do this) is release a new radio with a new firmware. But this "upgrade" isn't always so. It fixes my dust particles issue but is worse for me. Thats why there should be a more manual approach perhaps, so people can easily change.

With Carrier branded devices, the carrier will create radios that work best on their network, with their masts etc This is perhaps one downfall with the nexus and lack of carrier branding.

[Nexus 5 Q&A, Help & Troubleshooting] wideasleep1:
Once again, all you've shown is the iPhone recovers differently than the Nexi. The Nexi obviously doesn't behave to your perceived preference: fastest signal first. Nexi appears (regardless of radio version) to recover to the strongest signal, THEN attempt to negotiate to the faster bands. Of course (and again) in your selected location and signal strength, the Nexi prefers the EDGE, and the iPhone prefers the HSPA upon recovery from signal loss. Since the vid shows Nexi with strong HSPA when you start, we can assume it does indeed fully recover to the strongest and fastest band given time.
[Nexus 5 Q&A, Help & Troubleshooting] markdapimp:
yup after 40 mins... Thats way too long though, You have a Nexus 5 try it and see how long it will take to recover

new radio is pretty bad

The new radio is out and while it gives us sprint users better access to b41 it reminds me a lot of the .23 radio.. its pretty bad. In strong signal areas it performs about as well as the .15 radio but anything less than strong signal it is really really slow. not to mention like the .23 radio the 3g to lte handoff is awful.. and also i still find my self having to airplane mode it once in a while because it wont connect to lte or 3g.. particularly when i go from 3g to lte.

I love my nexus but i guess this is one of the few downsides to owning a non carrier based phone.. you look at the htc one m8 on sprint and the transitions between bands and between lte and 3g are perfect.. coverage is great and speeds are fantastic.

I am pretty disappointed since we had to wait 6 months to get this radio,.. ive gone back to the .15 radio and ill settle with not picking up the b41 as easily.

who knows maybe the next version of android that will be revealed at I/O will have a new radio.. but something tells me the nexus 5 will never have a perfect radio
