Engineering screen APN error?

Hey everyone, so I have looked everywhere for a post on this topic even at xda. So while going through my engineering menu screens I can across this notification stating my APN list needs to be fixed. Is this normal or did I actually break something at some point? Any insight would be great.

 

 

I hope the image uploaded. I'm new to using tapatalk.

Come on AJ I'm not that gullible. I may not post often but I do browse this site a lot.

 

Interesting to see it's a developer issue since I've seen this on all the rooted stock roms I have used.

The developer of the Stock ROM...

Samsung

Many people seem to forget the engineering screens aren't meant for the public. They're meant to serve a simple purpose and do that exceptionally well. Very little development time is put into these screens as they only require info requests to code and are only intended to be used by a few people. Heck, up until the Galaxy S III, one of Samsung's "apps" was called "Let's try, panning!" in the application list, that was obviously not entirely intentional for public view, but a low priority to change from development to deployment. Later software updates changed the name to more adequately reflect a public release.

 

The fact these testing apps are installed on the officially released firmware images is likely just because there isn't a justification for the "time" it would take to recompile/repackage it after removing them from the ROM image. That little bit of time adds up when you multiply it by every release candidate image x phone model x carrier configuration x etc. Also don't forget, these engineering screens are likely the same across multiple device types, software versions, and possibly even carriers and thus are not updated often on the user-end because they are low priority, it either works or it doesn't. If it doesn't work, but also is not needed, then it will stay broken until needed.

Umm..thanks for the extended answer..was not what I was actually looking to get. I am aware a lot of these screens are not for the public view. Actually a lot of what we do on here is not for public view (in terms of the average Sprint customer). I just asked if this was a normal message because every Google search I had tried failed to find any inquiries about that "error." I knew well that I actually didn't break something on the phone, it just a nuisance for me when something doesn't display property.(like how 1x is displayed as 3G...yes I know 1x is a 3G technology but in terms of data speeds, Sprint should not insist on calling it that.)

I love my DigiROM for my Note 2. It displays 1X next to signal bars when on 1xRTT, 3G when on EVDO and LTE when in LTE. It's great.

Actually, AT&T has the engineering screens removed from the official release ROMs for many of its handsets.

I've had Sprint network ticket closers ask me the PNs on the 1X and EVDO engineering screens before.

Sprint support used to ask for that info on my old EVO 4G as well.

 

As for getting the correct indicators, right now I just use signal check pro. Although, I still highly prefer not to need an app for that info. I think I'm overdue on testing out the latest release of Slimbean.

Nope. No issues. That's a note to the developer from himself to fix the screen one day. No biggie.

Hi can u help me understand how to read the LTE engineering screen on the galaxy s4 , this is from mine

Thanks just two more questions, why does it show connected with a (2) on state, and is there a way to tell if there is LTE testing in my tower, back then the screen would not show that info.

    • The Kendall/Kerr/Gillespie PCS swap is a very nice win-win for AT&T and T-Mobile. Means both of them will have a 20x20 PCS channel, though in exchange T-Mobile goes from 10x10 to 5x5 on one of their spectrum blocks. I figure AT&T will start running n2 DSS on that channel, as they have enough customers in those areas to need the capacity, while T-Mobile will probably just run B2 LTE, as once Auction 108 finally clears they'll have plenty of n41 to play with. Guessing we'll see the non-G-block 5x5 slice running n25, but it would get aggregated with n71 rather than n41 I figure as n71 will remain 20x20 there until the STA goes away (and maybe after that, as if T-Mobile gets 700 MHz as the result of VZW buying West Central Wireless's spectrum there's no reason to run LTE in 600). Which makes me think that the next move is T-Mobile trading 700A for the 5x5 of orphaned PCS (E block) to VZW once the WCW transaction closes, as that would give VZW 20x20 PCS in the area, and would give T-Mobile 700 MHz in an area where they have none. Then VZW can either trade 700B to T-Mobile as well in exchange for the AWS I block in those areas (gives T-Mobile 10x10 B12, gives VZW 15x15 B66) or they can cut a deal with AT&T to give AT&T 10x10 B12 (AT&T has the lower C block), but I'm not sure what that deal would be if trading like for like (vs. AT&T handing VZW their upper tiny slice of B5, giving VZW 15x15 to play with in that band post-WCW-acquisition). EDIT: Just looked at AWS spectrum again, and if AT&T would rather have 10x10 B12 than 2x 10x10 AWS, they could swap AWS-D for VZW's 700B block. That would give VZW 20x20 AWS, and would take AT&T down to 10x10 + 5x5...which they'd likely be fine with as they have 20x20 PCS, small cells in the busy areas, and as a result of the transaction three 10x10 chunks of spectrum in the area below 1 GHz. And if VZW traded 700A to T-Mobile for PCS-E VZW would have 20x20 PCS as well. Which is quite useful in an area that's macro-only for VZW and likely not dense enough for proper mobile usage of CBRS or C-Band (and an area where VZW doesn't even run DSS now).
    • Yeah, $250 credit for an S22 is awful. tbf last year they didn't have solid upgrade credits until mid-late April, which is when I paid $225 to swap my S21 for an S22. Happy to wait 'til then for that kind of deal, though I'll be annoyed at battery life in the mean time.
    • Miserable upgrade credits from Samsung this year unless you want to rely on carrier financing. Sticking with S22U for a while. 
    • So far we've documented close to 100 Sprint conversions in NYC with permits still rolling in and that's only what we've identified manually. Tons of sites get converted/updated without permits so there's potentially a lot more that we haven't spotted yet. There are also dozens of sites that are still broadcasting the keep PLMN, some have been decommissioned but historically the vast majority have been converted.
