SignalCheck - Android app to monitor your Wi-Fi/2G/3G/4G LTE/5G-NR signal strengths

[davidtm]

Aww, now I won't enjoy the change in my readout from nTelos to Sprint. ????

 

Thanks, Mike, for an awesome app! ????

I wouldn't mind throwing some of my expertise towards the app. I have worked with Android for several years now.

There is no major bugs so I don't think Mikejeep needs to comment to much if mikejeep is busy.

 

List of bugs I have seen mentioned.

 

WCDMA not being displayed on TMobile S7. Not sure the problem.

 

Notes need to match the exact sector first before looking for a matching the site GCI.

 

Samsung 03 not showing B25 2nd carrier.

If(0x76 <market GCI && market GCI < 0xB9) // it is samsung market.

 

Possible 3rd carrier ALU 41,42,43 this needs confirmed correct first. Only one site in New Haven Connecticut so far.

 

Clear conversion nokia is B25 market GCI and 3x sector.

Any new feature requests? I haven't followed the thread enough.

 

The issue i ran into with the system short cuts would be a nice enhancement maybe with some device detection or a model selection.

Just to let everyone know, I talked to Mike and he definitely has not abandoned the app. He's just been busy (in a good way!) and hasn't really had time to update it or get on s4gru. He said he'll try to find some time to catch up on everything in the next few days.

New Orleans looks like it launched third carrier with 41,42, and 43. http://s4gru.com/index.php?/topic/7559-4x4-mimo-phones-sprint-lte/?p=492454 Many many sites with the 41,42, and 43.

Signal check is not show which bands anymore. Showing just 1xRTT LTE. WHY I'D THAT

Mike,

 

I just upgraded to Nougat and looking at the diagnostics, it looks like the phone is now providing the EARFCN via the API.  As soon as you get that going, I'll have it made!

Did anyone ever figure out the dev/smd code for the Nexus 6 to show the EARFCN/Frequency data?  It pains me that I cannot use this on the N6 in Cellmapper nor SignalCheck.

Is the N6 using Android 7? If so, cell mapper uses the new API and doesn't need root anymore to get the earfcn. Signal Check hasn't been updated yet for that.

Ahh. If you enable full logging for SuperSU for CellMapper (while it's closed), then run CellMapper for a minute and exit, then go to SuperSU, it should have logs. Look for the lines saying "cat /dev/______". Whatever that _____ is is the appropriate device name to give SCP.

Doesn't work that way unfortunately on my N6 with Nougat.

Because of Nougat you can disable the option to use root and it'll work (I'm guessing it doesn't show the earfcn for you if you have root mode enabled?). If CellMapper shows the earfcn with root on Marshmallow, then whatever device it's using must be working.

Oooh, a reason to upgrade to 7! (I refuse to use the stupid names).

I just went ahead and installed the PureNexus Android 7 ROM that works with Project Fi. Doesn't help SCP, but now Cellmapper shows EARFCN and band. Thanks.

LTE Discovery also uses the new API and can get earfcn data on 7.

Huh.  If I used the Nexus 5 version of Pure Nexus, do you think the API would work?

If it's based on Android 7, there's a good possibility. The API specifies it can return a value for the earfcn though that basically means "I don't know". Try it and see (after making a TWRP backup! I prefer to use a USB OTG cable with a flash drive or SD card for this)

If time permits, I intend to try it this evening.  I'll back up my Nexus 5 and see if I can update it to Nougat and get out EARFCN from the API.

By the way, I think that mikejeep may be done with SignalCheck Pro.  It has not been updated in six months.  And he no longer maintains a presence in this thread.

 

Hello strangers!!! SURPRISE! I'm not done..

 

I am *way* behind on my e-mail and S4GRU threads, and have not had much time to work on the app over the past several months. But I'm lurking. And have been (slowly) working on an update to include the new API features. As I've privately told a few of you, I'm just crazy busy with other things in life and at work. Everything is great, just not enough time in the day.

 

Looking forward to being as active as I used to be. Sincere apologies for giving anyone the impression that the app was dead and I appreciate your patience. SignalCheck had hit a point of stability where I felt like I could let it simmer for a bit without a huge impact to users. Not because I don't enjoy working on it, just because I was burning the candle at both ends and real life takes priority sometimes. Maintaining the app could probably be a (terrible-paying) full-time job but it's still a fun hobby to me.

 

I'm slowly but surely working through all the e-mails and posts. It's all good!

It was a bad idea.  After the update, I lost LTE and once I got it back, I now do not get PCI, TAC, SNR, or most other information aside from GCI and RSRP.  I think I'll be rolling back.

 

EDIT: Rolled back successfully.  Apparently the N5 never reported the SNR to begin with.  In any case, it now correctly shows PCI and TAC again.

My 6P never displayed the SNR correctly. It was never less than 20, but would sometimes go above that. The Pixel doesn't show SNR at all. Losing the other info though is a deal breaker, especially for logging purposes.
