I have been visiting S4GRU for quite some time, and one of the most common issues I see popping up is confusion from users--especially when they first get 4G LTE devices and/or LTE service--regarding their signal strengths. For some reason, the signal bars on many devices do not display what most users expect them to display. It seems strange that we have to enter special dialer codes just to see what our LTE signal is!
With that in mind, I started creating an Android app from scratch. I had never created an app before, so it took a few months before it was ready for the public, but its time has come. Robert and a few others have been beta testing it for me since October, and I recently released it onto Google Play. Robert gave me the go-ahead to give it a mention here on S4GRU, so here goes..
It's called SignalCheck, and it is available on Google Play here: https://play.google.com/store/apps/developer?id=Blue+Line+Computing
The "Lite" version is free; the "Pro" version has a small one-time fee but includes a bunch of extras, including signal bars in the notification area, a widget, the ability to alert a user when they pick up an LTE or 800 SMR signal, one-button instant connection reset, the street address of the connected 1X site, and menu shortcuts to some screens that are usually only accessible with dialer codes. I intend to offer S4GRU Premier Sponsors special benefits in the near future, as soon as I figure out a feasible way to do that.
This is the first app I have ever developed, so I'd appreciate any and all feedback, both positive and negative. I have been trying to educate myself as much as possible regarding cellular technologies, as I didn't know much before I started this project. My goal is to make this app as accurate and useful as possible for all the "nerds" on here.. myself included!
I intend to continue squashing bugs as they are reported, and adding features as they are requested. As I learn more about Android programming and cellular technology, I'll improve things. Please let me know what you would like to see, and I'll do what I can.
My "Beta Crew" helps test out the app before public updates are pushed out. Membership is by invite only but anyone is welcome to join in our discussions or get a sneak peek at what is going on (see thread here).

Here are some screen shots from a previous version.. there have been tweaks since this release, but this is basically what you get:
With the FCC and Sprint, T-Mobile, AT&T and Verizon have agreed to this new unlocking policy. How does this effect sprint phones such as the IPhone. I have heard that Sprint can unlock your phone but you can not take it to other carriers such as Verizon and the IPhone can only be used overseas. (Correct me if I am wrong). I am glad that this has finally happened. But when it comes to Sprint how would this work?
I moved to TMobile two weeks ago. Service has been exemplary at my home. Cell one block away -95db signal usually 3 to 4 iPhone bars. Today I noticed the signal was much weaker. -110db 2 iPhone bars. I don’t see any crews at the cell site so I’m wondering if this is a temporary outage or did the cell get shut down. Is there any way to determine this? What’s weird also the cell I’m connecting to now is a mile away (versus a city block) and my Apple Watch still gets two dots signal strength. Does this sound reasonable for a 30 foot cell that far away which is LTE band 2 and 66 capable. With the exception of the watch I’ve been using cellmapper.net to determine the cells I’m using based on PCI numbers.
That is a nice perk. Btw you can just use anyone's T-mobile number to get it. Nothing ever gets sent to the number. I have a few friends with T-Mobile so I just pick one of their numbers when I need to use it. I'm pretty sure it only works for like an hour or so though? Or at least I remember there being some sort of time limit the last time I used it (or possibly I had two flights and it only works on one flight a day?) Sent from my Pixel 4 XL using Tapatalk
