knopper If T-Mobile has a version and Cricket has a version, wouldn't that mean the TracFone one works with those towers?

      Biden2020prez no not necessarily. For one they are different model numbers so the 2 carriers are not selling the same phone. Secondly, the LTE bands are different between the models. You need certain LTE bands such as band 71 to work well on T-Mobile. This band is not on the Tracfone model. Tracfone’s since shifted their focus to providing service that strictly connects to the Verizon network so the addition of band 71 is not a necessity on their phone. Hope this clear things up

          knopper Yes, that clears things up. So if I get this phone unlocked, I can't use it on T-Mobile?

          Pretty smart to have a decent unlock policy, but make customers forced to your network even after the phone is unlocked...

              You probably can use it on t-mobile, but it just won't work as well, due to the missing bands

              Biden2020prez My bad, I just looked into it again. The Tracfone version (model T408DL) actually has band 71, so is all set for T-Mobile. I had it the other way around....the T-Mobile version (model 4058W) does not have band 13, which is very important for Verizon (it's Verizon's low band that allows for better indoor coverage and better rural area coverage). So actually, the T-Mobile version would not be good to try to use unlocked on the Verizon network. However using the Tracfone version on T-Mobile would be fine in your and Reifam 's cases.

                  How can you see what bands are on the phone? Also, is there a list of what carriers use what bands?

                      knopper Is the T-Mobile one and Tracfone one, the same software?

                          Reifam Technically no, the Tracfone one has a Tracfone bootup screen, so there are going to be some customizations. However both are Android 11 and probably have a lot of similarities in the tools, apps and settings. I don't own the T-Mobile version though to really be able to confirm.

                            lgexalter1 HAHA, I don't even know what that means. TCL doesn't use com.tcl very often. All the com.android apps were signed differently per phone. TCL uses package name of one or two apps com.tcl, one of those is camera. So I took the camera app from a TCL smartphone to see if it would install (not b/c I thought it would be a better camera app), and it didn't have the signatures issue, but it had the NO_MATCHING_ABIS issue.

                                Biden2020prez Right, that would make sense because it's signed by tcl (or tcl approved) but it's likely that the smartphone is running a different architecture (different phones have different architectures, some are armeabi-v7a Arm86-v8a x86 etc. It's basically the type of processor, there are different versions of every app for different processors, if it's the wrong one it may not install or may crash)

                                      lgexalter1 If I could install the settings APK from another phone (like LG can), it's exciting because I can try to allow APK installation. But there is no real maila of installing the camera APK, it was just an experiment.

                                              Biden2020prez If you open files with
                                              am start com.android.documentsui/com.android.documentsui.ViewDownloadsActivity
                                              and you select on an apk it opens the installer and asks if you want to install from unknown sources and gives you the option to click continue, which than proceeds to try to install the app, it ends off with message 'App not installed'. So I dont know what you would gain by putting on a different settings app.

                                              lgexalter1 [Login to see the link] is the system/framework folder

                                                    It was a tracfone one. The issue is that the property is not set, meaning if it would be set to true then package installation would be allowed.

                                                    darth I can disable apps: adb shell pm disable-user --user 0 org.chromium.chrome
                                                    Disables the browser.

                                                    lgexalter1 How do I figure out the architecture?

                                                    darth True, in general a smartphone settings app would be nice to have because it'll include more capabilities.
