Help What time period is represented on OpenSignal maps?

svim
OpenSignal is primarily a speed test utility that includes the maps with carrier status info. But you're making a big mistake fixating solely on the map, just use the app for its primary function. Tap on that big Speed Test button and the app will use the cellular radio chip in your phone to check and analyze your phone's connectivity with your carrier's closest cell tower/access point. If there's no 3G connectivity in the resulting scan you just performed, you'll see that within seconds, and eventually that's going to be registered in the accumulated data being shown in the crowd-sourced map data.
OpenSignal depends on data it collects from app users. All the stats the app displays are based on that on-going, crowd-sourced info, not the packaged, market-based data that the carriers might provide. (Note that there is a fundamental weakness to this strategy -- in a densely populated area there will be more data from more users but in more sparsely populated area there will be very little to no users. So the map showing carrier data and local cell tower/access points can be quite useful in a larger city setting, but not so much in a more remote region.)

Internal Storage maxing out.

Hadron
Cache is always safe to delete.

It usually is safe to delete data on an SMS app because messages are stored by another app. But as I say I don't know about RCS Chat, which this app can also do. But if this app is wasting space keeping its own copy of SMS/MMS then presumably if you cleared its data it would just copy them all back, so it would probably be a waste of effort.

So my guess is that the fact that SMS/MMS messages are stored by a separate system app is irrelevant, and to reduce space here you will need to delete some messages. Hence trying to find a backup tool that will let you view messages on another device sounds like what's needed.

I'd be curious about whether a different SMS app would be more efficient with space or do the same thing (as always with the caveat that most don't support RCS Chat, so if you do use that Google's Messages app may be the only alternative). But if another app did the same thing you would run out of space! I can't tell for myself because my own 11,000 SMS plus maybe 20 MMS (I know nobody who uses MMS) only use a few MB.

HI I'm having a similar problem maybe someone can help me with when I go to turn it on the mini android guy come on then a bit of info in the lower right corner (Android OS 4.0, Kernel 3.0.8, Build # V1.5.1, then after a few seconds the info goes away & the droid stays, until I hold the power button to turn it off, & it appears as if the antennas on the droid are slightly brighter on the ( right side as it's looking at you, but it's actually it's left side if it were standing in front of you) theirs no noise or vibrations as it coming on. Does anyone have any helpful suggestive advice on what to do?? Thanks...

Best App for Organization

A lot of information on the Internet and have to filter a lot to find exactly what you need. And there are millions of people working on applications to please everyone. It's all about money. I chose Bank Logs for myself and read different information. I am very close to different hacker activities and I think there should be such kind of applications. They can simplify your life a lot. And I advise you to learn some new information every day.

Samsung J2 pro will not update software?

Hadron
It's certainly possible that a low-end device might not have received any updates. All phones stop getting updates at some point, and budget devices stop getting them sooner. Samsung have recently become quite good with updates for their higher-end devices and even mid-rangers, but it's possible that a 2018 budget device that was only released in some regions might have been neglected.

But to check, I looked on Sammobile.com to see whether such an update existed. They list 2 SM-J250G variants for Australia, which they call OPP and XSA (neither of those obviously says "Telstra" to me). Both are showing 7.1.1 as the most recent firmware version. In fact, contrary to what GSMArena says, I haven't found any SM-J250 variant in any country where anything higher than 7.1.1 is available (the search interface doesn't let me look at a list of all variants in all countries, so I've just tried half a dozen or so, but it's the same story with all of them). So to be honest it's not looking good, especially since Android 8 came out in 2017 (so before the J2 Pro was released, though again it's not uncommon for lower-end devices to be released with older OS versions) - if they have not released an update by now it doesn't seem very likely (though my old Note 10.1 tablet did receive a surprise OS update after a 2 year gap - Sammy can be capricious about these things!).
