Unlocked Phone only works on Vodafone

R
Thank you for your detailed response Hadron. I did try a SIM from O2, and has the same problem. I also tried a SIM from Lebara, which uses the EE network, but their SIM could not even register on the network.

All the phone repair shops that I visited were completely baffled by this problem. The fact that my GiffGaff SIM worked in another phone leads me to believe that my S8 is slowly "dying". I went ahead and purchased a Pixel 6a, primarily because it had good reviews and I wanted a small screen size.

Uris from the filepicker

D
Hi all, Newbie here. I am working on an app that involves picking a mp3 file , saving its Uri to a database, and then later selecting the file from the database and playing it with the mediaPlayer. This is all similar to creating a playlist from the music stored on the device. In this regard I have several questions.

I can only get the mediaPlayer to play the mp3 if the Uri is an audio based Uri. The filePicker seems to want to return a document based Uri. So, Is there a way to get the mediaPlayer to play the file based on the content/document based Uri?

Is there a simple way to convert the document Uri into an audio based Uri?

Is there a way to get the filePicker to return an audio based Uri?

Would all this be easier if I used the exoPlayer instead of the builtin mediaPlayer?

Thanks for any advice and/or code samples.

Help Two Android phones got slower at the same time

nickdalzell
I went with a Z Flip 4. I have been spoiled by Samsung since the SIII, and the Flip is more my speed with its unique design that can still fit a pocket properly yet still turn into a huge 6.7" smartphone if needed, and if not, the cover screen allows it to function like a dumbphone if you want, and there's a satisfaction one gets by hanging up on a telemarketer by slapping it shut.

"Content is not allowed in prolog error" despite valid XML

Did you solve?

Yes, yesterday. It turns out that Android hates having empty directories, and since I had deleted all the navigation components that use Fragments and XML and switched to Compose navigation, I had an empty "menu" directory and an empty "navigation" directory. I hadn't deleted them in case I wanted to backtrack! But as soon as I deleted the empty directories, the error went. It was nothing to do with a prolog in my XML at all. Total red herring of an error message.

Goodbye, Wi-Fi

Hadron
The higher frequency of visible light vs radio is source of both the advantage (bandwidth) and the disadvantage (signal blocking) here, but the latter is just a feature of the particular frequency range: increase the frequency further and it starts to penetrate clothing and thin walls again, and in principle you can also get higher bandwidth. So maybe we should skip over "LiFi" and move direct to "XiFi": X-ray based wireless communications? Solve both of those problems and as a bonus the people who are paranoid about radiation from wireless networks would finally have the satisfaction of being justified? ;)

Play Store scam?

A
nickdalzell said:
The only thing that I've had happen with prepaid cards (especially those infamous 'vanilla' cards you get at dollar stores) is a straight up decline--many don't work online just in stores. I think many online stores require a name tied to the card or a billing address, even on a prepaid or bank debit card, so it limits such options. But I've never had an account suspension over it. It just never completes the transaction either claiming it's declined, unsuccessful, or not supported.
Click to expand...
That was my previous experience. This time the card may not have been "registered" for on-line use in the latest format. It used to require only a zip code to be accepted for on-line purchases, and before that nothing at all, but now registration requires a name and some address beyond a zip code. Refusing the transaction I can understand but demanding bank statements, as the play store and the e-mail in the gmail account attached to the play store ID did, seems more than a little over the top.

Do Knock-Off Phones Deserve their Unsavory Reputation?

nickdalzell
There are actual fake Samsung phones that to the untrained, look pretty close enough to fool anyone. They can even cop One UI and apps and then they go deeper and fake specs by editing files such as build.prop and others to make the phone's 'about phone' section lie about the RAM, storage, and CPU cores. Some even have fake cameras posing as a multi-camera system with the only real camera being very low quality like 5 MP or less. Some even fake the Android version and easter egg. There are a ton out there that look like they're running Android 12 or 13 but they're just heavily-themed versions of Android 6 or 8. Some aren't even LTE capable, relying on outdated 3G and 2G. Some go farther and use stolen IMEI numbers.

Horribly Hacked

Hadron
When you say "program" I assume that this is speculation and you don't know what program you are talking about? Please correct me if that is wrong.

One thing you need to understand is that different smart devices run on different hardware platforms and different operating systems. So one program being able to infect them all is really, really unlikely. More likely is that the problem is that you are using one or more accounts that have been compromised, and what you see is either a direct result of the account being hacked or that someone is using the account to add other stuff to the device (depends on what device it is whether thst is possible).

It's impossible to say more than that very general speculation without explaining what you see on these unnamed "smart devices" that makes you think they are compromised.

Slow ethernet reconnect times on samsung active 4 pro tablets.

Thanks for the enlightening write-up, this does clarify things.

Samsung Galaxy Tab Active4 Pro - Full tablet specifications

This is just speculation but I'm guessing the auto-connect delay is due to some kind of verification or authentication 'handshake' where those tablets are then involved in an exchange between each tablet with the main airMAX BaseStation in your office facility. Kind of reminds me of the annoyingly long time it takes to cold start a modem with a lot of today's ISPs.
Given your drivers could connect instantly by manually selecting the necessary WiFi network, why is this not possible with these Samsung tablets?
Click to expand...
Thanks! I'll do some more checking on that. We are using the radios at this site for better range. They are close to a town so we've got some interference w local ISPs and houses. We switched over to these radios about 4 years ago and ran w our windows PCs and software till about 2 years ago. The yard switched to our android app and surface tab a 2019s but after a few years those tablets were starting to fail so we updated to these active tablets. I'm thinking that our range has been dropping from interference and we are just starting to notice it. Maybe before that extra range was enough for the android to reconnect w out us noticing. We are using the same setup at other yards, and I think we've got better range there, so nothing ever fully disconnects.

If I had the drivers manually reconnect, I'd ha e to switch our radios out to stuff the tablets can connect to. Not out of the question, just a hassel when it had been working. The other issue is that a lot of our drivers are to impatient or not smart enough to do that. We have had a rocket m2 running and the trucks using WiFi, and part of the guys broke the tablets because they were frustrated that it wasn't "working" right.

We have a lot of solutions to problems that shouldn't exist at my job.

Root RIP ACE :(

updates don't guarantee security. Not updating also doesn't mean you're less secure. That's on you and how you use your devices. With the amount of data gathering done by stuff today, and most updated apps doing it, you're probably more private and secure on outdated software that no one cares about hacking.

For myself, the constant UI downgrades over the years ensures I'll never update again until skeuomorphism returns. I have absolutely zero interest in reliving DeskMate, VisiON or CP/M again.
Click to expand...
well updates will almost always include security updates as well as updates to the os. these security updates usually will patch up any loopholes or vulnerabilities in the os........thus keeping it more secure. it also means that it would be harder to root which is why you never update a phone if you plan on rooting it.

so yeah updates are important IMHO.
