When I first got my Pinephone Pro a little over two weeks ago, I removed my T-Mobile SIM card from my old phone, and inserted it in my Pinephone Pro. I enabled mobile data by setting the APN to fast.t-mobile.com in the phone's settings, and I recall that it seemed to work until I also enabled MMS by setting MMSC to http://mms.msg.eng.t-mobile.com/mms/wapenc in the Spacebar texting program. I was able to send MMSs, but at some point thereafter, data stopped working. Editing/deleting/recreating the APN setting, rebooting, and removing/reinserting the SIM all did not help, so I put the SIM back in my old phone. I was also disappointed that YouTube videos in the Angelfish browser skipped (even over Wi-Fi), and were therefore basically unwatchable/unlistenable. I didn't get a chance to test the Pinephone Pro again until yesterday.

Well yesterday and today... data and MMS suddenly work fine. There are two reception symbols in the status bar, and one has a little "L" on it. I don't know what the "L" stands for, but I presume that symbol is for mobile data, because it gets replaced by a Wi-Fi symbol when Wi-Fi is enabled (which must mean the reception symbol without an L is for regular voice coverage). And YouTube videos suddenly play at 1080p in Angelfish over mobile data and Wi-Fi with no skipping now, which is great. However, on the phone's pull-down quick settings menu, the "Mobile Data" button usually says "Off", even when the "Mobile Data" switch is enabled deeper inside the "Cellular Network" settings, the symbol with the "L" is in the status bar, Wi-Fi is off, and data appears to be working. I'm inclined to chalk that up to Plasma Mobile being buggy (as it has plenty of other UI bugs).

Unfortunately, outgoing voice quality is awful. On a call between the Pinephone Pro with T-Mobile and an iPhone with Metro (which is owned by T-Mobile), the iPhone can be heard fine on the Pinephone Pro, but listening on the iPhone the Pinephone Pro sounds like it's at a harsh noise concert. Yes, this is with muting one microphone or going to separate locations to make sure there is no feedback loop. I'm worried there could be a hardware problem with the Pinephone Pro's microphone, and if so I don't know if the Factory Test Build for Hardware Checking would detect it since the mic technically "works", but I'm going to try running the FTB. Also, the phone died when it said the battery was 33% full.

1) Has anyone else used a Pinephone Pro with T-Mobile in the US, and can you comment on your experience?
2) Might upgrading to biktorgj's custom modem firmware alleviate any of the issues I've experienced?
3) Might changing out Manjaro + Plasma Mobile for Gentoo + Wayland + SXMO alleviate anything?
(My x86 laptop runs Gentoo + Wayland + Sway, and I already have experience cross-compiling for ARM for a Raspberry Pi).

My Pinephone Pro arrived with a small air bubble underneath the pre-installed screen protector, which is mildly irritating.



1) Is this common?




It came with a spare screen protector, but I'm not confident in my ability to install it without trapping air or dust underneath. I thought that unlike the original Pinephone, the Pinephone Pro doesn't need a screen protector anyway due to the Gorilla Glass display.




2) Can anyone who has removed the factory installed screen protector from the Pinephone Pro comment on the display's durability against scratches?

Hi folks, I've had my PP for a while now, I've run Manjaro Plasma, PmOS Sxmo, and recently Mobian Phosh.

While I still like my PP and ssh'ing into my phone never gets old, lately I have to admit I don't really use it as a phone.

So I'm looking for the "non-phone" OS. The NonPhone perhaps. I've done some searching on this topic but haven't turned up anything yet.

The goal would be to write/modify apps for it, just not typical "phone apps" like a web browser, maps, messaging, etc. So I would still like a well performing UI, touch gestures, etc. Think of it as a mini computer with a touch screen.

What are my options?

I'm the main developer of Castle Game Engine, an open-source 3D and 2D game engine, featuring visual editor, writing code in modern Object Pascal, cross-platform (desktop, mobile, consoles). I'm a happy owner of a PineTab2 since ~week, and I was happy to set up my full work environment on PineTab2! So everyone can use and/or develop the engine, and games using it, on PineTab2.

And thus our downloads prominently feature an option to download ready engine for PineTab2. (It's the same download as we have for Raspberry Pi 64-bit, as they are both "just Linux or Aarch64" for us).

I wrote an official announcement about it here: https://castle-engine.io/wp/2023/12/13/c...om-pine64/ . We have a significant community of people interested in "open-source gadgets", so running the engine on devices like PINE64 or Raspberry Pi definitely sparks an interest among our users.

If you have any questions, about the engine or how it works with PineTab2 or Linux/Aarch64, I'm happy to talk, on this forum or on CGE forum or Discord. This is the project of my life, practically, I love to talk about it If you want to read, our website lists features and has links to tutorial and the manual.

( Please excuse me if this is not an appropriate post for this forum, or should be moved to other section. Castle Game Engine is a free and open-source project. But I'm not independent, I am the main CGE developer. )

Trying to find a solution for the broken case, I broke also the display flat cable. I pulled it, supposing it was a connector, but it was soldered!

Now, I would like to use the HDMI interface, but there should be something to do to activate it, because when I boot, it doesn't give any signal. Anyone has an idea on what I can do?

Hi to everyone on this forum!

I found PINE64 searching the internet of some better alternative to the RPI and I think I found what I need: the Quartz64 Model-B. I've searched this forum, the website, the blog and I'm still looking for - hopefully - simple answers to these questions:

• I could not find any mention of the 8GB version of Quartz64 Model-B regarding availability. Did I miss something?
  
• Is there a summary of what is currently not working / still needs work regarding hardware support? I found a lot of old (2021) information.
  

Is there already a working OS for the pinetab RISC-V  version?

Hello all,

alright I read the wiki concerning flashing wasp Os thoroughly. 
But in the process already the first step doesn't work:

I use daflasher. The device is recognized instantly. But when I try to send dafitbootloader23 Hacked.bin
Daflasher says that this is no bin file.

I downloaded the bootloader several times. It is always the same.

Can someone help me here?

Thanks and take care!

Last week we walked through the Serial Console for Pine64 Ox64 BL808 64-bit RISC-V Single-Board Computer. And we hit some illogical impossible problems on Apache NuttX RTOS (Real-Time Operating System)...

(1) Console Input is always empty. (Can’t enter any Console Commands)
(2) Interrupt Claim is forever 0. (Ox64 won’t tell us which Interrupt was fired!)
(3) Leaky Writes are mushing up adjacent Interrupt Registers. (Or maybe Leaky Reads?)

Today we discover the One Single Culprit behind all this rowdy mischief: Weak Ordering in the MMU! (Memory Management Unit)

Here’s how we solved the baffling mystery:
Fixed the UART Interrupt and Platform-Level Interrupt Controller (Ox64 BL808)

Long sad story short:
Ny father passed feb 2023. I had a voice mail he'd left at the end of 2022. I have saved it and resaved it each time i access voicemail and listen to it for months after my dad passsed.  It was a bittersweet fix for missing him.  Then a few weeks ago it wasn't there any more. Ii may have accidentally deleted it, I don't know.  It seems that T-mobile tech support isn't equipped to help me.
Can anyone on the forum tell me exactly where the voicemail may be stored? I know the text messages are stored and are still on the phone in a folder in Purple.  But the voice messages? Dare I hope that they are also somewhere on my phone? 

Thank you for you input.
