pinephone with lte-m chip and volte.

i'm not seriously proposing anything based on lte-m at this point. putting new model is already a design problem.

because battery life is bad as something in pinephone (pro). could lte-m based chip alleviate power usage? of course volte (voice over lte) needs to work for this case. lte-m data speeds are somewhere around 1Mbit/s, meaning that there are slow. frequency band support might be reduced as well. do people have some knowledge on this issue?

what i know, cpu is the biggest waster of battery for pinephone and pro. modem chip is the second waster. so the reduction of power usage is probably not big.

Using Manjaro-ARM-plasma-mobile-pinephone-beta15-rc4.img. Booting stops and reports

"rcu: blocking rcu_node structures (internal RCU debug):"

Other OS'es boot successfully.

Any suggestions?

Hello

On the pinebook pro, where to buy a new TFT and how to replace it?

the display was white for several hours and now it looks damaged.

Thanks / kind regards

What if we could prototype and test Touchscreen Apps in the Web Browser, before running on a real device like PinePhone?

In this presentation we explain how we compiled the LVGL Graphics Library to WebAssembly with Zig Compiler. We created a Feature Phone App in the Zig Programming Language that runs in the Web Browser, calling the LVGL Library in WebAssembly.

The same app also runs on PinePhone with NuttX. We hope that this will someday enable NuttX Apps to be created and tested easily in the Web Browser.

I kept the default Linux installation on the eMMC and an Android one on the SD.

For reasons, KDE uninstalled some vital components and eventually it crashes after boot. I tried to install some other OS (I tried a bunch) by flashing on two differents SDs but it keeps booting KDE (and crashing). Moreover, neither my Android installation is working anymore.

What I've already tried:
- changing SD
- booting from a USB pendrive (both USBs)
- unplugging the eMMC (this cause not booting at all, just a black screen)
- switching on and off the tiny switch that should disable the eMMC (it doesn't affect the boot, even if the eMMC should be disabled)
- tried with another daughterboard from another trashed Pinebook that doesn't work anymore, no effect
- tried with another eMMC from the same trashed Pinebook, with the default Linux installation. It boots and loads KDE but I can't use the OS because I don't know the passwords... besides there isn't nothing more than a firefox window... no menus, no internet, nothing else but the firefox window... weird, i can open a terminal but I can't do much because I don't know the sudo or root password. I checked with dmesg if it reads the USBs or the SDs, it detects them but I can't mount them because mount needs sudo

What's happening? why isn't working as it should?

Can someone tell me how to register my nick on Pine64's IRC network?
Normally "/msg NickServ <passwd> <email>" would work, but now I'm getting "NickServer: No such nick/channel"

And trying to post on any channel now apparently requires a registered nick otherwise you'll get a msg like the following:
"#Pine64: You must have a registered nick (+r) to talk on this channel (#pine64)"

I don't register my nick that often, so I may be doing sth wrong.
Or 'you' made having a registered nick a requirement without a working option to actually register?
I can understand taking measures to combat spam, but now I'm (also) blocked from using IRC

I have two Pinephones, one alpha and one beta. I’m trying to get the beta up and running but it does not send or receive calls. At first I though it was the sim because there was a similar problem on a normal phone but I’ve tried it out on the alpha phone and that one sends and receives calls just fine. On beta one I'm able to find the modem through mmcli. I currently have them on Manjaro KDE but I've also tried Ubuntu and Postmarket with the same results.

This presentation explains how we built the NuttX Drivers to support Touchscreen Apps on PINE64 PinePhone:

(1) MIPI DSI on Allwinner A64 SoC
(2) Allwinner Display Engine
(3) Goodix I2C Touch Panel
(4) Integration with LVGL Graphics Library

To derisk the development, we prototyped the NuttX Drivers in the Zig Programming Language, before rewriting to C.

Hello all!

My PBP arrived today. unfortunately… it appears to be dead on arrival. The power button did nothing. I plugged it in and that didn’t help. I tried holding down the power button. All that I have to go off of is a red LED indicator that comes on when I plug in the charger. Anything I should try? What do I do?

Hi all, this might be a daft question, but does anyone know of a screen that's readable in direct sunlight that can replace the pinetab screen?
I'm ideally looking for something brighter than the ipad pro (1600 nits), and ideally more like 2000 nits (like the samsung UDR 2000 displays, or DJI's CrystalSky monitors although I've no idea who manufactures their screens, or Gemlighttech's 3500 nit displays).

As I understand it, 1 nit = 1 candella per square cm.

My thanks for any thoughts anyone has on this.

If there's another open-source tablet with a more customiseable display I'd also gladly accept a steer.
