Does anybody have problems with encryption? Once encrypted I cannot access the phone anymore because whenever I try to unlock it, it reboots on its own. The only solution was to format data and forget about encryption at all. Other than that the rom seems amazing!

Hi,

First of all, thanks for the fantastic work. I'm using it around 1 week and its super stable and fast, no issues so far, just one question: In previous versions of LineageOS you had the option to individually disable/enable sim card but now I can't find it. So my question is if there's a way of disabling a particular sim card without getting it out of the phone.

Thanks

Pin release not working

When pinning an app (via Recents/Overview) the button combination to release it (Back+Overview) is not working.

A reboot is necessary. :(

---------- Post added at 03:39 PM ---------- Previous post was at 03:30 PM ----------

This one was weird for me as well but I managed to fix it:

Enable Developer Options (click several times on Build version line in Settings->System->About Phone until you see the appropriate message).

enter it and under Networking hit "Default USB configuration". I had it set to "No data transfer" initially so I picked "File Transfer" and that was good for me.

[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] thumos2:
Many tjanks for replying. In which sense can a rom be unstable? How bad of a problem can this cause? And are old roms bad?

I can see, also, e.g. Havoc OS still supports 4 Prime.
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] Dn.Thanujaya91:
I tested most of the pie based roms (Havoc, Crdroid, Resurrection Remix), i experienced some common bugs that drive me away from those rom.

bug is if you enabled double tap to awake feature it'll awake the screen while it in your pocket, even there option called "check the proximity before awake" that doesn't work.

you can solve this by enabling pocket detection, but pocket detection will keep the processor awake all the time.

some of the these roms doesn't have night light mode or it's broken.

& the notification light kind of hit or miss

Ram usage also pretty high, you have to use memory killer (kernel adiutor)

these are not major bugs, but it annoys
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] thumos2:
Okay, I got your point. Looks like Crdroid is the rom to go for Markw. Thanks again.

One more question: if a rom is no longer maintained, how bad is it? Will I still get software updates? Will the rom support newer software?

[Samsung Galaxy A3, A5, A7 (2017) Questions & Answe] sciurius:
I have an A320-FL with an original Samsun NEON flip cover. The phone detects when I open and close the cover.

However, occasionally (sometimes: often) the phone seems to lose contact with the cover. It doesn't respond to opening and closing anymore, and the only way to get it working again is to remove the cover, reboot the phone, and mount the cover again.

This is very annoying! Even trivial actions like answering a call, or opening the clover while charging, may lead to losing cover functionality.

I cannot believe I am the only person with an A3 and NEON cover that has this problem, but my searches do not result in usuable information. There are some messages on the net that mention switching NFC on/off but this doesn't work for me.

Surprisingly, there are no settings to (re)detect a cover. Given that a reboot solves it, I suspect a software problem.

How to Flash

Place the zip on the internal/external memory.

boots into Recovery

then click on "install" in the TWRP

searches for the folder where the zip file was placed

and flashes it by clicking on the zip and dragging the slider to the right at the TWRP

rebooting

How do I change the boot logo in the template?

open the exynos9810_N9_logochanger zip (with WinRar or 7zip) and replace the logo. jpg with another image of your choice

the new image must be renamed to logo. jpg again. Otherwise it won't work!

How to return to the Stock logo?

You don't like the custom logos anymore?

then just flash the zip appropriate for your device:

exynos9810_N9_logochanger_Stock_S9 (for Galaxy Note 9)

Troubleshooting

If your hanging in a bootloop without access to twrp, please reflash the bootloader via odin. TWRP and system boots up again.

Note:

Not all images work, the best results are achieved if you just edit the stock image.

[Android Head-Units] LumpiZupf:
Hey,

I have been using an ownice c200 up until last year, when the unit let out the smoke and died. I am using the original RNS510 and that thing is driving me nuts… I am thinking of buying a new unit and have been browsing the forums here to find answers to the issues I will run into. It seems that to turn on the sound system and use the camera I would need 2 more special can adapters.

When I installed the ownice unit I did draw up a pcb with an rgb-composite converter but never came about to build it. Not having the camera was only a pain when I did hook up my trailer…

To turn on the amplifier I built a little µC box with a CAN Interface, debugged the bus with the original headunit in and then wrote a simple program that listens to specific commands, turns on the amplifier and also keeps it turned on. My intention by then was to find a way to send the commands via the CAN bus adapter that came with the c200 but since that little box in my glove compartment did the trick I never got around to investigate further. Also I am no andriod expert...

From what I have found here the communication to the CAN adapter is done via a serial interface. There are no actual can frames transmitted and all the filtering and conversion is done in the adapter. Maybe someone can point me to threads dealing with the CAN adapters. Has anyone here done a custom CAN Interface? Can you configure that interface to listen to more IDs? Can you get the raw CAN data from the interface?

My ultimate goal would be a can interface that gets configured via the headunit and then just forwards the commands in both directions. The rest would have to be done in software on the headunit.

Cheers,

Christian.
[Android Head-Units] 96carboard:
It sounds like you're mostly done with the hard part of the job already.

My suggestion would be to avoid trying to interface with the chinese radio, but rather to work around it using as much as you can of custom code.

From what I gather, you already are able to "send" most/all of what you need with your little uC rig, but now you probably want to send commands back to the radio, right? The best way to do that would be to implement an HID keyboard on the microcontroller. Just plug the uC into the USB, the radio recognizes it as a keyboard, and you can send in commands, like volume+/-, etc.

Note that you can use the standard outputs from the radio (like the AMP ON, ANTENNA ON, CAMERA ON, which are just 12v binary signals) to feed that data out to the microcontroller.
[Android Head-Units] LumpiZupf:
The reason behind all this is to get rid of all the extra canbus decoders to get everything working. I already had to put my can node inside the glove box because I could not fit it behind the radio. Since the unit can send and receive commands, why not write the software for the headunit instead the microcontroller. That way also others might benefit from it and it would be possible to play with the MFD.

[OnePlus 6 Questions & Answers] spartan268:
Im on EX. Using the stune boost recommended on the second post of his thread along with top app boost set to 1 so it gets pushed to the big cluster. Ultimate smoothness and no stutters whatsoever. I think the battery drain might be higher with the topapp setting but it lasts me the day anyways so I don't care.

I used bluspark before as well. Provided me with the best battery results but I did get some hiccups with it.

Radioactive was also speedy like EX. Didn't test it long enough to compare to the finer detail but I figured if it behaves similarly I may as well stick with EX since I'm already familiar with the work since the M7 days.

One of the perks of owning this phone it's the insane speed. I've tried Ex in the past, on the OPO mainly, to try to get some extra hours out of a worn out battery. I used to use blu on my N5 for the same reason, I remember enjoying it.
