[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] yoshinatsu:
I'm having an issue with the signal.

When I first installed the ROM, the "preferred network type" was set to 3G instead of LTE. I thought that was kind of weird.

I tried setting it to LTE, and I couldn't get service. Then I switched to 3G again, and I got service. I set it to LTE again, reboot, still no service.

So I figured out I have to switch to 3G and LTE back and forth, or switch the APNs a few times until I connect to LTE service.

I wasn't having this issue on AICP 10. Is this just me or does anyone has this too?

Note that I'm only using one SIM card, in slot 1 (if that makes any difference).
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] genesisalgor:
Have that issue too, the problem is if there is no LTE signal phone should switch to 3G, but when LTE is set it suddenly stops getting any service.

Also 1 sim.
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] yoshinatsu:
I think I fixed it now.

I edited something on my APN, and after I rebooted a few times there was a message asking me which SIM card should be the default (I only have one, lol).

I think this message actually has to do with this bug, I think I had encountered it before on Jiayu.de's Lollipop RCs.

Also, have you tried using the FM radio, then switch it off, and try another app that outputs audio?

Any app. YouTube, a music player, even your phone's ringtone. The audio will play pitched down.

It's pretty funny, but it's a bug that's been there since AICP 10. You have to reboot to revert back to normal audio.
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] genesisalgor:
Honestly I never used Radio on this phone hehe
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] yoshinatsu:
Yeah, I never used it either, I'm just always checking everything in new ROMs to see if everything is functioning properly just in case I need them.

All the usual suspects, Wi-Fi Hotspot, Bluetooth, LTE reception, FM radio, stereo speaker, microphones, camcorder framerate, etc.
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] Borizzz:
Btw, could you upload some photos from AICP11 and fullhd video sample (pls don't upload it to youtube, give a file)?
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] yoshinatsu:
Image quality is exactly the same as AICP 10, if you had tried that before.

Which isn't bad (at least for this phone). Only negative thing is that on the stock app, you can't disable the image stabilization for video recording, and you don't have guidelines.

Just like it was on AICP 10. You'll need to use a third-party camera app for those things.

Secondly, if you want to update it to the latest version, you can use Lucky Patcher, which can overwrite apps with different signatures.

[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] Tarmo2011:
I just noticed that (for some reason) installing AICP 11 over AICP 10 ****ed up my phones internal memory. I wiped cache and dalvik, installed AICP 11 and did an factory reset and pretty much everything is working (except 3G 900mhz has extremely poor (non-existent) reception and there is no hope for 4G even tho I live in extremely strong 4G area) but one thing isn't working: The phone states that I have under 1G of storage left and few times the phone has even stopped working because the storage ran under 100mb. I don't have many programs installed and all my media is now on SD card. I started investigating and noticed that somehow my internal storage is ****ed up: I installed total commander and noticed that I have following "internal memories" and I know that they really aren't there but they are kind of a link to real files: /storage/emulated/0, /storage/408C-1300/ and ///_sdcard1

Well... the one thing that I noticed that the folders do not match. Same folder followed from the emulated differs from the same folder in /408C-1300, IE I have some videos in 408C-1300 that won't show up in emulated/0. And yes, I did check the folders, and it's not me who is messed up.

I also noticed that my music player won't play the music files that I had before AICP 11 and those were carried over, it just freezes... They, for some reason, show up in my music player, but won't play, they just freeze whole device for a while. Also removing files from these folders (those that won't show in emulated) don't free up space... so even currently I have bare minimum installed software and still under 1G free storage...

My guess is that I have a dirty install... should have I wiped whole internal memory from TWRP before installing AICP 11? I thought wipe cache&dalvic and factory reset was enough?

And if I wipe whole internal memory does it wipe my IMEIs too? Any other solutions?

I think I need reinstall AICP 11 soon, but has anyone else encountered this problem?

I've been almost a week with CM13, before that with Paranoid and since Monday with AICP13. I just wanted to share that I'm impressed with the battery. I have lots of apps, 4 email accounts, Wi-Fi on, data, sync,viber,whatsup,skype,messenger etc. Here are the results

Thanks for watching[emoji3]
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] cyberdejy:
I will be happy if my battery drops with 1℅ per hour. once again this is without usage while I'm sleeping for example.

[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] jaunedoeuf:
Here's what I would do.

But don't blame me if something goes wrong ...

Backup imei with mobileuncle to SD card (even copy it on a paper)

Backup everything with titanium backup to SD card

copy everything that you do not want to loose from internal memory to the SD card

remove the SD card and backup it's content to your PC

format the SD card with exFAT

install RC5 with flashtool with format option (I know, don't do that, bla bla bla)

boot to see if storage is OK

If storage is OK, then put aicp11 mm zip + gapps to the sd card and reboot in recovery mode.

install aicp11 + gapps in the same time and reboot

Now, you can restore imei with mobileuncle

About TTB, just restore important things, no everything because it will probably messing things up.

For the most part, just install the apps from the store.

Copy back your importants files (probably audio, video & pictures) back to your sd card.

Once again, do this a your own risk.
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] Tarmo2011:
Thanks for info, I was thinking something like this.

Just out of curiosity, why do I need to flash RC5? Can't I just wipe my internal storage from TWRP and reinstall AICP 11?
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] jaunedoeuf:
Well, if your internal storage is messed up and report wrong size, wiping will only remove files from it, not repare it.

Flashtool will create the partitions again, not just format them.

I use the format option (once again, I know, don't do it , bla bla bla) just to be sure.

And as aicp11 does not come in flash tool mode, your only choice is to flash another LP rom.

RC5, xtreme or any offical rom under 5.1 will do the trick
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] Tarmo2011:
Ok thanks for your help. I'll try this or I will try TWRP wipe first just to see it out (never done it).
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] AlexZap:
You could also use the firmware upgrade option. It will recreate partitions, but it will be constructive with things like the nvram and preloader. I don't know if it backs them up and rewrites them, or just partitions around them, but it will totally recreate and rewrite your partition table.
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] Tarmo2011:
How to backup IMEI? I can't seem to get access to engineering mode and apps in store require that before they work.

I have also tried dialer * # * # 3646633 # * # * or *#4634# etc but they don't work.

Also Unclemobile tools aint in play store, does anyone know good site to download it?
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] Pirex69:
Backup with twrp. Choose nvram.

Enviado do meu s3 através de Tapatalk
[JiaYu S3 ROMs, Kernels, Recoveries, & Other Develo] AlexZap:
You could use the jiayu.es app to backup nvram. Always a good idea, but as I said, if you use firmware upgrade in spflashtool, your nvram should be totally fine.

By the way, your nvram is more then your imei. It is MAC address for your network card, the hardware address for your Bluetooth, addresses for your NFC, and other bits of stuff for your phone like hardware volume levels. You really need a full nvram backup and not just the imei.

So, I got the media bug today (on Build 1) after more than 2 weeks of usage.

And I can't really deduce what made it happen. I just left the phone on standby when I slept, and when I woke up, I went to play a song on my music player, and I couldn't hear it. The progress bar wouldn't even move.

Tried YouTube, and the videos wouldn't stream at all.

Tried adjusting the ringtone volume from the system settings to see if the phone outputs any audio at all... Nope.

No sound. The phone almost froze when I tried adjusting the volume.

I would have been really screwed if I had relied on the phone's alarm today.

That's the first time this happened.

Had to reboot :rolleyes:

BT is working now on my Amundsen so I'm 'Xtreemly' happy with that ?

Small issue: Provider name is failing both on the phone (show on the topbar enabled) as well as on the car radio/mfa display. Instead of showing the provider name, providerID like '20601' is projected at the radio and on the phone it always shows provider name 'Vodafone NL' of the sim inserted, even when I'm roaming. (R visible)

Surely it would be nice tot have that fixed in some future build, but most important for now BT connecting issue have been fixed, which is definitely a well done guys! Cheers ?

Note: Just found out as long as I'm not roaming on the radio providename will be shown correctly 'Vodafone NL'

Another issue I'm experiencing is about searching available networks. It's not working and the phone will show "no network found". I think I've read it's a MM issue somewhere before, but because of this I'm not able to lock my national operator "Vodafone". I can't find another option to disable connections with a international roaming provider like "Proximus". Is that something likely to be fixed on a future build?

Great job, I suppose poor Sim signal is due to some unused bands.

I. E. If you choose just 2000 3g I have 3g signal, but if I choose 900 I have no signal and so uses 2g (I cannot test 4g). This doesn't happen in 4.4 or 5.1. I tried various modem and it works on cm 12 modem.

The turn in development for the past couple of months plus the open source battle won - amazing job guys!

Just wanted to drop in the issues I've spotted:

- Sim Cards Available Networks search does not turn up any results so unable to lock on a network (as someone mentioned, even on Build 2)

- Band Mode selection for SIM cards does not work. When you deselect some options, hit "Set" the UI just resets its state (However the SIM seems to be reset, as the reception drops and then reconnects).

- When I disabled SIM1, I was unable to turn it back on. It was just like the option was masked/disabled. After restart I was able to turn it back on (this may be a custom theme issue though).

- I have an app: MyBackup. It has trouble finding the SD card. Is it a MM change, app or this port issue?

Does it make sense to backport any changes from Verveka kernel since he dropped development? I just saw this:

-CONFIG_CUSTOM_KERNEL_IMGSENSOR="imx135_mipi_raw ov5648_mipi_raw s5k2p8_mipi_raw"

+# CONFIG_CUSTOM_KERNEL_IMGSENSOR="imx135_mipi_raw ov5648_mipi_raw s5k2p8_mipi_raw"
