Giving it a shot

I'm not a big camera user anyway, so I'm going to give this a shot. Wish me luck!

Hi there..
Is 4g/Lte working?

 

[DevMonkey]

4g LTE dont work

 

[SergiuStatache]

Great job!

Thanks for your work! This ROM is awesome and if you fix the camera too you're a god. By the way... on this forum there is another Lollipop ROM (Candyrom) where the camera is working. Can you use that? i'm a noob so don't judge me

Just flashed earlier today and seems to be working great! cheers man. Any update on the camera?
Thanks

Camera Works!!!

Great job!!! The camera works and the system is very fluid. i notice some problems on activating mobile data. First time i tried it didn't work. I switch some APN, turned Airplane mode on/off (strange, it required me to enter the PIN 2 times in a row). Finally it worked (i saw the LTE text on signal bars and i was happy ). Another thing i noticed is that the Prefered Network was 3G and i couln'd choose LTE only if i select 2G first and then LTE.

Thanks again!

no sim found

i have a problem, the rom can't find my sim, anyone had a solution?

 

[Ayki]

SIM

(This rom doesn't ask for my PIN so I guess it doesn't read my SIM at all? Clean install (I guess), everything else I tried is working quite fine.)

Settings say baseband version is unknown.

 

[SergiuStatache]

They can't hear me well

Another problem that i noticed is that the other person i'm talking to hears me, and i quote them, "like you are in a tunnel". At first i thought that is their phone, but multiple persons reported that to me. Also, this happened after i flashed this rom.

Baseband Unknown

Hi,
Just installed this and everything works great except for the mobile network. Settings say baseband version "Unknown", doesn't detect sim at all.
Does anyone has any idea on how to fix it?
Cheers!

....

Hello , I friend says to me : "You don't need root to install cyanogenmod on m4 , only TWRP (teamwin or something like this..) "
And my question is : Is this real ? I don't need root , only TWRP? to install cyanogenmod on m4 ?

 

[ricardooldy]

Installing the app Selinux and setting it to permissive fixes APN and mobile network problems. I would advise doing some background reading of this app first though.

 

[JelleZon]

Flashed it 2 days ago, everything is fine. Sometimes it is a bit laggy, but it looks very nice!
First i had problems with the google play music app. I was not able to listen to music with my headphones but now it works... Don't know why ?

Hello Guys,
I just tested the CM12 build for the One m4 and i have some issues... i cant connect to my carrier and somehow i can't install the gapps. i downloaded the one provided in the first post and i tried to download the most recent ones. If i try to install the gapps, my recovery just pops up the main menu with no error-codes or something. it is just loke blown away, if you know what i mean... and, yeah, i cant connect to my carrier, which is like... meh... not actually good for daily use... :/ if there is a way to fix it all, please let me know, i could use some help here.

Greetings Meritili

Edit:
Managed to install the gapps, carrier Problem is still there, help please!

Bluetooth Problems

Hi, first of all thanks for providing this ROM. I tried both the 5.0 as well as the fresh 5.1 build and most things, apart from some spontanious reboots, are working exceptionally well (IMO better than CM11).

One problem I observed is that I can't use bluetooth to make calls. I am not sure, whether this is a general CM12 problem, or whether it's specific to our device. The same problem is also present when using the other Lollipop ROM based on CM12 in the forum (Candy5). I also found some reports of users of other devices that also have bluetooth problems when using CM12 or some other Android 5.x based ROM.

To clarify: I can pair and connect to bluetooth devices that offer headset functionality (tried bluetooth headset and bluetooth radio in car), and I can also stream music via bluetooth. What I can't do is making actual calls via bluetooth. Both bluetooth devices noticed that a call is about to be made, and also the correct number was displayed in the radio display. But no sound was audible and the other side couldn't hear me. The call itself was okay when switching to internal speakers. Dis-/Re-enabling of bluetooth options did not fix anything.
Audio playback over bluetooth is also rather sluggish and sometimes leads to freezes. Also sometimes the option to use bluetooth for media playback has to be disabled and reenabled for it to work.

Unfortunately I can only test bluetooth in my car (the headset wasn't mine) so it is kinda hard to generate logs. I will try over the next few days to produce one.
