Is it a general custom ROM problem, Cyanogenmod specific problem or Lollipop problem?

After upgrading to the Note 4 back in March, I recently decided to dabble in the rooting and custom ROM world of Android back in late June - early July.

I've been using CM12.1 nightlies since July 19th and currently have the August 20th nightly. One problem I had is that if I tried to update CM via the CM updater under the "About Phone" section, I end up getting "No Service" for my mobile signal/data which meant reflashing the stock firmware and reflashing TWRP/Cyanogenmod. So if I wanted to update nightlies (no plans to until Android M), I would have to manually get the nightly zip files from my laptop then wipe my previous nightly clean so the mobile signal would still work.

But the biggest problem I (still) have now is that I simply can't send text messages ranging from 10 minutes to several hours (Would just be stuck at "Sending..." and eventually "Not sent. Touch to try again") only after I turn off/restart my phone or turn on airplane mode. It shows that I am still have connection to Sprint and I can actually use LTE/3g. Also interestingly enough, I can still call people AND receive their text messages, but I just can't send text messages.

It's not a big enough deal breaker for me where I would have to go back to stock ROM, but I'd like to know why this is the case. Since sending text messages seems to be the only problem, I assume it can't be the mobile signal itself since I'm still able to call, receive text messages, and use LTE/3g.

Things I've done/tried so far with no solutions:
1. Read older OPO/XDA threads about something called Voice+ causing the issue, but no such application exists on my CM.

2. Flashing the 5.1.1 firmware from Sammobile since CM12.1 is based off 5.1.1 Lollipop and I originally rooted and flashed CM12.1 with a 5.0.2 firmware. Problem still persists even on the 5.1.1 firmware

One final thing I will probably try to do is do an advanced wipe via TWRP, flash the stock 5.1.1 firmware and then get TWRP back via Odin and flash one nightly zip only and never attempt to update or flash new nightlies until Android M.

As for now, once I get my ability to text back again, I'm not going to turn on airplane mode or turn off/restart my phone and leave it be. I have a fair enough standby time with CM (2% drain in 7 hours or so) which is nice.

Any input would be greatly appreciated!

D855 bad battery? Restarts on specific times

So this issue has been happening randomly over the last two weeks and suddenly it started to happen on specific times.
Basically what happens is that my phone reboots when I open Snapchat or get a message on Messenger and I press on it right as I get it. It seems to also happen when the CPU jumps up a notch.
I think it is the battery because when the phone is plugged in and charging, it never reboots even if I open Snapchat. As soon as I remove the charger it will reboot while still in Snapchat...

As I said, I think the battery is faulty but I do not know how to be sure. Is there any apps or ADB commands to check my battery wear etc? I need to fix this because I need my phone everyday for school (doing a project which makes me need my phone all the time for verification), and I am waiting for the Moto X Style.

I've tried different ROMS and different kernals but nothing helped.

How to prevent specific apps from using data when signal is bad?

Some annoying apps use lots of mobile data when the signal is bad. Is there any tool could prevent a specific app from using data when the wifi signal isn't good?

Tablet turns itself ON at a specific time when in cradle

My Tab 4 turns itself on every night at specific time. I cannot figure out why, or what setting may be the culprit.

Every evening, I tap the power button to "sleep" my tablet before I put it in its cradle to charge. However, every evening at a specific time the tablet display lights up showing the lock screen, which wakes me up. This is making me nuts! I can't find any setting that would affect this behaviour, and there are no alarms set to "wake" the tablet at some specific time.

Any ideas where I should check?

Making a specific phone number "call" google voice search

Hi,
I'm wondering if it's possible to make an app that will catch a specific number if called and route the audio to other apps like googe voice search or s-voice. My one pet peeve is when I'm driving I can't start google voice search without interacting physically with my phone as the majority of autos I've seen like ford sync and subaru's off label BT systems have no way for you to do this built in. My idea is to design an app that puts a contact in your phone so you can just say "Call Google" or something similar and your car will initiate a call with the phone, but to have the phone not actually connect to the cell network but after call has been placed you hear the familiar "beep" of voice search. You know, like on windows phone you can say "Call Cortana" and she'll pick up. Or is that a special API only in windows phone?

Need quick info on modding Z2 & specific advices

Hello ya all

I got my Z2 out of some deal, and I need to ask you couple of things, but first to explain myself.

1. I ALWAYS prefer AOSP rather than anything manufacturer made. Till now I had all the Galaxy S models except S6 and I always went for AOSP/Slim versions of roms. Couldnt ever wrap my head around TW and I generally prefer that my phone runs on original android, closer to Vanilla.

2. what's the deal with unlocking BL .. ? I went over some threads but It is a bit overwhelming. I figured that I need to unlock the BL in order to use AOSPs ?

3. Is Sony's customization as annoying as TW .. ? As someone who never uses Sense or TW, Im probably not going to like whatever Sony is using also (xperia UI name .. ? ) ?

4. A friend recommended Pure X ROM, and told me it would be a partial solution for my needs, doenst require BL Unlock.. ?

Waht would you guys recommend for me .. ? should I go all the way and install AOSP or do you think there is a ROM that would suit me ? Thanks to all in advance

How to compile tun.ko module for specific kernel?

Hi,

I have EPSON MOVERIO glasses which have an Android device inside with kernel "3.0.21-00003-omap-android+". I want to install tun.ko module as they does not have it and therefore I cannot establish a VPN connection.

I tried with tun.ko installer but it won't find any tun.ko compiled for that specific kernel. Could you assist me in compiling it for that version? Or is it any other solution out of there? I really need it.

Thank you.

Samsung s6 ,lock a specific app on lock screen

Hi everyone , I hope someone can help me with this.
I hope there's an app or way to do it.
Basically i want to know whether is possible to lock an app on the lock screen so that it can be used but you can't exit it or use other apps without inserting patter code or lock code.

In this case I would like to be able to have my playlist on the lock scree so that even if some of my friends handles the phone ,they'll be able to scroll through the list of songs and use the music player but won't be able to do anything else unless they unlock the device

is something like this possible?(at the moment there's a small widget at the top of the screen that can be used to pause,next songs etc when the lock screen is on but it doesn't allow to have more access to the app features such as playlist songs etc)

Thank you
