[Q] random reboot/mms bug?

Hi there,
just wondering if anyone else are having issues of their phone randomly rebooting? does anyone know of a fix?
also, sending photos as an attachment does not work. in order to send a photo to anyone on your contact list.
found a work around by going through gallery and sending it directly from there.
if anyone know of a fix for either issues. the help would be greatly appreciated.
Thanks,
kevin

I've had several random reboots. Oddly enough, they usually occurred overnight when I wasn't using the phone. I would hear the vibration on my windowsill and saw it was rebooting. I did a factory reset yesterday and while in the midst of setting everything up on my phone, it rebooted again. I thought that maybe there was too much going on and it overloaded. But last night when I was out and not using my phone, it rebooted again. I'm gonna have to go to Verizon to swap the phone.

It keeps happening on mine, but almost always in the car while attached with BT. I'm wondering if BT has something to do with it, in my case.

Same thing
I am also experiencing the issue specifically at night. I have yet to actually have it interrupt me in anything but its still a concern. Just curious about whether for those of you who are experiencing it are using the Assist app or Android Assistant?

I only use the Assist app for when I'm in the car. It's not setup for night time. I exchanged my phone at Verizon today and so far so good. One of the employees tried telling me that the reboots could have been because I had Better Battery Stats installed on my phone and the battery saver apps can conflict with the OS. I blew his mind when I told him that BBS wasn't a battery saver app and simply lets people know about specific wakelocks. Seemed like no one there had any idea this phone even existed.
For the reboots, I guess tonight will be the big test.

It happened again to me this morning as soon as I got in the car and it connected to Bluetooth. Once it reboots, it's solid.

Please report back. I have gone 24 hours without a reboot with no changes to the device which is a first. If it doesn't have a Samsung or Apple logo no one seems to care anymore.

I can't get Assist to work at all. I typically listen to podcasts in the car and when texts come in I get a notification sound but I've never had one read to me. I disabled Assist to see if this was the cause of my Bluetooth reboots, and it's not.
With Assist disabled entirely, each time my phone pairs with Bluetooth it connects but the moment I start to play something it reboots. It's very consistent.

Just wanted to let everyone know that I haven't had any reboots with the new phone. I exchanged my old one for this one on Monday and so far everything's been good.

I have now had 3-4 random reboots that I have seen. I have also witnessed a complete lock up of the phone. I will be heading into Verizon today to exchange my phone.
Just wanted OP to know more people are having issues.

[Q]Anyone having issues with GPS?

As a previous owner of Samsung's Captivate, and Infuse I have had plenty of experience of how bad GPS can get.
Also having owned the Note 1 and Note 2 I was able to realize just how AWESOME GPS/GLONASS can be! My S2 was somewhere in between.
With EACH of the previous 5 AT&T devices I always left WI-FI assistance OFF for better accuracy with at times down to single digits of feet using a purchased app called GPS TEST PLUS.
Enter my two day old Note 3. It sees more than twenty satellites like my earlier Notes, but doesn't use nearly as many. GPS on Note 3 also seems to go to sleep in less than a couple minutes whereas all 5 earlier Galaxies didn't.
Google Maps starts to hone in and gets within several yards and then jumps a mile or so away before coming close again.
I have uninstalled/reinstalled gps app. Cleared/renewed agps data.
Full factory reset also without any improvement.
Accurate GPS is critical to me for marine navigation using Navionics app a couple of weeks each year on rental boats in FL Keys. Last spring we broke down and I sent owner an edited screen shot for him to come tow us.

Yes, I have noticed the same thing. Not sure what do about. I have also noticed that my signal quality is really lower than it used to be on Galaxy Note 2, as well.

Considering return within 14 days. Not acceptable for me especially if custom ROMs won't be available to improve upon.
Have not compared GN 1,2,& 3 FCC diagrams to see if GPS antenna was moved.

I also have the same issue. I explained this to an att store that the gps is half as good as it was on my s4 or note 2. Lock on in maps kept going in and out and when i drove, my arrow would be driving over houses. All they said was they can't do anything because they can see anything wrong. While maps is open it locks on but accuracy keeps fading in and out. Again i said well it's more noticeable when driving. He said that i should take a photo of it happening... and that Gps accuracy is normal within 100 feet. I looked at him in disgust and repeated "normal within 100 feet?". I basically lost my sh*t immediately after that grabbed my phone out of his hand and walked out. I have no idea what to do.

Same issue with my Note 3. Very inaccurate GPS. I have sent mine for repairs and if they can't solve it I will not keep it.

YEAP .mine does the same thing. Hear we go again with a galaxy and a gps ! Note 2 was flawless and this issue makes me miss that phone

This seems like a widespread issue and exchanging for another seems pointless. Right?

That's exactly what I would like to know, because I have a similar issue. For me, using google maps works great until it suddenly says "GPS Signal Lost" and stops working. If I turn off GPS and turn it back on, it gets a fix again pretty quickly, but this shouldn't happen so often. It happens at least once every time I use maps, and often it will happen multiple times.
I have the "GPS Essentials" app so I ran it alongside google maps and checked it when the signal got lost. The satellites basically went from a count of about 17 down to 0 and then started adding themselves back.
I was going to exchange my phone for an exact replacement tomorrow. But if this is a software issue or an issue effecting the hardware on all phones, then it doesn't make sense to exchange it. I'd really like to pinpoint the issue exactly. Has anyone managed to get rid of this issue completely?

Someone should try exctracting a old version of maps from a note 2 or note 1 rom, uncheck auto update in the play store and see if the older version of maps is any better or if it will even work. I'll give it a try.

I just exchanged my phone today for a new one because of the GPS issues I was having. I used google maps navigation twice since and didn't hear "GPS signal lost" once. Seems like my new one doesn't have the GPS problem, but it may be too soon to tell. It could just be that a significant portion of the Note 3's out there have buggy GPS chips and my new one has a good one.
Another thought I had was maybe it has something to do with software we all have installed. Did everyone who had this problem root their phones? My old phone was rooted with Root De La Vega. I also froze AT&T navigation. I'm hoping the problem doesn't return when I root the new phone and install all my apps, but we shall see.

Having mobile data "on" helped me improve the GPS signal on my Note 3

Thanks for posting your experiences.
My phone has been on repairs twice with no improvement. I will go back to the store tomorrow and give them one more chance to solve the issues before returning it permanently.
I love the phone in every possible way except for the poor gps. It looses the fix constantly even in places where the sky is clear and reception should be perfect.
Below is an example of note 3 vs S4 running the "GPS Status & Toolbox" app. Worth noting is that the Note 3 had been searching for a fix for 20 minutes while the S4 was booted up just seconds prior to the photo:
i43.tinypic.com/2a7781g.jpg (copy paste in browser)
Both phones having the same settings enabled (wifi, gps) and swapping their positions did nothing to improve the situation. 1 minute after the photo was taken the S4 was down to 3m accuracy. Note 3 never goes below 10.

I had the same issue, except I would lose the GPS signal every time I plugged the phone in. I would have a good signal then plug it in and it would drop the GPS. Even the GPS icon would disappear. I took it to the ATT store and they exchanged it. I don't have that issue anymore, although my compass app seems way and useless.

So that's more evidence that the hardware may be to blame... unless you had a profile manager or something that launched conflicting software when the phone was plugged in. Seems like poor QA on the GPS chips to me.
About your compass issue, I think you have to rotate the phone at least twice around each axis to get that to calibrate. Although that may be just with certain apps.

So I installed maps apk from a note 1 rom so I'll give it a try and report back if it is any better. Its a long shot but worth a try.

Just an update...
I rooted my phone again and installed all my apps, and my GPS still works perfectly. So basically my software stack is the exact same as it was when I had issues, but now the hardware is all new. This tells me the software is not to blame, and the GPS issue is most likely caused by a crappy GPS chip with poor quality control.
A word of advice: If you have GPS issues in your Note 3 and you're still within the 2 week window AT&T gives you for returning the phone, exchange it for a new one. It seems to have fixed my problem.

I was a pre-order (received it on the 4th) so I'm well past the 2 week window. I didn't really use the GPS until after I rooted with the initial Root De La Vega (MI1 FW). Then I noticed just terrible GPS performance (jumping around, poor refresh, losing lock, etc.) I re-rooted using the MI9 FW, and my GPS performance improved dramatically. My compass is still terrible. But I can navigate with Gmaps without always jumping to different streets. Just my experience.

For what it's worth, I rooted with MI9 on both phones. The first one had the GPS issues and the 2nd works perfectly.

[Q] Alarm Clock going off late

This is my first post/question.... ever here, so go easy on me. I've been searching the interwebs and can't seem to find anything similar to my problem.
As background (may not mean anything), a few days's ago I downloaded the new Bitspin Timely alarm clock after news of Google's purchase. At some point I made it the default clock when Google Now asked for the program to use when setting an alarm. I swear the alarm worked once or twice before all of this, but can't remember now.
Whatever happened, my morning alarm doesn't go off on time. Its always about 25 min late (sometime after I've woken the phone from daydream). I even tried switching back to the regular alarm clock, and it wont go off in the morning on time. Uninstalled Timely, still no dice.
The kicker is that when I test it during the day, everything works perfect. It's like the phone goes in to such a deep sleep (that's a thing, right?) overnight that it just doesn't catch the time in the morning. Thankfully I have a decent internal clock and have had the privilege of just watching the time pass the alarm time and nothing happen. My other thought was that maybe its related to Moto Assist. I set the do not disturb, but its set to end well before my alarm goes off. I've cleared its data and disabled that for tonight to see what happens.
I REALLY don't want to factory reset. And I can't root to use some of the detailed monitoring apps because my company makes us use that stupid Good for Enterprise.
Anyhow, if anyone has any thoughts, I'd appreciate it.

Haven't tried out my alarm clock yet but will set it up for tonight and see what happens. Hope that it works or I'll have to buy an alarm clock for my dorm room.

I'm just throwing this out there. Under Settings > Date and Time> is Automatic time chosen? Is the correct time zone chosen? Is it off by 25 minutes to your time vs you set it at 0600 and it goes off 0625?.

When in doubt try clearing the App Data and try again. I'd suggest testing the alarm before going to bed of course I use Timley too and have no real issues with it yef

I thought I had this fixed... worked perfect the night after I cleared cashe/data from the clock, timely, and moto assist. I even disabled the quiet time on the moto assist app. Worked great through Tuesday, but then yesterday it was 4 min late, then 35 min today. Its also a bit strange that when I look at the Timely widget, it was a little under a min behind the system time. I'm sort of at a loss at this point. Would this be software, or possibly hardware?

just curious what's wrong with the built-in alarm clock? i've been using it since it's been bundled with android and it works great.

I love the stock alarm clock as well. I should have been more clear with the issue. I tested both the stock and Timely alarms and both seem to suffer the same issue. So I don't think my problem is with the app itself, but rather however the alarms work.

I've been using Alarm Clock Plus (paid) and haven't had any problems with it setting off alarms at the set time.

I've been using Timely and the stock alarm with no issues on a nightly basis. It seems odd that yours isn't going off on time. Timely and the stock clock are always in sync on my Moto X. It sounds to me that you have no other choice but to try a factory reset. There is a glitch in the system somewhere.

Resurrected
I hate to resurrect an old, dead thread, but consider this one resurrected. I just had this exact same problem occur with my Samsung Note 2. The alarm went off late, (both stock alarm clock and Timely), and it's incrementally getting worse. I'm running an unofficial version of Lollipop, but the alarms worked perfectly up until this weekend.
Anyone have a solution, yet?

I was having this problem. Thought it was Amplify or Greenify. Tried everything. Then..... I discovered that somehow DayDreams was turned on. I turned it off and it immediately solved the issue for me.

Unfortunate
That is truly unfortunate to hear, as I use Timely and my clock with the Daydream function of Android every day. I dock my phone, and Daydream immediately kicks in the Timely clock as my sleeping screen saver. I will test this out to see if it's the problem.

[Q] Not getting notifications until...

Any one else have the problem of not getting notifications until you unlock the phone? I notice it also with facebook messenger, facebook, and not getting email either. Is this just me or someone else having this problem?

Mine does/did the same thing. Never figured out what it was. Now it is up for sell and I am using my newer HTC One. I think it might be the power saver but never got around to testing it. In PS mode it is supposed to turn data off when the phone is sleeping.

messing around with the settings and found it has something to do with the lock screen security. When its set to "none" the notifications works fine. I have tried a couple of the apps for screen locks and are not satisfied with them as far as thier looks. I am really hoping when ATT finally released the kit kat update it will fix this problem. I just sold my LG G2 to get this phone. Kinda disappointed now that ATT released its update today.
I used to have the HTC one but didnt like not having the sd card. I found I like the bigger screens.

Did you finally figure out the solution? I am completely stock, not rooted and have the same issue since last 6 months. I never had any lock screen, so thats not the issue, I always have my phone unlocked.
The problem is not app specific. The delay in notification happens all across the board. When my phone is sleeping, i dont get any notification. As soon as I wake it up, all notification come at the same time, including Yahoo mail, Gmail, hangout messages, whatsapp, Google voice, twitter and others.
It seems like the wifi/data is disabled when phone is sleeping. I double checked in the Advanced Wifi option that wifi is always on. Some people said that the push notification heartbeat might be the issue but why only few of us are seeing this issue and not everyone?
Anyone have any solution?

I have always had my Note 3 on PIN, and I always wake up to at least 2 or 3 emails (sometimes many more), and at least 2 or 3 days I wake up to a new text (I don't text people normally, but Amazon texts me to let me know an order has shipped, etc.)
So it's not the email or text app and it's not the lock screen "as a rule on all devices". It could be a few different things, like allowing wifi to be turned off when the screen is off (that saves so little battery it doesn't make any practical difference - turn it off and keep wifi on all the time). I don't normally run with 3G/4G on, but that shouldn't turn off during sleep, so it wouldn't cause the problem.

GPS navigation issues on two devices now

I got my original Note 4 last Sunday. Since I use GPS navigation quite often, it is always one of the first things I check out when getting a new device. I found that it didn't hold a lock for long, it takes a long time to get a lock again, and when it does lock it's not accurate at all. I got an exchange today, and the same exact thing is happening with my new unit. A friend told me this would be the best place to come for help. She mentioned that rooting and custom romming might be the fix. I haven't rooted since my MyTouch 4G, and I've never used a rom. Can I get some help with that?
Also, I've tried waze instead of Google maps and that didn't help. And yes, high accuracy is turned on.
Thanks in advance!

Bump - any advice? On a different forum, someone mentioned downloading a GPS fix app from the Play Store. I did that, and I'll check it out on the way home from work. But ultimately I'd like a device with strong GPS natively. I'll try to exchange it one more time. I find it really weird that I'm the only one that seems to be having these problems!

Are you the same penguin from the a/c forums?
Sorry to hear you're still having gps issues with your replacement phone. Silly question, but is high accuracy mode selected in the location settings? Is wifi enabled?
Have you tried installing GPS Status? How many satellites can you lock onto?

Yep, I'm the very same penguin . High accuracy mode is indeed enabled. I haven't tried it with wifi enabled, I usually disable it when I leave home to conserve battery life. I'll try keeping it enabled on my commute home tonight. I've installed GPS status and it locks on to like 13ish out of 20ish satellites (it fluctuates a bit) when I'm stationary so that's not a problem. I haven't tried seeing how many lock on when I'm driving since I don't want to fiddle with my phone that much when I'm on the road. I'm still trying to get one more replacement before my 14 days are up, but the day is approaching quickly, and none of the 7 or 8 stores in my immediate area ever have any in stock! I call every other day and I'm sure I'm driving the reps crazy lol.

I've had this same issue with my first Note 4 on TMo but replaced it last week and havent had any issues besides very occasionally having a slight hang after making a turn and the GPS not registering it for a few hundred feet.
On my first note 4 it would CONSTANTLY lose GPS signal and be wildly inaccurate (not recognizing my turns or the proper facing direction) but hopefully *knock on wood* its been fixed with my new phone. I know you've already exchanged it but...
If you find a fix, please post it here just in case

I had the same problem with the GPS, it was working only on wifi but not with the phone data. But after a full flash it is working fine again. Also, it was very laggy since the first day.

I had a thread around here for similar GPS issue.
I actually got a PM from someone called SamsungSupport.
Anyway I think this is a compass calibration issue.
I installed the GPS Status app and recalibrated the compass.
The next time I used it (yesterday), I didn't have any issues.
I don't know if it has resolved the problem and I'll keep monitoring it whenever I use GPS.

I got my second replacement yesterday, and it's even worse than my initial replacement!! It's as bad as my first device.
I chatted t-mo customer care today and they were of no help. They kept advising me to do the same troubleshooting issues I've already done. Then, I chatted Samsung care and the rep was A LOT more helpful than the previous Samsung rep I spoke with. Samsung has a remote app that you can download from the Play Store, and the Samsung rep can remote into your device and see what you're seeing. We couldn't do much at the time since I'm at work, but I'm set to chat them back right before I leave work. They're going to remote in with me and actually see the issue that I'm having while driving. HOPEFULLY a fix will come out of all this!!

Bump. I'm on my FOURTH replacement now, same issues. What is going on?? So far, I've:
Recalibrated the compass
Tightened the screws underneath the battery door (they seemed pretty tight anyway)
Samsung support reps haven't been able to work with me using the Smart Tutor (remote into my phone to see/manipulate what's on my screen) app. They always disconnect the session before I get on the road, or maybe the session just drops.
Factory resets
Clearing the cache
I got my firmware reflashed at a Samsung kiosk at Best Buy
Make sure high accuracy mode is enabled (these days I never take it off since I'm always fiddling with my GPS)
Tried a number of gps fix apps in the play store
They want me to send in the phone for repair, but I have this nagging feeling that they're going to turn it on, see that gps can indeed get a lock, and send it back. Plus, there's no guarantee that T-Mobile will have a smartphone loaner phone, since they say that those phones keep disappearing because there's only a $50 deposit, so people just take the phones (this is why we can't have nice things). Since no one else is reporting these issues, it's doubtful that Samsung is working on a software fix for it. I'm really REALLY enjoying this phone otherwise, but I NEED gps to work!!

Samsung Note 4 Issue with Waze
I just upgraded from the Note 3 to the Note 4 two days ago and I have the same issue. It took me a few hours but I figured what they have done. They have program the Note 4 for totally hands free driving and if you want to use a GPS program it will be the one they have. You have to activate CAR MODE and you will see and hear your Waze in the background come on line and start to work correctly. Then if you close their program quickly, you will see Waze running correctly for about 5 seconds and the go back to acting up without GPS signal. The GPS signal with high accuracy is tied to the CAR MODE.

TMOBILE will never offer a smartphone loaner as per policy. GPS works fine not sure what ur doing
