"Information about prevention" driving me insane..

Edit: Sorry I just realized I posted this in the wrong section. Sorry about that.
Hello guys, =)
I currently have my SGS4 (GT-i9505) since release and haven't upgraded firmware since then (I was rooted). Everything worked fine until I noticed that when 4G became available in my area I didn't receive it. Then after a few google hits, it said I had to update so 4G would become active. Did that and flashed I9505XXUDMH8.
Everything went fine for one thing however. Immediately upon reboot my launcher (apex launcher) would force close. Then a message would show up telling me it has been forced closed due to suspicious behavior. Now, this wouldn't be much of a problem if it was just the launcher, but it happens to every damn app.
Anything that can get root access or can adjust system settings gets shut down right from the start. I've tried reflashing the firmware, resetting factory settings and I've searched a couple of hours on the web but I couldn't find anything helpful. It seems to be triggered by a new Samsung security feature (or perhaps even KNOX).
Is there any trick to get rid of this? Because I REALLY do not want Samsung telling me what I can and can not do with my phone. Otherwise I would get an iPhone. I really need to bypass this filthy mechanic one way or another (without removing 4G support) so that I can use backups without a problem.
Thanks in advance!
Shuji.

[Q] S4 - disconnecting from network and not reconnecting again

Hi all,
Regular reader but hardly ever post!
I have a Galaxy S4 (GT-I9505) - with Android 4.4.2. Unrooted.
Purchased and used in Singapore on the Starhub network since around October 2013. Everything was working fine until approx Feb or March when the latest Android version, 4.4.2 got rolled out.
Ever since then I am experiencing regular disconnections from the network. But the phone does not re-connect back to the network again, the only fix is to restart the phone.
These disconnections are often once or twice a day, and are very frustrating because if I don't notice it, I may be off the network for hours before noticing it - and are therefore missing out on calls emails etc etc.
This only happened after the Android 4.4.2 got rolled out, so I am pretty confident this is the cause of the problem.
What I tried myself to fix:
- restore APN's back to default state
- Factory reset (both via settings, and via boot screen)
What I have been able to narrow down troubleshooting, is:
- Disconnects seem to only happen when Network Mode is "LTE/WCDMA/GSM (auto connect)"
- If I use network mode "WCDMA/GSM (auto connect)" the disconnections have not happened (yet!)
- When the disconnection does happen in the first mode, I cannot manually change the network mode. The radio buttons are greyed out, and if I try to select "WCDMA/GSM auto connect" the request times out (I forget the exact message - it does respond to the tap but then nothing happens)
So it seems to me this is some sort of software bug/fault introduced with Android 4.4.2 that affects 4G connections.
After that, I have taken it to Samsung for warranty service. I have now had 4 visits to them and they have not been able to fix it yet. This is what they have done so far:
- First visit - factory reset (despite telling them I already did that) - did not fix
- Second visit - checked hardware and replaced mainboard. Did not fix.
- Third visit - checked hardware again and factory reset again. Did not fix.
- Fourth visit - who knows. I think same as visit three but done via a Service Manager instead of staff, Did not fix.
When I first called them back in Feb or March, they said it was a "known Issue' and sugegsted to "wait for a patch". However since visiting them, they said the known issue was only with Note 3's (not with S4's) and replacing the mainboard on the Note 3's fixed the problem. In my case replacing the mainboard - twice - has not fixed it.
I'm getting very annoyed with Samsung who seem to just be trying the same thing each time and are not fixing it. Staying in 3G only mode is a workaround but not an acceptable solution.
Now they've asked me to take if back again - for a 5th time.
Beginning to wish I had never bought the S4, or at least never got Android 4.4.2.
So I thought I would turn to here for help instead, I think you guys and gals probably know more than the Samsung service staff!
Any suggestions?
By the way, I don't run any memory/battery saver apps. I do run one data usage monitoring app that I thought perhaps was conflicting, so I tried not installing it after one of the resets, but the problem continued.

you CAN try other modem flash, but be careful with your warranty.
I do not know about the warranty conditions in your country, but in EU normally 3 unsuccessful repairs = phone refund or replacement.

I would try reflashing stock file or just flash a different modem

Hello, just like you i have been reading the post but never posting because i just came here to learn, nothing to share from this side...sorry.
But i am having the same problem as you. I bought my phone in Switzerland on march 2013 but i live in Uruguay. I was just thrilled with my s4 until the 4.4.2 update came out. My connection keeps on crashing and it doesnt matter if its on 4g or 3g just make me miserable all day. Only the two of us is having this type of problem??
I believe is some kind of issue with the new bootloader i just updated with a patched rom that came for Germany last week (the one with kids mode) the phone work fine for a hours and then crashes, so this update didnt work. I have also flashed very differents official roms and modems but nothin seem to affect the problem.
I have another problem even though my s4 is 4g i cant connect to 4g network, every configuration is fine i just cant connect, any thougths??
Thank you very much.
Sorry for my english.

I should add, I took it in *again* to Samsung, to the Service Manager. Said they would replace the antenna and try that, which they did.
Still have the same problem though.
Not sure who to believe, Samsung are starting to run out of ideas and starting to say it may be a network issue. But if the network is down, then the phone should automatically reconnect once the network is back available again. And it doesn't.
I'm convinced it's a bug introduced with KitKat, as the problem only started then, but of course I cannot prove it...

Sounds very similar to my problem, that it just started with Kitkat only. I'm sure it can't be just us two having this problem! I don't have anything special or different installed on my phone, and it's too suspicious that it was working fine, 100% perfectly until the KitKat software came out...

I know it just cant be the two of us from such diferent places in the world but, i just cant find any similar in any post or google. It has been almost 3 months from the update an me using another phone...

Well I thought I would post again to close the loop.
After Samsung tried 5 times to fix my phone, checking hardware and trying to reinstall the OS with no luck, they suggested I try replacing my SIM card.
Surprise surprise, it has fixed the problem with no recurrence yet after a week so far.
I still don't understand how the sim card could be the problem, especially as my phone was working perfectly right up to the Kitkat software update. All I can assume is somehow KitKat either had an incompatibility with my simcard (maybe the new sim is technically slightly different?) or maybe KitKat somehow changed something on the simcard, if that's even possible.
Interestingly, I did contact my telco first, and they told me to contact Samsung. As it turned out, the fix was in the control of the telcom right from day one.
Anyway, so far the problem is resolved, so I thought I would post this here to help anyone that may have this problem.

N900v activation issue.

Hi everybody,
I bought a note 3 from Verizon about one year ago, I started to have an WIFI issue that was not able to turn on (the button stayed in black-gray but never changed to on state), I thought with a hard reset that should be fixed but didn't remember that I had activated the activation lock(In that moment I was using stock lilipop), when the phone came up again I still wasn't able to access the WIFI so I'm stuck in there, I have tried flashing older ROM versions with no luck, the behavior was the same, do you know is this is a common issue or if there is anyway that I can modify a file in the system to fix this issue?, I'm in the Dominican Republic so I can't use the Verizon network to activate it.
Stock Android versions that I have tried:
4.4.2
4.4.4
5.0
In this screen it is supposed to show me all the available networks but instead when I press the Refresh button is saying this message but there is no wifi button to turn it on.

Thanks in advance for your help.

I presume the turn on wifi note at the bottom is not an active button and settings->general->wifi won't activate.
My first guess, all else being equal, is that the WiFi radio died.

I thought that but how can happen suddenly like that?, I was looking in the Internet and I see this is a common issue in Samsung phones but some of them can be fixed so I would like to test everything before buying a new phone.

That's how most electronic parts work these days, they either work or don't.
If it was working, and suddenly stopped, with nothing else changed.. That's a good indication the radio itself crapped out.

[Help VZ995] - MMS works, SMS not so much (resolved)

[Resolved] I used the Dirty Santa method to root and load TWRP; still on what's left of the factory ROM. So far the only issue I'm having (other than the known quirks) is with SMS. MMS seems to be trucking along w/o problems. SMS was working all day yesterday then it decided to give me the no-service toast message this morning. I've been poking around the forums for solutions, but most of the search results are Sprint-specific. I think it's a PRL/APN issue, but I have to use Shortcut Master Lite to even get a peek at the info. I'm not even sure if I've been in the right areas at that. I fumbled around and got SMS working again a few minutes ago and have no idea what I did or if it'll stick. TIA for any insight the community can give me.

I'd KDZ and get back to stock. If that issues still persists it may be something wrong with your device.

I was afraid someone would say that. Have to go research the process and hope there isn't an OTA lurking about that blocks D.S.
Seems that the SMS connectivity is lost after a reboot. Wish I could figure out what I changed last time that got it working.
About Phone says mobile network is connected as long as wifi is off.

I'm almost ready to revert and root again. Does anyone have a link to the Verizon APN settings? I seem to find references to every other carrier's info except "Big Red"
Edit: Found this in a Pixel forum. ZVW APN Info
So far it seems to have worked and has survived one reboot. :fingers-crossed::fingers-crossed:

Bad reception - Delayed text messages - Rooted phone the cause?

Hello!
I have trouble with my One plus 6 t receiving text messages. I receive them a day late, all coming through at the same time in a bulk of messages the next day. I changed my sim card so T mobile doesn't seem to be the cause of it. Are these problems because I rooted my phone? If so what is the solution? Thank you!

My 6T is also rooted and at one point I has service issues (on Verizon) I tried all my mods one at a time till I figured out witch mod caused it and I was shocked to find out it was my substratum themes messing with something. Once removed all was grand. Hope this help. Go one by one through any mods in place disabling them see if it helps.

The problem is that I have a lot of apps...Did you disable them one by one? And also I realise that I receive the delayed messages 1 day after so it's not easy to check. So the problem comes from the fact that my phone is rooted? Also when I use the camera my phone closes sometimes, like 30 sec after...Very weird. Does all this come from the rooting? Never heard of this problem before.

Yes I did dilisabled one at a time and rebooted after each one. And for text delay who is your carrier I'm on Verizon and mine was delayed for a hour or so till I figured it out I'd quick text my self hi from my own number and hit home to close the messages app out so I could time the reply time.
This helped me also.

Try turning off battery Optimization See if that helps, Could be just a delay with your signal... Had that happen before, I had full signal but everything was delayed.

I have similar issue to receive delayed messages after the latest Open Beta 12. Stock message app on unrooted 6T.

Hello,
So the problem comes from the fact my phone is rooted? Yesterday it was impossible to take a video correctly for example my phone was shutting of every 30 seconds, and the mobile phone network bar disappeared, then came back and so on, like if I was losing the network every 30 seconds. I'll try to do a video of this

This is not normal. I've been rooted for months and do not have these problems. There is something else wrong

Just being rooted wouldn't be the issue. Sometimes it's honestly as simple as resetting your network settings. As for camera issues have you modified your camera in any way, possibly added a magisk module or something that isn't compatible with our phones, outdated modules can sometimes cause issues as well. It's hard to pinpoint but rooting isn't the issue as these phones were designed for rooting. It's something else entirely. You said your on T-Mobile, was it branded T-Mobile? They like to put their own bloated apps on phones that could probably cause issues too. This is why I went straight to the actual company. You get more up to date and their warranties better than tmobiles. Without knowing what's on your phone I can just speculate. But no just rooting and unlocking bootloader isn't causing this issue

I bought it from One plus directly, not T mobile. I resetted the network settings a lot of times and it still does the same thing. I noticed it happens more when several applications are opened, like when I watch a youtube video and do something at the same time. But even after closing youtube app and all my other apps, it does the same thing. On magisk I have: Busybox for Android, Energized protection, Google product sans, IOS 12.1 emoji, systemless hosts, viper4android, youtubevanced.

I've noticed that being on WiFi causes phone network issues (e.g., phone calls going straight to voicemail, text messages being delayed). This is with WiFi calling disabled, and a non-rooted phone. Really not sure what's going on here, especially because when it happens, my network signal is just fine. But if I disable WiFi, the delayed texts come in immediately. Super annoying.
This is on T-Mobile, latest beta (I think version 11).
