[Q] [Help] Has anyone met such auto-restart issue on Omnia7?

I met the auto restart issue by several times on my Omnia7.
It occures sometime on IE and marketplace data loading. When the IE / Marketplace is getting data from web through Wifi / 3G, it hangs for about 2-3 second and then the phone restart / reboot automatically. It's much easier to happen when loading a large size web page in IE.
Does anyone have met this kind of issue or know the reason?
Thanks.

Thanks for reply. The issue is it restart the phone automatically, not only the application itself.

remove battery

No anyone other meets this issue? Then I doubt it's not because of software but hardware

Turn phone off and remove battery for 10s min. Then start the phone again. If problems continue and you have a Samsung or carrier support center near you, make them update the firmware to a new one and see if problem is solved.

Thanks for help. It doen't happen so frequently. I've done phone reset and also flashed it into another rom. But the issue is still there.
I've just update it into the new 7008 OS by Zune software yesterday. Hope it could be resolved.

It happened to me once. Just once. FYI, been using this phone for 2 months and it only happened once

Happens to me sometimes on HD7. Not on the Omnia 7 though

It seems not only IE and market place. I met it again yesterday that one app which uses Map control made it crash with Wifi connection. I think that might be because of some data receiving problem on Wifi part.

I've had this happen once since I had the phone in November last year. It was in marketplace, the phone froze and then rebooted itself. This was last week.
I have not installed the update. Like I say this is the first time it's ever happened.

It is most definitely firmware related.
I sent my phone to repair (SIM card reader broken), and they flashed an unbranded rom on it(that was an unexpected extra) and the JK1 firmware. Now I don't have random restarts anymore.

It happened to me twice Yesterday. My omnia runs the 7008 firmware.
I changed my SIM card and hope the problem will no longer appear.
Do you solve this problem in the meantime?

Your comment makes me believe the problem is SIM-card related. I've heard of phones randomly rebooting by faulty SIM-cards. I know HTC's problem is mostly mainboard related. Sure do hope it's not a hardware failure. I'll try it for another week or so. If it happens again I'll send it for repair.

I have the same problem. I just have a new Omnia 7 from repair, and the new one already rebbot 3 times since yesterday!
Any idea why?

Is your omnia 7 warm? If it's warm, you must to change your CPU, your cpu is overheat.
Problem will go away. It costs about $75.

I suffer reboots
I suffer from the rebooting problem, sometimes randomly reboots when accessing data (3G also). Well, I believe this is when it happens as it happens a lot!
There have been occasions where the phone gets stuck rebooting and sits with the Samsung Omnia 7 splash screen for ages before powering down; or reboots in a loop.
I tried updating the bootloader with Samsungs tool (after putting the phone in download mode), I've since tried flashing different ROMs and non of them have fixed it.
Currently using:
Phone: I8700XXKB3
PDA:I8700XXKB2
CSC:I8700XENJK1
OS Version 7392
It's so frustrating, it's been to a Samsung 'repair centre' but they just seemed to factory reset it and claimed it was fixed. Next step is send it back to Samsung and hope they fix or replace it for me.
VERY annoying as I cannot use the phone at times when I'm out which is worrying.

I was listening to music, browsing facebook and doing several thing at once with case cover on; then i took off phone from cover and it was very hot, so i supposed it was a over heat problem...
it just happened once for me

I tested this with the SIM in my phone and the SIM out of my phone. It made no difference - I received random restarts in both cases.
It's definitely software related though, as I never received these crashes before upgrading to Mango RTM. Not saying it is Mango, but maybe something to do with the firmware installed in the process of upgrading?
I am really hoping that the official Samsung upgrade to Mango includes new firmware and that it fixes the issue. If not I'm getting rid of this phone, I don't want a phone with features I can't even use. I got a full phone crash the other day when just trying to view a map.

I have it also it only happens when I search websites with the Bing search button. I search websites that I already know that exist and even trough the phone is connected (most of time via Wifi) it shows no results and then restarts. I think any ROM replacement will fix it as I have tried them all without success.
Definetly the issue has something to do with Bing services

Hi I had some random reboots but just a few ones like maybe 3 or 4 in 6 months but since I installed Mango beta, it starts to reboot randomly like you on IE or marketplace but removing the battery a few minutes used to fix this.
I thought it was firmware problem so I flashed it with a lot of different firmwares ( now i have KC1 ) but It didn't solve the problem even worst, now my Omnia 7 is stuck in a boot loop.
I suceeded to make it work for a few hours playing games or using bing maps after puting the phone in the fridge for a few minutes. Now the phone wont charge because of bootlooping so even the "fridge fix" doesn't work. Maybe I will try to change the battery but here in france it's really hard to find Omnia 7 stuffs. Maybe its firmware problem because my phone dont look so hot but it acts like overheat problem. Maybe trying to calibrate the temperature sensor by diagnosis if someone knows how to. I'm ok to try it =)
If someone can give us the normal temperature of their omnia 7 maybe we can compare and try to find the solution.
Thanks for reading my bad english ! =D

Missing calls with official 2.3.5

Hello everyone;
I flashed the latest official 2.3.5 last night. Missed three calls afterwards, as if I was not connected to GSM network. I was at home and signal was stable as usual. Anyone else noted unusual GSM behaviour?
Cheers
----------------------------------------
UPDATE: In order to better understand this issue, it could be interesting to know which service providers are being used; in my case, TMN in Portugal.
One week before flashing this ROM, I started using 3G, so I'm not sure if these missing calls are as result of the ROM change. I'm going to switch back to 2G for daily use and see how it goes.

Yes, if you search you will find other users with the same problem.
happens also with the other beta roms.
Sent from my U8800 using XDA App

It happens to me too unfortunately.. can't tell the reason why. GSM status seems ok.

I confirm this missing call issue.
People when ring me the first time they go straight to voicemail and only get connection on second try.
I think the only way to solve it is Huawei but there is not point of trying to speak to them and they just won't listen for what people say to them.

I can confirm this is happening to me too....after reporting all was well this was one of the things I didn't test out.
Weird thing is that I called my mobile from home and both went straight to voicemail...

yep.
but if you immediatly make a 2nd attempt you get connection

OK try this...
Turn off phone... re move battery and sim card.
Replace battery and start phone without sim card and boot up.
Unlock phone and open any app (doesn't matter just do something)
Turn off, remove battery, replace sim.... boot up again.
Just called from my wifes mobile phone and my phone rang OK.... will test further but that seems to have done the trick for now.

I got the same problem and so far nothing i did solve it... Just missing reinstall the rom again and see if wasnt any bug i got while installing... I don't see too many ppl with the same problem and i don't belive huawei had so many diferent hardwares in a single mobile phone model according with all the different ppl have with different phones.

I also have this problem with the new firmware. My phone doesn't connect to the network upon powering on.
I have to manually connect it, by going into the Mobile networks settings. Once i'm in that menu, it connects.

druida_69,
I can confirm that does not happens every time, I tested from other phone I only on the sixth call I got the ring... Worst, during this time I made a call without problems.
The question is on reception...
Sent from my U8800 using XDA App

this issue is killing me.
when I have the device disconnected or in a cal, when someone try to ring me and can't I always receive a message informing that the xxxx number tried to ring you at that time bla bla bla.

no calls
The same thing happened to me... also tried many things without success... downgraded to 2.2.2 (B138) problem solved...
I'm getting tired of huawei's poor support and buggy updates!!!

To be honest i don't know if this start to happen after or before installing geno‘s OC Kernel.
I can confirm that this happens when the phone stays for a long time inactive. Try not playing with you're phone gore 20 minutes or so and then try to ring youselves.
Its like if the phone entering in a zen deep sleep....

Same here
Started after updating to 2.3.5, anyone tried the updated 2.3.5 from Huawei? it removes the pink screen I heard, but maybe it fixes this issue

F****** Huawei. Just realised that I have this bug too with latest 2.3.5 release... I think that it's data dependent. If you turn them off it connects ok...

I didn't realize until I read this thread, but I have the same problem!
I'm over it, I'm going back to Oxygen until I can buy a new phone, and will probably never buy huawei again.

I had this problem initially but since I booted up without sim card and boot up again with it in hasn't been a problem...I've had to test this on a few different phones & reboots now and everything is fine....

[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.

N910C emergency calls only... again

Hey, so 9 months ago I had the same issue that probably has a different cause now. Back then, I used to get the emergency calls only error and my efs was corrupted because of flashing CM13). I fixed it by restoring the nv_data backup I took. Now, I get the same **** all over again, except this time; I DID ABSOLUTELY NOTHING. NADA. ZILCH. The phone went off on it's own, along with the very ability that classified it as a phone.
The IMEI number hasn't changed at all. I mean why would it, I did nothing that could cause this. Flashing new roms doesn't fix this, and neither does that mystical voodoo **** (reinserting the sim-card so many times that you see gold contacts in your sleep). Oh, and I lost the SD card with the original backups on it.
Whenever I try to connect to a carrier by the network operators screen, it just times out. So is there anyway I can fix this? Or at least PINPOINT the problem so I can fix it?
Oh, and there's a thing going with the IR blaster too. It's dead. How would I go about changing the blaster out? It doesn't seem openable like the S4 I had was (metal frame).

Bump

bump once again

Oh come on, nobody has a clue?

Hi @Peontikos_Desmos, actually I have the same problem as you. I have a Korean note 4 n916k and since 1 month I have this strange problem too. I tried everything I know, reflashing original roms from Samsung(android 5.0.1, 5.1.1, 6.0.1), many custom roms ..., ... No way, no solution. The only thing that I tried to make my phone working as phone is just put the network mode in setting to 2G, not 3G, nor 4G, just 2G. With 2G only as network mode, the emergency calls only disappeared BUT now I can't connect to 3G and 4G anymore. Please please help us guys.

Factory t-mobile S7e losing mobile network connectivity

so this is the second S7e and second SIM that I have been having this issue with. The phone will lose connection to the mobile network and the ONLY way to recover is to reboot phone. Reset Network Settings doesn't do anything. Toggle airplane mode doesn't do anything. Search for Network Operators doesn't do anything. I have a third phone on the way - but has anyone around here heard of or experienced similar? Am I missing something that I should be doing to correct this?
Thanks in advance

I too have this problem. Got a replacement refurbished phone under warranty and the phone has this problem

Did you pay the $20? I didnt want to pay the 20 so i sent the device to samsung. Should get it back friday or monday. The issue is definitely phone related. Im using a verizon s7 now and no issues like that arose. I even tried new sim.. My father is having same issue t-mobile s7 edge

Yes i had to pay 20. And it's disappointing I am having this issue with the replacement phone. I am having this problem on the U firmware as well.

I've suffered the same issue from time-to-time and just do a restart....annoying as hell to be honest

Are you guys always in the same location when this is happening or is it just whenever and wherever? Or is it happening a one certain place where cell signal isn't that great? I had this same issue BUT only in my house so I had to get a network range extender from t-mobile to use at home.

This happens to me all the time. It's so annoying. At work, in the car, at home--it doesn't matter where I am. Have reset firmware multiple times and even rolled back once too. I think it has to do with the latest software because I never had this issue before the Fall/Winter. Hopefully Nougat fixes this!

I am having the same problem, this will be my 3rd phone 4th sim. I wish I knew how to fix it

I would try flashing different radios/modems, its worth a shot. Maybe try flashing the "U" firmware radios.

Nougat will fix it
My wife and I had the same issue on our tmobile s7 edge ... we got the 7.0 beta and now the issue is gone .... I bet it's radio and software related ... 7.0 will be out by the end of the month hope that helps...

I had this issue with my phone, and it was a huge pain. The biggest concern: I didn't know when my phone was off network (voice, data, etc.). The fix, for me, was simple: a new SIM card.

You may have an issue from a rejected permission on an app.
Had the same issue before but I did a hard reset and realised that I changed permissions on an app that wasn't written for 6.1.

I hope so! Been waiting for that before I try anything drastic, even though this issue is a huge pain in the ass. I'm glad others have come out of hiding to express their concerns with it as well. I thought I was the only one for the longest time having this issue.

Many of us have tried new SIM cards, but it's worth a shot if it's still not working consistently after Nougat is released.

My and my friend's phones are both running pure 100% OEM Tmo stock without any apps disabled or touched at all and we have this issue and have done multiple resets. Pretty sure it's an actual hardware defect, or hopefully just a software one with the modem/radio.

I sent mine to samsung and the things they replaced is the Coaxle cable "antenna" replaced 3 of them. I have been using the s7 from verizon on the U firmware so havent seen if it is fixed.

I received a refurb. Other than this problem, the phone is alright. I noticed this problem on receiving the phone it was running on T firmware. Then I switched to U firmware and radio but no difference. I called customer support yesterday, they said to go to a retail store to get the phone replaced. My worry is going through this process again and if I receive a bad device again what to do? After all refurb phones are like playing Russian roulette!

I just had this start happening on mine... I really wish they would release nougat already. It is ridiculous they won't post an Odin flashable version of the release candidate if it does indeed fix the issue.
I also think its a specific tower configuration that is causing the issue that the radio can not understand. (Maybe 3xCA). Its happening in the same areas every time.

I just started having this problem in the past month. All at once I've been getting BT sometimes turning off, mobile networks failing to reconnect after I visit a no/low signal area (such as after a plane trip when the phone was in airplane mode). I've also seen wifi mode fight my attempts to turn it back on sometimes - toggling itself on and off a couple of times per second until I poke at enough settings to stop it. When BT turns itself off I have trouble turning it back on, sometimes it just goes back on, sometimes it refuses after a number of tries and if I wait an hour it goes back on just fine.
The folks at a BB Samsung kiosk said they could reflash it if I wanted to go that route, but that the nougat release would be out soon so it might be better to just wait for that. Has anyone had a Samsung rep re-image their phone to try to solve this?

If you were able to fix without a reboot you didn't have the same issue as this.

I guess I wasn't clear about that as I have several problems that are probably related, but behave a little differently.
BT dropping - can usually turn it back on, but sometimes it refuses. Usually don't need to reboot to fix this.
Wifi dropping - often have trouble turning it back on and have seen the widget toggle off and on repeatedly by itself. Sometimes have to reboot to fix that.
Mobile Network data (and voice sometimes) dropping - usually have to reboot. I think I may have recovered that once without a reboot, but the other few times it's happened in the past month since it started I have rebooted and that fixed it in all but one of the reboots - one time I rebooted and still had to fiddle with it a bit after the reboot before it came back. That may have been because I played too much with the network settings before the reboot and so had to undo that damage after the reboot. But, definitely rebooting is a fairly reliable step in fixing this problem.
All 3 started happening around the same time which is why I thought it was a software issue (I remember a small update a little over a month ago, but forget the details of it). It's nice to hear that others also have the mobile network problem, but if that is isolated in those cases then maybe I'm not seeing exactly the same problem. But, it is clear that rebooting is almost always required to get my mobile network data back so that again suggests that at least that part is the same as what this thread is discussing.
In looking at the T-Mobile updates page for the S7 Edge I see that the version I have (G935TUVU4APK1) was updated in early November - which tracks when I started having problems, and it includes a fix for "Domestic data roaming improvements", which definitely sounds like they may have played with the radios.
I am so ready for the Nougat update...
