Data Connection Problems (I9500) PLEASE HELPP!!! - Galaxy S 4 Q&A, Help & Troubleshooting

Hey guys!!
I am facing a problem here... my phone loses connectivity to data services once on sleep mode and applications like whatsapp only respond when I open the application. Basically push service seems to be stuck.. I tried everything.. switching ROMS, switching Kernels... and switching Basebands... but in vain!!! Ironically everything works fine on wi-fi & i get push messages swiftly.
I strongly feel that this could be a baseband issue and as you all know we cant downgrade our baseband anymore.. I am on UBUBMH1 modem.. iI think so because when i was XXXMEA then I wasn't facing any such problems related to connectivity..can anyone suggest any resolution of wither how can I downgrade my baseband or what can I do to sort this out..

no help???

[Q] HTC data connection freezing.

Hello all,
Not sure if anyone else is having this problem.
First of all, better to mention what my Aria is running on:
Stock ROM unrooted. Updated to Froyo from HTC via FOTA. I'm not located in the US therefore my phone isn't under AT&T which many here are. My ROM is strictly HTC's Asia's ROM.
Now I don't have much in a way of problems with my phone, its just odd to me that every once in a while (around once every week or so) I need to reboot my phone. This is because for some strange reason, my phone won't connect to the data network (3G) or it shows that it is connected but no data activity (even after I've instructed the phone to sync all information, i.e. weather, emails, etc). I've tried switching on/off the data network connection and also have tried switching between airplane modes on/off (in hopes to reset something) but nothing works.
I'm not sure if this is an inherent problem to the Aria's 2.2 update or if there is something wrong with my carrier, however the problem is ALWAYS FIXED right after a fresh reboot.
Anyone have any thoughts on this?

Phone information. Set preferred network.
Try switching between the different options.
Sent from my HTC Liberty using XDA App
Thanks for the hint thinkhope. I'll try your suggestion. May I ask what you think the problem may be?
Update: I tried it for a couple of days and I still get the same problem. I tried switching between preferred networks but the problem persists. Quick reboot and once again, fixed.
I also have this same problem, stock/custom ROM no matter which ROM the problem is still there, up to a point that made me wanna smash my phone on the ground. I tried to use my SIM card on my wife's SGS and seems like no such problems faced. Is this a common problem for HTC phones?

[Q] Galaxy s4 wifi stuck dim green problem

Hi there, i've a galaxy s4 gt-i9505 since dec 2013 and i've been experiencing the wifi button stuck in dim green (wifi stuck with that activating ... Message and not working) and not working since ive bought it. It came originally with the android 4.3 stock rom. First i thought it could be a hardware problem but when i reset the phone to it factory settings wifi starts to work again. Ive noticed that if i stay with only one wifi network registred (the one i use to reconfig the phone during the first reset) the wifi works fine, but when i try to connect to a second wifi (any router) the problem arises and the only solution is to reset to factory settings again.
Ive read tons of people complaining about this problem but ive never heard of this second wifi netwrok issue... I dont know wether android loads a different config or modem driver for the first wifi network registred during the first boot but the problem only comes after i try to register a second one. Ive tried all wifi config like keep wifi on allways etc but nothing seems to solve the problem. Ive also tried the airplane toggle trick but didnt work. Ive tried other stock roms from other countries like germany dbt but always on android 4.3... Any help is appreciated. Thanks!
Im on i9505vjuemke now...

[Q] Note4 loosing data connection

Dear Friends,
has some who owned note 4 faced a continuous loosing data connection?
I have been facing this issue for the passed one week till now, I have tried to format the device but the problem is still there, I have not done anything to the device.
I called my ISP and they said that there is no problem with your sim card.
please advise if anyone of you had similar issue.
thanks

I've just experienced this today on my 1 day old N910C, I'm on 4G and suddenly earlier today my 4G mobile data indicator disappeared but it still showing the usual signal bars. Tested browsing, no mobile data it said. Tried putting it to Airplane mode then back to normal, didn't bring mobile data back. Rebooted it, then it's working again.
Not yet to see this problem but my friend's Note 4 had this problem. In the end he brought it to the service center and they replace the mainboard. Still wait and see if it fixes the problem.
it happened me before on other samsung devices too. generally an update fixes it but could be hardware problem too.
Hopefully its software related ive seen a slew of note 4s have this issue both variants included.. its annoying to say the least
Hi, I just got my phone, may i know whether you guys have resolved the issues?? i need to turn the flight mode on and off a few times to get the data connection back online
I sent back to Samsung services center, it seems that they said they reprogram the software. Will observe and see how it goes.
Mines all good now few updates and new provider all good ?
Hi guys, I've experienced the same issue, the mobile data connection suddenly drops (H+ icon doesn't disappear but the download arrow is off, meaning that there's no inbound traffic) and the only way to have the connection back is to to disable mobile data and than reactivate it. I've updated my phone, I even tried to install firmwares of other countries (different csc) and to change carrier but I haven't solved the problem (same situation on my friend's N4).
Hi
i had a problem with wifi. weak or no connection.
100% solution for my note:
go to settings=>location=>use GPS ONLY.
perhaps it solves also your problem...
Hello all! Just faced the same problem! Losing internet connection. Did anyone find a solution?
Note 4
Yes this is BS. If I go to a place with no data service, then travel back to a place with data service, I have to first disable then re-enable the "Mobile Data" toggle in the settings. It's such BS that this is happening. My note 3 NEVER has this problem. Starting to dislike Samsung's buggy releases.
Same issues..

[Q] Samsung G900F WiFi Problem all stock

I recently bought Samsung S5 G900F from a friend which updated it to latest lolipop 5.0 software, and after that wifi stoped working.
It was never rooted or etc. When i try to turn on wi fi i press button for turning on freezes and it doesn't show any wifi network. By my friends words it started after updating to lolipop. First i downloaded and flashed two 4.4.2 from sammobile and i there's no difference at all.... Second thing i found thread with latest modem on xda and nothing at all.
The only thing that helps for short while is from unkown reasons when i switch SIM cards it starts working but speeds are 200,300kb/s and signal is very low. And from some secret code went to wifi settings and turned off battery saving mode, it helped to now more often it works but for short while and slow speeds.
I don't have any ideas, what to do with it all sings show that it is software issue. Thanks in advance on replies
This erro my phone not my eny solution.?

Help - Connection problem/lag after upgrading Android 8.0

Hello everyone. I have a samsung galaxy s7 edge (SM G935F) and i recently received the android 8.0.0 from samsung. Downloaded and installed directly via the cellphone.
But after updating i am getting this internet/connection drop issues a lot.
Now a lot of times when im connected in wifi or using the 4g mobile internet, im getting a lot of internet lag/drops. Example: at whatsapp, when i sens a message, the clock appears and only after a little rhe time the message is send.
Example 2: at facebook, somerimes it lags and takes too long to load the content (same happening in instagram). Or at clash of clans, it is showing that symbol of internet issue.
Besides those internet bugs/lags, the android 8.0.0 is ok.
I already did a factory reset yesterday via the phone, and saved the files with smart switch. But the problem persists. I also checked and my wifi internet and my mobile internet are ok.
Does anyone knows how to fix this issue? Is there a newer version of the ROM, maybe? Or if not, is ir possible to downgrade to android 7 again (really wouldnt like this option but....)?
If anyone could help that would be great. But for the record:im really newbie at android stuffs....if you can help, please could you explain step by step?
Thanks everyone
Another bug i am noticing: besides the internet crash/drop (wifi and 4g), i've noticed that it is taking too long to charge (around 3h...3:30h), even with fast charge.
Does anyone knows how to fix those bugs, or anyone is having those issues ?
Can i flash again the BTU ROM of android 8.0 from UK, with CSC from android 7.x from Brazil (ZTO)??? I mean, is it compatible?
thanks

Hi,
My S7e has just upgraded to 8.0.0 and is now having the same wifi lag issue. Did you manage to find a fix?
Thanks
Ady
I'm also noticing the same issue with my S7E. I'm on XEU.
Has anyone got the same issues with BTU as I'm considering swapping over?

I fixed the issue on my device. The problem was having power saving mode enabled, I use to run it all the time on nougat and never had an issue. Yet I turned it off and now there's no connection lag what so ever.
I was having the same issue with btu xeu even custom. On Oreo my wifi switch went totally gray and screen pattern unlock would also take 20-25 sec to unlock but then I flashed this kernel and everything works like a charm.
