Help - Connection problem/lag after upgrading Android 8.0 - Samsung Galaxy S7 Edge Questions and Answers

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 Is there a newer version of the ROM, maybe?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.

[Q] wifi problem solved?

hello there,
this phone is just released in my country. i would like to buy it but i found this video on youtube: http://www.youtube.com/watch?v=ptg6cLdA9OU
is this problem common? is there any software to fix?
this video is too old (the rom is B133), i used both B135 and B136 now, with no Wifi probs at all
that's great. thank you.
I agree. I am also on B136 and no issues at all with wi-fi. Good Luck. I think it is a great phone especially for the price.
B136 is the pre installed ROM?
Or in other words: people that buy the Ideos X5 today will not have any wifi connection problems?
Obviously I can only speak from my experience with my own phone, but it came (3 months ago) preinstalled with B133 and did an update over wifi in the phone's update options and had no problems before or after the update. The update was about 3 weeks ago for me and I have been using the wifi almost every night since I go the phone. I am very happy with it
Can warmly recommend this phone, its great !
The price is nice, the quality is fine and the phone is getting a larger community !
If you find trouble with old firmware always update to the newer ones !
Grab them at Huawei and upgrade your firmware, they have a guide included on each firmware download pack you download.
Agree without doubt. I never experienced wifi connection problem. But only some education institute use PEAP encryption may post a problem with most Android, though not the phone itself .
Sent from my IDEOS X5
unfortunately its the phone thats causing wifi dropouts in my case..
i can connect to my wifi router with my iPhone 3GS, my notebook, my netbook, my NDS, etc.. in fact X5 is the first and only device that has connection problem with my wifi router..
though i like this phone very much, i can honestly say that wifi problem does exist, at least in certain instances including mine..
So it has been established that this phone sometimes has wifi issues. The question is; can they be solved? and how? anyone got any experience in that area?
I'm on B136 and WiFi is still broken. B136 seems to have made Wifi connections a little bit more reliable, but it still drops out pretty regularly, usually when I try to update more than one app at a time from the Market. In the middle of the downloads it stops because the WiFi has become disabled and has to be restarted again.
It's less of a problem when there's only one update to download, but if there's two or more it happens quite frequently. It also still sometimes happens (though perhaps less frequently than before B136 was released) while it's not downloading anything, just sleeping (I have it set to not disconnect when asleep) or awake and connected to my WiFi network.
The unreliable WiFi connections are one of the two worst problems with this phone (the other one is the wildly variable battery life).
Nobody has a definate solution to this problem?
Is it part of your insurance btw? it is clearly malfunctioning and perhaps should be fixed by the company you bought it from...
i am using genokolar's b137 and wifi is fine ( i had problems before with stock 135).

Where are you download this custom rom? I only find one V8 in chinese forum. Is this, you'r talking about? Is this multilangual?
yep this is it!
every android version is multilingual!
thats his latest version:
http://bbs.goapk.com/thread-3177723-1-1.html
also use the google apps (GMS) from here:
http://bbs.goapk.com/thread-2875088-1-1.html
be sure to have this installed before doing anything:
http://forum.xda-developers.com/showthread.php?t=1130524
if you find it hard to download them from there i have uploaded them here:
http://www.megaupload.com/?d=IMZBGHIA (use the gapps that are inside this rar)
http://www.megaupload.com/?d=3DOP0APD (use this rom)
i have removed some apps he put in there (like nofrills[something like set cpu], a chinese market etc) to make it a total stock rom. just be sure the 1st app you install is Superuser.
I did some tuning to my wifi configuration file and that's all I did to solve connection problems. Just take a look through my thread in the general section with subject title "Wifi Client Tuning ... Solve Connection Problem "

Telus Desire HD OTA Gingerbread - New Radio

Hello all, this was brought to my attention today, courtesy of my news feed from mobile syrup.
Today Telus is pushing out an OTA update to Gingerbread, and according to the picture in the link, it looks like it has a new radio with it too. I have no clue about how to get a hold of this, but I thought I would pass on the information to the folks here.

I notice my weather now updates to my current location,other than that,I'm still playing.
I posted some information in the HTC Desire HD radio thread.
http://forum.xda-developers.com/showpost.php?p=15005471&postcount=1619
So far here is what i found after update
Quadrant benchmark is max at 1580
Program opens a bit faster
HTC Message widget no longer have any choice on which sms program to open from
much faster on phone reboot
So is this Telus GB rootable?
Is anybody else having horrible 3G data issues with this update? Whenever I'm not connected to Wifi and attempt to use data my phone reboots. It has made my phone completely unusable. So far I haven't heard of anybody else with my issue though....
It also does not seem rootable. In an effort to prevent having to take my phone in to Telus I tried rooting and failed.

I've been having issues where it won't connect to mobile network .When I try to do it manually it tells me my SIM won't work with Telus,but restarting the phone fixes the issue,still very annoying.
That's a weird one. Mine's even worse though. If I leave my phone in my pocket it restarts about once every minute or two.

[Q] Mobile data problem

I've got some problems with mobile data on my Note 4. I've bought unbranded phone in shop unrelated to any mobile provider. It's Snapdragon version (N910F).
I've got prepaid service, without LTE available (if that's important). The problem is that every now and then mobile data simply stops. There is still H or H+ sign in notification bar, and upload arrow blinks. but when i try to open web page or send message through viber, wattsup it acts like there is no network. Then i have to wait for about 30 seconds or manually turn mobile data off and then on again for internet to start working again.
I've tried changing APN settings, changing network type, but the problem is still there.
I've read some similar issues with Note 3 and SGS5 users, and some problems with modem versions, but i couldn't find anything from note 4 users
And this problem is very frustrating on phone like Note 4
Is there anything else i could try?
Mate i have exact same problem
I don't know if this is relevant, if your apn settings has a proxy and port values, try to delete it and let the proxy and port be blank. I had issues previously with data getting stuck while using proxy setting.

I also loose data signal and on calls people cant hear me properly.. doesny always happen. Ill try thanks
Also experiencing this with Tmobile UK.
Also have this exact same problem with the unbranded SM-N910H, H+ but no internet all of a sudden. I also sometimes lose the whole signal (Emergency Calls Only) so I have to reboot or turn airplane mode off and on to get it working again. I asked some people and they told me it's a coverage problem with the network provider. IDK if it's true.
No ahmadmob its the phone although i have n910u i have exact same problems as u!! I thinks its modem hopefully gets solved soon im in Australia using prepaid only 3g/h+

Glad it's not a carrier specific issue.
Guess I'll wait for an official fix or for other radios to become available.
I rang samsung australia few weeks ago and they had no idea than again when do they ever!? Lol so looks like we will have to wait buddy
Some common suggestions:
1- Swap the SIM card into another phone to see if the problem persists?
2- If the problem is due to Note 4, you may need to update your firmware/baseband to the latest one (if one is available, or you have to wait until Samsung release it), or try another firmware (from another model) or custom ROM.
Tried already mate sims fine updated reflashed stock rom and still same problem.. hopedully update comes soon
I just tried sim card from another carrier, and for now, everything looks fine.
I'll go ask for a new sim from my carrier, or switch my number to another one.
Sorry for digging, didn't want to make a new topic.
I'm here with the same problem. Did any of you find solution for it (other than switching to different carrier). I'm on Play in Poland and i find mobile data problematic mostly in roaming (free roaming with every carrier in Poland). For example on t-mobile or plus i find my up arrow constatnly blinking and H switching to H+ and again. Problem is even worse with 2 or less signal bars. I'm thinking of changing sim cars to new one, but on my note 2 everything works perfectly fine.
I thought I noticed a slight improvement after the final KitKat update, may have been a placebo effect though.
In general it's still bad, much worse than my HTC M7, same network, same location etc. It seems to be particularly bad when travelling at speed e.g. on the train I get full bars but only 1 arrow flickering.
Upgraded to Lollipop a couple of days ago and finally rooted, doubt this will make a difference but will be able to report during my commute tomorrow.
In summary: The HSDPA modem on my phone is rubbish.
P.S. Previous phones I've owned came with options for different modems, I'd often flash these to improve performance, where are they for the Note 4?
I think they're not available yet, at least on lollipop...
Mine is completely fixed after a few updates i get 4g+ here excellent reception

Could tell more how did you fix your problem?
All fixed!
I can confirm that after the lollipop 5.0.1 update on my SM-N910H all my mobile data problems/mobile network drop outs are solved!. 3 days without any problems now.
Edit: maybe it had something to do with Radio and it got fixed after it got updated along with the lollipop update package?
Guys, here in my country Bulgaria, many of us owners of SGN4 have the same issue and wilth Lollipop also. I have noticed that with KitKat the problem was more frequent than Lollipop but it is still there. We have tried Polish Lollipop and now the official Bulgarian Lollipop but the problem still exists. I hope somebody will tell me which ROM you have installed (oficial) so I could share it with my fellow citizens. Thank!

[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.?

Samsung Galaxy J5 crashes when connecting to certain Wifi...

Hello all,
I'm experiencing a strange phenomenon with my Samsung Galaxy J5 (model number SM-J500FN, running Android 6.0.1) and was hoping someone might be able to help!
It works fine most of the time, but stutters and crashes whenever it's connected to one certain free Wifi network. This "guest" network is provided by our local council and is accessible in libraries/leisure centres/schools etc. Other friends with Android phones can use this free network with absolutely no issues, but my J5 slows to a crawl soon after connecting, and is soon unusable. It doesn't even reboot easily, and when it does (eventually), and I reconnect to the network, the exact same thing happens again. The only error message I've seen pop up during the stuttering procedure is "Touchwiz home has stopped working".
I stress again that my phone experiences no issues whatsoever when connecting to *any other network* apart from this one, free Wifi.
Does anyone have any idea why this is happening? Or, more importantly, how I can address this issue? (This free, guest network is prevalent all over the area I live in. Sometimes my phone connects to it in my pocket without my knowledge, and it takes 15 minutes to restart my phone and be able to use it again!)
Any advice would be very welcome. Thanks for reading, all the very best.
P.S. I am by no means a phone expert, so it would be hugely appreciated if you could walk me through any potential fixes, I'm not brilliant with jargon... Thanks!

You can do one thing. Download the latest firmware from Sammobile for your model and flash it using Odin. If there is any problem with your firmware then this will fix it. I also had some problems with my phone's firmware so i flashed the latest firmware from Sammobile and everything was fixed. Sometimes there are some problems with the firmware which come by default with the device at the time of purchasing.
