WiFi switching issues since last update - Samsung Galaxy S7 Edge Questions and Answers

G935FD Exynos, stock firmware updated via air.
Now it says Android 7.0 G935FXXU1DQEM, DQG1.
I often face the bug when the phone is expected to automatically connect to my home or job's WiFi, but in 50% cases it doesn't. When examined i found out that sometimes SSID list is outdated and stuck, and it won't refresh as I tap on refresh button. The only solution yet is to turn wifi off and then on. After such procedure the phone behaves as expected for some period of time.
Anybody has a remedy for this bug? Forgive me ROM makers and fans, nevertheless I won't take an advice to flash a custom firmware. Thanks.

Yes , since july update there are wifi issues that i am suffering from , and august update didnt solved either , the only way would be download stock firmware from may patch from sammobile and flash via odin or wait for next update to solve these issues

Wifi issue on Galaxy S4 I9505

Hi all,
Ever since updating to the latest MGA via OTA firmware nearly 2 weeks ago the Wifi has been causing me a lot of issues. The following evening after updating the firmware, the wifi just randomly turned itself off and would refuse to turn on again. When I attempted to turn it back on via the widget, it would go grey as it's attempting to turn on but then it would just stay at that and it will not turn on at all. After a few minutes it will either go back to being completely turned off or the phone would just reboot itself.
Now, I have tried several things to rectify the problem i.e. applying the MGA wifi fix, factory restoring the phone via the settings and also in Kies, downgrading back down to the MEA firmware, re-flashing the stock MGA firmware via Odin and re-flashing both the MEA & MGA modems seperately - all to no sucess!
At the same time while all this is going on, the phone itself will sometimes randomly reboot itself when attempting to turn on the wifi or even in the rare case when the wifi does turn on and it will work for 5 or so minutes - the phone will reboot itself again while trying to simultaneously update various apps through the play store.
Lastly, the phone has already been sent back to Samsung a few days ago regarding this issue and the phone was returned back to me yesterday with Samsung apparently stating that they had diagnosed and found an issue with the phone (even though they could not tell me what??) and that they had sucessfully repaired it. Upon turning the phone back on going through setting up the phone again, I come to the wifi connection and guess what... it doesn't turn on. Yep that's right, I'm still stuck with the same problem!
I got straight onto Samsung on the phone and complained about this as I'm not happy at all, and they have agreed to have the phone back in for another repair and apparently something will be done properly this time.
It's not good enough though, to me all it looks like that Samsung have done their end on the original repair is re-flash it with the MGA firmware once again, shove it back in the box back to me and hope for the best. Even the Samsung agent on the phone yesterday could not tell me exactly how they apparently repaired the phone as there was not anything on the repair report what so ever, unbelievable!
Anyway, do any of you guys have any ideas with what else I can do my end to try and rectify the problem? To me though, this sounds like a physical hardware fault that only Samsung themselves can sort out...
Thanks - Liam

Well I have only had this problem with rooting phones etc... to me this happened with so many ROMs I tried. Even certain stock roms. I am not sure fully how I fixed it, but I know now I am running the OMEGA rom and this seemed to have worked for me so possible to try that? Just an option

When I first downgraded back down to the MEA firmware that I was linked to from another forum, I discovered straight after flashing that it was a pre-rooted ROM and the wifi still would not turn on then.
The phone has been sent back to Samsung again today for another repair but last night as a last ditched attempt, I downloaded & flashed the stock XXUAMDM firmware from April and the wifi still refused to turn on.
I'm still convinced that the problem itself is hardware related rather than software based going by that the problem is still present regardless of what ROM I'm on, it's just a case of trying to get Samsung to see that. I can understand now why that Samsung the first time round probably only did a fresh re-flash of the MGA firmware instead of going ahead and taking the phone apart/replacing parts as I imagine it's very labour intensive/standard procedure and not only that - the S4's mainboard (from what I've seen the wifi module is part of the mainboard) retails at over £200 which is a hefty repair cost on their part.

It is some sort of permissions issue.
If you do chmod 777 on /dev/*, /system/etc/wifi/* it should be working.
The only thing I haven't figured out is why
And it has to be done again after rebooting the phone, wich makes me sad.....
How I fixed my WiFi and sound problems after updating to latest firmware over
Hi there. (Sorry for any mistake about my English). By the way, I'm newbie on Android.
After freaking out about my WiFi problem, i didn't even care about the others problems like the sound, and I don't know if there were or if there is still some, but WiFi and sound got fixed.
After a lot of research on Google and XDA I came to the conclusion that if I could just re-install the firmware, I had
1- I Download the same firmware you are on (i guess it safer this way) I got the same (I9505VJUEMKE) that had caused the problem when was update trough Kies.
GT-I9505_PDA_I9505VJUEMKE_4.3
Changelist: 2210919
Build date: Wed, 27 Nov 2013
CSC: I9505ZTOEMKE_ZTO_Brazil
MODEM: I9505VJUEMKE
Gdrive: (créditos ao +Alexandre Affonso - Vlw)
Two links for download this firmware. (really fast download since its on gdrive)
goo.gl / UrZWAE .
goo.gl / omJC9e  "
2- Unpack the Zip File
3- Putt the phone in "Download Mode"
4- Open Odin 3.07 and Connected the cable. (check if Odin linked a port to your phone, i didnt get any color change, just the COM Port number and the "added" mentioned on Odin)
5- Load the firmware on "PDA", wait a few seconds till Odin load it.
6- Click Start and wait the whole process. Don't disconnect the cable until Odin says that it was Successfully.
Finished!
After all I did the root with Odin + CF Auto Root + Supersu and So far everything is fine and better than before.
Hope I can help few of you guys.
Thanks.

Galaxy A5 2016 / Restart on its own

Hello,
My girlfriend bought new Galaxy A5 2016 (gold) on 15/03. Already while I was completing some settings (Google acc / Sams acc "in" and install of such mere apps as viber, skype, facebook..) the phone restarted on its own twice, without any logical explanation (no significant load, no root, since the divice was almost stock).
This bug has occured while this week two or three times a day. Unfo I cannot associate it with any app or particular action. The phone reboots even in sleep mode or when screen is active.
It doesn't look like hardware deficiency. I tried to delete Google Play Services updates (suggested by local Sams support), hardreset and etc., however - no success. The phone continues to restart its own
Have no idea what to do Can you help me?
best regards

Are you use memory card/sd card? Try to remove that...
It happened to me the same thing on my old Desire S... The battery were not firmly pushed in its location... So, you could verify that!

Reflash stock rom...
I don't have this issue at all , try a factory reset or flash a stock rom.
Hi,
I've bought a A5 2016 in February (Rom stock, No root, dev options unmasked) - Since then, I've Had 3 power off on its own. I've followed forums and wiped my cache. But this morning I had my phone restart on its own.
I'm quite mad at Samsung for now.
Maybe try calling samsung support?
I have had this problem with my A5 too. Whenever the device updates some app, it re starts.
What exactly occurs during the restart? Does the phone vibrate and show "samsung galaxy a5 (6) powered by android" or does it simply play the boot animation without audio.
If the second option is happening with you., then I suggest you re flash the stock Rom. You can get the stock rom from you mobile or San mobile.
I have the A5(2016) from 2/3 weeks but I never had this problem. If you have the A510F model you can try the German firmware (A510FXXU2APC4 - (build version LMY47X.A510FXXU2APC4). Flash it via odin and donwload the firmeware from sammobile.com. for odin guide see here http://forum.xda-developers.com/samsung-a-series/help/rom-stock-firmware-samsung-galaxy-a5-t3305863
To Ahmad89:
Thanks for your response. I actually had logo A5-6 powered by android during restart. I remember to have switched on WiFi connection before it restart (i know that updates occurs only when WiFi's on). That may be an explanation. there may may have been an attempt to update. But the "switch off on its own" event seems more annoying. I did remember one time my phone went off when charging and at that time i used non official Samsung charger. perhaps it was linked to fast charging and a powerless charger that shuted the phone off. What about the two others occurrences when it went off? (the phone being in stand by mode). I can imagine every scenario but no valid explanation.
To zyxw :
I've had the phone update to XXU2APC4 since 3 hours.
I'll do my best to stay in touch for relevant news.
Thanks.

I had the update by Kies I presume. I did it by updating the phone in settings/software update. I had several times used Odin for my note 3 but for my A5 i didn't want to flash the whole ROM. My country is France. The New baseband is A510FXXU2APC4 and the version Number is LMY47X.A510FXXU2APC4.
At this time no restart or shut off by its own - but too soon to validate.
I will do a wipe cache very soon.
I'll warn you once restart or shut down happen, if so. :fingers-crossed:
We have the same build version so maybe you will not have the problem!
I have PC4 too , no issue so far.

WiFi after update is now broken.

Hello everyone, I'm having a major issue with my phone.
After unninstalling magisk and doing the OTA update of february, my phone won't "switch" on the Wi-Fi. You can press the button but It will instantly fall back to "disabled".
I've stumbled upon this thread: https://forum.xda-developers.com/mi-a1/how-to/mi-a1-wifi-broken-october-update-t3706504 The diffenence with this guy, is that my "A partition" modem, still works. So I'll stay on it until I get some help here. Thanks
But it's for the october update, and I'm afraid to break things even more if I do that batch commands with an old set of files.
Could someone guide me through or tell me if those files are good to go?
Also, if so, can anyone provide with a smaller download, instead of having to download a full ROM, would be appreciated.
Many thanks.

i am also seeing weak wifi signal strength after march ota update. unable to connect until right next to router.

Oreo firmware issues

Hello respected members, I yesterday flashed that btu oreo rom through odin on my S7 edge G935FD , all went well and phone is working good, but in recovery there are these type of messages, I have seen on forums that many people are experiencing this recovery issue, is there a solution for it? Apparently they don't effect phone in anyway or cause any issues, but still why are these messages showing ? I am just worried about bootloops. Those messages are :
(fail to open recovery_cause(No such file or directory)
Reboot Recovery Cause is [UNKNOWN])(This is still showing in ERG2)
No Support SINGLE-SKU
File Based OTA
Supported API: 3
MANUAL MODE v1.0.0
Sucessfully verified dmverity hash tree
E:Failed to clear BCB message : failed to find /misc partition
Issues updated (OREO ERG2) :
1. First of all those weird "failed to find misc partition" messages in recovery. Don't know if they cause any issues but they are annoying. No bootloops or any other issues though. Happening since first oreo release of 1st May. (Fixed in ERG2 release).
2. Can't go into download mode anymore from recovery by using option " reboot to bootloader ". It just reboots the phone normally. Happening since I flashed the first oreo release using odin. (Still in ERG2)
3. If phone battery gets to 0% and discharges completely, then when plugged in the charger it goes into recovery mode instead of that charging screen. I used power off so that it exits recovery and goes into charging screen, but it again booted in recovery, when I selected " reboot phone " option it turned off and got in charging screen.. strange thing, I never experienced this on nougat, its happening since the first oreo release. (Still in ERG2)
4. Cell standby drain not that high after the 18th may btu update, but still high before it was 33% and screen 20%, now its 2-3% above screen battery usage. Happening since first oreo release. A note here that after flashing 18th may release I think battery life is good and SOT is somewhat same as last nougat release.. (Still in ERG2 release but somewhat more less.. but battery life on ERG2 is a little less than previous builds..)
5. Phone rebooted randomly before 18th may update, now after updating it seems to be fixed. Note that I experienced random reboots but no bootloops or other issues etc. (Already fixed)
6. Fingerprint scanner issues:
Fingerprint scanner becomes unresponsive randomly and I had to unlock using password. This is occuring from approx december or january security patch update and still isn't been fixed in latest oreo. This issue has surely increased in oreo, and now it happens more often and is very annoying to the point I disabled fingerprints.. (still in ERG2, for me, don't know if its hardware related)
Also in oreo, fingerprint requires more time to open the lockscreen, some 1 sec delay approx. Can't say if its requiring more time to match the fingerprints or its taking more time to unlock the lockscreen..
Note : I didn't experienced any connectivity issues in bluetooth, wifi or mobile data..
Some times I had to re-select default network mode for my sim in settings if internet gets hanged and don't works, but it happens very few times and changing network modes in network settings will instantly solve it, and it was also happening on nougat before. And didn't increase in oreo at the moment for me..
Also to tell you all, I flashed back last nougat release for my region successfully, but it looked too much slower and laggy as far as I remember before flashing oreo btu, maybe its because I got accustomed to oreo ( which is faster than nougat ) or maybe downgrading caused some issue maybe. But I don't think downgrading should cause performance issues. Also when I downgraded on nougat I couldn't go into download mode from recovery mode using option " reboot to bootloader " and it reboots to normal mode. I don't remember this, because always this option worked in nougat for me before flashing oreo. Don't know what's the reason but not a big deal. Also I didn't tested after downgrading about fully discharging battery and then putting phone on charger whether it goes in recovery or normal charging screen. Btw those fingerprint issues are a real pain.
Had the same experience, with the phone hanging on bootup and the same message in the recovery screen.
... so I went the factory reset route .... painful, but I could find no option to recover.
I see that there is an entry in the recovery menu for a firmware update from the SD card; can anyone suggest how that can be done? (In case there's a next time).
Did I can to flash without HomeCSC
Because I am in different country????

I flashed via odin, then did factory reset, but the message is still there, but phone works fine and smooth , but with occasional reboots and a strange high cell standby drain. My phone never rebooted even once on marshmallow and nougat.

You have to flash either CSC or home csc, home csc won't wipe your data, but I will recommend flashing normal csc and then factory reset and clear cache too, as to avoid any issues like bootloops etc.

How did you flashed on SM-G935FD? Since so far it's only available for SM-G935F and SM-G930F.

I flashed through odin, the firmware is same for dual sim models , hence G935F firmware works on G935FD too, just be sure that model number is correct, i.e not to flash a G935FD with a G930F firmware or flashing a snapdragon variant with exynos or vice versa.
But now the btu oreo update have been pulled back from the OTA server, due to bootloops / recovery bugs, its better to wait now for your own region oreo update. If you still want that btu oreo, you can download the corresponding rom for your model from sammobile or updato(for faster speeds). But I suspect oreo update is halted and will be resumed again with these bugs fixed along with may update patch near the end of may globally.

I already have installed it on SM-G935F and it works totally fine. The only problem so far I have detected is that when I play a song on Samsung Music with earphones connected, it crashes but it plays normally with phone speaker and secondly this BTU firmware doesn't have Bixby in it.
it seems it was a beta nougat for s7 edge ,because the update is not available anymore only on sammobile.....I received notification last week to update to android 8,but I didn't update and now when I check I don't see the notification anymore ,it says like my current version is the latest...

I downloaded the BTU files straight from Sam Firmwares and only flashed AP, HOME CSC and CP with ODIN 3.13.1 and have no issues at all. So fare everything is stable no reboots lags or freezing. That version of ODIN is updated to handle the compression of OREO.

Yes v 3.13.1 handles the latest firmware, but the update had bugs in recovery and some users faced bootloops, I faced auto reboots whenever I rebooted phone and used fingerprint at a faster rate to lock and unlock phone.

Same here, high cell standby drain. Also battery life is a little less compared to last nougat release.

Can anyone with the oreo update tried using phone in airplane mode? Or without sim card inserted? See if that cell standby drain still occur in airplane mode or without sim? It may only be a bug or android's wrong report of the battery usage ..

Got BTU oreo through ota. No issues whatsoever yet.Phone feels a lot smoother in day to day usage!
I can confirm that there's high cell standby drain.
Battery life is a bit of a letdown as it's a little less compared to last nougat release.
Is it possible to downgrade same way?
Install nougat again and wait for good oreo?

I wouldn't recommend going this route, its better to wait for the next oreo update then downgrading which could brick your device..

Cell standby drain for me.. on light usage without any gaming and with every connectivity disabled such as gps, wifi, bluetooth, nearby and auto sync disabled too. Not such a great battery life, little less as compared to last nougat release as I mentioned few posts earlier.

Stock ROM upgrade needed for G7-L01

Hi
I have a Huawei ascend G7 purchased in the UK from “Carphone warehouse” who seem to have been the only UK supplier of this model
The model is G7-L01
Android 4.4.4
EMUI 3.0
Custom version CUSTC432D001
My problem is a few banking apps I rely on have now stopped working as their updated versions insist on android 5 or higher
There has never been an OTA update for this phone since I purchased It
The only official ROMS listed on their website I can find seem to be for the G7-L11
I contacted Huawei support who confirmed that the particular model and custom version I have has no official updates newer than I am currently running and there no planned updates for it.
What are my options for getting this phone upgraded ? if possible I’d like to go with a stock ROM. could I use one from another region ?
Although I’ve had lots of phones in the past that I’ve put custom ROMS on I’ve always tried to keep this phone as stock because the same banking apps I rely on wouldn’t work properly on my last phone because they detected it had been rooted.
Searching these forums I’ve found a few guides but nothing for the particular custom version I have. I don’t know if this matters ? I don’t want to risk bricking it with an incompatible ROM
Thanks in advance for any advice you can offer
OK this is weird.
3+ years of no OTA updates. I enquire with Huawei and am told there are none and it is out of support.
Less than a week later and I'm being offered an OTA update.
Staggering coincidence ?
Only thing is it is reporting that I should download and do an SD card update instead of an OTA update as it is detecting that my device has been "modified".
I seem to recall I unlocked it a long time ago to try and root it but the root was unsuccessful.
Update is Android 5.1
EMUI 3.1
G7-L01C432B350CUSTC43D002
I just need to find it somewhere :-/

Hi
I have a Huawei ascend G7 purchased in the UK from “Carphone warehouse” who seem to have been the only UK supplier of this model
The model is G7-L01
Android 4.4.4
EMUI 3.0
Custom version CUSTC432D001
My problem is a few banking apps I rely on have now stopped working as their updated versions insist on android 5 or higher
There has never been an OTA update for this phone since I purchased It
The only official ROMS listed on their website I can find seem to be for the G7-L11
I contacted Huawei support who confirmed that the particular model and custom version I have has no official updates newer than I am currently running and there no planned updates for it.
What are my options for getting this phone upgraded ? if possible I’d like to go with a stock ROM. could I use one from another region ?
Although I’ve had lots of phones in the past that I’ve put custom ROMS on I’ve always tried to keep this phone as stock because the same banking apps I rely on wouldn’t work properly on my last phone because they detected it had been rooted.
Searching these forums I’ve found a few guides but nothing for the particular custom version I have. I don’t know if this matters ? I don’t want to risk bricking it with an incompatible ROM
Thanks in advance for any advice you can offer

Hi,
I also got this update notification on Saturday night. I have had this phone for 2 years now and never got a OTA notification until 2 days ago. The phone was working great, good battery life after 2 years and good performance. I use it mainly for youtube, whatsapp, some browsing, music, and calling.
Well, decided that updating to 5.1 would be a good idea but it hasnt. I cannot make any calls (phone disconnects and connects constantly to the mobile network, so every 2 seconds the "only emergency calls" message pops up and doesnt let me make calls). Same for receiving calls, when someone calls me it rings for 2 seconds and then it appears that call has been hung up, then it rings again, 2 seconds and hang up again... the constants connections and disconnections are drainning my battery (from 100% to 7% in 1.5 hours). Contacts didnt work and also messages either. As you go into one of them, it kicks you out of the list to the main screen. Of course this issue affects Data Mobile; I cannot use my phone internet unless its by Wifi.
Going into airplane mode stopped drainning problem plus contacts and messages are working now, but as soon as you turn airplane mode off you wont be able to go into contacts or messages/signal problems back.
Nothing of this happened when I had 4.4.4 version, so its clearly a software issue. Im gonna try doing a hard reset/factory defaults, since I could backup my contacts. And if this doesnt solve the problem, I think the best idea would be custom ROM/go back to 4.4.4.
This is a good phone, if good software is installed on it. It can last some more years.

Hi. I had exactly the same problems on my moms Ascend G7. She updated that OTA and mobile network got constantly shut off and on again. I solved it by doing a backup by Huawei HiSuite over PC. And then reflashed version 340 again manually (instructions at Huawei-Blog). Mobile networks are working again after flash but phone is still not working 100% correct. She gets randomly her mic muted in most calls, or recently her "back" button in navbar disappeared today...?
I'll either downgrade to 4.4.4 version or try lineage os soon.

I solved it too! In my case I backed up my contacts to the micro SD card and did factory wipe/reset from the recovery menu (by restarting and pressing vol+ + power). I had all my data in my micro SD card so there wasnt any need to backup or anything. After doing this factory reset everything is working fine: phone signal, calls, contacts, messages, battery life, etc. I installed back the few apps I had and now everything fine, even performance is good! same as in 4.4.4. Im gonna stick with lollipop for a while, If I find any issue itll be time for a custom ROM or downgrade to 4.4.4
Cheers:good:
