Wifi unable to reconnect when coming back in range

I have this rather annoying problem with my OPO: When I'm on WiFi and go out of range and get within range of another WiFi (eg leaving from home in the morning and getting on the train where there's also WiFi) my OPO will not connect.
I've tried switching WiFi off and back on, tried forgetting network and connecting again but the network just displays as "Saved". Only thing that works is a reboot. Funny thing is that it actually detects open WiFi's and displays the question mark in the notification bar.
I've read that themes can cause WiFi problems so I haven't changed that. I'm using the Apex launcher with no visual changes.
I've rooted my phone but left the bootloader locked.
Any advice?

I'm rooted with the TWRP custom recovery installed. I had the same thing happen to me. If you toggle airplane mode on/off, it will reconnect. But, as for a solution, my fix was to restore a previous TWRP backup of my phone. I also had heard that the problem could be coming from a theme. What themes have you used? I bought the Flux theme and have been using its style and fonts. I was running the stock CM11s when this happend just a few days after getting my OPO. I would try a factory reset first. If that does not work, there is a thread in the OPO forums about flashing a factory image and getting back to 100% stock.
I have switched to the CM11 nightlies as of a couple of days ago. I will probably refrain from messing around with the theme packs for now.

Will probably unlock the bootloader. Then a factory reset should be taken care of I guess...

Anyone have a solution to this? My OPO is having this problem too and it is rather annoying...

I'm now on KTU84P and the problem is still there
Yesterday I failed to flash MAHDI and ended up clearing everything from my phone. I had to follow this guide:
http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541
to get back to pre-KTU84P (can't remember the build number).
So I guess it's safe to say that my phone has had all sorts of memory cleared. And the problem is still there...

I really hate to hear that you are still having the wifi issue. One would think that if you flashed all partitions with a factory image that it would solve the problem. You might want to have a look at this thread. This guy was unsuccessful in fixing his efs and bluetooth problems until he flashed Color OS and then went back to CM. Have a read: http://forum.xda-developers.com/oneplus-one/general/fix-people-corrupt-efs-mobile-data-t2836389

Thanks for the link.

Flashed Mahdir ROM yesterday and though the rom works just fine my WiFi reconnect issue has not been resolved
I find flashing yet another rom (ColorOS) sounds a bit drastic. Really no way of debugging what's wrong?

No. I'm waiting for the update to hit my phone and install it to see if that solves it. In the meantime though, I installed an app called Smart WiFi Locker that seems to keep the issue solved (for now)

Thanks for sharing. I think there are two things that can produce a major restore/fix to a phone - a nandroid restore and a major rom update. I hope it fixes yours. The nandroid restore is what saved mine.

Been there. Done that. Read the book. Got the t-shirt.
Flashed ColorOS.
Factory reset.
Booted and got through into ColorOS (skipped account setup).
Booted into recovery.
Factory reset.
Restore backup of CM11S.
No dice :'-(
What are my options now?
A couple of days ago I completely wiped my OPO - radio, modem, everything and flashed a new stock image. Nothing has helped.
I really find it hard to believe this to be a hardware issue.

Just for clarification - after flashing Color OS, did you turn on wifi and use it to see if the problem was still there while in Color OS?

If your WiFi 2.4 or 5GHZ?

Yes. I would recommend you consider doing that. If it works then I would flash a fresh Cm11s rom, not a nandroid backup. Flash the Color OS and do a full check of the Wifi.

I was having the same issue, but here's what I did and it seems to have resolved my issue.
1) Updated firmware on my ASUS AC68 router
2) Boot into recovery mode (volume down+power), wipe cache and media, then factory wipe
3) When setting up phone, did not apply CM theme on the options after logging into CM account.
It seems like WiFi might drop when you get to homescreen, just reboot phone and Wifi should reconnect. Make sure to go into your WiFi settings and remove any networks that was saved, and re-add.
Still not ideal (since it seems like themes might be killing WiFi for some users), so hopefully a new OTA update will solve this problem.

Reboots all the time since the latest OTA update

I've just received an OTA for my P900 (bought in UK, completely stock, not rooted, P900.XXUANI1). Since then the tablet has been rebooting randomly several times a day. It's a funny sort of reboot where the tablet is back up and running almost instantly, not like on a usual startup. The screen goest black, the "Samsung" logo flashes for a half a second and it's back at the lockscreen. No blue-lines-logo animation that goes with a usual startup, but all the apps I was using are closed and the recent apps list is empty.
Is anyone having the same problems? Any ideas on how to fix this?

You can try a factory reset.

I know I probably should after an update anyway, but I'd hate to have to set up the tablet all over again, so I'll give it a few more days. I was wondering if anyone came accross this problem and found a different solution. Some people mentioned their ATT version crashing and how un-disabling an app has fixed it. I don't have an app called My Magazines though, so that's no good. I have a bunch of apps disabled though. Could any of them cause such funny behaviour?

I think it is a problem on several firmwares, and the devices are rooted.
I fixed it using the Xposed Framework and the Wanam addon.
Or you can try the http://forum.xda-developers.com/xposed/modules/samsung-kitkat-systemserver-crash-fix-t2806046 add-on.

Thanks, this seems to be it. It looks like I'll be rooting my tablet when I get home today I should have done it ages ago anyway, if only to set the desktop user agent in the browser and get rid of adds.

Well, CF Autoroot didn't work for some reason. Now the system won't load at all (I can still get into download mode). Anyway, I described the problem here, if you can help, please let me know!

Then install SuperSU from the app store. Then try to flash CF Autoroot again. Good luck. And let me know if the file CyberDie1 referred to us worked for you.

Thank you so much, you just saved me a trip to the service centre. I've followed through with the first three steps and it booted back into the system I wish I could give you more than one "Thanks".
I don't have time to go through the rest of the steps today since I still have some stuff to do for work, but if the tablet keeps "rebooting" I'll be back in a few days to root and report how it went with the Xposed module.
BTW, I haven't been able to find the file "openrecovery-twrp-2.7.1.0-v1awifi.img.tar" the guide mentions as no. 4, and no other twrp version for P900 (only P905) on their site. Do you maybe have a link for that?
And big thanks again!

I'm also at work so I'm not at my computer. I think I found that file by doing a Google search for it. Yes, let me know if it keeps rebooting. I have my own tablet rebooting issues (as you can see in one of the other threads, heh). I lost my root by reinstalling SuperSU one too many times... I blame it on trying to change settings before reinstalling because I was trying to achieve something.

I tried googling, but like I said, the official TWRP site did not have a file for p900, only p905. Here's the list of all the supported devices on their site, I only see p905 and 3g variants.
Then there's this site. I didn't realize that "v1awifi" is the part that refers to p900. I'm going to use the latest version from here today and try to get root again. If I succeed, I'll then try the Xposed package. I only had three reboots in the last 24 hours though (which is much less than before my first root attempt), so it might be a while before I can be certain the reboots are gone.
EDIT: I rooted in a few minutes without a single problem. Xposed and module installed, starting the clock for reboot-watch now I'll report back immediately if I get a reboot, or in 24h if I don't.
EDIT2: It looks like Xposed with the Samsung SystemServer Crash Fix works. The app posts notifications when a crash is prevented, and I've just had three in the last hour, with no crashes.

Best of luck. I tried that Xposed and Wanam module combo and it seemed to work for most crashes. However, I still get reboots when I wake it up from sleep after a full charge (from my experience).

Try the other app, the SystemServer Crash Fix. I've just charged up my tablet for the day, and when I woke it up while still plugged in, I got a crash notification. I've also had a few more yesterday. So far, not a single crash, it worked every time.

I also installed the System Server Crash Fix, but it didn't prevent the reboot. Hopefully it works for you!
I purchased Titanium Backup and froze all the Knox related processes and apps, but I still got a reboot. So, I just did a factory wipe on the tablet and rerooted. This time it prompted me and asked about disabling Knox. This time I chose cancel instead of disable. Crossing my fingers now. If I still see a reboot tomorrow morning I will probably forget about rooting my tablet.

Just adding in. The SystemServer Crash Fix is an Xposed module why you also need to install the Xposed Installer. First validate Xposed, then the crash fix app, finally reboot and you're done. Finally, just pray that your issues are gone...

I went halfway between your approaches. I chose to disable Knox when asked, but I did not freeze any of the apps with Knox in the name in TB. First, I reset the default apps settings and then used TB to freeze a bunch of bloatware, but nothing with Knox in the name. The only such app currently frozen is Knox Notification Manager 1.0. Also, I never installed Wanam module, just SSCF.

I have the same problem, since I upgrade my T900, I have the same behavior you described.
Read a lot and tried everything, even Xposed Installer. Nothing corrected it.
I didn't test this firmware version it without root (can't live without it!).
If what you said that you have the random reboot without root, I really think that this firmware release is buggy.
I will now return to the previous firmware.

There's no doubt that Samsung is at fault. My tablet was stock, unrooted, in no way modified, and it still crashed several times every hour, usually when screen timed off and was turned on again, but also on other occasions. I would flash an older version too, but then I might have to do a clean install and set it up again, so I tried root + Xposed + SSCF first, and fortunately it worked. With the added benefit of Desktop User Agent in Chrome, no ads and a much snappier tablet. I should have rooted months ago

Adblock Plus version 1.2.1.325 works fine for me. It allows some unobtrusive ads through by default. If you want to block all you can, but you have to manually enable it in app settings.
If a particular app is still showing ads it sometimes helps to clear the cache.

You could always try installing them the right way round to see if it will make a difference. I think I installed both apps at the same time, but then I opened Xposed, activated it, rebooted the tablet, then activated the module (which showed up in Xposed automatically, IIRC).
First, you should double-check that the SSCF is activated in Xposed, if it is not, it won't stop the crashes.

Lineage OS - problem with wifi and HDR.

Hello everyone.
I have 2 problems with LineageOS on Oneplus One.
First HDR does not work properly. I can not do a photo with HDR enabled.
My another problem is with WIFI. Many times I have lost connection to internet without report, and I must reconnect manually. My phone is connected to router but without internet. It is very annoying problem for me.
I fashed:
lineage-14.1-20170206-nightly-bullhead-signed.zip,
Gapps Android 7.1/Lineage os ARM Pico ( other did not work because of low free space of disk. I have 50 gb free. Weird )
Latest Super Su.zip
I flashed them all at once. Was it good idea? Or I should flash them separately ?
Of course I did clean wipe before installation and Wipe Dalvik,cache after installation.
Thanks for replies

Same issue with the Wifi here

Well, I flashed again system, gapps (pico) and root but now in sequences.
- flashed room (after wiped dalvik/cache)
- reboot to recovery
- flashed Gapps ( after wiped dalvik/cache)
- reboot to recovery
- start phone
- reboot to recovery
- install root
Now everything works fine Even wifi so problem is solved.
Maybe someone will solve his problem by my guide.

That didn't work for me.
Anyone with another idea?

The "heartbeat fixer for gcm" app seems to be doing the trick for me.

For hdr; go to play store and download cyan apps app and go inside, download camera(basicly it updates the camera app to the latest version and hdr will be fine)
For wifi; i have whole topic about it. This problem happens rr remix tugapower and lineage(those 3 are the only ones i tried so i dont know if it happens on different roms) and i kinda fix this by installing c7 modem(it only happens like twice in a week or not at all) so maybe you guys want to check it out. @mad.maximo

Thanks! Flashing the radio firmware seems to have solved it.
Great!

flashing the c7 worked!!! at last!!!! tks for the tip zaoms

I'm on TugaPowerROM N21, and I solved the HDR problem with Bacon Camera app (available on Google Play Store). IMHO the best camera for our One.

The low free space warning message is related to the filesystem (/system) where GApps had to be installed. /system size is fixed (about 1.3 GB) and it cannot be easily resized. Even more, a full block-based OTA ROM update will potentially restore default /system size. So I will stay with Pico GApps, IMHO the best choice.

Thank you alot
I solved issue with wifi. I do not use HDR so rom is stable for me

Hello @zaoms please help me with this. I was on CM 13 and my oneplus one started hanging so I decided to do a factory reset. I did that. After the reset I had a new problem, the WiFi dropping one. I was very frustrated as it would drop every 8-10 mins. And then reconnect. I googled but no solution provided worked. So I decided to change the ROM since CM was down and I wasn't going to receive any updates.
A couple of days ago, I shifted to lineage os 14.1. But now I have a new problem, the WiFi doesn't drop now. It stays connected but every once in a while, it'll not share any data. It stays connected but the internet service won't work. I saw your solution and I flashed the c7 modem as you said yesterday, but I'm still having the problem.
Please help me, I'm very frustrated because I lose connectivity during games or while chatting or even downloading.
Thanks in advance.

Well the only thing about this problem is flashing c7 modem. But there is 2 types of c7 modem one is 00013 which is my recomend and the other one is 00011. Make sure that you flashed 00013 one and if it still exist you can try different modems from the modem topic. Let me know the results.

im on rr 5.8.1 , can i just flash the modem or what ? thx

aksksky said:
Hello @zaoms please help me with this. I was on CM 13 and my oneplus one started hanging so I decided to do a factory reset. I did that. After the reset I had a new problem, the WiFi dropping one. I was very frustrated as it would drop every 8-10 mins. And then reconnect. I googled but no solution provided worked. So I decided to change the ROM since CM was down and I wasn't going to receive any updates.
A couple of days ago, I shifted to lineage os 14.1. But now I have a new problem, the WiFi doesn't drop now. It stays connected but every once in a while, it'll not share any data. It stays connected but the internet service won't work. I saw your solution and I flashed the c7 modem as you said yesterday, but I'm still having the problem.
Please help me, I'm very frustrated because I lose connectivity during games or while chatting or even downloading.
Thanks in advance.

Hey Buddy! I've observed it for 4 days now. Wifi stopped twice till now. That's better than before. Let me know if there's a permanent fix though.
There's another problem, my Oneplus One gestures aren't working.

Cool! I am using c7 and thats is the most you get. At least i cant find any better. But in time you will see it will happen even rare. I dont had not even single in a 2 weeks from now i guess. About the gestures, i am using the 2102 lineage os build(which is deleted for some reason) and it is working flawlessly. Which means it will be okay with next update so just wait until the new build arrives(about in 2-3 days) and i guess you should be fine.

Yeah I could do that, but I would like to understand whats going wrong in present case, I have had flashed CM11 many times since past 4 yrs but never faced such an issue.
I even installed TWRP and SuperSU latest version and also Old versions, I tried installing old versions of apps, but phone keeps crashing! Wonder whats wrong?!
Is this a firmware issue?(Tried flashing firmwares too)
or Partitions gone bad?
I tried searching but couldnt find any resource on how to recreate partitions.
Can anyone help please?

Wait,what if you flash cm11? I mean you just wanna stay on KitKat,so why don't cm11?
https://www.androidfilehost.com/?fid=24052804347767866
Clean flash this cm11 nightly+gapps you like.
Make sure you use latest twrp.

Same issue here. Happens not to all apps though. Just particular ones after updating certain apps. Not sure what happened. Only solution is to avoid installing those kind of apps.

Lost SIM signal again! Please help!

yesterday I got it happened again: one of my sim cards suddenly lost signal. completely. and since then it keeps happening so randomly. please help!
im currently on oreo 41.3.A.2.75, BL unlocked, kernel packed by serajr's tool using ta_poc method with my own original TA, magisk installed, systemlessly xposed. i got it all working fine. until this issue happened.
i've also tried different ways: reflash, wipe data completely including sdcard, switch to DRMfix method, remove app by app, remove xposed... even switching SIM slots.... no luck so far.
about the issue, it just happens randomly without any clue. one of my SIM card just disappears. sometimes this one, sometimes the other. until now the only way is restart and pray it won't happen again.
please help! please!

Bro I'm having the same, loosing randomly my second sim card... Thought it was caused by some apps abusing of phone permission, but no luck it's not that. I cleared cache and art yesterday, now it's has not happened, but I guess it will happen again soon

it will, unfortunately. i tried almost everything except uninstall magisk, lose root and restore TA & stock image. maybe it will fix the problem but whats the point if we no longer have root right?
back to nougat it was running flawlessly so i have a doubt that it has something to do with the combination of oreo + magisk + ta_poc method but i have no idea.
in ta_poc method i see it executes something like ua_modem_switcher. does it has something to do with modem?
@serajr you mind having a look pls. sorry to bother you the master but im running out of hope...

Yes, removing magisk will lead to loose root access. But we can keep SONY features with kernel and TA.
The idea is :
-trying running stock OREO without root
-then adding custorm kernel with or without TA (original or drm_fix)
-at least adding magisk
I guess we need to try each step for a while
Maybe Serajr will have an idea, on my side i will try these steps and report...

highly appreciate that. i will do some more testings on my side too. the point is, although i know it will happen eventually but it happens so unpredictably its not easy to reproduce.
it may sound odd but you're here so i can at least hope it is just a software problem not hardware.

I was never be able to get my xz working with magisk 15 or 16. Always get the sim not recognized problem, maybe yours is magisk related.

My phone is working fine for some days so far. Just cleared cache and dalvik as I mentionned earlier. BTW before doing this I've updated my Magisk from 15.3 to 16 without clearing anything (maybe the problem is related). Will report soon if it's still working or not...

I did that, many times. clearing cache and dalvik seems do the trick. but it actually doesn't. it will work for a few days and the issue will happen again. unfortunately.
by the way I spent some times paying high attention to the screen just to wait for it to happen. It looks like the moment when it happens, SystemUI (or Home Launcher I dont know) is terminated (stopped) then I am brought back to lock screen and at that moment, one of my SIM gone. So to me it looks like a service (or an app) is terminated and isn't restarted properly?

have you tried using stock rom and see if the problem persists?

@Pandemic hmmm im not saying i dont believe but how do you explain it runs just fine for days after restart? usually 2 3 days then it happens.
and like i said the moment when it happens it looks like the whole systemui and running apps get force stopped.
lets say im playing a game then it becomes a bit laggy like its running out of memory then everything just closed then im brought back to lock screen and one of the signal indicator on status bar disappears.
do you happen to know any command that can restart the modem / cell / signal service? or any services related? just wanna try to manually execute it see if it fixes it.
also wanna mention again that im using ta_poc method for the drm sh!ts and it does have something like ua_modem_switcher executed. no idea whether it could be related

Hy guys, juste a quick update, my phone was working fine until 2/3 days. I've removed magisk but problem still happening, even clearing cache and dalvik didn't fixed it. My guess is, it could it be app related or crash due to RAM to high (my ram usage average is about 2.5 Go/day)...

Hi guys,
I have the same issue on a Note 4 (sm-n910f)....
I have been flashing roms in a long time and this is the first time it happens to me.
For me, the phone shows some lag, it auto restarts and the signal is lost. I can get it back by clearing delvik and cache, but this will happen at least twice a day.
I flashed stock and the problem goes away, does not happen even once on stock. So this tells me its not a hardware issue (i was so close in thinking its a motherboard issue)...
From reading various threads on this, i get to the conclusion that it is not device specific.
I have flashed half a dozen roms and only stock eliminates the issue. I stayed on stock for 3 days no issue, then reflashed lineage 15.1 and the problem is back. The really weird part is that this happened suddenly, not after a new flash or any operation on the phone.
Anyone figured this out?

Adding some additional info from my experience:
- Tried flashing latest BL and CP files (using odin) without any luck
- Tried various 15.1 roms as my device is not officially supported by lineage, again no luck
