[Q] Nubia Z5s, WiFi Issue, Hardware or SoftWare?

Hi!
I have posted this message on another thread, but it's important so I create a special thread for it.
Indeed I received my Z5s yesterday and I have 1 week to find out if my WIFI issue is hardware or software. In the case of hardware, I need to send back my phone to china .
I received the phone rooted, so if I want to install the last update from nubia (1.30) I have different manipulation to do. Howevver, I am afraid that if I touch the rom, the seller can tell me "you changed the rom, before it was working so it's your fault. we don't give you back the money!".
So I am waiting he allows me to put back the official rom 1.30. By the way if anybody has a good tutorial (in english) about unroot and changing ROM, I would be very grateful
There is the description of my WIFI issue:
First (yesterday) I couldn't find any WIFI and then after a factory reset, I could find some wifi but not everything. By example in my laboratory, the general WIFI of the school appears (and is working) but not the wifi of my lab... Anyway I found out than others WIFI were missing too. (Maybe 15 were alright on 20).
Now (today), in my lab, I can't even find 1 WiFi! I have tried the factory reset and it still doesn't work. In the description of the last update (1.30), I found "6. 修复wifi小概率无法打开的问题 = Small probability can not open wifi fix problems".
It looks like my problem fix except that in my case it is not a small probability but it (almost) always happen...
So I need your expert opinion, do you think it is more probably hardware issue or software issue? Does any Z5s owner have this problem (sometimes or alway)? I've bought the phone in Eternal Team on Aliexpress, I don't know what is their custom ROM, did anyone buy the phone there and know what is the ROM ?
Thanks in advance for your help!!

Wifi issue
Nobody can help me ?

No Wi-Fi on Nexus 5 - on any version of Android

The Wi-Fi on my wife's unrooted Nexus 5 (Sprint version) which was upgraded (via OTA) to Marshmallow last month suddenly stopped working last week. The slider would get hung while moving from Off to On (like it was trying to turn on) and therefore was not detecting any available Wi-Fi signals.
After trying many things, I eventually did the extreme and did a full factory data reset. No dice. Still not detecting anything.
Figuring it might be an OS issue with Marshmallow (given we're seeing a lot of forums indicating Nexus 5 issues based on Wi-Fi with both Marshmallow and Lollipop), we downgraded the OS first to Lollipop and then all the way back to KitKat (4.4). Still not working. At initial phone setup, the phone is not detecting any available WiFi signals and gets hungup trying to find networks for me to choose from - so I end up having to skip this step.
Any other tips out there on what I can try? Is this a sure sign of hardware problems? Don't think my wife's phone is under warranty any longer (have had it slightly over a year, I think).
PS - Now I can no longer even upgrade the phone (OTA, at least) from 4.4.4 because my phone is saying it needs Wi-Fi to download the update - with no option to do it over my data plan.

I'm in the same situation and it appears to be a hardware failure. The wifi chip can't be replaced so a motherboard swap is required.
You can upgrade to the latest stock ROM by flashing the entire ROM from a command prompt in Win7.

Plot thickens
So, I figured out a way to get the OTA's over LTE (by manually changing my phone's date up a week). While going through each OS update from 4.4 KitKat to 6.0 Marshmallow (about 5 or 6 rounds of them) my phone briefly was able to detect WI-FI, I believe during set up at 5.1.1 Lollipop - and I was able to get on my home network.
Probably should have just stopped updating after that, but definitely was not detecting anything after that. I lost it during one of the Lollipop updates - well before getting to 6.0. Not sure if WiFi was actually working well or not.

Maybe the chip is in the process of failing? Not sure but it seems like you are having better luck than me.

I wish. Don't want to go through all those steps again after doing a clean wipe to have a fleeting glimpse of Wi-Fi.

Hi, pagalbengal. I'm having the same problems right now, and I wanted to check with you to see if there have been any developments with your situation over the past month. Still hopeless? Have you contacted Google tech support? Do they still even support this phone? Thanks for any info.

You guys might want to try reflash the modem firmware.

Couldn't get my wi-fi to work so I replaced the motherboard. Every stock and custom ROM I tried could not enable wi-fi.

[Bug] Blank Toast above home button (Solved : I think VoLTE sim related)

(Solution)Update : I did little bit more (well, honestly a lot more digging ) It turns out this wasn't Xposed or Rom or anything related to specific setup related after all !
Many users had same problem ( Random Grey bubble above home button / Black Toast) in past in 5.1 & 6.0 as well & even on Nexus 6
I THINK as described by user on Androidcentral it's related to specific SimCard & my guess is, it happens on VoLTE simcards (Specific Reliance Jio in my case ) because i have other 4G sim (Vodafone) without VoLTE and i'm not getting any "Blank Toast" after inserting it
here are some of links i found while digging and IMO 1st one is somewhat correct about occurrence of issue. ( i'm with him bcz i having same experience till now)

https://www.reddit.com/r/nexus6/comments/3neppi/i_have_constant_toast_notifications_on_my_screen/
https://code.google.com/p/android/issues/detail?id=196384
as you see in last link someone reported it to google but they didn't take it seriously with not much data.
even though i believe i have enough data, i'm not gonna report it again because i don't have patience to deal with official channel :silly:, that's why i'm writing this long post with almost everything i got, to help someone looking answer related this in future & for any philanthropic who wants to report & deal with it
may be it's due to lack of VoLTE related hardware in N5.
(all above points are just my speculation through data i got, i'm not certain about root cause, but i hope to never see that bug on other Sim Cards :fingers-crossed: )
Problem
As you can see from attached SS , i'm getting this annoying grey bubble randomly (any app/game , any time ! nothing is specific about it's occurrence that i can find ) i got that bubble at-least 5 times while writing this post as well !!
So is it just me or someone other also have same problem ? If someone had similar problem in past and have any solution plz tell )
My setup :
M4B30X Stock (dirty flash over September) + Systemless SuperSu 2.78 + Xposed v86 (official) + gravity Box
(If i'm the only one having this problem, then i'll Clean flash system but if someone ever had similar problem kindly share solution bcz if possible i want to avoid the clean flash )

Seems like an empty toast message.

Running M4B30X since yesterday, and there's no grey bubble on my end.

Sideload OTA now. No issues

yah i re-flashed it without Xposed and it's working fine now so i guess it was the issue. anyway thanks for confirming
btw today i'm going to flash Pure Nexus bcz i can't live with this un-customizable stock for long and xposed & cataclasm mod giving new & new errors so that's it for me with security updates i'll live happily with older august Pure Nexus as long as i can resist update LOL

download from PC. it'll most likely complete.

OP updated with possible solution

Based on your findings, could you try Deleting sim toolkit APK to test if it goes away?, im assuming its interpreting some kind of mesage as ADs from your carrier, however it fails and throws an empty toast

thanks for suggestion but it was debloated before i clean flashed factory image, so i guess it's happening regard-less of STK's presence or not

Cyrus CS28 alternative rom ? outdoor phone

Hi together, I bought a cyrus CS28, because my phones broken in the past very often It is not easy to find a rough tough phone which is looks good. (more or less). But I have a lot of trouble with the phone: Android 6.0 (no newer android versions are annnounced) is onthis phone a little bit buggy....
a) sometimes the connection is not stable to known wlan networks and the connection is on off without any reason. Only a restart of the phone helps and / or the reset of the network settings helped. I tried to ask the support, but they asked me only - lease reset the phone and / or sen us the phone. But: I ordered a new one and there occures the same troubles during the first 2 days.
so my idea is to root the phone and install an alternative Rom. Is anybody familiar with this phone and suiteable Roms?
b) sometimes the microphone is not working and only the toggle between headset , hands free set(bluetooth) is helping.
so - my question is: could anybody help me to root the phone and install an alternative Rom?
Thanks a lot.

Hello, unfortunately there was no answer to this question! Now I have the same phone and the same question. May be there is an answer now?

Xz3 - 52.1.A.0.672 RU version

Xperia XZ3 (H9493) - 52.1.A.0.672 - RU version
Notification seek bar bug - STILL!!! – If I’m playing media through chrome, soundcloud or another app, the notification seek bar does not work in most situations. This has been a bug since the initial Android 10 roll out and I’m still shocked that we’re still going through this.
Swipe up from the lock screen – I’ve noticed this since the update from Android 9 to 10. It used to be a quick flick of the thumb where I could go from the notifications on the lock screen to the security pattern. Now since the A10 update, I can’t do that anymore. It is a longer swipe, more exaggerated swipe to get to the security options. It was easier with 1 hand before and it needs to go back to whatever it was in Android 9
Camera – Still gives error unknown error. It’s MUCH EASIER to fix than the first and second android 10 releases but it still shouldn’t be like this. It’s at the point where I don’t know if it’s an actual software or hardware problem. And with everything that’s going on, I probably won’t be able to confirm for the next 6 months. I'll probably end up wasting$200 fixing the hardware, that was really a software issue all along.
Fingerprint – Good, I believe either at or close to Android 9 speed
Battery – Good
Networking issues – I believe better than the last update. It seems good so far so
No idea why the software version has to be in the notification quick settings. That doesn’t need to be there. It’s out of place/doesn't add value by being there
I am so frustrated by Sony. They’re taking steps to fix this but damn you should have been on the ball. I do a clean install each update because I don't trust Sony to do this correctly.
This phone is like the Renault Formula 1 team. It's a great product and each update is a step further but holy **** you all should have been a lot farther along by now. Now Mclaren (One Plus) is starting to pass you.
Edit: I forgot to add this earlier. I found a bug by random. In dark mode, About phone -> Emergency Information, the notification bar text is black. So you've got a dark screen with black text.

I still have not received an air update on my H9493. my software version is still 532.

It's possible it's a hardware problem. It happens to me too but it was worse with the initial A10 update. My understanding is if you squeeze beside the camera when turning the phone, it can solve the issue. This is because it's a possible loose ribbon.
The initial A10 release was terrible so flash up to .672 and it may fix the problem (if it's a software issue)

Hey I am also facing this problem on my xz3 dual. Failed to restart the camera is consistently occuring in the past few weeks but restarting the phone worked then. But now its been almost 2 days, camera app says unknown error, I tried everything mentioned above but still unable to resolve the issue. Kindly let me know if downgrading the firmware resolves the issue.
Thank you

Today I downgrade my Xz3 H9493 to android
9 but my camera didn't get back.So I decided
to check hardware.that is really sad.
Coz I have to take out all water proof
Seal from my back cover .After that I found
my Camera connector is loose.That's why
occurring unknowm error and after
2 or 3 days is good again.At last that is
not a software error at all.

I got error while enabling tethering
Anyone else?

I'm having signal issues. Dropping connection all the time. Latest firmware hurt this badly.
Same SIM on a Samsung A30S on android 9 works fine.

Hello guys. I need your help finding 52.1.A.0.618 for H9436
