Question Network unstable - Xiaomi 12T Pro / Redmi K50 Ultra

Edit: I fixed it, apparently there was an issue with the sim card and they changed it for me. Even wifi was unstable imagine that!
My 12T Pro has an unstable network whether it is through wifi or through cellular network. Whenever I test it through the mobile network diagnostics it shows normal results. But.. and sorry to say this, whenever I am on TikTok it says unstable network sometimes.
And when playing a game called Rush Royale it disconnects me very often..
I bought this phone a few months ago so it is very frustrating for me..
I searched Google for answers I could not find any that solved my issue.
I updated my device to the latest version.
I live in The Netherlands.
Kind Regards!

S3 wireless signal problems

Hello. I bought a S3 Pebble Blue 16gb about 6 months ago. The prone its not locked and camed from Free Mobile network in France. Since then I had wifi problems ... signal dropping, constant speed 5Mb, no wifi N. I waited for new firmwares ... tried modified ROM's like Omega but still no luck. With the new ROM for France JZO54K I can see some small improvements (the wifi connects a little faster and there is a small increase in speed) but the wifi is still pretty unusable. I have 3 different Wifi N Routers at Home and all connect for a brief time at 65MB or &@ in wifi N and then drops to wifi B or G down to 5MB or 1 MB. When I connect for 30 seconds the internet works well but after that u cannot use it anymore ... the speed is very very low. The 3G network works a lot faster than my wifi. I have tried different routers and the same results. I invited 2 of my friend with Galaxy s3 and their phones connect ok in wifi N 72MB to my router. I have a Iphone and Ipad that both work well on my network so the routers are out of the question. I have tried all the "fixes" i could find on the internet with no luck. Do you think this could be a problem that the guarantee could fix it? I dont want to send the phone and to get it back the same when they see that the wifi works ... but with 5mb ....
I made a small movie to explain the "things" better.

I have the same problem, although my phone worked perfectly for about 6 months. I thought in the beginning that my WiFi chip was broken. through multiple drops from small distances. But I can't help you more then just saying that I have EXACTLY the same problem. The WiFi at home works for my PC, MAC, Ipad, Iphone(s), and all my other media, flawlessly. So the only thing I can think of is that we join forces and search the forums and keep track of new ways to fix the issue. Good luck and please post back if You find the solution.
Thanks for the reply. I'm considering calling Samsung for the waranty but I allready know their answer ... "does the wifi works ? ... yes ... Well there is no problem" and the waiting time in France I heard its from 2 to 6 weeks ...
There are some smart solutions one can try but they require some software on Pc and so forth. Look at the post named (my galaxy s3 won't connect to wifi), on the Q&A section for sgs3 here. They give some tips

Hi dude.
Now after some time I have a working phone. This phone has given me more then one headache. The wifi problem I had seemed to be kernel specific. When I started with faryaabs supernexus rom M1 (latest) the phone seemed to work. Instead the phone startes freezing. I solved this to through the DFG method in the ulultimate freezing thread here on xda. So my recommendation is to root install cmw recovery and try faryaabs latlatest rom. Heck you might like it.
Im currently on the leaked 4.2.2 touchwiz. Works ok!!
Cheers

Depressing problem i cannot solve! wifi issue

So heres a real annoying problem, so much to the point im starting to become depressed :/
Nothing major change that i know of, my phone worked great until like a week ago. The problem is with the wifi.
It connects and all, bit it acts as if its just slow connection, but its not because on my computer / laptop its fine. for example, youtube wont load a video, i cant download a single thing from the play store, even facebook is acting wierd. But as i said its connected to the wifi.
Now for the last weekend i went up to my brothers, and the wifi on my phone worked flawless. This is what confuses me. :/
Original s3, no root or nothing, jellybean ofc.
Any ideas anyone? :/

I got a router, and all devices connect to that, what i mean was the problem i dont think it can be with the internet itself because this issue dont occur on any other devices. if that makes sense.. :S
Your S3 has definitely got a unique IP address? You haven't set it static have you?

Yep, Its set to DHCP. So i guess, because the other option is static.

Not detecting SIM card, WiFi not working

Hello everybody,
I made this account specifically for this one problem, and i don't belive i've seen it before on this site. Alright, let me cut to the chase:I've had a Galaxy Trend plus for about a year and a half now (an oldie but a goodie) and i use it as my daily driver, mostly for emulators and WiFi. With one of those two knocked out, i'm desperate for help.
Okay, so all of a sudden it displays the no connection icon like a crossed circle thingy, and whenever i turn on WiFi, it won't detect it even 10 inches from the router. I've never had this error and i'm pretty concerned. My SIM card works on my friends phone, however. I've looked everything there is to look up, and i've done everything software-wise , which makes me think it's a hardware problem. If it is, is it under the warranty or not?If I can't make phone calls or browse the Interwebs, the phone is pretty much useless. If you guys have any suggestions or ideas, please help out an old Android fanboy

Redmi Note 3 Pro call quality issues with one mobile network operator. Wierd signs...

Hello everyone,
Let me begin with saying that i've already contacted MIUI support as well as i've searched other MIUI forums for the solution of my problem, wich is really strange to be honest.
I own an original Redmi Note 3 Pro (previously i owned a Redmi Note 3G). I use the largest mobile network operator in my country and he gives all his customers the ability to use other mobile network operators range/connection in roaming for free whenever we like. It doesn't support 4G from different vendors, so it's 3G max. This is important factor later in the story.
__________________________________________________________________________________________________________________________________________________
The phone was originally shipped with MIUI China Stable ROM wich run fine but as you know it had a lot of crap in it including adds and a lot of wierd chinese apps. But it DIDNT'T cause my any trouble with phonecalls quality.
I used MIflash & download mode to flash the latest MIUI Global Stable ROM, wich in the beginning didnt cause me any problems with phonecall quality.
HOWEVER. After 1 week of using the phone, one of the updates for Global Stable came out. Phone was updated without any problems and it run fine, but i noticed that whenever im talking with someone the quality of the phonecall was lower then ussually.
Then another update came out and it was EVEN WORSE. I thought it's the issue with the ROM itself so i patiently waited to get my permissions for unlocking the device.
I finally got it so i flashed my phone with MIUI China DEV ROM, installed TWRP and installed the latest MIUI available for my country (wich i previously used for over 2 years or RN 3G) wich also includes fixes and optimizations. HOWEVER the problem still occured.
I then started to blame my SIM Card, so i got a new one yesterday, i also did a factory reset just to be sure, DIDN'T HELP.
So to SUM UP:
Issues: Call quality is low in random calls
How does it show: Caller speaks like with a robotic voice, interference, sometimes i don't hear the caller for 2-3 seconds.
ROM STORY:
1. I purchase RN3 Pro. It comes with original china stable ROM. Phonecalls work fine.
2. I install global stable. Phonecalls are fine.
3. I install two updates to global stable - the quality of phonecalls goes down.
4. I unlock bootloader and install custom ROM along with TWRP, same issues.
5. I reflash whole ROM, clean installation, same issues.
6. Yesterday : I get new SIM card, i factory reset my system and get new updates: SAME ISSUES.
Wierd factors:
- sometimes when the problems occurs while on call, i can resolve the issue with just waking up the screen for a couple of seconds..
- problem seems to happen less when WIFI/Data usage are off
- problem seems to happen less when using headphones (Piston V3)
- problem DOESN'T happen AT ALL when i switch to other mobile operator network in roaming! It's only happening in my main mobile operator network! I would use other networks instead of mine but LTE/4G isn't allowed yet while on roaming :/
- this issue happens on both SIM CARD slots, on different SIM CARDS
I tried to reflash China Stable, however it seems that there were too many updates and one of them is causing the problem now on every ROM. There's a few topics on MIUI Official forums about that, there are bug reports about that but i doubt MIUI Devs will notice this.
Does anyone have any idea what could be causing this?
Link to my MIUI topic: http://en.miui.com/thread-267736-1-1.html
Link to random bug report about this from other user: http://en.miui.com/forum.php?mod=viewthread&tid=266620&page=1#pid4845168
Kind regards,
Beliares
hey what happened to your device?
I think my redmi note 3 pro has the same issue, call quality seems to go down where I would lose what the other person is saying for a second or two like the earphone is malfunctioning.
but the speaker works fine and signal is not an issue either
were you able to fix your issue?
I have the same problem with my phone since I remember. I got my phone around 3 weeks ago and flashed the latest Stable and Developer ROMs but the problem still exists. Like mentioned above by my friend, the quality is fine when I change to other operators in 2G, but in 3G and LTE its totally mess. I wish someone recognize this problem and fix this.

so sorry to hear that you have this issue as well
this is just unbelievable.... how can they just ignore such an issue? It's becoming a nuisance to sometimes impossible to use the phone to make or receive calls as I can barely make out what the other person is saying
Is there anyway we can complain about such issues?
Guys I found a workaround for this problem. Although it doesn't solve it completely. By this solution I succeeded making calls with much less noise and problem.
You have to turn the proximity sensor off for calls. It somehow solves the problem for now and make the calls much more understandable. Hope it helps you and get solved completely.
Me also facing same call quality issues

Same here no issues on China stable. Worse on global stable.. try typing *#*#995995#*#* wait 2sec and type *#*#995995#*#*(the same thing)again.. also go to settings installed apps find qti.supersaver open it and force stop these are like temp solution . If this helped please hit the thnx button
Thx for your sharing information but that didn't work dude. The problem still persists.
Guys I got a solution for myself. The problem actually WAS with the signal as I thought contrary. Yes, the 2G network works well because it has more strength with less range so its obviously works better than 3G. Hence, I started searching for a solution to improve the signal I get in my phone. The best thing I found was an app named "Network Signal Speed Booster" which boosts the signal you receive. Whenever I called a phone number after running this app, the call quality was PERFECT. This app actually connects you to the nearest antenna so the result is a better connection to the network provider. Please do this solution yourself and see if it works and notice the others. thx.
Thanks
Behrouz Your solution may work very well for me
I had the same problem
Thanks
My friend has issues with a Redmi Note 3 PRO speaker. He doesn't hear a conversation clearly. The person who he is talking with hears him perfect. Will "Network Signal Speed Booster" app help in this case? Some people says it's a fake program. Any new solutions?
Confirmed, Network Signal Speed Booster helps but temporary. I`ve noticed that it doesn`t matter of the network type,(4g,3g,2g), it happens only while the wifi is on.
Regards,

Doesn't work on Nougat ROMs like Lineage OS
When the wifi is off everything is fine. But I can't understand what causes the issue.

wifi issue

Anyone notice that the xa ultra has some wifi connection issues? For example I'm connected fine and everything and I leave my house and come back.. then it doesn't seem to pick up my home's wifi. I have to restart the phone then it comes back. Anyone else notice this?

Never had that problem.

Every. Single. Day. I leave my house and the wifi won't reconnect at school, or home. I restart my phone and it connects just fine. When I'm at school it won't connect until I restart, and then it connects there fine as well. It would be interesting to see what variables between locations has cause/effect on the connection. I'll do some analysis when I have time, see if there is a time variable associated, like if it happens right away or takes time for the problem to occur. I have a feeling it's related to the cheap parts that Sony used, not sure what wifi chip is installed.
yeah I haven't had this issue yet either. Have an apple airport router. I have only had the phone a week but no problems.
OK it just now happened, (wifi won't connect) and I realized it was just connected when I was inside a building at school without cell reception. I put the phone into airplane mode, then turned on wifi, and sure enough the wifi connected. I'm thinking interference or lack of power is preventing wifi when a medium strength LTE signal is connected. I'll keep testing scenarios that fit this theory.
Just a quick update. It seems putting the phone in airplane mode, then manually turning on wifi only, the wifi connects immediately. Turn airplane mode off, wifi stays connected. No need to restart. Wifi drops on me several times a day and this is my fix. This fix did not work 1 time out of the past 20, and I had to restart.
Mine has been doing the same thing.... ugh Sony can't get their crap right no matter what they do. Dear God.
Anyone else having issues with auto brightness not working properly as well?

No problem here on the normal xa mine is a F3111 LTE model WiFi works and connects great on all Firmwares. Have you tried the software repair option via Xperia companion? If it's still the same after this, you need to take a log using the built in logging application and send the logs via Sony support forum it gives you instructions on how to do it in settings think one of the guys names is Richard, about phone, diagnostics, advanced logging they've actually been pretty good regarding any bugs and fix them once they have some logs to work from.

Thanks for the reply and suggestion. Unfortunately, the repair option didn't solve the issue. After Googling it, it appears many users with the 3213 model are having the same issues. Ugh.
I did not know about the "diagnostics" feature. I enabled it and then it auto uploaded and then turned off. So does support email you or Richard gentleman contact me via the phone somehow to give feedback?
Thanks!

As far as I know it's all done through a pm(message) through the Sony support forum. Then they pass it on to the software peep's and then wait for the fix it may take more than one person to provide the logs before they sanction the update unless they find a bigger problem.

Xa ultra wifi
Here's a funny thing, as long as I am not connected to Bluetooth, WiFi works flawlessly, weird.....
I'm just going to assume we have no fix for this yet? the whole resetting my phone is getting really tiring. blah I wish Sony would fix this or at least acknowledge it
I have the same problem with my XA. I've only had the phone a few days and I'm always having to switch it off and back on. SOOOOO annoying. The guy that sold it me said I could just return it. I'm not buying Sony ever again!!!!!
Been having to use my 4g at home alot of the time, which is eating up my data something rotten. It shows the WiFi is on and has full signal, but it's often so slow or even worse dead! I've honestly had 2g on a crap old phone work faster than WiFi at times. I have just "forgotten" all saved WiFi networks and signed into my home WiFi from scratch and put the password in again. Seems to have done the trick, but I'm not holding my breath that it's gonna last.
I'm curious, it might be insignificant, but just wondering what WiFi service providers all of us with problems have? I have BT infinity. For a while I thought that maybe it was just BT being rubbish. But my partner has a Samsung galaxy s8+ and she doesn't seem to have any issues. I've used the WiFi on my linx tablet, no issues. The Xbox one doesn't really lag either.
So it's either that this phone does not like BT or its just my phone being pants!!! Doing my head in, I have to keep getting my partner to send me extra data.
It's seriously getting on my nerves now

This is my first Sony Android phone, and I'm not touching one ever again.. What's worse for me is that mine is still on Sept 2016 update and my carrier locked the bootloader so I couldn't update it myself, as my network don't even care if I have the latest security updates or not
