I am out US on wifi only and there are a few issues i noticed. Im wondering if anyone else has the same problems.
1) If the phone is restarted it shows a full 4 bars when connected to wifi. Once the phone goes to sleep and has been sitting for a while then when I unlock the screen it says I have one bar and it performs that way. Toggling the wifi on and off has no effect the phone must be restarted to get the signal back strong.
2) The wifi reception overall generally seems weaker on my G than on other devices. In certain areas wife's Galaxy SII and my iPad both have signal of 2 bars and the G has nothing plus my G keeps disconecting from the wifi.
3) Power saving mode when the phone is down to the last 30% it turns off the wifi and turns on the LTE. Shouldnt it be the other way around!
Thx,
Mark
So I've been using cleanrom with no issues until today. I tried to switch to liquid smooth. It only got one or no bars until I made a call, then had 3 or 4. Then went back after 10 or so seconds. Now I tried paranoid android 3.0. Same issue. Tried different modems. APN is identical to stock att.
Any ideas?
Edit: ugh. When I disconnect from wifi it stays at 1 bar until I call, but if I call with wifi off, then disconnect the call and use data, the signal strength stays at max for a few minutes. But if I turn on wifi it goes back to one or zero. Wtf
More edit: I'm thinking an apn setting is messed up somewhere or something. I can see now that when I'm on h+ or 3g I can have full bars, no problem, but as soon as it switches to lte it drops to one or no bars
Edit tres: when I do have a 1 bar 4G signal it is excellent, almost as fast as wifi.

Anyone?
I've had this phone for a few months and it's been working great, except for the last few days. No matter where I am, I have very poor call signal (1 bar). Turning on/off mobile data doesn't seem to effect anything. I can call using wi-fi calling, but of course I need a wi-fi signal in order to do so. Usually if I call someone the call drops instantly or within 10 seconds. Any ideas?
I started having this strange problem about a week ago, in bad reception areas the data signal goes from 3G to edge then the phone restarts by itself, if it is connected at edge then again restarts till it loses the data signal and then the phone works fine. I have to restart the phone to get a data signal. I tried factory reset and I even re-installed the stock firmware but the problem persists, is it related to the Lollipop update? Anybody know a work around it as it is very frustrating.
N.B: Never happens in good 3G reception area
I have the same problem, have you solved it ?

Hi, I have a brand new Poco F3 6GB/128GB running on MIUI 12.5.6.0 Global Stable, and sometimes wifi and/or mobile data drop randomly.
I was just walking home about 30 minutes ago while playing Clash Royale on mobile data, had full signal bar and was on 4G+, then suddenly it lost internet access, 4G+ symbol disappeared, but the full bar of signal still remained for a few seconds before going out of signal, and then suddenly I have full signal bar and 4G+ again. Loss of connectivity lasted for about 15 to 20 seconds.
This happened in a place where I always had 100% coverage, full bar of signal and 4G+ on any phone.
I am using only SIM1, the second slot is not being used.
It has also happened twice on wifi, and on both occasions I was also playing Clash Royale while laying on my bed, then suddenly wifi drops and takes about 5 to 10 seconds to reconnect. I usually get 'Good' signal strength in bed, sometimes at 260Mbps and sometimes at 585Mbps, every other phone I had could maintain a wifi connection to my AP from bed.
Is anyone else having random connectivity drops?
It can be related to: https://forum.xda-developers.com/t/random-reboots-while-using-lte-in-aosp-roms.4330991/

(Same issues)
and unfortunately no fix from xiaomi..
I will be able to unlock the bootloader in about 24 hours, if the .eu ROM does not fix this issue I will return the phone on Monday.

I have a bug ticket submitted to Xiaomi, it's just a matter of time (hopefully) till they provide the modem crash fix! Can you force your mobile to 3g, and see if you can reproduce? I bet you can't..just to confirm that we're having the same issue.

Haha I'm currently very curious whether Xiaomi did such "kernel hack" as well, which just resets the modem rather than forcing the whole system to reboot.
I'm currently on LineageOS with custom kernel, which implements such "kernel hack". To me at least random connection loss is much less bad than random sudden system reboots.

I'm curious what your dmesg will look like, although I'm not a dev myself.

Although I'm also a victim of random modem crashes (and initially it's not only modem crashing, it's the whole system was forced to reboot, until I found the "kernel hack"), honestly I'm not sure whether all these "random signal drop" "random reboots" issues share one common root cause at all. I have no idea it's a software issue (no matter it's kernel driver, firmware, or even some userspace stuff) or a hardware one either.
Besides, wifi and cellular belong to different subsystems, if I'm not mistaken? To be honest I haven't noticed system reboot triggerred by reasons other than "esoc0" (which should be cellular, not wifi?) myself.
I'm using Poco F3 on T-Mobile here in the valley in Southern California. I manually enabled VoLTE and Wi-Fi calling. I have my SIM card in slot 1. I'm on MIUI Global 13.0.2 Stable. Everything is working great, but when I drive to certain low signal areas, the phone switches to 4G and will not switch back to showing VoLTE 5G in the status bar even when I'm back to a great signal area. I have to use airplane mode, or toggle VoLTE setting off and back on to get it to switch back to 5G with VoLTE working again. Any idea if there's a way to permanently fix this issue? I don't know why it switches to 4G and never switches back! Is this possibly related to the modem crashing bug discussed on this thread? I love the phone but this bug is very irritating!
Hello. Im having the same issue. Were you able to fix the issue?
