"Phone" and "Wi-fi" problem

hello xda
ive been reading these forums for a while checking out tweaks, software and other stuff, good stuff
but last night, when I wanted to check out my email, i turned on the wifi but after a few seconds, the wifi slider would go back to "off", i did a reboot and the problem persisted. meanwhile i noticed the "phone" was off too, so i tried enabling that too, no luck, same thing.
and something else too, after like 3-5mins of using it, the touchscreen crashes and i cant use it anymore, only buttons will work.
today i decided to do a hard reset, but that didnt fix anything. when i go to "communications" panel, everything is "off" except Bluetooth.
-if i turn that off, airplane mode goes on
-if i click phone on, it goes off after like 5 seconds, same with wifi
has anyone else experienced something like this ?
thanks in advance,
xerron

[Q] Stuck on Flight Mode ON - No Wifi, No Bluetooth, No Cellnetwork

I dropped my phone in the water. Got the battery out quickly and opened up the phone from A to Z (except the circuitry under the screen) and got it dry, left it to dry for 48 hours on top.
Now, my phone is back together and it boots, screen works, sound works, OS works.
But the phone is always in Airplane mode when I boot it. If I try to change the Airplane Mode to Off from the menu shown while pressing Power, it says it turned it Off, but it's then greyed out (can't turn it On and says its off). If I go in the Settings in Wireless settings, Flight mode is still on. If I try to turn it Off from there, it says, turning on wireless things.. but stays there.. If i go <-back and go back into Wireless settings, flight mode is still On. If I go in Wifi settings, the wifi is off, if I select it to be on, it starts scanning and eventually says: Unable to scan networks.
So, I'm wondering, what part is busted ? Anyone know ? My connections seem to be OK, I've put it back as it was. I'm basically bummed.
Also, in settings-status my IMEI is unknown and pretty much everything relating to connectivity. USB works though.
Any ideas? tricks ? anything ? other than buying a new phone to replace this one.
Cheers.

Having troubles with my phone, please help!

So, my phone seems to have commited seppuku.
I'd modded it with CM 12.1 and a couple of Xposed modules, and it has been working flawlessly until this afternoon.
After coming back from lunch, I pickup my phone to check on notifications, but the screen seems unresponsive, no matter what I'd do, it would stay black. I tried mashing the power button, volume, nothing. At all.
So I forced a reboot by holding the power button for 10 seconds or so, and it just wouldn't go past the bootloader warning, I tried rebooting several times already and even tried going into TWRP recovery, but it would just get stuck loading, never showing the interface..
So then, after a while googling, i found this thread and I got back to stock Lollipop 5.0.2. But now the problem is that the phone refuses to use my SIM cards, it detected both of them and named the first one.
I've got no phone service, no data service, nothing at all. The weird thing is that when I try to make a phone call it tells me that I must disable airplane mode before doing so (which I obviously have disabled, no reason for me to enable it). I tried enabling airplane mode, disabling it again, enabling it then rebooting, then disabling it... nothing has worked so far. I've dug into the the phone settings as well without success.
I don't know what to do, I'm out of options... Someone please help me

Screen not working after some minutes

Hi everyone I've got a big problem with my wife's Mi 5. After some minutes/hours of usage the touchscreen stops working and the only solution the make it work again is to reboot the phone (by keeping the power off button pressed).
I've tried some rom (MIUI stable, MIUI dev, Paranoid Android 7.3.0) but all of them have the same problem, someone has got the same issue?
I think it's not only an hardware problem because the touchscreen works most of the time... Any ideas?
I'm having the exact same problem with my wife's Mi5 too. I thought she was talking rubbish until I started using the phone full time over the past few weeks.
Symptoms:
Screen switches on and accepts one touch event.
Screen is then unresponsive to touch events.
All other buttons (home, power, volume) all work OK.
All functions work OK (calling, SMS, etc) via remote control (MyPhoneExplorer)
Screen then becomes responsive again after reboot
Tried so far:
Clearing dalvik/cache
Clean flash - using MiFlash and China dev ROM
Opened phone, cleaned all ZIF connections and reconnected.
It almost feels like something in the touch firmware or driver crashes and does not reconnect - as the phone is clearly usable save for the touch panel.
I'm going to ask Bruno/bgcngm and see if there's anything I can do to try and diagnose the issue.

In my case unresponsive screen to touch events, all phisical button works and the only option to make it works again is to reboot. I didn't try to use it with some "remote" control.

I didn't try to open the phone, but I installed all roms with TWRP and format data/wipe cache/dalvik before.

I also think that it's related with a software issue...

If you need some other information or help I'll give you as much as I can.
Well on my old mi4c i had similar problem. I mean sometimes when i pressed power button and tried to unlock it screen didn't work. For me solution was simply to press power button again to turn off screen and then turn IT on. Maybe this will help u. Have u try that ?

Do you think it's something related with Doze or standby? I think so because today (and yesterday and so on...) I wasn't able to turn off the wake up alarm (the phone was in standby with the screen off all night) with "the screen" but I have to force restart the phone with the button... and it's very annoying.
Maybe we can try with some Marshmallow ROM instead Nougat one.

I'm facing same issue.I've changed my display panels but it doesn't solve my problem.it is quite painfull.i don't know what should i do.
any update sir?
My MI 5 has a different issue. There is no response if I place the phone on the table, but it is fine if I held it. It seems the touch panel is only responsive when the sort of sensors that a human is holding the phone. I have no idea why it starts to happen in these weeks. This symptom happens even in TWRP, so I don't think it is related some particular ROM. Tried firmware 7.7.6 ~ 7.9.22 with no luck.
skip lock screen
Hi
I know I am late to the party, but just faced the same issue yesterday. To bypass the issue, follow the following steps
1. Restart your phone .
2. Enable developer options from about section in settings. (google enable developer options for specifics)
3. In developer options, there is an option to skip screen lock. Enable that.
4. Voila!!
Hope it will help other mi5 users..
Hi,
I had the same problem. I found this video and I tried to fix it. It worked pretty well. Bye
In a situation that I can't do any service for my Mi5 as of now - is this really loose cable thing ?
Can more folks confirm that this cable solution from above video works ?
exactly same symtoms :
Random screen freeze - only option is to reboot phone or phone goes rebooting randomly itself.

Activate device problem

Hello,
yesterday my Redmi 9C NFC lock screen didn't work and the only thing that worked was to turn off the phone, restart it, switch to airplane mode and mute it. So I factory reset it and after booting up I got the activation screen. So I filled in the password, gave the verification code from the SMS, but the phone still remains on the same screen. Does anyone know what to do with it?
Thanks in advance for your response
