Signal problem - Xiaomi Mi Mix 2 Questions & Answers

Hello guys,
I just bought a mi mix 2, and 2 days it had no problem, but yesterday it had no signal and a restart did the trick. The second time, the restart+reset the phone didnt fix it, so i was helpless until the 9.6.1 global stable came after reset and it fixed the signal/call problem.
Another thing, in the first part of the problem i had no signal, after that i had signal but i couldnt make calls.
Do you think its a software problem or hardware? or it could have been a signal problem from the company i have the sim?

It sounds like your network settings might not be configured correctly. I would find the APN settings that your carrier recommends and see if they are the same that the phone is using. You might also want to contact your carrier and verify that your new phone shows up properly on their end.

The APN is corect, i looked online. I will try to make a phone call to them and see what`s up.
Anyway after the 9.6.1 stable global, the problem fixed(i hope).
I was asking if anyone has ecountered this bug/problme on their phone.

This problem has occurred with some users when the network settings aren't set correctly. Mine defaults to gsm/td-scdma/lte instead of gsm/wcdma/lte. Use *#*#4636#*#* to double check whenever you reboot your phone.

Scroll up when you enter the menu and it's there. Or are you saying that you have the only Xiaomi where the option isn't available?

It's not a question of better or worse. The setting you have is for China. Just change it on both sims and it should work.

So far so good, but i didnt leave the city like last time when the signal went dark. So i hope its ok even when i will leave.
one more question, after each restart i have to put it back again, right?its the same at you too?

Yes. You have to reset it after every reboot.

"My phone number" in Call Settings

Hey everyone. I have to reenter my phone number every few hours because it doesn't "stick". Anyone else experiencing this problem? I'm wondering if it's phone or rom related. Thanks.

Care to share?
Short answer is no, I've not seen this problem whilst trawling the forum. Have you created a profile in your Google account?
Really need more info: country, ROM, Radio, Network etc.
Has it always done it or recent? Have you changed something that seems to coincide? Have you tried a hard reset?

i just noticed it. i have no idea how long it's been going on. i've changed the rom/radio a few times already so it's hard to pinpoint which change could have caused it. and yes, i've tried a hard reset.
Figured out what's causing this. Everytime the phone is placed in airplane mode, the phone number gets erased.
Sent from my DHD
Apologies for not getting back to you.
That is strange. Glad you found the cause but it's still a bug. I have the same ROM and Radio and don't have this issue.
Would still like to know the proper cause of this.
Does it lose the number if you reboot the phone?
Just for curiosity, could you put the phone in airplane mode then if again after an hour the number still doesn't return, go to settings -> wireless & network-> mobile networks -> network operators
Let it do it's thing for a minute or two (searching) and then select your network from the list. Then check to see if your number has returned?
It really is a curiosity thing. Sorry I can't be more help.

[Q] Can't make 3G work on another carrier (SOLVED)

When add settings of my carrier in DFS (cdmatool), it is not saves them. Who can help what can it be. Or it is just need to enter right APN settings? I'm new in this. Sorry for bad English. May be some one know what I'm doing wrong. Please give me advice.
Solution:
- as it turns out you need to put zeros in line 39939 (NV Items -> 39939 | NV_LG_DATA_PPP_CARRIER_I | User | - - | 1 | 2byte), than do everything like described in DFS. Also 3G Rev B works well (DFS -> tab Data -> mode -> RevB_MFPA)
:victory:

I never used DFS.. But from what I remember from way back..
After adding the ESN to your carrier
I would flash the prl and activate the phone...
If the Internet wouldn't work... Then I would need to manually enter the APN settings.
Never did and LTE phones though..

I'm afraid that won't work either. The phones EFS won't let the manual write stick and I can't figure out why either. I've been trying since I've had the phone. I have mine flashed to Verizon but only 1X. I was looking at the thread on backing up this phones EFS to you computer and was wondering if I could be backed-up and changed while on a PC then copied over the existing EFS. I don't have time to try it right now so if anyone else does give it a "go" and let the rest of us know if it works.

I hope you are able to figure out how they did it soon because I can't stand having a [email protected]#$$$ paper-weight. LOL. By the way, after I flashed mine, one of the main bugs is the "hands free activation" notice that pops up every time it gets turned on or up from sleep mode. Is there a way to delete the file that controls this or at least permanently turn it off?

The hands free activation is an app that runs automatically at startup. You can remove it from /system/app/OmaDmclient.apk or uninstall "Update Device" with Titanium Backup.
Sprint likes to change up the app in its devices, but it seems to have the common thread of "omadm" in the apk name.
Hope that helps.

Unable to login to whatsapp, wechat and line but still can use facebook search engine

I am using Note 2 N7105 and was previously using the clean rom and had no problems earlier.
I flashed **[4.3][CM10.2][06.10]Team Asylum CM10.2 - Slim, Fast and Black Roma™** and soon start to have below mentioned problems.. I was advised by the developer that it is not a rom specific problem..
I realise I couldnt send or receive msg from whatsapp, wechat, LINE and other social messaging apps using 3g/4g connection but I could still use google search engine, facebook, google map etc. Wechat shows "Server access failure (1,237)".
I uninstalled and tried to reinstall the social messaging apps using 3g/4g connection, Play store shows an error of 413. however I could reinstall using wifi.
There is no problem with the social messaging apps when I use wifi.
I have tried a full wipe, restoring back to my Clean rom, change to other roms, reinstalling them. but I couldnt resolve the problem.
I am now currently using [ROM][10/05/13][4.3]BeanStalk 4.3.1001..
Can someone help?
Can someone help? It is urgent as I couldn't receive any msg

ok, sorry i couldn't help, but it's definitely a software issue, so try a stock ROM and check if issue persists, I have nothing else
But it shouldn't be a ROM problem.. I tried many ROMs but it remains the same

For me I can't upload greetings to facebook by splanner, for friends birthdays. Sad and annoying situation and this is happend after I rooted my galaxy and installed custom rom. So I think it's related with rom and rooting, how and why have no idea.
APN Setting?
Sounds like it's your APN settings. Had something similar with 4.3.
Most network providers have a webpage that will automatically send the correct APN settings by text. Try that. If not, call them and ask them to send them out. Think it's a proxy problem caused by incorrect settings.
Hi mate, I am afraid we don't have the same problem. Appreciate if u could start a new thread yourself as the advice provided will be messy, not sure for you or for me.. thanks...

Smart Settings - My Place greyed out

Hi,
I have recently tried to figure out the Smart Lock Feature of the brand new LG G4 smartphone.
However I was not yet able to find any working solution to this problem.
Does anybody came across this problem?
Thanks
Same issue here..
You have to set it to high accuracy.
Thanks for the replies. However, I have set it to the high accuracy - see the picture.
Any other suggestions?

Same issue here. Mine is also grayed out. I've tried many ways to solve it but in vain. I am going to try jerflash's manner. It is indeed very strange!
I really wish this worked via Wifi networks. Mark X wifi network as home, and Y wifi network as work. I dont run GPS unless I need to. But it would be nice to have things toggle based off wifi or even just a general location. My work and home are 50mi apart, phone should be able to tell where I am haha

I've solved this problem!!!
Someone told me that "my place" can be only set on while using mobile network. If you use Wifi, "my place" can not be set on. This works with me! So happy I finally can turn on "my place" and use the smart setting. Hope this also works with you. Good luck! :good:
Oh, well, thank you. This fixed the problem. Thank you so much!
For anyone who comes here from a search: LG phones with Smart Settings only seem to work if mobile data are enabled. So if you have limited data allowance and keep mobile data normally disabled, you're out of luck.

Unable to change Mobile network (provider) [OnePlus 2 - LOS 16.0]

Heya everyone,
I am unable to change mobile network providers.
I try to disable "Automatically select network" to change my provider manually.
An error occurs:
Couldn't find networks. Try again.

When enabling the slider again, the following appears:
Already in automatic selection.

(when I don't re-enable the slider, but rather back out of the menu and go in again, the slider is enabled by itself)
Has anyone ever run into the same problem or got an idea what could cause the problem?
Any help and ideas are very much appreciated.
Push? :crying:
Maybe it depends on the country and SIM card Provider? I have the same issue and cannot select Network Manually, would need to do so cause this SIM card is new and just roaming cause its US card used in Europe, how to force a command line Network scan? Moreover I had this issue in 15.1, too. N910V Verizon Note 4

I guess I didn't reply instantly back then and just forgot it.
I just now saw it in the subscribed threads.
My apologies.
Well, the updates on this may come a bit late, but with LOS17.1 (Android 10) I'm not able to reproduce this problem.
If you haven't already, I can greatly advice to upgrade!
