Front Camera defect?

Hello,
anyone know the problem with REDMI 2 2014813, that the front cam doesn't work. The CAM-App don't find the front-Cam (Selfie). Someone a idea? Someone know a german service?
I tested every global and chinese Firmware. I had it on service in CZ and it work shortly with the stable 7.1.1 firmware but I had a extrem battery drain by bluetooth. So I want reflash the global 7.1.1. But the result no mobile data connection, and no german language.
Can someone help me.
Thank you!

My XT1570 is recognized as XT1575 and is out of service all time.

Model: XT1570 China Dual Sim (using only 1 sim)
Carrier: China Telecom 4G
ROM: DU Official V10.6 (latest)
I have had great signals when I was on previous DU builds (Mashmallow) but the signal became unstable (completely on and off) on the latest build.
I tried changing a few options not knowing what they actually do in "Settings"->"Mobile". There was an option I can't remember but it seems I changed it from "automatic" to "home only". Since then my phone has been out of service forever. And this option has also disappeared from the "Mobile" submenu too.
I also noticed that my phone model in the info shows XT1575 instead of XT1570.
I guess I first need to make the phone to realize what model it actually is?

i recently heard that Chinese variant by default doesn't ship with *ANY* Google services. In fact, last time I checked, entire Google Service Framework is missing
do return to stock and ull get signal back

I flash a customized rom just to use google. So flashing back to stock is not my solution.
But I had used the DU rom for several months and all have worked well. So I think there is way to get it to work without using stock rom.

Can't you just roll back to an older version of DU and stay there until you can get the devs of DU to look at it?
In general, the Chinese models are identical to asian models, just without Google... Can't you just flash a gapps package on the stock ROM?

Redmi 3s Prime data speed dropping to E and G

Hi all,
I have bought a Redmi 3s Prime last week. One problem I am facing is that if you turn on data services, if it is idling, speed drops to E and even G. The only way to get it back is to manually change network preference type from settings. What could be the problem? Is it a hardware issue?
Android version 6.0.1
MIUI version 8.2.5.0 (MALMIDL)
Please help.

This is a known issue.
Is you have root, try to install Networl Signal Guru, then disable Edge (2g) frequencies.
Some people solve it using a second sim...

Second SIM even if dummy one will solve this problem, I'm using this option and managing my 32GB wisely as you will lose your sdcard slot. Nothing terrible for me as I need it the 2nd SIM anyways.
slds,

Your problem is well known, but still no solution from xiaomi.
Best i can suggest is that u check which frequencies your carrier uses.
If u got root, install Network Signal Guru.
Try disabling one of used WCDMA frequencies and then force 3G. if it doesnt work, try to disable the other frequencies
IT WORKED FOR ME D

Switch to global dev rom you will get the latest one. Miui 9 v 7.9.8
Better you make clean install with MiFlashTool via EDL.
Search fastboot rom here.

Installing a x720 rom into x727 works??

I have a x727 and there are many x720 roms. Can I install it without problems? The devices are almost the same ....

Depends on the ROM. Omni, AICP, Lineage, and RR all work on x727. MIUI I think tends to have some issues on x727 and EUI 5.9 (x720 stock ROMs) have no WiFi calling for T-Mobile US but aside from that work.
EDIT: Don't flash the JUI ROM on x727 that messes up a lot of stuff.

It has issues even if you change the modem firmware to the correct one after flashing the rom? EUI has problems only with T-Mobile? I live in Brazil so no problem for me.. Maybe you didn't put the right modem...
Lucky that I asked this cause I'm planning to buy a Le Pro 3 but sadly the x720 is out of stock
MIUI is my main concern.. what issues specifically it has? Thanks!

Phone fails to pass security check because it cannot detect an IMEI for Sim slot 2 (which the x727 doesn't have.) You'll be nagged almost every minute or so by an annoying pop up.

Ah ok.. so I won't mess with x720 roms.. That security check I don't know how to bypass.. :crying:
Maybe a single file change would do the trick?

You might be able to pass it if you set persist.radio.multisim.config=NA from persist.radio.multisim.config=dsds via Build.prop edit.

Yeaaaah.. I've seen this in some ROM post... It could be mandatory to have in any ROM post IMHO.. So making this change in build.prop any x720 rom may fit in x727
How do I proceed? Do I install the rom and BEFORE it reboots the first time I edit the build.prop in TWRP?? Or I boot the first time and configure the rom (probably without signals) ??

baseband version !!

Hello
Greetings to all
I have a problem with cell signal
My device is one plus 7t pro mclaren (4g) same as oneplus 7t pro
The problem is with it only .. I have another device with the same operator that does not have the same problem (note 10 plus) 4g
This problem was not present when I bought the device ... but now it is
I am currently researching the root causes of this problem and I expect it may be related to the modem
So I have a question?
What is your baseband version ?
My is global HD1913 10.0.9.HD01AA:
baseband is :
MPSS.HE.1.0.C11.1-00007-SM8150_GEN_PACK-2.275114.1.285971.2

You tell us you have a problem but you didn't specify what kind of problem... You have poor signal or nothing at all? You already flashed anything or is pure stock device?
