[Q] weak signal, dual-boot, and battery life

Hello I just bought the phone on 27 September and I have 3 questions :
1. is it normal for signal to be weak from time to time? 3g mostly and sometimes 2g as well.
2. how do I do dual boot?
Steps i did : Backup miui (didn't find where the backup was so i could transfer it to PC), then enable true dual boot, everything was gone even in internal memory and i couldn't mount usb to pc in CWM, luckily i have a usb OTG , and i installed slimkat to system one after doing a wipe, then i booted to system 2 and was shocked that miui started with the setup from slimkat and then the launcher started and i was in MiUi, but everything was bugged, i kept getting FC of all kind of stuff. so i checked the internal memory, nothing was there, then i got mad, downloaded official stable rom v23, put it on a usb drive, went to CWM disabled true dual boot, formated data cache and system for system 1 and 2, then i installed from usb flash the miui.
Question is, how do i make a normal dual boot without FC and everything running smoothly. I have CWM recovery v 6.0.5.0
3. How is the battery life? What software are you using and what apps.
Thanks!

ok, so i found out how to dual boot properly, it remains only 1 and 3 questions

Does your M3 WCDMA version or CDMA version? The signal with Xiaomi mobile always weakly, Its normal. especially of the CDMA/WCDMA version.
About Battery life, 7-10 hours is ok. If your phone more than 10hours,that's perfect.

i have the WCDMA version, today i got a sms from Orange saying that i missed a phone call 3 hours ago :/ wtf.. :/ im scared man.. i got 25 more days to send it back and get my refund ..i dont want to have a defective unit
how do u achieve 6-7 hours of screen time?

Mi 8 does not turn off or reboot after some hours turned on

I'm having the same problem in all versions. After running on the phone some hours, if you try to reset or power off the phone, it doesn't turn off at all. The screen goes off but the phone is still on. It keeps working. It can be tested turning on flashlight and powering off or resetting it, the flashlight doesn't turn off. It does not turn on again until you force reset by pressing a while the power button. I think it's related to the GPS problem, after some hours the GPS stops working, and this problem also appears.

Looks like I have the same problem.

I think its a firmware issue, because I'm not the only one affected by this problem. Two friends on miui 9 and me on miui 10...

Nvm got the same bug.

I've installed with miflash latest miui 10 global beta, ant the problem is still here. I've found this problem only when gps stops working

I just noticed that I have the same problem.
If I want to reboot the phone after a few hours he won't reboot and the screen stays black very annoying problem.

Same problem with last miui 10 eu

Dont have this problem on official global beta miui 8.8.7, sounds like software related issue to me rather than a hardware problem;

Yes, I think this because before unlock the bootloader and flash the miui 10 Eu i dont have this problem

Seems that this problem is fixed with the last miui 10 Eu 8.8.9

I have now this version and the problem is there again... installed with miflash. 8.8.7 is still buggy with GPS and reboot. Let's see 8.8.9...

Xiaomi.eu has noticed this problem on their latest version too: https://forum.xda-developers.com/mi-8/how-to/rom-miui-10-8-8-9-xiaomi-eu-t3827802 (see changelog)

Hello guys, I'm facing this problem too on MIUI Global Stable 9.6.4.0, I reported the issue on MIUI forum, it would be great if you could kindly confirm my bug report to obtain more attention. Thank you. http://en.miui.com/thread-3726710-1-1.html

Mi A2 Freezing

Every time i enable camera2api ( including temp root ) my phone become leggy and freezes on different intervals with different apps. But after flashing factory image with unlock boot loader , the phone becomes better .
I tried 3 times and m observing it since jan 1st.
i am facing this problem only with Mi A2 4GB ram variant and before this i was using 6GB variant and never faced such prob, as i enabled and disabled camera2api several times on my Mi A2 6GB .
Kindly anyone can explain , what is actually going wrong or m doing wrong that after enabling camera2api , why my phone freezes ?
Is this a ram related or because of two model of eMMc memory for A2 , i am facing this issue ?
Thanks in advance .

Changing original Xiaomi Mi Max 2 to a custom rom

I have an original Xiaomi Mi Max 2 (Android Version: 7.1.1, Build: NMF26F) with all the Xiaomi updates. Since the phone doesn't get updates anymore, I am looking for a solution to get a custom rom with security updates.
I am searching for a custom rom too, which does not need GPS for Wifi-SSID. With my mi Mi Max 3 and Android 10, GPS (saving doesn't exist anymore) GPS must be activated to see the SSID and I am forced to use LTE, while I want 2G (setting is lost after a restart)
So maybe a ROM based on Android 9 makes sense?
Please point me to a link how to "open" the original phone, so I can flash a custom rom. Does the official way work with the Max2? I have a very old PC, but with Windows 10 20H2 for flashing, normally I use a linux pc.
I am happy if you can help me how to start.

First,TWRP.
Then,https://androidfilehost.com/?w=files&flid=315788 for warm up.

You can try unlocking bootloader and installing Weekly ROM or EliteRom(which I am using).
For better battery life and overheating you can root and install undercklocking modules that are available on this forum ( I am using "SD778G Gaming" module)
