DSFA Chinese phones - General Questions and Answers

Can anyone advise on a Chinese phone that supports DSFA (Dual SIM Full Active) ?

Software customization
Can you customize a phone in order to make it Full Active?
As I've seen on many sites, almost all the phones are promoted as DSDS (Dual SIM Dual StandBy). However, it seems some are really DSFA!
Thanks!

One DSFA phone is Lenovo Vibe X2. When one sim is busy the other is active. I use it and so i know for sure

No you can not do it because dual full active require 2 trasmiting modems. The dual sim stand by uses one and for that reason when you are talking in one line the other is turn off.
Asus Zenfone 2 551ml DSFA (4GB ram, Intel CPU, up to 256gb storage and 5.5" screen).
This is the only dual sim full active that the WW version supports LTE band 20 at 800Mhz that is important for 4G coverage in europe.

The last Huawei phone that is DSFA is mate 8. What a pity
Send by Huawei Mate 8 (NXT-L29)

LTE, stock(ish) Android, dual sim, Chinese brand?

I'm looking for a dual sim phone which supports LTE, but with as close to stock AOSP as possible and also with reasonably hi specs.
I know I could go down the S5 or HTC M8 route and I guess they are options.
I have however been looking at some of the Chinese manufacturers which are presently offering some very good speced dual sim LTE phones, namely the Honor 6, Elephone P3000s and the Nubia Z7 mini. My biggest issue with these though is rom support and whether they contain GAPPS (and also how rootable they are).
Reading around it seems that the Nubia Z7 mini might be the best supported in terms of Rom (both officially and unofficially).
I am seriously tempted by the Elephone P3000s (when it comes in stock) mainly because of the price as well.
Any other thoughts, or options I'm missing out on?

Single sim tray from OnePlus?

I ordered my 7 Pro (GM 1917) directly from OnePlus website. Nebula blue 12 - 256 version. When I installed my Verizon sim card, the tray only had one slot? My 6T has dual slots and my 7 Pro software indicates the dual sim options. I'm confused. Do others that purchased the non-T-mobile 7 Pro have a dual or only a single sim tray???

I believe the T-Mobile variant comes with a single sim tray your version should have the dual SIM card

The other sim slot is on the back side of the tray. It does not have two side by side like before. They are front and back.

One directly from OP is dual sim and the other sim goes on the other side of the tray. I was confused for a few seconds at first but figured it out. Dual sided tray vs a bigger tray that holds 2 sims on the same axis.
Check this video showing new sim tray from 2:08 forwards.

DOH! thanks so much! I guess I was so excited to get my sim card in and get up n running I didn't really pay much attention to the design of the tray.

Huawei Mate 9 Motherboard replacement

Hi,
I have a damaged Huawei Mate 9 64GB Dual SIM (MHA-L29). The phone needs to replace motherboard, which is not easy to find.
I have two questions:
1- Is it possible to use motherboard of Mate 9 Pro (LON-L29C) instead of (MHA-L29)? Probably not possible!
2- Is it possible to use motherboard of Mate 9 Single sim Card (MHA-L09) instead of Dual sim card (MHA-L29)?
Thanks in advance
To answer those questions:
1) My thought would be no, based on if the motherboard layouts are different. Maybe check out a few teardown views of both models to see.
2) I dont think the single sim version would work because the SIM tray for the Dual version is longer, so when you swap the board, it wont have enough space to fit the dual slots.

Option 2 should work, actually I remember that I read here about people rebranding (by changing the firmware and SIM tray only) single SIM Mate 9 to dual SIM Mate 9 - therefore, differences are only in firmware and SIM tray
Search on the net and here on XDA and you will find more reports and discussions like this:
https://forum.xda-developers.com/mate-9/help/mate-9-single-sim-to-dual-sim-t3596158
It was also possible to rebrand single SIM to dual SIM for some other Huawei models, like P9 Lite (but not P9) and I think P10 (used to be long ago when those phones were hot, when unlocking Bootloaders were easy and I was actively monitoring the threads here about)

Outer dimensions of single and dual SIM trays are the same, they only differ by the internal cut-off of the first slot (on the single tray it can accommodate only SD card, on the dual tray it can accommodate either SD card or nano SIM)
Longevity of that first slot depends on the longevity of SD card. Nano sim is smaller and it goes turned by 90 degrees (parallel to the nano SIM in the second, SIM only slot). Hence there is no need for that combo slot (and the whole tray) to be longer - just the hole in that first, combo slot has different shape to let also the nano SIM to settle in)
You can search on e.g. eBay, Amazon or Alibaba for the spare parts, SIM trays and compare their shape and size (and compatibility notes - e g. some dual SIM trays are denoted as fitting also to the single SIM Mate 9 models)

Thank you for the guidance this is really helpful.
I didn't think option 1 would work, my concern with option 2 was the sim card tray size, your explanation about outer dimensions and internal design of the sim tray is exactly what I was looking for.
I checked on Aliexpress and ebay for sim tray spare parts, and I was surprsed that everybody is using the dual sim tray instead of the single tray! It is making sense as it can work for both not vise versa.
I will buy the MHA-L09 motherboard and go ahead, I don't really mind using one sim, I just need to turn life to the dead phone.
Thanks for your help.

realme x50 pro 5G - Dual Sim

Hi All,
i've just taken delivery of my Realme X50 Pro phone and cant figure out the 2nd sim,
i have searched online and see plenty mentioned about dual sim capability, but i'm pretty certain this doesnt have the 2nd sim slot, it has bars across where the 2nd sim would go.
i bought it from laptops direct and it didnt mention whether it was single or dual sim, i assumed it was dual sim as all information online pointed to them being dual sim, i have the 12gb 256gb hdd option.
do you know if it is possible to add dual sim functionality similar to that of the old Huwawei p10 plus?
unfortunately because i have opened the packaging i cannot return the phone.
i have the same prplm
