the new sim card arrived today.
Got it registered, and it jumped onto band 20. Everything looked fine for 2 or 3 minutes.
Unfortunately, it then jumped back to band 3, and hence my issue wasn't caused by the old sim card.
So, yes, it might still be a (general) operator problem, a...
As soon as the phone is jumping onto Band 1 or Band 3 instead of Band 20 the performance goes down the drain again.
When the phone is connected via Band 20 everything is fine... But it switches back ti Band 1 or 3 randomly, even while sitting in the spot on my desk.
Do you know how I could...
This is what they say on their website:
"Along with other software, apps and firmware modifications, on mi -globe. com we provide a complete ROM called “globeROM“, which is based on the official Xiaomi MIUI firmware. According to the official Xiaomi update plan, we always provide the latest...
Hey cobben & Kelpchark,
Even without the new simcard arriving in 3 days time, my Mi8 all of a sudden works like it should.
So much to the roms of this forum :-(
With the rom/link I posted above the sim card's and the dual sim cards' performance are just fine.
Good night & enjoy the remaining...
..in the meantime, you might want to try this rom:

(remove the 5 space tabs in the above link) :)
It works a bit better for me than the eu.community's roms...
Enable expert settings and chose your option...
Fortunately, my Mi8 hasn't seen the sea yet ;-)
The phone is obviously only a few weeks old, and always sat in a protective rubber case.
There cannot be any corrosion inside, yet.
(And the chance to break the rear glass cover of the Mi8 - while opening it - is quite high. Luckily, we can...
I am also having (massive) difficulties with Dual Sim performance.
Apart from a very nice and interessting discussion with another member, I received NO answer, NO comment and NO help from the so called 'developers'.
By now, I also realized that even with only 1 sim card, the Mi8 has a lousy...
On my Mi8, updating the firmware (on top of flashing the latest eu.beta.rom) helped quite a bit to improve the dual sim network performance.
However, I still experience weak and even no network receptions in areas where there are a very strong signals available.
...Like you said, it's hopefully...
Very Interesting and absolutely supporting the idea, that only a firmware update is providing a stable dual sim card functionality for the Mi8 'global version'.
After trying these two firmware versions (with the current beta rom version xiaomi.eu_multi_MI8_8.11.15_v10-9.zip):
... The problems returned :-(
I found yshalgar firmware on XDA here:
But I am to much an amateur to succeed in installing them via TWRP.
What do I have to do in TWRP in order to get the firmware...
Finally SOLVED :)
I completely stripped and wiped my MI8, flashed the original Xiaomi Global ROM (which didn't really work that well due to the Anti Roll Back protection. It booted up and launched MIUI, but then complained about the file system being not encrypted and only offering "reset...
Thanks for the update.
My Mi8 flashed and re-booted like a charm.
1) Slow motion works. However, it seems to work only for the the last quarter of a mini-video with a duration of what, 3 seconds?
--> So the slow motion video sequence records and lasts only for less than a second.
LOL ... So I guess Xiaomi needs to improve their software for "the powerful AI computing capability of the Snapdragon 845 ... to switch antennas more intelligently, thus ensuring signal strength." ... :emoji_innocent:
... In a city with very strong signal quality of the network providers (Telefonica o2 & German Telekom D1).
We have mobile telephone masts all around us :)
I have actually tried a third sim card by Vodafone (D2). Again, according to the official network coverage map it's got excellent signal...
Thanx mate! That's interessting..
A smart phone (even a 'Phablet') still remains a cell phone, and the 'phone part' of the device should still work reliably, especially for emergency calls. Besides, without a stable network reception, users cannot reliably use the mobile data connections for...
