[Xiaomi 14 Ultra] eng3:
The satellite will only work of you have a china telecom sim. It's designed for chinese people.

Global version doesnt have satellite for that reason (maybe it has the hardware)

As for differences, the CN one is cheaper, more options, bigger battery (and newer technology). To unlock you need to goto a guy, pay him, you remote desktop, let him control your screen to perform the unlock with your phone connected. So the whole thing is sketchy but makes sense with the massive price difference.

Global costs more, has more bands, free to unlock, rom doesnt have china bloat ware to comply with EU regs.

I will plan to install xiaomi.eu rom which will work on either. Google pay and android auto is reported to work with that rom even with unlocked bootloader. I don't think it works on china rom. not sure about Europe rom.

If it wasnt for the bands, I'd buy the CN version for sure.
[Xiaomi 14 Ultra] veimus:
Google Pay works fine on china ROM, Android auto no idea.

xiaomi.eu Google Pay works on unlocked bootloader, however you need to download from time to time Google Pay fix.apk separately.

This is the principle of a satellite.

Developed by the CASC China Academy of Space Technology, the Tiantong 1-03 satellite will network with the Tiantong 1-01 and Tiantong 1-02 satellites. It will improve resource efficiency and service capabilities as well as establish a mobile network with ground facilities, making comprehensive mobile communication services available to users in China and abroad.

Real time satellite tracking for: TIANTONG-1 2

Track satellite(s) TIANTONG-1 2 and see where are they located now. Check when there will be the next pass over your location

Is there any way possible to enable satellite connection in global version? I mean by any way possible, installing the cn rom, buying cn simcard or any other solution ?

Satellite calling

Hi all, Just ordered Chinese version of Mi14 Ultra as it has bigger battery and also satellite calling if I'm not wrong :) Found this video on YT, but don't know exactly if it's work anywhere in the world or only in China ? Time will tell :)...

[Xiaomi 14 Ultra] Rovyo:
Yes im aware of that one and want to order itm but want to know if there is a possibility to enable satellite communications in 14 ultra global version.

(Didn't get the cn version at the end)
[Xiaomi 14 Ultra] NOSS8:
Just like the bands for the Cn version, not possible.
[Xiaomi 14 Ultra] Rovyo:
Ohhh well... Didn't know that sad really sad news
[Xiaomi 14 Ultra] NOSS8:
The Global version remains the best option, unlocking the bootloader will be free and you will have more bands.
[Xiaomi 14 Ultra] Rovyo:
I travel constantly, so i went for more bands choice 😀, bootloader doesnt matter as price is equivalent. Was just hoping for satellite communications as its very life saver during my travels.

Still can't get that regional difference in option. I mean in band why not but the rest. They should stop
[Samsung Galaxy S21 Ultra] mrrobc97:
One UI 6.0, Android 14, Stock ROM, 60Hz screen rate, Vivid screen setting.

So I owned multiple S/Notes and I've never had come across this issue. I purchased a brand new (real) S21 Ultra about 2 weeks ago. Ive been setting it up for my daughter like all her past S phones. During this time I've been noticing that at very low brightness the blacks "wash" out to the point that it looks like an LCD panel instead of AMOLED. Its extremely noticeable in the AOD screen. Why would the leds light up at low brightness to produce a washed out black instead of staying off to produce a "true" black? Also, the dark mode background on any Google app looks greenish instead of a dark gray and the white font looks pinkish. I always use vivid on my display settings and this time I tried adjusting the color settings but nothing. During the boot-up SAMSUNG GALAXY logo everything looks normal and same above 1/3 brightness ( I get the true blacks) but below that the screen starts turns into a old lcd looking screen.

Haven't been here in a minute but I'm having issues trying to search within this forum to see if this has been brought up before so sorry if it has and if so kindly re-direct me please.
[Samsung Galaxy S21 Ultra] blackhawk:
Try running Screen Test on it.

See what you got.
[Samsung Galaxy S21 Ultra] KingFatty:
The screen mode (natural, vivid) was bugged for me when it comes to full color HDR display, and I was able to fix the issue by using ADB to set the phone through all five screen modes (including two 'hidden' modes). I wonder if you could try that and see?

When I did this, I was finally able to see the 'hidden' images in those red HDR test square images, where you can't see the picture hidden in the square unless your screen is showing its full color capability.

Anyway, you might want to try this, where you step through all five screen modes then just set the screen mode back to vivid (or natural) to where you should then enable HDR support.

See here for more info on trying the hidden screen modes:

[Samsung Galaxy S21 Ultra] mrrobc97:
Thank you for the test app!

So I tried it along side my work phone (Note 10+) since my daughter is using my Note 20 Ultra till I'm done optimizing this one. While testing I turned the brightness all the way up and disabled adaptive brightness and also kept both phones on vivid display. What I found is the display on the S21 was definitely brighter and colors more vivid than the N10+ (given the generation gap it should be expected from the S21 Ultra). Gamma was a bit off on the S21 compared to the N10+ and the grays have a more yellowish tint than the "cooler" grays on my N10+ (I do like a "cooler" display). On the black screen (btw tested on a completely dark room) the N10+ was completely black without any trace of illumination as expected from a true AMOLED screen but not for the S21. You can still see a trace of illumination which you probably would notice in a semi-dark room. The real noticeable issues happens at around 40-45% brightness where its supposed to be a true black background but I get a washed out black instead...like looking at a premium LCD screen trying to produce blacks. Extremely noticeable in a very dark room. Also, the switch to a washed out black is not gradual but it happens instantaneous at around the 40-45% brightness I mentioned.

I read of a very few people complaining about a "greenish" tint on their AOD screen so I feel they are experiencing my same issue. I'm not sure if the phone is defective or I got a brand-new pristine looking screen-refurbished phone. Any thoughts BlackHawk??
[Samsung Galaxy S21 Ultra] mrrobc97:
Oh wow! I was unaware of the hidden screen modes. I'm definetly going to try them out. The issue I'm having though has nothing to do with the screen modes though. If you got a minute check out what I replied to BackHawk above and give me your input if you please. Again, thank you very much for the info on the screen modes.
[Samsung Galaxy S21 Ultra] blackhawk:
Interesting. I long suspected that starting with the N20U's variable refresh rate display that color calibration would suffer. From looking at the color throughput using a pro shooting color calibration chart, the N10+ is spot on. It's a killer. Both my N10+'s in spite of the oldest one's age look identical with ScreenTest. That surprised me. It makes the case for almost always keeping brightness below 50% and out of direct sunlight.

As I said before I've seen color "bled" on a dark background in a dark room. That appears to be software or maybe firmware vs hardware. I'm still playing with my two copies to see if there's a difference. Not losing sleep over it.

Samsung knew there be issues with the variable refresh rate displays and color calibration. I loathe Samsung today as they are totally hype driven like the 200mp cam bs and the AI generated images. Samsung should have gone with a fixed 90hz refresh rate and the better color calibration it would have enabled.

Even though the specs look great and the sublime reviews the new Samsung's always get, I call bs. Until Samsung can pull another N10+ out of their assets, they are dead to me.

Obviously there should only be black (off) pixels if that's what the coding calls for. Personally I don't take the AOD screen that seriously but I will scrutinize mine more carefully. This is why... it could be my own eye's vitreous body causing the light scattering🤣

Not everything is Samsung's fault. Seriously change the AOD color to say reddish and see if the black still looks green. I think it could be light scattering of your eyes. This phenomenon is what I attributed it to and never gave it much more thought. I have always found it annoying so I try to ignore it. Mind you I have excellent vision.

I use the tap on only setting so even if there are some pixels on that shouldn't be, the extra power usage be irrelevant.
[Samsung Galaxy S21 Ultra] Dmbruley:
To the original post, I have the exact same issue. I bought an unopened, unlocked S21 Ultra from eBay two months ago. I was skeptical, but it opened like any brand-new phone should. Great. First hurdle cleared. First boot-up and every other boot-up since, the logo is lit up with an otherwise perfectly black screen. When using the phone, dark areas are green and there is banding.
[Samsung Galaxy S21 Ultra] miqu007:
I'm sorry for the inconvenience you're experiencing with your new S21 Ultra. The behavior you're describing, where the blacks appear washed out at very low brightness, is not typical for an AMOLED display. It's possible that there may be a hardware issue with your device, or perhaps a software bug that's causing this problem. Before we explore those possibilities, I recommend checking a few things:

Ensure that your phone's firmware is up-to-date. Go to 'Settings' > 'Software update' and install any pending updates.

Double-check your display settings. Although you mentioned trying various color settings, ensure that 'Vivid' is still selected as it typically provides more saturated colors compared to other modes.

Perform a factory reset. Remember to backup your data first, then go to 'Settings' > 'General management' > 'Reset' > 'Factory data reset.' After the reset, restore your data and check if the issue persists.

If the problem continues after trying these steps, consider contacting Samsung support for further assistance.
[Samsung Galaxy S21 Ultra] blackhawk:
Try changing the wallpaper to complete black.

I've seen horizontal artifact banding (.2 - 1.5 cm thickness) that are visible only in low light caused by the wallpaper.

This isn't a hardware defect but a glitch maybe a coding anomaly.

It's possible if nothing works that the firmware has been corrupted, Single Event Upset. Reflash it. If returnable, do so rather than reflash it.
[Samsung Galaxy S21 Ultra] mrrobc97:
("You can still see a trace of illumination which you probably would notice in a semi-dark room.")

Sorry I meant WOULDN'T.

Also I forgot to mention I keep my refresh rate at static 60Hz. I choose battery life always before gimmiks/animations/prettiness/performance for everything in our phones. I can't remember the last time I had a dead phone...same for my daughter...which is funny that the same friends that tell her to get an iPhone are the same ones she's bailing out when their phone dies and she's letting them charge their phones using the wireless power sharing funtion in her phone.

I absolutely don't use the AOD function as well (again, battery life) BUT the thing is I'm pretty old school and I liked having the notification LED back in the older Samsung phones. On these newer phones I like using AOD Notify which you can either have a dot or a circle (my preferred choice) around your front camera and you can have it set up to just the circle itself lights up on your screen when receiving a notification. That works via the AOD function which the app turns it on just when you receive a notification and switches back off when the notification gets removed. No other information gets displayed on your "off" screen besides the actual blinking circle so it acts like a notification LED. So in theory and actual use (confirmed on my N10+ and N20U) every LED in the screen is completely off besides the ones lighting up the circle.

Well the problem on this phone is that the entire screen lights up with that washed out black background along with the notification circle. If I leave it like that then that means every single LED in the screen is being lit up instead of just the ones for the circle. That would definetly kill the battery if the notification is left unnoticed. Unfortunately I didn't noticed the screen issue until I was setting up this app. I haven't added a screen protector yet so is the pure screen. I can't say is light scattering I see since I used my pitch black closet to inspect this issue.

I'm kinda stuck with the phone now so really would like to verify if this issue was caused by a refurbished cheap-ass non-samsung screen so I can see how much (and if its worth it) is to replace it with an actual Samsung one. Is updated to the latest firmware and all settings are identical to all my previous Samsung phones I have meticulously set up before so I doubt is anything setting related. Kinda at a loss here.
[Samsung Galaxy S21 Ultra] mrrobc97:
I got mine from eBay as well. Santa Monica Wireless to be exact. I purchased my previous 4 Samsung phones from them also (S9+, S20+, N10+, N20U) and I never had any issues and their rating is a solid 99%. I'm trying to figure out if this an actual native issue OR did we get totally new looking phones with a replaced non-Samsung cheap-ass screen.
[Samsung Galaxy S21 Ultra] Dmbruley:
Hmmm, intriguing. I've also wondered if it could be a hardware aging issue. Doubt it though.
[Samsung Galaxy S21 Ultra] mrrobc97:
Absolutely no disrespect for asking this but is this a reply you got from a Samsung rep??

This sounds like something I would get if I posted this on a Samsung forum from a Samsung rep where most users (and the reps themselves) are not Android power users and are completely unaware of what ADB, rooting, and Developers Settings is.

...but just in case I'm wrong then YES my firmware is up to date and NO I will not contact a Samsung rep because they lack imensly the knowledge I and the people here in this forum posses. Thank you though.
[Samsung Galaxy S21 Ultra] mrrobc97:
Since I don't/can't/or care to root the Samsung phones I perfer (Snapdragon with U1 firmware) the first thing I do during set-up if get all the firmware updates out of the way. I wished I could of tested for this issue while it was still on the previous Android version (what the hardware was initially supposed to run with). Did you by any chance?
[Samsung Galaxy S21 Ultra] Dmbruley:
Sadly, I did not. I updated everything and then began hacking away bloatware with ADB.
[Samsung Galaxy S21 Ultra] blackhawk:
To tell if it's light scattering caused by human eye optics simple cover the light up clock with an object to block it. Tap on AOD uses >.5% @hr with internet and phone service on. If it's doing its cloud backup crap it's going suck the battery down.

Use ScreenTest in a dark room. If all test displays look good it's probably not hardware.

Likely a coding foul up in either the firmware and/or software(s).

Both my N10+'s (Snaps) are from trusted vendors, factory sealed boxes and one is an AT&T. There are no vertical bands and the bands are dozens of pixels wide (not a row of 1 or 2, 3 pixels). It's very subtle and never visible except in a dark room. In my case I think it's being caused by One UI and/or maybe one or more apps that have overlay privileges. Given it's subtle nature it's more a curiosity and not worth chasing down the cause. I'm running Pie and Q.

If what you're experiencing is distracting or unacceptable I would return it. These displays should be perfect.

Completely free of any lamination defects. Lamination defects may prove to be progressive over time and could lead the display failure. OLEDs are extremely vulnerable the water and O2 damage/degradation if not completely sealed. This is another issue being seen of some displays and Samsung claims it's harmless. bs. They should've been rejected by QC and never made to final assembly.

Both my displays exhibit no lamination defects even after years (the oldest one) of use.

Am I all over Sammy like a cheap suit? Yes. You should be too...
[Samsung Galaxy S21 Ultra] mrrobc97:
Yup, same here.
[Samsung Galaxy S21 Ultra] KingFatty:
Can you check the size of the bezel at the bottom of the phone?

I'm thinking you somehow have an LCD screen, not OLED. Maybe the LCD screen has a different sized bezel compared to OLED. I've seen, for people who bought a "new" S21 Ultra racently, their lower bezels are noticeably larger than the original screen on the S21 Ultra, which indicates something is amiss.

Your screen is producing light when it shouldn't for OLED, but should for LCD because they have the backlight unlike OLED.

Here are two comparison pictures. Does your lower bezel look more like the first picture or the second?

[Samsung Galaxy S21 Ultra] blackhawk:
A simple way to tell is use ScreenTest and on the black screen see if any light is visible in a dark room. A LCD will have visible light emission, a AMOLED will not (unless malfunctioning).
[Samsung Galaxy S21 Ultra] mrrobc97:
Yeah I just realized that. In conclusion it has to be a LCD screen.
[Samsung Galaxy A20 Questions & Answers] tillua467:
So when i delete everything from A20 also format everything I tried to download custom rom but was greeted with this . I can't download Custom rom or anything what should I do?
[Samsung Galaxy A20 Questions & Answers] junglism93:
Hopefully you took a full nandroid backup via twrp and moved it to your pc before completely wiping the device as restoring your back up would be the quickest way out of what you have there!

I'm not up to speed on the quirks of your device regarding twrp etc so can only offer the following as ways for you to try to get a ROM Installed.

It could be that twrp needs to be rebooted to and then try installing again as you have wiped everything it may need to reset encryption and so on so to speak.

Alternatively if you still have access to your bootloader screen via button combo or reboot bootloader via ADB/fastboot then try that and then try flashing your ROM via fastboot or ADB sideload (you may need to refresh twrp if the ROM installs a recovery at install)

All the best
[Samsung Galaxy A20 Questions & Answers] tillua467:
Well I tried everything and at last I installed Orange fox then I got to found out the error and using chatgpt I got to found out the solution is to manually mount every file directory then I tried to flash rom and I got the system_root error then the recovery got frozen and finally the phone got hard bricked the mother board still collecting power and battery works to but I am not getting any response no vibration no sounds and also no screen
[Samsung Galaxy A20 Questions & Answers] junglism93:
No drama mate, can't say you haven't tried all you could 👍

I did the same when I started flashing SuperSU/Xposed and ROMs.

If your recovery supports it always take a full back up and move it to your pc before doing any mods etc, i learned the hard way myself, twice! 😉

Hopefully that hasn't put you off the modding/ROM scene and best of luck with your next device.

All the best

Nah bro same here no drama the phone was on the verge of the death any way 😆 I have root it and unroot it and download at least 15 roms? I guess but it was a great phone just installed Awaken os on Poco x2/Redmi k30(Phoneix) and it's running smoot

By

The way if you don't mind can you teach about the custom rom what gsi? Or what img flash or what is SuperSU/Xposed?
[Samsung Galaxy A20 Questions & Answers] junglism93:
I can point you in the right directions for sure, I haven't flashed a ROM for some time other than temp booting the odd GSI to see what they're like. .

For anything GSI based check the project treble forum here on XDA, it has all the relevant info you may want.

There is also an app you can use to flash GSI on a temporary basis called DSU sideloader, it's a simple to use app and works via root/shizuku.

SuperSU went end of line a long time back, probably 6 or 7 years back, Magisk has replaced it.

Xposed went the same way as SuperSU but some of the Xposedframework/mods are available via Magisk modules last I looked through Magisk forums.

Best thing you can do is hit the search button and find what interests you. I spent a good year or so trawling the forums before joining, just reading and learning.

[Samsung Galaxy A20 Questions & Answers] tillua467:
Thanks for infos tbh the phone (A20) isn't mine actually I told the real owner it won't work

But here is the interesting thing when I used use that phone when I flash magisk i got the same problem hard bricked but after like some days? It actually rebooted when I was telling others that it actually doesn't booting then I used it for a year no like 2-3 years. My guess is it would work again but I am not sure that's y I told her that it won't work
[Samsung Galaxy A20 Questions & Answers] junglism93:
No problem, there is tons of info on the forum. The search can be a bit clunky but once you get the hang of it you will find pretty much any info you need to.

Well, that A20 definitely doesn't work now 😂

Drain the battery completely, then charge it fully and see if it powers up, stranger things happen!

Good luck mate, and no more nuking other people's devices 😂

[Samsung Galaxy On5 Questions & Answers] parrots_:
I was wondering if anyone knew any guides, or if it's even possible to port ROMs with the same chipset of Exynos 3475. I did some research, and the Samsung Galaxy J2, it's 2017 variant, and the Samsung Galaxy Express Prime have the same chipset as the On5.

How would I go with porting ROMs from those devices?
[Samsung Galaxy On5 Questions & Answers] parrots_:
I was able to find some sources for the On5, but I'm not sure what to do from here.

Device Tree: https://github.com/Exynos3475/android_device_samsung_on5ltetmo

Kernel: https://github.com/Exynos3475/android_kernel_samsung_exynos3475

Will make a seperate thread trying to figure out what to do with this, because it's not really related to porting anymore.

Hello... Finally, I found another person with an Alcatel 3T 10. And I bought the stock ROM of the tablet from him. I am very happy :). But the person I bought it from bought the tablet in Europe. So Alcatel used a special ROM and model code for this. The general model code is normally 8088X, but this European ROM also has 8088X_EEA. He's not creating a problem. Anyway, I'll give you the download link.
