[Xiaomi Mi 10 Ultra Questions & Answers] AerationCheese:
No notification problems other than when I have battery saver on, seems to disable all kinds of sync so you only get emails by opening Gmail and forcing a refresh for example. I've never had battery saver be that aggressive on another phone, but it's not a huge issue for me. Notifications work fine otherwise.

No issues with google messages either. When I get home and can type better/longer messages than on my phone, maybe we should compare settings and see if we can find what's causing that.
[Xiaomi Mi 10 Ultra Questions & Answers] AerationCheese:
Just a wild guess but you don't have this enabled do you? Maybe this causes an issue when it's incorrectly detecting your sleep schedule?
[Xiaomi Mi 10 Ultra Questions & Answers] golddragon97:
I see. That means I would have to turn off power saving mode? I was trying to save battery on everything else while getting my notifications in a timely manner. I've had a Mate 10 Pro before this and I thought that was aggressive.

It's alright. I've messed with it all morning and all I did was reinstall and allow all permissions again. It works now. Turns out the other party didn't turn on data on their iPhone.

Perhaps. but I'll look for this and keep an eye on it. Thanks, I didn't know this existed.
[Xiaomi Mi 10 Ultra Questions & Answers] vtec718:
Just got the phone and using on T-Mobile. Noticed I'm not getting any notifications even though I've set Gmail to sync, permissions on, no restrictions whatsoever as I can see. What's going on.
[Xiaomi Mi 10 Ultra Questions & Answers] AerationCheese:
Do you have battery saver on? What about that sleep mode thing in the screen shot above?
[Xiaomi Mi 10 Ultra Questions & Answers] vtec718:
Both battery saver and sleep mode are toggled off.
[Xiaomi Mi 10 Ultra Questions & Answers] AerationCheese:
Oh I bet I know. Try going into each app's settings page and turn notifications on if they're off, and if they're on, change the notification priority to high.

It's annoying but once you do it on apps you shouldn't have to do it again. I have no idea why it's setting some apps to not have notifications by default or setting them as low priority so they can't pop up or make any sounds.
[Xiaomi Mi 10 Ultra Questions & Answers] vtec718:
I've toggled them off and then on again and it seems to be working now. I will report back if I'm still having problems. Thanks
[Xiaomi Mi 10 Ultra Questions & Answers] gb155:
How are the notifications? I had a mi mix 3 and had nothing but hell trying to make them work, I now own a oppo find x2 Pro and again I'm having issues (Chinese version) so am looking at moving this on if there is no Rom flashing available soon and was waiting for a oneplus 8t but this new MI 10 ultra excites me, I just can't have yet another phone with notification issues.

Thanks

Apologies I missed the above, my Chinese PDEM30 oppo find x2 Pro doesn't allow me to change launcher, does the mi 10 ultra?
[Xiaomi Mi 10 Ultra Questions & Answers] vtec718:
Seems like I still have the same notifications issues as I did with my S20 Ultra. Sometimes I get the notifications on my lock screen and sometimes I have to turn the phone on for them to popup and appear. I learned to live with it on my Samsung so I guess I'm okay with it.
[Xiaomi Mi 10 Ultra Questions & Answers] AerationCheese:
While I'm here I highly recommend not ever enabling super battery saver. All it does is keep you from opening most apps and when you turn it off you have to reconfigure a lot of things on your phone, especially if you use any Google services. Not worth the trouble. Regular battery saver should help enough.
[Xiaomi Mi 10 Ultra Questions & Answers] AerationCheese:
Yes, you just have to download miui hidden settings, go to apps, show system apps, then open the launcher app settings and change it there.

Personally can't wait for a custom ROM on this phone
[Xiaomi Mi 10 Ultra Questions & Answers] vtec718:
After getting up and started using the phone. I noticed the phone behave likes it was on 60hz even though it's set to 120. Had to do a reboot to get it to act normal again. Anybody else notice this too?
[Xiaomi Mi 10 Ultra Questions & Answers] BlueMeany68:
I'm same as you - have oppo find x2 pro (global) and looking at moving it on and getting this one.
[Xiaomi Mi 10 Ultra Questions & Answers] gb155:
Didnt even realise until today i couldnt change the default SMS either, so no launcher or SMS other than default, its like a bloody iphone this LOL

I assume these can still be changed in MIUI on the note 10 Ultra?

Can it be unlocked and a global flashed? (Not had a xaiomi for a few years)
[Xiaomi Mi 10 Ultra Questions & Answers] AerationCheese:
I assume you mean Mi 10 Ultra?

Haven't run into any default apps that can't be changed yet. Some require a little work like the launcher but that's it. It can be unlocked after a waiting period of something like 15 days, no global ROM yet but there is a xiaomi.eu custom ROM and you can be sure more custom ROMs are coming.

does VoLTE or VoWIFI (Wifi Calling) work?
[Xiaomi Mi 10 Ultra Questions & Answers] AerationCheese:
Volte yes, wifi calling no, I've never had wifi calling work on any device on AT&T personally.
[Xiaomi Mi 10 Ultra Questions & Answers] AerationCheese:
Wifi calling does not work on non-att android devices. It's no different for this phone.
[Xiaomi Mi 10 Ultra Questions & Answers] gigaflop:
Unrelated to Mi 10 Ultra but I took a Canadian Samsung Note 20 Ultra lastnight and flashed USA ATT firmware. Wifi calling/VoLTE work and the device is not from ATT.

I am thinking since both devices are Qualcomm based, if the Mi 10 Ultra is rooted and we can get a MBN config file for the Qualcomm PDC tool maybe we can load up the ATT VoLTE/VoWiFi settings on the Mi 10 Ultra and get wifi calling working?

e.g. https://xdaforums.com/poco-f1/how-to/guide-activate-vowifi-wlan-call-t3871263

Edit....

I did some digging and found that there are some PDC Profiles for North America already on the Mi 10 Ultra itself

[Xiaomi Mi 10 Ultra Questions & Answers] terryYew:
Hi. I have been wavering between this and the P40 Plus. I asked this question in another thread but maybe it was buried and i didn't get a reply.

Do you have a major syncing problem as explained in this review? Also, Where did you buy yours from? I'm looking at Liaow.com
[Xiaomi Mi 10 Ultra Questions & Answers] AerationCheese:
No sync problem at all. I'm wondering why other people are having that issue. Maybe they're restoring backups with the mi backup/restore app? Restoration apps have been known to break things like that. I used Liaow.com, fast shipping and his communication was friendly and helpful.

Wow, Ive been looking at this phone recently, it's such a great phone feature wise and price! I'm also in milwaukee Wisconsin!

"I get about 55mbps which doesn't sound fast but it's massively faster than I get with LTE personally."

You made it seem like signal was /service was pretty bad. Is it usable day to day for someone who uses there phone in a commercial environment,but it must have reliable service. Don't care about 5g really but a usable good lte is fine with me.
[Xiaomi Mi 10 Ultra Questions & Answers] mbessio:
Hi AC,

Thank you for your offer to answer our questions.

Mine is ordered and on its way. I am as well an ATT customer and currently using a Pixel 4XL.

I have tried chinese phones in the past and ended up returning all of them for one reason or another.

My main concern will be call quality and banking/credit card apps. Should I be concerned or they work fine?

Thank you again
[Xiaomi Mi 10 Ultra Questions & Answers] AerationCheese:
No that was a compliment. Some people hear 5g and think it's **** if it's not like 900mbps, but for low band 5g 55mbps is about in the middle of the expected speed range. I've only had 4g phones before and the best I got on lte was usually only like 20mbps, so even though 55 doesn't sound fast, it's good for low band and way better than LTE.
[Xiaomi Mi 10 Ultra Questions & Answers] AerationCheese:
All of my calls have been perfectly fine and no issues with banking apps. Just be ready to uninstall crap and spend a little while setting up custom launcher/keyboard/etc. If you go into the apps list in settings, then go to manage apps, it has a convenient screen to select any apps you want to uninstall all at once.

Then to remove system apps you can turn on USB debugging and use the xiaomi adb debloat tool (easy to find via Google)
[Xiaomi Mi 10 Ultra Questions & Answers] mbessio:
Thank you for your quick response and insight.

Any suggestions for which system apps to uninstall?
[Xiaomi Mi 10 Ultra Questions & Answers] AerationCheese:
As far as the adb toolkit goes you'll have to research on your own, I don't recall what I disabled (I would recommend disabling not uninstalling when using the adb tool, easier to fix if you break something). If you don't recognize a package name Google it and see if you can find anyone talking about their uninstall experience.

For the apps that are uninstallable within the system, just uninstall anything you don't think you'll use. I uninstalled almost everything that was able to be uninstalled really because for stuff like the gallery and video viewer there are much better alternatives.

Does VOLTE work with AT&T?
[Xiaomi Mi 10 Ultra Questions & Answers] AerationCheese:
Yes.
[Xiaomi Mi 10 Ultra Questions & Answers] izzysomms:
@AerationCheese Re-VoLTE working on AT&T—that means you get the VoLTE symbol in the status bar when you're on call/the phone doesn't switch to H+ or something for data when you're on a phone call? Just to verify, if you install this network app and make a phone call, what does it say under "Voice Network Type"?

Not trying to doubt you, just wanting to be sure because AT&T's network changes in February 2022 are going to make non-VoLTE phones ineligible for the network.

Do you still use the Mi 10 ultra on AT&T? I got mine early this week but when input my Cricket sim in, the blocked my sim. Shady that the US companies are trying to force people on Samsung and Apple phones.
[Xiaomi Mi 10 Ultra Questions & Answers] AerationCheese:
Still using it fine on AT&T.
[Xiaomi Mi 10 Ultra Questions & Answers] wud_e:
I think I'm going to try taking it to the ATT or Cricket store. I've been using a Mint trial sim and haven't had any issues. I'd prefer Cricket though since I have my real line and other family lines there still. Maybe it's all about them wanting the upgrade fee to 5G service. (maybe they block using their Sims in unlocked 5G phones) That is the issue which I didn't realize was a thing until I asked my wife to do a speed test on the ATT Samsung she just activated there. The speed test was to compare Mint vs Cricket and when I saw her getting only 4G I asked her about it and she said they charge extra for 5G. Will report back what they say in store.

[LG V40 Themes, Apps, and Mods] AsItLies:
This module was written by Vlad48 for the V50, I made a slight change for it to work with V40. My V40 is running NAO Pie, and this module works on it, but has not been tested on any other V40 variants.

While there's another option to accomplish this; 1 being an app from playstore, which doesn't appeal to me as I'd prefer to install as few apps as possible. Another option is using adb and su and changing carrier id to VZW, that didn't work for me (it booted and said 'not an VZW sim' and phone app kept stopping).

I've changed this module to include both of the dir paths for the 40 and (original) 50, so I **think** it should work on both 40 and 50 and both Pie and Q. Please indicate if this does or doesn't work for you if you have any of those variants, thnks.

(same problems with crDroid; stock ROM (Pie) works fine)

Redmi Note 8

Clean install: Format & wipe

After adopting SD and migrating data I'm having some problems. Tested with 2x 128GB cards and 1x 64GB cards, same problems every time. Also tried fresh re-installs with format & wipe, same problems.

When copying files to "/sdcard" (aka "/mnt/runtime/full/emulated", aka "/storage/emulated/0/") I keep getting corrupted directories; directories that I can't write to, I can't delete, I can't move/rename, I can't change permissions, I can't change owner/group. Every time this happens, "df" shows more space being used, but files can't be found.

Problem happens when copying files to adopted storage via "adb push", tar, zip, cpio, and MTP.

I've also tried extracting from a zip file using a GUI app, and also deleting borked directories with a GUI app: No joy.

This is a major problem. This is making it impossible to load up the SD card with the files I need.

Just trying to "adb push" a TitaniumBackup directory to the new phone, and it gets to about 70-80% and then dies with this error:

adb: error: failed to copy 'TitaniumBackup/com.android.theme.font.xxxx-xxxxxx.apk.gz' to '/sdcard/test/com.android.theme.font.xxxx-xxxxxx.apk.gz': remote couldn't create file: Invalid argument

It keeps dying at slightly different points, but every time it dies it corrupts the directory that I'm copying into; I can't delete it, I can't move/rename it, I can't add anything to it, etc. "df" shows that space is being consumed, but there's no files. The sdcard just keeps getting corrupted, every time.
