[Huawei P20 Pro Questions & Answers] worldsoutro:
On the p20 4G = LTE. You can confirm this by downloading LTE discovery.

VoWIFI doesn't work on any US carriers.

VoLTE works but I do not get a symbol. Its turned on for me though in call settings.

Also beware it lacks LTE band 71 and 66. 71 won't be in many areas for another year and a half so its no biggie for now.
[Huawei P20 Pro Questions & Answers] KevinAce:
Yes. My P20 Pro has been using LTE bands 2, 4 & 12 with T-Mobile. The 4G symbol is the international symbol for LTE. So yes it works.
[Huawei P20 Pro Questions & Answers] raheelc:
Thanks for the replies! After checking with the LTE Discovery app, it shows that I'm on band 4 right now.

In terms of volte, is there any way of knowing whether it's working or not, if the symbol isn't in the notification bar?

Also, in terms of the 4g icon, when I'm indoors, the icon just shows "4g" but when I step outside, it changes to a 4g icon with a plus next to it (I attached a pic). Is there any difference between the two?

[Huawei P20 Pro Questions & Answers] KevinAce:
It's very much like LTA-A (advanced) in the US. It's a faster connection. Here is a snippet about the European standard of 4G vs 4G+. And I get both symbols too but not sure if my download speeds get faster. I never checked.

"What is Double Speed 4G and 4G+?

EE offers UK cutomers data connections that are even faster than standard 4G. Its ‘Double Speed 4G’ can reach max speeds of 60Mbps – exactly double the standard 4G cap, so at least it isn’t false advertising. EE claims that over 35 million people in the UK live in a catchment area for Double Speed 4G right now."
[Huawei P20 Pro Questions & Answers] raheelc:
Thanks! Good to know that everything is working the way it should :)
[Huawei P20 Pro Questions & Answers] KevinAce:
Using the phone in the USA on T-Mobile, I experience a dropped mobile network connection every now and then. See pics for example. I can still make phone calls but I need to reboot in order to get back on the internet... As you can see even though it's not letting me use the mobile network, LTE Discovery is showing me I'm fine and on Band 4..

Just curious if you or any one else using this phone experiences this issue?View attachment Screenshot_20180711-150304.jpegView attachment Screenshot_20180711-150314.jpegView attachment Screenshot_20180711-150335.jpeg
[Huawei P20 Pro Questions & Answers] raheelc:
I'm not able to see the pictures you posted. That being said, I have not had any issue with mobile data/internet when I'm outside of the house (I'm always connected to wifi when I'm at home), but I've only been using my phone for a few days, so hopefully nothing changes.

If you can repost or provide links to your pictures that would be great. I'm wondering if there's some setting that needs to be changed somewhere, since you're stating that you're connected to Band 4, but not getting any internet (maybe the android OS is shutting off your mobile connection after a certain time of inactivity?)
[Huawei P20 Pro Questions & Answers] KevinAce:
I reposted photos. Hopefully you can see them. I turned off the setting on the phone to always default to WiFi if available. So that should keep my device going with the network connection. It's very random and I see nothing about mobile network time out settings. I do have LTE Discovery installed because I wanted to compare network connectivity to my Mate 10 Pro with my new P20 Pro. That allows you to restart your cell radio. I'm going to uninstall that app just in case maybe that app is causing the issue...
[Huawei P20 Pro Questions & Answers] frewys:
Had this phone on T-mobile since it was released and had zero issues with it

I fact audio quality and stability is better than my previous tmob galaxy s8
[Huawei P20 Pro Questions & Answers] raheelc:
Hmm yeah not sure what's going on. I know it's obvious but have you tried restarting the phone, or tried a hard reset and wiping everything and starting fresh?

---------- Post added at 01:13 AM ---------- Previous post was at 01:12 AM ----------

I concur. So far no issues at all. And the call quality etc is noticeably better than my OnePlus 5t. Calls connect noticeably faster too.
[Huawei P20 Pro Questions & Answers] KevinAce:
Restarting the phone fixes it every time. But it's annoying as it happens once or twice a day and shouldn't happen with brand new phone.

How do you do a hard reset?

I've been holding off on full wipe and start fresh as last resort just because it's so time consuming to set phone up from scratch. I don't want to use a back up or phone clone of I factory reset as I think same problem might emerge.

One thing I noticed and I'm hoping this was the problem. T-Mobile Visual Voicemail sometimes has issues connecting. The mobile network went out while visual voicemail was trying to connect so I deleted the app altogether and I'm going to see if the problem is gone... I hope so as I really have the phone set up the way I like it with Nova Launcher and all my apps organized and configured perfectly.
[Huawei P20 Pro Questions & Answers] raheelc:
A hard reset is just a full wipe and fresh start, as you mentioned.

I know it's time consuming to set up a new phone after a wipe, I just got mine set up the way i like after a few days of setting up everything. Hopefully it won't come to that.
[Huawei P20 Pro Questions & Answers] Chaz43:
I actually got the same issue with my P20, and it seems to have the same issue if it connects to wifi for a while and then I go out of wifi range. I also got this disconnect issue until I restart my phone. So you are not the only one with this problem. No clue about the cause, but do agree with this is an issue.
[Huawei P20 Pro Questions & Answers] KevinAce:
For me, I leave WiFi off all day while I'm at work. So I'm only on LTE and the mobile network. When it disconnects, I can still make calls, just no internet service...
[Huawei P20 Pro Questions & Answers] watchnj:
Hi , did you find the solution for the internet disconnect problem ? I am having the same exact issue as you ,

I did a hard reset but problem still here
[Huawei P20 Pro Questions & Answers] z06mike:
Are you using a CLT-L09 or 29???
[Huawei P20 Pro Questions & Answers] frewys:
29
[Huawei P20 Pro Questions & Answers] webadass:
I am from the US and currently in Singapore, where I am considering picking up a P20 pro.

CLT-L29C: Dual SIM Card

LTE TDD / LTE FDD / WCDMA / EDGE / GPRS

Will this work with AT&T or T-mobile in the US? Will it have wifi calling? (I live in an area with subpar reception and use wifi calling extensively)

Thanks.
[Huawei P20 Pro Questions & Answers] RockStar2005:
So if I use DIGITS while Wi-Fi is active, it will make the call in Wi-Fi??

I guess when not needing Wi-Fi calling, I can just disable the app.
[Huawei Mate 10  Questions & Answers] bryancotton84:
I just started receiving a pair of random error notifications. Nothing specifically triggers the messages and they go away after several minutes of popping up. I've searched within the phone settings and here but can't find any information. Anyone know what these are?!
[Moto E4 Questions & Answers] rockyroad982:
So I have a qualcomm moto e4 and I rooted it with magisk, The problem is that even though I removed the play store from /system/priv-app and from /data/app, the playstore keeps on coming back magically!

Is their another apk that i should remove to stop this?
[Moto E4 Questions & Answers] madbat99:
Dude, no. Your phone won't even function on stock without it. There are a few Google apps that if you remove, phone will just lock up. If you have magisk, use the debloater module and see. If you want to run without gapps, flash a rom and don't flash gapps with it. Stock is dependent on a few of them.
[Moto E4 Questions & Answers] rockyroad982:
It actually functions fine when i fully remove the playstore but then play services stop working. Is their an alternative for play services that does not require app spoofing like micro g?
[Moto E4 Questions & Answers] DB126:
No - custom ROM or micro g. Look around; if such a solution was viable there would be plenty of banter.
[Google Pixel 2 XL Questions & Answers] dmt1386:
Hi everyone. I'm a newbie in here. There a problem with my Pixel 2xl phone.

First, I already unlock bootloader, but my wrong I relocked again ( I know that stupid). Second, I can't unlock bootloader again and can't get into recovery mode and it said that can't find valid operating system. I tried many many ways ( try another laptop, cables, firmware...). Finally, I can get into download mode by the method to get recovery mode ( It's like last chance for me). Please help me how to install firmware os in download mode. Thank you so much.

P.S: I got that phone from Roger, but they don't allow to warranty. [IMG="https://photos.app.goo.gl/ZglzB1oYvYexHiIH2"]https://photos.app.goo.gl/ZglzB1oYvYexHiIH2[/IMG]

[Google Pixel 2 XL Questions & Answers] Badger50:
If you locked your bootloader, which you probably shouldn't have, about the only thing you can do is side load an OTA through stock recovery. Google has the instructions here. https://developers.google.com/android/ota

Does fastboot recognize your device when you type in..fastboot devices...?
[Google Pixel 2 XL Questions & Answers] dmt1386:
[MENTION=3730810]Badger50[/MENTION]

Sorry for late reply and thank you about ur answering. The fastboot recognizes my device when I plugin but I can’t flash stock because the device state is locked and also can’t unlock bootloader. Again, thank you so much and have a nice day
[Google Pixel 2 XL Questions & Answers] billycar11:
if you cant get into recovery your pretty much done im unsure if this works on locked phones but you can try to download the factory image from here https://developers.google.com/android/images extract the recovery and then fastboot boot recovery.img and then download the full ota here https://developers.google.com/android/ota as badger said to flash in recovery
[Google Pixel 2 XL Questions & Answers] uicnren:
what is preventing you from unlocking the bootloader again?

have you tried flashing the full OTA images?
[Google Pixel 2 XL Questions & Answers] billycar11:
when it says os invalid it cant read if the enable unlocking box is checked or not so it does not allow unlocking
[Google Pixel 2 XL Questions & Answers] Scott:
Was the OEM switch on before you re-locked?
[Google Pixel 2 XL Questions & Answers] billycar11:
im unsure if [MENTION=9086463]dmt1386[/MENTION] had it on or off im not the op
[Google Pixel 2 XL Questions & Answers] dmt1386:
[MENTION=4525761]billycar11[/MENTION]

thank for helping. The device state is locked and also can't unlock bootloader. I can't fastboot anything. BTW in the factory image, I can't find recovery.zip.... Thank u and have a nice weekend.
[Google Pixel 2 XL Questions & Answers] dmt1386:
[MENTION=426561]Scott[/MENTION]

I'm not sure but I think that OEM locked at the same time I re-locked bootloader.
[Google Pixel 2 XL Questions & Answers] simplepinoi177:
Why can't he/you (OP) do the unlock command again at bootloader?

...It looks like he (OP) simply ran the lock command, I doubt he went in, unchecked OEM unlock, then got into bootloader and ran the lock command.

But, whenever I find that, at loading, it (any software) can't find OS, it usually means boot pointing issues. And, as there is a confusing thing about our phone and Slot A or B, I wonder if switching slots might be key; i.e. whatever he did, he made Slot A so it can't be accessed and/or hidden so it shows as there isn't OS, but what if he tried switching his active slot to Slot B?

Sorry dmt1368, I'm rather lazy to find the specific fastboot command. Probably one of these other awesome fellows will do. But if you respond to me and no one has, I'll find it for ya...

Good luck to ya and hope this helps...

[Google Pixel 2 XL Questions & Answers] simplepinoi177:
Yes, I understand "there is no OS", I am talking about

before

it broke and you typed something like "fastboot flashing lock"... did you do something like un-tick "OEM unlocking"?

When you go into Bootloader mode, can you do the fastboot command:

fastboot flashing get_unlock_ability

When in bootloader, can you choose/select Recovery?
[Google Pixel 2 XL Questions & Answers] dmt1386:
that what I said above, I can't get into recovery. It just shows up Download mode ( firmware update). If I can get into recovery, I can use adb sideload ...
[Google Pixel 2 XL Questions & Answers] simplepinoi177:
Go to this "Download mode"...

While in it, I want you to press and hold the power button, and then quickly press Volume-Up!

I think I see what you misunderstood...in Oreo/8, it looks like what previous Download Mode looks like, but it actually isn't! That is actually recovery, but it seems Google didn't want to make it obvious about it.
[Google Pixel 2 XL Questions & Answers] dmt1386:
What happen when I press and hold the power button, and then quickly press volume -up , that is DOWNLOAD MODE ( because this is same way I get into recovery before). but the computer doesn't recognize my pixel and my question in this topic is how to install stock in Download mode (Pixel 2XL made by LG, and many LG devices flash by that way)
[Google Pixel 2 XL Questions & Answers] simplepinoi177:
I believe you are getting these confused...and to get into what you believe is DOWNLOAD/recovery before would've been volume-

down

, not up. But i also noted that recovery on Oreo looks like Download mode on anything Nougat and lower...

So go into bootloader, use volume buttons to cycle until it shows "Recovery Mode". Then press Power button. Let it load. Now, regardless of what you believe is Download mode or not,

this

is where you hold the power button, then quickly press volume-

up

.

I have this phone and I wonder how does EMUI manages the RAM in the smartphone?

Since I'm usually am running out of it, as the applications in the background gets closed when I'm using a different application like Youtube, for example.

Any idea how does EMUI manage the memory of the phone when I'm using the application?

Also, how does AI actually manages the memory of the phone? Is it marking bull****?

And is there a way to fix it so EMUI is able to use RAM more efficiently on my smartphone.

Thanks for the help, in advance. :)
[Huawei P10 Questions & Answers] Silently:
You have a finite amount or memory. If you use more in the foreground then background apps will have to close... that's just the physics of it.

You can try 'locking' the apps you don't want to close in the recents tab, but that can only help so much.

I am having the same issue. Plus with the auto-brightness deactivated, the screen changes the brightness as her wish, and sometimes the screens turns on without getting a notification. I asked for help in this forum, you can search the thread, but the only solution that they gave me, was that i make a wipe cache and a factory reset and the problem will be gone. I did it, i even downgraded again to nougat, and then update again. Nothing didn't work, so early this week i leave the phone on a tech support, and im waiting. Try the solution for yourself and if it doesn't work, do the same, go to the tech support. (sorry for my english)

The same happened to me as well after the july update. Pulldown bar goes up in 2 slides, but down, it opens completely from just one slide. I did have a custom theme installed which modified the collors of the icons in the pulldown menu. I guess this was affected by the update. Problem is I can no longer find the theme to reinstall and uninstall. I am hoping for a solution besides a factory reset
[Huawei P10 Questions & Answers] DallasCZ:
backup and factory reset and restore. .... manner of 1 hour. Its highly recomended to do FR (factory reset) every major update nad update form nougat to oreo is one of these.

I have no screen issues or auto brightness or self turning on of display.

For the pulldown menu. When i have no notifications and swipe down i see all 2 rows of switches and brightness bar. When i have some notifications after swipe down i see only first row of switches and the notificitaion and i have to swipe again to see full notification list. Its how its mean to work on Oreo. Get used to it or go back to nougat :D
