[Samsung Galaxy S8 Questions and Answers] SevenD2:
If you download the app Accubattery you can see the amp going to your phone

One thing I noticed is when the battery gets too hot it'll stop fast charging ~33 C. (Drops from ~2500 mAh to ~1200 mAh)

One trick I found is to charge while having the phone under running water to keep the battery cool (of course don't get water near the port!)
[Samsung Galaxy S8 Questions and Answers] Ab SiD:
The same happened with me too. Just take a mini brush and clean the charging port and kuddos it works fine. Now mine is perfectly working.
[Samsung Galaxy S8 Questions and Answers] xFac3R:
i think it software problem..
[Samsung Galaxy S8 Questions and Answers] Ab SiD:
No, but that happened for me too. But now its totally fine as i brushed off dust from the port.

[Huawei P20 Pro Questions & Answers] cdl2:
Not a question, but an FYI.

I bought the dual sim version (CLT-L29) of the Huawei P20 Pro in the UK, from clove.co.uk

FYI (hoping it’s useful to other people): I have tested it with the 3 major networks in the UK, and wi-calling works with all 3, even if the phone is an unlocked dual-sim version, not bought from the networks.

At least where I use it, Vodafone has the best indoors signal. Outdoors, Vodafone and EE are about the same. Three is by far the worst, both indoors and outdoors.

EE: I get no icon about wi-fi calling, neither in stand-by nor during a call, but I am sure wi-fi calling works because I managed to call while in an underground station, where there was wi-fi but not mobile signal.

Three: no icon that wi-fi calling is available, but the small text “wifi” appears when making a wi-fi call.

Vodafone: icons and notifications about wi-fi calling being available come and go multiple times. Sometimes I can get 4 notifications, with the phone vibrating, in 10 minutes. It’s very annoying. I had to go to setting -> apps -> more -> show system processes -> phone -> notifications -> wi-fi calling and disable all the options (display in status bar, etc.) to make sure I don’t get these continuous notifications. However, I tested wifi calling in an underground station, with a wifi connection but no mobile signal, and it worked.

In all 3 cases, I enabled wifi calling opening the dialler -> 3 vertical dots at the bottom right -> Sim 1 (or 2) -> wifi calling

Wifi calling was already enabled by default with EE and Three; with Vodafone, it was tricky: I tried enabling it from the Vodafone website and from the Vodafone android app, but it didn't work. What worked for me was the online chat with Vodafone's support, who enabled it on their end. Odd.

Another thing I noticed is that, on my old Samsung Galaxy s7 edge dual sim, only the sim which connects to the internet could have wifi calling. Here no, both sims can have wifi calling enabled at the same time.

Is there any way that I can disable system updates at this phone? I ll stay at this Oreo

[Huawei P20 Guides, News, & Discussion] Luis2k33-XDA:
I can boot on TWRP but it doesnt opened stuck in boot picture... all of it was because i format /data throught TWRP with the phone conected, so when i saw the warning "the /data partition is mounted" i shut down the phone, to try to reboot TWRP but nothing...
[Huawei P20 Guides, News, & Discussion] smohanv:
It seems your phone partitions except fastboot (bootloader) are corrupt.

Flash CUST.img, RECOVERY_RAMDIS.img, KERNEL.img and System.img extracted from UPDATE.APP of EMUI 9.0.

Boot back to fastboot and flash TWRP this time. Boot to recovery with the command fastboot reboot issued in fastboot mode.

It should now boot in to TWRP recovery. Now you can do whatever you would like to.

As long as you don't touch bootloader partition (fastboot partition), you can always get connected to your PC.

Power off completely. Quickly press volume down and connect USB cable. You have to do it in a quick action.

10. Follow the steps below,

## Download the EMUI version that you need from the link https://pro-teammt.ru/firmware-datab...rmware_page=0/

## Rename the file update_full_CLT-L29_hw_eu.zip in to update_all_hw.zip

## Create a folder ZIPS-HERE in the same folder where you have ADB tools (as explained in the section above) and put both update.zip and update_all_hw.zip in this ZIP-HERE folder.

## Download update_data_public.zip from this link and copy to the same ZIPS-HERE folder

## Download this nocheck.img file and copy it in to the same folder ZIPS-HERE. link here: https://www.androidfilehost.com/?fid...63190603873636

## Issue following commands (you can copy and paste in the command window)

adb shell twrp decrypt

adb push ZIPS-HERE/update.zip /data/update/HWOTA/update.zip

adb push ZIPS-HERE/update_all_hw.zip /data/update/HWOTA/update_all_hw.zip

adb push ZIPS-HERE/update_data_public.zip /data/update/HWOTA/update_data_public.zip

adb push ZIPS-HERE/nocheck.img /data/update/nocheck.img

adb shell "echo --update_package=/data/update/HWOTA/update.zip > /cache/recovery/command"

adb shell "echo --update_package=/data/update/HWOTA/update_all_hw.zip >> /cache/recovery/command"

adb shell "echo --update_package=/data/update/HWOTA/update_data_public.zip >> /cache/recovery/command"

adb shell dd if=/data/update/nocheck.img of=/dev/block/bootdevice/by-name/recovery_ramdisk

adb reboot recovery

bad news. I did the same. only option you got is warranty or servicing device yourself. if you can, send it to warranty. if you can't then here is the solution. but bad news upfront, you will open your devices back, unplug battery and shortcut somethings, also will need a 19euro app. I got it working from that thread.
