I restarted and reset the settings to factory defaults, but it didn’t fix the issue. However, in some apps like Instagram and Telegram, the camera seems to work correctly in the background.

Why isn't my phone charging anymore?

The charging plug doesn't go all the way in and consequently it doesn't charge anymore, there doesn't seem to be anything in the charging socket

Huawei P30: How do I leave "Ultra Power Saver Mode"?

Sat, 18 Feb 2023 02:09:00 -0700

How do I turn off the Ultra Power Saver Mode? I turned it on earlier today due to low battery, after recharging it, I went to turn it off and the UPSM is just locked on “on”, and I can’t turn it off whatever I click, yet at the same time I can put it into Performance mode, to have both “Performance Mode” and “Ultra Power Saving Mode” on, at the same time.

Huawei P30: P30 lite - not charging screen dimmed

Fri, 24 Dec 2021 08:41:19 -0700

Hello,

I got a P30 Lite that suffered water damage and would not turn on again.

I replaced the Main Board, charging board, cables,…etc. and now it starts but the screen is very dimmed. I could only see it with a flashlight.

I tried hard reset, tested with a new screen, another battery,…etc., same issue.

I also noted that when i connect the charger, the phone doesnt charge and the battery starts dropping down.

could this be a faulty main board? or other parts? I am lost.

Thanks

Huawei P30: Huawei P30 got into water, screen doesn't function but others are fine

Wed, 09 Sep 2020 18:33:55 -0700

My phone got into water while I was doing white water kayaking. Water was not absorbed immediately, but I put the phone into a zip bag with dryrites. Now it is completely dried. I can actually turn it on and messages are coming in, but the screen keeps shut off. So I wonder if simply changing the screen could save my phone. What are your thoungts? Thanks for your help!

Huawei P30: Purple and blue bleeding from right of screen.

Sat, 11 Jul 2020 05:47:25 -0700

OK, so, I dropped my phone. When I picked it up, the bottom half of the screen was blank, but would still respond to touch ( it still recognised my thumbprint, etc). I restarted it, and everything was fine except for a horizontal line across the screen and a few light blue pixels at the far right. Now, about 2 hours later, a small purple and blue patch has grown on the screen, and is still very slowly growing.

Can anyone tell me what's wrong with it? I'm going to get it checked out on Friday.

Can it be fixed?

Huawei P30: Some parts of phone screen has been unresponsive for months

Thu, 16 Apr 2020 18:32:02 -0700

Horizontal rectangles of parts of screen (such as the most top part, so i cant pull down the notification bar) is unresponsive but there’s still display. I dropped it (again, for the last time), the screen went crazy like green and black streaks. Now, its just a black screen. I switched it off with the power button (there was a vibration indicating that it switched off). What can I do?

Huawei P30: Dropped my screen with screen protector - screen stopped working

Thu, 09 Apr 2020 08:12:50 -0700

I dropped my Huwawei P30 on the ground in my garden (which is unfortunately stone floor). It hit the top right hand corner and now my screen no longer works. The phone is still vibrating when I restart so I THINK it’s still functional but there are just occasional lines popping up. Does anyone know how I can fix this by myself since lockdown means that no phone stores are available?
