[Update: Fixed] Huawei P30 fingerprint sensor icon blinking issue officially confirmed

This story is being continuously updated….new updates are being added at the bottom…..

Chinese multinational telecomm equipment and consumer electronics producer Huawei expanded their lineup of smartphones by releasing their latest flagship devices P30 and P30 Pro back in March this year. And this month, the P30 series’ mid-range device P30 lite also joined the club.

On OS terms, while both Huawei P30 and P30 Pro come baked with Android 9.0 (Pie) and EMUI 9.1, P30 lite comes with Android 9.0 and EMUI 9.0. Coming to the SoC, P30 and P30 Pro are shipped with HiSilicon Kirin 980 (7 nm) chipset compared to P30 lite’s Hisilicon Kirin 710 (12 nm).

Although the devices are barely a month old, but as is the ritual, bugs and issues spare none, and same is the case with Huawei P30.


Huawei P30 Pro

As some of you may already know, Huawei P30 comes with an in-display fingerprint sensor – a currently popular feature that other OEMs’ flagships like Honor View 20, Samsung S10/S10+ and OnePlus 6T also embrace.

Here’s a glimpse of the Huawei P30 series.

But going by reports across different social media platforms, Huawei P30’s fingerprint sensor icon is behaving out of order and is acting a bit buggy.

Basically, Huawei P30 users have been complaing that their device’s fingerprint icon keeps blinking randomly even when the phone’s kept idle. That means, there is no particular pattern as the fingerprint sensor icon blinks intermittently.

The weird behavior wherein fingerprint sensor icon keeps popping up on its own is making users curious about sensitivity of the device’s screen and battery consumption.

Complaints can be seen posted across Huawei’s official UK forum, HuaFan forums and others. And here’s how some of the affected users word the problem:

Got my Huawei P30 3 days ago and noticed one suspicious behavior on the idle phone, even when I’m quite far, and there are no moving objects near the phone – it would display the fingerprint icon on the black, idle screen.

I bought a Huawei P30 3 days ago and noticed one suspicious behavior, even though I was quite far away from the phone (np. 1.5m) – on a black screen it would itself display a fingerprint reader icon in the display (randomly every 30-60 seconds).

We’re definitely not the only ones, I see the issue popping up here and there in some forums. P30 pro is definitely no affected, only some P30 which would indicate some HW differences. I tested every sensor on the phone and they all work as intended.

Sadly, we don’t have a P30 phone at the moment to test the problem behavior at our end. In addition, we didn’t come across a video or any other kind of proof that clearly shows the problem. But going by the number of reports, it’s safe to say that the problem is affecting a lot of users.


Users complaining on Huawei UK forums

Is the issue a known one?

What’s appeasing is the problem has been officially acknowledged by a Huawei employee at the company’s official UK forums. They not only confirmed the issue but also informed users that the same shall be fixed with the May update next month.

Here is the Huaweian’s exact statement:

We are working on this issue and expect to release a new version in May. Please wait patiently for the system version update.


Huawei employee’s response to one of the complainants

We hope the promised fix gets delivered soon. But unless that happens (which will be in next month), there’ no workaround as such that may temporarily resolve the issue. Rest assured, we are keeping an active tab on all developments and will update the story as and when required.

Update 1 (April 16)

Soon after we published this story, one of the Huawei P30 users who themselves have been facing the fingerprint icon blinking glitch on their unit contacted us and shared with us a couple of video clip showcasing the problem behavior.

Take a look at the clips that they shared to catch hold of the problem discussed in this article:

Here’s another video (a longer one) that displays more frequent blinking of the fingerprint sensor icon (15 second onward).

Thanks for sharing with us the video clip @Punyawee Sukrongpang .

Update 2 (April 18)

Incoming is a good news. The same Huaweian recently informed the concerned users that the fingerprint sensor icon blinking glitch has been resolved internally. The fix for the same will be made available in the next update. Here’s there exact statement:

This phenomenon will not affect the normal use of fingerprint function, please rest assured. We have solved this problem and expect a new version to be released later. Please wait patiently for system updates.

Update 3 (May 08)

Going by latest reports, EMUI update has resolved the finger sensor icon blinking issue. Here’s what a user said while confirming the fix:

I had the same problem, today I recieved the .153 update and it fixed the blinking issue. The fingerprint icon changed as well from the white one to the metallic version.

P.S. Huawei Mate 20 Pro users have been reporting that Work profile on their devices gets locked after every update and throws invalid pin error. Head here to read the complete story.
