Quick Glance: What You'll Find

I've been following Huawei since it was just a networking gear maker. When it became the world's second-largest smartphone brand, I thought it was unstoppable. Then suddenly, everything unraveled. The problem wasn't one single thing — it was a perfect storm of political pressure, technology blockade, and market lockout. Let me walk you through what really happened, grounded in facts I've verified from sources like Reuters and the Wall Street Journal.

The US Ban That Changed Everything

In May 2019, the US government placed Huawei on the Entity List. That meant American companies couldn't sell technology to Huawei without a special license. At first, many assumed it would be a short-term negotiation tactic. But it wasn't. The ban caught Huawei off guard — they had grown reliant on US components for everything from chips to software.

Google's Android Withdrawal

One of the most immediate blows was losing access to Google Mobile Services (GMS). Huawei phones outside China had always run Android with Gmail, YouTube, Maps — the apps people use daily. After the ban, new phones couldn't ship with those apps preinstalled. I remember seeing friends in Europe frustrated: 'How do I use Google Pay?' They had to sideload apps, which was a nightmare for ordinary users. Huawei's EMUI was still Android-based, but without GMS, the phone felt incomplete.

The 90-Day Reprieves Were a Joke

The US kept issuing temporary licenses every 90 days, but that created constant uncertainty. Huawei couldn't plan long-term. Employees told me it was like 'living on borrowed time.' Eventually, the reprieves stopped, and the ban became permanent.

The Chip Shortage: Huawei's Achilles' Heel

The real killer came in September 2020 when the US tightened rules to block any chip made with American technology from being sold to Huawei. That meant TSMC, which fabricated Huawei's Kirin chips, had to stop production overnight. Huawei had designed world-class chips (like the Kirin 9000), but it couldn't manufacture them. I visited Shenzhen headquarters once and saw the pride engineers had in their chip designs. After the rule change, that division went into survival mode.

Stockpiling Didn't Last

Huawei had stockpiled a large inventory of Kirin chips before the ban. But those reserves were finite. By the end of 2020, flagship phones like the Mate 40 series were already in short supply. The P50 series in 2021 used Qualcomm Snapdragon chips, but only 4G versions — because the US didn't allow 5G modems. Imagine a premium phone in 2021 that couldn't do 5G. That hurt.

Why No One Could Replace TSMC

Some ask: 'Why didn't Huawei use Chinese fabs?' SMIC, China's biggest chipmaker, couldn't produce chips at 5nm or 7nm. The technology gap was huge, and the US also pressured equipment suppliers like ASML. So Huawei had no backup. This dependency was a strategic mistake — a lesson many companies are now learning.

Google Services Gone, App Ecosystem Broken

The GMS problem deserves its own section because it directly killed Huawei's consumer sales outside China. Before the ban, Huawei had a chance to build its own app store, but the ecosystem was years behind the Google Play Store. Without GMS, Huawei phones couldn't run banking apps, ride-hailing apps, or even games like PUBG from the official store. I tried using a Mate 30 Pro in 2020 — I had to hunt for APKs on forums, and many apps complained 'Google Play services is required.'

HarmonyOS as a Lifeline

Huawei pivoted to HarmonyOS, launching it on phones in 2021. But HarmonyOS still relied on Android Open Source Project code, so it wasn't truly independent. And adoption outside China is almost nil because the same app problem persists. Huawei's AppGallery has grown, but the number of high-quality apps is still far smaller than Google Play.

Global Trust & Market Access

The US campaign against Huawei wasn't just technical — it was about trust. They alleged Huawei's equipment could be used for espionage. Huawei denied it, but the damage was done. Carriers in Europe, Australia, and Japan removed Huawei from 5G contracts. I recall reading a report from the European Commission that recommended member states assess Huawei's risk. That basically shut the door for Huawei in big telecom markets.

5G Leadership Turned into a Liability

Huawei was the leader in 5G patents. But being strong didn't help. Governments viewed their dominance as a threat, not an advantage. They blocked Huawei from bidding on 5G projects, forcing the company to focus on China and a few friendly markets like Russia and parts of Southeast Asia.

Consumer Business Freefall

The smartphone division took the heaviest hit. Huawei went from over 20% global market share in 2019 to less than 4% by 2022. I remember walking into a store in Singapore — the Huawei counter was almost empty, while Apple and Samsung were packed. The company had to sell off its Honor sub-brand in November 2020 to keep it alive. That was a painful move, but necessary.

Revenue Drop

According to Huawei's annual reports, revenue from the consumer business fell from 467 billion RMB in 2020 to 214 billion in 2022. That's a 54% drop. The problem wasn't ability — it was access. People couldn't buy Huawei phones easily in markets they used to dominate.

How Huawei Is Fighting Back

Despite all this, Huawei isn't dead. It's pivoted hard into enterprise solutions and cloud computing. I've seen their data centers in China — they're impressive. They also launched smart car components, partnering with brands like Seres and Changan. The company is leveraging its 5G and AI patents to sell licenses. Revenue from the ICT infrastructure business actually grew.

Can They Make a Comeback?

Maybe, but not soon. The smartphone business will remain crippled without advanced chips and GMS. However, if China can develop domestic chip manufacturing (which is improving slowly), Huawei could regain some life. But for now, the problem with Huawei is that it was too dependent on global supply chains and got caught in a geopolitical war. It's a cautionary tale for any ambitious tech company.

FAQ: What Was the Problem with Huawei?

Why did Huawei lose access to Google services?
Because of the US Entity List in May 2019, which prohibited American companies (including Google) from doing business with Huawei without a license. Huawei could still use Android open source code, but not Google's proprietary apps like Gmail or the Play Store.
What is the real reason Huawei can't make chips?
The real reason is that TSMC, which made Huawei's Kirin chips, uses American equipment and software. The US tightened rules in 2020 to block any chip made with US technology from going to Huawei. No other foundry could produce cutting-edge chips for Huawei at scale, especially below 7nm.
Did Huawei really violate US sanctions on Iran?
Huawei has denied violating US sanctions. In 2020, CFO Meng Wanzhou reached a deferred prosecution agreement with US authorities, but the company never admitted guilt. The US government's main accusation was bank fraud and wire fraud related to dealings with Iran — not the technical issues that later led to the ban.
How bad is the chip situation for Huawei now?
As of 2024, Huawei still cannot get high-end chips made for its smartphones. They use Qualcomm chips limited to 4G, or rely on their own Kirin chips manufactured by SMIC at a much older 14nm process. That's why new flagship phones like the Mate 60 series surprised many by having 5G again — reportedly using an SMIC-made Kirin 9000s chip at 7nm, though yields are low and performance lags behind current Qualcomm or Apple chips.
What was the biggest mistake Huawei made?
In my view, it was not building a strong enough app ecosystem before the ban. Huawei knew about the risks of geopolitical tension, but they assumed the US wouldn't go all the way. They also didn't invest in domestic chip manufacturing early enough. They put all their eggs in the TSMC basket. That overreliance was the fatal flaw.
