Some Galaxy S22 Ultra users fixed network issues by replacing Flex cable and Sub board

If you’re the proud owner of a Samsung Galaxy S22 Ultra but your phone is having a bit of an identity crisis jumping from 5G to LTE to “No Service,” you’re not alone. Despite being described as a “low-signal beast,” users have been sharing their frustrations about their Galaxy S22 Ultra’s network connectivity issues for months now. It’s like the phone can’t decide where it wants to land, bouncing between full connectivity to emergency calls only — and everything in between. Unfortunately, these issues persist even with the most recent One UI 6.1 update, perhaps suggesting that software may not be the culprit.

Samsung hasn’t officially acknowledged the problem, but here’s the good news: several savvy users have managed to fix their Galaxy S22 Ultra network issues, and the solution isn’t buried in the settings menu. Spoiler alert: you might need to get your hands dirty or, better yet, find a good technician.

The main issue here is that the Galaxy S22 Ultra seems to have trouble maintaining a stable network connection. Users have reported that their phones randomly drop from 5G to “No Service,” then hop back to LTE, and maybe settle on H+ for a while before losing service again. It’s an unpredictable mess, and it’s been driving users up the wall.

The usual fixes — toggling airplane mode, rebooting the device, or fiddling with network settings — only provide temporary relief. Despite their best efforts, the problem won’t go away.

Here’s where it gets interesting. A number of users have reported success by replacing specific hardware components within their devices. These components include the Flex cable, Sub board, and antenna. While it might sound like a major operation, for those who dared to take the plunge, the results have been nothing short of miraculous.

What’s the deal with these parts? The Flex cable is a ribbon-like connector that links different components within your phone. The Sub board houses critical connections, including those that control charging and, yes, network signals. The antenna is self-explanatory — if it’s faulty, your phone’s ability to catch signals goes haywire. However, S22 Ultra units in some countries don’t have it, so you’ll only change the other two components.

Let’s break it down. Users who’ve managed to get their phones back in working order didn’t just rely on software updates or a stern talking-to. Instead, they took their phones to a Samsung Service Center and had the faulty parts replaced. One user reported that after getting their Flex cable and Sub board swapped out, their phone’s network issues were history. They even tested it by wandering around their neighborhood and riding a motorcycle — no signal drops.

If you’re still under warranty, you might be able to get these repairs done for free. But even if your warranty has expired, it’s worth contacting Samsung support. Some users have managed to get their repairs covered as a “one-time courtesy,” while others were offered discounts.

However, be prepared to negotiate. Samsung’s customer service might first try to offer you a trade-in or a pricey repair. Stand firm, mention that this is a known issue, and you might just get lucky with a free fix.

Feeling adventurous? If you’re comfortable with a little DIY, some users have gone the self-repair route. They ordered the necessary parts — Flex cable, Sub board, and antenna — online (Aliexpress seems to be a popular choice) and replaced them themselves. According to these users, the repair isn’t overly complicated and can be done with a basic toolkit. The cost? About $5 per part, making this a budget-friendly option if you’re out of warranty and handy with a screwdriver.

It’s worth noting that Samsung hasn’t officially acknowledged this issue. This means there’s no widespread recall or free repair program (unless you get that lucky “one-time courtesy” fix). The problem seems to be a manufacturing defect — perhaps imperfect solder joints or faulty connections within the device. But without Samsung admitting fault, the best course of action is to take matters into your own hands.

If your Galaxy S22 Ultra is still within warranty, head to your nearest Samsung Service Center and get it checked out. If not, consider a DIY repair or push Samsung’s support team for a free fix, especially if you can reference the experiences of other users who’ve had their repairs covered.

That said, if your Galaxy S22 Ultra is giving you the runaround with its network connectivity issues, don’t give up hope. Whether you’re under warranty or out, there’s a fix out there –be it through Samsung or a little DIY magic. Your phone should be a reliable companion, not a source of constant frustration. So, take action, get those parts replaced, and enjoy the reliable, stable connection your flagship device was meant to deliver.
