Owners of Samsung’s Galaxy A07, in both its 4G and 5G versions, are reporting widespread lag and intermittent touchscreen freezes after installing One UI 8.5. The affected phone is not a niche device: according to Android Authority, the Galaxy A07 is this year’s best-selling Android smartphone, and Samsung marketed it on the promise of six major Android version upgrades. Samsung has not publicly acknowledged the problem or promised a fix, although the 5G model has already received two follow-up updates, the latest described as improving stability. The cheaper 4G model has so far received only a security patch. Here is what is known about the issue, who is most affected, and what owners can reasonably do.
What you need to know
- Complaints center on two symptoms: general sluggishness in the interface and a touchscreen that periodically stops responding to taps.
- Galaxy A07 5G has received two post-8.5 updates, the latest promising improved stability; one owner reported on Samsung’s forum in August that the freezes had disappeared.
- Galaxy A07 4G has received only one update since One UI 8.5, in mid-July, containing the June security patch and no stability fixes.
- Samsung updates both models quarterly, so the next expected window is October.

Update problems on the Galaxy A07
A budget phone that outsold everything else
The Galaxy A07 is the cheapest phone in Samsung’s current lineup, and Android Authority reports it became the year’s best-selling Android device. Its hardware is unremarkable: a 6.7-inch 1600 x 720 display at 90 Hz, 4 GB of RAM, a 50-megapixel main camera paired with a 2-megapixel secondary module, and a 5,000 mAh battery. The configuration cited in the source is the 4 GB / 64 GB version.
This is a phone for people who need calls, messaging, banking apps and a camera that simply exists. Devices in this class sell in the millions and are rarely replaced sooner than three or four years after purchase.
Six Android versions as the main selling point
In the budget segment, Samsung sells peace of mind rather than specifications. The Galaxy A07 4G launched on Android 15 and is slated to receive six major system upgrades. For a phone at this price, that is unusual: Chinese competitors in the same class typically offer one or two version upgrades before the device is left with security patches only.

Retailers highlight that commitment in product listings, and it is what persuades buyers to choose Samsung over more powerful alternatives from Xiaomi, realme and others at the same price. The logic is straightforward: the phone should survive Android 17 and beyond, receiving new features and security fixes throughout.

The Galaxy A07 and its future Android updates
Long support has a downside that marketing does not mention. Each major update is a new version of the system written first for flagships and then adapted to weaker hardware. The more modest the processor and memory, the higher the chance that the next One UI release runs worse than the one before it.
Freezing touchscreen and lag after One UI 8.5
Owner complaints come down to two symptoms. The first is general slowness: apps take longer to open and the interface stutters. The second is more disruptive: the touchscreen periodically stops responding, and the display appears to freeze.

The workarounds users have found point to a software rather than hardware fault. One owner writes that locking and unlocking the phone restores touch input until the problem returns. Another reports that a factory reset did not help at all, which suggests the cause lies in the firmware itself rather than in leftover data from old apps.

The Galaxy A07 lags after installing One UI 8.5
Not everyone ties the slowdown specifically to One UI 8.5. Some 4G owners say their phones already became slower after One UI 8, with the latest wave of complaints arriving with 8.5. Owners of other Galaxy A0x-series models on Samsung’s current firmware describe similar symptoms, so this does not appear to be a defect confined to a single production batch.
5G model has already received fixes; 4G has not
The frustrating part is that the cheaper, higher-volume 4G model is so far getting less attention. The Galaxy A07 5G has received two updates since One UI 8.5, and the changelog for the latest one promises improved stability and reliability. In August, an A07 owner wrote on Samsung’s forum that the touchscreen freezes and lag had disappeared, most likely thanks to those patches.
The Galaxy A07 4G has received just one update since moving to One UI 8.5, in mid-July, carrying the June security patch. Its changelog mentions security only, with no reference to stability or display behavior. That helps explain why new complaints keep coming specifically from 4G owners. Samsung updates both models quarterly, so the next expected window is October.

Should you install the update, and what can owners do?
If you have a Galaxy A07 4G and it is still offering One UI 8.5, the source author suggests there is no reason to rush. The update brings no features worth risking smooth operation on low-end hardware, and Samsung does not provide an ordinary way to roll back. Waiting for the October update and checking whether its changelog mentions stability is the more sensible option.
If you have already updated and the screen freezes, the workaround reported by one owner is locking and unlocking the phone, which temporarily restores touch input. Another owner says a factory reset did not resolve the issue.
What remains uncertain: Samsung has not confirmed the problem or committed to a fix for the 4G model, and the improvement on the 5G version rests on a changelog and one owner’s report rather than an official statement.
For anyone still choosing a phone, the story does not fundamentally change the calculation: six Android versions at this price remains a rare offer. But it does show that long support is not only a benefit — it is also an obligation for Samsung to repair what its own updates break. How quickly the company addresses the 4G model will show what that promise is worth in practice.
