I first realised bright spots could actually spread while using a phone late at night in a small flat in East London. What started as a faint pale circle near the bottom edge slowly expanded over a few months. At first, I blamed my eyes. Then I compared screenshots. The spot wasn’t in the screenshots. That was the moment it became clear: this wasn’t software, and it wasn’t static.
Many smartphone users across the UK ask the same question once they notice a bright or white patch on their display: will it stay the same, or will it get worse? The honest answer is uncomfortable, but important. In most real-world cases, bright spots do spread over time, and understanding why helps you decide what to do next.
When people talk about a bright spot spreading, they usually mean one of three things:
All three happen in real usage. I’ve seen users in Manchester insist the spot “moved”, when in reality the damaged area expanded outward as surrounding pixels degraded.
Smartphone displays are layered systems under constant stress. Even when you stop using the phone heavily, time alone continues to affect damaged areas.
The main reasons bright spots change over time are:
Once a display has been compromised, it rarely stabilises completely.
Pressure-related bright spots are the most likely to spread.
Here’s why: pressure distorts internal layers, but the damage isn’t always clean or contained. Micro-deformations remain inside the panel, and every time the phone warms up, those areas expand slightly.
I’ve seen this repeatedly with users in Birmingham who commute daily and keep phones in tight pockets. Even after the initial bright spot appears, continued pocket pressure causes the affected zone to slowly widen.
This is especially common on LCD screens, where backlight diffusion layers are easily disturbed.
Yes, but differently.
OLED bright spots usually spread because surrounding pixels degrade faster than the already-damaged area. The result is visual expansion, even if the original damaged zone stays the same size.
Common OLED-related triggers include:
Users in Leeds on networks like EE and Vodafone UK often report this after extended video streaming or hotspot use.
Heat doesn’t usually cause the first bright spot, but it accelerates spreading.
Real-world examples I’ve encountered:
Heat weakens adhesives and accelerates chemical ageing inside the display. Once a spot exists, heat helps it grow.
Indirectly, yes.
High brightness increases power draw and temperature, especially on OLED panels. Over time, this speeds up uneven pixel wear.
Several users in Nottingham told me they only noticed the bright spot spreading after switching to maximum brightness during winter, when indoor lighting is low.
Moisture-related bright spots are unpredictable.
Water can leave mineral residue inside the display layers. As the phone heats and cools, those residues alter light diffusion further.
I’ve seen phones used outdoors in Sheffield develop expanding bright patches weeks after light rain exposure, even without full water damage.
Sometimes, but only under specific conditions.
A bright spot is more likely to stabilise if:
However, “stopping” usually means slowing down, not reversing. I’ve rarely seen a bright spot remain unchanged for years.
They can’t. Updates may change colour curves, sometimes making spots less noticeable temporarily, but they don’t repair physical damage.
These apps don’t affect backlight diffusion or pixel ageing. I tested several while travelling between Reading and Oxford on O2. None slowed the progression.
False. Many spots remain subtle for months before suddenly becoming obvious.
A user in Bristol noticed a tiny bright dot near the top of the screen. Six months later, it had turned into a noticeable oval, despite careful use.
Another user in Coventry ignored a small bright patch until resale time, only to find it had expanded enough to significantly reduce the phone’s value.
In both cases, spreading wasn’t dramatic day-to-day, but obvious over time.
You can’t undo the damage, but you can reduce how fast it spreads:
This approach buys time, especially if you’re planning an upgrade.
If the bright spot is spreading and distracting, replacement is the only permanent solution.
From repair shops in London, Leicester, and Derby, the advice is consistent:
This is the point many experienced AvNexo users reach after trying to live with a growing spot.
Yes, in terms of functionality. Bright spots don’t usually affect touch or performance.
But visually, they almost always become more noticeable. UK buyers are particularly sensitive to screen flaws, which affects trade-in and resale options.
Bright spots are not static defects. In real usage, they behave more like slow-moving damage.
Based on long-term device testing and user feedback analysed for AvNexo, the pattern is clear: once a bright spot appears, it either stays mildly annoying or slowly spreads until it becomes impossible to ignore. The difference is how quickly you act.
If you understand the cause and adjust how you use the phone, you can delay the worst effects. But if perfection matters, replacement is the only true endpoint.
