My phone has developed some really concerning smartphone display issues. There's a green tint on the left side of the screen, and it flickers occasionally, especially when brightness is low. I have a OnePlus 8T that's about a year old. The problem started about two weeks ago and has been getting progressively worse. I've tried adjusting display settings, changing refresh rate, and even did a factory reset, but the smartphone display issues persist. Is this likely a loose display cable, a failing screen, or something with the graphics chip? Has anyone had similar smartphone display issues and managed to fix them, or is screen replacement the only option?
Smartphone display issues with green tint and flickering are classic symptoms of a failing OLED screen or loose display cable. OnePlus phones use OLED displays which can develop these problems over time. The fact that it's getting worse suggests it's hardware, not software. It could be the display itself failing, or the connection between the display and motherboard. This usually requires screen replacement, which can be expensive on OnePlus phones.
Try applying gentle pressure to different areas of the screen while it's on. If the smartphone display issues change or temporarily fix when you press certain spots, it's likely a loose display cable. You can try opening the phone and reseating the display connectors. But be careful - OLED displays are fragile. If you're not experienced with phone repairs, this could make the smartphone display issues worse.
Check if the smartphone display issues are temperature related. Some OLED screens have problems in cold temperatures. Does it get better if the phone warms up? Also, try changing the screen resolution and refresh rate in settings. Sometimes driver issues can cause these smartphone display issues. If changing settings affects the problem, it might be software related.
OnePlus has had known smartphone display issues with green tint on some models. Search online for your specific model - there might be a known manufacturing defect. Some users have gotten free replacements even out of warranty because it was a widespread problem. Contact OnePlus support and mention the green tint issue specifically - they might have a repair program for these smartphone display issues.
