A symptom is only useful if someone can tell you what it means and whether it is checkable. That is what this table is: community-reported shapes, written down as a cause and a verdict on whether we can see it.
Over 90 天 we read 2102 posts from r/OculusQuest / r/PicoXR / r/VIVE through a public archive, of which 532 were help requests. We read the bodies and the replies, not just the titles, and only kept the shapes where a reply named a cause or a fix that someone could repeat.
| Community | Posts read | Help requests |
|---|---|---|
| r/OculusQuest | 1800 | 432 |
| r/PicoXR | 229 | 100 |
| r/VIVE | 73 | 0 |
社区样本只说明「有人这样坏过」，不能当地故障率；官方口径与出货量不在这里。凡是只出现一次的个案，标 sample=1 并且不对外当结论。
Meta Quest Quest 2, Meta Quest Quest 3, Meta Quest Quest 3S
What it usually means社区里这类现象集中在固件版本切换之后；同一个版本有人中有人不中，说明与设备当前状态有关而不是批次缺陷。高票经验是先让它进恢复流程，再重装同一版本。
Can a check confirm itNo — the device never answers. A headset that will not boot cannot report anything, so any claim about it would be a guess. We read 设备不回话，读不到任何字段.

What it usually means维修从业者在帖子里判断为面板或排线问题，不是软件；菲涅尔镜片的分层纹路容易被误认为故障，所以要先确认线条是否随画面内容变化。
Can a check confirm itNo. Nothing in a read-only interface exposes this; it is decided by looking at the symptom. We read 面板缺陷读不出来，只能看现象.

Pico Pico 4, Pico Pico 4 Ultra
What it usually means帖子里的结局是充电口损坏，只能换口；但在此之前几乎所有回复都先要求排除线材与充电器。
Can a check confirm itYes, from the host. A read-only ADB command on a connected host shows it directly. We read 电流值：插着却读到 0 或仍在放电.

Meta Quest Quest 3, Meta Quest Quest 3S
What it usually means高票回复一致指向保护性关机与传感器，而不是散热膏：现代 SoC 过热会先降频再强制关机保护硬件。把「过热」当成死机原因，会让人去拆机，方向就错了。
Can a check confirm itYes, from the host. A read-only ADB command on a connected host shows it directly. We read thermal status 与最热热区温度.

What it usually means求助帖里占比最大的一类是 PC 串流，而回复最后落在路由器、编码器、后台程序（Xbox Game Bar 一类）和主机性能上。把头显当故障源是最常见的误判。
Can a check confirm itYes, from the host. A read-only ADB command on a connected host shows it directly. We read 能排除头显侧因素：热状态、可用内存、当前刷新率.

What it usually means第二大类求助。漂移多数是摇杆磨损或校准，追踪丢失多与光线、镜面反射、电池电量有关。
Can a check confirm itYes, over HID. Reading the HID input reports while it is plugged in shows it. We read 接电脑时读 HID 输入报告的间隔与数值跳动.

What it usually meansPico Connect 一侧锁了刷新率；帖子里的解法是关掉透视后再进，帧率回到 90。这类「非整数的帧率」是主机协商出来的，不是面板能力。
Can a check confirm itYes, from the host. A read-only ADB command on a connected host shows it directly. We read 那块显示当前报的 renderFrameRate.

What it usually means社区定位到「Speed Sense」这个显示选项，关掉后消失。它属于设置层，不是面板坏。
Can a check confirm itNo. Nothing in a read-only interface exposes this; it is decided by looking at the symptom. We read 闪烁是时序现象，adb 侧读不到；但能读到当前刷新率是否被动态调节.

Pico Pico 4 Ultra, Pico Pico 4
What it usually means回复指出瓶颈常在线的载流能力，而不是充电头功率。无线串流本身耗电大，边玩边充只能减缓掉电。
Can a check confirm itYes, from the host. A read-only ADB command on a connected host shows it directly. We read current_now 的正负与大小.

Pico Pico 4 Ultra
What it usually means回复把它定位到主机侧：后台程序（Xbox Game Bar 一类）、网络设置、以及编码器。码率降到最低仍卡，说明不是带宽问题。
Can a check confirm itYes, from the host. A read-only ADB command on a connected host shows it directly. We read 头显侧热状态与内存，用来排除设备本身.

What it usually means一体机的共同问题：边界数据与使用环境绑定，换了房间或光线差就会丢。这一条不是硬件故障。
Can a check confirm itNo. Nothing in a read-only interface exposes this; it is decided by looking at the symptom. We read 边界数据在设备私有存储里，只读命令读不到.
Meta Quest Quest 3, Meta Quest Quest 3S, Meta Quest Quest 2
What it usually means这个口同时承担充电和 PC 串流，反复插拔是消耗件。社区里最受认可的做法是加一个 90° 转接头当牺牲件，而不是每次直插。
Can a check confirm itNo. Nothing in a read-only interface exposes this; it is decided by looking at the symptom. We read 接口机械磨损读不出来；但断链会在会话里表现为超时.

What it usually means样本量很小（r/VIVE 90 天里没有一条求助类帖子带 support flair），只能作为线索登记，不能当结论。
Can a check confirm itNo. Nothing in a read-only interface exposes this; it is decided by looking at the symptom. We read 样本不足，还没有形成可复现的判定规则.
Three of these shapes are readable from the host without touching the headset: thermal throttling, an unusual refresh rate, and a charger that is connected but not charging. The ADB check prints all three, along with the display the headset appears as and where sound is routed.
It is not a failure-rate table. Community reports tell you that a failure shape exists and roughly how it is being solved; they cannot tell you how many units are affected, because nobody posts about the headset that worked. Where our sample was too thin we say so instead of filling the row.
If your symptom is missing here, that is worth telling us: run the device check and send the reading. New rows in this table come from readings, not from other people's blog posts.
