Anyone else getting repeated keys AND keys out of order?  I can type something like APPLE and it may come out APPELL.  Most certainly software, and not just the debouncing issue I described that can repeat keys.

And I also have experienced severe lagg (that extra "g" was a repeated key for real) where the keyboard input is several seconds behind.  It seems to happen a lot faster when I Copy and Paste web text.  I have to wonder if this is due to a keylog file that we don't know about.  Because, unlike the repeat issue, that problem is always resolved on a reboot (so maybe a new log file is created from scratch and there is no delay for a while????)  Just a thought of what else to explore in endless amounts of flawed code...

Indeed, but wasn't that something that's been reported very early and also fixed in the first stock Android update?

That sounds like something eats up the processing power, so it is unable to process the keystrokes in real time.
But obviously what ever does the processing should have had sufficient priority for this not to happen normally.

Anything you are aware of running in the background that might be what is disturbing. E.g. some complex sound decoding, playing high-resolution sound?
I would try to install something like GSam or the like, to find out what is using the resources. (GSam registers the battery pull over time, but any substantial CPU activity should also leave a mark in the power consumption). It MIGHT be something that it is OK got a higher priority than the keyboard.

To make it do it's best, make sure to give att to see the battery statistics. (for the version paid with money/ads respectively)

adb -d shell pm grant com.gsamlabs.bbm.pro android.permission.BATTERY_STATS
adb -d shell pm grant com.gsamlabs.bbm     android.permission.BATTERY_STATS

I think it is temperature related: on a hot, sunny day I get almost every key doubled. And it never happen with software keyboard input which shoud have same processing priority.

I would be surprised if the handling of the physical keys and touch are not substantially different, so do not think we can deduce from differences between the two.

Same issue here. double "e", sometime no "d" or "a" and now and then the keyboard lags (words displaying on screen 3 to 4 words behind what I'm typing).

...

Both issues described above not happening constantly, so this makes me think they are both software issues.

I monitored CPU usage for a bit, but as of now, I couldn't pinpoint an app that bottlenecks the CPU.

I have found that a reboot always fixes the severe lags, where it outputs like 1 character a secondd, but nothing helps those repeated keys like you just saw, because...  I'll say it again...  there's something in the Software where it's not sampling and debouncing the keyboard fast enough, regardless of moderate physical degradation to the keyboard.

The lag issue is confusing, however.  I have to wonder if there's a keylog being created every time the device reboots, and it gets to be so huge, that writing keystrokes to the log file takes priority to them actually being output to the application layer, and we experience this huge lag.  I notice this lag occur more quickly when I copy and paste web content into a text editor.  Perhaps because there is just such a huge amount of text going into a log file, and then typing and adding one more character at a time takes a lot of time to open, modify, and save the file ever time a key is pressed???

And no, I wouldn't expect any bottlenecks - it has more to do with How the data is being processed and passed around, not CPU speed.  After all, it's only a few keystrokes a second (other than the time proper debouncing takes).  We need someone to dissect the f#@& out of parts of these OS's that Nobody seems to be familiar with, and unfortunately, I just don't have the time to explore that.

I agree that it sounds like a software priority issue. But rather than lack of priority I would guess something else having too high priority thus interfering with the keyboard operation, as not everyone reports it. But could still be a system isssue, where some other system stuff gets activated by some actions or apps not all use or use the same way.

Starting with the ones power consumption points at as posssible culprits, I  would try to stop (or even deactive/uninstall) stuff and see if whatever triggers the phenomenon can be narrowed down.

Ultimately trying a factory reset, and test for the issue before reinstalling/restoring.

Are you guys still on stock? Try switch to Lineage OS. I've have had micro lags issues on stock but not on LOS.

I have had issues on both LOS and AICP. Haven't tried stock for ages though. But I have to say that incidence of those strange issues when keyboard suddenly provides some strange characters, usually including a number inside a word, did decrease greatly when I switched to AICP.

When typing very fast, and perhaps having more than one key down at a time, there are N-key-rollover issues. Could that be the issue? And if I remember right, it was @TDM that made a new variant of the keyboard-driver that improved this for Lineage 16 (that I assume is still in use on 18 and AICP)

Right, the new driver should has less issue.

Anyway, I also experience this under LineageOS 18.1, maybe mostly 'n' key what appears for me as "ghost" key on my QWERTZ layout, I think that is 'b' on shifted QWERTY.

Not in my case at least. I usually get double a, l, o etc.

edit: my device is QWERTY

I have had the same problem for a few days. Sometimes it seems to me that the leather / fabric cover is statically charging the display and causing the effect. When you slide it out of the case, the typing starts. Strange... 😕

This could make a LOT of sense. If I try to operate the Pro1 with a cheap slow charger that is not grounded, I see the issue too, but never unplugged nor plugged to a grounded device like the PC. And surface currents and static electricity is sort of related, being (relatively) high voltage and low current.

Aah. Okay ... well, I'll stay relaxed and take it as a lovable character trait of the device and still change the case 🙂
