Well, here goes a blogspot with actual content about the X3s I got, I suppose...
And thanks to the viewers for the 100k views!
Interchangeable parts on the Poco X3 series
When I obtained the X3P, I would never realize that it would have some issues with the display, such as dead touch zones on some parts on the corner
& most, if not every screen protector attached on the display ends up having some issues with sticking itself to the display (27/8/2021 Update : another attempt at attaching a hydrogel screen protector ended up successful). However, almost 3 months of using it & having to contend with said issues eventually drove me mad enough to take apart both the X3N & X3P, despite the X3N not having issues with the display - all in order to see if the X3P could use the X3N's screen. Here are some results I found.
- Modules traded with each other & are confirmed to work :
- Earpiece / front speaker
- The buttons, including the fingerprint scanner
- Vibration motor
- SIM/microSD tray (not the reader themselves, which are soldered on the motherboard)
- Modules not traded with each other :
- Bottom speaker
- Daughterboard with the charging port & headphone jack
- The connector cable for motherboard & daughterboard
- The cameras
- Current result after more than 24 hours (23/8/2021) (replacements done at 22/8/2021, 12:00 GMT+7) : So far, the X3P isn't exhibiting any issues with touch. However, neither does the X3N - despite using the X3P's "troublesome" display.
27/8/2021 Update : The touch issues on the X3P returns - Xiaomi / Poco might have used a questionable software touch driver for the X3P (probably to make it look terrible before the already terrible Poco F3 & Mi 11 series), while leaving the X3N with a decent one (probably because despite the availability of the "better" Redmi Note 10 Pro, Xiaomi / Poco somehow couldn't be bothered to downgrade the X3N's drivers).
28/8/2021 Update : Somehow the touch issues aren't present on MIUI (xiaomi.eu). Tested MIUI version is 220.127.116.11.
15/9/2021 Update : No Gravity Kernel somehow (mostly) fixed the touch issues I had. Welp, credits to NGK's devs!
Mounting partitions as rw
Finally found a solution to mounting partitions as rw in TWRP for dynamic partitioned PDAs like the X3P (maybe X3N as well, if not using brigudav's TWRP with the convenient mountrw script). The workaround is listed below. (27/8/2021 Update : A slightly more detailed guide is available here.)
- In TWRP, browse to Advanced > Terminal.
- Type in "mount -o rw,remount (a partition to modify)".
For example, to modify /system, type "mount -o rw, remount /system_root" .
Got too hooked into playing Skyrim on Windows, so I'm probably not going to be able to update the site every now & then. Well, here's hoping there's custom ROMs worth trying out as well...
