Enabling USB debugging only still doesn't work
Enabling both USB debugging and USB debugging (security setting) also doesn't work

I just tested again with usb wireless mouse, poco F3 doesn't detect it. When I tested on my samsung tablet, it's working right after I plug in the dongle with type-c adapter. Also, if I connect my phone to my pc, using the original usb cable, my pc also doesn't detect the phone

Any ideas? 

Still doesn't work for me. Btw, does yours working fine?

EDITED: After factory reset and connect to my pc and laptop I saw this error message on windows10 and it still doesn't detect the phone, maybe the data pin on the type c connector is faulty. The otg function also still didn't work

Yes sure I have enabled it, I believe my current EU stock ROM does not support Digi voWifi due to missing MBN in the configuration (similar issue like other phone model/brands)

Anyone using smart devil anti blue light tempered glass?
The display will appear yellowish due to the TG, how should i set the display to lessen the effect?

yes, but i cant stand the yellow colour...i have adjusted to cooler colour, seems to balance it back now

Are you using F3? I received those UK & HK calls since last week. 3 times/day mostly evening. At the moment i use truecaller to block. Nothing i can do. I suspect Poco server kena hacked and our numbers were sold to these suckers.

Anyone had issue with tws on pocof3? Not sure why my fill t1 lite only play on one side. Used to be able play on both side. Tested the tws on other phone like Samsung and sony no issue just on poco f3. Mono audio is off also

U mean this right it's normal tho

I simply buy in Europe

I already contact Digi to enable VoLTE, that works. VoLTE always needs to be enabled from network side, while VoWifi depends only on the device.
VoWifi requires VoLTE to work first, that's the reason you experienced that.

In high rise LTE signal is not so good, so VoLTE keep dropping calls, VoWifi would solve this. I hope with next update I can change to global rom

I guess it is not the proximity that spoil. Because, all xiao mi device come with no physical proximity hardware but they use the virtual proximity solution that utilise the gyrometer and others.
The test is easy, play some voice message, and cover the phone, it wont turn off the loud speaker nor dim the display.
By this virtual proximity sensor, xiaomi actually save them a lot.

Need to disable that miui optimization when install vance manager. The moment u do that, the phone becomes laggy and shit. After install manager then activate back the miui thingie

.........I just realised Poco F3 and Redmi Note 9T have faulty wifi driver that caused battery drain after updating to latest firmware. If I turned off the Wifi, those phones practically can last few days before recharging is needed.
Been wrecking my brain over the sudden battery drain only to discover the wifi as the culprit.

With my new Asus AX86u router, I noticed the wifi client belonging to F3 and 9T doesn't enter PSM 802.11 Power Saving Mode at all even when idling. Compared to my Samsung M30s and M31 (and even ancient galaxy S4), Asus router will report those Samsung devices entering PSM immediately after no traffic.

With Wifi turned on and connected, F3 and 9T battery are drained within 12 - 15 hours while idling. 

Note: before updating F3 and 9T firmwares, there was no wifi battery drain. Tested with Asus AC2600, TP-Link AX50 and TP-Link A6 routers. Same issue.

Anyone with Asus AX router can verify if their Poco or Redmi with MIUI 12 can enter PSM correctly when idling?

Example :

[attachmentid=11074570]

Bought F3 and 9T few months ago together during 11.11 sales. Never update the firmware until last week.

I am using F3 and 9T as alarm clock with 10 minutes interval to wake me up in the morning.
Imagine my surprise when these two phones (fully charged) used to drop around 1% to 3% from 10 pm until 7am next morning suddenly drop 60% - 70%.

Note: F3 and 9T have no SIM. Running airplane mode with Wifi active only.

Betterbatterystats ---> doesn't show anything. No wakelock etc. F3 and 9T are spending 99% in deep sleep during those night sleep time.

If Wifi is turned off, then there is no serious battery drain at all and it is back to usual 1% to 3%.

Seriously?
How is ur setting?
Never experience that.

GOT IT. FOUND THE DARN ISSUE.

The issue is DTIM at router setting.
If the DTIM value is set more than 15, then the F3 and 9T wifi will never enter PSM.

Previously, uncle sets the DTIM value at 30 with beacon interval at 100 (default) for all routers uncle tested. The purpose is to save battery power by not sending DTIM too often to wake up the phone.

Using wireshark + adb, uncle realised F3 and 9T wifi drivers are waiting for DTIM message in period between 1 - 15. When phones don't receive the DTIM message in this period, it seems to "reset" the timer and ignore the subsequent DTIM message that tells the phone wifi to enter PSM.

Basically, when the F3 and 9T wifi drivers don't receive DTIM in certain time period, the wifi chip will never enter power saving mode.

Strange that other android and apple devices plus laptops don't have issue with high DTIM value.

Hi guys,any suggestion for TP for poco f3?
