Phone Acting Funny After Sticking on Rfid Sticker
- #1
also my Sim card most of the time now isn't detected and other times it is detected totally random as well for god knows why !! I don't know what the hell is up with the phone but it's just the first time to have such a thing happening to me..
I didn't root it, didn't download any unsafe apps ,and didn't do anything unusual with it. just out of no where started acting weird..

It got really bad. I returned it to xiaomi, with footage of it refusing to start
They emailed me a video of their person restarting it. I explained again that it was an intermittent fault, but they just returned it me (after asking me whether it not I wanted it back!) I was without it about 6 weeks in all
It arrived, working.initially, and within 24 hrs it had shutdown again and continued to do so
Frustrated I took the back off, took it all apart and found that the antenna connection was a bit loose. Pressed in all the plugs (screen, battery etc) and screwed in the retaining plate good and tight. Put it all back together
Bingo!
No shutdowns since!
Took about 45 minutes and a steady hand
Can't be sure if it will work for you, but it's got my phone working again
Edit:
Just noticed your other post, mentioning recurrent reboots - all sounding quite consistent with my experience... Just saying
There are some good teardown videos on YouTube!

you have to be more specific with ROM, version, vendor version, Magisk Version, kernel details !
if MIUI ? then which version / built/ cn / Dev ?
I didn't change the rom so it's miui global 10.3.8 stable and the kernel version is 4.9.112-perf-g4aff1b2

mine would just keep locking the screen it doesn't restart or shutdown and refuse to open. gonna try to reset the phone before I try to tear it downThis kind of thing was happening a lot with mine, for no obvious reason. Stock rom. Also unprompted shutdowns, sometimes refusing to restart (for weeks at a time!)

Xiaomi technical service is just trash. and I don't have warranty so it will be even harder.
btw the other post was for another phone.

Absolutely - I'd recommend resetting a few steps ahead of getting out the screwdriver!
