My Jiayu F1 autofocus stopped working, it is locked in macro position.
Restoring the factory settings, but that did not help.
Can someone help, other working well?
Not even Custom Rom installation did not help.
In addition, a front camera focus does not function .
It would be nice if I could help my problem !
Hi, I´m having the same problem here.
Did not find anything on the internet regarding this, only a topic in a russian forum that I am preety sure that talks about this problem and how to fix it, but the translated version of the instructions did not came very clear, so I did not tried to do.
If someone could understand and do it, and post the instructions in english, I will be very happy.
I cannot post outside links, but to find the topic just search in google for "Jiayu F1 focus". The forum is

hi guys
i solved same problem few months ago. problem is with camera module. lens is screwed out of range. so you need open the phone and manualy screw lens back to the right place.
Yes, lens is pulled out, i screw it back, but still same problem.
Maybe then I will be without a camera....
I need to tell you my short story with the Redmi Note 9S.
I bought the phone at the beginning of may, my first Xiaomi with MIUI (my former phone is also a Xiaomi, but a Mi A1 with Android One) The first two weeks was working OK. I even red some reports about wifi and screen shadows bugs, but my phone didn't show these issues. I was very satisfied with the camera, the speed, and the amazing battery life.
However, around 20th of May it started with wifi disconnections with the screen off, almost every time that screen went off, the connection stopped. I assumed this bug was normal in a recently released device, and that it was going to be solved on the next software update.
Also, one of my smartphone main use is listening to music, through Bluetooth because I have the excellent Sony 1000XM3 headphones. Sadly, I discovered that my headphones, that sounded so good paired with my former Mi A1, sounded very very low with my brand new Redmi Note 9S. At full volume at the phone it sounded low with lack of punch and liveliness. Also, I was surprised that my dad's Redmi Note 8 showed the same behavior when I connected my headphones. So, I suspect from MIUI implementation.
The end of May came and so the first software update to my RN9S. I upgraded quickly thinking that the wifi bug was fixed, and the first days that was my impression. However, around the 8th of June it started again with the random disconnections -less than before, I need to say-.
Also, the Bluetooth bug wasn't fixed, even having informed Xiaomi about it, on official forums and through the feedback app. They requested me to send a logcat, with no further response.
Last weekend I installed the latest update, 11.0.9.0 QJWMIXM, hoping that, after two updates, the bugs was finally fixed. But no, there is no fix at all. Also, on official forums team members are saying that this update will be the last until MIUI 12, probably out in July.
Due to COVID pandemic, I'm working from home, using Whatsapp Desktop to communicate with my workmates. As you may know, WD need to have the phone permanently connected. But with this annoying bug, WD doesn't work, and I received the messages late.
So, frustrated with bad Xiaomi support, and problems with brand new device, I ended selling it, and now I'm going to buy a new, non Xiaomi phone. Luckily I still have my old Mi A1 as a backup, no MIUI of course.
I DON'T RECOMMEND TO BUY THIS DEVICE NOW, UNTIL ALL BUGS WILL BE FIXED.
Hope my short story serves as a warning to buyers, and a wake up call to Xiaomi. Care about your phones and your customers.
my experience, dont touch a Xiaomi phone unless its been out in the market for atleast 6 months.

A very good point. I also feel that I bought this phone too early, and we are all sat here wondering if the major bugs on our phones are going to be fixed. I won't be too hasty next time, I'll probably purchase something else too.
I am very happy with my purchase.
Consider installing a custom rom. I have not noticed any bugs + much more useful than MIUI: https://forum.xda-developers.com/redmi-note-9-pro/development/rom-evolution-x-ganja-curtana-t4094495

That's what my plan is, I love the phone but very disappointed with stock support. What amazes me is that the custom Rom devs can produce a custom build without the bugs, yet Xaiomi don't see these major bugs as a priority.
I really want to flash Evo X, but I want to make sure I do it right. At the moment I am reading about bootloops with some people that have tried it.
Sorry if this is off topic here but what were your exact steps flashing the Evo x ROM. Just bullet points will be fine.
I'm rooted with Magisk. I just need to be rid of these bugs once and for all.
First of all a disclaimer, the source code for TWRP for Note 9S has not been published. It may contain some malware or anything else. I am not responsible for any damage. I just tell what I did and it worked for me. Might not work for you.
PC is required to do the following:
" unlock bootloader
* update to MIUI v11.0.7, I got a fixable bootloop on other version (search MI forums or similar for the files. Update from system menu did not work for me)
* turn off phone
* enter fastboot with volume down + power
* install TWRP (search MI forums)
* copy Evolution X install file to SD card
* follow the instructions in Evolution X thread
The problem is that Miui Global is a terrible operating system, really horrible. Don't expect improvements with Miui_12.
Or wait for roms based on Pure Android (AOSP / LOS) or if you want to keep Miui raisins for rom Xiaomi.eu

Have you even read what he wrote?
I have had my Redmi Note 9S since mid-May. No issues like that all for me thus far.
No problem like the one you describe.
The sound is great. If it was low for you (as it was for me when i first connected my earphones) you must use both the phone and earphones volume slider to increase the sound.

I could not finished up the epistle you wrote describing the issues you have experienced, but i'll say in my opinion that you are still new to MIUI, being an old miui user, there a settings that make the phone disconnects network connectivity either WiFi or Mobile data in other to save battery, Check settings- battery performance - and play around the options there. Cheers
Well yeah, but the wifi bug definitely EXISTS.
Read through the different boards and you will see how many users noticed the same behavior on their devices.
That's NOT a wrong setting that you simply can switch in the energy save settings of the phone.
And Xiaomi knows about this bug and they tried to give a fix in the latest firmware update, but for many it's more a "dirty workaround", cause wifi is still disconnecting after few minutes in idle, but reconnects after a few seconds in most cases. Its a dirty workaround, cause the constantly reconnecting all few minutes is draining battery unnecessarily and doesn't always work.
(Would be nice not to quote such a long post...its a bit annoying to scroll all the time to come to the new post itself ?)

Source your quotes. Where are you seeing that this is a common thing. This is the first I've read of it on 2 forums. I was also going to suggest the wifi to mobile handover setting as that has plagued me in the past because of my bad wifi.
Lol...are you kidding me?!?
You don't have to go far...a closer look HERE on XDA and you'll find the first thread with over 200 posts so far...!
https://forum.xda-developers.com/re...omi-redmi-note-9s-wifi-stops-leaving-t4085213
And by the way, even Xiaomi themselves have posted that the update to MIUI 12 will "Adress the wifi issue"...
My short story with the 9S:
I did order the 9S 4/64GB with Gshopper on aliexpress, shipped from the Czech Rep.
It was really shipped from Germany (JKGC in Buchholz).
Now the trouble started:
- MIUI 11.0.7 Inserted SIM - data works, outgoing calls all go to "Emergency Number"
- unlocked BL and installed TWRP and crDroid - still data works, but all calls go directly to 112/911...
- flashed with MIUI the fastboot MIUI 11.0.9 - still the same...
- unlocked BL again and flashed TWRP and MIUI 1.0.3 EEC - still no call other than "Emergency Number"...
- Flashed Evo X - still no call other than "Emergency Number".
In Settings/Apps and../Phone the check box is ticked, so unfortunately this was not the problem.
Gshopper denies Warranty, only agrees to refund if I pay for return shipping and says I can buy a "new" 9S. Even that they sold a faulty product shipped from the EU(CZ) to EU(IRL)...
EDIT: found a partial fix, see here: https://forum.xda-developers.com/showpost.php?p=83114093&postcount=2
I just got this phone and am pleased with the hardware and performance coming from a Zenfone Max Pro M1 but it does seem a bit buggy (random app freezes a couple times, and some games like Sonic the Hedgehog 1 and 2 refuse to start). Hopefully these get patched quickly but I will probably use a custom ROM once updates cease.
Is the WiFi bug a problem in every phone or just some of them?
If it's just say 10% of phones then I don't mind taking my chances.
If it's every phone then it's not worth it.

Well, I guess you can have the problem with every device of this model.
It more depends on the combination of the device and the router you are using.
Most of the users facing problems are using a fritzbox router as far as I know.
I'm using a router from vodafone for example, and have no bigger problems with wifi on my phone.

I use a "Vodafone" router too, a Huawei HG556a and openWRT. No problems to use the hotspot and "relay" the Inet to my home network.
In my case I had to downgrade to 11.0.7 first and then install crDroid. After that WiFi and hotspot worked, which it didn't with 11.0.9 as base. I tried LOS from telegram and that worked well from 11.0.9 as base.
Trying to keep the story short:
I, by mistake, deleted the whole internal storage of the mobile. When I connected it to the computer, all I saw was some folders with strange and long names like /(&^+'(^&FSG%('!645416+'. Of course not this, you got the idea. Then I kinda formatted the storage, and was left alone with TWRP.
Ever since, my wide angle and front cameras don't work. I reverted to stock Xiaomi ROM an hour ago, yet it was also problematic: While the program said it is still being flashed, the mobile rebooted. Still, now I am on stock ROM, maybe with limited "fix", and with stock ROM I cannot use these two cameras as well.
Before reverting to stock ROM, I tried,
Different custom ROMs (including Paranoid Android, Pixel Experience, LineageOS, and crDroid). The issue was not solved with any.
Permissiver, hoping that it is a permission issue. Yet nothing changed.
trCam to see if it is because of the "number" that the apps try to connect to the cams. Again no luck.
I checked with Camera2API, and it shows only two cams (back main and front). It is okay, I am told, yet am unsure.
Strangely while these two don't work, macro does work - both in stock camera and GCam. I'd prefer no macro but front and wide but it doesn't ask me.
Any ideas?
Thank you in advance for your replies - if there'll be any.
