After finished the intial setting of phone, a black dot appears at the corner of the screen. It hasn't been there yet before the setting.
Although it does't affect any funtion in the phone, it makes me feel bad to have an black dot at the screen.
If I don't want to reset the phone again, what else could I do to remove the black dot?

that is VERY bizarre. i would factory reset (sigh, i know), either that or put a sticker over it...

Go into Download Mode. The entire screen other than the text should be BLUE. If the dot still persists, it's hardware.
How to go into Download Mode:
1. Power off the device.
2. Hold Volume Down+Home+Power until a screen comes up with lots of dialogue.
3. Let go of the Volume Down+Home+Power keys.
4. Press Volume Up.
You should then be in Download Mode. Again, if the dot persists, it's hardware.
To get out of Download Mode just hold the same buttons you used to get into it for about 10 seconds - but once you see the screen go black just let go quickly and it should boot up. If you end up getting the Download Mode prompt again, just press Volume Down to resume booting regularly.

Problems on hard reset sequence

Hard reset sequence: Press VoiceDial button + comms manager button + soft reset. You will get a screen with 3 colored bars; at this screen, press the D-Pad UP. (some other version will display a message saying to restore to factory default settings, press the 'Send' button. In this case, press your 'Send'/'Call' button).
seriously, please tell me.. where is the Dial Pad?

Cant help you. My Wizard will show me the other message (rather than the 3 colour screen) and to hardreset, I just press the green-phone/send button.
Thanks Hanmin

YOU HAVE TO GO TO BOOTLOADER MODE !!

to get there:
1)take battery out,
2)put it back in.
3)then you must power up your phone while you HOLD VOLUME DOWN button.

Main Camera Problem - Black and White vertical lines

Hello to you all!
After I've searched a bit in this forum, I couldn't find someone with the same problem.
Issue: When entering in main camera, vertical white/black lines appear, no other image is present. (wide and selfie work as expected)
See attached files.

}
Cause: I filmed a terrible rain with the phone (which was supposed to be waterproof and mil-std-810g compatible), but the next day, the main camera lens, not both back lenses, was steamy, a couple of hours lates, I could only see the previously attached files when opening the camera.
Workarounds tried:
1. Reset to factory settings (no viable result)
2. Reset to factory settings via power menu (Power Button + Vol button), nothing good happened
3. Tried other camera applications --> usually the applications crash when opening them
4. Did some tests via the secret menu, but the results are inconclusive
a. when not moving the phone, all the things pass
b. when moving the phone, some fail, some pass
I was thinking to install another image (the phone is with the original software)
Other things to mentioned: the phone has never been opened, it has sustained other rains and water dives (not salty).
Please advise!
Thank you!
Try replacing the camera module, ebay has them for under 15€
Oh, replying now, it was the camera module, it got wet and didn't worked after. Great phone though.

Lenovo Ideatab A3000F Soft Brick, not booting - Can't entry to Recovery mode/Can't flash stock firmware

I have a Lenovo Ideatab A3000F tablet that worked perfectly until a few weeks ago when I wanted to turn on it and it stayed on the logo.
If I press the power button it turns on and stays on the logo. If I want to turn it off by holding down the power button for a few seconds it turns off, but after a while it turns itself back on, in loop.
To turn it off completely I have to press the reset button that is in the back, under the lid.
By pressing power + vol+ I can normally choose between Recovery/Fastboot/Normal mode but none of them works. When starting it in Recovery mode it is also stays on the logo, and that's the biggest problem...
If I put it to charge it turns on and it is also stays on the logo, the battery icon doesn't even appear.
What I did was download the stock firmware and the flashing tool. I installed the drivers on my pc and the tablet was perfectly recognized, but when I start flashing the rom it stays at 0% when the tablet is with the screen on, and gives me an error when I try it with the tablet turned off.
It is as if there is no connection between the PC and the tablet, but they recognize each other.
Here is a vid of the problem (in Spanish) -> https://drive.google.com/file/d/1RcG_eU-laYpLKYAbJHaSdyt8aMfsBL2A/view?usp=drivesdk and there are two screenshots attached; one screenshot of when it remains at 0% with the screen on, and another that gives me an error when it is off.
Is there any other alternative or maybe something I'm doing wrong?
