[A700] Update destroyed touch screen response

OK so I downloaded & installed the latest OTA update (RV23RC03; 1.057) with the power mode choices, and it has completely destroyed my touch screen response! I previously had ZERO problem with this- every key press registered on both the original ROM and the 1st update. Since the latest update, everything takes 2 or 3 presses, sometimes VERY firmly, many times still without registering. This totally sux
Is anyone else having this issue? I should note that I do have a matte screen protector on; this previously caused NO problems.
Is there an easy reasonably safe way to revert back to the 1st update (RV07RC06; 1.029)? A link and/or instructions appreciated. Thanks.
Acer, are you out there? This exact issue occurred with my A510 on its 1st update, after which it became nearly unusable for me. Since it was < 30 days I was able to return it. No such luck this time. Why are these updates doing this? It's driving me nuts!

No issues with touch on update. It seems to be running better actually.
Try to completely reset thru recovery with wipe data maybe.

That's so amazing. I went from no problem at all, to I can hardly use this any more; only thing that changed was the update.
Can you please be specific about how to reset through recovery. (Step-by-step if possible) and how to wipe data.
Thanks.

You can reset data thru settings/privacy but you will lose everything and start fresh.
I'll check on the other method later on for you.
Also turn up touch sensitivity in settings/display if you haven't...
Edit - it appears that the stock recovery doesnt have those options.
You can still reset by inside ICS like above, or...
Factory Reset:
WARNING: reset will start immediately
Volume button (one dot) and Power button, once buzzes release power button and then toggle the rotation switch on and off a few times

Yes of course, I have set screen sensitivity to high. I think I'd rather go back to 1st update, rather than wipe everything (I do have a backup but it's still a hassle). I can't believe no one else is having this problem.
Any idea how to revert to last update?

Someone in a german android forum mentioned that it help on his device after the update to set the sensitivity to the lowest setting and then back to middle or high.

I tried playing with sensitivity settings, turning on/off,resetting and no luck.
I actually found the ROM from before the update on this website and flashed it as update.zip with vol +power. It worked, I now have 1.029 back and touch screen works perfectly. I'm sorry to lose power management but i think I'll stay where I am . Don't ask me about a Jellybean update; I'll want it but after this I'll be afraid to try it. If anyone has an explanation for this i'd love to hear it.

Long press problem with my s8+ only in the center of the screen.

Hello.
Since a long time i have a big issue with my rooted s8+.
When i want to long press (tap and hold) on my screen to select a text, sometime it works sometime it doesn't work (it do like i pressed the screen and releases it immediately when it does not work as short press).
Until a few days ago i thought it was a random problem.
But i discovered a few days ago that this problem happens ALL THE TIME when i need to long press on the center of the screen and NEVER HAPPENS when i long press on the top or bottom of the screen.
Now when i want to select a text in the center of the screen, i just have to scroll the text up or down and then the long press works.
Does anybody have the same issue on his s8+?
Is there an app to definitly check this issue that happens only on long press and never on short press ?
How can i fix it?
Thank you for your help
(sorry my english is very bad i hope you have understood my question)

Open up your phone app as if you're going to call someone and dial *#0*#
(Star pound zero star pound)
This will get you into maintenance mode where you can trouble shoot many things. Tap on "touch" and drag finger all over the boxes on the screen in the shape of a rectangle with an X through it. This will allow u to see how your phone is responding to touch. Hope this gives u an idea as to where or if the issue is occurring. If not at least it's a pointer for phone issue trouble shooting.
Cheers!

Thank you for your answer.
I tried that and everything is ok on the touch test.
But after this test i just tried to select something on this page and i have the same issue. When i want to select in the center of the screen the tap and hold is not working.
I scroll a little the page and it is working.
It seem it just don't detect that i hold my finger. But detect normally when i just press with my finger.
I think i should send my phone to Samsung.

I just tried with the page i put a screenshot in attachment to this post.
When i try a tap and hold (i tried several times) on the line "i scroll a little the page..." it does not work ( it just select the word on which i have put my finger but i can not extend the selection and i don't have the icon with copy past etc)
But when i tap and hold on the line starting by "of the screen the tap...." and the line starting with "it seem i just don't detect..." everything is normal.

Here's your troubleshooting steps. Try them each one at a time. If #1 doesn't work, then move on to #2, etc, until it's fixed.
1. Reboot phone
2. Clear cache in recovery
3. Start in Safe Mode
4. Factory Reset
5. Reflash stock, factory firmware with ODIN
If none of those fix the issue, then you will need to reach out to Samsung.

I think most that it would be a hardware problem
But as my phone is rooted i will do all that before sending to samsung as i must install a stock rom before sending to Samsung.
But most of all i wanted to know if other people had also this issue.

The steps I gave you actually eliminate it being a software problem, so it narrows it down to hardware.
Let us know if you're able to fix it, or have to send it to Samsung fie repair.

Than you
I will do that in a few days.
But i just thinked about something.
I just updated my samsung firmware on dec 28. And i had this issue before the update.
When updating, for the root, i installed twrp and have done a complete wipe on twrp before installing magisk. (i still didn't find no way to root without wiping, if there is a way please tell me)
I think i have passed all these steps when i have done the update/root process. Am i right?

I honestly don't know. I don't root. So I don't know the steps. Try them anyway, and if you end up having to do a factory reset, don't restore anything. Start completely fresh.
And installing STOCK UNROOTED firmware with ODIN will eliminate any issues associated with root.

Did you try doing a factory reset? You could try that but it sounds as if it is a hardware issue. Get it in to samsung before warranty runs out. Good luck my friend!

remaping

hello everyone
i am hoping that you guys will be able to help me out. i have an xtrons head unit 10.1 inch double din running 5.1 firmware. i reached out to the people that sold it to me about updating to a newer firmware and they told me i can only update the software. they sent me a file that would update my software with instructions. i updated my unit now the back light that lights up the touch buttons does not work neither does the power, volume up, down or home the back button does work but instead of going back it raises the volume. i can not turn the head unit off only when the car ignition gets turned off. i tried to use a remapping app but it doesn't seem to find the buttons that i want to remap. the sellers are not offering any help because it is 3 months past the warranty. xtrons told me the radio is discontinued and are also not offering any help this is what was on the file they sent HH 通用机安卓5.1(20170307)_rk3188_5.1.rar
p.s i also attached a photo of the info that the radio has i am not sure if when i updated it if it changes the info. thanks for any help that you guys can provide

Have you tried going into the factory settings and entering the touch calibration menu?
If you go to settings, factory settings (password is "126" without the quotes) and go to the touch panel calibration there's one to calibrate the touch screen and another one that says "touch panel" or front panel.
Play around with that menu and that should solve your problem.

thanks for helping me as fast as you did. it did work i also found a video on YouTube that might help other with this same problem. https://www.youtube.com/watch?v=I27cjq0SUTk

Question Teyes spro plus steering button issues

Hi guys I have had a teyes spro plus for a couple of months on a vauxhall insignia. I have never been able to get the steering controls to work, when I click on the steering buttons the car comes up with volume icon on the dash clocks and says no audio and when I try to change the canbus to insignia everytime its like it isn't saving the setting and keeps going back to like I haven't set it up. If I reboot the unit and goto steering buttons it flashes up for a second to press a button on the wheel to configure then nothing... everything else works on screen like door opening, climate control, reverse camera ect just not the steering controls..im pretty sure the 4 pin usb hasn't any power either im yet to confirm this with a multimeter. I have updated the unit to the latest firmware but still the same.
Any ideas? Or anything i can try? Thanks

What did reseller and/or installer suggest.
Any info in the teyes discussion post?

I bought it directly from teyes and installed it myself. Ive went through all the connections all seem ok. I've contacted teyes who said it was an issue with the firmware why it wasn't saving wait for the new one which I did but its exactly the same.
Is there a teyes discussion post sorry I've missed it have you a link bud thanks

Don't know if this is related, but the supplied Teyes wiring harness had an unplugged small white connector, I plugged the connectors together and could not get the steering wheel to learn. Unplugged the connector and was able to program the steering wheel buttons.

Hi mate i had same issue, and i manage to fix it.
But we dont have same car, is that spro with newer update from cc2 or?
anyway how to fix it:
You need to install older original Steering control.apk, I manage to extract from older firmware and installed it in newer one. And it works like charm with older program.

Hi guys
My spro plus stopped working since 1 week and I’m unable to find the issue I checked everything changed the 15A also but didn’t resolved the issue. It just shows the black screen when the engine starts and the button lights just turn on and off after few seconds.
I contacted the technical teyes team they said your device is broken.

Dasaita PX6 Unit Bricked?

I recently tried to update the MCU in my Dasaita PX6 head unit. After the update the unit is entirely unresponsive. I looked at the MCU file after I installed it and realized I installed the MCU from another company, not Dasaita. (I realize I should have cheeked this before but I did not and is why I'm in this situation now. Is there anything I can do to fix it? I tried to enter recovery mode, however, the reset button does not work. The screen remains black and the buttons do not light up like they did before the update when the reset button was pressed. Fuses are in good condition. My exact unit is linked here: https://www.amazon.com/Dasaita-Android-Corolla-2014-2017-Carplay/dp/B07XQJH6V6 .
