Please i need your help - touch screen problem

Hello everybody !!
For two days i have a very bad problem, my touchscreen does not respond properly. i must insist on touch screen to choice or do semething.
Before, the screen responded very well but now it's difficult to do anything.
All fonctions of the phone work but touch screen does not respond properly.
In certains area of screen, it's good but in bottom right it's difficult to choice something.
I have clear registry, reinstall firmware and reset factory preset but it's always the same problem.

Please, i need your help to have my meizu work good.
Can i do something to have the touch screen good responding.
Thank you to help me.
I hope there is a solution

Hi,
Umm....im not sure if this might work.If you have an application called Control,click on that and find stylus.click on it and there will be a tab where you can recaliberate.try this and see if the problem still happens...

have a look here, hope this could help:

Broken touch functionality (Any suggestions?)

Thank you for reply
I have read all posts in links have been given but i don't understand exactly what i must to do.
I have tried tu put sticker and plastic on screen for static problem and touch a lot of screen with my fingers but no success.
If someone have the method to do exactly the good things to have screen work perfectly again it would be incredible.
In post i read that :"simply just buy 3M electric wrap, stick on lcd screen (much reach side frame) few time"
I'm french, and what's electric wrap ? Google translation don't help anymore to understand what kind of thing to do.

I thing that Meizu m8 it's a wonderful phone but i live in Réunion island (in indian ocean) and i don't want to send my phone in china for reparing. It would take so much time.
Please, continue to help me and say me simply how to do to try to recover the screen phone.
I hope and i wait some answers and i want to thank you in advance.
Best regards

Maybe it's a connector problem, which would require opening of the phone to fix.

Thank you mbarry for your reply.
Maybe it's a connector problem
