Notification bar randomly pulling down

I have the same issue. I only noticed it since the last update, but as I read here, some of you say it´s a hardware issue. I think Umi should say something about this issue, since there are many of us who have it.

No i have not recieved any more updates sadly. The random notification bar "pulling" still happens. However, i have noticed when the "pulling" happens and you reboot your phone during it, the notification bar "pulling"doesn't happen for around 24h. Then it starts again, reboot, 24h without the notification bar "pulling". It's not a neat solution, i mean it shouldn't happen at all. I now do the reboot every morning inorder to have a phone that acts normal for the day. Tempted to go back to my older phone.

Has anyone contact the Umi technical support? I´ve written them, but didn´t get an answer yet.

I try it againe. Your Digitizer(Touchscreen) is DEFECTIVE, BROKEN , DAMAGED, MALUFUNCTIONING , call it what you want.
But there is a solution, it's just not for the long run. You need to give your Digitizer an electric impulse. Just use a quarz igniter from a lighter.
Shock the part of screen a few times, which has the "Ghosttouch/Phantomtouch". There is a possibility that this procedure can damage your phone.
The best choice would be to contact your vendor and get an replacement/repair.

How come U can be so certain in this. It's not only two or three guys having the same issue. I belive there are quite a number of people having the same problem, plus not in the same part of the globe. If it's a hardware we need to push UMI guys to refund or to replace those phones, or fix it ASAP if the problem is in the firmware

What do you expect from a 200$ phone with up-to-date-hardware? They try to save some $ with low quality parts. Parts that are not obvious at the first sight. In this case UMI propably used a cheap poor quality digitizer. How many people do check the precision of their touchscreen?If you want to know more about this problem just use google "Ghost/Phantom Touch Touchscreen". Many cheap chinese phones/tablets suffer from this problem.

First of all no, UMi doesn't try to reduce the production costs with cheap parts. You hardly can find any kind of capacitive touch screen devices, that have never faced the ghost touch issue. The most expensive models are not different.
Some examples:

So it sometimes happens and it's a hardware related issue of course, or all handsets would be affected.
To perform a low level test on the touch panel, I suggest you to boot your phone into Factory Mode by powering it on with the volume down button keeped pressed. Go to Item Test --> Touch Panel amd run both the CTP and FreeMode tests. If you you experience ghost touches even in factory mode, then your touch panel should be repaired or replaced. If no issues in factory mode, under Android you can try to tweak the touch panel with SGS Touchscreen Booster by reducing the touch sensitivity (higher value) or decresing the minimum motion (higher value).
Don't expect that, a software update will fix the behavior of your non-standard quality touch panel. It might happen or not but it's impossible to process it wit intention.
If no one of the solutions mentioned in this thread can fix your touch screen, that's better to contact your seller and request your phone to be repaired or replaced.
