Brand new UMI Plus E screen troubles

ptuku

Hi Sykesy01,

nice to meet you and thank you for giving your contribution to this thread!
Indeed I am almost convinced it is an hardware problem, because even flashing the device with the stock ROM nothing changed..
Now the UMI customer service agreed to change my phone with a new one, so I am preparing everything to send it back, and wait for a new unit.

Just sorry to bother you again, and to go a little bit out of topic, but did you experienced any delay with the charger? I mean, it doesn't look to be that fast, It actually requires almost 3h for the phone to be totally charged..

thank you all for your cooperation, and for giving me your precious help

Hi
But if I correctly remember you didn't flash your phone with SPFT.
Is that right?

Hi MarcinP,

Yes!! Of course, you completely right!!!
My phone was never flashed neither updated or anything else!
It still have the plastic protections on both, screen and back cover

I am a good boy, I've never done that illegal stuff

ptuku

uhm..
just a quik question..

performing a factory data restore from settings > backup & restore will be enough to clean up the phone and restore it to the original settings or do I need to use some deep task?

many thanks for your attention

Hi again,

I want to add a couple of things, because I find this trouble really really strange.
Yesterday evening, before package the device for the shipping, I've pushed aside the screen problem and started to test it deeper with some other app..
I've tried to watch a video on youtube, than to follow online streaming on my national tv app, and than I tried to download and to play some huge game from android (I am not that experienced, but I found that a good test is Real Racing 3 so I tried it) and to read emails and surf the web. Following the results o my text:

- watching some videos on youtube from web browser with default browser and firefox:
videos starts completely full of "squared pixel distortion" like jittering, and also there is one more artifact, the loading wheel is doubled and overlayed (one bigger on the top and the other below) than the jittering finishes and videos are fully clear and sharp. Despite that, if I press the "home" botton, video playback continues to run, so i need to open the browser again and stop the video or pause it, to close the audio. Sometimes it happens that noise effects appears again, but really suddenly.. To be honest, I have to say that with the default browser videos are more affected by the noise.

- watching videos using youtube app:
some jitters on the circle loader and on texts and thumbnails, especially when I scroll the results, but than videos are completely clear and "jitterproof"

- streaming content from national tv provider app:
Absolutely no jitter distortion using the app, neither scrolling pages or viewing contents, and that confused me a bit..

- playing real racing 3:
that shocked me. No jitter. Absolutely no chance to see any noise or distortion, and that made me completely crazy.

- playing sugar crash soda:
same as before, still no trace of jittering.

- running drawing apps (adobe photoshop sketch, adobe photoshop fix and autodesk pixlr)
still without words. Noise sounds like something I just imaged, everything works perfectly and without any distortion.

- reading emails on both, default browser and gmail app:
here it comes (back) the noise. scrolling pages and contents it goes stronger and stronger.

- surfing the web with both, default and firefox browser:
no way. jittering looks like a default option for both. every time I scroll a page or load a content the noise is there, and sometimes it disappear after a couple of sec.. sometimes it looks like there is no chance to stop it.

CONCLUSIONS:
...

I am kind of confused. Still not so convinced it is an hardware trouble.

Hi
Sound is like be software as if is hardware fault this should happen all the time.
Which software you using currently?
Did you flash system to latest ROM with SPFT and did you checked all partitions?

ptuku

Hi MarcinP,

Yes I did, actually my device is running V3.01_ 20161227
I have used SPFT and once finished I have entered the root menu and selected wipe factory data restore.
And here I am, still with that noise..

ptuku

Sorry to ask MarcinP,

but what do you mean with "did you checked all partition"?
I have just used SPFT and then runned a wipe factory into the root menu..
Once finished the phone restarted automatically and asked me to set it up.
Now the version of the firmware is V3.01_20161227 and there isn't any other update..
Is there anything else I have to do?

Many thanks for your availability
