[Huawei MediaPad M5  Questions & Answers] dorpmuller:
I have two devices, the problem is the same on both: when adjusting brightness slider, there is a sudden jump in brightness past a certain point: close to the white area. Right up to that point the screen is not bright enough of course. It will not adjust to a happy medium.

This sucks. The thing is not a joy to use. Tried a 3rd party dimming slider and that did no good.

Root not an option. Power genie can't be disabled. (greyed out)

Could really use some ideas here.

Thanks a lot!

Hi! This is Ivan. ?

Receive a warm welcome to our live chat!

I see.

What kind of issues, Rich?

Rich	08:43:31 am

ok, here's what happens: brightness is not linear. At a certain point, it jumps to a much higher brightness suddenly. There is no middle ground.

Everything is updated btw.

Ivan G	08:44:10 am

Thanks for all the details, Rich.

I will definitely do my best to help you in providing you the correct information about your brightness inquiries for your MediaPad M5.

Rich	08:46:49 am

It suddenly jumps when the slider is at the white area. Of course the brightness isn't enough at the point where it jumps. Auto brightness is disabled btw.

Ivan G	08:47:06 am

I appreciate all the information, Rich.

Let's try the following.

I would recommend you to perform a Wipe cache partition in order to get rid of trash files and glitches on your device.

Rich	08:47:44 am

Hang on

Ivan G	08:47:48 am

Sure thing.

Let me give you the steps.

-Turn off the device.

-Press and hold the UP VOLUME + POWER buttons at the same time. Once you see the logo screen wait three seconds and release the buttons.

-Use the Volume Down button to scroll to Wipe cache partition.

-Press the Power button to select it.

-Once the device completes the cache wipe. Use the Volume Up button to scroll to Reboot system now.

-Press the Power button to select it.

*Your device will restart.

Do not worry, this process will not erase your personal information or applications.

If you are using your device to chat with us right now, you will eventually lose connection.

using enother device.

rebooting..

Ivan G	08:50:04 am

Perfect.

Please let me know if the issue persist, Rich.

Rich	08:52:52 am

it works after i reboot anyway but it always comes back. it's ok now but im not holding my breath.

Ivan G	08:53:45 am

Don't worry, Rich. If the issue remains unsolved you can contact us back and we will find another option.

Rich	08:56:56 am

Other thing is the screen dpi. In developer options the smallest size is 627. I set it at 800 and that's a perfect number. Otherwise the default dpi makes the tablet cartoonish like a kid's device. Trouble is, the setting wont survive a reboot. Any way to change that without rooting?

Ivan G	08:58:28 am

Excellent question. As you may know, it is not recommended to reboot your device due to the fact that you can experience malfunctions in the future.

Rich	09:00:44 am

Awww.. I dont worry about that. I'm very experienced with Android. I've burned custom roms in older devices, rooted, hacked. ?

Ivan G	09:01:11 am

Oh, I see.

That is good to know!

Rich	09:02:24 am

That said, Im not messing with this one. It's perfect except for these issues. Just wanna have the dpi survive reboot. Only reason I root anyway is for adblocking.

Ivan G	09:03:30 am

Not to worry, the wipe cache partition and reset your general settings are excellent troubleshooting steps for your amazing MediaPad M5.

Rich	09:06:08 am

Im appreciative of you... you guys build *really* nice stuff. 'bout time a really good 8 incher was released. Everything else out there is junk except samsung! You did a great job. One more thing... is the m5 gonna get emui 9? (u. s.)

Ivan G	09:06:26 am

We really appreciate your continuous support and preference for our products. Remember that Huawei always gives our customers the best of the best in quality and performance.

Another excellent question, Rich.

I will gladly provide you with such details in a moment.

To do so, I will need your serial number and your build number, please.

Rich	09:07:21 am

Ivan G	09:07:27 am

Please, take your time.

You can find that number on your original box as ''S/N'' or under: Settings > System > About the device > Status > Serial Number.

Build number: Open Settings >Touch System > About device to see your model number, Build number and Android version.
