My tablet suddenly went crazy

[Mirkorm]

Hi everybody,

I have a Huawei tablet and it worked fine about an hour ago, then I unlocked the screen to use it some minutes ago and it didn't respond, I connected it to the power cord and the battery was drained (there was battery, if I don't go wrong at least 40, and I use it very lightly so the battery usually lasts about a week).

When it finally turned on (I had to press the power button longer than usual, about 10 sec instead of almost instantly switching on when pressing the power button, so I already sensed something wrong was going on) and when it turned on it had the screen that has a smaller portion that is brighter (the same shape of the screen only a bit smaller and centered, like if someone is pressing behind the screen) and the screen continually flickers, like an old pc screen when caught on video or a strobe light and I really don't know what to do.

Thanks

Does the panel on the back feel 'thicker'? If so, the battery might be swelling and I'd advise against powering it on or connecting it to power if that's the case as you need to replace the it.
