Samsung Galaxy S4 Mini 故障排除

these problems occur randomly, at the same time. my phone functions proper most of the time.

1corrupted screen

2sometimes tries to boot over and over again, without showing color on the screen

3when this problem occurs, the battery drops down to around 15 % as well

other conditioning of my phone that may be important

the top part of the phone sometimes clicks out, one corner sometimes comes of.

the accu in it is a “Replacement” one. thats whats on the eticet

I use the same SIM for almost 4 years in a row

the charging port has been replaced

I am using the same SD card for over 2 years now, and I used it on my old phone as wel. my old phone was a Samsung Galaxy Young, and it was running Android Gingerbread. that phone died by the infamous ‘boot-loop’. after that, I replaced that phone with the same model, that one had the same fate. the thirth one had that doom as wel. the fourth Samsung G Y I had, was installed with a custom rom and was rooted. it survived the SD card. MY SD card contains corrupted android files

Yesterday a friend’s phone had a virus which sent a link to my phone. I installed a virus clean up but today my phone has gone into negative i.e. there is white text on black background

All the colours are strange and reversed. Also so many programmes are telling me my memory is full which I doubt as I did a complete clean up recently
