Hello guys, i would like to know more about mobile devices (specifically android os), i have a samsung galaxy tab s 10.5 (SM T807V) and when i launch mobile games it would tend to crash alot, and in youtube app it would pause a video frequently for some reason, also a lot of times the tablet's touchscreen won't work, but the buttons work. Now the tablet has been used in the US for 2 years, but it was given to us by our relatives because they can't open it anymore, saying that the battery is malfunctioning which i did not believe at first because it was charging well, and i hard reset the device. Then i downloaded apps and these problems happened, could it be that the battery affected the behavior of the device? or is it something else? i would like to get information and if there are any possible solutions, i will do so. thank you in advance
