Beware of Samsung cuz the modem of Exynos chip is not of good quality and the moden will not work properly in cheap devices like M21 or M11 .
Guys I have purchased m21 recently and since yesterday my phone's internet connectivity is too slow and also wifi also connects but can't work fine. Guys tell me what should I do?
I've downloaded and installed the new update of it . It is the one ui 2.5 update for M21 . And also it has the October security patch update . If you use M21 then go in the seetings and install the new update.
