If you guys faceing hanging & slow perfomence problem with Vivo Y27L than check all your system updates which you will get in system update option . Me too facing same prblm two times but now no prblm with my Vivo Y27L . Its a grt bugget phn in 8K . 1 more thing before you guys buy a Vivo product below 8K you won’t get the real experience of Vivo phn as the lower end use mediatek processor . Choose the vivo product with Snapdragon processors & enjoy
