have you tried to clean up your phone?

If you buy VIVO then only make selfies .. nothing aspect more from this machine. because it has poor hardware. not only 3G even Wifi network signals are too poor to receive.

I've done flashing many times and call into the workshop

the result is nil! no operator factor!

My house 10 meters from the signal transmitter tower may not be a full signal suddenly arrived to 2/3 bar only

If you have some budget then switched to Huawei mobiles or any other china good brand like xiaomi. i never get good news from vivo and oppo users.

@chanalku91 best solution for this is go to the nearest Vivo service center and report your problem with your phone. How old is your phone? if it's still under warranty that will be good since if theres chip problem they can replace it without paying for a fee.

new smartphone 8 days and the first time I immediately activate init.d / busybox and install various tweaks! such as HD performance Ultimate version, DTS, Signal Tweak, Adb flasher, RAM manager & GPU rendering after 5 days tweak it fitted problem happened that can not enter H + network but only get to H
I have also brought to the biggest vivo service center In the city of thorns but they say can not menfix the problem! (probably because the Fastboot & TWRP Safety installed to block Flashing from Computer is unknown) and another way I use Telkomsel operator which gets signal H +

@chanalku91 The problem is in your end, you installed, tweaks your phone that are still in warranty period, so it means that your warranty is voided due to that and I can see that the reason that your phone got a problem is because of that tweaks you installed it might damage or comaptibilty issue.

but the problem is why some operators here get the best signal on my smartphone (h +) like telkomsel and indosat! I'm not sure the problem is tweaked because I tested my smartphone vivo y21L

@chanalku91 Well I think you should change your operator, as you said that other operators signal works fine.
