Galaxy M30s - Optimization issues

[AnanduR]

I'm using samsung galaxy m30s for past 6 months.The device is very laggy and many apps are taking so much time to even launch

Main issues are 

1. If i press back on camera,it takes too much time to exit

2. Frequent crashes of apps like Gallery,internet speed meter lite,Applock

Although i highly doubt the update issue you commented.Even if i downloaded corrupted update files,The phone will check the integrity of downloaded files using some checksum techniques like sha1,md5

[Anonymous]

no no it's not corrupt files...it will corrupt..when you will try to bring before announcement of official to your device. from any sites even under Samsung official sites

That's right.The phone will be bricked if that happens.

u can backup your device using smart switch from Samsung

[DarkClawX]

that way , the backup process will take 10 mins even if u have 30 GB data

if the issue is present from day one then u should factory reset the phone
otherwise there must b some app which is causing all the trouble u need to find out which one.
