Brand new NOKIA 5 comes with the following issues:
1) hangs time to time
2) Crashes apps
3) Crashes system UI
4) corrupted SD cards
5) very slow speed
It has these issues any one have any solution because I was asked by Nokia remote technical support to wait foro Android update and now I am no Android 8.1 and my 30 days replacement period is over
This is just a guess, but SD corruption suggests to me that you may have a counterfeit SD card, which could actually in turn be responsible for many other symptoms. Did you get your SD from a reputable retailer, and good brand? Additionally, if you are using it for adopted internal storage, a card with A1 U3 V30 ratings (e.g. SanDisk Extreme) is strongly recommended; slower cards are likely to cause general performance problems.
