Android Central Question
I have an unlocked Samsung Note 8 (on Straight Talk's Verizon service). Did the Oreo upgrade using Samsung Smart Switch. As soon as it finished, my 4G LTE disappeared and 3G appeared. Before the upgrade, I was getting 3 to 4 bars of service, now it shows 1 bar, sometimes none. Then 1x pops up frequently. Texting is slow and so is web browsing. Did a hard reset twice and now 3G stays up most of the time with 1 bar of signal. Samsung says it is a carrier issue and not on their end. I spoke to a guy who was in cellular sales and he said it may need a new SIM card from Straight Talk, so I ordered one. I can make calls and text. My phone test app says phone and data is 2G on unknown CDMA carrier. Anyone have an idea on what is going on?
