Upgrading OnePlus Five to Oppo Reno4

I upgraded my smartphone OnePlus Five to Oppo Reno4 Pro 5G. The OnePlus Five smartphone has a Qualcomm Snapdragon 835 CPU, while the newer Oppo smartphone uses a Qualcomm Snapdragon 765. I paid 347.17 EUR for the Oppo phone, which I bought at Amazon. I paid 499 EUR in June 2017 for the OnePlus Five, which I bought directly from OnePlus. The Reno4 is not sold worldwide. It seems that it is not sold in UK and in the US. The main reason for the upgrade was that the OnePlus was almost full w.r.t. to storage. The OnePlus only has 64 GB storage. The Reno4 offers 256 GB. Also, RAM increased from 6 GB to 12 GB, which helps when you switch apps.

The first very obvious difference is that the Oppo weights 172g, while the OnePlus weights 153g, the Oppo feels heavier. This only matters if you have the phone in your hand for a longer time. Another striking difference is that the Oppo phone charges very quickly. Within a 5-10 minutes you can charge enough for the entire day. Oppo calls this SuperVOOC charging.

The whole package includes phone, charger, USB earphones, case protector, paper leaflets, SIM card stick. After unpacking the new Oppo phone I had to update four times including a reboot each time. After that I am now at ColorOS 12.1, Android 12, security update 5-Apr-2022. Build number is CPH2089_11_F.71, baseband version Q_V1_P14,Q_V1_P14, kernel version 4.19.1157-perf+.

Reno4 Pro looks nice and noble. User experience using this ColorOS is good. The Reno4 Pro should not be confused with the Reno4 or Reno4 Z: Oppo Reno 4 Pro 5G vs Reno 4.
