Op7pro user here too. Its been 4 years already and at this point im just going to keep using this phone until its unbearable to use. Ive dunked it in river, smashed many back covers. At this point its not about being sustainable or something, but im genuinely interested how long can i withstand replacement. I dont mind having no 5g,since 4g with full bars is pretty fast already. All these phones currently in the market would be very incremental upgrade, unless you’re going flagship range which is around 1k. I want to see smaller phones to come back. Sadly, phone manufacturers are pushing foldables, so it very rare to see any smaller than 5.5" phone for sale. If i were to upgrade now, probably id choose asus zenfone 9/10, pixel 8 with all these promissed 7 year updates.
