I wouldnt pick LDCloud just because somebody already mentioned it, because it was originally built much more around mobile gaming and 24/7 app farming. For account work, the fingerprint side and how the phone behaves after adding a proxy matter a lot more than raw hardware specs. You can, for example, check out an LDCloud Cloud Phone review here: https://gologin.com/blog/ldcloud-review/ . The review tests the service with fingerprint tools and proxies, and it points out where the setup starts causing problems for account work. It also compares LDCloud with alternatives, so youll get a better idea of what else may fit this job better.
A lot of these services look almost identical until you actually start using several phones every day. Then things like connection speed, Android versions, proxy support, and how quickly you can switch between devices start making a real difference. You could, for example, take a look at Redfinger. It has remote Android phones, several hardware tiers, and lets you keep the devices running even when you close the app.
I handle several marketplace seller accounts for different stores, and some of their apps are much easier to manage from Android than from a desktop browser. Keeping separate physical phones for every client doesnt make much sense anymore, so Im looking for cloud phones that can stay online and keep each account in its own environment. A friend suggested LDCloud, but Id rather see what else is available before paying for anything. Which cloud phone would you go with?
