RUGONE Xever 7 Pro - What should I know before buying?

I've seen the positives, but I want to know the negatives.

I would really like a phone, with the features of the Xever 7 Pro, that doesn't come with the headaches. Primarily a removable battery and 3.5mm jack, which are a MUST for me. Rugged and eSim+dual sim is highly preferable.

I've read through every post on this subreddit pertaining to the Xever 7 Pro and some of the headache-inducing problems I've seen reported include [preinstalled AI apps](https://www.reddit.com/r/ulefone/comments/1unfjx7/android_16_update/), [slow connection speeds](https://www.reddit.com/r/ulefone/comments/1tww9da/rugone_xever_7_pro_and_mediatek_dimensity_7025/), [poor customer service](https://www.reddit.com/r/ulefone/comments/1trht92/i_want_to_return_my_purchase_but_im_not_getting/), and [lack of updates](https://www.reddit.com/r/ulefone/comments/1unfjx7/comment/oz54fxj/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button). In one thread, a user even [equated the phone to Linux](https://www.reddit.com/r/ulefone/comments/1su654i/comment/oi58g9t/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button), which is a positive for some (but not for me).

How substantiated are these claims and is there even more to be concerned about?

I would like this phone. However, if the concerns are valid, it might not be right for me.
